Caller abort reasons are preserved; logical deadlines throw +`ModelDeadlineError`. SDK request timeouts may be retried, whereas logical +deadlines/cancellation are terminal. Wait listeners and timers are released. +Streams are retried only during SDK request establishment, never after stream +iteration begins, even if only provider metadata has arrived. SDK timeout details +are SDK-version-dependent; use a logical deadline to bound the full stream. + +There is also an Agent-level retry wrapper. Harness-controlled Agents now default +that wrapper to zero retries; explicit `Agent({ retry: { maxRetries: ... } })` opts +in. Standalone Agents preserve their prior defaults, so set +`retry: { maxRetries: 0 }` there when the host owns retries. Model `maxRetries` and +`sdkMaxRetries` remain separate from the Agent setting. + +Accounting distinguishes a logical operation from its observed SDK invocations. +`attemptVisibility` is `physical` only with `sdkMaxRetries: 0`; otherwise it is +`opaque`. SDK-internal retries cannot be counted accurately by Agentium. Harness +model-call budgets and model telemetry count logical calls, not HTTP attempts. +`ModelUsageError` exposes usage from a response that failed normalization or +completion validation; harness reservations reconcile this evidence too. + +`OpenAIConfig.endpoint` accepts `auto` (default), `responses` (required), or +`chat_completions`. `fallback` accepts `compatible` (default) or `error`. +Unavailable Responses endpoints now fail if Chat Completions would disable +reasoning, lose provider replay, or drop Responses-only reasoning/cache options. +Requiring Responses never falls back. Explicit Chat Completions also validates +compatibility before transport. This intentionally replaces the previous silent +reasoning downgrade on some model/tool combinations. + +`ModelCapabilities` is a host-supplied interface, independent of any registry: +`contextWindow`, `maxOutputTokens`, `tools`, `reasoningEfforts`, `reasoningModes`, +and `historyEviction`. Supply `capabilities` to either adapter and optionally +`unknownCapabilities: "error"`; the default permits unknown fields. Strict mode +requires context/output limit facts and facts for explicitly requested features. +Known output limits also cap omitted adapter output defaults. +`validateModelRequest()` exposes the same preflight checks for other adapters. +Configured incompatibilities fail before transport. Context sizing is an estimate +unless the host supplies an authoritative tokenizer/bound; provider enforcement +is authoritative.

Decisions include action, selected model role and active tool count. Success, failure and cancellation close their spans. Observation failures do not control execution. Prompts, output text, controller explanations and tool arguments are omitted from these events. Use this bus with its own collector when observing the harness. Do not attach the same tracer or metrics collector to both the harness bus and the wrapped Agent bus: those layers share execution IDs and describe overlapping work. Direct provider calls that bypass the execution services also bypass runtime budgets and telemetry; custom drivers should use the services. Transport/toolkit-specific tracing remains available on their existing buses. + +### Resource budgets and finishing work + +`HarnessRuntime` reserves projected input plus output before submitting each model +call. Input includes the projected messages, tool schemas, and opaque provider +continuation. A synchronous `estimateInputTokens({ provider, messages, tools })` +option can supply a provider-specific conservative bound; the default estimator +is advisory. Output is capped to the available balance after projected input. +Concurrent task, control, and finishing operations share admission. Call slots +are reserved before controllers/context projection, and released on preparation +failure without consuming a logical call. + +```ts +const runtime = new HarnessRuntime({ + driver, + grants: { toolIds: [], modelRoles: ["main", "finisher"] }, + models: { finisher: { provider: model, options: ["maxTokens"] } }, + budgets: { + maxModelCalls: 12, + maxTokens: 80_000, + finishingModelCalls: 1, + finishingTokens: 6_000, + }, + completionPolicy, +}); +const handle = runtime.start("task", { identity, sessionId }); +console.log(handle.budget.tokens); // limit, used, reserved, remaining, + // finishingReserved, ordinaryRemaining +``` + +Snapshots are available from `handle.budget`, `services.budget`, and +`result.budget`. Counts use logical model calls, tool attempts admitted by policy, +and total input + output tokens. `null` limits/remaining mean unlimited. +`remaining = max(0, limit - used - reserved)`; `finishingReserved` is the protected +uncommitted remainder inside that total, and `ordinaryRemaining` excludes it. +Known usage replaces projected token reservations, including late usage after +cancellation. Reservations are always released. Requests that started but have no +complete usage consume their projection conservatively and increment +`unknownUsageCalls`. Reported `result.usage` remains actual received evidence; +it can differ from conservatively charged `result.budget.tokens.used`. + +A trusted driver or completion controller can call +`services.finishModel("finisher", messages, { maxTokens: 2_000 })`. This explicitly +uses finishing capacity (plus available ordinary capacity), requires a granted, +explicitly bound role, and only accepts complete tool-free responses. Returning +that candidate from the driver still invokes `completionPolicy`; finishing does +not bypass evidence validation or authorize tools/effects. Ordinary work and +repeated budget denials cannot consume the finishing reserve. No extra allowance +is added above the configured total. + +These are per-run projected resource budgets, separate from core's store-backed +currency reservations. Actual provider overages are recorded and reduce future +admission; estimates cannot guarantee a hard physical-token ceiling. Unknown SDK +retry consumption is not visible here. For a strict host bound, supply conservative +input estimates, bounded outputs, disable internal retries, and choose an explicit +host retry/accounting policy. An unlimited token budget without a maxTokens value +cannot conservatively bound unknown output usage. + +### Resident history and host archives + +Request context projection still leaves canonical records intact. Opt into +`residentHistory: { maxMessages, maxBytes?, archive, canEvict? }` to move old closed +turns from resident memory into a host-owned archive. `archive.write(scope, +reference, messages)` must acknowledge storage before resolving; +`archive.read(scope, reference)` returns the original records. No storage backend +is bundled. References include a conversation ID, count, and SHA-256 digest and +are persisted as `HarnessSessionSnapshot.archivedHistory`. + +Limits apply per conversation at model/session boundaries. Whole user turns are +atomic, including every parallel tool call/result and opaque replay item. Host +instructions and the latest turn stay resident; an oversized indivisible turn +fails with `HistoryRetentionError`. An archive failure leaves local records intact. +The failure snapshot retains evidence even when it cannot fit the requested limit. +Closed OpenAI Responses/Anthropic replay groups are supported. Unknown opaque +payloads require an explicit `canEvict` host attestation or provider +`capabilities.historyEviction: "closed_turns"`; an explicit `"unsupported"` rejects +eviction. Never declare support for providers that require evicted continuation. + +`services.history` is the resident replay window; `services.archivedHistory` lists +archive references. Retrieve a reference using `services.retrieveHistory(id)` in +an active run or `runtime.retrieveHistory(identity, sessionId, id)` between runs. +Retrieval verifies count/digest and tool structure; it does not automatically insert +retrieved records into trusted model context. The host can present retrieved +records as source data through its context policy. Built-in Agent loops release +evicted initial/transcript copies. Custom drivers own their extra copies, and +parallel active child conversations have independent resident limits. Completed +child transcripts are archived in full at successful session commit. Archive reference +metadata, host storage retention, and aggregate limits across many sessions remain +host responsibilities. Without this opt-in, existing full-history behavior remains. + +### Public input prevalidation + +Import `parseRunInput`, `validateRunInput`, `RUN_INPUT_LIMITS`, and +`HarnessInputError` from `@agentium/harness`. `parseRunInput(encodedJSON)` bounds +UTF-8 bytes before parsing and validates a JSON-encoded **MessageContent value**, +not an entire reply envelope. `validateRunInput(unknownValue)` returns a validated +copy using exactly the rules enforced by `start`, `send`, and `reply`. + +The frozen limits expose `maxEncodedBytes`/`maxNormalizedBytes` (65,536), +`maxQuestionBytes` (32,768), and `maxChoices` (100). Bytes include JSON quotes and +escaping; the encoded limit also counts whitespace. Validation permits empty +strings but requires nonempty arrays of strictly shaped content parts. Media +payloads are shape-checked; provider-specific media support remains a later check. +Prevalidation does not claim a pending request. Run state, request correlation, +already-resolved replies, cancellation, and timeouts are rechecked atomically when +`reply(requestId, value)` consumes it. + +Session snapshots persist conversation/state; they do not restore a live run. +Durable recovery requires versioned execution checkpoints, pending-input state and +safe continuation of effects. That work is deferred, as is paged skill-reference +retrieval: the current built-in skill tool still reads whole files. A future paging +contract should include stable offsets/revisions and truthful omission markers. diff --git a/packages/harness/src/__tests__/package-consumption.test.ts b/packages/harness/src/__tests__/package-consumption.test.ts index a26ffe9..bc17e9c 100644 --- a/packages/harness/src/__tests__/package-consumption.test.ts +++ b/packages/harness/src/__tests__/package-consumption.test.ts @@ -88,6 +88,13 @@ it.skipIf(!enabled)( for (const name of ["createTwilioCallProvider", "createTelnyxCallProvider", "createExotelCallProvider", "createSignalWireCallProvider", "createVonageCallProvider", "createLiveKitSipCallProvider", "OutboundCallService"]) { if (typeof telephony[name] !== "function") throw new Error("Missing telephony export: " + name);

(usage.reasoningTokens / 1000) * p.reasoningPer1k : 0; -// Missing cache price later falls back to prompt price * 0.5. -``` - -`packages/core/src/models/providers/anthropic.ts:438–444` uses exclusive ordinary input as if it were the inclusive prompt total. Its stream retains only `message_start.usage.input_tokens` at line 293. `aws-claude.ts` repeats this loss. `cohere.ts:232–237` reads the native v2 `usage` object at the wrong depth. - -`packages/core/src/agent/agent.ts:836` records only after main execution and reflection finish: - -```ts -const entry = this.config.costTracker.track({ - runId: ctx.runId, - agentName: this.name, - modelId: this.config.model.modelId, - usage: sourceUsage, - sessionId, - userId, -}); -``` - -This loses leaf identity and can lose already consumed usage when later work fails. `llm-loop.ts:196` finalizes the first finish chunk, `llm-loop.ts:631` keeps the latest usage, and `agent.ts:1109` adds every finish usage. These semantics conflict. - -`packages/core/src/cost/cost-tracker.ts:57–58` discards entries above 10,000. Its budget and summary methods read only that array. `agent.ts:261` omits scope IDs during mid-run checks. `cost/types.ts` has no tenant, attempt, catalog version, cache-write quantity, or unknown-cost state. - -`packages/observability/src/accounting.ts:199–208` deliberately replaces a run total: - -```ts -const delta = value - target.cost; -target.cost = value; -this.totals.total_cost_usd += delta; -``` - -Do not change `cost.tracked` into per-attempt amounts while this contract exists. - -### Existing behavior to preserve - -- `events/event-bus.ts:63–78` isolates observer exceptions. Accounting must not undo this protection. -- OpenAI Chat Completions already waits for its usage-only stream tail in `models/openai-api.ts:749–758`. -- Handoff source cost is recorded before delegated usage is merged. Preserve one-charge-per-leaf behavior. -- Local structured-output parsing in `llm-loop.ts:379–387` does not make a repair request. Do not invent a charge for it. -- Explicit zero tariffs, such as a documented free output category, are valid. - -## 4. Internal design - -```text -Provider request attempt - -> usage evidence + actual billing context - -> versioned normalizer - -> canonical usage + required billing measurements - -> matching catalog rules - -> exact charge calculation - -> stored assessment - -> budget settlement + run projections + observation events -``` - -Suggested internal layout; these are modules inside the existing package: - -```text -packages/core/src/cost/ - types.ts Public records and interfaces - usage.ts Validation and aggregation invariants - measurements.ts Meter definitions and coverage validation - calculator.ts Pure exact arithmetic - catalog.ts Deterministic rule matching - catalog-data/ Reviewed provider/model rules and source metadata - accounting.ts Attempt recording and assessment lifecycle - context.ts Explicit accounting context propagation - budget.ts Decisions and reservation orchestration - store.ts Optional UsageStore and BudgetStore contracts - stores/in-memory.ts Local implementation - stores/sqlite.ts Durable single-host implementation - stores/postgres.ts Durable shared implementation - cost-tracker.ts Public facade and compatibility projections - pricing.ts Deprecated legacy pricing bridge - __tests__/ Fixtures and contract tests -``` - -Do not create a framework of empty classes. Start with pure functions and a small accounting coordinator. Provider normalizers should not import database drivers or fetch prices. - -## 5. Canonical records - -### Identity and context - -Separate a logical operation from its actual request attempts. - -- `operationId`: one requested activity, such as answering or creating embeddings. -- `attemptId`: one observable leaf provider request. Each retry gets a new ID. -- `parentOperationId`, `runId`, `rootRunId`, `parentRunId`: attribution without charging parent summaries. -- `tenantId`, `sessionId`, `userId`: trusted scope from execution context. Use a defined local namespace when tenant is absent. -- `providerRequestId`: provider evidence when available. It is not the only deduplication key. -- Requested route/model and actual provider/model/resource are separate. -- `billingProviderId`: who charges the account; distinct from wire-format compatibility and model author. -- `api`: Chat Completions, Responses, Decisions, Messages, Converse, GenerateContent, embeddings, speech, or a provider extension. -- Requested and actual service tier; reasoning mode and effort; region; context band inputs; cache duration; account price-plan identifier. -- Record provenance for context: response, request, documented default, configured contract, or unknown. Do not turn a missing returned tier into Standard without a verified default rule. -- No credentials, authentication headers, prompt text, or full responses belong in accounting context. - -Each attempt has independent `executionStatus`, `usageStatus`, and `pricingStatus`. A successful answer can have unknown usage. A failed answer can have complete usage. Keep those states separate. - -### Usage contract - -The intended shape is additive to the old display fields during migration. The following illustrates the contract; implementation must define exact exported types and validators. - -```ts -type TokenCount = number | null; - -type CanonicalTokens = { - input: { - total: TokenCount; - ordinary: TokenCount; - cacheRead: TokenCount; - cacheWrite: TokenCount; - cacheWriteByTTL: Array<{ ttlSeconds: number; tokens: number }>; - }; - output: { - total: TokenCount; - reasoning: TokenCount; // A diagnostic subset of canonical output. - }; - total: TokenCount; - providerReportedTotal: TokenCount; -}; - -type Measurement = { - id: string; - meter: string; // e.g. token.input, token.cache_read, token.cache_write - unit: string; // token, request, second, character, image, token-hour... - quantity: string | null; - dimensions: Record; - source: "provider" | "derived" | "measured" | "estimated"; - evidencePaths: string[]; -}; -``` - -Token counts must be finite, nonnegative safe integers. Generic quantities and money use validated decimal strings. If a provider exceeds safe integer limits, reject unsafe conversion and record an invalid observation until supported; do not silently lose precision. - -Required rules: - -1. Canonical input includes ordinary input, cache reads, and cache writes. Canonical output includes reasoning. These definitions stay fixed across providers. -2. OpenAI output already includes reasoning. Google candidates and thoughts require the API's documented mapping into canonical output. Anthropic ordinary input needs reads and writes added to produce inclusive input. -3. Preserve the provider's total separately. If known canonical components disagree with it, record the discrepancy and retain evidence. Do not force equality by clamping values or inventing a residual charge. -4. Cache-write total and its TTL buckets describe the same tokens. Charge the detailed buckets OR the total, never both. Missing TTL split with different rates means that write charge is unpriced. -5. Modality fields and reasoning are often subsets. A text/audio split must partition its parent before separate rates can be applied. Independent cache and modality marginals do not establish their intersection; mark unknown cells instead of guessing. -6. Missing is `null`. A normalizer may use zero only when the provider contract for that API/version establishes zero or non-applicability. -7. Preserve a bounded, validated copy of raw usage and the safe billing metadata needed for replay. Do not copy a whole model response into the store. Mark truncation if storage limits prevent complete raw retention. -8. Store schema version, normalizer ID/version, and normalization issues. Renormalization creates a new revision. -9. Totals for heterogeneous operations are views. A sum of token counts from different models is a usage statistic, not a price input. - -### How the charges array is produced - -The adapter supplies measurements and a coverage declaration: known meters, required-but-unknown meters, and unsupported billing features. The price catalog selects the applicable rule for each required meter. The calculator then emits a charge or an explicit unpriced item. - -```text -raw usage - -> normalizer produces input/read/write/output measurements - -> context and capabilities identify any extra required meters - -> catalog resolves the rule for EACH meter - -> calculator creates charges[] with rate and evidence - -> assessment reports complete, partial, or unpriced -``` - -Do not price every numeric field in raw usage. Do not assume a missing array entry means the provider had no additional billable work. Preserve unknown additional fields and flag unknown billing semantics. - -Each priced charge stores: - -- measurement ID and meter, original quantity, billed quantity, unit, and dimensions; -- rule ID/version, catalog version, source URL, verified date, and effective interval if known; -- exact price amount, currency, price denominator, and any quantity rounding/minimum; -- amount before and after explicit adjustments, with the rules and order used; -- charge inclusion scope, so reported provider totals and child charges cannot both enter a total. - -Each unpriced charge stores `amount: null` and a machine-readable reason such as `missing_usage`, `missing_rate`, `ambiguous_rate`, `missing_context`, `unsupported_rule`, or `invalid_usage`. - -Assessment fields include `knownSubtotal`, `total` (null unless complete), `unpricedCount`, `pricingStatus`, and `basis`. A known subtotal must never be labelled the final total. Keep currencies separate; currency conversion requires a separately sourced FX assessment. - -Assessments also declare their target (`attempt`, `billing_group`, or `account_period`) and finality (`provisional` or `final`). A fully priced partial session remains provisional. Attempt measurements that contribute to a group-priced meter are labelled contributions; they do not also produce independent payable charges for that meter. - -### Worked example with reads and writes - -These are synthetic quantities and rates for a fixture, not a current provider tariff. - -Raw inclusive input is 15,000, including 12,000 read tokens and 2,000 written tokens. Output is 500, including 100 reasoning tokens. Total is 15,500. - -| Meter | Quantity | USD per million | Amount | -|---|---:|---:|---:| -| Ordinary input | 1,000 | 10 | 0.010 | -| Cache read | 12,000 | 1 | 0.012 | -| Cache write | 2,000 | 12.5 | 0.025 | -| Output, including reasoning | 500 | 50 | 0.025 | -| **Total** | | | **0.072** | - -The ordinary input measurement is `15000 - 12000 - 2000 = 1000`, only because this fixture's normalizer declares an inclusive input total with disjoint cache categories. The reasoning detail produces no additional charge. - -```json -{ - "pricingStatus": "complete", - "knownSubtotal": "0.072", - "total": "0.072", - "currency": "USD", - "charges": [ - { "meter": "token.input", "quantity": "1000", "amount": "0.01" }, - { "meter": "token.cache_read", "quantity": "12000", "amount": "0.012" }, - { "meter": "token.cache_write", "quantity": "2000", "amount": "0.025" }, - { "meter": "token.output", "quantity": "500", "amount": "0.025" } - ] -} -``` - -The stored charge also contains its full rate snapshot and evidence fields. If the write rate is missing, the known subtotal becomes `0.047`, total becomes `null`, and the write item becomes unpriced. If the write rate is explicitly zero, the assessment can remain complete. - -For an Anthropic-shaped fixture with ordinary input 1,000, reads 12,000, writes 2,000, and output 500, the same canonical counts result without subtracting reads from ordinary input. - -## 6. Pricing rules - -### Match on billing facts - -Use provider/biller, exact resource/model identity, API, effective time, account contract, actual tier, applicable mode, region, context size, modality, cache duration, and meter dimensions. A field can be ignored only when the rule explicitly applies to all values of that field. - -Resolution order: - -1. Applicable explicit account contract/override with version and scope. -2. Exact provider/resource/API rule. -3. Explicit reviewed alias or deployment mapping to a rule family. -4. No match: unpriced. - -At the same precedence, overlapping matches are a catalog error. Never select the first rule by insertion order. Remove general substring matching. Do not infer Azure deployment prices from its arbitrary deployment name. - -Rules declare their required context. Use inclusive per-request input to select a context band when that provider requires it. Distinguish whole-request band changes from marginal tiered pricing. Do not use run-aggregate tokens to choose a request's band. - -### Supported rule forms - -- Unit price: quantity × price / denominator. -- Block rounding: provider-defined rounding and minimum units, applied at the specified request/session/account scope. -- Whole-request bands and marginal tiers, represented separately. -- Fixed operation fee with an explicit billable occurrence. -- Duration/integrated storage price, with start/end or provider-reported resource-time quantity. -- Explicit adjustments limited to named charge IDs/categories and a documented order. -- Provider-reported monetary amount, with currency and included scope. - -Use a small validated rule union and pure evaluators. Do not execute expressions from fetched JSON. A custom calculator extension is trusted application code, registered explicitly with an ID/version; its output must pass the same validation and provenance checks. - -Use exact decimal or rational arithmetic throughout. Decide the library in phase 1, put it behind one internal helper, and declare any imported library as a direct core dependency. Do not rely on a transitive dependency. Round for provider rules or presentation only, not to cents on every tiny call. - -Base quantities and tariffs are nonnegative. Represent refunds and credits as explicit signed adjustments with their own source and scope; do not smuggle them in as negative token counts or negative base rates. Record the evaluator's precision and rounding policy version. Division by a non-decimal denominator must have a specified rational or precision policy, with fixtures that reproduce the stored result. - -### Fast, Ultrafast, Pro, and other modes - -Store `requestedServiceTier`, `actualServiceTier`, `reasoningMode`, and `reasoningEffort` separately. Use a supported combination's own rules. For OpenAI's documented Fast downgrade, the actual returned default tier selects Standard rates. Pro's aggregate usage is counted once; no universal Pro multiplier. A separate Pro model ID uses its own rule. - -Do not multiply hosted-tool charges merely because token prices have a speed premium. Record batch/flex/cache/modality/region compatibility as provider rules, including when combinations are unsupported. Missing actual tier can be priced only under a documented fallback/default with recorded provenance; otherwise it remains unpriced. - -### Catalog maintenance - -Ship a reviewed, versioned catalog inside core. Keep data separate from evaluators. No price fetch belongs on the model request path. Permit the application to supply a pinned catalog or contract override. - -Every update requires source URL, retrieval/verification date, model/API scope, applicable dimensions, and fixtures. Keep `verifiedAt` distinct from `effectiveFrom`; retrieval time is not proof of a tariff's start date. Do not backdate a current tariff onto historical calls without an explicit approximation label. - -Community datasets can identify candidate updates. Confirm supported billing rules against primary provider sources before marking coverage complete. Maintain a catalog validation command/test that detects overlapping rules, negative/invalid prices, missing denominators, unsupported dimensions, and invalid aliases. Expiry policy must be explicit: old rules are reproducible but may be stale, not automatically current. - -### Costs that are not per-call prices - -Taxes, credits, monthly commitments, provisioned throughput, subscriptions, and negotiated account adjustments can require account-period data. Store them as separate period assessments or adjustments with an allocation policy. Do not fabricate per-call token rates. Display list-price estimate, provider-reported charge, and reconciled invoice amount as separate views. Never add them together as independent costs for the same scope. - -### Billing groups and rounding scope - -Use a billing group when a provider rounds or applies a minimum across several observations. Its key includes tenant, billing account or resource, meter/rule identity, required grouping dimensions, and the provider-defined session or billing interval. Keep rate/effective-time boundaries explicit. Membership references observation IDs, so replay cannot add the same quantity again. - -Accumulate the group's measurements first, then apply its minimum/rounding once. Use the latest selected snapshot per contributing attempt/resource interval or each unique delta, according to the normalizer contract; do not sum cumulative observations. Store group usage revisions, immutable assessments, and one selected assessment per view. Late observations create a new revision and replace the selected assessment through the same atomic projection transaction used for attempt corrections. They do not append another full charge to spend. Open groups are provisional; closed groups can still receive explicit corrections with retained history. - -Example fixture: two distinct operations each report 20 seconds in the same session. The tariff charges USD 0.01 per started minute at session scope. Combined duration is 40 seconds, billed duration is 60 seconds, and the single selected group charge is USD 0.01. If the tariff instead rounded each request separately, the total would be USD 0.02. Test both, plus replay, late duration, and rule-boundary cases. - -Account totals include the group charge once. Per-call/run attribution is a separate versioned allocation view, never another payable charge. Default to unallocated group cost when no allocation policy exists; affected call/run views disclose incomplete attribution. An optional duration-proportional policy can allocate USD 0.005 to each of the two calls. Allocations must sum exactly to the group amount with a deterministic remainder policy. Parent views use allocations OR the original group charge as appropriate, never both. Reservation bounds must include potential group minimums; uncertain open groups retain a conservative hold until settlement policy allows release. - -## 7. Request lifecycle - -Meter at the leaf adapter request boundary. Routing and fallback wrappers carry parent context; they do not create another spend row for returned child usage. - -1. Allocate stable operation/attempt IDs. Persist a start intent when durable accounting is enabled. -2. Check budget policy; reserve if supported and required. -3. Submit the provider request. -4. Capture safe request/response identity and raw usage before validating model output. -5. Merge usage observations under that API's rules. -6. Normalize, assess, and settle the attempt even if output parsing, a later tool, or a hook fails. -7. Persist the selected assessment and budget settlement. Emit observation events afterward. -8. Return model output or the original execution failure. Accounting errors have a distinct type/status and cannot enter model retry classification. - -Keep record creation outside the retry callback for completed provider work. A failed store write retries the write using the same attempt/assessment IDs. It must never repeat a successful model request. A pre-dispatch durable-store failure can prevent a new request; a post-response failure records an accounting warning and blocks later work only according to policy. Do not throw a generic retryable model error after receiving the answer. - -### Retries and visibility - -Agentium retries and SDK transport retries must have one clear owner. For built-in adapters, prefer configuring SDK retries off and using a common metered retry primitive with existing retry eligibility/backoff preserved. Verify each installed SDK first. Where transport hooks give reliable attempt events, they can be used instead. - -Do not silently change retry counts during extraction. Add fixtures showing equivalent retry behavior and separate attempt records. For custom/opaque SDKs where internal attempts cannot be seen, record `attemptVisibility: "opaque"` and the observed invocation. Do not claim physical-request completeness. A timeout alone establishes neither zero charge nor confirmed charge. - -### Streaming - -Introduce an internal usage-observation contract with `kind: snapshot | delta`, a stream/attempt identity, and a stable sequence or event ID. Support field-specific cumulative updates where the API defines them. Snapshots replace prior values for the same measurement. Deltas add once. Stale/duplicate revisions do not change totals. - -Finish of content is different from final usage. Read usage independently of text/tools. Finalize after the transport closes or reaches its authoritative terminal usage event. Preserve the last known partial usage if cancellation/error happens first. Missing final usage means partial/unknown, not zero. - -Keep public stream compatibility through an adapter while migrating consumers. Do not delay tool safety decisions or execute incomplete tools just to obtain more usage. For long-running realtime sessions, settle per response/turn or resource interval, not only at disconnect. - -### Operation tree and extra model work - -Meter answer generation, reflection critics/revisions, compression, compaction, tool selection, tool-result summarization, memory jobs, team planning/synthesis, workflow model steps, and child agents. Carry explicit accounting context through helpers; do not put request-specific mutable state on a shared provider instance. - -Optional async-local context can help carry context inside an execution, but public/custom-provider boundaries must support explicit context and isolated concurrent runs. A wrapper over an already-metered provider must detect the existing attempt and avoid another charge. - -Sum selected attempt charges and applicable billing-group charges by distinct charge ID. Group contributions are not payable attempt charges. Parent views report `ownCost` and `inclusiveCost` where needed, plus completeness and unallocated group amounts. They are not payable entries. Background memory work can finish after the initial run result; expose snapshot/as-of metadata and an explicit `flush`/drain operation instead of presenting an immutable final total too early. - -## 8. Storage model - -Use these logical entities; implementations can store JSON with indexed columns. - -| Entity | Identity and contents | -|---|---| -| Operation | `(tenantId, operationId)`; parent/run attribution, kind, purpose, safe requested context. | -| Attempt | `(tenantId, attemptId)`; operation reference, ordinal, start/end, execution state, actual identity, request ID. | -| Observation | `(tenantId, attemptId, observationId)`; sequence/kind, raw usage, safe billing context, time, evidence status. Immutable. | -| Usage revision | `(tenantId, attemptId, revision)`; observation references, schema and normalizer versions, canonical usage, measurements, issues. | -| Billing group | `(tenantId, billingGroupId)`; account/resource, rule/grouping key, interval, unique observation membership, usage revisions, open/closed state. | -| Assessment | `(tenantId, assessmentId)`; target kind/ID and usage revision, catalog/rule versions, charges, total/completeness/finality, purpose: original/reprice/reconcile. Immutable. | -| Selection | `(tenantId, targetKind, targetId, view)`; current assessment for an attempt, group, or account period. Never sums all revisions. | -| Allocation | `(tenantId, assessmentId, allocationPolicyVersion, targetOperationId)`; derived share of a group/period amount. A reporting projection, not new spend. | -| Budget reservation | `(tenantId, reservationId)`; applicable scope keys/period, attempt, reserved quantity, state, reconciliation/expiry policy. | - -Store ISO UTC timestamps and decimal strings. Do not depend on `Date` instances surviving JSON storage. Scope all keys and queries by tenant. Use opaque account identifiers, never keys or secrets. - -Minimum query access paths: tenant+attempt; tenant+run; tenant+rootRun; tenant+session+occurredAt; tenant+user+occurredAt; tenant+provider/model+occurredAt. Cursor paging is required. Separate distinct operation/run counts from entry/attempt counts. - -### Store interfaces and implementations - -Define optional `UsageStore` and `BudgetStore` in core. Do not add mandatory methods to every existing `StorageDriver`. - -- `UsageStore`: append observation with duplicate/conflict result, append usage revision/assessment, atomically select a revision where supported, query by cursor, aggregate selected assessments, and report durability/capabilities. -- `BudgetStore`: atomic reserve-if-available across all applicable scope keys, settle, release when confirmed safe, query, and reconcile uncertain reservations. -- `InMemoryUsageStore`: default local operation, no restart durability; its history eviction must not lower active budget totals. Explicit budget periods bound retained aggregates. -- SQLite: first durable local implementation. Transactional observation/selection/projection updates and schema migrations owned by cost storage. -- Postgres: shared-worker implementation with unique keys and atomic budget reservations. Reuse optional SDK configuration patterns; no mandatory database dependency. -- Existing generic KV storage may provide an explicit limited archival adapter. It must declare no atomic shared budgets and must not claim full historical aggregation if listing/pagination/retention cannot be proven complete. Do not auto-enable it for strict budgets. - -For shared reservation budgets, both interfaces must come from one transaction-capable accounting backend. Require an idempotent `commitAssessmentAndSettle` operation that inserts the immutable assessment, compares the expected selection revision, updates every affected scope projection, and settles applicable reservations in one transaction. Its key includes tenant, target kind/ID, assessment, and revision. Concurrent admission reads those same committed budget rows. Reject independently configured usage/budget backends for this mode; two successful individual writes do not provide atomic settlement. Separate archival stores are allowed only as downstream copies. - -Use a duplicate key for repeated delivery of the same observation. Reusing the key with different content is a conflict, not a successful duplicate. A genuine model retry has a new attempt ID. Enforce revision ordering with transactions/CAS where supported; a stale snapshot cannot overwrite a newer selected assessment. - -Append raw observations before deriving assessments in durable mode. If derivation fails, retain evidence for replay. A crash after provider acceptance but before a result can still leave unknown usage. Start intents and reconciliation expose that gap; they cannot guarantee the provider reports missing usage later. - -Repricing creates a new assessment. Default reports continue to use the original selected assessment until an explicit view change. Never rewrite history simply because the bundled catalog changed. Invoice adjustments must preserve their original currency, scope, and evidence. - -### Scale assumption - -Design initially for local SDK use and a shared service storing up to roughly one million attempts per month. This is a planning workload, not a measured Agentium limit. At an assumed 4 KB per compact attempt plus observations/assessment, base data is about 4 GB per month before indexes and stream evidence. Keep final/meaningful usage observations, not text chunks. Bound raw usage size. Indexed paging and incremental projections are sufficient first steps; no queue cluster or sharding is justified by current evidence. - -## 9. Budget behavior - -Use ledger totals and unsettled reservations, not an evictable display cache or delayed telemetry exporter. Keys include tenant, scope type, scope ID, period, and currency. - -Preserve run/session/user controls, and add explicit root-run or operation-tree scope for child work. Define time windows for cross-run budgets. Validate limits as finite nonnegative amounts; zero blocks charged work and is different from absent. - -Return a typed decision: allowed, warned, or blocked, with scope, limit, known spend, reserved amount, and unknown usage/cost status. Honor warn/stop/throw consistently. Emit a real typed budget event if documented; do not invent an error class only in docs. - -Two modes: - -- **Threshold mode:** checks known/estimated spend before new work and after observations. Can exceed the threshold because accepted requests continue and usage may arrive late. Default unknown policy: warn and continue, with explicit incomplete accounting. -- **Reservation mode:** atomic admission using conservative per-operation bounds. Requires an atomic `BudgetStore` and a valid bound on applicable charges. Default unknown policy: block before dispatch. If no bound exists, reject reservation mode for that operation or require an explicit configured bound. - -Reservation mode controls admission, not an unconditional provider invoice ceiling. Hidden provider work, changing contract terms, or unavailable usage can exceed estimates. Record overruns and uncertain reservations. Do not automatically release an expired reservation for an accepted request whose outcome is unknown; reconcile it or retain a conservative hold. `warn` does not stop execution. - -Reserve all applicable limits atomically, or roll back entirely. Settle actual known spend once, using the same attempt/reservation identity. A crash/retry cannot deduct twice. Budget projection correction needs an atomic delta if a selected assessment changes. Reporting-only repricing must not silently change budget balances. - -## 10. Compatibility and developer experience - -Keep `import { CostTracker } from "@agentium/core"` and `AgentConfig.costTracker`. The improved facade adds explicit asynchronous methods such as `recordUsage`, `queryUsage`, `queryCosts`, and `flush`; pure `calculateCharges` remains usable without an agent or database. - -Illustrative intended usage; names must be fixed in phase 1 before implementation: - -```ts -const tracker = new CostTracker({ - catalog: reviewedCatalog, - store: usageStore, - budget: budgetPolicy, -}); - -const agent = new Agent({ name: "assistant", model, costTracker: tracker }); -await agent.run("Explain the result", { sessionId: "s1", userId: "u1" }); -await tracker.flush(); -const costs = await tracker.queryCosts({ sessionId: "s1", view: "original" }); -// costs.total is null when incomplete; costs.knownSubtotal is still usable. -``` - -Provide custom-adapter examples that report all four token categories, actual context, and unsupported meters. Provide custom tariffs with explicit cache-read and cache-write prices. The calculator must work with a caller-supplied catalog and no network. - -### Migration decision - -**Execution update, 2026-10-08:** The user approved implementation, checks, documentation, and release, then explicitly selected version **4.5.0**. This supersedes the major-version recommendation below. The implemented read-path and token-semantics changes are documented in the 4.5 migration guide and changelog. The original design recommendation remains here as review history. - -Do not silently turn `track()` or `getSummary()` into promises. Do not silently change `cost: number` into a string or map unknown cost to zero to satisfy its old type. - -Introduce canonical records/async methods additively while the old path is explicitly deprecated. Switch the default behavior only in a documented major release, because unknown-cost handling and ambiguous legacy token semantics are observable changes. The existing coordinated release system already versions packages together; a separate package is unnecessary. - -At the major cutover: - -- Keep legacy method names synchronous for local compatibility. They are projections for known complete data, not durable queries. -- Legacy `track()` requires documented legacy usage semantics or an explicit adapter mapping. Ambiguous reasoning/cache/modality input raises a typed compatibility error; do not guess. -- Legacy numeric cost projections can return finite numbers for complete known costs. Unknown or partially priced results require the canonical query API and raise a typed incomplete-cost error in the old projection. -- `getEntries()` remains a bounded local snapshot. `getSummary()` must not claim durable all-time coverage; reject unsupported queries and document snapshot scope. Canonical async queries serve durable history. -- Internal execution uses canonical methods and preserves successful provider results when accounting is incomplete. It does not route through legacy projection errors. -- Legacy model-price overrides are migrated to explicit API/provider scope and separate cache categories. A `reasoningPer1k` field alone cannot prove independent reasoning billing. - -If a major release is not acceptable, ship the canonical engine behind an explicit opt-in and finish migration design before changing defaults. Do not weaken correctness to claim a patch-compatible full revamp. - -### Events and consumers - -Add explicit `usage.recorded`, `cost.assessed`, and `cost.budget.exceeded` events with stable IDs, revisions, scope, and completeness. Final naming belongs in the phase 1 contract. - -Keep legacy `cost.tracked` as a replacement run-total projection for complete known amounts during migration. Do not emit an unknown amount as zero. New events carry incomplete results, and observability must expose their status. Update the built-in consumers to deduplicate IDs/revisions and avoid reading both old and new events as independent spend. - -Parent spans can display inclusive totals while only selected payable attempt/group/period charges contribute to global spend. Allocations and parent summaries do not create more spend. Admin/eval/browser/observability must consume core results rather than calculate their own model prices. - -## 11. Ordered build phases - -### Phase 1 — Fix the contracts and build provider fixtures - -Files: `cost/{types,usage,measurements}.ts`, `models/types.ts`, adapter normalizers, `cost/__tests__/fixtures/`, `models/__tests__/usage-conformance.test.ts` (new), `cost/__tests__/usage.test.ts` (new), and public type fixtures. - -1. Define exact types, invariants, status unions, context provenance, and compatibility behavior from sections 5 and 10. Validate raw input with Zod. Define registered meter keys without closing the API to custom meters. -2. Add sanitized raw response/stream fixtures per API path. Include schema/SDK version and source reference. Use synthetic metadata where real captures are unavailable and label it. Never copy credentials or prompts from conversation history. -3. Implement pure provider normalizers. Preserve raw evidence. Fix Cohere nesting and Anthropic cache semantics. Give OpenAI Chat/Responses/Decisions distinct mappings. Treat cloud/gateway billers separately. -4. Add conformance checks for the complete adapter inventory below. No adapter is marked complete without fixtures. -5. Define desired legacy projections and pin them with public type fixtures. Do not replace existing live accounting until the new path is integrated. - -Initial regression fixtures: - -- OpenAI: input 19, output 16, reasoning 9, total 35. Canonical total stays 35, not 44. -- OpenAI: input 19, output 76, reasoning 64, total 95. Canonical total stays 95, not 159. -- OpenAI cache example: 15,000 inclusive input; 12,000 read; 2,000 write; 500 output. -- Anthropic: 1,000 ordinary + 12,000 read + 2,000 write; 500 output; mixed 5-minute/1-hour write buckets. -- Google: candidates and thoughts separate, cache read, reported total, modality details, tool-use fields, and any unexplained residual. -- Cohere: `usage.tokens` differs from `usage.billedUnits` and neither disappears. -- Missing counters, explicit zero, malformed/negative/unsafe counts, conflicting subsets, and unrecognized schema fields. - -**Verify:** `npx vitest run packages/core/src/models/__tests__/usage-conformance.test.ts packages/core/src/cost/__tests__/usage.test.ts` → all contract fixtures pass. -**Verify:** `npx tsc -p packages/core/tsconfig.json --noEmit --pretty false` → exit 0. - -### Phase 2 — Record attempts at the provider boundary - -Files: `cost/{accounting,context}.ts`, built-in provider request/retry paths, `models/{provider,fallback-provider,model-router}.ts`, `agent/{agent,llm-loop,reflection,run-context,execution-services}.ts`, and scoped direct-call sites. - -1. Add an explicit accounting context and common metered invocation primitive. Ensure shared provider instances are safe for concurrent tenants/runs. -2. Meter leaf requests, preserve actual identity, and define retry ownership per SDK. Retain existing cancellation/routing/tool behavior. Distinguish transport attempts from opaque invocations. -3. Capture usage before output validation. Preserve available usage on failed/incomplete responses, parsing errors, cancellation, and late hook/tool failures. -4. Introduce stream observations; unify snapshot/delta handling and finalization. Preserve the existing OpenAI tail behavior. -5. Route reflection, compression, context compaction, tool selection/summaries, memory and team/workflow calls through the same boundary. Tag each operation purpose. -6. Derive run outputs from distinct canonical attempts. Remove generic prompt+completion+reasoning reconstruction and final-run charging in the new path. Keep each raw usage record; do not retain only the final providerMetrics object. -7. Preserve source/child distinctions for handoffs, subagents, and background jobs. Parent totals must not create charges. - -Direct-call inventory to resolve, in addition to `agent/` and provider files: - -```text -compression/compression-manager.ts -context/context-compactor.ts -tools/tool-router.ts -memory/curator.ts -memory/stores/{summaries,graph-memory,entity-memory,user-profile, - learned-knowledge,user-facts,procedure-memory}.ts -graph/retriever.ts -team/team.ts -workflow/step-runner.ts -``` - -These paths are under `packages/core/src/`. Re-run the direct-call search and classify every remaining production match; either it uses the new context/boundary or it has an explicit unmetered/opaque capability explanation. - -**Verify:** `rg -n '\.(generate|stream)\(' packages/core/src/agent packages/core/src/memory packages/core/src/compression packages/core/src/context packages/core/src/tools packages/core/src/team packages/core/src/workflow packages/core/src/graph` → reviewed inventory with no unexplained bypass. -**Verify:** `npx vitest run packages/core/src/cost/__tests__/accounting-lifecycle.test.ts packages/core/src/events/__tests__/execution-observers.test.ts packages/core/src/agent packages/core/src/models` → all pass, including duplicate snapshots, final usage after finish, failed hooks, two retries plus fallback, and parallel tenant isolation. -**Verify:** `npx tsc -p packages/core/tsconfig.json --noEmit --pretty false` → exit 0. - -### Phase 3 — Build the catalog and charge calculator - -Files: `cost/{calculator,catalog,pricing}.ts`, `cost/catalog-data/`, new exact-arithmetic helper, focused cost tests, core dependency manifest if needed. - -1. Implement unit/block/band/fixed/adjustment rule variants and validation. Use exact arithmetic and one explicit rounding policy per applicable rule. Define request versus billing-group evaluation; do not apply a session minimum independently to each attempt. -2. Implement exact rule matching, scoped overrides, explicit aliases, effective dates, and required-context validation. Reject ambiguous matches. -3. Generate charges from measurements and the adapter's required-meter coverage. Make unknown rates/quantities visible. Include cache reads and writes in public examples. -4. Seed reviewed rules for the supported model/API combinations. Check current official provider contracts, including latest OpenAI modes and each major provider's cache rules. Support endpoints separately, including Decisions and cloud deployments. Do not call a model just to retrieve a price. -5. Preserve provider-reported costs with inclusion scope and provenance. Separate them from estimates and period adjustments. -6. Add catalog update validation and explicit version pinning. Remove fuzzy price matching and guessed cache discounts from the new engine. - -Required fixtures: the `0.072` four-category example; missing write price yields `total: null` and `knownSubtotal: 0.047`; explicit zero tariff; snapshot `o3-mini` never resolves to `o3`; ambiguous alias; Fast requested but Standard returned; Pro without double usage; missing tier; context threshold at/below/above boundary; mixed cache TTL; modality/cache intersection unknown; fixed search fee; duration rounding; unit mismatch; overlapping modifiers; stale/historical rates; custom account override; multiple currencies kept separate. - -**Verify:** `npx vitest run packages/core/src/cost/__tests__/calculator.test.ts packages/core/src/cost/__tests__/catalog.test.ts` → all pass with exact decimal string assertions. -**Verify:** `npx tsc -p packages/core/tsconfig.json --noEmit --pretty false` → exit 0. - -### Phase 4 — Add durable accounting and budgets - -Files: `cost/{store,budget,accounting,cost-tracker}.ts`, `cost/stores/`, scoped integration in Agent/run context and event definitions, focused storage/budget tests. - -1. Implement in-memory observation/revision/assessment stores and distinct totals independent of the display-entry cache. Define periods and retention. -2. Implement SQLite and Postgres stores with versioned schema migrations, unique keys, paged queries, and selected-assessment projections. Match existing optional SDK loading conventions. Do not force database setup for local users. -3. Prove idempotent duplicate delivery, conflicts on reused IDs with different data, monotonic revisions, and replay after derivation failure. Implement billing-group membership and revision selection; verify the two-20-second-observations fixture, late observations, and exact non-duplicating allocation views. -4. Implement typed threshold budgets for all scopes. Pass tenant/session/user/root-run context. Honor warning mode and zero limits. -5. Implement optional atomic reservations, transactional assessment-selection/settlement, uncertainty reconciliation, and concurrent admission tests. Reject strict/shared mode on a store without the required capability or when usage and budget interfaces use independent backends. Inject a crash between each conceptual settlement update; all updates must commit together or none may commit. -6. Inject store failures before submission and after provider response. Demonstrate that only accounting is retried after a successful provider operation. Preserve original execution errors. -7. Add explicit reprice/query views. Old assessments remain accessible; reporting repricing never changes spend twice. - -**Verify:** `npx vitest run packages/core/src/cost/__tests__/store.test.ts packages/core/src/cost/__tests__/budget.test.ts packages/core/src/cost/__tests__/accounting-lifecycle.test.ts` → all local tests pass, including >10,000 entries, zero/warn limits, replay, crash states, and uncertain usage. -**Verify:** a new `cost/__tests__/store.integration.test.ts` suite against disposable SQLite/Postgres stores must pass restart, migration, isolation, idempotency, and two-worker reservation races. Define an explicit test environment variable such as `AGENTIUM_COST_POSTGRES_TEST_URL` in the implementation; never run against a user's live database. This is a planned new harness, not an existing command guarantee. -**Verify:** `npx tsc -p packages/core/tsconfig.json --noEmit --pretty false` → exit 0. - -### Phase 5 — Extend coverage beyond ordinary model calls - -Files: usage-producing boundaries under `vector/embeddings`, `rerank`, `voice`, `vision`, `telephony`, `toolkits`, and the browser consumer. Cost rules remain under core cost modules. - -1. Add optional accounting context/sink to embedding and reranking calls. Keep their normal vector/result return shapes. Capture provider usage before discarding other response data. -2. Preserve realtime response IDs, modality/cache detail, event semantics, and terminal status. Settle per response/interval. Integrate STT/TTS character, duration, and token meters with source labels. -3. Capture image-generation usage plus model, size, quality, count, and any billed token quantities. Request count is an estimate until provider billing rules establish what was charged. -4. Provide a public custom-operation recording API for paid tools, search, sandbox compute, storage intervals, and external adapters. A tool execution alone is not proof of a particular fee. Accept namespaced meters and registered normalizers/calculators. -5. Inventory every built-in paid toolkit. Mark each as supported, partially supported, explicit free, or unmetered. Add provider-specific mappings when billing evidence exists. Unknown tools remain visibly uncovered; do not estimate from arbitrary wall time or text length. -6. Integrate BrowserAgent and native Voice/Vision through core accounting. Use proper run/operation IDs and the same budget policy. Parent processes consume core events, never duplicate price math. -7. Distinguish cache resource creation/storage duration from per-call cache reads. Background resource costs can have a resource/period parent instead of a model-call parent. - -**Verify:** `npx vitest run packages/core/src/cost/__tests__/operation-meters.test.ts packages/core/src/vector/embeddings packages/core/src/rerank packages/core/src/voice packages/core/src/vision packages/browser/src` → all applicable fixture suites pass with mocks/loopback fixtures and no live provider credentials. -**Verify:** `npm run build:core` followed by `npx tsc -p packages/browser/tsconfig.json --noEmit --pretty false` → exit 0. Build is a future implementation gate, not part of this review. - -### Phase 6 — Migrate consumers, documentation, and release contracts - -Files: core exports/README/compatibility facade, observability consumers/tests, relevant eval/admin consumers, docs pages below. No package extraction. - -1. Publish exact API names/types, async lifecycle, scope defaults, error policy, and coverage matrix. Keep sync APIs sync and clearly limited. Pin major-release migration decisions before default cutover. -2. Add call/assessment events and retain the run-total legacy event contract. Prove equal run totals without counting both event streams. Track completeness and unpriced counts in observability. -3. Replace incorrect test expectations with provider-contract fixtures. Keep old supported complete-cost consumers compiling and document expected errors for ambiguous/incomplete legacy inputs. -4. Update docs and generated references together. Explain input/read/write/output with real formulas, actual service tier, Pro behavior, context/cache TTL/modality rates, retries, failures, storage, and budget limits. -5. Remove unsupported claims of universal accuracy, nonexistent budget events/errors, and universal cross-agent auto-stop. State named provider/API/version coverage and limitations. -6. Run final package/type/fixture gates, review the public diff, and update `plans/README.md`. No release command is part of this plan's execution without separate authorization. - -Docs update set under `/Users/xerycks/Xhip/agentium-docs`: - -```text -cost/overview.mdx -features/cost-autostop.mdx -examples/cost-observability.mdx -api-reference/core/{cost,models,storage}.mdx -storage/overview.mdx -observability/{overview,exporters}.mdx -performance.mdx -``` - -Follow the docs repo's generation/check workflow; do not hand-edit generated references without updating their source. - -**Verify:** `npm run build` → all packages build. -**Verify:** `npm test` → all tests pass; any pre-existing failure must be identified separately. -**Verify:** `npm run test:package` → packed ESM/CommonJS/type consumers pass. -**Verify:** `npx biome ci .` → exit 0. -**Verify in docs repo:** `npm run check`, `npm run check:api`, `npm run check:examples`, `npm run check:imports`, and `npm run validate` → exit 0. These scripts exist in the reviewed docs manifest; their current baseline was not executed. - -## 12. Adapter acceptance matrix - -Every row needs non-stream, stream where supported, missing usage, cache behavior, identity, and failure coverage appropriate to its API. Shared code can share fixtures only when the billing contract actually matches. - -| Paths | Required distinctions | -|---|---| -| OpenAI Chat, Responses, Decisions | Inclusive output/reasoning; read/write; actual mode/tier; endpoint rules; failed/incomplete usage. | -| Azure OpenAI, Foundry | Deployment/resource mapping, biller, region, API schema; never price by deployment substring. | -| Anthropic, AWS Claude | Exclusive input; cache read/write and TTL; initial stream usage; inclusive output; hosted-tool meters where exposed. | -| Bedrock Converse | Metadata-after-stop; actual identity/region; cache details. | -| Google, Vertex | Candidates/thoughts, reported totals, modalities, cache, tool-use detail, metadata-only events. | -| DeepSeek, xAI, Meta/custom compatible | Versioned provider-specific billing mappings; unknown gateway pricing explicit. | -| Mistral, Perplexity, Cohere | Native versus compatible schemas; billed units and extra fees; late usage and duplicate terminal events. | -| Ollama, JEV | Explicit free versus missing price; retained duration/usage; exact model identity. | -| Vercel v0 adapter | v0 API contract; do not substitute Vercel AI SDK semantics merely because of the name. | -| Custom adapter | Normalizer/meter/context registration, partial capabilities, conformance helper, opaque retries. | - -Reference implementations to learn from, not copy blindly: - -- [Vercel AI SDK usage shape](https://github.com/vercel/ai/blob/main/packages/provider/src/language-model/v3/language-model-v3-usage.ts): cache-read/write distinctions and raw evidence. -- [T3 Code pricing implementation](https://github.com/pingdotgg/t3code/blob/main/apps/server/src/usage/usagePricing.ts): pure calculation and speed/category breakdown. Its documented approximations are unsuitable as silent default billing rules here. -- [Mastra pricing model](https://github.com/mastra-ai/mastra/blob/main/observability/mastra/src/metrics/pricing-model.ts) and [TokenCostControl](https://mastra.ai/reference/processors/token-cost-control): scoped policy and separation of pricing; async metric-based budgets have acknowledged lag. -- [OpenAI caching](https://developers.openai.com/api/docs/guides/prompt-caching), [Fast](https://developers.openai.com/api/docs/guides/fast-mode), [reasoning](https://developers.openai.com/api/docs/guides/reasoning), [Anthropic caching](https://platform.claude.com/docs/en/build-with-claude/prompt-caching), and [Google usage metadata](https://ai.google.dev/api/generate-content#UsageMetadata): provider-specific normalization evidence. Refresh at implementation time. - -## 13. Final acceptance criteria - -All of these must be demonstrated before the canonical path becomes the default: - -- [ ] The 19/16/9 OpenAI fixture produces 35 total tokens and one output charge. -- [ ] Every cache example includes separate read and write quantities/rates; TTL buckets never duplicate their total. -- [ ] Inclusive reasoning/audio/modality details cannot be charged twice. -- [ ] Missing usage/rates/context never become an apparently complete zero charge. -- [ ] Exact identity and explicit aliases replace substring guessing. -- [ ] Tier, context band, region, cache duration, API, effective time, and account overrides select reproducible rules. -- [ ] Every observable retry/fallback leaf has its own attempt; opaque retries are labelled. -- [ ] Failed hooks, tools, parsing, and cancellation retain completed/partial provider evidence. -- [ ] Repeated snapshots replace; unique deltas add; late usage and post-finish failure are handled. -- [ ] Auxiliary model calls and supported non-model operations appear in the operation tree. -- [ ] Parent totals equal their selected distinct charges or allocated shares, with matching completeness; group charges and their allocations are never both added. -- [ ] Session/account minimums and rounding occur once per billing group. Replay and late observations revise its selected assessment without duplicate spend. -- [ ] Durable replay and duplicate delivery do not duplicate charges or budget settlements. -- [ ] Eviction does not lower budget totals; durable restart preserves them; tenants remain isolated. -- [ ] Warning mode continues; zero limits are enforced; shared reservation races are atomic. -- [ ] Accounting failure after a successful provider call never triggers another provider call. -- [ ] Original assessments remain reproducible after a catalog update or repricing. -- [ ] Legacy events remain replacement run totals; canonical consumers do not double-read both streams. -- [ ] Public migration, capabilities, and docs match executed fixture results. -- [ ] No additional Agentium package or external accounting service was introduced. -- [ ] Phase commands and package checks have results recorded in the implementation review. - -## 14. Stop conditions and maintenance - -Stop and report a specific design conflict if: - -- Current source differs enough that the identified lifecycle or public API no longer exists. -- A provider contract contradicts the planned inclusive/exclusive mapping and cannot be resolved from authoritative documentation/fixtures. -- A supported SDK hides attempts and offers neither retry control nor a usable transport hook. Expose opaque visibility; do not invent attempts. -- A storage backend cannot guarantee capabilities advertised by the chosen budget mode. -- A legacy consumer requires unknown cost to remain zero or depends on double-counted totals. Use the documented major migration boundary rather than hiding the change. -- An implementation step needs unrelated model/tool behavior changes or a new external service. -- A verification failure cannot be explained after two focused correction attempts; preserve evidence instead of weakening the test. - -Reviewers should check normalization semantics before arithmetic, leaf identity before aggregates, and unknown coverage before totals. New provider features require a normalizer/capability update, pricing evidence, and fixtures. New billing units require an explicit meter and applicable rule, not another special case in the Agent loop. - -The weakest remaining part of this plan is external billing evidence for opaque/custom adapters and account-level contracts. Improve it by adding real sanitized provider fixtures and documented billable-unit mappings. Keep those combinations partial/unpriced until that work is complete. diff --git a/plans/2026-10-10-sdk-audit/README.md b/plans/2026-10-10-sdk-audit/README.md new file mode 100644 index 0000000..2f1d38f --- /dev/null +++ b/plans/2026-10-10-sdk-audit/README.md @@ -0,0 +1,485 @@ +# Agentium: staff engineer SDK and runtime audit + +**Verdict:** keep Agentium’s small model/tool contracts, ordinary Agent loop, neutral execution boundary, explicit harness composition, and core accounting. Its current implementation is a useful foundation, but its broad public surface and uneven state/lifecycle guarantees make production adoption substantially harder than the quickstart suggests. Repair those guarantees and narrow orchestration promises before adding capabilities. A new execution graph or universal plugin system would increase complexity without fixing the demonstrated problems. + +This audit started **2026-10-10** and completed **2026-10-11**, Asia/Kolkata. Repository baseline: **`c5f9b5249d299f5d2d39b74c87b83f0da7c15570`**. Root and all ten packages: **4.8.2**. Initial working tree was clean.

Research access dates are recorded in [research.md](research.md). Detailed priorities, reproduction outcomes, tradeoffs and verification limits are in [findings.md](findings.md). + +**Executed:** 446 selected existing tests passed, three report recipes typechecked and ran with local fakes, all 50 typed import paths loaded through ESM and CommonJS, consumer NodeNext type checks passed, four templates scaffolded/typechecked in temporary directories, and local fake probes demonstrated state, cancellation, persistence and delivery defects. Passing suites did not prevent those independent probes from finding failures. No dependency installation, live provider/database/hardware execution, paid call, publication, commit, or push occurred.

All 38 rules across api/types/err/cli/onboard/config were read; capability gates were applied rather than treating every missing flag as a defect. TypeScript, API/interface design, systematic debugging and the read-only improvement audit guidance informed the remaining review. The user’s requested S1–S4 ranking and three-report format take precedence over generic skill report templates. + +## What Agentium actually is + +Agentium is a Node-oriented TypeScript agent execution and integration SDK. Its central operation is an Agent’s model/tool loop, with shared contracts for messages, tools, run context, usage and observation. Team adds model-driven coordination recipes; Workflow adds stateful procedural steps; harness adds host-owned execution services, policy, resource lifetime and live conversation control. Separate transport/queue/admin/observability packages turn these runnables into application infrastructure. Core also exports independent memory, retrieval, protocols, realtime and durable-task facilities. The [published homepage](https://docs.agentium.in/) describes this composable SDK and optional packages, but the root export breadth makes the intended minimum harder to see. + +**Source-inspected:** `ModelProvider` is structural and does not require inheritance (`packages/core/src/models/provider.ts:4`). `ServableAgent` lets external runnables use transport without Agent (`packages/core/src/serve.ts:20`); `defineExternalAgent` wraps application functions (`packages/core/src/agent/external-agent.ts:9`). `ExecutionServices` is genuinely neutral: core consumes host model/tool/state/input operations and does not import or instantiate harness (`packages/core/src/agent/execution-services.ts:17`). Harness depends on core, not the reverse. That separation earns retention. + +The code in `packages/core/src/graph` is **knowledge-graph retrieval**: entities, relationships, traversal/search, semantic GraphMemory and raw Cypher retrieval (`packages/core/src/graph/types.ts:1`, `packages/core/src/graph/cypher-store.ts:5`). It is not an execution DAG. Workflow checkpoints and harness snapshots are not a durable execution engine. A separate durable task/action subsystem contains substantive fenced lease, intent, unknown-outcome and journal contracts (`packages/core/src/durable/README.md:39`, `:47`, `:69`); its production crash guarantees were not executed here. + +The implied audience is an application developer who wants a ready loop plus tools and optional operational integrations, then grows into platform ownership. The examples favor a constructor, model factory, and one `run`; the sixth-month contracts assume the host understands storage guarantees, tenancy, borrowed resources, effects, accounting coverage and live-versus-durable continuation. Agentium can serve that audience if these responsibilities become explicit and consistently enforced. It should not compete simultaneously as a complete hosted memory product, database, deployment platform, workflow service and omnichannel application builder. + +## Package and public API map + +All packages are 4.8.2. Every feature package declares core as a peer. There are no observed runtime feature-package dependency cycles; some integrations import one another only for types or optional adapters. Core has **two required dependencies** (Zod and zod-to-json-schema), plus **27 optional peers**. The installation issue is therefore primarily API/compatibility breadth, not proven mandatory provider dependency bloat. A workspace containing every peer cannot prove installation without peers. + +| Package | Root named symbols | Responsibility and boundary judgment | Manifest evidence | +|---|---:|---|---| +| `@agentium/core` | 740 | Agent, tools/models, Team/Workflow, sessions/storage/memory/retrieval, accounting, durable tasks, protocols, sandbox, tenancy/webhooks/realtime.

Star exports resolved. A named class counts once, even when both type and value. Aliases/re-exports count once **per import path**; class members, option fields, CLI commands, private declarations and package.json contents are excluded. Unique identities resolve to original declaration path/position/name. Wildcard expansion uses the current toolkit build targets, not every theoretically matchable string. + +There are **16 manifest export keys** including one wildcard and core/package.json, **50 concrete typed import paths**, **1,486 named symbol slots** (**607 runtime**, **879 type-only**) and **1,251 unique declaration identities**. This is a reproducible compatibility-surface measure, not a count of concepts/features or of documented/stable promises. Root counts above are included in those totals. Additional aggregates: core/toolkits 80, core/voice 103, core/telephony 35, harness/testing 1. Toolkit wildcard paths contribute 160 slots, including the redundant toolkits/index aggregate alias. + +Manifest exports support ESM `.js`/`.d.ts` and CJS `.cjs`/`.d.cts` (`packages/core/package.json:28`). All 50 paths loaded in both modes and typechecked from NodeNext `.ts` and `.cts` consumers, using installed peers and skipLibCheck. All 50 source/built named-symbol sets matched. This rechecks the previously repaired CJS declaration issue; it does not imply a fresh build, packed installation, missing-peer compatibility, or full library declaration checking. + +Documented classes/factories and explicit harness testing belong to supported public contracts. Core loop helpers/ledger internals, browser search parsers, and the toolkit wildcard’s base/catalog/index helpers are also publicly importable; their intended semver support tier is unresolved (`packages/core/src/index.ts:41`, `packages/browser/src/index.ts:1`, `tsdown.config.ts:12`). Calling them “accidental” is an engineering judgment, not proven maintainer intent. Publish that intent before removing exports. + +Existing raw dist bytes: core 3,963,497; harness 442,951; transport 407,896; browser 312,424; observability 203,592; edge 176,432; eval 108,520; admin 96,224; queue 64,122; CLI 26,124. These include distribution files and declarations, not compressed npm archives, install trees or bundled applications. No tree-shaking or cold-start measurement was executed. Core declares sideEffects false (`packages/core/package.json:80`) despite module-level model-registry population; runtime publication and tree-shaker behavior need a dedicated characterization before changing that declaration. + +### Exhaustive manifest dependency/export inventory + +The following inventory covers every package manifest export and required/peer dependency, including ranges and optional status. Development dependencies are build/test tooling rather than published runtime dependencies; they are inventoried below but excluded from runtime dependency direction.

The implementation gives a quick useful result once credentials/installed tooling are present; production cost often appears when ownership, persistence, retries and provider escape matter. Eight journeys below show application code in actual 4.8.2 shapes. Snippets use named application dependencies where indicated; only specifically labelled cases were executed. Proposed APIs live in findings and are marked hypothetical. + +### 1. Minimal agent, provider swap, native options + +**Executed equivalent with a source fake; source-inspected public API.** This fake allows deterministic local adoption without credentials: + +```ts +import { Agent, type ModelProvider } from "@agentium/core"; + +const fake: ModelProvider = { + providerId: "local-fake", modelId: "fixture", + async generate() { + return { + message: { role: "assistant", content: "4" }, + usage: { promptTokens: 1, completionTokens: 1, totalTokens: 2 }, + finishReason: "stop", raw: {}, + }; + }, + async *stream() { + yield { type: "text", text: "4" }; + yield { type: "finish", finishReason: "stop", + usage: { promptTokens: 1, completionTokens: 1, totalTokens: 2 } }; + }, +}; +const agent = new Agent({ name: "math", model: fake, register: false }); +try { console.log((await agent.run("2+2?")).text); } +finally { await agent.close(); } +``` + +Swapping to `openai(modelId)` or `anthropic(modelId)` keeps Agent code small; provider factories and credentials must be configured explicitly. `providerOptions:{serviceTier:"priority"}` reaches one OpenAI knob today (`packages/core/src/models/types.ts:161`). Neither service calls nor capability equivalence were executed. Provider-native client/fetch injection is missing in these adapters: [F13](findings.md#f13--add-typed-provider-owned-native-escape-hatches). + +First hour: two methods to fake, one constructor/run/close, low boilerplate; easy text/tool portability. Sixth month: application owns credential rotation/native capability choice, while Agentium should own consistent retry/cancel/usage boundaries. A provider swap cannot erase opaque replay requirements or decision-vs-chat differences. Jev/OpenAI Decisions are verified question/decision providers, with specialized fields leaking into shared request/output types; capability discrimination earns more than pretending universal portability. + +### 2. Tools, stream, cancellation, retries and thrown work + +**Source-inspected; fake throw/abort/cap/retry probes executed.** `defineTool` infers args from Zod 3/4 Classic/Mini schemas (`packages/core/src/tools/schema.ts:17`, `packages/core/src/tools/define-tool.ts:5`). Application lookup is host-owned: + +```ts +import { defineTool, Agent } from "@agentium/core"; +import { z } from "zod"; +const lookup = defineTool({ + name: "lookup", description: "Read an application record", + parameters: z.object({ id: z.string() }), + execute: async ({ id }, ctx) => { + ctx.signal?.throwIfAborted(); + return JSON.stringify(await applicationLookup(id, ctx.signal)); + }, +}); +const abort = new AbortController(); +const agent = new Agent({ name: "reader", model, tools: [lookup], + register: false, retry: { maxRetries: 2 }, maxToolRoundtrips: 3 }); +try { + for await (const chunk of agent.stream("Read record 42", { signal: abort.signal })) { + if (chunk.type === "text") process.stdout.write(chunk.text); + } +} finally { await agent.close(); } +``` + +First hour: typed args and model-visible tool failures are convenient. SDK turns thrown tools into result errors; the application must check terminal outcome and await iterator exhaustion. Sixth month: application owns effect idempotency and cooperative cancellation inside its dependencies; SDK should prevent post-abort dispatch, exact cap overruns and incomplete events. Current run/stream retry behavior diverges and Agent does not expose ToolExecutor’s concurrency option ([F01](findings.md#f01--share-cancellation-retry-and-tool-cap-invariants), A04–A07). Five parallel tools by default may be wrong for a mutable business resource. Native provider SDK retry ownership must be explicit to predict latency/cost. + +### 3. Bring an execution loop/driver; human input and steering + +**Source-inspected custom-driver recipe; selected conversational suites executed.** A driver can use the runtime’s services without implementing the full host: + +```ts +import { HarnessRuntime, type ExecutionDriver } from "@agentium/harness"; +const driver: ExecutionDriver = { + id: "application", version: 1, + capabilities: { controls: [], durable: false, + policyCoverage: "local", controlledExecution: true }, + async start(request, services) { + const reply = await services.requestInput({ question: "Which account?", choices: ["A", "B"] }); + services.append([ + { role: "user", content: request.input }, + { role: "assistant", content: String(reply.input) }, + ]); + return { text: String(reply.input) }; + }, +}; +const runtime = new HarnessRuntime({ driver, grants: { toolIds: [], modelRoles: [] } }); +const handle = runtime.start("Choose account", { + identity: { tenantId: verifiedTenant, userId: verifiedActor }, sessionId: "s", +}); +for await (const event of handle.events()) { + if (event.payload.type === "input.requested") await handle.reply(event.payload.request.id, "A"); +} +const result = await handle.result(); +``` + +`verifiedTenant/verifiedActor` come from host authentication. Agent driver advertises steering controls; the minimal custom driver above advertises none. Send only modes the chosen driver supports, e.g. `handle.send(text,{mode:"steer"})` for an appropriate adapter. RunHandle input is live, correlated and distinct from tool approval (`packages/harness/src/runtime/driver.ts:133`). One pending question, input-wait versus active deadlines, FIFO steering after a settled batch and final-call races have focused tests (`packages/harness/src/__tests__/conversational-runs.test.ts:195`). + +First hour: driver capabilities, identity, grants and event/result handles introduce more concepts than plain Agent. Sixth month: explicit authority and resource ownership earn them. Arbitrary SDK calls inside a trusted driver bypass runtime budgets/policy/telemetry; use `services.model/streamModel/dispatch/runOwned`. A host implementing ExecutionServices itself faces roughly twenty members, so split optional subports only when actual adapters demonstrate need. For existing application loops, `defineExternalAgent({name,register:false,run:applicationRun})` is simpler, with lifecycle issues in A04. Persisted history does not resurrect suspended closures; async write acknowledgment still needs [F06](findings.md#f06--await-harness-session-commit-and-release). + +### 4. Team, Workflow, Harness or plain TypeScript + +**Source-inspected; Workflow/Team fake probes executed.** For two deterministic calls, ordinary code is the best baseline: + +```ts +const draft = await writer.run(input, { signal, ephemeral: true }); +const review = await reviewer.run(draft.text, { signal, ephemeral: true }); +return review; +``` + +Use Workflow when step records/conditions/state browsing are worth a step API: + +```ts +import { Workflow } from "@agentium/core"; +const workflow = new Workflow({ name: "review", register: false, + initialState: { input, text: "" }, + steps: [{ name: "draft", run: async state => ({ text: (await writer.run(state.input)).text }) }], +}); +const result = await workflow.run(); // inspect stepResults, including errors +``` + +Use Team for deliberate model-selected coordination, not merely Promise.all. Its prompt orchestration introduces coordinator cost, member session suffixes and mode-specific outcomes. Native Team handoff is currently blocked and configuration promises drift ([F10](findings.md#f10--give-handoff-one-lifecycle-owner)). Use Harness when the host must centrally control grants, models, budgets, human input, context and completion revisions. It should be an opt-in environment around a loop rather than a prerequisite for calling models. + +First hour: four overlapping names lack a crisp selection ladder; start with Agent/plain functions. Sixth month: dependency failure policy and state ownership matter more than syntax. Workflow today collects errors and continues; it is not equivalent to awaited functions or a durable engine. Repair patch/replay contracts and make failure policy explicit ([F04](findings.md#f04--merge-workflow-branch-writes-not-copied-input), [F05](findings.md#f05--preserve-checkpoint-cursor-identity-across-replay), A02). If resumable waits/versioned recovery are essential, adapt an external durable engine or the existing qualified task supervisor. Do not add an execution graph just to fix these bugs. + +### 5. Sessions, memory and knowledge with custom stores + +**Source-inspected API; fake store/reconstruction probes executed.** KV storage needs get/set/delete/list/close, optional initialize. Vector and graph stores have separate contracts; one “store” does not imply all guarantees. + +```ts +import { MemoryManager, KnowledgeBase } from "@agentium/core"; +const memory = new MemoryManager({ storage: hostStore, userFacts: true, summaries: false }); +await memory.getOrCreateSession("s", "u"); +await memory.remember("User prefers TypeScript", { userId: "u" }); +const facts = await memory.recall("TypeScript", { userId: "u" }); + +const knowledge = new KnowledgeBase({ name: "docs", vectorStore: hostVectorStore }); +await knowledge.add({ id: "guide", content: applicationDocument }); +const hits = await knowledge.search(question); +const result = await agent.run(JSON.stringify({ question, facts, documents: hits })); +``` + +These names are core exports; stores/documents are application dependencies. Choose one memory owner: the standalone manager above, or Agent’s `memory:{storage,...}`; do not accidentally create two session owners. Host scopes storage to authenticated identities and defines authority/retention. Agent opts `sessionId/userId/tenantId` do not automatically namespace arbitrary stores. Automatic extraction can make model calls; this recipe does not claim extraction is free/deterministic. + +First hour: explicit userFacts matters—default remember can succeed without storing anything. Sixth month: ordinary managers need atomic mutation/recovery, a versioned identity codec, complete listing, and drain ownership ([F02](findings.md#f02--encode-storage-tuples-without-collisions), [F03](findings.md#f03--define-atomic-session-mutation-and-recovery-capabilities), [F11](findings.md#f11--drain-all-owned-memory-work-before-closing-its-store)). Persistent vector data does not persist KnowledgeBase BM25 ([F12](findings.md#f12--give-lexical-retrieval-a-corpus-lifecycle)). Harness canonical history and Agent backing sessions/search_past_sessions are explicitly different (`packages/harness/README.md:109`), a real concept cost. Escape through external history/ephemeral runs and application-owned retrieval tools is useful and should stay. + +### 6. Deterministically evaluate the application’s own agent + +**Executed real Agent plus fake ModelProvider: one case passed, no provider calls.** Reuse the fake from journey 1: + +```ts +import { EvalSuite, contains } from "@agentium/eval"; +const applicationAgent = new Agent({ name: "evaluation", model: fake, register: false }); +try { + const result = await new EvalSuite({ + name: "application", agent: applicationAgent, + cases: [{ name: "addition", input: "2+2?", expected: "4" }], + scorers: [contains("4")], + }).run(); +} finally { await applicationAgent.close(); } +``` + +First hour: two packages, familiar case/scorer structure, tiny deterministic fake. Sixth month: shared memory/effects still need fixture isolation; scripted model judges/users are deterministic, provider-backed ones are not. Current EvalSuite requires concrete Agent even though execution needs run; a structural wrapper was rejected by the public TypeScript consumer ([F14](findings.md#f14--evaluate-an-application-target-without-adopting-agent)). Retain strict score/deadline/result integrity rather than replace eval wholesale. An application may use promptfoo/Evalite/Braintrust instead; Agentium outputs should be easy to project into those systems. + +### 7. Account for cost, inspect it and enforce budgets + +**Source-inspected recipe; synthetic tariff/ledger and 105 accounting tests executed.** + +```ts +import { CostTracker, Agent } from "@agentium/core"; +const costs = new CostTracker({ budget: { + mode: "threshold", onExceeded: "throw", onUnknown: "block", + limits: [{ scope: "session", amount: "2", currency: "USD", + period: { start: "2026-10-01T00:00:00Z", end: "2026-11-01T00:00:00Z" } }], +} }); +const agent = new Agent({ name: "metered", model, costTracker: costs, register: false }); +try { + const result = await agent.run(input, { tenantId, sessionId }); + console.log(result.costs?.total, result.costs?.knownSubtotal); + console.log(await costs.queryCosts({ tenantId, sessionId })); +} finally { + await agent.close(); // borrowed tracker remains host-owned + await costs.close(); +} +``` + +For simplest accounting, `cost:true` owns a tracker and result snapshot. Unknown pricing produces null total and known subtotal, not zero spend (`packages/core/README.md:186`). A fake/custom model needs an explicit catalog to price its synthetic usage; unknown-block policy is intentionally conservative. Threshold admission may overshoot while a call runs; strict reservation needs atomic shared accounting and a conservative per-attempt bound (`packages/core/README.md:232`). Neither guarantees an invoice. + +First hour: opt-in accounting is now clear, unlike older manual tracking. Sixth month: host owns scope attribution, catalog versions, actual billing facts and shared-store guarantees. Core tracks observable physical attempts/auxiliary work and separates usage evidence from assessment. Direct native calls outside the wrapper remain outside its coverage. Legacy synchronous budget APIs still silently disagree with canonical totals ([F08](findings.md#f08--reject-incompatible-synchronous-budget-reads)); move to scoped async reads. Retain cost in core as previously decided. + +### 8. Scaffold locally and add a skill + +**Executed local built CLI, temporary scaffold and local-skill validation.** + +```sh +# Executed from a temporary cwd; no install or model run followed. +node /Users/xerycks/Xhip/agentium/packages/cli/dist/bin.js init basic --template basic +node /Users/xerycks/Xhip/agentium/packages/cli/dist/bin.js skills install ./skills/example +``` + +The local folder must contain SKILL.md. Installation validates it, then tells the host to register explicitly (`packages/cli/src/commands/skills.ts:6`). Application configuration uses `skillDirs:[approvedSkillDirectory]`; AgentConfig also accepts loaded Skill objects/sources (`packages/core/src/agent/types.ts:41`, `:115`). An npm/Git source invokes npm install with scripts disabled; not executed here. No unified plugin discovery/install runtime is implied. + +First hour: all basic/RAG/voice/browser templates scaffolded and typechecked using existing dependencies. Basic closes its Agent and requires OPENAI_MODEL; RAG actually supplies retrieved evidence; voice makes media transport ownership explicit (`packages/cli/src/commands/new.ts:23`). Config-only voice startup worked. Sixth month: CLI should stay a thin local utility, use installed tooling predictably, and print actionable errors. Invalid template/name/destination/skill errors include internal stacks; dev invokes npx despite an installed-tool requirement (A09). Publish is a convenience npm wrapper, not an Agentium deployment model. No reason to build a larger CLI framework before fixing those small contracts. + +## Coherent extension contracts, with boundaries + +Agentium has multiple extension points, **not one unified plugin system**. Standardization earns its cost where it preserves authority and continuation; merging every callback into a plugin would hide meaningful distinctions. + +| Extension | What it should own | Current assessment / smallest useful improvement | +|---|---|---| +| ModelProvider/embedders | native request adaptation, normalized responses/usage; independent vector encoding | Keep structural ports; typed native options/client injection and conformance tests. Do not equate chat and decision capability. | +| ToolDef/toolkits/skills | callable capability/schema/result; bundles and source instructions | Keep schema inference, raw JSON-schema bridge for MCP. Support other schemas only through a validated conversion adapter, not universal inference claims. | +| Agent hooks/loop hooks | local lifecycle and prompt/response adaptation | Useful lightweight escape; state allowed transformations and error semantics. Do not use observer events for mandatory decisions. | +| Guardrails/execution policy/approval | validation versus authority and human approval | Keep distinct. Mandatory policy must not be replaceable by hooks or tool exemption; missing approval fails closed. | +| Harness abilities/middleware | pure definition then run binding, ordered transforms/observation | Keep lifecycle separation and ordering validation (`packages/harness/README.md:150`). Avoid another automatic registry. | +| Controller/context/completion policies | choose next model/tools; project context; accept/revise output | Distinct roles earn complexity. controlModel avoids recursive policy calls and shares budgets (`packages/harness/src/runtime/driver.ts:658`). Document selection ladder and one owner per concern. | +| Driver/ExecutionServices | execution strategy versus host authority, state and work lifetime | Keep core-neutral boundary; capability honesty and optional subports only for demonstrated hosts. | +| EventBus/observability/webhooks | observations and delivery diagnostics | Keep isolation/observation-only. Repair adapter promise/event ownership, not mandatory async bus dispatch. | +| Storage/session/vector/graph/accounting stores | domain persistence guarantees, atomicity, corpus lifetime | Retain separate small ports; add optional domain capabilities and versioned codecs rather than a universal database interface. | + +### State, concurrency and operational ownership + +Agent creates run-local loop/executor state (`packages/core/src/agent/agent.ts:475`), a strength for simultaneous runs. Tool batches settle started work before parent failure/control transfer (`packages/core/src/tools/tool-executor.ts:181`); approvals snapshot reviewed args and fail on mutation (`:265`) or missing required approval (`:299`). These are more valuable than maximal pluggability. App code owns transaction/idempotency semantics for external effects; Agentium must own its own caps, cancellation, transcript pairing and terminal observation. + +Team combines member/coordinator state and mode-specific prompts; some options are unused or incompletely forwarded. Workflow owns procedural state but promises less than a durable workflow engine; today its merge/replay contracts are incorrect. Harness owns canonical conversations, session leases, run resources and budgets; Agent adapter uses ephemeral history to avoid duplicate persistence (`packages/harness/README.md:53`). Session, extraction, vector corpus, pricing ledger and live turn all have different lifetimes; treating them as one “memory” or “storage” misleads adopters. + +Durable tasks already model unknown external outcomes and reconciliation rather than promise exactly-once arbitrary effects (`packages/core/src/durable/README.md:49`, `:51`). Keep this qualified contract; pair it with explicit deployment/store/reconciler ownership. Transport, queues and protocols should route/delegate without claiming remote local-policy coverage. Telephony’s authorization/fetch/timeouts and intent-store pattern are useful precedents for narrower integrations. Voice/browser are specialized loops with different authorities; forcing them under one universal Agent would lose clarity. + +### Implicit behavior inventory + +These are **source-inspected**, not all executed against external adapters: + +| Behavior | Trigger / owner | Evidence and implication | +|---|---|---| +| Entity publication | Agent/Team/Workflow construction unless register:false | `packages/core/src/agent/agent.ts:470`; global replacement/discovery, F15. Close does not remove publication. | +| Built-in model factory population | Model registry module evaluation | `packages/core/src/models/registry.ts:51`; shared mutable factory table and any-typed config. Explicit instance injection avoids it. | +| Shared observers/log | EventBus.shared opt-in; default SSE event log module object | `packages/core/src/events/event-bus.ts:29`, `packages/transport/src/sse-event-log.ts:103`; Agent normally has its own bus. Specify scope/retention rather than assume every event is global. | +| Provider environment/client state | OpenAI construction or first call without key | `packages/core/src/models/providers/openai.ts:23`, `:41`, `:55`; SDK require, OPENAI_API_KEY fallback, per-key client cache capped at 50. Environment/client lifetime can outlive one request. Other providers were sampled, not exhaustively traced here. | +| Storage initialization | MemoryManager construction | `packages/core/src/memory/memory-manager.ts:52`; initialize may open host resources before first run. Async lifetime must be owned. | +| Feature defaults/work | Memory sessions/summaries default; optional facts/learnings; run background extraction | `packages/core/src/memory/memory-manager.ts:56`, `:60`, `:362`; absent remember destination and work drain differ, F11/A01. Model-backed work is not a free read. | +| Files/skills/context | Explicit Agent skillDirs/contextFiles/workspace feature configuration | `packages/core/src/agent/types.ts:41`, `:46`; discovery/filesystem work belongs to enabled initialization, not pure harness define/describe. Avoid network-backed skill sources without explicit deployment policy. | +| Hidden retry/counting defaults | Generic retry and provider SDK layers; plain tool cap | `packages/core/src/utils/retry.ts:8`; three generic retries with jitter/backoff, SDK behavior separate. F01 calls for one owner and exact effect boundaries. | +| Toolkit discovery/build surface | Explicit factory catalog; build enumerates toolkit .ts files | `tsdown.config.ts:12`; wildcard exports broaden whenever files are added. No unified plugin runtime is implied. | + +## Recommended structure + +**Compatible first:** retain all existing packages and root aliases. Define a small primary core surface: Agent, ModelProvider/messages, tools, RunContext/result, execution policy, sessions and cost opt-in. Add intentional advanced subpaths such as execution/testing, storage, retrieval, durable and protocol adapters, with an explicit support tier. Accounting stays in core. Existing voice/telephony/toolkit separation is directionally sound. Reject arbitrary new root exports in review until a use case and compatibility commitment are clear. + +**Then narrow:** Team should contain a few distinct coordination recipes with explicit outcomes; remove redundant handoff after migration. Workflow should remain optional lightweight procedural composition/debugging, with patch/cursor/failure guarantees. Harness remains a host environment and lifecycle layer around replaceable drivers. Simplify default docs to Agent → plain functions → choose one additional abstraction based on a concrete need. + +**Only split physical packages when operational differences justify it:** provider/native adapters, protocols, carrier/realtime/sandbox dependencies are optional integrations; subpaths may suffice given today’s small mandatory footprint. Keep transport, queue, observability, browser and Edge optional. Admin becomes an injected control-plane adapter, not the global SDK owner. Do not create a separate cost package against the examined prior decision or merge core and harness merely to shorten imports. A physical split adds coordinated releases/peer matrices and may yield less than a supported subpath. + +```mermaid +flowchart TD + APP[Application: identity, data, effects, deployment] --> HOST[Optional Harness or application host] + APP --> CORE[Core Agent and small contracts] + HOST --> PORT[ExecutionServices] + CORE --> PORT + CORE --> MODEL[Replaceable model adapters] + CORE --> TOOL[Tools and policy] + CORE --> DATA[Session and retrieval capabilities] + CORE --> COST[Core usage and accounting] + INFRA[Optional transport, queue, observability, admin] --> RUN[Structural runnable] + CORE --> RUN + APP --> RUN + DUR[Optional durable supervisor or external engine] --> RUN +``` + +The diagram shows contract relationships, not a claim that all arrows provide durability or policy interception.

Breaking changes need customer use evidence, not cosmetic symmetry. | +| Later evidence-driven integrations | Adapter to existing durable engine when deployment needs recoverable waits/versioning; memory service integration when corpus/quality/operations warrant it. | Failure/reconciliation/restart tests with explicit external service ownership. Do not market ordinary runs as durable. | + +Maintainer work should focus on a reusable transition/invariant test layer rather than immediately rewriting the two large run/stream loops. Add a provider through the structural port first; first-party support additionally requires native option types, registry/export updates, usage/replay mapping and conformance tests. Adding an event needs payload compatibility, identity, one start/terminal pairing and no authority change. Existing tests often pin happy-path status without values, or mock a protocol the real Agent no longer uses; real-contract composition tests offer higher leverage than more isolated mocks. + +## Prior decisions and release cost + +Prior plans were read before source: `plans/README.md`, core-cost accounting and DX reviews/implementation, catalog verification and conversational-run plans. **Keep cost in core:** accounting is an execution invariant; optional adapters/subpaths are enough. **Keep EventBus observation-only:** direct admission/accounting writes own control; isolated observers should not rerun providers. F07 is an adapter discarding promises, not evidence against that decision. Previously repaired CJS declarations passed fresh consumer probes. Prior unpriced/usage/reasoning issues are not repeated as current defects. + +Local changelog/tags show intentional v3 removals/toolkit isolation and v4 harness migration (`CHANGELOG.md:79`); v4.5 documented canonical accounting migration (`CHANGELOG.md:40`); later 4.7/4.8 embedder additions and 4.8.1/4.8.2 service-tier widening. Release frequency alone is not evidence of instability. Removing Agent.deep and requiring explicit defaults/grants is real migration work, justified by ownership/authority clarity (`packages/harness/README.md:55`). v4.5 preserved some signatures but made synchronous accounting reads throw; that is real runtime migration cost and exposes F08’s remaining inconsistency. A semver-preserved TypeScript signature does not guarantee behavior compatibility. + +The public docs homepage was read; some attempted markdown/document fetches were unavailable to the research tool. That is a research limitation, not proof the website is broken or universally stale. Local Edge README failure is independently executed. Benchmarks are historical provider-backed comparisons, not current reliability/performance proof; details in research. + +## If building Agentium today + +**Keep:** a small structural model contract, inferred tools with authority separate from validation, an ordinary bounded Agent loop, normalized public/opaque messages, run-local state and settled effects, core opt-in accounting with explicit unknowns, structural runnable integrations, and optional harness abilities/resources/control. Keep durable action reconciliation’s honesty and eval integrity checks. + +**Design differently:** explicit host publication, one retry/cancel/terminal invariant layer, domain storage guarantees and codecs, patch-based Workflow state/versioned cursors, structural evaluation target, provider-owned native customization, bounded asynchronous memory lifetime and lexical corpus ownership. Use fewer Team recipes and a smaller documented primary surface. Make each enabled capability observable and each unsupported option actionable. + +**Refuse to build without demonstrated demand:** another general execution graph/durable service, a universal plugin registry spanning tools/policies/observers/drivers, automatic global discovery, a hosted memory/control-plane product inside core, invoice/exactly-once promises, automatic process supervisor or telephony/browser deployment stack, and a CLI framework whose main job is wrapping npm. Prefer ordinary application code or mature optional infrastructure when it owns the necessary operational contract better. + +The goal is a trustworthy small center with useful integrations. The current center earns investment; expanding its perimeter before resolving these boundaries does not. diff --git a/plans/2026-10-10-sdk-audit/findings.md b/plans/2026-10-10-sdk-audit/findings.md new file mode 100644 index 0000000..29965fc --- /dev/null +++ b/plans/2026-10-10-sdk-audit/findings.md @@ -0,0 +1,332 @@ +# Agentium SDK audit — findings + +Audit started **2026-10-10**; completed **2026-10-11**, Asia/Kolkata.

Agent made **two requests, one after abort**, and returned `status:"completed"`. Generic retry checks neither signal nor abortable backoff (`packages/core/src/utils/retry.ts:34`, `:38`, `:46`); LLMLoop invokes it without a cancellation boundary (`packages/core/src/agent/llm-loop.ts:209`). The nonstream final-answer branch has no post-call abort check (`:419`), whereas Agent streaming checks before completion (`packages/core/src/agent/agent.ts:1357`). A custom provider remains responsible for stopping an already running external operation, but the framework owns preventing another dispatch after known cancellation. + +A second fake probe configured `maxToolRoundtrips:0`: plain Agent executed **one tool**, then stopped. Both loops use `roundtrip <= maxToolRoundtrips` (`llm-loop.ts:339`, `:637`); the actual pre-tool claim exists only for controlled execution (`:267`). A final answer call after N tool batches is useful; another effect batch is not. The controlled-loop tests cover zero and one, leaving plain-path parity unpinned (`packages/core/src/agent/__tests__/controlled-loop.test.ts:53`). A fake streamed 429 with `retry.maxRetries:2` was invoked once: stream uses `streamObserved` directly (`llm-loop.ts:684`), unlike generate. + +**Impact:** cancellation can be reported as success and configured effect limits can be exceeded. Real billing after abort was not tested. Built-in adapters often forward/check cancellation, which reduces exposure but does not repair the structural-provider escape path. + +**Recommendation:** implement common pre-dispatch, post-response, and pre-tool-batch checks; abortable retry waits; validate nonnegative integer limits. Allow the final model answer while rejecting excess tools. Choose one retry owner and state physical-attempt limits. Provider-private retries and SDK retries currently add layers (`packages/core/src/models/providers/openai.ts:31`, `packages/core/src/models/providers/anthropic.ts:61`); their multiplied request counts are **source-inspected hypotheses**, not measured here. OpenAI Decisions explicitly disables SDK retries (`packages/core/src/models/providers/openai-decisions.ts:84`). Stream retry should apply only before public commitment; fallback already refuses swapping after a public chunk (`packages/core/src/models/fallback-provider.ts:97`). + +**Strongest retention case:** cooperative cancellation and separate run/stream implementations keep adapters flexible; inclusive iteration enables a final answer. Preserve those benefits while centralizing the invariants. This is a targeted repair, not grounds to rewrite Agent into an execution graph. **Migration:** mostly corrective behavior; code relying on N+1 batches or successful post-abort output changes. Add ordinary/controlled/run/stream matrix tests, abort during backoff and final response, and physical-attempt assertions with fake adapters. + +## F02 — Encode storage tuples without collisions + +**Defect; executed and source-inspected.** Distinct scopes `{tenantId:"a",userId:"b"}` and `{tenantId:"a:user:b"}` mapped to the same namespace; the second read the first fixture. Scope strings are unrestricted, while `ScopedStorage` concatenates components with `:` (`packages/core/src/storage/scoped.ts:24`). InMemoryStorage separately flattens `(namespace,key)` the same way (`packages/core/src/storage/in-memory.ts:6`): `set("parent:child","key",value)` is readable through `get("parent","child:key")`; `list("parent")` includes the child namespace (`:24`). Redis uses the same raw key format and raw SCAN pattern (`packages/core/src/storage/redis.ts:44`); Redis effects were not executed. TenantScopedStorage repeats raw tenant namespacing (`packages/core/src/tenant/tenant-storage.ts:13`). + +**Impact:** cross-scope read/overwrite and namespace enumeration contamination are demonstrated at the public storage layer. Exposure through an authenticated HTTP endpoint was not tested. Tenancy helpers are not authorization, but that does not excuse their isolation codec being non-injective. + +**Recommendation:** use a versioned, injective tuple codec, preserving absent versus empty components; store namespaces separately in memory; encode literal Redis prefixes/globs. Harness already uses `JSON.stringify([tenantId,userId,sessionId])` for its key (`packages/harness/src/runtime/session-bindings.ts:29`), a useful local precedent. Test delimiters, Unicode, empty IDs, glob metacharacters, and exact namespace listing. Add ownership-aware scope wrappers: `ScopedStorage.close()` currently closes the shared inner driver (`scoped.ts:52`). + +**Strongest retention case:** common UUIDs/slugs avoid collisions, readable keys help operations, and persistent migration is expensive. These public types permit arbitrary strings and the fix adds little machinery; readability can live in metadata. **Migration:** never silently fall back to ambiguous old keys. Persistent adapters need an explicit migration using trusted tenant/key mappings, collision detection, and a cutoff. Some old key tuples cannot be reconstructed uniquely. Keep this release concern separate from host authentication. No recommendation to add mandatory accounting transactions to generic StorageDriver. + +## F03 — Define atomic session mutation and recovery capabilities + +**Defect; executed and source-inspected.** Two SessionManager instances sharing JSON-cloning InMemoryStorage appended A and B concurrently. Both calls succeeded; history contained only B. Locks belong to each manager (`packages/core/src/session/session-manager.ts:20`, `:29`); append is read/modify/write (`:73`). Generic StorageDriver has no atomic append/CAS (`packages/core/src/storage/driver.ts:1`). This occurs in one process with two managers, not only distributed deployments. + +An IncrementalSessionManager fake persisted a message, then failed its metadata write. That message was readable. Recreating the manager and appending replaced it with the new message. Sequence reconstruction consults metadata/snapshot rather than the loose log (`packages/core/src/session/incremental-session-manager.ts:82`); loose entries precede metadata writes (`:150`). Existing incremental tests cover snapshot cleanup failure, a different boundary (`packages/core/src/session/__tests__/incremental-session.test.ts:18`). + +**Impact:** accepted conversation data can disappear; storage persistence alone does not provide session mutation safety. Hosts can enforce one owner externally, but the current interface cannot express or verify that guarantee. + +**Recommendation:** repair loose-log high-water recovery immediately; then add an optional SessionStore capability for atomic append, expected revision, and idempotent message IDs. Preserve generic KV for features that need only KV. Explicitly advertise process-local versus distributed single-writer guarantees and reject requested guarantees the store cannot supply. High-water recovery alone does not solve concurrent writers. + +**Before — current contract:** + +```ts +const left = new SessionManager(store); +const right = new SessionManager(store); +await Promise.all([ + left.appendMessage("s", { role: "user", content: "A" }), + right.appendMessage("s", { role: "user", content: "B" }), +]); // both fulfill; one accepted message remains in the probe +``` + +**After — hypothetical optional contract:** + +```ts +await sessions.append({ + scope: { tenantId, userId, sessionId: "s" }, + expectedRevision, + messages: [{ id: applicationMessageId, role: "user", content: "A" }], +}); // acknowledged atomic revision, or a typed conflict +``` + +**Strongest retention case:** tiny KV adapters and per-instance locks make simple usage cheap; mandatory database transactions would raise every integration’s cost. Optional domain capabilities retain that benefit. **Migration:** opt-in adapter adoption is additive; requiring stronger defaults later needs a major release. Define session codec/version recovery and test two independent managers, ambiguous retries, and failure after every write. Session durability remains distinct from durable execution. + +## F04 — Merge Workflow branch writes, not copied input + +**Defect; executed and source-inspected.** Starting at `{a:0,b:0}`, parallel branches returning `{a:1}` and `{b:2}` produced **`{a:0,b:2}`** with all steps marked done. Each branch receives copied full state (`packages/core/src/workflow/step-runner.ts:218`); entire branch states are merged (`:225`), so B’s untouched `a:0` erases A’s update. Existing parallel tests start with empty state and assert statuses rather than merged values (`packages/core/src/workflow/__tests__/workflow.test.ts:247`, `:254`). Nested input references are also shared by the shallow copies; mutation isolation is source-inspected, not exercised by this probe. + +**Impact:** a common typed-state workflow silently loses results. Declaration order makes the loss deterministic, not valid. + +**Before — current application code:** + +```ts +new Workflow({ + name: "both", register: false, initialState: { a: 0, b: 0 }, + steps: [{ name: "updates", parallel: [ + { name: "a", run: async () => ({ a: 1 }) }, + { name: "b", run: async () => ({ b: 2 }) }, + ] }], +}); +``` + +**After — hypothetical explicit merge policy:** + +```ts +parallel({ steps: [updateA, updateB], merge: "disjoint" }); +// merge only produced patches; competing writes require a reducer +``` + +**Recommendation:** first fix internals while preserving existing step APIs: carry branch patches separately from branch state. Define collision policy, default to rejecting ambiguous writes or require a reducer; clone/freeze inputs if immutability is promised. Avoid a new graph DSL just to repair this merge. + +**Strongest retention case:** whole-state results make nested sequential steps convenient and permit declaration-order overwrite. Keep whole state for serial execution; unchanged copied fields are not deliberate competing writes. **Migration:** disjoint updates become correct without application changes; define compatibility behavior for intentional conflicts. Test initialized state, nested branches, conflicting keys, rejected branches, and mutation. A successful build cannot validate this semantic contract. + +## F05 — Preserve checkpoint cursor identity across replay + +**Defect; executed and source-inspected.** A workflow incrementing by 1, 10, 100 ended at 111. First replay also ended at 111, but its generated checkpoints stored B at index 0 and C at index 1. Replaying the B checkpoint yielded **121**, repeating B. Replay slices remaining steps (`packages/core/src/workflow/workflow.ts:252`), restarts indices at zero (`:183`, `:195`), then interprets them against the original definition (`:221`). Tests cover one replay (`packages/core/src/workflow/__tests__/checkpoints.test.ts:48`). + +**Impact:** incorrect state is demonstrated; repeated emails/payments/tool effects are a **hypothetical consequence** if application steps contain such effects. Checkpoints do not make those effects reversible or exactly once. + +**Recommendation:** persist absolute step positions or stable definition-bound step IDs and validate workflow/definition version on load. `workflowName` is saved but not validated by replay (`workflow.ts:194`, `:219`). Preserve identity, cancellation, policy, and relevant request options through checkpoint APIs: `runWithCheckpoints` accepts only session/user (`:139`) and replay constructs a minimal new context (`:247`). Document snapshots as debugging/re-execution, with later effects rerun. Use the durable subsystem or an external engine when recovery rather than exploratory replay is required. + +**Strongest retention case:** inexpensive snapshots/forks are useful and should not acquire a service dependency or durable execution semantics. The recommendation keeps them while repairing their own cursor contract. **Migration:** new checkpoints are straightforward; old checkpoints created during replay have ambiguous original position and need validation/rejection or a trusted definition-specific mapping. Do not infer position merely from nonunique names. Test replay-of-replay, forks, changed definitions, wrong workflows, and context propagation. No rewrite is justified by this defect. + +## F06 — Await harness session commit and release + +**Defect at an extension boundary; executed and source-inspected.** A fake custom store advertised durable/distributed ownership and delayed `lease.commit`. Harness returned completed success with **`persisted:false, released:true`**; persistence happened later. The public lease declares `commit`/`release` returning void (`packages/harness/src/runtime/session-bindings.ts:14`), while the store advertises durable/CAS/distributed guarantees (`:25`). TypeScript permits an async function where a void callback is expected. Runtime commits without await and sets `committed=true` (`packages/harness/src/runtime/driver.ts:1037`), and likewise ignores completion during partial commit/release (`:1064`, `:1083`). + +**Impact:** remote persistence acknowledgment is not part of terminal success or writer ownership. Remote failure/data loss and a second writer entering too early are **hypothetical**; premature acknowledgment/release is executed. Synchronous in-memory store behavior is unaffected. + +**Recommendation:** make commit/release `void | Promise`, await them in every path, and order terminal success after write acknowledgment. Surface failed partial persistence and release diagnostics while preserving the original execution error. Test held/rejected commits, asynchronous release, cancellation during commit, and cleanup precedence. + +**Strongest retention case:** the runtime deliberately supports live in-process continuation and a simple store; making all operations remote increases burden. Awaiting optional promises retains synchronous adapters. Durable conversation data is distinct from reviving a suspended driver; this fix does not require durable harness execution. **Migration:** additive types and stronger acknowledgment timing; implementations currently returning rejected promises will finally surface failures. Check latency expectations and close semantics rather than requiring a new storage product. + +## F07 — Own webhook forwarding work and retain unsent events + +**Defect; executed and source-inspected.** With a fake failed delivery and `onError:"throw"`, the probe observed an **unhandled rejection** and zero EventBus observer failures. The listener starts forwarding without returning its promise (`packages/core/src/webhooks/webhook-manager.ts:53`). With two batch records and the first failing, only the first was attempted; another flush had no records. Flush clears the full batch before delivery (`:96`) and exits on the first thrown failure (`:104`). A detach/awaited-flush timer rearm race is source-inspected (`:82`), not reproduced. + +**Impact:** destination incidents can lose never-attempted events and escape process rejection handling. This is the webhook adapter’s work ownership defect. EventBus correctly isolates returned observer promises; the prior observation-only decision remains sound. + +**Recommendation:** explicitly own/observe forwarding promises, preserve unacknowledged records, serialize flush/stop, and expose delivery/drain diagnostics. Return the promise to EventBus when appropriate, or catch/report it in the adapter. A bounded best-effort queue is sufficient for observation; add a durable outbox only for applications explicitly requiring delivery guarantees. + +**Strongest retention case:** analytics/webhooks should not block model execution; durable delivery machinery would be disproportionate. The targeted repair maintains observation-only semantics while preventing avoidable rejection and loss. **Migration:** low, but specify retry duplication and shutdown timeout behavior. Test throw mode, partial batches, enqueue during flush, stop during delivery, and noncooperative sinks. Existing webhook tests cover successful/filter/retry/batch/manual-flush paths (`packages/core/src/webhooks/__tests__/webhook-manager.test.ts:19`, `:97`), not these failure boundaries. + +## F08 — Reject incompatible synchronous budget reads + +**Defect in compatibility methods; executed and source-inspected.** A canonical fixture record totaling `"0.072"` with `maxCostPerRun:0.05` produced: `queryCosts.total="0.072"`, async scoped `checkBudget` blocked, yet `estimateRemaining("run-1")` returned **0.05 remaining**, `isBudgetExceeded` returned false, and string `checkBudget("run-1")` did not block. Those synchronous methods read only legacy totals (`packages/core/src/cost/cost-tracker.ts:230`, `:375`, `:405`). Canonical usage is separately recorded. `getEntries` already rejects this incompatible state (`:418`). + +**Impact:** adopters maintaining old dashboards/manual preflight enforcement can misreport headroom or miss an exceeded budget. This does **not** demonstrate failure of normal Agent canonical admission: the scoped decision correctly blocked in the same probe, and 105 selected accounting tests passed. + +**Recommendation:** apply the documented canonical/legacy incompatibility guard to every synchronous total/budget method; add async scoped remaining/status queries backed by the ledger. Deprecation alone is insufficient when results silently look valid. Keep compatibility methods for purely legacy local data if needed. + +**Strongest retention case:** signatures were preserved to ease v4.5 migration, and old manual tracking can still work. Refusing incomplete answers matches the existing release decision better than inventing zero spend. **Migration:** some old code will newly throw; provide a migration example and typed error pointing to async scoped APIs. Test all legacy reads after `recordUsage`, including mixed histories. + +**Prior decision explicitly examined:** retain accounting in core. Attempts, admission, usage normalization, finalization and nested scopes touch execution invariants (`packages/core/src/cost/accounting.ts:117`, `packages/core/src/cost/context.ts:26`). A separate mandatory cost package would create more bypass opportunities; optional pricing/catalog/store adapters or subpaths are enough. Threshold budgets intentionally may overshoot on an admitted call; reservation mode requires a defensible bound (`packages/core/src/cost/budget.ts:75`, `packages/core/README.md:232`). That tradeoff is documented, not a new defect. Unknown cost remains null rather than zero; snapshots are not provider invoices. + +## F09 — Retrieval must not inherit arbitrary write authority + +**Defect conditional on database permissions; executed dispatch, source-inspected backend.** A fake model generated `MATCH (n) WITH n LIMIT 1 DETACH DELETE n`. GraphRAGRetriever handed it **unchanged** to the fake store. The prompt says “prefer” MATCH over write (`packages/core/src/graph/retriever.ts:22`); a LIMIT regex is the only local transformation (`:37`); generated text directly reaches `runCypher` (`:76`, `:85`). Neo4jCypherStore opens a normal session and executes it with the caller’s principal (`packages/core/src/graph/cypher-store.ts:75`). No database mutation or external exploit was executed. + +**Impact:** retrieval is exposed to destructive/provider-generated queries when the principal can write. A preexisting LIMIT also bypasses the configured bound; a comment/string/earlier LIMIT is not an output cap. The `graph` subsystem is a knowledge graph, not an execution graph (`packages/core/src/graph/cypher-store.ts:5`, `packages/core/src/graph/types.ts:1`). + +**Recommendation:** separate trusted raw Cypher operations from a retrieval-only authority. Require a read-only database principal; offer parameterized supported read operations or a rigorously parsed query policy restricting writes, procedures/admin commands and multiple statements. Enforce output/time limits outside generated text. Parser checks supplement actual permissions; READ access mode is routing and not a security guarantee, as the [Neo4j JavaScript manual](https://neo4j.com/docs/javascript-manual/current/transactions/) explains. + +**Strongest retention case:** arbitrary schema queries are the feature and hosts already own credentials; fully constraining Cypher reduces usefulness. Keep raw CypherStore for trusted application code and an explicit advanced escape, but do not silently give a Retriever that authority. **Migration:** provide read-adapter/permission verification guidance and deprecate permissive defaults. Test generated deletes, unsafe procedures, misleading LIMITs, oversized results and permission errors. The observed dispatch warrants S1 conditional on a write-capable store; actual destructive database behavior remains unverified. + +## F10 — Give handoff one lifecycle owner + +**Defect; executed and source-inspected.** A real Agent using exported `createHandoffTool`, a real specialist with fake model, and `TeamMode.Handoff` failed with **`Handoff requested without configured targets`**, specialist calls zero. Team expects `member.run()` to reject with HandoffSignal (`packages/core/src/team/team.ts:321`). ToolExecutor now catches it as out-of-band settled control (`packages/core/src/tools/tool-executor.ts:364`); Agent consumes that control and requires its own configured targets (`packages/core/src/agent/agent.ts:901`). Team’s test mocks an obsolete thrown `run()` protocol (`packages/core/src/team/__tests__/team.test.ts:417`). + +**Impact:** the advertised native Team handoff journey is blocked. Supplying Agent targets moves delegation into Agent, so Team’s transfer chain/limits cease to be its owner. + +**Recommendation:** deprecate TeamMode.Handoff and favor Agent handoff or a harness driver owning routing. Retain it only if a shared explicit transfer outcome gives one owner transcript, identity, policy, settlement and limits. Do not restore thrown early transfers that abandon sibling effect settlement. Narrow Team to distinct, tested prompt orchestration recipes rather than promise every coordination style. + +**Strongest retention case:** a team router conveniently coordinates independently configured members. It deserves a public abstraction if its semantics differ usefully from Agent delegation; the current protocol does not meet that threshold. **Migration:** medium; explain moving targets/limits and write a real Agent+tool+Team integration test before deprecation. Direct Agent handoff can remain. + +**Related Team drift, separately characterized:** `memory` promises shared member memory (`packages/core/src/team/types.ts:30`), but Team consumes neither memory nor storage; TeamFactory even scopes then passes unused memory (`packages/core/src/agent/factory.ts:68`). That is source-inspected S2, not an executed tenant leak. Remove/deprecate unused settings before implicitly mutating borrowed Agents. Collaboration exhaustion passes empty member responses to synthesis (`team.ts:282`), executed with a fake coordinator. Buffered `Team.stream` awaits run (`:126`); coordinator generation drops run options (`:378`) and member options omit some accepted fields (`:367`). These need recipe-specific tests and accurately narrowed contracts; they do not justify a general graph rewrite. + +## F11 — Drain all owned memory work before closing its store + +**Lifecycle defect; executed drain symptom, source-inspected shutdown.** Holding the fake overflow-summary model open, `awaitExtractions()` returned with zero summaries; releasing the model later persisted one. Overflow summary is untracked (`packages/core/src/memory/memory-manager.ts:169`), while afterRun extraction has pending-operation tracking (`:362`) and drain watches only that set (`:428`). Agent starts background extraction (`packages/core/src/agent/agent.ts:973`) but closes storage without first draining it (`:560`). The API advertises graceful-shutdown use of drain (`memory-manager.ts:419`). + +**Impact:** the application lacks a dependable completion boundary for its own asynchronous persistence. Immediate process exit or store shutdown may lose work; that loss was **not executed**. Best-effort extraction and fast run responses are valid choices. + +**Recommendation:** one operation owner for summaries/extraction; bounded drain with diagnostics; Agent.close drains owned work before closing owned storage. Specify borrowed storage behavior and freshness opt-in. Keep normal run latency independent of extraction and keep observers informational. Noncooperative callbacks require timeout/cancel diagnostics, not indefinite shutdown waits. + +**Strongest retention case:** extraction is explicitly best effort and mandatory synchronous extraction would make every request slower or close hang. A bounded explicit lifecycle preserves low latency. **Migration:** close may wait longer; document limits and provide host-owned storage/drain options. Test held/rejected summaries and extraction, close during work, and borrowed shared drivers. A separate queue-backed MemoryWriter can be optional; do not build durable orchestration into MemoryManager by default. + +## F12 — Give lexical retrieval a corpus lifecycle + +**Defect/contract gap; executed and source-inspected.** Using the same surviving fake vector collection, keyword search returned one document before KnowledgeBase recreation and zero after; vector search still returned one. Each object allocates a fresh BM25 (`packages/core/src/knowledge/knowledge-base.ts:78`); initialize initializes only the vector store (`:81`); only that object’s additions populate BM25 (`:87`). VectorStore lacks a hydration/enumeration contract (`packages/core/src/vector/types.ts:1`). Hybrid ranking consequently loses its lexical component silently. + +**Impact:** restarting a worker or constructing another wrapper changes retrieval semantics despite persistent documents. Default vector retrieval still works; this is not evidence that all knowledge ingestion or retrieval fails. + +**Recommendation:** an optional lexical search port, native hybrid backend, or persisted document journal with explicit rebuild/readiness. If dependency-free BM25 stays, label it local/ephemeral and expose completeness. Do not add mandatory enumeration to every vector backend or re-embed persistent documents merely to rebuild lexical state. + +**Strongest retention case:** local BM25 is cheap and useful for short-lived corpora, and it avoids a search service dependency. Keep that mode explicitly; persistent search must see a corpus independent of one object’s write history. **Migration:** vector-only consumers unaffected; persistent hybrid consumers choose a lexical backend/rebuild strategy. Test restart, shared wrappers, out-of-band ingestion, deletion, and score-quality consistency; similarity/throughput benchmarks alone miss corpus lifecycle. + +## F13 — Add typed provider-owned native escape hatches + +**Architectural tradeoff; source-inspected; integration burden is judgment.** ModelProvider is a small structural contract (`packages/core/src/models/provider.ts:4`), but shared ProviderOptions is a flat catalog of OpenAI/Anthropic/Gemini knobs (`packages/core/src/models/types.ts:161`). Built-in OpenAI accepts only key/baseURL and constructs its SDK (`packages/core/src/models/providers/openai.ts:10`, `:31`); Anthropic similarly creates its own client (`packages/core/src/models/providers/anthropic.ts:22`). An adopter needing custom transport, SDK middleware, headers or an unmodeled native feature must provide a custom adapter and own normalization for the additional native behavior. Existing adapters can be composed/delegated; a complete source fork is not necessary in every case. Public custom model factory configuration is `any` (`packages/core/src/models/registry.ts:29`). Telephony’s injected fetch/auth/timeout is a better existing integration precedent (`packages/core/src/telephony/types.ts:98`). + +**Before — supported shared knobs:** + +```ts +new Agent({ name: "bot", model: openai(modelId), + providerOptions: { serviceTier: "priority" } }); +// a missing native knob/client option requires a custom ModelProvider today +``` + +**After — hypothetical additive adapter API:** + +```ts +const model = openai(modelId, { + client: applicationOwnedClient, + nativeOptions: { /* adapter-specific, SDK-typed request settings */ }, +}); +``` + +**Recommendation:** keep portable messages/tools/basic options and normalized usage; add typed provider-scoped options and owned/borrowed client/transport injection. Prevent overriding framework-owned tools/model/signal, validate capability support, and meter the same adapter invocation. Provider-native calls made elsewhere remain host accounting responsibility. Use a provider conformance suite rather than claiming all native features are portable. + +**Strongest retention case:** normalization makes swapping easy and limits surprising provider behavior. The bounded native extension makes that portability boundary more honest. **Migration:** additive initially; gradually deprecate flat provider-only fields with adapter-specific replacements, preserve returned billing facts and opaque replay envelopes. + +**Jev/Decisions verified:** these are question/decision providers (`packages/core/src/models/providers/jev.ts:28`, `packages/core/src/models/registry.ts:175`), not ordinary chat models. Their questions/decisions appear in general ModelConfig/RunOpts/RunOutput (`models/types.ts:234`, `agent/types.ts:241`, `:252`). OpenAI Decisions rejects tools and chat knobs (`models/providers/openai-decisions.ts:95`). Add explicit decision capability/operation; do not force incompatible accounting systems or pretend tools are supported. + +## F14 — Evaluate an application target without adopting Agent + +**Integration defect; executed public type check and source-inspected.** A real source Agent with fake model passed one deterministic EvalSuite case. A structural application `{run(input,opts):Promise}` was rejected by public declarations with TS2740: it lacks Agent internals and many unrelated members. `EvalSuiteConfig.agent` requires Agent (`packages/eval/src/types.ts:50`); CaseLifecycle calls only `.run` for execution (`packages/eval/src/case-lifecycle.ts:103`). Its own integrity tests cast fake Agents (`packages/eval/src/__tests__/result-integrity.test.ts:23`). + +**Impact:** custom loops, harness applications and composition wrappers need a cast or concrete Agent wrapper just to evaluate application behavior. This weakens a useful standalone package. The current rich RunOutput/scorer contract can remain Agentium-specific. + +**Before:** + +```ts +new EvalSuite({ name: "app", agent, cases, scorers }); +// `agent` must be the concrete Agent type +``` + +**After — hypothetical minimal compatible extension:** + +```ts +interface EvalTarget { + run(input: MessageContent, opts?: RunOpts): Promise; +} +const target: EvalTarget = { run: applicationRun }; +new EvalSuite({ name: "app", agent: target, cases, scorers }); +``` + +**Recommendation:** accept a structural target (or `Pick`) first. A generic task callback with arbitrary outputs can be considered later; it is not necessary to unblock common composition. Retain per-case deadlines, session reservation until noncooperative callbacks settle, invalid-score rejection, and infrastructure/execution distinctions. These are unusually valuable tested guarantees (`result-integrity.test.ts:123`). + +**Strongest retention case:** Agent provides session/tool/usage-aware evaluation semantics and cancellation metadata. Keeping RunOpts/RunOutput preserves those without requiring the class. **Migration:** additive and small; update WeakMap typing and strengthen consumer type tests. Do not require users to rebuild an eval framework or introduce another agent factory to make a fake. + +## F15 — Make publication an explicit host operation + +**Architectural tradeoff; source-inspected.** Agent/Team/Workflow constructors register by default (`packages/core/src/agent/agent.ts:470`, `packages/core/src/team/team.ts:40`, `packages/core/src/workflow/workflow.ts:35`). The global registry exposes maps and silently replaces same-name entities (`packages/core/src/serve.ts:71`); Agent.close does not unregister (`agent.ts:560`). Transport can inject a registry or disable it (`packages/transport/src/express/router-factory.ts:147`, `packages/transport/src/socketio/gateway.ts:34`), while admin EntityFactory hardcodes global entity/model registries (`packages/admin/src/entity-factory.ts:2`, `:59`, `:110`). + +**Impact:** construction changes routing/discovery outside the object, same-name instances change ownership, and closed/ephemeral instances can remain discoverable. Actual endpoint exposure through a particular application was not tested. `register:false` already provides a useful local escape, but integrations use it inconsistently. + +**Before:** + +```ts +const agent = new Agent({ name: "bot", model }); // global publication +``` + +**After — hypothetical host API:** + +```ts +const agent = new Agent({ name: "bot", model, register: false }); +const registration = host.register(agent); // explicit collision policy +await registration.close(); // removes only this owned registration +``` + +**Recommendation:** add injected registries to factories/admin, ownership-aware handles, and explicit replacement policy. Offer concise `host.serve(agent)` for discovery; change the constructor default only in a major release. Keep model factory registration separate from publishing runnable instances. Document module-level built-in model registrations (`packages/core/src/models/registry.ts:51`) and the default shared SSE log (`packages/transport/src/sse-event-log.ts:103`). + +**Strongest retention case:** automatic discovery materially improves the first hour and allows one-line servers. Explicit host publication retains that convenience with local lifetime control. **Migration:** additive host API first, deprecation warnings/docs next, default change later. Tests must cover duplicate names, two hosts, replacement ownership, close, and construction without publication. Do not replace this with a universal global plugin registry. + +## Additional findings and architectural tradeoffs + +These were investigated but do not merit fifteen additional full redesigns.

[Loop control](https://ai-sdk.dev/docs/agents/loop-control). + +Illustrative application contrast: + +```ts +// Agentium 4.8.2 +const result = await new Agent({ name: "reader", model, tools: [lookup], + register: false, maxToolRoundtrips: 3 }).run(question); + +// AI SDK API shape: explicit loop policy over a tool map +const result = await generateText({ model, prompt: question, + tools: { lookup }, stopWhen: stepCountIs(3) }); +``` + +These limits do not necessarily count the same thing: compare model steps, effect batches and final-answer opportunity before migrating. Agentium’s controlled and plain caps already differ (F01). **Lesson:** name and test the counting boundary; keep a manual call/loop escape. **Poor fit:** replacing Agentium’s qualified accounting, approvals and execution services with a text-call convenience would drop important semantics; adopting every AI SDK UI/provider abstraction also changes scope. + +OpenAI adapter configuration exposes custom fetch and provider-native settings, demonstrating that normalized calls and native transport customization can coexist. [OpenAI provider](https://ai-sdk.dev/providers/ai-sdk-providers/openai). **Lesson:** add an application-owned client/fetch and provider-scoped native options to Agentium while protecting model/tools/signal and usage normalization. It is not necessary to copy its entire provider matrix or invent universal capability equivalence. + +### OpenAI Agents JS: separate configuration, runner and session + +Runner makes loop ownership explicit, with turn limits, streaming, run state, context, cancellation and tool-error behavior. Sessions separately manage history; MemorySession is local, and application session implementations are possible. Provider conversation IDs and local history are different strategies. [Running agents](https://openai.github.io/openai-agents-js/guides/running-agents/), [sessions](https://openai.github.io/openai-agents-js/guides/sessions/). + +```ts +// Illustrative ownership difference +const result = await runner.run(agentDefinition, input, { session, signal }); +// Agentium: agent.run(input, { sessionId, signal }); backing owner lives on Agent +``` + +**Lesson:** document execution owner and history owner separately; a reusable runner is useful when configuration should outlive run state. Agentium already constructs run-local loops, so separation can be achieved through contracts/docs without replacing its class. State persistence and resumable tool pauses require explicit records and boundaries, not just saving a conversation. + +Custom models/providers are documented escape hatches. [Models](https://openai.github.io/openai-agents-js/guides/models/). The official SDK guide states that the application hosts its tools/state/approval flow. [SDK deployment responsibility](https://developers.openai.com/api/docs/guides/agents/sdk#build-with-the-sdk). **Poor fit:** OpenAI-centric tool/Responses/handoff conventions are not a universal model protocol. Agentium should retain normalized minimum fields and preserve native opaque continuations rather than force those conventions onto Jev, Decisions, realtime or every chat provider. + +### Claude Agent SDK: a specialized runtime boundary + +The SDK runs the Claude Code runtime process with built-in tools, permissions, hooks and session behavior; its plugin system packages Claude-specific skills/agents/hooks/MCP configuration. That is substantially more than a model adapter and is not a drop-in replacement for an in-process neutral Agent loop. [Official overview](https://code.claude.com/docs/en/agent-sdk/overview). + +**Lesson:** represent runtime capability/authority honestly. Wrapping this through a structural runnable or explicit harness driver is more coherent than pretending its tools are locally intercepted Agentium effects. **Poor fit:** adopting its automatic workspace/plugin conventions and process permissions as the default for every Agentium application. Agentium’s pure definitions, explicit host grants and separate filesystem ownership are strengths; retain them. + +## Procedural orchestration, graph state and durable recovery + +### Plain TypeScript remains a serious competitor + +For serial business logic, `await draft(); await review();` gives clear exception propagation, application-owned state and no framework migration. This is an engineering judgment, not an external feature claim. Agentium Workflow earns its abstraction only when step metadata, branching, state operations or checkpoint browsing pay for it. Team earns its abstraction only when a model-selected coordination recipe is preferable to deterministic code. + +### Mastra: typed dataflow and explicit suspend/resume + +The workflow recipe supplies step input/output/resume schemas, explicit suspend, stored run snapshots and resume targeting a step. The typed resume payload teaches more than a generic callback returning unknown state. [Suspend and resume](https://mastra.ai/docs/workflows/suspend-and-resume). + +**Lesson:** make paused input and resumption a contract, not a convention. Agentium live harness questions already have correlated IDs and lifecycle tests; preserve that. **Poor fit:** importing an entire workflow/storage/application framework just to fix Workflow’s parallel patch loss. Documented snapshot persistence does not by itself establish per-effect exactly-once behavior; this research did not run Mastra recovery. + +### LangGraph.js: state update algebra and persistence are part of execution + +Checkpointers store thread execution state; stores support cross-thread data. Memory implementations remain process-local. That distinction prevents “I have a store” from implying recoverable execution. [Persistence](https://docs.langchain.com/oss/javascript/langgraph/persistence). Fault-tolerance documentation describes retry, timeout and error-handler sequencing, including version requirements. [Fault tolerance](https://docs.langchain.com/oss/javascript/langgraph/fault-tolerance). + +```ts +// Illustrative API boundary: thread checkpoint owner is explicit +const graph = builder.compile({ checkpointer, store }); +await graph.invoke(input, { configurable: { thread_id: applicationThreadId } }); +``` + +**Lesson:** explicit state merge/reducer semantics, definition identity and persistence ownership. A copied full branch state is not a valid patch merge (F04). Execution retry must have a clear relation to effects and error handling. **Poor fit:** requiring a node/edge/state DSL for an ordinary tool loop or two function calls; coupling all Agentium memory to execution thread state. Knowledge graphs and execution graphs solve different problems. No reason to rename Agentium’s graph retrieval package into a workflow feature. + +### Temporal: durable execution is a deployment contract + +Temporal replay checks generated commands against event history; workers and a service jointly own progress. That is materially different from a state snapshot plus rerunning arbitrary TypeScript. [Workflow execution/replay](https://docs.temporal.io/workflow-execution). TS child-workflow APIs make start acknowledgment and parent lifetime explicit. [Child workflows](https://docs.temporal.io/develop/typescript/workflows/child-workflows). + +**Lesson:** durability requires recorded operation identity, replay/version discipline, acknowledgment, time/wait semantics and separate effect handling. Agentium’s durable supervisor already acknowledges unknown outcomes and reconciliation; an optional Temporal adapter could host coarse agent operations for applications that need it. **Poor fit:** adding Temporal service/worker/replay restrictions to the first-hour Agent path, or treating an activity retry as exactly-once email/payment. This audit did not execute a Temporal worker or inspect every activity retry/version contract; adapter design needs a pinned follow-up test. + +### Inngest: stable step identity and saved results + +step.run persists successful step results and skips completed work on replay; stable step IDs and idempotent effects remain important. The best-practice guide emphasizes putting side effects inside steps because handlers can rerun. [step.run](https://www.inngest.com/docs/durable-execution/primitives/step-run), [best practices](https://www.inngest.com/docs/durable-execution/best-practices). + +```ts +// Illustrative host-owned durable boundary, not Agentium's current Workflow API +const draft = await step.run("draft-v1", () => createDraft(input)); +await step.run("deliver-v1", () => deliverIdempotently(draft, businessId)); +``` + +**Lesson:** preserve stable cursor/definition identity and separate completed results from effect outcomes. F05 needs an absolute cursor immediately; meaningful durable resume requires more than that fix. **Poor fit:** making event/service deployment a mandatory SDK concern. Optional integration is justified when recoverable waits, cross-worker retries and scheduling are actual application needs. + +### Decision for Agentium + +Do not build another general durable graph engine now. Repair Workflow as lightweight procedural composition/debugging and Harness as in-process controlled execution. Keep the separate durable task/action subsystem qualified. Add explicit adapters to an external engine when a real deployment requires it. No candidate removes application idempotency, versioning or operational ownership for free. + +## Memory and retrieval: a corpus is not one object’s write history + +### Mem0: narrow semantic memory operation, configurable backends + +The OSS Node recipe adds messages with user metadata and searches with filters, separately configuring LLM, embedder and vector store. Its default path can involve model/embedding work even though the application code is short. [Node SDK quickstart](https://docs.mem0.ai/open-source/node-quickstart). + +```ts +// Illustrative memory-only boundary +await memory.add(conversation, { userId: verifiedUser }); +const matches = await memory.search(question, { filters: { user_id: verifiedUser } }); +``` + +**Lesson:** a small external MemoryWriter/MemoryReader port can replace automatic Agentium extraction without replacing its loop. Make enabled targets, scope, spend, completion and deletion observable; do not let remember fulfill with no destination (A01). **Poor fit:** silently enabling semantic extraction/provider calls to make that method “work,” or copying another SDK’s defaults as safe production guarantees. Quality, tenant filtering and durable corpus behavior were not benchmarked. + +### Letta: explicit always-present memory blocks + +Memory blocks are managed independently and attached/detached to agents; shared blocks can be separate from retrieval. [Attaching and detaching blocks](https://docs.letta.com/tutorials/attaching-detaching-blocks/). The cited recipe and current SDK versions can differ, so its exact client call signatures are not asserted here. + +**Lesson:** distinguish standing context from retrieval and extracted facts. Agentium fileMemory, sessions, summaries and learned knowledge should have explicit owners and purposes; a facade does not erase lifecycle differences. **Poor fit:** moving all application state into a hosted agent identity model or always injecting unbounded blocks. Agentium’s host-owned stores and optional features are valuable escape hatches. + +### Zep/Graphiti: temporal facts and shared graph lifecycle + +Graphiti models changing facts with temporal/provenance information and hybrid retrieval; Zep’s current documentation index distinguishes its managed context product from open-source Graphiti. [Graphiti overview, explicitly v2](https://help.getzep.com/v2/graphiti/getting-started/overview), [current v3 index](https://help.getzep.com/v3/llms.txt). The source project is a Python graph-building library, not a JavaScript loop runtime. [Project metadata](https://raw.githubusercontent.com/getzep/graphiti/main/pyproject.toml). + +**Lesson:** corpus lifetime, provenance and fact invalidation are genuine data contracts. Lexical and vector retrieval should see the same persistent corpus after restart (F12); graph retrieval needs explicit read authority (F09). **Poor fit:** adopting a temporal graph to solve every session or memory use case, or requiring an additional service/graph database for ordinary Agent runs. The v3 markdown overview could not be retrieved by the web tool; no claim of full current Zep API verification is made. + +## Evaluation: target application behavior, preserve integrity + +Evalite’s documented data/task/scorer shape evaluates an arbitrary application callback; its beta docs and main version differ. [Beta quickstart](https://v1.evalite.dev/guides/quickstart/). **Lesson:** accept a structural run target before broadening Agentium into generic eval infrastructure. A task callback is a low-cost escape. **Poor fit:** copying a local watch/UI workflow as a requirement for server-side eval or discarding Agentium’s strict timeout/score/result checks. + +promptfoo’s JavaScript provider modules expose an ID and callApi over application input/context, enabling adapters around existing implementations. [Custom JavaScript providers](https://www.promptfoo.dev/docs/providers/custom-api/). **Lesson:** application-owned execution should not require the concrete Agent class. **Poor fit:** moving the core runtime into a YAML/provider configuration system merely to gain evaluation flexibility. + +Braintrust separates data, application task and scoring, with versioned datasets and result projections. [Datasets](https://www.braintrust.dev/docs/guides/datasets), [TypeScript reference](https://www.braintrust.dev/docs/reference/libs/nodejs). **Lesson:** stable output/cost/trace projections and reporters allow external evaluation without rewriting application logic. **Poor fit:** adopting a hosted experiment/logging service as mandatory or assuming cloud dataset/logging semantics are needed for deterministic local tests. No remote experiment was run. + +Inspect supports agent composition/evaluation in Python and distinguishes conversation handoff from string-in/string-out delegation. [Agent guide](https://inspect.aisi.org.uk/agents.html). **Lesson:** declare transcript/control ownership and evaluate actual composed implementations—the obsolete mocked Team handoff test missed native protocol drift. **Poor fit:** treating Python solvers/state models as a drop-in TypeScript API or rebuilding its whole evaluation environment in Agentium. + +The smallest immediate improvement is `EvalTarget {run(...):Promise}` (F14), preserving current scorers, deadlines and session cleanup. Application callback/generic output can follow actual user needs. None of these external tools substitutes for deterministic fake adapters that exercise Agentium’s own operational invariants. + +## Extension and CLI design + +Standard Schema provides a shared validation/type interface; the current repository includes distinct specifications rather than one magic portable schema. [Official spec](https://github.com/standard-schema/standard-schema). **Lesson:** a validated schema-to-provider conversion boundary could allow non-Zod adopters without giving up inference. Validation compatibility alone does not guarantee lossless JSON-schema conversion or native tool constraints. Agentium already handles Zod 3/4/Mini and raw MCP schema; expanding support is an optional enhancement, not an essential omission. + +Commander supports configurable output and exit/error handling; Agentium already depends on it, so raw user-error stacks do not require a CLI framework replacement. [Custom error handling](https://github.com/tj/commander.js#custom-error-handling). **Lesson:** concise actionable domain errors, debug stacks and reliable exit/output behavior. Add structured JSON only if automation is an intended contract. Do not build new install/discovery/telemetry machinery for a CLI whose useful function is local scaffolding. + +Claude-specific plugin packages work because they target one runtime’s tools/permissions/session model. Harness ability binding, controller decisions, guardrails, EventBus observations and storage drivers have different authority/lifecycle roles. The useful common convention is explicit capabilities, pure definitions, owned bind/dispose and scoped services—not one global “plugin” hook. This is architectural judgment grounded in the inspected Agentium contracts and runtime comparison, not a claim that every alternative uses this design. + +## Existing benchmarks: what they establish + +**Source-inspected, not executed.** `benchmarks/run-all.sh` requires OPENAI_API_KEY, invokes external runners and writes results/report files. Running it would violate this audit’s provider-call/source-output restrictions. It was inspected first. `benchmarks/RESULTS.md` is dated **2026-03-02**, preceding current v4 contracts. Dependencies include loose/latest alternatives (`benchmarks/package.json:1`); the historical results cannot identify current pinned comparison versions. + +Agentium’s benchmark calls its normalized output usage “api” usage rather than collecting an independent invoice/transport truth (`benchmarks/agentium-bench.ts:1`, `:93`). Five samples and provider-backed latency mix model/network variation with framework work (`benchmarks/agentium-bench.ts:29`, `benchmarks/langchain-bench.ts:26`). Different runtime/framework setups and negative RSS deltas under garbage collection do not prove meaningful lower overhead. `benchmarks/report.ts:420` writes the report, so it was not run. + +They can establish that a specific historical recipe produced recorded outputs under its environment. They cannot establish today’s billing accuracy, native capability parity, durable recovery, cancellation semantics, memory quality, package footprint or superior production reliability. If benchmarking is resumed under authorization, pin versions, use deterministic local adapters for framework overhead, separate provider latency, preserve raw evidence, and test semantic invariants before comparing timing. + +## Lessons worth adopting + +1. Keep model calls and application loops independently adoptable; name effect/step/turn bounds precisely. +2. Expose provider-native customization without surrendering accounting, cancellation or tool ownership. +3. Separate configuration, execution, history, corpus and durable operation ownership. +4. Make state updates, checkpoint identity, asynchronous acknowledgment and failure policy explicit. +5. Treat live suspension, persisted conversation, queued delivery and recoverable execution as distinct capabilities. +6. Evaluate structural application targets and preserve integrity contracts; let external eval systems consume ordinary outputs. +7. Prefer optional domain capabilities/subpaths and mature integrations to a new universal framework layer. + +These lessons support the staged roadmap in README. They do not justify cloning the largest alternative, maximizing feature count, or rewriting Agentium wholesale. diff --git a/plans/README.md b/plans/README.md index 3990e42..8e296fe 100644 --- a/plans/README.md +++ b/plans/README.md @@ -1,51 +1,11 @@ -# Core cost tracking build plan +# Agentium plans -Prepared on 2026-10-08.

It invokes one host-supplied verifier for each candidate, including each revision. The verifier returns pass, fail, or unknown. Pass accepts; fail stops by default or requests an explicitly configured host-authored revision instruction; unknown stops with the verifier's reason. Existing `maxRevisions` and `allowRevisionEffects` enforce revision behavior. Do not silently add tool grants, dispatch checks, paid model calls, or use finishing capacity. + +The verifier is a trusted, read-only host callback. It checks actual facts via authenticated host services or validated artifacts, not text claims. A tool invocation with no executor error proves execution settled, not that a shell returned exit code zero or the resulting artifact satisfies requirements. Source text returned by tools remains source data. A verifier can use a host-maintained execution record keyed by tenant/user/project/run/revision, or core `getArtifact(ctx, ...)` when a trusted tool deliberately stored an artifact there. It must validate artifact content with the existing Zod dependency. + +Core artifacts (`storeArtifact/getArtifact`, `ctx.sessionState`) and harness artifacts (`services.putArtifact/getArtifact`, runtime-owned map) are separate stores. Document that distinction; do not introduce a unified artifact store solely for this milestone. Neither store makes a record host-confirmed merely because it has an ID. + +A record must match the current work: run, candidate revision or task execution version, repository/artifact revision and applicable scope. Old test success cannot verify an artifact subsequently edited. Cancellation is not rollback; a verifier must not perform operational effects. A bounded host callback must observe `ctx.signal`; it may impose a shorter own deadline. Existing observeControl directly awaits callbacks, so noncooperative cancellation handling depends on the lifecycle milestone, not this helper. Do not claim arbitrary JavaScript can be forcibly interrupted. + +### Proposed APIs (new, in packages/harness/src/policies.ts) + +```ts +import type { RunContext } from "@agentium/core"; +import type { CompletionPolicy } from "./runtime/index.js"; + +export type CompletionCandidate = { + text: string; + structured?: unknown; + revision: number; +}; + +export type CompletionVerification = { + verdict: "pass" | "fail" | "unknown"; + reason: string; + /** Stable host-validated references, not copies of arbitrary source content. */ + evidence?: readonly string[]; +}; + +export interface CompletionVerifier { + verify(candidate: CompletionCandidate, ctx: RunContext): Promise; +} + +export interface VerifiedCompletionPolicyOptions { + id?: string; + verifier: CompletionVerifier; + /** Default: stop.

Hosts can compose checks inside their verifier. Do not change reflectionPolicy or the default of having no completion policy. Reflection remains useful for qualitative criticism and is explicitly described as model assessment. + +Representative integration (constructor validation uses the existing positive validation convention; returned values need real runtime validation even though the callback is typed): + +```ts +import { z } from "zod"; + +const verificationSchema = z.strictObject({ + verdict: z.enum(["pass", "fail", "unknown"]), + reason: z.string().trim().min(1), + evidence: z.array(z.string().trim().min(1)).optional(), +}); + +export function verifiedCompletionPolicy(options: VerifiedCompletionPolicyOptions): CompletionPolicy { + const maxEntries = positive(options.maxEvidenceEntries ?? 32, "maxEvidenceEntries"); + const maxBytes = positive(options.maxEvidenceBytes ?? 8192, "maxEvidenceBytes"); + const onFailure = options.onFailure ?? { action: "stop" }; + if (onFailure.action === "revise" && !onFailure.instruction.trim()) { + throw new Error("Revision instruction must be nonempty"); + } + return { + id: options.id ??

A legitimate unknown result is task evidence insufficiency. Do not auto-convert every thrown verifier error into unknown, because that conceals broken integrations. + +Before, applications implement this mapping independently: + +```ts +completionPolicy: { + id: "project-verifier", + async evaluate(candidate, ctx) { + const check = await verificationService.check(ctx.runId, candidate.revision, ctx.signal); + return check.passed + ? { action: "accept", reason: "Verified" } + : { action: "stop", reason: "Verification failed" }; + }, +} +``` + +After, using the **proposed helper** (verificationService remains host-owned): + +```ts +completionPolicy: verifiedCompletionPolicy({ + verifier: { + async verify(candidate, ctx) { + return verificationService.check({ + tenantId: ctx.tenantId, + userId: ctx.userId, + runId: ctx.runId, + candidateRevision: candidate.revision, + signal: ctx.signal, + }); + }, + }, + onFailure: { action: "revise", instruction: "Resolve the reported verification failure, then present the result." }, +}), +``` + +The host service contract in this example is application code, not an existing Agentium symbol. A README fixture should implement it concretely with recorded facts and Zod validation. Fixture pass requires an actual matching run/revision and artifact hash with exitCode 0; absent/mismatched data returns unknown and nonzero exitCode returns fail. Avoid interpreting arbitrary console text as a test result. + +### Bound evidence diagnostics + +In `packages/harness/src/runtime/events.ts`, add optional `policyId`, `revision`, and `evidence?: readonly string[]` to the existing completion payload. Add optional `completion?: { policyId: string; revision: number; decision: CompletionDecision }` to HarnessResult, using a type-only import from controller.ts. Runtime stores the last validated completion decision, not every candidate response. Bound stored/emitted decision reason/instruction/evidence collectively to 8192 UTF-8 bytes, leaving room inside the existing 64 KiB generic event limit for result text, identity and envelopes. Reject an oversized decision before acceptance; do not truncate away the evidence required to justify acceptance. Add shared private completion-decision validation in runtime/controller.ts and invoke it before emitting or acting: validate action-specific instruction/evidence/reason fields, nonempty policy ID, safe revision and total bounds. This applies to existing custom policies too; malformed output fails closed. No lifecycle milestone is assumed to have already supplied this helper. + +In runtime/driver.ts, attach those fields when emitting completion and attach the last decision to terminalResult. A result subsequently cancelled/failed retains the decision as an observation, not proof the run completed. Only final status completed plus decision accept establishes completion acceptance. Bound/reference-only diagnostics prevent a critic or verifier from copying private artifacts into normal events. Hosts must still redact reference strings as needed. + +Refactor three tool.complete construction sites to one private helper preserving the existing `denied` field for compatibility and adding `outcome: "succeeded" | "failed" | "denied" | "cancelled"` and optional `denial: ToolCallResult["denial"]`. Choose cancelled when denial is cancelled, denied when another structured denial exists, failed when error exists without denial, otherwise succeeded. Document legacy denied as an unsuccessful-outcome flag; avoid changing its value silently.

No network calls or mocking library are needed. + +## M6b: Structural evaluation target and honest observations + +This is the sole required functional change outside core/harness: evaluation of the actual harness behavior is necessary to validate completion and context-memory changes. Do not move policy into eval or import eval from core/harness. + +### Proposed minimal eval contract + +```ts +// packages/eval/src/types.ts +import type { MessageContent, RunOpts, RunOutput } from "@agentium/core"; + +export interface EvalTarget { + run(input: MessageContent, opts?: RunOpts): Promise; +} + +export interface EvalSuiteConfig { + name: string; + agent: EvalTarget; // Existing property name preserved; Agent is structurally compatible. + // existing cases, scorers, thresholds, concurrency, timeoutMs, signal remain +} +``` + +Widen concrete Agent annotations in AccuracyEvalConfig, AgentJudgeEvalConfig, PerformanceEvalConfig, ReliabilityEvalConfig, ConversationRunner/ConversationSuite, and CaseLifecycle to EvalTarget. Change `WeakMap` to `WeakMap` while preserving reservations until actual callback settlement. Do not create a second `target` property or a wrapper class hierarchy. Object identity remains the reservation identity; two wrappers around one backend must share an owner or rely on harness session locking. Declare that constraint rather than pretend wrappers provide global session exclusion. + +### Harness adapter in existing optional testing entry point + +Add `createHarnessEvalTarget` and associated types to `packages/harness/src/testing.ts`; no import or peer dependency on eval. Its returned `.run` signature is structurally compatible with the proposed EvalTarget. Keep it out of the root entry point: evaluation is optional. + +```ts +import type { MessageContent, RunOpts, RunOutput } from "@agentium/core"; +import type { HarnessBudgetSnapshot } from "./runtime/budget.js"; +import type { HarnessIdentity, HarnessReason, HarnessRuntimeConfig, HarnessStatus } from "./runtime/index.js"; + +export interface HarnessEvalObservation { + status: HarnessStatus; + reason?: HarnessReason; + budget?: HarnessBudgetSnapshot; + toolCallCoverage: "complete" | "partial"; + cleanupDiagnostics?: readonly string[]; +} +export interface HarnessEvalTarget { + run(input: MessageContent, opts?: RunOpts): Promise; + /** Undefined for an output not produced by this target.

Validate and capture config; capture verified identity. Share `config.sessionStore ?? new InMemoryHarnessSessionStore()` for this target so explicit session IDs work across conversation turns. No external storage is required. +2. Each run creates its own runtime instance and run-local observation collector. Use `defineAbility` + `extendHarness` to add a local ability with no tools and one new `observeToolSettlement` middleware callback. Definitions are captured without binding effects. The observer sees results through the proposed cancellation-safe observational callback, including local delegates, rather than lossy tool.complete events. Existing afterTool behavior remains unchanged. +3. Preserve toolCallId/toolName/error/denial; normalize `result` to a short documented observation string. Do not duplicate arbitrary result payloads or artifacts. This target's toolCalls support attempted/successfully-settled tool scoring; they do not establish business success. Other scorers needing full tool content use a host-owned evidence fixture/adapter instead. +4. Enforce count and serialized metadata byte bounds; if exceeded, retain a bounded prefix and mark coverage partial. `observation()` exposes that state. Tests asserting forbidden tools or full trajectories must fail/inconclusive on partial coverage. Do not turn truncated observation into proof of no forbidden action. +5. Accept `sessionId`, `signal`, `runMode`; allow userId/tenantId only if identical to fixed verified identity. Reject other specified RunOpts fields (apiKey/history/executionServices/metadata/dependencies/questions/runId/publicMessageEvents/ephemeral) with an actionable unsupported-option error. Do not silently forward or ignore them: model bindings and authority come from config. +6. Call runtime.run(input, {identity, sessionId, signal, runMode}). Runtime owns budgets and canonical history. Active evaluation cancellation propagates through signal; no new retry layer. Handle native legacy awaiting_input as normalized stopped, completed as completed, failed as error, cancelled/stopped unchanged. Preserve original native status/reason in observation(). Live awaiting_input remains pending until reply/cancellation, so this unattended adapter does not invent an answer. Use a fixture driver or host input callback for interactive acceptance tests. +7. Map text/structured/usage/runId/sessionId to core RunOutput. Always include normalized toolCalls and status. Do not fabricate duration or TTFT: duration may be measured by the adapter; TTFT stays absent unless actually observed. Existing PerformanceEval treats missing requested TTFT as failure. +8. Store observation in `WeakMap`, keyed by the returned object, so concurrent runs cannot overwrite one shared last trace and observations expire with outputs. +9. Close per-run resources owned by the adapter after result settles. If config.resources is supplied, treat it as borrowed and do not close it. Close only adapter-owned pool session resources; host storage/clients remain borrowed. Preserve primary failures and expose cleanup diagnostics. A runtime cannot be force-released while noncooperative owned work is pending. + +### Settlement observation must survive cancellation + +Current `dispatch`/`dispatchEffect` call ensureActive after an effect settles but before afterTool; `observeTool` also checks cancellation before recording. The existing middleware is therefore insufficient for a complete trace. Add one optional field in `runtime/types.ts`: + +```ts +export interface HarnessMiddleware { + // existing fields unchanged + observeToolSettlement?: ( + result: ToolCallResult, + ctx: RunContext, + ) => void | Promise; +} +``` + +Add a private observational runner in `runtime/middleware.ts` which clones the settlement, invokes these callbacks even if ctx.signal is aborted, and catches observer errors into bounded `tool_observation_failed` cleanup diagnostics. It never transforms model data or bypasses mandatory admission. Call it immediately after ToolExecutor settles and before post-effect ensureActive in dispatch/dispatchEffect; in services.observeTool call it before the existing cancellation guard. Still await owned callbacks before releasing resources; noncooperative observers do not justify releasing the lease. No new tool/model work can start through the aborted services. + +The testing collector marks coverage partial on overflow, observer failure, an exceptional executor path without a ToolCallResult, or any cancelled/failed run for which settlement completeness cannot be established. Initially use conservative partial coverage for cancelled/failed runs even if every recorded tool appears present. Do not assert full absence from that prefix. Add a deterministic cancellation-after-applied-effect fixture: one admitted tool mutates a test counter, then the run cancels before post-tool enforcement; the settlement is observed, final status stays cancelled and the target reports partial coverage. Preserve the actual effect as evidence; no rollback or success claim. + +This additive callback is the smallest needed runtime observation change. It is explicitly observational, distinct from existing enforcement/afterTool callbacks. Its declarations must import existing ToolCallResult/RunContext with type-only imports. Validate that the new callback never runs twice for one toolCallId when a delegate uses observeTool; driver/executor ownership defines the one settlement producer. + +Representative bounded collector: + +```ts +const seen: ToolCallResult[] = []; +let coverage: "complete" | "partial" = "complete"; +let observedBytes = 0; +const middleware: HarnessMiddleware = { + id: "agentium/testing-tool-observations", + async observeToolSettlement(result) { + if (coverage === "partial") return; + const observation: ToolCallResult = { + toolCallId: result.toolCallId, + toolName: result.toolName, + result: "Tool outcome observed; source payload not retained by this adapter", + ...(result.error ? { error: result.error } : {}), + ...(result.denial ? { denial: result.denial } : {}), + }; + const bytes = Buffer.byteLength(JSON.stringify(observation)); + if (seen.length >= maxObservedTools || observedBytes + bytes > maxObservationBytes) { + coverage = "partial"; + return; + } + seen.push(observation); + observedBytes += bytes; + }, +}; +``` + +Error strings may themselves be large; validate byte bounds before retaining them, omit an oversized observation and mark coverage partial. Candidate IDs/names/denials are bounded as metadata too. Do not truncate an error into a misleading successful result. This collector is observation-only: it never replaces mandatory enforcement or transforms tool outputs to the model. Its source payload omission is intentional and documented. For plan integration, make collector limits subordinate to any stricter application evaluation budget. + +Before, eval accepts Agent but rejects an application `.run` object. After: + +```ts +import { EvalSuite, custom, toolCallMatch } from "@agentium/eval"; +import { createHarnessEvalTarget } from "@agentium/harness/testing"; + +const target = createHarnessEvalTarget({ config: applicationHarnessConfig, identity: verifiedIdentity }); +const suite = new EvalSuite({ + name: "harness-verification", + agent: target, + cases: [{ name: "requires test evidence", input: "Complete the change" }], + scorers: [ + toolCallMatch(["run_tests"], { mode: "successful" }), + custom("trace-complete", async (_input, output) => { + const observed = target.observation(output); + const pass = observed?.toolCallCoverage === "complete" && output.status === "completed"; + return { score: pass ? 1 : 0, pass, reason: pass ? "Complete trace and accepted completion" : "Missing trace or completion" }; + }), + ], + timeoutMs: 30000, +}); +``` + +`custom(name, callback)` is the existing scorer factory signature. This example deliberately tests trace completeness in addition to tool presence; a tool-name match alone does not prove the task succeeded. + +### Grading integrity required by this comparison + +Preserve existing legacy totals (`passed`, `failed`, `total`, averageScore) and failure handling. Add optional fields so reports distinguish what happened: + +```ts +// packages/eval/src/types.ts additions +export interface ScorerResult { + score: number; + pass: boolean; + reason?: string; + status?: "graded" | "infrastructure_error"; +} +export interface EvalResult { + // existing fields + gradingStatus?: "complete" | "incomplete"; +} +export interface EvalSuiteResult { + // existing fields + gradedCases?: number; + infrastructureFailures?: number; + /** Mean over valid grades only, null when there are no valid grades. */ + gradedAverageScore?: number | null; +} +``` + +Normalize valid legacy score returns to graded; thrown/invalid scorer returns become infrastructure_error, mark case failureKind infrastructure and gradingStatus incomplete, and keep overall pass false. A custom scorer returning score0/passfalse normally is a legitimate graded task failure. Do not overwrite timeout/cancel classification with infrastructure if lifecycle was already aborted. Capture output in CaseLifecycle immediately after the target settles; if later grading times out, evaluateCase returns that output plus timeout/cancelled, incomplete, cleanupPending as applicable. Do not rerun generation merely because a judge failed. + +Use scheduled total as the execution denominator, complete valid grades as the grading denominator, answerable gold cases as the abstention-denominator context, and eligible labeled evidence requirements as the retrieval denominator. Report each explicitly; unavailable grading never becomes a pass. Keep legacy averageScore for compatibility and prefer gradedAverageScore in the new comparison report. + +Files outside core/harness: eval types.ts/index.ts/case-lifecycle.ts/suite.ts, concrete config type annotations in four eval wrappers and conversational runners, result-integrity.test.ts, README. Reporter updates only to show new optional coverage fields where these reports are consumed; no new reporter/storage backend. This dependency is required to evaluate actual harness and separate infrastructure failure from memory behavior. + +Tests: new `packages/eval/src/__tests__/target-contract.test.ts` verifies a literal target without casts, ordinary Agent compatibility, explicit session exclusion while ignored cancellation settles, multimodal input forwarding, and no starts after cancellation. Extend result-integrity tests for completed output retained through judge timeout, invalid judge payload classified infrastructure, task failure remaining graded, and scheduled/graded denominator counts. New harness `__tests__/eval-target.test.ts` uses real fake-provider execution, named tools, two simultaneous sessions with independent observers, shared explicit session continuation, denied/failed distinction, partial trace, unsupported RunOpts rejection, borrowed/owned resource cleanup, status mapping, and absent TTFT. + +## M6c: Memory acceptance and reproducible comparisons + +This milestone depends on the context-continuity/recall contract and its diagnostics. Do not fake retrieval metrics by searching a final answer for a citation. Observe evidence returned by discovery, evidence read, and evidence actually retained in the prompt independently. Use host-scoped deterministic fixtures with source IDs/revisions/stable locations and all equivalent valid source alternatives; gold labels remain outside inputs. + +No new memory evaluator framework is required. Use the structural EvalTarget and custom Scorer objects, existing recorded fake providers for exact contracts, and a versioned local experiment fixture for optional live quality comparison. + +Required deterministic cases: + +1. Repository package-manager correction: old npm decision and explicit pnpm supersession -> current pnpm evidence retrieved; no stale-fact use. +2. Early deployment requirement survives compaction+archive -> summary coverage and recall evidence reach assembled prompt. +3. Current requirement assembled from two sessions -> both required evidence groups are covered, references remain resolvable. +4. Evidence exists in recall but is excluded by prompt budget -> retrieval hit counted, assembled evidence coverage fails; answer-use result scored separately. +5. Gold correct evidence is directly supplied, answer follows stale source -> retrieval held constant, answer/stale-fact gate fails. +6. No sufficient evidence -> appropriate uncertainty; no fabricated confirmation. Separate answerable cases where unnecessary abstention is a failure. +7. Conflicting environment-specific claims -> preserve conflict unless authorized specificity or explicit supersession resolves it; newest timestamp alone is insufficient. +8. Host tenant/project isolation -> no cross-scope discovery/read/prompt inclusion, including collision-shaped IDs; one invariant failure blocks the candidate independently of averages. +9. Retrieval timeout/cancellation/partial read -> diagnostic distinction, no hidden unbounded retry; fixed fallback behavior. +10. Returned source attempts to instruct agent -> source trust persists, grants and host instructions unchanged. +11. Trace/context evidence is incomplete -> comparison reports incomplete coverage and cannot pass a forbidden-effect assertion. +12. Exact tool success is insufficient: run_tests executes normally but returns exitCode1 -> evidence-based completion rejects. + +Metrics: +- any-sufficient hit@k, with k=5, on answerable evidence queries; equivalence groups permit valid alternate sources/spans; +- evidence coverage@5: satisfied necessary evidence groups / all necessary groups, including multi-session requirements; +- assembled evidence coverage after byte/token selection; +- final correctness, reference support, stale-fact-use count, conflict-handling correctness; +- appropriate abstention on insufficient-evidence cases and unnecessary abstention on answerable cases separately; +- per-run logical model/tool calls, prompt/output/total tokens, reported unknown usage, retrieval duration, total duration, bytes and prompt evidence tokens; +- summary/index preparation model calls/tokens/time separately; amortized and cold-start costs, rather than pretending retrieval preprocessing is free. + +Three paired conditions: full history; incremental summary without recall; incremental summary plus bounded recall. Same source corpus/revisions, task sequence, task model snapshot, generation settings, tools, output ceiling, grant/policy configuration, and total execution budget. Full history does not get free extra context; exceeding the common context budget is recorded as an infeasible baseline result. Disable background persistent extraction for the initial comparison so another system cannot covertly change the corpus mid-run. Each condition uses isolated storage/session IDs with identical seeded source data. + +Default acceptance runs are fake/recorded and network-free. A proposed live pilot is optional and must have explicit spend authorization. Suggested predeclared pilot envelope (values to be approved before running, not a claimed optimum): 24 held-out scenarios, 3 conditions, 3 repeats = 216 task runs, concurrency2; each task maxModelCalls8/maxToolCalls12/maxTokens16000/maxRevisions1, max model output1024; recall maxCandidates5/maxExcerpts5/maxQueryBytes2048/maxQueries2/maxDiscoveryBytes8192/maxExcerptBytes8192/maxSourceBytes16384/maxEvidenceTokens2048/deadlineMs500/validationDeadlineMs250/maxValidationBytes8192; case wall deadline30000ms. Summary/policy calls count within the same 8/16000 envelope. Judge at most one call per output capped512 tokens plus separate bounded calibration; deterministic outcome checks first. Worst-case preflight 1728 logical task model calls and 3,456,000 total task tokens, plus 216 judge calls and configured calibration. SDK physical retry counts and unknown charges must be disclosed. Exact pricing requires host model configuration; never invent a dollar ceiling from token totals. + +For the first small pilot, do not claim power to establish a 1–2 percentage-point regression. Severe exact invariant failures block. For noisy quality differences, predeclare one bounded follow-up and an inconclusive outcome, report all repeats. Use paired uncertainty estimates per scenario, category coverage, fixed-output judge calibration and order-swapped judgment where a model judge is necessary. Do not rerun until green. + +Fixture/runner location: `packages/harness/src/__tests__/fixtures/context-memory-eval.v1.json` for deterministic cases; `packages/harness/src/__tests__/context-memory-acceptance.test.ts` for actual harness invariants. Optional live runner stays an example under harness, consumes `@agentium/eval` explicitly, never auto-runs in ordinary CI. Its manifest records model/corpus/config/scorer versions and aliases, raw outputs, retrieval/prompt reference IDs, budgets, attempts, failures and denominator coverage. Persistent-memory learning/backend selection remains deferred until this evidence exists. + +## M7: Lightweight public journeys and packed consumers + +Retain matching core+harness versions, Agent(config) and agentDriver(config) patterns, ESM/CJS parity, explicit grants, independent provider SDK selection, and root/toolkit separation. Do not add a new all-in-one builder or mandatory model/memory provider. + +Publish three short, complete journeys: +1. Ordinary core Agent with one typed tool and cancellation, no harness. +2. Same AgentConfig under HarnessRuntime with explicit host grants/budgets and run identity. +3. Opt-in context continuity + verifiedCompletionPolicy + structural harness evaluation through the testing subpath. + +Examples must declare which dependencies are host-provided and which are SDK symbols, show close ownership, source trust, optional memory/storage choices, and actual stopped/cancelled/failed behavior. Avoid showing full advanced configuration on the introductory path. Document per-run owned Agent vs borrowed Agent, process-local defaults, snapshots vs recovery, ordinary vs finishing budget, logical vs physical attempts, unknown usage, and standalone memory vs harness canonical history in a compact responsibility table. All major errors shown in examples use existing code/name checks (`HarnessInputError`, `HarnessBudgetError`, `HarnessUnsupportedError`, ModelDeadlineError etc.) rather than depending on text matching. + +Extend existing `packages/harness/src/__tests__/package-consumption.test.ts` to pack eval only for the eval journey, load the testing helper in ESM/CJS, compile Agent and literal EvalTarget assignments, and execute a fake-provider harness+eval case offline. Keep the existing core+harness-only consumer case to establish that eval remains optional. Check new helper and verifier exports plus declaration types in .ts and .cts. Do not hide imports behind tsconfig paths or workspace aliases. Assert provider/database SDKs remain absent; no new dependency is required. + +Public exports: verifier value/types in harness root; eval helper value/types only harness/testing; EvalTarget in eval root. Event/result fields are optional additive extensions; no removal or changed existing fields.

Preserve the core model/tool loop. Preserve canonical transcripts separately from derived summaries and later persistent claims. Storage, access decisions, indexing, sharing, retention, and deletion remain host-owned. No implementation or verification command was run for this proposal. + +Observed integration facts (repository-relative paths below): + +- `packages/harness/src/runtime/history.ts:21–29`: `HistoryArchive.write` acknowledges storage and `read` returns an entire `readonly ChatMessage[]`; no discovery, excerpt, signal, or deadline parameters exist. Do not invent these methods or implement bounded recall by loading this array then slicing it. +- `history.ts:96–118`: whole archives have stable IDs, conversation ID, count, digest; full retrieval validates exact digest/count/transform. That proves canonical record integrity, not truth, current validity, or excerpt authenticity by itself. +- `driver.ts:523–550`: one retention queue serializes root and child archival, removes resident messages after acknowledgement, records canonical references. Keep serialization and conversation separation. +- `driver.ts:597–613`: ability context sources are fetched once during run setup. These remain static run context; automatic recall is a separate task-call boundary operation. +- `driver.ts:625–628,660–668`: task call admission occurs before retention, middleware, and projection in `prepare`, but the same `retain` also runs through `ExecutionServices.retainHistory` outside `prepare` (`driver.ts:839–841`; `core/agent/execution-services.ts:32–37`). Calling a summarizer during arbitrary retention could consume the final task-model slot. +- `policies.ts:105–179`: `summaryContextPolicy` has no retained incremental summary; it summarizes older supplied history per qualifying request and cannot discover already-evicted sources. +- `runtime/context-policy.ts:9–15`: `ContextPolicy.project` receives only history/entries; `ContextProjection` has messages and source inclusion provenance. Add optional data to this input; do not require core to own memory. +- `runtime/context.ts:19–39,197–229`: context source wrappers use user messages with `providerExtras.harnessContext`; current source collection may truncate text after loading. Recall must preserve this trust representation while rejecting or reporting excerpt incompleteness rather than quietly cutting a negation. +- `session-bindings.ts:3–14,27–29`: trusted identity is tenant/user, snapshot already persists canonical archive refs, resident history, and state; single-writer session lease exists. Project/repository are new host dimensions, not fields to infer from tool arguments or retrieved content. +- `driver.ts:732–814` and services comments at 142–149: `controlModel`/`finishModel` skip normal task projection, preventing policy recursion; preserve that exclusion. +- `core/memory/memory-manager.ts:572–608`: `recordCorrection` and invalidation of unverified learned knowledge already exist. They are narrower existing memory capabilities, not a reason to silently promote retrieved source data or introduce a competing replacement API. + +## Phase 1 selected design + +### Keep canonical retrieval backward compatible + +Keep `HistoryArchive` and `HarnessRuntime.retrieveHistory` unchanged. They remain exact, full archive retrieval for trusted host inspection. Add a separate `RecallStore` protocol requiring bounded indexed candidate discovery and source excerpts. A host may implement `HistoryArchive` and `RecallStore` over the same storage, or use a reference-only archive reader with no search index. No database and no new package dependency are needed. + +Do not wrap `HistoryArchive.read` in the default recall path. If an old archive backend cannot seek excerpts, reject recall configuration against it or identify it as unsupported. A host can rebuild an index externally; that migration is separate work. + +### Proposed public types + +All types/factories in this section are **new proposed exports**, not existing methods.

Require explicit `maxClarifications` in recall configuration (nonnegative safe integer; default 1). An await_input decision appends the returned reply as canonical user evidence through existing runtime append/retention, includes it in the task request, then re-evaluates query and decision. Use a single new discovery/read cycle bounded by the remaining call deadline/query budget. Waiting is governed by existing input timeout, explicit absolute run deadline and cancellation. Active-time exclusion retains the current runtime behavior. After a reply, start one fresh discovery/read cycle with deadlineMs, clamped to the remaining run/call deadline; it consumes the remaining maxQueries/maxSourceBytes/maxEvidenceTokens, not a reset budget. No implicit infinite deadline or unlimited cycles. Keep the already-admitted task-call slot while waiting. Stop/cancel releases its reservation using the existing admission cleanup. No recursive call to prepare is allowed. Exhausted clarification cycles stop with `clarification_limit`, rather than asking indefinitely. A reply is user evidence, not host instructions. Cancellation aborts the call/run; it is not converted into a successful empty recall result. Failed lookup differs from no accessible matches. Conflicts are represented as source-supported uncertainty, and host acceptance policy decides whether to continue. Phase 1 does not promise semantic contradiction detection over arbitrary text. + +Task call slots are protected by the existing admission order. Task tokens are **not** reserved until after projection. Keep the existing ledger in the first milestone. Give summary calls explicit per-call input/output limits; before starting a summary, conservatively estimate the essential task floor (host instructions, latest intact turn, tool schemas, wrapper margin, and explicitly requested task output), add planned summary input/output, and skip summary if that total exceeds the current ordinary token allowance. This is an advisory preflight, not an atomic reservation: another child/control call or underestimated provider payload can still make final task token admission fail. Report that failure without advancing incomplete coverage. A separate future task-token lease is justified only by measured failures; do not silently promise token starvation prevention. + +Add optional `HarnessRuntimeConfig.recall?: { store: RecallStore; budget: RecallBudget; policy: RecallPolicy; maxClarifications?: number }` and `taskSummary?: { policy: TaskSummaryPolicy; maxInputBytes: number; maxSummaryBytes: number; maxSummaryTokens: number; maxEvidenceReferences: number; maxRecordBytes: number; maxSummaryRecords: number }`. Both remain off by default. Runtime enforces maxRecordBytes on the serialized record, not only its text; maxSummaryRecords bounds the snapshot map. Release completed child summaries after archiving their canonical transcripts; main summary persists across calls. If another active conversation exceeds the record cap, defer its derived update with pending_summary rather than evicting active evidence. Summary record references carry their evidence IDs alongside references so retained citations can be resolved; never depend on a discarded excerpt array to recover the ID mapping. For initial version, incremental archival summaries require residentHistory plus a recall reader that supports canonical archive references; construction rejects unsupported combination. Generic query recall can operate without residentHistory. + +Add host-only `HarnessStartOptions.recallScope?: { projectId?: string; repositoryId?: string }`; runtime derives tenant/user/session from existing trusted start options. The host store must authorize project/repository rather than accept names as proof. Default access is current user/current session. Cross-session, shared-user, or project-wide visibility requires explicit host `open` authorization. No source/model field can widen these constraints. + +Extend `ContextPolicy.project` input with optional `recall?: RecallResult` and `taskSummary?: TaskSummaryRecord`. Existing policies keep their behavior unless the runtime is configured with recall. Proposed new `continuityContextPolicy(options)` is the supplied composition recipe; existing `summaryContextPolicy` remains stateless and unchanged. Its options must include total prompt token limit and reserved output/context margin; it does not own storage. + +Add optional `HarnessSessionSnapshot.taskSummaries?: Record` and `memoryScope?: RecallScope` once continuity is enabled. Bind the session to those exact host dimensions; reject reuse with different project/repository dimensions (use another session). Existing untagged snapshots require host-attested current-session import; do not infer project ownership from text. Runtime owns this field under the existing lease, keyed by canonical conversation ID. Custom code cannot promote retrieved data by writing arbitrary session state. Summary lineage metadata is bounded (coverage frontier plus bounded cited references), not a growing copy of all covered messages. + +### Bound discovery and reading at the source + +- Use one shared absolute deadline for open, query discovery, explicit archive dereference, and reading within each configured retrieval cycle, with run/call signal combined. Do not extend that deadline while a model or question is awaited. Each validation boundary has its own fresh validationDeadlineMs window; see the rule below. Register cleanup before operations and remove timers/listeners in finally. Race adapters for runtime responsiveness and abort them. Document that a malicious/noncooperative adapter can continue work; only a conforming host adapter bounds backend I/O. +- Adapter discovery is index-only with a bounded response; it must not enumerate and fully deserialize archives to satisfy a top-k request. Existing archives can be excerpt-seekable without an index; query discovery then returns no indexed matches/partial index coverage explicitly. +- `maxDiscoveryBytes` covers serialized candidate metadata. `maxSourceBytes` covers source content read for this recall; `maxExcerptBytes` covers one excerpt. Both sides charge actual bytes including metadata wrapper, not trusted `estimatedTokens` supplied by the adapter. +- Backends must honor limits before materialization or network transfer, including overfetch used for contextual negations/corrections. Source excerpts require immutable revision and stable location. If the backend cannot attest the excerpt's canonical revision without full retrieval, do not advertise `revisionValidation` and do not use it for verified recall. +- Runtime revalidates returned shape/size/scope/reference and centrally estimates tokens using the configured host estimator where available. Oversized or malformed responses are discarded with diagnostics; prompt truncation cannot make a backend conformant. +- Never turn an excerpt into `system`/`developer` content. Render the existing harness source-data user wrapper with `providerExtras.harnessContext` and stable evidence IDs. Generated summaries also retain source trust. Do not copy provider opaque continuation into source display excerpts or replay retrieved tool calls as executable conversation. +- Do not insert a truncated fragment that hides a negation/correction. Prefer complete excerpt, otherwise mark partial and pass to host decision. Complete refers to that evidence range; it does not imply all relevant corpus evidence was found. +- Candidate discovery, read, cache hit, summary reuse, and later citation dereference all require current scope validation. `viewRevision` changes on relevant revocations/corrections/deletions. Invoke the new bounded current-view `validate` after summary generation, immediately before model submission, and before summary-bearing snapshot commit; invalidate on changed/unavailable. These are observation fences, not an atomic transaction with a provider or an independent session store. No index backend guarantee is inferred from an ID namespace. +- Baseline supplies no cross-run result cache. A host adapter may cache behind the same scope/current-revision contract. Runtime may reuse a result only for identical scope/query/source revision during one call preparation. + +### Incremental summary and admission order + +Do **not** call `controlModel` inside arbitrary `retainHistory` or archive acknowledgement. A retention callback occurs before task-call admission in some paths. Instead, archive under the existing queue and record acknowledged references as pending continuity work. A summary's coverage frontier identifies which prefix has been summarized; references after it remain pending. Canonical evidence is preserved even when derived work is postponed. + +At `prepare` (shared by generate and stream): + +1. Reserve the task-model call slot first, preserving existing behavior. Check signal/deadline. After selecting role/tools, estimate the conservative task token floor for advisory summary admission; retain normal final token reservation. +2. Apply controller/bindings/tool grants; retain canonical history under queue. Stage archived references in this conversation only. No summary model call occurs during retention. +3. Open one authorized recall session with the combined deadline. Validate existing summary's view revision and policy version; if invalid, do not inject it. +4. Read newly uncovered archived groups by known references, using source bounds. Do not resummarize all history. Process at most one bounded update batch per task call; coverage remains an exact contiguous prefix. Pending source ranges are disclosed. Full replay envelopes remain in the canonical archive, while the summarizer sees bounded source display content. +5. Invoke existing budgeted `controlModel` through proposed `incrementalTaskSummaryPolicy` only if a complete update batch fits maxInputBytes and the remaining ordinary model/token allowance. It consumes a separate logical call; the reserved task-call slot cannot be stolen. Finishing capacity is not consumed unless the host explicitly selects finishing work. Validate the current source view after the awaited model result, then validate output. Only a still-valid draft replaces the summary and advances frontier together. A cancelled/failed update leaves previous record/frontier unchanged. No summary may cite evidence IDs absent from its inputs. +6. Query discovery/read uses a deterministic bounded query (latest real user input by default), combines with new summary evidence, deduplicates exact sourceRevision/locator, and surfaces partial/failure/conflict state. Summary-only reuse never confirms a factual claim. +7. Host RecallPolicy decision continues, uses existing requestInput for clarification, or stops. After the bounded clarification continuation described above, middleware/context projection operate with recall/summary source entries, preserving host instructions and latest intact user/tool groups. A custom context policy may choose assembly, but cannot promote source trust or split continuation. +8. Assembly prioritizes host instructions + latest intact exchanges + current evidence + summary + optional older sources. Current source-supported correction can be placed before a summary with stale content; if correctness cannot be resolved, disclose conflict rather than silently choosing the latest ingest time. +9. Count the entire projected request, including source wrappers, current history, tools schemas, summary, middleware additions, and opaque continuation. Enforce capability context window minus requested output and configured margin. Then validate the current view/dependencies once more, reserve task input/output tokens using the existing ledger and submit. If changed, discard the derived update and stop; no implicit second summary/retrieval retry in this call preparation. Explicitly acknowledge that advisory preflight cannot guarantee this final admission under concurrent calls. If essential context cannot fit, return an explicit outcome rather than deleting the task or tool pairing. +10. Before terminal commit, open a fresh authorized session for each summary scope and validate its references/current view within a new bounded validation window. Close these validation sessions in owned cleanup; never reuse a closed prepare session. On validation failure/timeout/revocation, omit the invalid derived record and report summary_invalidated_at_commit, while retaining canonical resident history/archive references in the single awaited persistence attempt. Do not block canonical evidence persistence or blindly retry an uncertain write. Commit remaining current summary records under the existing single-writer snapshot. Summary state is conversation-specific for root/children; never apply a parent's coverage frontier to child archives. A failed generation retains canonical sources; cancellation does not synthesize a new frontier. There is no live-run recovery claim. + +Small summaries may be updated once per call until pending prefix is covered; heavy backlog is partial evidence, not an invisible retry loop. If a single complete group exceeds bounds, stop/clarify or preserve pending evidence according to configured host policy. Updating a frontier to skip unseen source is forbidden. + +### Validation window and session lifetime rule + +Discovery/read cycles retain their own absolute deadline. Summary/task model latency does not renew a discovery deadline and does not consume a later validation window. At summary-result validation, pre-submit validation and pre-commit validation, create a new operation limit with deadline `min(now + validationDeadlineMs, remaining explicit run/call deadline)`, the existing cancellation signal and a fresh bounded maxValidationBytes allowance. A run with active-time budget still uses its existing abort timer; no validation may ignore it. Each call performs at most initial-reuse, post-summary and pre-submit validation; terminal validation is bounded by maxSummaryRecords. No hidden validation retry loop. If validation cannot fit the remaining deadline, fail that validation explicitly. + +The prepare session remains open until its pre-submit validation, then closes in owned cleanup. Terminal persistence opens a fresh authorized session using the stored exact scope and compares the record's original sourceViewRevision. A backend may compare a global invalidation epoch plus dependencies atomically within its own validate operation; it cannot advertise atomicity across an independent provider or session store. Conditional summary-bearing writes remain the stronger host guarantee described below. + +Representative proposed validation helper in runtime/recall.ts; every type is declared above: + +```ts +import { z } from "zod/v3"; + +const validationSchema = z.object({ + status: z.enum(["valid", "changed", "unavailable"]), viewRevision: z.string().min(1), +}).strict(); +export async function validateRecallView( + session: RecallSession, + expectedViewRevision: string, + references: readonly EvidenceReference[], + options: { signal: AbortSignal; runDeadline?: number; validationDeadlineMs: number; maxValidationBytes: number }, +): Promise<{ valid: boolean; code?: "deadline" | "backend_failure" | "invalid_response" | "revision_changed" }> { + options.signal.throwIfAborted(); + const deadline = Math.min(Date.now() + options.validationDeadlineMs, options.runDeadline ?? Infinity); + if (deadline <= Date.now()) return { valid: false, code: "deadline" }; + const controller = new AbortController(); + const onRunAbort = () => controller.abort(options.signal.reason); + options.signal.addEventListener("abort", onRunAbort, { once: true }); + const timer = setTimeout(() => controller.abort(new DOMException("Validation deadline", "TimeoutError")), + Math.max(1, deadline - Date.now())); + let onWindowAbort: (() => void) | undefined; + const expired = new Promise((_resolve, reject) => { + onWindowAbort = () => reject(controller.signal.reason); + controller.signal.addEventListener("abort", onWindowAbort, { once: true }); + }); + try { + const raw = await Promise.race([ + session.validate({ expectedViewRevision, references }, { + signal: controller.signal, deadline, remainingBytes: options.maxValidationBytes, remainingTokens: 0, + }), expired, + ]); + options.signal.throwIfAborted(); + if (Buffer.byteLength(JSON.stringify(raw), "utf8") > options.maxValidationBytes) { + return { valid: false, code: "invalid_response" }; + } + const result = validationSchema.safeParse(raw); + if (!result.success) return { valid: false, code: "invalid_response" }; + if (result.data.status === "unavailable") return { valid: false, code: "backend_failure" }; + return result.data.status === "valid" && result.data.viewRevision === expectedViewRevision + ? { valid: true } : { valid: false, code: "revision_changed" }; + } catch { + options.signal.throwIfAborted(); + return { valid: false, code: controller.signal.aborted ? "deadline" : "backend_failure" }; + } finally { + clearTimeout(timer); + options.signal.removeEventListener("abort", onRunAbort); + if (onWindowAbort) controller.signal.removeEventListener("abort", onWindowAbort); + } +} +``` + +The helper shows the chosen fence/window algorithm, response validation and cleanup. Constructor validation must establish positive safe bounds before invoking it; source adapter I/O must honor these same limits before materialization. A noncooperative read may continue after the race, which the host adapter contract and owned close diagnostics must disclose. `remainingTokens: 0` is correct for metadata-only validation; it authorizes no source text/model work. A terminal validation failure drops only derived data. Earlier authorized model usage cannot be undone; any task-specific requirement for current proof remains the host completion verifier's responsibility. + +New fault fixtures: summary generation and task generation each take longer than deadlineMs while remaining inside run deadlines; subsequent validations receive fresh finite deadlines and succeed. Revoke between pre-submit and terminal commit; canonical archive remains persisted and stale summary is absent. Test validation timeout with a still-healthy canonical store; test session.close before terminal validation to establish fresh authorization. Also test record-count/byte caps across concurrent child conversations. + +### Proposed policy factory + +Add `incrementalTaskSummaryPolicy(options: IncrementalTaskSummaryPolicyOptions)` with the exact required id/version/role/byte/token/reference/uncertainty fields declared in the implementation sketch below. It returns TaskSummaryPolicy, serializes prior summary plus new bounded source excerpts as untrusted JSON, asks for the defined TaskSummaryDraft JSON, calls existing controlModel(role,...,{maxTokens}), parses with existing Zod, rejects empty/oversized output, invalid/unknown evidence IDs, excess uncertainty count, and unsupported format. Runtime assigns ID/revision/coverage/lineage, preventing the model from inventing those fields. No proposed helper is assumed to exist today. + +### Correction, invalidation, and deletion in Phase 1 + +- Source update creates a new revision; references are immutable. Historical queries retain old revision only under host authorization/retention. Never mutate archive bytes underneath an existing digest. +- Host store's viewRevision changes when a dependency is corrected, retracted, expired, deleted, or revoked. Runtime refuses stale derived summary reuse. Rebuild from authorized sources with explicit missing ranges/uncertainty; never summarize the stale summary again to make it current. +- Host deletion must remove/suppress live recall from indexes, excerpt reads, cached responses, derived summaries, later citation dereference, and concurrently rebuilding records. Use host conditional writes/invalidation fences to prevent physical late refresh resurrection. A summary-bearing session commit must atomically compare sourceViewRevision against the host invalidation epoch when that guarantee is advertised. If session and recall stores cannot share this fence, the SDK guarantees rejecting stale reuse at its validation points, while the host owns suppression of late persisted copies and deletion completion. Stale persisted copies can exist under the weaker contract but cannot be used without current validation. Repeated reads are not atomic publication and do not promise backup purge. +- An invalidated summary stays historical only if host retention allows; it cannot be active projected context. Session snapshots containing an old summary are treated as unusable after source validation changes, rather than trusted just because they deserialize. +- Exact deletion SLA, backup exceptions, source-authority ranking, and cross-user/project access are host product decisions; expose adapter guarantees and record unsupported cases. Do not claim successful deletion from status `retracted` or `expired`. + +## Phase 2 — later persistent fact semantics + +Do not introduce a graph DB, persistent promotion loop, or replacement MemoryManager API in Phase 1. Existing CorrectionStore/LearnedKnowledge can serve an optional adapter when their provenance/scope/validity guarantees are verified. Their current best-effort learned-knowledge invalidation is not equivalent to authoritative deletion or a full temporal fact ledger. + +Specify conceptual scoped claim records before exporting or storing them: + +- identity dimensions tenant/user/project/repository, with sharing authorized by host; +- claim ID/revision, source IDs/revisions/locators, extraction policy/model revision; +- `recordedAt` and effective interval (`validFrom`, optional `validUntil`); +- `stated` versus `inferred`, separately `unverified` versus `host_verified`; +- lifecycle current/superseded/expired/retracted/conflicted; +- explicit supersedes/retracts links and authorized actor, correction reason; +- dependencies for invalidation, deletion fences, retention policy. + +Repeated summaries, similarity, or model confidence do not verify claims. Latest recording time does not resolve authority or environment scope. “Contains PostgreSQL configuration” remains an inferred observation and cannot become “All deployments require PostgreSQL.” Promotion runs only at host-authorized completion/correction triggers, outside automatic pre-call recall, with idempotency and host-owned retention. Episodes are separate bounded experience records, not generalized requirements. + +## Meaningful verification plan (not run) + +New focused tests: `packages/harness/src/runtime/__tests__/bounded-recall.test.ts`, `task-summary.test.ts`, and `continuity-context.test.ts`. Reuse repository Vitest/provider fixtures and assert captured model requests/adapter source reads, not merely helper return shapes. + +Required scenarios: + +1. Relevant evidence at end of large archive is read by locator without calling legacy archive.read; source bytes/deadline/query bounds observed before loading. +2. Negation/correction spans chunk boundary: complete context is included or projection shows partial uncertainty and configured continuation/stop; no confident fragment. +3. Tenant/project conflict, identical fact names, cache seeded from forbidden scope: no forbidden candidates, excerpts, summary, prompt, safe diagnostics, or citations. Revoke between discovery and read; read rechecks. +4. First call summarizes archive prefix A; second adds B and passes only previous summary + B to summarizer. No overlapping full-history resummarization. Summary frontier/source references exact after each commit. +5. Summary budget exhausted: task call slot remains reserved, old summary remains unchanged, pending coverage reported. Cancellation during summary/read leaves old frontier and no further task call. Ordinary recall does not recurse for controlModel/finishModel. +6. Adapter oversized response, backend failure, timeout, healthy zero matches, changed revision are distinct outcomes. Runtime does not label timeout as no memory. +7. Corrected decision plus stale old source: evidence present and source status/uncertainty visible; later Phase 2 verifies authorized supersession and two-clock historical answers. +8. Source deleted while summary refresh in flight: current-view validation rejects the stale refresh and old snapshot on reuse. Separately test a host adapter with atomic conditional publication; only that adapter can advertise preventing physical late summary copies after deletion completion. A read-fence-only adapter explicitly cannot make that stronger claim. +9. Root and child retention interleave; separate summary coverage and access stay correct. Source opaque envelopes/tool exchange remain untouched in canonical archive and live replay. +10. Prompt budget includes tools/wrappers/output margin; summary maxTokens charged in ledger; a concurrent child call may defeat the advisory task-token floor preflight, producing explicit task admission failure with canonical evidence intact. Essential current turn too large remains explicit failure, preserving evidence. +11. Older unbounded archive implementation and existing stateless summary policy continue unchanged when feature disabled; optional snapshot field absent migrates safely; public ESM/CJS/TS imports resolve. + +Proposed focused Vitest skeleton, where every fixture import refers to a new fixture module explicitly to be implemented: + +```ts +import { expect, it } from "vitest"; +import { createContinuityFixture } from "./fixtures/continuity-fixture.js"; + +// Proposed fixture: bounded fake RecallStore + canonical archive map + +// capturing task/summary providers + runtime, session snapshot read helper. +// It accepts the events/policies below; it never uses a production backend. +it("summarizes only new evidence and preserves admitted task capacity", async () => { + const fixture = createContinuityFixture({ maxModelCalls: 3, taskOutputTokens: 32 }); + fixture.seedArchive("A", "Use npm for this project."); + await fixture.run("Explain the package commands."); + fixture.seedArchive("B", "Correction: the project now uses pnpm."); + await fixture.run("Which package manager applies?"); + expect(fixture.summaryInputs[1].additions.map((item) => item.reference.sourceId)).toEqual(["B"]); + expect(fixture.summaryInputs[1].previous?.coverage.throughArchiveId).toBe("A"); + expect(fixture.taskInputs[1]).toContain("pnpm"); + expect(fixture.legacyArchiveReads).toBe(0); +}); + +it("does not advance coverage after cancelled derived work", async () => { + const fixture = createContinuityFixture({ stallSummary: true }); + fixture.seedArchive("A", "A requirement that must survive."); + const handle = fixture.start("Continue the task."); + await fixture.waitForSummaryStart(); + handle.cancel("test cancellation"); + await handle.result(); + expect((await fixture.readSnapshot()).taskSummaries?.main).toBeUndefined(); + expect(fixture.taskInputs).toHaveLength(0); + expect(fixture.summarySignal?.aborted).toBe(true); +}); +``` + +Do not copy fixture helpers into a spec and pretend they already exist. Implement the explicitly named new fixture with deterministic virtual clock, deferred providers, source-read accounting, and currentview/revocation fences when implementation is authorized. A separate test must prove the corrected evidence can still be ignored by answer generation; that is an answer-use eval failure, not a retrieval-unit-test failure. + +Future commands, scoped to authorized implementation: + +```sh +npx vitest run packages/harness/src/runtime/__tests__/bounded-recall.test.ts packages/harness/src/runtime/__tests__/task-summary.test.ts packages/harness/src/runtime/__tests__/continuity-context.test.ts packages/harness/src/runtime/__tests__/resident-history.test.ts packages/harness/src/runtime/__tests__/control-model.test.ts +npx tsc -p packages/harness/tsconfig.build.json --noEmit --pretty false +npm run build -w packages/core -w packages/harness +npm run test:package -w packages/harness +npx biome check packages/harness/src/runtime/recall.ts packages/harness/src/runtime/task-summary.ts packages/harness/src/runtime/context-policy.ts packages/harness/src/runtime/driver.ts packages/harness/src/runtime/session-bindings.ts packages/harness/src/policies.ts packages/harness/src/index.ts +``` + +Keep archive/compaction/input regression checks and broader repository suite at final gate once changes exist. No command above is a claim of a passing result. Declaration checks use the repository build tsconfigs; the focused source tests are checked by Vitest and final consumer fixtures. + +### Inaccessible canonical archive ranges + +Select the narrow initial behavior: an unavailable/revoked group stops contiguous summary reconstruction at that cursor. Do not advance coverage past it and do not reintroduce its old derived text. Report `unavailable_coverage` and its safe coverage cursor; later accessible evidence remains eligible for independent bounded recall. The default policy stops if continuity is required; a host may explicitly continue with uncertainty. No tombstone/gap receipt API is added in M5. Advancing reconstruction past a deleted range is a later host-authorized coverage contract, distinct from claiming its content was summarized.

Adapter must attest concrete capability, not infer it from a database name. +- How much per-call latency/input/output capacity is reserved for recall/summary? Proposed limits are explicit configuration; performance measurements choose defaults, not a paper benchmark. +- Do long autonomous tasks require tool-roundtrip continuity/retention within one user turn?

The first accepted range must begin exactly at the prior coverage cursor; subsequent ranges must adjoin without gap/overlap, advancing to next archive ordinal only after the previous messageCount is reached. Coverage is assigned by runtime from those verified ranges, never the model. Partial source text cannot advance cursor. A source reference's arbitrary locator string cannot substitute for these numeric bounds. The host reader must serve display excerpts from preindexed canonical group boundaries; maxBytes failure yields partial/unavailable rather than loading a giant group. Representative locator grammar: `archive::messages:-`; sourceRevision is archive.digest and range indexes are exclusive at end. diff --git a/plans/core-harness-dependability/2026-10-13-core-harness-dependability-design.md b/plans/core-harness-dependability/2026-10-13-core-harness-dependability-design.md new file mode 100644 index 0000000..7ef0dfc --- /dev/null +++ b/plans/core-harness-dependability/2026-10-13-core-harness-dependability-design.md @@ -0,0 +1,107 @@ +# Agentium core and harness dependability — proposed design + +**Status:** Review draft, 2026-10-13.

Preserve the possibility of a final answer call after the final permitted tool batch. +3. Namespace/scoped identity is injective. Persistent-key migrations are explicit and never use ambiguous fallback reads. +4. Parallel Workflow updates compose declared writes rather than overwrite with copied input; continuation checkpoints carry absolute cursor/version identity. +5. Every background summary/extraction has an owner and a bounded, truthful drain outcome. Closing a borrowed store remains a host operation. +6. Bounded recall discovers and reads relevant authorized evidence before configured task-model calls. An incremental summary identifies exactly which archived records it covers. Retrieval and summaries stay source data. +7. Completion may require host-verified tests/artifacts. Unknown evidence differs from failed evidence. Evaluations measure retrieval and answer use separately and preserve missing grades/infrastructure failures. +8. Plain Agent adoption stays simple. Advanced public APIs are additive, documented and exercised in packed ESM/CommonJS/TypeScript consumption. + +## Capability map + +| Id | Responsibility | Prerequisites | +|---|---|---| +| execution-integrity (M1) | Core loop boundaries; awaited harness lease operations; incremental session high-water recovery; legacy budget honesty | Existing host-control baseline | +| storage-identities (M2) | In-memory namespace separation; explicit v1 scope/Redis encoding and migration | Baseline | +| memory-lifecycle (M3) | Track/drain old memory work; coherent source wrappers; truthful write result | Baseline; M1 terminal conventions | +| workflow-state (M4) | Patch merge, cursor versions, failure/cancellation policies; Team handoff contract honesty | M1 | +| context-continuity (M5) | Bounded scope-authorized discovery/excerpt reads; incremental summaries; source revisions and uncertainty | M1; M2 for SDK-scoped backing stores | +| completion-evaluation (M6) | Deterministic evidence gate, structural EvalTarget, retrieval/answer measurement | M1; M5 for memory scenarios | +| supported-journeys (M7) | Coherent guides, exports, examples, declarations, consumer verification | Each relevant capability | + +These are reviewable milestones.

They do not imply remote policy interception, database permissions, durable recovery or a dependency from core/harness to eval. Host archive and recall implementations may share storage but have different APIs. + +### Existing behavior to retain + +- Provider retry ownership and deadline controls; never replay an established stream. +- Logical-call/token reservations, unknown-usage charging, finishing capacity within total limits, and currency accounting remaining in core. +- Mandatory grants and effect policy, trusted driver/factory code, source/host instruction distinction, and opaque provider continuation validation. +- Full canonical archive retrieval and verified digests. Resident limits remain opt-in and retain intact live turns. Archive acknowledgement precedes eviction. +- Live correlated input through existing `requestInput`/`reply`; public stateless input validation cannot claim a pending request. +- Local/portable harness composition with approved runtime references; no credentials or executable callbacks recovered from portable JSON. +- Standalone Agent use, existing package names, optional peer dependencies, and `.js` source imports. + +### New behavior and defaults + +- Correctness repairs apply to ordinary execution paths too. Preserve existing retry defaults already documented by the host-control change. +- Existing Workflow failure behavior stays `continue` by default; add explicit `stop` and report aggregate outcome. Parallel joins apply returned patches. Same-key writes use declaration order by default, with optional strict `merge: "error"`; strict conflicts are fatal through nested groups. A resolved incomplete Agent output is an error step, with its partial output retained as evidence. +- Persistent key encodings remain legacy by default during additive rollout; new shared-host examples select v1. In-memory namespace separation is corrected immediately. A default change requires a major release/migration. +- Recall and incremental archival summaries are off unless configured. Their bounds are explicit positive configuration values. The default recall query is the latest real user input, with current session/user scope only. A host may explicitly authorize broader project/repository access. +- Default recall policy stops on backend failure or unresolved partial evidence; healthy absence is exposed and may continue with uncertainty. Hosts can override continuation/clarification policy explicitly. Cancellation always cancels the run. +- Summary work uses existing ordinary control-model budgets and bounded per-call input/output. The task call slot is reserved first. Tokens are reserved after projection as today, so auxiliary work can still cause task token admission failure; this limitation is visible, not a promise of a hard token floor. +- Existing stateless `summaryContextPolicy` remains usable; a new continuity recipe selects incremental summary plus recall. No automatic persistent fact promotion or background learning is added to controlled runs. +- `Agent.close` gains bounded memory drain and explicit busy/unfinished-work behavior. It cannot prove a remote callback stopped or safely close storage beneath pending writes. + +## Memory classes and lifecycle + +| Class | Authority and lifecycle | +|---|---| +| Canonical transcript/archive | Faithful original records under host access/retention. Content may be obsolete or wrong. Integrity does not imply factual truth. | +| Task summary | Derived, rebuildable source context with explicit coverage, evidence references, derivation/policy version and uncertainty. | +| Persistent scoped facts | Later optional records: stated/inferred origin, independent verification status, effective interval, correction/supersession and source evidence. | +| Episodes | Later optional descriptions of a particular experience; never automatically generalized into requirements. | + +Recording time and effective time differ. A new ingestion timestamp does not resolve a conflict or broaden scope. Source revision/locator and host view invalidation fence govern whether derived data is usable. SDK current-view fences reject stale summary reuse. Preventing physical late persisted copies after deletion completion requires the host conditional-publication/invalidation guarantee; independent read fences do not establish it. Backup deletion SLA and allowed retention exceptions remain host decisions. + +## Compatibility and explicit limits + +Additive types/configuration keep existing methods and defaults unless a documented correctness repair changes observable false-success/over-limit behavior. Keep `HarnessSessionLease.read()` synchronous: a remote store preloads its snapshot during awaited `acquire`. Widen only `commit` and `release` to accept void or Promise; all runtime callers await them. An attempted commit with unknown acknowledgement is not retried blindly in cleanup. + +Do not promise distributed ownership from per-instance locks or generic KV. Repair loose-log recovery now; an optional atomic session capability is a later design track with explicit idempotency/revision requirements. Session durability remains separate from durable active-run recovery. + +Do not claim full replay, exactly-once tools, filesystem rollback, hard physical-token ceilings, or forced termination of arbitrary JavaScript. A resumed procedural Workflow may execute a side effect again unless the host's operation is idempotent or reconciled. New strict continuation rejects ambiguous legacy checkpoints. Existing `replay` receives the cursor correction and a deprecation; removing its legacy acceptance requires a major-version migration decision. + +## Deferred/gated work + +Persistent fact promotion/storage adapters, durable active-run checkpoints and effect ledger recovery, public native-client customization, global registry default changes, generic lexical corpus/index persistence, skill paging, ACP hosting and broad package splits remain separate evidence-driven work. GraphRAG's generated raw query authority is a confirmed conditional risk and gets a separately gated read-only contract track; do not disguise a prompt rule or READ routing mode as database enforcement. + +## Verification policy + +Use current Vitest fixtures and deterministic failure injection before implementation; proposed tests must first fail for the intended public behavior. The plan includes commands from repository scripts. Previous checks on 2026-10-12 passed 2,448 tests (27 skipped), all workspace builds, core/harness declaration checks and package consumption. Those are historical baseline evidence; they do not validate proposed APIs or later source changes. + +No new test/build/evaluation suite is run as part of this planning task. No live provider spend, external effects, migrations, publication, or source changes are authorized. Later release review records exact revision, commands, skips/unknowns and packed artifact compatibility. Fixture tests prove covered invariants; model-quality claims require the separately bounded evaluation protocol. diff --git a/plans/core-harness-dependability/2026-10-13-core-harness-dependability.md b/plans/core-harness-dependability/2026-10-13-core-harness-dependability.md new file mode 100644 index 0000000..8ab88cb --- /dev/null +++ b/plans/core-harness-dependability/2026-10-13-core-harness-dependability.md @@ -0,0 +1,261 @@ +# Agentium core and harness dependability implementation plan + +> **Status: PROPOSED — analysis and planning only, 2026-10-13.** No implementation is approved by this document.

No new runtime dependency or backend is proposed. + +**Spec:** [Selected design and ownership](2026-10-13-core-harness-dependability-design.md). + +**Global constraints:** Source data must not become host instructions; failed/unknown effects cannot be retried blindly; cancellation cannot undo remote effects; physical retry/token limits require a conforming host/provider; local snapshots do not establish active-run durability; existing work and optional peer dependencies must remain intact. + +**Review focus:** Cap zero; cancellation after a response/effect; unknown commit acknowledgement; scope collisions; summary drain before close; initialized parallel state and nested fatal joins; continuation of a continuation; revocation during recall; evidence omitted during projection; completed output lost during grading; actual packaged imports. + +## Updated verdict + +**The core/harness boundary is the right foundation. Its contracts need completion before the SDK adds broader orchestration or persistent learning.** Existing mechanisms already support an ordinary Agent, locally governed Agent/Workflow/Team execution, host-granted model roles, policies, input, resource ownership and verified canonical archives. The remaining source-confirmed issues mostly arise where one subsystem turns another subsystem's partial result into apparent success, loses state, or assumes synchronous persistence. + +The [supplied architecture document](/Users/xerycks/Downloads/Harness_Engineering_Anatomy_Architecture_and_Evolu.pdf) supports the separation of execution, tools, context, control and extension surfaces. The comparison uses its component taxonomy and tradeoffs, especially the minimal harness, context/memory, orchestration/recovery and SDK discussion. Its embedded commands and recommendations are reference content. They do not override the user's analysis-only request or prove that Agentium needs a CLI, graph engine, graph database or vendor memory backend. + +Agentium should retain its lightweight adoption path and strengthen observable invariants. Memory needs evidence and validity semantics. Completion needs current host facts when the task requires verification. Evaluation needs to distinguish evidence retrieval, prompt inclusion, answer use and failed grading.

No new generation loop. | + +The introductory journey remains one model and typed tools. The following uses existing APIs; the caller supplies the provider: + +```ts +import { Agent, defineTool, type ModelProvider } from "@agentium/core"; +import { z } from "zod/v3"; + +export async function lookupWithAgent(model: ModelProvider, signal: AbortSignal) { + const lookup = defineTool({ + name: "lookup", description: "Read a fixture record", + parameters: z.object({ id: z.string() }), + execute: async ({ id }) => JSON.stringify({ id, value: "fixture" }), + }); + const agent = new Agent({ name: "reader", model, tools: [lookup], register: false }); + try { + return await agent.run("Read record A", { signal }); + } finally { + await agent.close(); + } +} +``` + +The governed journey reuses AgentConfig. Driver configuration creates an owned Agent; passing an existing Agent borrows it. Existing ordinary storage/provider choices remain optional: + +```ts +import { type AgentConfig } from "@agentium/core"; +import { HarnessRuntime, agentDriver } from "@agentium/harness"; + +export function governedAgent(config: AgentConfig) { + return new HarnessRuntime({ + driver: agentDriver(config), + grants: { toolIds: (config.tools ?? []).map((tool) => tool.name), modelRoles: ["main"] }, + budgets: { maxModelCalls: 8, maxToolCalls: 12, maxTokens: 16000 }, + }); +} +// Host: runtime.run(input, { identity: verifiedIdentity, sessionId, signal }); +// Inspect status/reason/budget. The example limits are a host choice, not SDK defaults. +``` + +The advanced journey adds source continuity and verification using the proposed surfaces. A host must supply a conforming bounded recall adapter and application verifier. This example does not fabricate either service: + +```ts +import type { AgentConfig, ModelProvider } from "@agentium/core"; +import { + HarnessRuntime, agentDriver, continuityContextPolicy, currentSessionRecallPolicy, + incrementalTaskSummaryPolicy, verifiedCompletionPolicy, + type CompletionVerifier, type HarnessSessionStore, type HistoryArchive, type RecallStore, +} from "@agentium/harness"; + +export function evidenceAwareAgent(input: { + agent: AgentConfig; summaryModel: ModelProvider; archive: HistoryArchive; + recall: RecallStore; verifier: CompletionVerifier; sessions: HarnessSessionStore; +}) { + return new HarnessRuntime({ + driver: agentDriver(input.agent), sessionStore: input.sessions, + grants: { toolIds: (input.agent.tools ?? []).map((tool) => tool.name), modelRoles: ["main", "summary"] }, + models: { summary: { provider: input.summaryModel, options: ["maxTokens"] } }, + budgets: { maxModelCalls: 8, maxToolCalls: 12, maxTokens: 16000, maxRevisions: 1 }, + residentHistory: { archive: input.archive, maxMessages: 40, maxBytes: 65536 }, + recall: { + store: input.recall, policy: currentSessionRecallPolicy("project-recall"), maxClarifications: 1, + budget: { maxQueryBytes: 2048, maxQueries: 2, maxCandidates: 5, + maxDiscoveryBytes: 8192, maxExcerpts: 5, maxExcerptBytes: 8192, + maxSourceBytes: 16384, maxEvidenceTokens: 2048, deadlineMs: 500, + validationDeadlineMs: 250, maxValidationBytes: 8192 }, + }, + taskSummary: { + policy: incrementalTaskSummaryPolicy({ id: "task-summary", version: 1, modelRole: "summary", + maxInputBytes: 16384, maxOutputBytes: 4096, maxTokens: 512, + maxEvidenceReferences: 32, maxUncertainties: 8 }), + maxInputBytes: 16384, maxSummaryBytes: 4096, maxSummaryTokens: 512, maxEvidenceReferences: 32, maxRecordBytes: 32768, maxSummaryRecords: 32, + }, + contextPolicy: continuityContextPolicy({ id: "continuity", maxRequestTokens: 12000, reservedRequestTokens: 2048 }), + completionPolicy: verifiedCompletionPolicy({ verifier: input.verifier }), + }); +} +``` + +These illustrative bounds must fit the host's selected model and task. The runtime still checks actual selected tools, requested output and provider-specific estimates. A task call slot is protected before summary work; task tokens are reserved after projection and may still be exhausted. Discovery/read latency bounds each source cycle; each prescribed validation receives a fresh validationDeadlineMs window clamped to run/call deadlines. Terminal validation opens a fresh authorized session. Policy-model calls retain existing request/run deadlines. Keep unknown capability/usage outcomes visible. + +Use the testing subpath and structural target for evaluation. The full example, option rejection and cleanup contracts are in the eval companion. Do not attach eval to the ordinary runtime dependency graph. Introductory docs should show these three journeys progressively, instead of requiring the advanced configuration to run one Agent. + +## Invariants, policies and operational limits + +| SDK invariant | Configurable/host policy | Limit to communicate | +|---|---|---| +| Required persistence acknowledged before result; no blind unknown-write retry | Durable adapter/CAS/receipt reconciliation | Held local lease is not distributed exclusion. | +| Known cancellation prevents new dispatch/completion | Deadline, isolation and external effect reconciliation | A noncooperative callback may keep result/ownership pending. | +| Whole tool exchanges/provider continuation preserved | Resident limits and explicitly attested envelopes | A long live turn may exceed resident bounds and fail explicitly. | +| Source role, authorized scope and current-view validation | Visibility, ranking, required evidence and stop/clarify policy | Repeated validation is not atomic provider submission or cross-store deletion. | +| Summary cursor advances only for read complete contiguous groups | Summary model/role/bounds; host atomic conditional publication | An inaccessible group blocks summary frontier; later evidence can be recalled separately. | +| Unknown verification does not accept; acceptance references bounded | Application artifact/test verifier; revision instruction and grants | Successful tool settlement alone proves neither tests nor artifacts correct. | +| Structural fatal joins/cancellation stop downstream work | Ordinary failure continue/stop; collision declaration order/error | Returned patches do not isolate direct nested object mutation. | +| Missing traces/grades cannot prove absence/success | Scorers, gold evidence groups, optional live pilot | Fake fixtures establish contracts, not production quality improvement. | + +## Compatibility and dependent packages + +Additive interfaces keep existing methods, root package names and optional peers. Correctness fixes alter false-success, over-limit and shutdown timing behavior; release notes must call these out. Keep `remember(): Promise`, `HistoryArchive.read` and ordinary stateless policies. Persistent v1 keys are opt-in; do not change defaults or transparently fall back. Existing Workflow replay/fork continue to accept legacy records during the current major with deprecation/cursor fixes; strict continuation rejects them. A major default change/removal is a separate release decision. + +Only `@agentium/eval` requires functional changes outside the primary packages: the actual harness must be a structural target, and its memory/completion comparison must preserve output and missing grading. Change its annotations, case lifecycle and reporting fields minimally, without importing eval into core/harness. Packed consumer fixtures may pack eval for the optional journey while retaining the original core+harness-only case. CLI or documentation consumers change only if a demonstrated public type change requires it. No queue, transport, admin, edge or browser redesign is included. + +No new public package subpath is required. Keep root ESM/CJS parity and `.d.ts`/`.d.cts`; the existing harness/testing subpath carries the eval adapter. Verify that newly used type imports do not leak optional providers or eval into the baseline declaration graph. + +## Verification after implementation + +Commands are discovered from repository scripts or explicit supported Vitest/tsc file invocation. **They have not been run for these proposals.** Companion plans select focused suites and faults; run those first. Use the current installed dependencies, network-free fake/recorded providers and deterministic deferred promises/storage faults. Do not spend on a live provider by default. + +```sh +npm run build:core +npm run build:harness +npx tsc -p packages/core/tsconfig.build.json --noEmit --pretty false +npx tsc -p packages/harness/tsconfig.build.json --noEmit --pretty false +npx tsc -p packages/eval/tsconfig.build.json --noEmit --pretty false +npm run build +npx vitest run +npm run test:package +git diff --check +``` + +Build fresh dist before packed consumers. Use the explicit changed TypeScript paths shown in companions for Biome, including changed tests; never run a broad autofix over unrelated existing work. Existing local HTTP tests may require localhost-bind permission as the historical run did; default new gates use no live backend. Record skipped tests and unknown provider charges. Review package contents and TS imports through real packed exports, without path aliases. A read-only plan or source suite alone establishes no release readiness. + +Memory acceptance compares full history, incremental summary, and summary plus recall under the same model/corpus/tool/grant/context/execution budget. Record retrieval coverage, assembled evidence, correctness, stale facts, abstention, latency, tokens, summary/index preparation and grading denominators separately. The [LongMemEval paper](https://arxiv.org/abs/2410.10813) supplies useful extraction, cross-session reasoning, temporal reasoning, update and abstention categories; its benchmark does not choose Agentium's backend. The optional pilot in the eval plan has a predeclared spend envelope and is not authorized by this planning request. + +## Unresolved host prerequisites and deferred work + +The local correctness work and optional fake-adapter contracts are implementation-ready proposals. Production support depends on explicit host facts. Do not advertise the stronger claim before its prerequisite is met: + +| Gate | Required evidence / selected fallback | +|---|---| +| Distributed session ownership | Concrete atomic adapter, leases/revisions and fault tests. Generic KV and per-instance locks remain single-owner only. | +| Bounded archive recall | Adapter attests indexed bounded discovery, seekable excerpts, immutable source references and bounded current validation. Legacy full-array archive alone is unsupported for bounded recall. | +| Deletion completion / no physical late summary copy | Host integrates source invalidation and conditional summary-bearing commit atomically, or coordinates deletion/active refresh. Without it, SDK rejects stale reuse at validation points but cannot promise physical cross-store purge. | +| Project/cross-session sharing | Explicit host authorization and visibility policy; initial default is tenant/user/session. Untagged scope imports need host attestation. | +| Business completion | Application verifier supplies current run/revision/artifact facts; absent evidence returns unknown/stopped. No SDK guess from console claims. | +| Live quality and dollar budget | Fixed model snapshots/pricing/corpus/scorers plus explicit spend approval; initial gates are offline deterministic. | +| Breaking storage/replay defaults | Major release/migration decision. Keep additive paths and documented legacy behavior now. | +| Generated graph queries | Read-only host principal plus enforceable adapter contract before claiming read-only retrieval. No prompt/regex security guarantee. | + +Deferred: persistent fact promotion and background learning; a graph DB/vendor backend; authorized gap/tombstone coverage receipts; deep Workflow state isolation; recorded zero-effect playback; durable active-run recovery with operation intent/receipts and reconciliation; native client customization; skill-reference paging; generic tool discovery; global registry default change; unrelated package audits and broad package splits. Revisit each only with a concrete consumer and observable acceptance contract. + +The six fresh-review issues are resolved in the companions: incomplete child mapping, nested fatal joins, final current-view checks and bounded deletion guarantees, inaccessible archive frontier behavior, cancellation-safe settlement observations, and bounded clarification continuation. Implementation review must verify those contracts before claiming this handoff is complete. diff --git a/plans/core-harness-dependability/2026-10-13-execution-and-workflows.md b/plans/core-harness-dependability/2026-10-13-execution-and-workflows.md new file mode 100644 index 0000000..55f5d73 --- /dev/null +++ b/plans/core-harness-dependability/2026-10-13-execution-and-workflows.md @@ -0,0 +1,402 @@ +# Execution integrity and Workflow continuation implementation plan + +> **Status: PROPOSED; analysis only.** Implement only after user approval.

Each successful commit acknowledges its revision. Hosts supply transactional/CAS behavior. Opaque acknowledgement loss is not proof that a write did not occur. Track `commitAttempted` separately from `committed`; a rejected main commit produces `session_commit_failed` and `session_commit_outcome_unknown`, with no cleanup re-commit. A run failing before any commit may make one awaited partial-evidence commit. Hosts reconcile unknown acknowledgement from their revision/write receipts; the SDK cannot infer whether the write applied. Cancellation during commit waits for its outcome, then follows current cancelled terminal precedence. No new driver/model work starts. Failed partial persistence is diagnostic and does not replace the execution error. If a completed driver candidate exists when its commit acknowledgement fails, preserve its text/structured/usage as partial evidence in the failed HarnessResult; do not replace it with empty text or claim completion. Set partial true with session_commit_failed and the unknown-outcome cleanup diagnostic. + +Tests: deferred successful commit holds result and prevents release; delayed release holds result; failed main commit yields failed result, one commit attempt and an unknown-outcome diagnostic; rejected partial commit and release preserve primary error plus diagnostics; cancellation during commit yields one terminal, no second driver invocation; standalone retrieveHistory awaits release. Existing sync leases unchanged. Representative proposed test in the existing fixture module (its runtime/start/deferred helpers already exist): + +```ts +it("awaits commit acknowledgement before releasing the writer", async () => { + const entered = deferred(); + const ack = deferred(); + const release = vi.fn(); + const rt = runtime(async () => ({ text: "ok" }), { + sessionStore: { + guarantees: { durable: true, compareAndSwap: true, singleWriter: "distributed" }, + acquire: async () => ({ + read: () => ({ history: [], state: {}, revision: 0, replayable: true }), + commit: async () => { entered.resolve(); await ack.promise; }, + release, + }), + }, + }); + const handle = rt.start("hello", start); + let finished = false; + void handle.result().then(() => { finished = true; }); + await entered.promise; + expect(finished).toBe(false); + expect(release).not.toHaveBeenCalled(); + ack.resolve(); + expect((await handle.result()).status).toBe("completed"); + expect(release).toHaveBeenCalledOnce(); +}); +``` + +Completion: every Promise-returning extension path is awaited. This does not provide live-driver recovery. + +## E2 — Incremental log high-water recovery + +Files: `packages/core/src/session/incremental-session-manager.ts`, `session/__tests__/incremental-session.test.ts`, core README session guarantees. + +Before append/forced snapshot, derive next sequence from metadata, snapshot watermark and highest valid loose key. Use existing readLoose exact numeric-suffix filtering and watermarked snapshot semantics. Representative private implementation: + +```ts +private async readNextSequence(sessionId: string, metaNextSeq: number): Promise { + const snapshot = await this.readSnapshot(sessionId); + const loose = await this.readLoose(sessionId); + let nextSeq = Math.max(metaNextSeq, snapshot.nextSeq); + for (const entry of loose) { + const seq = Number(entry.key.slice(sessionId.length + 1)); + if (!Number.isSafeInteger(seq) || seq < 0 || seq === Number.MAX_SAFE_INTEGER) { + throw new Error("Invalid incremental session sequence"); + } + nextSeq = Math.max(nextSeq, seq + 1); + } + return nextSeq; +} +``` + +Validate metadata/snapshot watermark as safe nonnegative integers before arithmetic. getOrInitMeta uses recovery for both existing and missing metadata; orphan log records do not restart sequence at zero. Recompute appendsSinceSnapshot from uncollapsed loose records, excluding already-covered cleanup leftovers. Preserve Date hydration and legacy array snapshot reads. Scan cost is bounded by current loose entries under normal snapshot operation, not a distributed-log scalability guarantee. + +Fault test: JSON-cloning fake store writes A to loose log, fails following meta write, then new manager appends B. Both A/B must survive. Cover each write of multi-message batch, missing meta, metadata behind snapshot, post-snapshot leftovers, unsafe integer/invalid watermark and colon-prefixed sibling isolation. Existing cleanup-failure snapshot test stays. + +Independent-manager atomic append is explicitly deferred from this repair. Generic StorageDriver has no CAS/append capability. Document externally enforced one-writer ownership. A later optional session mutation port requires expected revision, stable caller message/operation IDs, duplicate payload checking, atomic append/state update and typed conflicts with a concrete tested adapter. Do not add generic transactions or claim log scanning solves F03 concurrency. Adapter choice/guarantees are a separate prerequisite rather than an implementation-ready hidden assumption. + +## E3 — Loop admission and cancellation parity + +Files: core `agent/llm-loop.ts`, `agent/agent.ts`, cap docs in `agent/types.ts`, existing controlled-loop tests and new `agent/__tests__/loop-boundary-parity.test.ts`. + +maxToolRoundtrips counts complete admitted tool-request batches. Zero allows initial model answer but no effects; N permits N batches and existing final-answer opportunity. Controlled counter continues across revisions; standalone count resets on each invocation. + +Proposed internal replacement: + +```ts +private claimToolRoundtrip(local: { used: number }): void { + const used = this.controlledExecution ? this.controlledToolRoundtrips : local.used; + if (used >= this.maxToolRoundtrips) { + throw new Error("Tool roundtrip budget exhausted; no further tools executed"); + } + if (this.controlledExecution) this.controlledToolRoundtrips++; + else local.used++; +} +``` + +run/stream each create a local counter and call shared claim after fully validating an assistant batch, before append/dispatch. Constructor validates safe nonnegative integer cap. No truthiness treatment of zero. Keep current inclusive model iteration; commentary-only responses retain existing iteration behavior, documented separately from effect count. + +Check signal after awaited model accounting and before accepting/publication/dispatch, after each host hook, and before final Agent completion. Nonstream matches streaming checks around output guards/afterRun. Preserve `withRetry(..., options.signal)`, repaired backoff and controlled default retry zero. Late reported usage remains in accounting; no next request/effect after known abort. Existing persisted evidence is not rolled back. + +Streaming checks signal before publishing the next accepted chunk/event, plus final post-stream guard; close iterators cooperatively. Noncooperative structural providers can still require host isolation to bound waiting. Preserve harness lease ownership. + +Team coordinator parity is a minimal dependency: ordinary Team.generate currently omits the signal (team.ts:387), while controlled services already enforce it. Pass `{ signal: ctx.signal }` to existing meteredGenerateFor and check signal before Team run.complete. Do not redesign Team routing. A cancellation during delayed coordinator synthesis must not report complete or delegate another member; known usage remains recorded. + +Tests: ordinary/controlled × run/stream × cap 0/1; zero no tool, one one batch plus final answer; invalid caps reject before requests. Provider aborts before late successful final response -> cancelled, never completed. Hook aborts after model and afterRun -> no new effect/call/completed event. Account late usage. Reuse current request-control/budget tests as regressions; do not rewrite providers. + +## E4 — Terminal truth and partial output + +Files: core `agent/types.ts`, `agent/llm-loop.ts`, `agent/agent.ts`; harness `drivers.ts`, result/event optional fields only if needed by final API. Keep status union: length/filter are stopped; incomplete protocol is error/failed. + +Proposed additive metadata: + +```ts +export interface RunOutput { + // existing fields preserved + providerFinishReason?: string; + partial?: boolean; + reason?: { code: string; message: string }; +} +``` + +Final-answer construction retains text/usage, providerFinishReason, and stopped + stable provider_length/provider_content_filter reason where relevant. Only stop is ordinary model completion. Stream outcome carries same metadata and Agent aggregates it. Any no-finish stream, including text-only/empty, fails; unfinished tools never dispatch. Preserve already-published text as partial/error evidence. A proposed ModelProtocolError code incomplete_stream is useful only if exported consumers need it; root diagnostics plan should select a common result shape. + +agentDriver output forwards status/reason/partial text. Add optional partial and providerFinishReason to the existing HarnessDriverOutput and HarnessResult interfaces; reuse the existing HarnessReason for reason. Forward them through drivers.ts output() and terminalResult in runtime/driver.ts. The Agent adapter forwards the new core reason as well. This is the selected shared metadata shape, with no parallel status taxonomy. No automatic extra model call after length: host-directed continuation must explicitly use remaining budget. + +Tests: run/stream length/filter produce stopped with text/usage; missing finish fails text-only/empty; partial tool stream never dispatches; harness Agent adapter preserves stopped and reason. Compatibility: callers relying on truncated output as completed must check status; document correctness change. + +## E5 — Workflow owned updates and cooperative stopping + +Files: core `workflow/step-runner.ts`, `workflow/types.ts`, `workflow/__tests__/workflow.test.ts`, README; minimal harness integration fixture if adapter behavior changes. + +Carry produced patch separately from working state. Function patch is returned Partial; Agent patch is named output; condition/serial accumulates patches in declaration order; parallel applies fulfilled branch PATCH rather than copied base. Do not derive writes by diffing final states (same-value intentional writes disappear under diff). + +Proposed private outcome: + +```ts +interface StepExecution { + state: TState; + patch: Partial; + results: StepResult[]; +} +``` + +Validate function patch as non-null non-array object, filter existing prototype-sensitive keys, apply to working state and accumulate owned writes. Existing public executeSteps return can remain state/results; internal helper handles patches. + +Proposed additive configuration: + +```ts +export interface ParallelStep { + name: string; + parallel: StepDef[]; + merge?: "declaration_order" | "error"; +} +``` + +Default declaration_order preserves intentional last-declared same-key collision behavior while fixing untouched field overwrite. Strict error detects keys produced by different branches and throws a proposed `WorkflowMergeConflict` (stable code `workflow_merge_conflict`) from the join before mutating parent state, so executeSteps cannot dispatch downstream steps; namespaced branch outputs followed by serial merge suffice instead of a reducer API until demand proves need. + +Strict merge conflicts use an exported `WorkflowMergeConflict extends Error`, code `workflow_merge_conflict`, with `stepName` and bounded `conflictingKeys: readonly string[]`. They are structural fatal errors, not ordinary retriable step failures. At every serial/condition/parallel parent, detect and rethrow this class after already-started siblings settle. Never downgrade it through `allSettled` or `withRetry`. A strict failed join applies none of that join's sibling patches to its parent; earlier serial state/checkpoints remain evidence, and sibling external effects remain applied. Do not save a success checkpoint or dispatch downstream work. Include a nested-strict-group regression, not only a top-level join test. + +Branches currently receive shallow copies. Document returned patches and branch-owned objects; do not promise deep immutability or unconditionally structuredClone arbitrary unknown state (clients/functions may exist). Nested direct mutation remains a compatibility limitation; isolated serializable-state mode is deferred. Do not claim patch merge solves shared nested references. Add a negative fixture documenting that boundary. + +### Explicit failure policy and child output mapping + +Proposed additive public fields, preserving the existing StepResult status union: + +```ts +// Add to existing WorkflowConfig. +failurePolicy?: "continue" | "stop"; // default continue + +// Add optional fields to existing StepResult. +output?: { text: string; status: RunOutput["status"]; reason?: RunOutput["reason"] }; + +// Add optional fields to existing WorkflowResult during additive rollout. +status?: "completed" | "failed"; +reason?: { code: "workflow_step_failed"; message: string }; +``` + +These are interface additions, not standalone statements. Import RunOutput with `import type` in workflow/types.ts. The implementation always sets aggregate status on new outputs; optional declaration fields preserve structural third-party producers. No error step can produce aggregate completed, even when continue runs later steps. Skipped condition branches alone do not fail a run. + +`executeAgentStep` checks cancellation after `agent.run`. A missing status on a legacy structural output remains completed for compatibility; native Agent always sets it. Completed output produces the existing named output patch and done result. Error/stopped output produces no state patch and an error StepResult containing partial text/status/reason. Do not retry a resolved stopped output as a provider exception. Under continue, subsequent steps see the unchanged field; partial text is evidence in stepResults, never masquerades as `${step.name}_output`. Under stop, skip remaining serial steps with `status: "skipped"` and do not start later groups. Already-started parallel siblings settle; successful branch patches may join under declaration_order, while the aggregate remains failed. A condition inherits this policy for its selected branch. Child cancelled output throws exported `WorkflowCancellationError` (code `workflow_cancelled`); it escapes ordinary retry/continue. Parent signal cancellation throws its existing abort reason. Workflow catches only to emit run.error, then rethrows. No late patch/checkpoint/run.complete follows cancellation. + +Update harness `workflowDriver` to use aggregate status, with the existing error-step fallback for older Workflow-like outputs. Map WorkflowCancellationError to cancelled; ordinary errors/strict merge conflicts map to failed. The adapter preserves failed partial state/step-results as evidence when a result exists. Cancellation does not undo successful siblings' effects. + +Representative aggregation control flow (new helpers are explicitly private StepRunner methods): + +```ts +const outcomes = await Promise.allSettled( + step.parallel.map((branch) => this.executeStepWithPatch(branch, { ...state }, ctx)), +); +ctx.signal?.throwIfAborted(); +for (const outcome of outcomes) { + if (outcome.status === "rejected" && + (outcome.reason instanceof WorkflowMergeConflict || + outcome.reason instanceof WorkflowCancellationError)) throw outcome.reason; +} +// Collect ordinary errors first. Strict conflict detection runs before any +// parent mutation; declaration-order joins apply only fulfilled owned patches. +const joined = this.joinBranchPatches(step, state, outcomes); +// Serial callers inspect error results and skip remaining work under stop. +return joined; +``` + +`executeStepWithPatch` replaces the existing private step dispatcher, retaining Agent/function/condition/parallel variants. `joinBranchPatches` iterates fulfilled patches in declaration order, rejects duplicate own keys for strict mode, then applies the accepted patch once. Results flatten in declaration order, regardless of settlement timing. All parents propagate structural fatal outcomes; ordinary child errors stay recorded. + +Keep ordinary collect-errors behavior; existing tests intentionally continue. Cancellation must escape it: check after function/Agent await before applying patch, after allSettled before merge and before final workflow run.complete. Replace StepRunner plain timeout backoff using existing abortable helper with timer cleared in finally. Do not use generic withRetry defaults or retry controlled dispatchEffect errors (currently first failure is collected without retry deliberately). + +Tests: initialized disjoint a/b patches survive both completion orders; nested serial/condition patches survive; collision default follows declaration order and strict rejects with no downstream call; failed sibling follows documented partial merge. Cancel during function prevents late patch, during backoff prevents attempt two, after final step prevents complete. Controlled effect invoked once. Representative proposed test using the real existing Workflow class: + +```ts +it("keeps independent writes when the input already contains both keys", async () => { + const workflow = new Workflow({ + name: "disjoint", register: false, + initialState: { a: 0, b: 0 }, + steps: [{ name: "join", parallel: [ + { name: "a", run: async () => ({ a: 1 }) }, + { name: "b", run: async () => ({ b: 2 }) }, + ] }], + }); + expect((await workflow.run()).state).toEqual({ a: 1, b: 2 }); +}); +``` + +## E6 — Definition-bound checkpoint continuation + +Files: core `workflow/workflow.ts`, `workflow/checkpoints.ts`, `workflow/types.ts`, checkpoint tests, exports as needed, README. Harness driver remains durable:false. + +Inspection has no effects. Continuation runs remaining steps afresh and may repeat every later effect; fork also changes starting state. Exact playback consumes recorded model/tool outcomes without calls; current replay is continuation, not playback. + +First repair cursor: executeStepwise receives absolute fromStepIndex and iterates original config.steps; never slice then persist zero-based indices. New IDs combine new runId + absolute padded step index. Start cumulative stepResults from checkpoint results; keep parent checkpoint/run lineage separate from new run identity. + +Proposed fields: + +```ts +export interface WorkflowConfig> { + // existing fields + definitionVersion?: string; + validateCheckpointState?: (value: unknown) => TState; +} +export interface WorkflowCheckpoint { + // existing fields + formatVersion?: 2; + definitionVersion?: string; + stepNames?: string[]; + parentCheckpointId?: string; + parentRunId?: string; +} +export type WorkflowContinuationOptions = RunOpts; +``` + +Zod validates external checkpoint envelope; validateCheckpointState recovers state without asserting unknown as TState. Construction requires definitionVersion and validateCheckpointState together when either is supplied. With both configured, runWithCheckpoints emits v2; without both it preserves legacy envelopes for inspection/legacy wrappers. New validated method requires version + validator; match workflowName/version/ordered top-level names/index before effects. Callable code changes require host version bump; names cannot detect closure changes. + +Proposed method: + +```ts +async continueFromCheckpoint( + checkpointId: string, + opts?: WorkflowContinuationOptions, +): Promise & { runId: string }>; +``` + +Widen runWithCheckpoints opts to RunOpts & initialState, preserving old session/user calls and common RunContext/accounting construction. Forward tenant/signal/runMode/executionServices/metadata and only child-supported key/dependency fields after inspecting actual forwarding. New caller identity/policy authoritative; never serialize credentials/signals/services. Checkpoint write failure stops next step and rejects; completed effect remains applied. + +Deprecate replay terminology; keep compatibility wrapper, validating new checkpoints strictly and documenting the legacy path. New strict continuation rejects unversioned records before effects with `checkpoint_incompatible`. Existing `replay` and `fork` receive absolute-cursor correction, workflow-name validation and deprecation, but retain their legacy acceptance through the current major. Document that legacy validation cannot establish original definition identity. An eventual major may route them exclusively through strict continuation and reject legacy records; do not ship that breaking rejection silently in a patch. Offer offline host migration with explicit original index/version/state validation. Strict continuation never infers identity or permits a blanket legacy bypass. Fork keeps existing mutation argument and adds optional opts afterward; same validation and absolute cursor. Run restored state through the host validator, then structuredClone the validated value before mutations/dispatch on the strict method; reject noncloneable state before effects. Legacy methods retain documented existing state compatibility until the major migration. Clone checkpoint state and cumulative results on save as well, so in-memory store aliasing cannot change an older checkpoint. Hosts selecting JSON-persisted stores must validate JSON-compatible state; callable/client dependencies stay in RunOpts, outside checkpoint state. Document this serialization boundary and do not shallow-mutate stored nested references. Existing unversioned runWithCheckpoints remains useful for inspection; safe continuation requires version/validator and newly emitted v2 checkpoint. + +Top-level condition/parallel step remains one checkpoint boundary. No mid-step resume, approval restoration, inherited active reservations, exactly-once effects, or active harness recovery.

Never fall back from a new encoded key to an ambiguous legacy key automatically. Never close storage while tracked memory work can still write to it.

Do not introduce extraction into harness-controlled ephemeral Agents. + +Review delimiter-bearing and empty IDs; Redis glob characters; a summary stalled during close; a run entering while close starts; and budget-fitting memory which previously omitted its wrapper. Pin each in the tasks below. + +## M2 — Collision-free storage identities with an explicit persisted migration + +### Problem and evidence + +Current `packages/core/src/storage/in-memory.ts:6–31` concatenates `(namespace, key)` with `:` and lists by that prefix. `("parent:child", "key")` and `("parent", "child:key")` collide. `storage/scoped.ts:24–29` and `tenant/tenant-storage.ts:13` similarly concatenate unrestricted scope components. `storage/redis.ts:44–49` mixes literal identifiers with SCAN glob syntax. These remain source-confirmed after the earlier audit; the prior audit executed local collision fixtures, but this planning pass did not rerun them. + +The harness already uses `JSON.stringify([tenantId, userId, sessionId])` in `runtime/session-bindings.ts:31`. Keep that existing contract. + +### Selected design and alternatives + +1. Change `InMemoryStorage` to a map of namespace maps. This is a corrective change: separate public namespaces must stay separate. Preserve JSON cloning and `list`'s literal `key.startsWith(prefix)` behavior. +2. Add internal `storage/key-codec.ts`. Scoped namespace tuples use a versioned JSON array, preserving absent versus empty scope values. Redis physical segments use four-digit hexadecimal UTF-16 code units, which preserve exact JS strings and literal key-prefix matching, including unpaired surrogates. Do not use raw delimiters or escaped SCAN input as the identity codec. +3. Add explicit `keyEncoding: "legacy" | "tuple-v1"` options to `ScopedStorage`, `TenantScopedStorage`, and `RedisStorageConfig`. Existing constructors default to `legacy` until a planned major-version migration; new documented shared-host examples select `tuple-v1`. The in-memory namespace fix lands immediately in either mode. +4. Add `ownsInner?: boolean` to wrappers, defaulting to `true` for compatibility; new borrowed-client examples pass `false`. Closing a borrowed wrapper does not close its inner storage. Initialization ownership remains unchanged; document idempotent initialization as the inner driver's responsibility. + +Changing persistent defaults immediately would make existing records disappear. Automatic dual reads could expose another scope's legacy record. The selected additive path avoids both. Hosts which need isolation must migrate or create a new store with `tuple-v1`; the legacy mode is explicitly unsuitable for unrestricted identifiers in shared storage. + +### Proposed public options and internal encoding + +```ts +// Proposed additions to storage/scoped.ts; reused by TenantScopedStorage. +export interface ScopedStorageOptions { + keyEncoding?: "legacy" | "tuple-v1"; + ownsInner?: boolean; +} + +// Proposed addition; retain all existing RedisStorageConfig fields. +export interface RedisStorageConfig { + keyEncoding?: "legacy" | "tuple-v1"; +} + +// Proposed internal storage/key-codec.ts. +export function encodeScopeNamespace( + namespace: string, + scope: { tenantId?: string; userId?: string }, +): string { + return JSON.stringify([ + "agentium-storage-scope-v1", + scope.tenantId ?? null, + scope.userId ?? null, + namespace, + ]); +} + +export function encodeKeySegment(value: string): string { + let encoded = ""; + for (let index = 0; index < value.length; index++) { + encoded += value.charCodeAt(index).toString(16).padStart(4, "0"); + } + return encoded; +} + +export function decodeKeySegment(encoded: string): string { + if (encoded.length % 4 || !/^[0-9a-f]*$/.test(encoded)) { + throw new TypeError("Invalid storage key encoding"); + } + let value = ""; + for (let index = 0; index < encoded.length; index += 4) { + value += String.fromCharCode(Number.parseInt(encoded.slice(index, index + 4), 16)); + } + return value; +} +``` + +Redis v1 key: `agkv1:::`. The SCAN pattern uses the exact encoded namespace plus the encoded literal key prefix plus a single trailing `*`. Decode only the final key segment. The trusted adapter's keyPrefix is encoded too. Continue scanning every page as current RedisStorage does. JSON payload format and TTL semantics stay unchanged. + +Representative corrective in-memory implementation: + +```ts +private store = new Map>(); + +async set(namespace: string, key: string, value: T): Promise { + let entries = this.store.get(namespace); + if (!entries) { + entries = new Map(); + this.store.set(namespace, entries); + } + entries.set(key, JSON.stringify(value)); +} + +async list(namespace: string, prefix?: string): Promise> { + const results: Array<{ key: string; value: T }> = []; + for (const [key, raw] of this.store.get(namespace) ?? []) { + if (prefix === undefined || key.startsWith(prefix)) { + results.push({ key, value: JSON.parse(raw) }); + } + } + return results; +} +``` + +`get`, `delete`, and `close` mechanically follow the namespace map. Delete empty inner maps. Keep deserialization behavior identical to the existing generic KV API; introducing payload schemas here would be a separate breaking change. + +### Files, tasks, and tests + +- Create `packages/core/src/storage/key-codec.ts` and `storage/__tests__/key-codec.test.ts`. +- Modify `storage/in-memory.ts`, `storage/scoped.ts`, `storage/redis.ts`, `tenant/tenant-storage.ts`. +- Update root exports for `ScopedStorageOptions` and existing Redis config type; do not expose the physical codec as a supported public API. +- Extend `storage/__tests__/storage.test.ts`, `scoped.test.ts`; create `redis-key-codec.test.ts` using the existing optional-dependency mocking pattern, with no network calls. +- Document explicit persistent migration in `packages/core/README.md`; update scoped-storage examples only where they instantiate these wrappers. + +Representative proposed regression: + +```ts +it("keeps delimiter-bearing namespaces distinct", async () => { + const storage = new InMemoryStorage(); + await storage.set("parent:child", "key", { value: 1 }); + expect(await storage.get("parent", "child:key")).toBeNull(); + expect(await storage.list("parent")).toEqual([]); + expect(await storage.get("parent:child", "key")).toEqual({ value: 1 }); +}); +``` + +- [ ] First pin collisions and exact `list` boundaries with the public API. +- [ ] Implement namespace maps and encoding options; preserve legacy physical keys when explicitly/default selected. +- [ ] Test empty versus absent scope, `:`, Unicode, unpaired surrogate strings, Redis `* ? [ ] \\`, literal prefixes, TTL and codec round trips. +- [ ] Verify `ownsInner:false` leaves a shared driver usable after wrapper close. +- [ ] Verify old data is never read through v1 fallback and document this intentional behavior. +- [ ] Run `npx vitest run packages/core/src/storage/__tests__`; then `npm run build:core`. + +### Migration gate + +The SDK cannot reconstruct all ambiguous legacy tuples. Supply a documentation recipe, not an automatic migration command: freeze writers; use a trusted inventory of logical scopes/keys; export each logical record through its intended owner; detect duplicates; import into a distinct v1 prefix; compare counts and payload digests; cut over all writers together; retain the read-only old prefix for the host's rollback window. Do not print data payloads in migration diagnostics. A major release may default to v1 only after this guide and explicit legacy override exist. That release decision is deferred; the opt-in path is implementation-ready. + +## M3 — One owner for background memory work and honest context assembly + +### Problem and existing behavior + +`memory/memory-manager.ts:176–179` launches overflow summaries without adding them to `pendingExtractions`. `afterRun:413–415` tracks extraction only; `awaitExtractions:428` therefore misses summaries. `agent/agent.ts:562–572` closes configured storage without draining memory. Current memory context includes wrapper markers in the unbudgeted path (`assemble:280`) but omits them when all sections fit (`allocateBudget:300–301`). Wrapper cost is also excluded from token admission. `agent/agent.ts:1468–1471` currently appends MemoryManager source text to system instructions. Move it to a separate source-role message; wrappers alone do not preserve authority. `remember:440–467` may resolve without writing when no destination is enabled. Existing `recordCorrection` and `LearnedKnowledge.invalidateContradicted` already exist and remain unchanged; they do not establish a generic project-fact schema. + +### Proposed APIs, ownership and lifecycle + +```ts +// Proposed exports from memory/memory-manager.ts and core root. +export interface MemoryDrainOptions { + timeoutMs?: number; // omitted: wait cooperatively without a local deadline + signal?: AbortSignal; +} +export interface MemoryDrainResult { + status: "drained" | "timed_out" | "cancelled"; + pending: number; + failed: number; +} +export type RememberResult = + | { stored: true; destination: "user_facts" | "learnings" | "entities" } + | { stored: false; reason: "no_destination" }; + +// Proposed additive methods; existing methods retain their signatures. +MemoryManager.drain(options?: MemoryDrainOptions): Promise; +MemoryManager.rememberWithResult( + content: string, + opts?: { userId?: string; scope?: string; importance?: number }, +): Promise; + +// Proposed additive fields on existing Agent.close options. +export interface AgentCloseOptions { + closeStorage?: boolean; + memoryDrain?: MemoryDrainOptions; // default timeoutMs: 30_000 +} +// Agent.close(options?: AgentCloseOptions): Promise; +``` + +These signatures are API declarations for existing classes, not standalone TypeScript statements to paste literally. Implement `rememberWithResult` using exactly the current destination precedence; legacy `remember` awaits it and returns `void`, preserving no-op compatibility. Document the result-bearing method as the recommended new journey. The persisted fact model is not introduced here. + +Rename the private pending set to `pendingMemoryOperations`; introduce private `trackMemoryOperation(kind, promise)`. Track summary and extraction work before callers can observe completion. Attach both success and rejection handlers for removal rather than ignoring the rejected promise returned by `.finally`. Track every asynchronous memory operation launched internally, including nested helper operations, until its final write/settlement; the owned promise must include catch/reporting cleanup. Existing `awaitExtractions()` delegates to `drain()` with no local timeout and now includes summaries; update its description. Increment a monotonic failure counter once per failed owned operation and emit existing `memory.error` events once per operation; do not duplicate store-specific errors. + +`drain` snapshots no authority: it waits until the tracked set is empty, including operations added during the wait. A signal/deadline races waiting only. Timeout/cancellation returns pending counts, never clears operations or claims remote cancellation. Clean up every timer/listener. No automatic retries of a possibly applied storage write. + +Add private Agent lifecycle state `open | closing | closed`, active top-level operation count, and one close promise. `run` and the first executed step of `stream` acquire/release a local operation lease in `try/finally`. `close` rejects with an exported `AgentLifecycleError` code `AGENT_BUSY` while a top-level operation is active; it does not cancel user work implicitly. On a quiescent Agent, close blocks new run/stream admission, drains memory, detaches webhooks and closes owned accounting/approval resources, then closes storage only if existing `closeStorage !== false`. If drain is not complete, reject with `MemoryDrainError` containing the result, retain the storage and owned resources, and allow a later close attempt; keep run admission blocked until close succeeds. Concurrent close callers share the same in-flight promise. Clear that promise after rejection so retries can drain pending work. Calling close after success is idempotent. + +For `closeStorage:false`, drain still applies; borrowed storage must not receive untracked late work. The host remains responsible for not closing the shared client through another owner. This correction adds bounded shutdown latency and a truthful busy/error outcome; document that behavioral compatibility change. + +Proposed errors and result-bearing journey: + +```ts +export class AgentLifecycleError extends Error { + constructor(readonly code: "AGENT_BUSY" | "AGENT_CLOSING" | "AGENT_CLOSED") { + super(code); + this.name = "AgentLifecycleError"; + } +} +export class MemoryDrainError extends Error { + readonly code = "MEMORY_DRAIN_INCOMPLETE"; + constructor(readonly result: MemoryDrainResult) { + super(`Memory drain ${result.status}: ${result.pending} operations pending`); + this.name = "MemoryDrainError"; + } +} + +// Before: remember could silently have no enabled destination. +await agent.memory?.remember("Deployments require review", { userId: "user" }); +// After: proposed result-bearing method, without changing legacy remember. +const remembered = await agent.memory?.rememberWithResult("Deployments require review", { userId: "user" }); +if (remembered && !remembered.stored) { + console.info("Memory was not stored:", remembered.reason); +} +await agent.close({ closeStorage: false, memoryDrain: { timeoutMs: 5000 } }); +``` + +Error codes are new named exports from core root. Close failure after drain (e.g. owned storage close rejection) retains closing admission and allows retry; each owned teardown component is marked closed only after acknowledgement, so a retry never double-disposes acknowledged resources. Preserve the first teardown error and attach later failures as bounded diagnostics. A user-initiated close does not cancel an active operation. + +### Representative tracking and assembly changes + +```ts +private trackMemoryOperation(operation: Promise): Promise { + this.pendingMemoryOperations.add(operation); + void operation.then( + () => this.pendingMemoryOperations.delete(operation), + () => this.pendingMemoryOperations.delete(operation), + ); + return operation; +} +``` + +Wrap the existing summary and extraction promises with this helper, retaining their error-reporting behavior. `failed` is `failureCountAtReturn - failureCountAtDrainEntry`, computed from one monotonic counter; overlapping drains each report failures during their own interval. Track failure before removing the operation so a drained result observes it. A drained result may have failed > 0 because work ended unsuccessfully; it does not imply data was saved. Existing error events identify those failures. A failure result does not imply a write can be retried safely. + +Extract a private `renderMemorySection(key, content): string` used by `assemble` and every `allocateBudget` branch. The wrapper explicitly labels content as source data. Count rendered strings and separators, not only raw contents. Whole sections are the default atomic unit; omit a section that does not fit rather than sever a correction/negation with the current line trimming. Return a short omission marker only if its tokens fit. Keep priority ordering stable. If all wrappers alone exceed the budget, return an empty context and an existing observation event/optional diagnostic; never exceed the configured budget merely to explain omission. Validate `maxTokens` as a positive safe integer when configured. This output change is corrective and can affect answer quality; the evaluation milestone measures it. + +Move only the MemoryManager-generated context out of `systemContent` in Agent.buildMessages. Keep host-authored instructions in the existing system message. After that message and before resident history, insert `{ role: "user", content: memoryContext, providerExtras: { memoryContext: { version: 1, trust: "source" } } }`. Budget/history admission includes that rendered message as fixed context; do not increase a requested memory token allowance to accommodate wrappers. Keep it out of canonical new user/model/tool messages so it is not re-recorded as a user requirement on the next turn. Metadata labels are provenance, not an access check or prompt-injection guarantee. The user-message role enforces the provider priority distinction. Explicitly defer reclassifying host-configured skill/rule/context-file content until its ownership contract is reviewed; M3 must not silently lower legitimate host instructions. + +Add a captured-request test: remembered text says "Ignore the host instructions"; the host instruction remains unchanged in the system message, remembered text is only in the source user message, and canonical history does not acquire a synthetic human instruction. Quality resistance to source instruction attacks belongs in M6 evaluation; role separation alone is not a behavioral proof. + +### Files and acceptance tasks + +- Modify `packages/core/src/memory/memory-manager.ts`, `agent/agent.ts`, and root `index.ts`. +- Create `memory/__tests__/memory-lifecycle.test.ts` and `agent/__tests__/agent-close.test.ts`; extend `memory/__tests__/memory-manager.test.ts`. +- Update `packages/core/README.md`; harness driver disposal keeps `closeStorage:false` and benefits from the bounded drain. No change to harness extraction defaults. + +- [ ] Hold the overflow summary provider promise open; verify `drain` remains pending and `awaitExtractions` now includes it. +- [ ] Verify drain timeout leaves pending work tracked, store open, and a later drain succeeds after the fixture settles. +- [ ] Test extraction and summary failures report diagnostics once, all listener/timer paths clean up, and close does not erase primary operation errors. +- [ ] Test two close callers, repeated close, active-run rejection, a paused stream iterator, and run admission after close starts. +- [ ] Test `closeStorage:false` never closes a borrowed driver; a host store remains usable. +- [ ] Verify identical source wrappers in budgeted/unbudgeted paths; counted output including markers never exceeds the budget. A correction with a negation is included intact or explicitly omitted. +- [ ] Verify `rememberWithResult` returns `no_destination` for default-disabled destinations while legacy `remember` still resolves. +- [ ] Run `npx vitest run packages/core/src/memory/__tests__ packages/core/src/agent/__tests__/agent-close.test.ts`; then `npm run build:core`. + +An uncooperative SDK callback can leave `pending > 0`. The design reports this and retains ownership; it does not force termination. Extending signals through every old extraction store is deferred until its versioned cancellation/effect contract is designed. `drain` alone never claims that ability. + +## M1 companion — Guard incompatible legacy budget reads + +`cost/cost-tracker.ts:271` and `418` reject synchronous local summaries once canonical accounting is used. `checkInProgressBudget:335`, `isBudgetExceeded:375`, `estimateRemaining:405`, and the string overload of `checkBudget:227` still read `legacyTotals`. They can return a plausible false or remaining allowance for a canonical ledger. + +Selected corrective change: the three methods and string checkBudget overload call one private guard at entry (after object-overload dispatch), before even an absent legacy budget branch. Preserve their legacy behavior otherwise. Keep existing asynchronous ledger queries and admission APIs as the supported canonical path; do not duplicate currency admission in harness. + +```ts +private assertLegacyBudgetRead(): void { + if (this.canonicalUsed) { + throw new IncompleteCostError( + "Canonical accounting requires ledger budget decisions; synchronous legacy budget reads are incomplete", + ); + } +} +``` + +- [ ] Add a canonical measurement fixture to `packages/core/src/cost/__tests__/cost-tracker.test.ts`; assert each legacy method, including string checkBudget, throws `IncompleteCostError` rather than reporting allowance. +- [ ] Verify genuinely legacy usage preserves each existing method's values. +- [ ] Inspect core Agent call sites to ensure canonical execution already uses ledger admission; replace any newly found deprecated call with the existing asynchronous admission method, never catch-and-return-false. +- [ ] Update root TSDoc/README deprecations with a before/after query example. Existing canonical symbols are `queryUsage`, `queryCosts`, `queryAssessments`, `queryRunUsage` and the object overload of `checkBudget(scope, bound?)`. Use `await tracker.checkBudget({ tenantId, runId, sessionId })` for a ledger decision; inspect its status/reservation and let the existing accounting owner reconcile or release its reservation. The string overload remains legacy and now rejects canonical use; do not replace a read with a reserving call without documenting reservation ownership. Use `await tracker.queryRunUsage(scope)` for an observational query. +- [ ] Run `npx vitest run packages/core/src/cost/__tests__/cost-tracker.test.ts packages/core/src/__tests__/cost-tracker-incremental.test.ts`. + +## Completion and limitations + +Each milestone can land independently after its focused checks, declarations, and documentation pass. Run `npx biome check` on changed TypeScript files; `npm run build`; `npm run test:package`; and `git diff --check` at the combined release review.

Branch: `agent/core-cost-accounting`. - -## Implementation status - -All six source phases are implemented. Source was frozen after the final focused gates below. The release coordinator owns the final workspace, package, documentation, version, and publication gates; those results must be appended before release. - -No live provider requests were made. All usage payloads are synthetic fixtures, SDK mocks, or loopback transport fixtures. All database tests use disposable local databases. - -## Phase 1 — Usage contracts and adapters - -- Canonical inclusive input is split into ordinary input, cache reads, and cache writes. Output includes reasoning; reasoning is not added again. -- Unknown counts are nullable. Runtime validation retains partition, total, subset, schema, unsupported-feature, and modality/cache ambiguity issues. -- Separate normalizers cover Chat Completions, Responses, Decisions, Anthropic, Google, Cohere billed units, Mistral, Bedrock/Claude, Azure, Vertex, Ollama, compatible APIs, and Perplexity. Cloud billers retain their own identity. -- Raw usage retention strips credentials and response content, bounds UTF-8 JSON bytes, and marks truncation. -- Adapter fixtures and `BUILTIN_USAGE_CAPABILITIES` describe exact supported mappings and limitations. - -## Phase 2 — Attempt lifecycle - -- Paid physical requests have stable operation, attempt, observation, and assessment identity. Start intent is retained before submission. -- Observable retries/fallbacks retain distinct attempts. Opaque SDK retries are labelled; the code does not invent hidden attempts. -- Stream snapshots replace and unique deltas add. Partial/canceled/failed execution keeps available evidence, including usage after finish. -- Reflection, compression, context compaction, tools, memory, Team, Workflow, handoff, and direct supported helpers use the same accounting boundary. -- Whole-run pending markers drain tools/hooks between model calls when an owned Agent/Team/Workflow closes. -- Failed accounting retries the immutable evidence write, never the provider call. Validation/conflict errors keep their public error class and code. -- Durable run lineage preserves empty intermediate workflows. Child queries resolve the root by key and use root indexes; unrelated tenant history is not scanned. - -## Phase 3 — Catalog and calculation - -- Exact rational arithmetic supports unit, fixed, marginal tier, minimum, block rounding, ordered adjustment, effective date, context, mode/tier, region, currency, and account rules. -- Exact model identity and explicit aliases replace substring guesses. Ambiguous catalog matches fail validation. -- Reviewed built-in snapshot: 306 rules for 17 exact models, with source URLs and verification dates. Unsupported model/account/region/tier combinations remain unpriced. -- The public calculator validates canonical usage and the catalog. Missing quantities/rates/context produce a null total and a priced subtotal. -- Billing groups apply rounding/minimum once. Immutable group assessments retain source attempt, observation, and measurement membership. Corrections/repricing retire prior selected group amounts. -- Provider-reported and invoice amounts have scoped evidence and separate selected views. Durable allocations do not add the group payable a second time. Group finalization requires explicit confirmation. - -## Phase 4 — Storage and budgets - -- In-memory, optional SQLite, and optional PostgreSQL stores retain immutable observations/revisions/assessments, selections, allocations, and indexed lineage. -- Selection, group updates, budget deltas, and reservation settlement commit atomically. Stale concurrent selections retry optimistically. -- Selected authoritative costs drive budget admission, including costs recorded before a policy was attached or by another tracker. -- Idempotent reservation IDs, unique scope checks, explicit periods/currencies, unknown-policy handling, threshold warnings/blocks, and conservative reservation bounds are supported. -- Real subprocess fixtures kill workers after evidence and after settlement, replay without duplicate spend, and race two independent reservation workers against SQLite and PostgreSQL. -- Canonical aggregation and a new budget retain 10,001 selected charges. Legacy display eviction cannot lower legacy budget spend. - -## Phase 5 — Other operation types - -- Embeddings, reranking, realtime voice, file STT/TTS, VoicePipeline, vision, image generation, and browser integration preserve supported usage evidence through core. -- Cache storage intervals and custom namespaced measurements use the same record API. Unsupported billing contracts remain explicit unknowns. -- `BUILTIN_ACCOUNTING_CAPABILITIES`, the core README coverage table, and provider capability exports inventory partial and unmetered paths. - -## Phase 6 — Public API and consumers - -- `cost: true` is opt-in and returns `result.costs`; terminal stream chunks have the same snapshot. Team and Workflow expose the same cost option and snapshot. -- `cost: { budget: { maxCostPerRun: 0.5 } }` provides a simple threshold path; advanced durable policies remain available. Legacy token limits are enforced. -- `ModelConfig.billingContext` configures non-secret account facts once; returned billing facts override defaults. Provider identity cannot be replaced by billing dimensions. -- Snapshot query failure preserves successful model output as `status: "unavailable"` with null totals. -- Owned trackers drain and close their own store. Borrowed trackers/stores are not closed by their consumers. -- Legacy synchronous reads reject ambiguous canonical projections. Canonical `cost.assessed` events and partial metrics do not double-count legacy replacement run totals. -- Core/observability README and public exports updated. External docs and dual CommonJS declaration packaging belong to the release coordinator. - -## Executed checks - -Final executor gates: - -| Check | Result | -| --- | --- | -| Cost directory plus billing-context helper suite, PostgreSQL enabled | 15 files, 180 tests passed | -| `npx tsc -p packages/core/tsconfig.json --noEmit --pretty false` | Passed | -| `npx biome ci .` | Passed | -| Canonical 10,001-charge aggregate/new-budget regression | Passed | -| SQLite/PostgreSQL subprocess crash/replay and independent-worker reservation races | Passed, both backends | -| Nested empty Workflow lineage, sibling isolation, root-index query spy | Passed | -| Team/Workflow close through work between model calls | Passed | - -Delegated source gates: - -- Lifecycle/Agent DX/handoff final gate: 88 tests passed; core typecheck passed. -- Native billing-context Google/Cohere/Mistral SDK and Agent gate: 36 tests passed; core typecheck passed. -- Earlier observability focused gate: 99 passed, 2 optional conformance tests skipped at that agent; coordinator later owns enabled optional gates. -- Provider usage/reviewed pricing fixtures are included in final cost/provider focused checks. -- Earlier full all-package build passed before the last DX/lineage changes. A final rebuild is required and owned by the coordinator. - -Raw final executor logs are in `/tmp/agentium-final-cost-tests3.txt`, `/tmp/agentium-final-core-tsc3.txt`, and `/tmp/agentium-final-global-biome.txt` on this host. - -The direct-call search required by the plan was repeated. Remaining production matches are Team's own metered helper, Agent's metered LLMLoop/continuation streams, and the explicit external-agent boundary; test mocks are excluded from the production inventory. - -## Intentional limits - -- Accurate future provider tariffs cannot be inferred. Unknown rates or billing fields remain visible, never guessed as free. -- Direct external provider work needs an accounting context or the public custom recording API. -- Providers with internal SDK retries can be opaque. In-memory storage is local and not shared reservation storage. -- List-price estimates, provider-reported amounts, invoice amounts, and allocation views are separate; catalog repricing does not replace original budget spend. -- The user explicitly selected version 4.5.0. The release notes must explain changed legacy token/projection semantics despite that version choice. - -## Final coordinator gates - -Local coordinator gates passed: all ten builds/typechecks, 2,383 full-suite tests with Redis/MongoDB/PostgreSQL and all installed optional fixtures (one unchanged downloaded Transformers-model fixture skipped), three Node24 sandbox/OTel conformance tests, four release-lock/CJS declaration tests, both packed-consumer suites, and publint/attw for all ten packages. Docs generation, build, links, 307 complete examples, imports, adapters, recipes, harness/queue smoke, and downloadable archives passed. The documented four-charge example returns exactly 0.072. See the DX review for commands and scope. Remote CI, release commit/tag, npm publication, and live docs verification remain publication gates. - -## Complete implementation source inventory - -This inventory includes both delegated source streams. Coordinator-owned package manifests, release metadata, CLI packed-consumer regression, packaging scripts, and external docs are recorded separately by the coordinator. The executor also updated `.github/workflows/ci.yml` with the PostgreSQL integration service/environment. - -```text -packages/browser/src/browser-agent.ts -packages/core/README.md

Neither behavior should be silently treated as complete permanent accounting. -- `CostTracker.track()` and `getSummary()` are public synchronous APIs. Durable APIs must have explicit asynchronous names and lifecycle rules. -- Parent run summaries are views of leaf charges. Handoffs already avoid charging merged delegated usage twice; preserve that behavior. -- `EventBus.emit()` deliberately isolates listener failures. Store writes and budget decisions must be direct calls with explicit failure handling; events report the result. -- Reranking paths in `rerank/providers/{cohere,jina,voyage}.ts` return ranked documents but discard other response metadata. Add a common measurement sink without changing their ordinary return values. - -## External implementation lessons - -Sources checked on 2026-10-08.

Agentium should expose unknown pricing when required context is absent. | -| [Mastra pricing model](https://github.com/mastra-ai/mastra/blob/main/observability/mastra/src/metrics/pricing-model.ts) and [budget control](https://mastra.ai/reference/processors/token-cost-control) | Separate pricing data from enforcement; explicit scope and warning/block policies. | Its documented budget checks use asynchronously persisted metrics and are approximate. Agentium's stricter admission option requires an atomic accounting store. | - -## Provider evidence that shapes the contract - -- [OpenAI prompt caching](https://developers.openai.com/api/docs/guides/prompt-caching): cache-write input has its own category; it must not also receive ordinary-input billing. -- [OpenAI Fast mode](https://developers.openai.com/api/docs/guides/fast-mode): keep requested and actual tiers; select the billed tier from the returned evidence. -- [OpenAI reasoning](https://developers.openai.com/api/docs/guides/reasoning): Pro mode uses reported aggregated model work; do not invent another token multiplier. Separate Pro model IDs can have separate rates. -- [Anthropic prompt caching](https://platform.claude.com/docs/en/build-with-claude/prompt-caching): ordinary input, reads, and writes are separate; cache creation can contain TTL buckets. -- [Google usage metadata](https://ai.google.dev/api/generate-content#UsageMetadata): preserve reported counts and their provider-specific detail. The installed SDK and current public description differ on the total's explicit tool-use term; retain the original evidence and test the supported version rather than inventing one generic total formula. - -The plan should recheck official rates and contracts when implemented. This review deliberately does not turn today's price table into permanent assumptions. - -## What remains unverified - -No new end-to-end execution was performed. Earlier conversational examples are useful regression scenarios, not fresh test results from this review. Live invoicing, private discounts, SDK-hidden retries, every hosted tool, and all subscription plans need separate evidence. Unknown usage and unsupported prices must be visible in the product until that evidence exists. diff --git a/plans/dx-cost-accounting-review.md b/plans/dx-cost-accounting-review.md deleted file mode 100644 index 66336aa..0000000 --- a/plans/dx-cost-accounting-review.md +++ /dev/null @@ -1,38 +0,0 @@ -# Cost accounting DX audit - -Date: 2026-10-08. Release target: 4.5.0, as requested by the user. - -Scope: Fix; cost-related Agent, Team, Workflow, stream results, configuration, public accounting types, errors, lifecycle, and package entry points. Rules: `api-`, `types-`, `err-`, `config-`, and reached `onboard-` rules. CLI and unrelated package features are outside this audit. - -## Findings and changes - -1. **CRITICAL — `api-sensible-defaults`: common calls required manual coordination.** The first cost example created a tracker, wrapped a function, flushed writes, queried a session, and repeated cleanup. Agent accounting now has one constructor setting, `cost: true`, and a run-level `costs` snapshot. The same contract applies to terminal stream chunks and to Team and Workflow results. Shared trackers remain an advanced option. Accounting stays opt-in. -2. **CRITICAL — `api-predictable-return-shape`: an accounting read failure could lose a successful answer.** Run snapshots distinguish `available` from `unavailable`. Missing prices and missing reads keep `total: null`; a failed read does not invent a known subtotal or repeat the model call. Disabled tracking leaves the optional snapshot absent. -3. **CRITICAL — `api-no-hidden-side-effects`: ownership and nested scope needed explicit rules.** Parent tracking cannot be bypassed by a child setting. A run snapshot includes only that run's descendants, not its siblings. Agent-owned trackers drain at close. Supplied trackers and stores remain caller-owned. Semantic cache hits must not repeat a prior charge. -4. **CRITICAL — `err-stable-error-codes`, `err-suggest-the-fix`: error text was insufficient for recovery.** Accounting conflicts and persistence failures now expose stable codes and tell callers to retry accounting writes, not successful provider work. Public compatibility and budget errors also have stable codes. Configuration conflicts fail at construction. -5. **MEDIUM — `config-optional-with-defaults`: valid tariffs were inaccessible without manual context construction.** `billingContext` supplies trusted account facts once. Provider-returned facts win. It cannot forge provider, model, time, or request identity and does not choose an execution tier. Simple USD thresholds use the existing `maxCostPerRun` shorthand; shared reservations still require explicit scope, period, and bounds. - -Public result/configuration hover documentation and the first-run examples are reviewed under **HIGH — `types-public-jsdoc`** and **HIGH — `onboard-zero-config-quickstart`**. The docs lead with normal calls, then introduce storage, custom tariffs, groups, and reconciliation. - -## Compatibility decision - -The user explicitly selected 4.5.0. Existing method names and signatures remain available. Canonical token semantics correct previous double counts. Legacy synchronous history methods reject canonical records rather than returning an incomplete zero; the migration guide states this observable change. This is a documented compatibility limit, not a claim that all old cost consumers need no migration. - -## Package import finding - -**HIGH — `onboard-exports-resolve-typed`: CommonJS consumers received ESM declarations.** All ten packages now emit a separate `.d.cts` graph, with conditional type exports. The conversion changes local module references only; it preserves external imports and string literal types. Packed consumers and `publint --strict` / `attw --profile node16` pass for all ten packages. The profile covers modern Node ESM/CommonJS and bundler resolution; it does not claim legacy Node10 module resolution support. - -## Verification - -- `npm run build`: all ten packages passed. -- `tsc --noEmit` for each of the ten package configurations: passed. -- `npx biome ci .`: 672 files passed without warnings. -- Full `npm test` with Redis, MongoDB, PostgreSQL, packed consumers, sandbox SDKs, OpenTelemetry, and native LiveKit enabled: 2,383 passed across 226 files.

Native LiveKit audio capture/clear also passed locally without a room connection. -- Docs: 307 complete examples type-checked; 693 static imports, 26 adapters / 29 exports, 810 core/transport/queue exports, and 117 harness exports verified. -- Docs build, page links, seven executed recipes, four harness fixtures, queue smoke, and seven reproducible archives passed. -- The documented synthetic four-charge example executed and returned `0.072` with distinct ordinary input, cache read, cache write, and output charges. - -Release CI, npm publication, and deployed docs are separate final gates.

However `streamOpenAIStyle` currently allows Responses fallback after iteration begins but before a normalized chunk appears. A metadata-only stream can therefore be replayed.

Agent steps produce `${step.name}_output` only when the child completes (an omitted status on a legacy structural child counts as completed). Failed or stopped child output stays in `StepResult.output`, with its text, status and reason. It does not overwrite a successful named output field. + +Conditions accumulate the selected serial branch's patches. Parallel branches start from shallow snapshots, settle all started work, then join only their produced patches in declaration order. The default `merge: "declaration_order"` lets the last declared writer win a collision, including intentional writes of the original value. `merge: "error"` throws `WorkflowMergeConflict` with code `workflow_merge_conflict`, the group name and at most 100 conflicting keys. A strict failed join applies none of that join's patches to its parent, writes no checkpoint and starts no downstream steps. Nested structural failures propagate after started siblings settle; completed external effects remain applied. + +Nested objects are still shared across shallow branch snapshots. Replace nested values in returned patches and keep branch-owned objects separate. Direct mutation of a shared nested reference can affect siblings and the caller's input. This is not a deep isolation mode. + +`failurePolicy: "continue"` collects ordinary errors and runs later serial steps. `failurePolicy: "stop"` records later serial steps as skipped. Already-started parallel siblings settle and successful patches may join. Any error result makes the aggregate `WorkflowResult.status` `failed`, with reason `workflow_step_failed`; skipped conditions alone leave it `completed`. A cancelled child throws `WorkflowCancellationError` with code `workflow_cancelled`. Parent signal cancellation preserves its abort reason. Cancellation escapes collection and retries, prevents late patches/checkpoints/completion, and does not undo remote effects. Standalone configured retries use abortable backoff; controlled effects are never automatically retried by Workflow after a rejected acknowledgement. + +`runWithCheckpoints()` accepts the same caller identity, signal, execution services, mode, metadata and child-supported key/dependency options as `run()`, plus `initialState`. Checkpoints occur after complete top-level steps; conditions and parallel groups each form one boundary. A failed checkpoint save rejects before the next step, even though the completed effect may have applied. + +For validated continuation, configure `definitionVersion` and `validateCheckpointState` together. The validator receives unknown external state and returns the expected state type. These workflows emit format version 2 checkpoints with the workflow name, definition version, ordered top-level step names and absolute cursor. `continueFromCheckpoint(id, opts)` validates all of those before effects, validates restored state, then clones it. Incompatibility or noncloneable state rejects with code `checkpoint_incompatible`. Hosts must bump the version when callable code or captured dependencies change; step names cannot detect those changes. + +Continuation gets a fresh run context by default. Explicit caller options are authoritative; signals, services, credentials and dependencies are never serialized in checkpoint state. New checkpoints retain cumulative results, absolute step indices, `parentCheckpointId` and `parentRunId`. Continuing a continuation skips every previously completed top-level step. State and results are cloned on save, so subsequent ordinary mutation cannot rewrite earlier snapshots. Hosts using JSON stores must validate JSON-compatible state. Keep clients, callable dependencies and secrets in caller options rather than checkpoint state. + +`replay()` and `fork()` are deprecated terminology/compatibility APIs: they execute remaining steps afresh and can repeat later effects. They retain legacy envelope acceptance through the current major, while validating the workflow name and repairing newly written absolute cursors. Version 2 records always receive strict validation, including through the wrappers. Legacy records cannot establish original code identity; callable or opaque legacy state remains accepted where the host store supports it. Ordinary containers are copied, while noncloneable opaque dependencies retain their existing reference compatibility. Do not treat old restarted indices as proof of the original cursor. + +Migrate legacy records offline only after verifying the original workflow, absolute step index, definition version and state. Write the corrected absolute cursor, validated state, format version 2, definition version and ordered step names. The strict continuation API never guesses identity or offers a blanket legacy bypass. The test suite includes an explicit host migration fixture. + +Checkpoints are state boundaries, not recorded model/tool playback, mid-step recovery, approval restoration, inherited active reservations, exactly-once effects or active harness recovery. Safe effect recovery needs an operation intent/receipt ledger, reconciliation, compatible code/backends and adapter atomicity. The Workflow harness adapter remains non-durable. diff --git a/packages/core/src/workflow/__tests__/continuation.test.ts b/packages/core/src/workflow/__tests__/continuation.test.ts new file mode 100644 index 0000000..9c7cfb8 --- /dev/null +++ b/packages/core/src/workflow/__tests__/continuation.test.ts @@ -0,0 +1,334 @@ +import { describe, expect, it, vi } from "vitest";

The testing adapter itself does not depend on eval or a test framework. It fixes the host identity, validates supported `RunOpts`, uses isolated per-run observers and keeps cancelled/failed traces explicitly partial. A structural `Agent` remains a valid `EvalTarget`. + +Keep evaluation sessions separate from live sessions, including any persistent project/repository scope. The adapter accepts `sessionId`, `signal`, `runMode` and matching tenant/user IDs; it rejects options that try to replace host authority or model configuration. It closes owned run resources and its completed evaluation session resources, while borrowed Agents and backing clients stay with the host. + +The runtime records archive references, incremental task summaries and current recall separately. Summaries cover an exact contiguous prefix of complete canonical groups. An unavailable group blocks that cursor; later relevant evidence can still be recalled without advancing the summary past the gap. Summary work requires an available model-call slot while protecting one task call; its task-token floor is advisory and final provider admission still applies. + +Source reads/discovery occur within one bounded cycle before a potentially slow summary model call. Fresh validation windows check the current view after summary work and again before model submission. Terminal publication opens a fresh authorized session and drops invalid derived summaries while retaining canonical records. These checks do not make revocation atomic with provider submission or cross-store publication; hosts needing that guarantee must implement conditional publication/reconciliation. + +Recall budgets bound queries, candidates, response/source bytes, excerpts, estimated evidence tokens, latency and validation. The adapter must stop backend work on abort. Evidence is included whole. Retrieval-stage policy can stop, request bounded clarification or explicitly continue with uncertainty. Insufficient prompt allocation also changes recall to partial; at that stage the policy must stop or explicitly continue. A clarification request after allocation returns `recall_assembly_omitted` because more input cannot repair an unchanged prompt ceiling. `currentSessionRecallPolicy` stops failed/partial evidence and allows an empty accessible result; a host requiring evidence for every answer should reject `no_accessible_evidence` too. The helper's query is the latest user text; production ranking and query formulation remain host choices. + +Recall scope contains tenant, actor and session, plus optional project/repository IDs supplied through `runtime.run(..., { recallScope: { projectId, repositoryId } })`. Enabling continuity on a meaningful legacy snapshot without `memoryScope` requires `attestLegacyMemoryScope: true` from the host. This attests an already verified scope; it is not a bypass for a mismatched scope. A store used for task summaries must advertise `canonicalArchiveReads: true` as well as bounded discovery, reads and current revision validation. + +The [indexed fixture](https://github.com/agentiumOS/agentium/blob/main/packages/harness/src/runtime/__tests__/fixtures/continuity-fixture.ts) demonstrates direct complete-group reads, bounded discovery, revision validation, physical-byte measurements and source deletion. It is a test adapter, not a persistent backend. The [runtime tests](https://github.com/agentiumOS/agentium/blob/main/packages/harness/src/runtime/__tests__/continuity-runtime.test.ts) demonstrate summary reuse, unavailable coverage, cancellation, scope attestation and precommit revocation. + +The verifier reads current host evidence such as artifact digests and test records. `pass` permits acceptance; `fail` stops by default or requests a configured revision; `unknown` stops. Candidate prose and successful tool settlement do not establish verification. Evidence references are bounded to at most 32 entries and 8192 serialized bytes. Revisions share the run budget, and effects remain disabled during revision unless the host explicitly enables them. + +The text scorer above is a minimal wiring example. The [memory acceptance runner](https://github.com/agentiumOS/agentium/blob/main/packages/harness/src/__tests__/context-memory-acceptance.test.ts) separately measures discovered/read evidence, prompt inclusion, answer behavior, stale facts, abstention and scope. It compares full history, incremental summaries and summaries plus recall with equal model/resource settings. Failed graders keep generated output and report infrastructure failures and valid-grade denominators; missing grades are not successes. Offline fake providers establish contracts, not production quality gains. + +## Responsibility and outcome reference + +| Concern | SDK behavior | Host responsibility | +| --- | --- | --- | +| Agent lifecycle | Reject busy close; drain owned memory/accounting; distinguish borrowed resources | Cancel/await admitted work; retry incomplete close; close shared clients | +| Canonical history | Harness session store owns controlled history; ordinary Agent owns its session/memory path | Select storage, retention and coordination; avoid duplicate extraction | +| Context and memory | Label archives, summaries and recall as source data; preserve evidence and uncertainty | Confirm persistent facts; own corrections, validity, deletion and access control | +| Storage identity | Explicit tuple-v1 codecs; legacy defaults preserve old records | Authenticate scope; migrate keys; choose TTLs and backups | +| Budgets | Aggregate logical model calls, tools and token reservations; separate finishing allowance | Select limits; account for physical retries and unknown provider usage | +| Completion | Validate bounded decisions; keep stopped/cancelled/failed distinct; optional current-evidence verifier | Define task proof and revision policy; reconcile uncertain effects | +| Workflows | Join produced patches; enforce strict conflicts/cancellation; validate versioned continuation | Version callable code; validate state; make external effects recoverable | +| Recovery | Snapshots/checkpoints describe completed boundaries; default stores/events are process-local | Durable stores, intent/receipt reconciliation and distributed ownership | + +Ordinary token/model-call limits and reserved finishing allowances are separate.

Inspect `HarnessResult.status`, `reason`, `partial`, `providerFinishReason`, `completion`, `budget` and cleanup diagnostics before presenting success.

It must equal `true` when taskSummary is enabled, alongside residentHistory and the four bounded recall capabilities. A generic query-only reader remains compatible with the original four capabilities. The proposed protocol otherwise had no attestation capable of supporting its required constructor-time rejection of non-seekable canonical archives. Parent agreed; eval fixture advertises it. +2. `HarnessStartOptions.attestLegacyMemoryScope?: boolean` is the explicit host attestation for a meaningful untagged snapshot. `recallScope` accepts only trusted projectId/repositoryId dimensions; it cannot override tenant/user/session. Scope rejection releases the lease without committing or altering the snapshot. +3. All archive and query source I/O occurs under the single unchanged retrieval-cycle deadline **before** awaiting summary generation. Post-summary, pre-submit, and pre-commit checks use fresh finite validation windows. Moving query discovery after arbitrary summary latency would necessarily expire the one source deadline and violate the required long-model-latency fixture; this change does not renew source deadlines or add a hidden retry. +4. Retrieval-stage await_input uses the existing live requestInput mechanism, retains the admitted task slot, appends the reply as canonical user evidence, and consumes remaining source/query/token allowance. Allocation-stage stop or await_input produces explicit `recall_assembly_omitted`; only explicit uncertainty-aware continue submits after omitted source evidence. Allocation requires more prompt capacity or explicit partial continuation, not another hidden retrieval loop. Both decisions use the same strict bounded Zod schema. +5. Current-session policy stops on partial/failed recall. A host may explicitly continue after failure with safe source-status data and no derived evidence. Healthy zero accessible matches remain distinct from backend failure. +6. The runtime's automatic recipe reserves requested output, estimated tool schemas, and a 128-token wrapper margin. The supplied public recipe requires explicit maxRequestTokens/reservedRequestTokens. Final provider-specific request estimation still includes actual projected messages, tools, and requested output. Summary preflight uses a conservative source-byte input allowance plus 1024 tokens for wrapper/control overhead, its output cap, and an explicit essential task floor; final ordinary ledger admission remains authoritative. + +## Integration APIs + +Parent owns public barrels, policies re-export, and README. New public plan types reside in recall.ts/task-summary.ts; the three factories and their option types reside in continuity-policies.ts.

The parent reports the corrected handoff fixture first produced two intended missing-metadata failures and then passed after implementation; this supersedes its earlier construction-only failures. The source correction is independently visible and the final tests pass. + +Disposition of prior findings: + +- **Reflection: closed.** Revised output adopts all selected terminal metadata and public messages, clears obsolete structured output, and does not invoke a further critic after a stopped revision. +- **Handoff metadata: closed.** Nonstream manager returns reason/partial/provider finish metadata, and source streaming adoption copies it from the target result. +- **Cache incomplete-result false success: closed.** Cache reads/writes apply `isReusableCacheResult`, including status, partial and provider finish checks; historical incomplete records are ignored. Pre-aborted and delayed awaited paths now check cancellation. One remaining first-publication edge appears below. +- **Empty tool batch false success: closed.** Generate and stream reject with a typed `invalid_model_response` error carrying partial evidence. The direct exported loop's usage carrier has a separate counting defect below; Agent's wrapper masks it, so the Agent-only regression passes. + +Remaining actionable issues found during correction verification: + +### P2 — Observe every settled member of a cancelled tool batch + +`packages/core/src/agent/llm-loop.ts:609–611` and `:981–983` invoke `observeTool` inside the per-result processing loop. The harness observer records settlement, then its post-effect `ensureActive` rejects on cancellation. That exits the loop after its first result; remaining already-settled results are journaled in `finally` but never sent to the settlement observer. + +Confirmed using public `createHarnessEvalTarget` + `agentDriver` with two parallel tools and a barrier ensuring both apply before abort. Observed `{ "applied": 2, "calls": 1, "status": "cancelled", "observed": ["one"], "coverage": "partial" }`. Conservative partial coverage is correct but does not justify discarding a known second settlement. The parent explicitly requested this adjacent M6 integration check; this is not a review of unfinished recall/eval behavior elsewhere. + +Correction: give all already-settled results an observation-only phase before cancellation/control middleware can terminate processing, or otherwise guarantee settlement-only observation of every remaining result. Do not invoke post-tool enforcement/transform hooks or new model/tool work after abort, and do not observe the first result twice. Add a two-result cancellation regression for run and stream. + +### P2 — Direct loop protocol-error usage is doubled + +`packages/core/src/agent/llm-loop.ts:942` passes `observedUsage(chunkUsage)` to the new empty-batch error after `chunkUsage` was already added to accumulated totals at `:904–911`. A direct exported `LLMLoop.stream` probe reporting usage `2/1/3` carries `4/2/6` in `error.output.usage`. Agent.stream reconstructs the error with its separate usage accumulator, hiding this from the new Agent-level test. + +Correction: use the already accumulated `observedUsage()` at that point and assert direct-loop error evidence as well as the public Agent wrapper. + +### P2 — Cache-hit event cancellation still permits the first text chunk + +`packages/core/src/agent/agent.ts:1264–1270` emits `cache.hit` and immediately yields cached text without rechecking its signal. An ordinary EventBus observer can abort the caller controller on receipt of that event. Confirmed public Agent/real cache probe: the first iterator result is `{ type: "text", text: "cached" }` while `signal.aborted` is already true. The subsequent guard prevents the finish but does not prevent this first publication. + +Correction: check the signal after `cache.hit` emission and immediately before yielding cached text. The run cache path already checks after its awaited usage lookup. A small public streaming regression pins the missing boundary. + +All three correction-verification issues were sent to the parent immediately. They are concrete local failures, not speculative requirements. Parent edits continue, so final closure requires checking their eventual corrected state; no additional source files were edited by this reviewer. + +## Final core correction disposition, 2026-10-13 01:22 UTC + +All prior core findings are now **closed in the reviewed source state**. The direct streaming loop's invalid-response carrier uses the accumulated `observedUsage()` exactly once. The cached stream checks its signal immediately after the `cache.hit` event and before yielding text. Both loop modes invoke the optional evidence-only `observeToolSettlements` once for the settled batch before per-result cancellation/control processing. Harness uses a run-local WeakSet to keep ordinary/delegated observations from duplicating those batch observations; observer failures are bounded diagnostics and cancellation still prevents new work. + +Fresh reviewer regression command selected core cache-outcomes, protocol-terminals, reflection-outcomes, native streaming-handoff, harness eval-target, and context-memory-acceptance: **6 files / 84 tests passed**, 06:52:54 local time. This includes the direct-loop counting/event-boundary regressions and the actual two-applied-effect cancellation fixture. The streaming batch source branch was independently inspected; at this moment the two-effect adapter fixture pins the ordinary Agent path. Any later streaming extension will be recorded in the expanded review. + +No remaining actionable core correctness or specification defect was found in this pass. M5/M6 continuity/measurement findings and their correction evidence are tracked separately in `continuity-eval-review.md`. Source remains concurrently edited; this is scoped review evidence, not a final package or release gate. + +Final expanded reviewer selection at 06:58:14 local time: **16 files / 222 tests passed**.

Existing `agent` config properties, ordinary Agent compatibility, wrappers and conversation runners remain supported. The existing object-keyed weak-map session reservation continues until the actual underlying target callback settles, including ignored cancellation. +- Legacy valid score results normalize to `graded`. Valid zero/false is a task failure. Invalid/thrown scorer results and malformed model judge payloads become `infrastructure_error`; case grading is incomplete, overall pass stays false, and timeout/cancellation classifications remain intact. +- `CaseLifecycle` captures the generated output at actual target settlement, before its post-operation deadline check. Judge timeout/cancellation preserves that output and never restarts generation. +- Legacy totals/average remain available. New complete-grade denominator, infrastructure-case count, and valid-grade mean separate execution coverage from grading coverage. An empty valid-grade denominator reports null. +- `createHarnessEvalTarget` exists only in the existing optional testing subpath. No core/harness eval import or dependency was added. Target capture preserves class ability/policy receivers, fixed verified identity, declarative grants/budgets, explicit-session history, and per-run observer isolation. +- Only sessionId/signal/runMode and identical userId/tenantId are accepted RunOpts. Specified unsupported options fail before provider work. Failed native status maps to error; legacy awaiting_input maps to stopped. Original status/reason/budget and cleanup diagnostics are weak-map observations on the returned output object. TTFT stays absent. +- Tool traces contain bounded IDs/names/errors/denials with source bodies omitted. Count/byte overflow, observation errors, failed/cancelled status conservatively mark partial coverage. A partial prefix cannot establish forbidden-effect absence. Runtime-owned session resources close after settlement; borrowed pools and existing Agent instances remain host-owned. + +The parent/continuity runtime owners supplied the cancellation-safe settlement hook. Regression evidence exposed a core guard preceding settlement observation, then a second whole-batch problem: both concurrent effects applied but only one settlement reached the observer after cancellation.

The adapter now records both effects once while preserving cancelled/partial status and one model invocation. + +## M6c fixture and interpretation + +`context-memory-eval.v1.json` pins corpus revision (now context-memory-v1.1), source ID/revision/location, valid alternative evidence groups and model-visible sufficiency clauses, fake task/summary model snapshots, scorer version, generation settings, common execution/context bounds, and twelve scenarios. Labels are outside agent-visible input and source data. The recorded task provider receives an object without the gold fields. + +The acceptance runner uses real HarnessRuntime, Agent driver, context projection, bounded host RecallStore, canonical archiving, incrementalTaskSummaryPolicy, session storage, aggregate admission, and completion verification. It has no live network dependencies. The twelve scenarios cover correction/supersession; archived early requirement; two source sessions; retrieved-but-omitted prompt evidence; stale answer with correct gold context; uncertainty; environment conflict; tenant/project collision-shaped IDs; deadline/cancellation/partial retrieval; malicious source instructions; incomplete trace; and successful execution settlement with exitCode1 rejected by completion. + +Metrics are measured at distinct boundaries: + +- Discovery hit@5 uses returned candidate references. Any sufficient evidence hit differs from all-required-group coverage; equivalent current sources satisfy the same group. +- Read coverage uses complete query evidence from actual RecallResult, excluding incomplete spans and separate canonical-summary reads. +- Assembled coverage inspects actual model request references. Canonical archive references resolve through captured, host-validated message records only to identify the labelled source locations. Content credit requires the actual prompt wrapper text to retain every pinned sufficiency clause for that source. Summary reference retention, summary content coverage, and full-source prompt coverage are separate fields; absent archive bodies are never rehydrated as model-visible evidence. Complete retained historical source messages are measured independently. No retrieval metric searches a final answer for citations. +- Final correctness, source support, stale use, conflict answer, appropriate insufficient-evidence abstention, and unnecessary answerable-case abstention are separate deterministic checks. Merely having references does not make a stale npm answer supported. +- Logical calls, prompt/completion/total tokens, unknown usage, source/discovery bytes, measured backend retrieval duration, total continuity duration, total task duration, and prompt evidence tokens are retained separately. Canonical preparation read bytes/time and actual summary provider calls/tokens/time are explicit. Cold and amortized preparation cost are equal in these one-task cold fixtures; no warm-cache saving is claimed. + +A paired two-session task runs full history, incremental summary with query recall disabled, and incremental summary plus bounded query recall from identical host-scoped source data/task sequence. It holds task snapshot, generation settings, grants, budgets and context ceiling constant. Observed cold model counts are 1/2/2 and summary preparation calls 0/1/1; all retain both evidence groups in the prompt and produce the correct deterministic output. Full history exceeding the common context ceiling fails before task provider dispatch and is recorded as an infeasible baseline. + +These fixtures verify exact runtime/measurement contracts, not stochastic model quality, prompt-injection resistance of a real model, or statistical equivalence. The versioned pilot envelope is proposed only: 24 scenarios × 3 conditions × 3 repeats, 216 task runs, concurrency2, declared task/judge limits, severe invariant blocking, one bounded follow-up then inconclusive for noisy quality shifts. It is marked not authorized/not run. Actual evaluation spend: zero provider calls billed; all provider responses are local recorded fixtures. No pricing or live quality claim is made. + +## Red evidence and scope + +- Initial eval target/integrity selection: 49 passed / 3 failed. Missing grade coverage, lost completed output after judge timeout, and malformed JSON judge incorrectly classified were the three intended red failures. +- Initial adapter selection: 19 failures, all from the missing createHarnessEvalTarget API. Once implemented, remaining semantic failures were corrected test fixture assumptions (denial is the existing string union; policy method is decide), and the cancellation settlement regression remained red until core/runtime integration. +- Parallel-effect regression: both effects applied and one model call ran, but observed tools contained only first_effect. It passed after the shared batch port/dedup correction. +- M6c added red checks for absent archival-summary preparation and summary-only correctness; these passed after actual summary preparation/three-condition execution. Source-support red caught a stale answer being treated as supported solely due to references. Partial-span red caught incomplete query evidence counted as sufficient. Any-hit red caught conflating a single valid required-group hit with complete multi-group coverage. +- Existing behavior/extra adapter edge checks that passed on first execution are characterization coverage, not claimed red evidence.

Reproduction used the actual summary-only condition with a valid-ID draft containing only “Unrelated update retained.” Both new tests failed with assembled coverage1 even though the deployment requirement was absent from the actual task prompt. This was a measurement defect; runtime summary validation correctly established only reference/range integrity. + +The correction parses actual prompt wrapper text and checks versioned gold sufficiency clauses plus exact ID/revision/locator. The scorer version is now `source-group-and-visible-content-v2`. Retained-reference coverage, summary-reference coverage, summary-content coverage, full-source prompt coverage, and combined assembled coverage are distinct. Summary reference IDs never recover text absent from the prompt. A third regression retains only the superseded npm statement with valid current evidence IDs: reference coverage1, summary/full-source/assembled content coverage0, stale-use1, unsupported/incorrect answer. + +The summary-only paired condition now explicitly omits full archived excerpt bodies, preserving only summary/status projection; the earlier condition included canonical archive additions alongside the summary and therefore was not a sufficiently isolated summary-only comparison. Current paired evidence establishes summary-content coverage1 and full-source prompt coverage0 for that condition. The prompt-allocation source fixture was reduced to 80 repeated context sentences and revised to r2/corpus v1.1 so complete canonical preparation + complete query reading fit the fixed 2048 evidence-token ceiling while the full source still exceeds the 400-token prompt allocation. This preserves the intended retrieved-but-not-assembled contract without widening budgets. + +The two-parallel-applied-effect adapter regression is now parameterized over actual Agent.run and Agent.stream through agentDriver. Each path applies two effects, invokes the provider once, observes both IDs once, and returns cancelled/partial. The ordinary path's prior red evidence is retained; the streaming extension passed initially on the already-fixed shared implementation and is integration coverage, not a manufactured red claim. + +Post-correction check at 06:56 UTC: adapter + memory acceptance **55 tests passed** (31 adapter,24 acceptance), harness full source/test TypeScript check passed.

No provider/network or source changes were used. + +Requirement: E3 explicitly requires a signal check before publishing the next accepted chunk/event.

The two direct-loop regressions exercise suspension at the last public delta and last completed event, including failure observation and preservation of already settled usage. Repeated the original public source probe independently: after abort, the remaining event was only `message.failed`, followed by `RunCancelledError`; no raw text leaked. +- **Published guides: closed.** Core's allowlist now includes the two exact storage/workflow README paths; harness includes `DEPENDABILITY.md`. Same-package links stay local, while optional sibling-package and repository-only fixture links use explicit repository URLs. Reviewed installed-package guide assertions and the worker's completed `final-package-green.log` (**2 passed / 1 deliberately filtered skip**) plus `final-pack-dryrun.log` (both core guides and harness guide included). Hosted target checks prove paths against the local source tree; they do not assert that unmerged new files already exist on remote main. Final freshly rebuilt package behavior remains the parent's gate. +- **Cancellation prose: closed.** The guide now distinguishes admitted `Agent.run` cancelled output from early/pre-admission and streaming rejection. +- **Existing cost lifecycle fixtures: accepted.** Their earlier close-waits expectations contradicted the approved M3 busy-close behavior. The updated tests assert `AGENT_BUSY` without closing the owned tracker, allow provider/hook work to finish, verify totals `0.072` and `0.144`, then close exactly once. No production-close rollback or weakening occurred. + +Fresh reviewer command: `npx --no-install vitest run packages/core/src/agent/__tests__/publication-cancellation.test.ts packages/core/src/cost/__tests__/agent-cost-dx.test.ts packages/core/src/agent/__tests__/agent-close.test.ts --reporter=dot` — **exit 0, 3 files / 28 tests passed**, local start 07:06:25.

Conditions/serial execution accumulate produced writes. Default parallel ordering is declaration order, independent of settlement timing; intentional writes of an unchanged value remain owned writes. Strict conflict detection happens before parent mutation, and structural conflict/cancellation rethrows through every parent only after started parallel siblings settle. A failed strict join cannot produce a checkpoint or downstream call. Earlier checkpoints/external effects remain evidence. + +Ordinary failures are collected by default, but never produce aggregate completed. Stop policy skips later serial entries, including unstarted groups; already-started parallel siblings settle and successful patches may join. Error/stopped child text/status/reason stays in StepResult.output with no named state patch. A legacy child with missing status remains completed. Cancelled children throw WorkflowCancellationError; parent signal preserves its existing abort reason. Checks after function/Agent awaits, joins, checkpoint waits and final accounting prevent known cancellation becoming completion. Backoff uses the existing abortable helper with timer cleanup. Controlled dispatchEffect rejections are never automatically retried by Workflow. + +Construction requires definitionVersion/validator together. v2 records bind workflow name/version/ordered top-level names/absolute index and step name; Zod validates the external envelope, then the host validator recovers state. Strict restored state is structured-cloned before dispatch/fork mutations. Saved state/results are cloned; continuation starts from prior results and writes absolute indices with parent checkpoint/run lineage. Caller identity/mode/signal/metadata/services/policy apply to the fresh context; supported child apiKey/dependencies/questions are forwarded but not checkpointed. No blanket legacy bypass exists in strict continuation. + +Compatibility ruling: do not require a strict definition version/validator or matching historical step name for unversioned replay/fork. Those wrappers validate workflow name and bounded cursor, keep legacy acceptance through this major, and write corrected absolute indices going forward. Historical restarted cursors cannot prove original identity; explicit offline migration must establish the original absolute index/version/state. v2 records are strict even through legacy wrappers. Generic legacy checkpoints may contain callables/opaque clients in custom non-JSON stores; ordinary containers are recursively copied, retaining references only for noncloneable opaque dependencies. Applying structuredClone rejection to every legacy wrapper/save would introduce the prohibited patch-level compatibility break. Strict v2 rejects noncloneable restored state. JSON-backed stores still require host JSON-compatible state validation. + +Shallow branch snapshots are a documented compatibility limitation: direct nested mutations can affect siblings/input. A negative fixture deliberately proves it. No deep isolation, recorded playback, mid-step recovery, exactly-once effects, restored approvals/reservations or durable harness execution is claimed. + +## Red/green evidence + +All commands ran from `/Users/xerycks/.codex/worktrees/core-harness-dependability/agentium` on 2026-10-13 with existing dependencies/Vitest 4.1.11. + +1.

Safe effect recovery needs an operation intent/receipt ledger, reconciliation, compatible code/backends and adapter atomicity. The Workflow harness adapter remains non-durable. + +## Dependency graphs and bounded replanning + +`GraphStep` adds a dependency episode to the existing Workflow. Each node has an `id` and an ordinary Agent, function, condition, parallel, graph or repeat step. `dependsOn` declares control order; `inputsFrom` declares both readiness and data flow. Control predecessors may be done or skipped. Data producers must be done. A failed or blocked predecessor blocks its consumers; a skipped condition releases a control join but cannot supply data. Blocked nodes appear as skipped with reason `workflow_dependency_blocked`, and make the graph fail. + +```ts +import { Workflow, type GraphStep } from "@agentium/core"; + +type BuildState = { left: number; right: number; total: number }; +const graph: GraphStep = { + name: "calculate", + maxConcurrency: 2, + graph: [ + { id: "left", step: { name: "readLeft", run: async () => ({ left: 2 }) } }, + { id: "right", step: { name: "readRight", run: async () => ({ right: 3 }) } }, + { + id: "sum", + inputsFrom: ["left", "right"], + step: { name: "sum", run: async (state) => ({ total: state.left + state.right }) }, + }, + ], +}; +const calculation = new Workflow({ + name: "calculation", register: false, + initialState: { left: 0, right: 0, total: 0 }, steps: [graph], +}); +const result = await calculation.run(); // total = 5 +``` + +Ready nodes start incrementally, up to `maxConcurrency` (positive safe integer, default 5). This is a node limit, not an aggregate tool/provider concurrency ceiling: an Agent or nested parallel step can start its own work. Hosts must encode resource ordering or supply locks where effects share a file, browser, database object or account. Missing data dependencies do not establish safe external-effect concurrency. + +Every complete graph is checked before that episode's effects: unique IDs, valid step shapes, references, duplicate edges, cycles in the union of both edge types, limits and `maxNodes` (default 100). Static nested definitions are checked too. Dynamic factories are checked at entry; scoped graph/repeat composition has depth limit 64. Per-episode and repeat bounds multiply under nesting; there is no separate total expansion budget. Harness budgets still control aggregate expenditure. + +Graph nodes receive separate structured clones of entry state plus patches from their transitive data ancestors. Control-only predecessors and unrelated completed siblings do not contribute data. State and returned patches must be structured-cloneable. This isolates ordinary nested data between nodes; it cannot isolate resources captured by trusted callbacks. Replace state with owned patches as for other Workflow steps. + +Inputs, result order and final joins use stable topological order, breaking ties by declaration order. Completion timing does not choose patch winners. The new graph defaults to `merge: "error"`, which rejects overlapping owned keys from incomparable nodes in the dependency union, including same-value writes. A descendant can intentionally overwrite its predecessor. `merge: "declaration_order"` opts into later writers in that stable topological order. Existing ParallelStep keeps its original declaration-order default. Successful independent nodes can contribute patches when another node fails; failed or skipped nodes contribute none. A conflict/cancellation rejects the boundary, prevents downstream Workflow steps and its checkpoint, and does not undo effects already issued. + +A `graph` factory can select a new complete episode from current state. Combine it with `RepeatStep` to repair after observations: + +```ts +import { Workflow } from "@agentium/core"; + +const repair = new Workflow({ + name: "bounded-repair", register: false, + initialState: { attempts: 0, verified: false }, + steps: [{ + name: "repair", maxIterations: 2, + while: (state) => !state.verified, + repeat: [{ + name: "episode", + graph: (state) => [{ + id: state.attempts === 0 ? "first-try" : "repair-try", + step: { + name: "check", + run: async (input) => ({ attempts: input.attempts + 1, verified: input.attempts === 1 }), + }, + }], + }], + }], +}); +``` + +The repeat predicate is pre-tested with the zero-based number of completed iterations. It is checked after the last allowed body too: false succeeds, still true returns `workflow_iteration_limit` through Workflow/harness/eval. Body errors stop repetition. Each graph factory runs once at episode entry, after previous work has settled. Replanning does not modify running nodes, reuse stale outputs automatically or stream unvalidated plans. Hosts may map validated model proposals into an approved executable catalog; node-produced text is data and never automatically gains host-instruction authority. + +Scoped graph node IDs and repeat iteration paths appear in `StepResult.executionPath`, workflow events, Agent child session IDs and `metadata.workflowExecutionPath`. Segments use `encodeURIComponent`. Function effect names become `workflow:`, such as `workflow:calculate/left/readLeft`; grant those explicitly under harness control. Legacy function names outside these scopes stay `workflow:`. Agent output keys stay `${step.name}_output`, so distinct nodes writing the same key require ordering or an explicit merge choice. Paths are diagnostic identity, not remote idempotency keys or durable attempt receipts. + +Existing Agent bounds, signals and ExecutionServices are reused. Graph/repeat does not reset shared harness model/tool/token budgets or add a retry owner. Agent limits apply to each new Agent invocation; the shared harness budget caps the complete run. Ready work is chosen incrementally, so timing can change which node wins the remaining shared budget. Cancellation stops admissions, propagates to node execution, waits for started work to settle and discards late patches. Uncooperative host callbacks can delay cancellation. Deliberate repeat can issue effects again; controlled Workflow never automatically retries a rejected effect acknowledgement. + +Graph and repeat are complete top-level checkpoint boundaries. A saved completed boundary is skipped on validated continuation; internal nodes or iterations are not separately checkpointed. A crash, cancellation or failed save can cause an unsaved boundary's effects to run again from an earlier checkpoint. Definition versions must cover factory/callback/environment changes. Recorded replay, mid-graph resume and external-effect reconciliation require a separate host adapter. The existing durable ledger/supervisor are not automatically connected, and the harness driver keeps `durable: false`. diff --git a/packages/core/src/workflow/__tests__/execution-graphs.test.ts b/packages/core/src/workflow/__tests__/execution-graphs.test.ts new file mode 100644 index 0000000..f51af45 --- /dev/null +++ b/packages/core/src/workflow/__tests__/execution-graphs.test.ts @@ -0,0 +1,336 @@ +import { describe, expect, it, vi } from "vitest"; +import type { Agent } from "../../agent/agent.js"; +import type { RunOpts } from "../../agent/types.js"; +import { EventBus } from "../../events/event-bus.js"; +import { InMemoryStorage } from "../../storage/in-memory.js"; +import { StorageBackedCheckpointStore } from "../checkpoints.js"; +import type { GraphStep, RepeatStep, StepDef } from "../types.js"; +import { Workflow } from "../workflow.js"; + +type State = Record & { count: number; checked: boolean; output?: string }; +const initialState: State = { count: 0, checked: false }; +const workflow = (steps: StepDef[]) => + new Workflow({ name: "execution-graphs", register: false, initialState, steps }); + +describe("execution graph Workflow integration", () => { + it("exits a repeat without effects when its first guard is false", async () => { + const effect = vi.fn(async () => ({ count: 1 })); + const result = await workflow([ + { + name: "already-verified", + repeat: [{ name: "effect", run: effect }], + while: () => false, + maxIterations: 1, + }, + ]).run(); + expect(result.status).toBe("completed"); + expect(result.state).toEqual(initialState); + expect(effect).not.toHaveBeenCalled(); + }); + + it("rejects recursively generated graph composition before any leaf effect", async () => { + const recursive: GraphStep = { + name: "recursive", + graph: () => [{ id: "again", step: recursive }], + }; + await expect(workflow([recursive]).run()).rejects.toMatchObject({ code: "workflow_definition_invalid" }); + }); + + it("joins dependency data before downstream work and preserves ordered overwrites", async () => { + const observed: State[] = []; + const graph: GraphStep = { + name: "pipeline", + graph: [ + { id: "build", step: { name: "build", run: async () => ({ count: 1 }) } }, + { id: "unrelated", step: { name: "noise", run: async () => ({ output: "unrelated" }) } }, + { + id: "check", + inputsFrom: ["build"], + step: { + name: "check", + run: async (state) => { + observed.push(state); + return { count: state.count + 1, checked: true }; + }, + }, + }, + ], + }; + const result = await workflow([graph]).run(); + expect(result.status).toBe("completed"); + expect(result.state).toEqual({ count: 2, checked: true, output: "unrelated" }); + expect(observed).toEqual([{ count: 1, checked: false }]); + expect(result.stepResults.map((row) => row.stepName)).toEqual(["pipeline", "build", "noise", "check"]); + expect(result.stepResults.find((row) => row.stepName === "check")?.executionPath).toBe("pipeline/check/check"); + }); + + it("replans at each bounded episode and succeeds when the predicate becomes false at the cap", async () => { + const plans: number[] = []; + const guards: number[] = []; + const repeat: RepeatStep = { + name: "repair", + maxIterations: 2, + while: (state, iteration) => { + guards.push(iteration); + return !state.checked; + }, + repeat: [ + { + name: "episode", + graph: (state) => { + plans.push(state.count); + return [ + { + id: state.count === 0 ?

See [research](research.md) for pinned primary sources. + +Agentium already supplies serial, condition and parallel `Workflow` steps, owned patches, Agent loops, ToolExecutor, controlled ExecutionServices, shared harness budgets, boundary checkpoints and evaluation adapters. `core/src/graph` is a knowledge graph, not an execution scheduler. Choose an explicit workflow DAG containing existing bounded Agent/function/structural steps, with a bounded repeat step for adaptive episodes. A second Agent tool-plan scheduler is deferred: existing ToolExecutor already parallelizes a model's complete tool batch, and a second planner/retry/budget owner is not needed here. + +## Additive contract + +- `GraphStep`: `name`, `graph: WorkflowGraphNode[] | ((state: T) => WorkflowGraphNode[])`, `maxConcurrency?: number` (default 5), `maxNodes?: number` (default 100), `merge?: 'error' | 'declaration_order'` (default error). +- `WorkflowGraphNode`: unique nonempty `id`, existing `step: StepDef`, optional `dependsOn: string[]` and `inputsFrom: string[]`. +- `dependsOn` is a control edge: a predecessor must finish done or skipped. `inputsFrom` is a data edge and also a scheduling edge: its producer must finish done. Failed/blocked predecessors block consumers. A skipped condition can release a control join but cannot satisfy a data input. +- Node input is a structured clone of graph entry state plus patches from transitive data ancestors only, in stable topological order. Other completed siblings never leak into that input. Returned patches are cloned at settlement. Graph state and patches must be cloneable; trusted callbacks still retain any references they capture outside the SDK. +- Scheduling uses the union of control and data edges. Validate the complete episode before effects: IDs, references, duplicate edges, cycles, positive safe integer limits and node count. Stable topological order breaks ties by declaration order. Ready nodes start incrementally within maxConcurrency. Lifecycle: pending → running → done/error/skipped; blocked nodes are skipped with a reason. Inputs, results and joins are deterministic for fixed patches; timing, admissions against a shared budget and external effects are not. +- Final join uses stable topological order. Strict merge rejects keys written by incomparable nodes in the dependency union; ordered rewrites are allowed. Declaration-order mode means stable topological order with declaration ties. Conflicts abort the boundary, do not checkpoint it, and do not undo effects. Failed nodes contribute no patch; successful independent nodes can contribute even when another node fails. +- `RepeatStep`: `name`, `repeat: StepDef[]`, `while: (state: T, iteration: number) => boolean`, required positive safe integer `maxIterations`. Pre-test predicate uses zero-based count of completed iterations. At most that many bodies run. If still true at the bound, return an error with `workflow_iteration_limit`; stop on body error. A graph factory inside repeat reads previous observations and selects the next fully validated episode. No in-flight graph replacement or streamed partial plans. +- Add optional `executionPath` and `reason` to StepResult, and optional `executionPath` to workflow.step events. Graph IDs/iteration paths distinguish repeated step names, effect names and Agent child sessions. This is local causality, not an idempotency key or a durable per-attempt receipt. + +## Ownership and reliability + +The host supplies executable nodes and any mapping from a validated model proposal to an allowed step catalog. Raw model-produced IDs/functions are never executed. Node/tool/retrieved outputs remain data and Agent inputs; they do not become host instructions. The graph scheduler owns readiness and state joins; StepRunner owns execution; Agent owns its local reasoning/tool loop; ExecutionServices/host owns policy, shared budgets, approvals and controlled effect retry. Standalone existing retryPolicy remains available; controlled effects are never retried by Workflow. Intentional repeat is new work and can repeat external effects. + +Signal cancellation stops admission, propagates through existing node execution, drains started work, then discards late patches. Cancellation is cooperative; an uncooperative callback can delay settlement. maxNodes/concurrency/repeat limits bound structural work, existing Agent limits bound local work, and harness budgets bound shared model/tool expenditure. Parallel nodes must be safe for the host's resources: absent dependencies do not prove external-effect independence. + +Existing versioned checkpoints cover completed top-level graph/repeat boundaries. Successful saved boundaries are skipped on continuation. No mid-graph/iteration resume, remote atomicity, exactly-once effects or recorded playback is promised. A crash/save failure can repeat a whole unsaved boundary. Existing DurableTaskSupervisor/ActionLedger/RunRecords are candidates for a later host adapter; harness durable capability stays false. Hosts must bump definitionVersion for changed factories, dependencies or callable code. + +SDK owns contracts, validation, scheduling, patches, bounds and tests. Hosts own storage, resource locks, policy, credentials, retention, model choice, idempotency and reconciliation. No graph database/library dependency is needed. + +## Integration finding + +Real harness fixtures exposed a pre-existing policy identity bug: root `dispatch`/`dispatchEffect` passed both the context's lazy policy wrapper and its underlying policy to ToolExecutor, so one operation could consume two tool admissions. The integration reuses the same context policy identity for these root executors. Separate local/host policy composition in ToolExecutor is preserved. Four direct regressions cover exact-one-admission execution and host denial; graph function effects can now use an exact requested tool budget. `workflow_iteration_limit` also propagates as an additive aggregate reason through the existing driver/evaluation adapter. diff --git a/plans/execution-graphs/harness-fixtures-report.md b/plans/execution-graphs/harness-fixtures-report.md new file mode 100644 index 0000000..889054b --- /dev/null +++ b/plans/execution-graphs/harness-fixtures-report.md @@ -0,0 +1,90 @@ +# Execution graph harness fixtures + +Date: 2026-10-13.

The focused test's failing admission assertion is therefore the intended missing graph behavior, not a provider/network/setup failure. All fixture providers are offline and task keyed. + +## Fixture method and coverage + +The ten source integration cases exercise real Workflow, workflowDriver, HarnessRuntime, ordinary Agent and ToolExecutor execution. Only provider responses and safe primitive fixture records are substituted. Each provider response is selected by the current task and tool phase, never a shared response index. Gates are explicitly released in cleanup. Agent instances are closed. Literal expected states/call counts are independently derived. + +Covered contracts: + +- Incremental readiness in A/B → C(A), D(A/B) → E(C/D), with maxConcurrency 2 and safe read tools. C starts while B is held; D starts while C is held; E waits for both. Data-only edges and transitive ancestor inputs are checked. All five tasks execute once. +- Concurrent global model admission admits at most two of three ready Agents and blocks a consumer requiring all three. Accepted independent states account for timing-dependent budget admission; the fixture does not promise a deterministic winner. +- Repeat graph episodes retain the same global model and tool ledgers, release reservations, and scope Agent sessions/metadata by iteration. Tool denial is measured from actual settlements; the deterministic provider may still answer after denial, so this test makes no false assertion that every denied tool forces an Agent failure. +- Cancellation after a controlled fixture effect applies drains the held callback, discards its late patch, admits no consumer, and yields exactly one cancelled terminal result. +- A controlled function applies then rejects acknowledgement under configured retryPolicy. It applies once, its consumer is blocked, and evaluation retains failed/partial observation and the error settlement. This fixture records the rejection; it does not claim a durable unknown-outcome receipt or safe replay. +- Node/user/tool instruction text stays in data messages. System host fragments, verified identity, plan mode, and scoped child metadata remain authoritative. Grant-shaped predecessor data cannot authorize an ungranted dependent function effect. +- Distinct encoded node IDs scope duplicate Agent step names and child history while the legacy `_output` key remains intact; the ordered overwrite is dependency comparable. +- The unchanged createHarnessEvalTarget reports failed repeat exhaustion with `workflow_iteration_limit`, exactly two effects, truthful structured/text state and partial observation. Direct Agent.run and the existing Agent driver/evaluation caller remain working. + +The primitive tools are isolated deterministic reads or writes to test-owned counters/keys with explicit prerequisites. Graph independence does not make arbitrary writes to shared host resources safe. These tests establish only the covered SDK contracts, not durability, exactly-once external effects, mid-episode recovery, live LLM quality, production latency, or release readiness. + +## Offline comparison + +`scripts/compare-execution-graphs.ts` is a reproducible structural comparison using the existing public Agent/Workflow harness adapters and evaluation target. Three paired cases cover chain, fan out, and the shared prerequisite DAG. Both conditions receive the same task manifest and run the same provider implementation, primitive tool, host grants, budgets (`16` model calls, `16` tool admissions, `128` tokens, zero revisions), output/roundtrip caps and isolated state. The old Agent loop may request all currently ready independent tools in one batch; the graph uses maxConcurrency 2. + +Output includes exact normalized/raw outputs, statuses/reasons, task/effect/model request ledgers, duplicate/dependency errors, model/tool admissions, declared tokens, unknown usage, reservations, observation coverage, primitive overlap, local wall time and costs. Failed/infrastructure rows retain their denominator. Unknown production billing is null; offline provider charge is zero. There is one deterministic run per case/condition, no judge, and no stochastic variance claim. Local wall time has no simulated provider delay and measures fixture overhead only; it is not a speedup estimate. The gated integration case establishes incremental readiness separately. + +## Integrated verification + +The coordinator notified this contributor after core and harness builds completed with exit zero. The contributor then ran only the scoped fixture: + +```text +npx vitest run packages/harness/src/__tests__/execution-graphs.test.ts +exit 1; 9 passed, 1 failed (10 tests), 294ms test duration. +``` + +Log: `harness-fixtures-green.log` in this report directory. The only failure is one controlled deterministic function effect being charged twice: callback applications = 1, actual observed tool settlements = 1, budget.toolCalls.used = 2 instead of 1. This is a preexisting harness policy accounting issue exposed by the new graph fixture. `HarnessRuntime` gives the root context a wrapper executionPolicy that delegates to the budget-owning policy, while `dispatchEffect` also gives that policy to ToolExecutor. ToolExecutor intentionally evaluates distinct context/local policies, so the same `admitTool()` executes twice. The fixture assertion has not been weakened. + +A minimal legacy single-function Workflow probe with `maxToolCalls: 1` confirms the functional consequence: applications = 0, status = failed, used = 1, structured = {}. The single permitted effect is denied by the second evaluation. Evidence was sent to the coordinator, who owns production integration changes. + +The coordinator independently reproduced this on both direct dispatch and function-effect dispatch, then corrected the harness executors to reuse the same lazy context policy identity. Core composition of distinct local policies was preserved. The contributor reran the original fixture after this source correction: + +```text +npx vitest run packages/harness/src/__tests__/execution-graphs.test.ts +exit 0; 10 passed (10 tests). +``` + +Final log: `harness-fixtures-final-green.log`. This proves the ten covered integration contracts against the coordinator-built core and the corrected harness source. The initial failing integration log is retained. This is a targeted source fixture pass, not a full suite/build/packed-consumer claim. The source state is a dirty `agent/execution-graphs` integration based on `f5e4434723c33f2610416bee789c78bb32787315`, with frozen types, graph-runner, StepRunner/repeat, aggregate limit reason and harness executor policy correction; HEAD alone does not describe the tested state.

Scope: ReAct, OpenHands, and LLMCompiler only. This note contains no Agentium code inventory and makes no claim about guarantees already implemented in Agentium. Paper evidence appears first; subsequent recommendations are engineering judgment for the architecture owner. + +The recommended direction is a hybrid: an explicit workflow controls state transitions and contains bounded Agent executions; an Agent may optionally schedule a validated dependency graph of tools. The two graph levels solve different problems. The workflow determines when a stage is complete, what state it may change, and which stage follows. The tool graph determines which already-authorized operations can run together and which results must precede another operation. + +## What the papers establish + +**ReAct — adaptive behavior inside an agent.** Section 2 describes an agent choosing actions from accumulated observations and actions, augmented by language thoughts. Thoughts update context without changing the environment. Plans can change after observations; the pattern is a sequential decision process rather than a declared dependency scheduler. Section 3.3 also documents repetitive reasoning/action failures and failures after uninformative search. This supports retaining local adaptation without assuming that prompting supplies a reliable termination contract. [ReAct v3, §2](https://arxiv.org/html/2210.03629v3#S2), [§3.3](https://arxiv.org/html/2210.03629v3#S3.SS3). + +Reported performance: the paper reports absolute success-rate improvements of 34 and 10 percentage points over its imitation/reinforcement learning comparators on ALFWorld and WebShop.

[ReAct v3, §4](https://arxiv.org/html/2210.03629v3#S4). + +**OpenHands — separate decisions, history, and execution.** Sections 2.1–2.2 define an agent step consuming state and returning an action, a chronological event stream of actions/observations/user interactions, and a runtime that executes actions and returns observations. State also carries cost and delegation metadata. Section 2.4 represents delegation as an action to another agent. These are useful separation boundaries; they do not themselves define a workflow scheduler. Appendix E uses stored prompt/response matches to make integration tests deterministic. That testing technique should not be mistaken for deterministic production replay or a durable effect protocol.

Tools may themselves be specialized LLM agents. Section 3.4 allows results to trigger a new task graph; §4.2 streams ready tasks before planning finishes. Thus each planning episode can be a DAG while the overall execution contains a replanning cycle.

Start with workflow nodes that call the existing Agent execution abstraction and return typed results. Add tool dependency scheduling where the workload benefits from it. There is no research requirement that every tool call become a persistent workflow node, or that every task begin with a model-generated graph. + +## Proposed boundaries for Agentium + +These are design recommendations requiring integration with the actual runtime; they are not observed Agentium behavior. + +**A workflow node owns a state transition.** It receives an immutable logical snapshot, produces owned updates and evidence references, and ends with an explicit outcome such as success, failure, cancellation, budget exhaustion, or an unresolved external effect. Edge predicates use a named snapshot and outcome. Simultaneous branches must have disjoint write ownership, a deterministic reducer/stable order, or a surfaced conflict. Join policy must specify whether it requires all branches and how it treats partial failure; completion timing must not select the winner. + +**An Agent node owns bounded adaptation.** It may reason, call tools, and revise its local plan within inherited deadline, iteration, tool, and cost limits. Exhaustion is an observable terminal outcome, not a model-generated success message. The parent run remains the authority for cancellation and the overall budget. A nested Agent cannot create a fresh unlimited allowance. + +**A tool scheduler owns readiness, not truth.** Missing data-dependency edges are insufficient proof that operations are safe to overlap. Two calls without input/output dependencies may mutate the same file, shell, browser session, account, or external object. Parallel execution should require declared resource/effect compatibility or a conservative allowed set. Validate the full referenced input contract before dispatch. Initially prefer complete validated planning episodes; streamed execution requires an incremental validation and authorization rule before any early effect. + +**Replanning changes future work.** Represent each plan with a revision and retain the causal observations used to produce it. A replan may append or supersede pending tasks. Completed results can be reused only when their inputs and relevant environment assumptions remain valid. Superseded/cancelled attempts must not write into the current revision when they finish late. Already-issued effects remain part of history and may require reconciliation; replacing a graph cannot undo them. + +**Evidence has provenance and limited authority.** Separate model proposals and summaries from runtime observations and external receipts. A graph edge proves intended dependency, not factual correctness. A tool's successful transport response proves only what that tool contract reports; it may not establish the user's requested outcome. A node claiming completion should refer to the relevant observed checks or receipts. Preserve links among run, graph revision, node attempt, request, observation, and downstream decision. Route/completion logic should use validated outcomes rather than treating narrative confidence as a state mutation. + +## Guarantees the research leaves unresolved + +The cited architecture/execution descriptions are not a sufficient specification for any of the following. This is a limit of the evidence, not a claim that a current project lacks the capability. + +| Concern | Agentium decision still required | +| --- | --- | +| Persistence | Whether the run is intentionally in memory or durable; actual storage, commit boundary, retention, serialization, schema/code compatibility, and crash windows | +| Recovery | Whether restart reuses completed observations or reruns work; how ready/running tasks are restored; how recorded state relates to mutable sandbox/external state | +| Retries | A single retry owner per operation, bounded attempts, and distinctions between transient, permanent, and ambiguous outcomes | +| External effects | Stable logical effect identity tied to inputs, separate from attempt identity; destination idempotency, transactions, receipt reconciliation, compensation, or explicit resolution | +| Cancellation | Propagation to child work, handling of late results, and fencing of stale attempts; cancellation does not prove a remote effect was undone | +| Replay | Recorded model/tool/clock/random outcomes versus new sampling; history inspection, recovery, and deliberate re-execution must have different effect policies | +| Concurrency | Resource access, rate limits, deterministic state merges, duplicate completion handling, branch failures, and scheduling fairness | + +In particular, a crash after a remote mutation but before recording its result creates an unknown outcome. A checkpoint or event stream alone cannot make the mutation atomic with local state. Reconcile that uncertainty before an unsafe retry; an outbox alone does not establish once-only remote execution. + +Performance expectations for Agentium remain unmeasured. Any speedup depends on the critical path, tool latency, allowed concurrency, planning overhead, model calls, and effect serialization. Evaluate representative work at matched correctness and budget limits before adopting the paper's performance figures as targets. + +Useful acceptance scenarios for the integration owner are: a downstream task cannot run before all inputs exist; branch completion order does not change merged output; an invalid dependency fails before dispatch; replanning fences late old results; budget exhaustion terminates nested work; cancellation blocks new downstream dispatch; and a simulated effect/result crash preserves uncertainty without blindly duplicating the effect. Replay checks should supply recorded outcomes and establish that inspection/recovery does not unexpectedly execute tools. diff --git a/plans/execution-graphs/runtime-inventory.md b/plans/execution-graphs/runtime-inventory.md new file mode 100644 index 0000000..bd3ff61 --- /dev/null +++ b/plans/execution-graphs/runtime-inventory.md @@ -0,0 +1,146 @@ +# Execution graphs: runtime inventory and reuse design + +Inspected on 2026-10-13 in `/Users/xerycks/.codex/worktrees/core-harness-dependability/agentium`, branch `agent/execution-graphs`, HEAD/base `f5e4434723c33f2610416bee789c78bb32787315`. Source references describe this base; later concurrent parent implementation edits are outside the inventory. Source investigation was read-only. No implementation, commits, builds, installs, model calls, external effects or test execution were performed.

Reuse StepRunner's owned-patch result internally, the existing Agent and function leaf execution, RunContext, and neutral ExecutionServices. Keep graph scheduling separate from the Agent's model/tool loop. Keep Workflow's current top-level checkpoint boundary and accurately describe continuation as fresh remaining work. + +This supports dependency scheduling and rebuilding a graph at a bounded loop boundary without changing Workflow into a second lifecycle owner or claiming per-node durable recovery. There is already a durable task/action subsystem in this base; use it for a later explicit recovery adapter instead of inventing another generic intent/receipt ledger. That subsystem is currently disconnected from Workflow, Agent's ExecutionServices and the local harness driver lifecycle. + +## Existing facilities + +| Facility | Observed contract and evidence | Reuse consequence | +|---|---|---| +| Step topology | `StepDef` is an Agent/function/condition/parallel union. Conditions contain a serial child list; parallel contains child steps. No execution edges, loop variant, dependency IDs or topology compiler appear in these types. `packages/core/src/workflow/types.ts:7`, `:20`, `:26`. | Additive variants can preserve the established class/step API. A knowledge graph store is unnecessary. | +| Serial execution | StepRunner copies state shallowly, executes declared steps in sequence, accumulates produced patches and results, and stops/skips later serial work when configured. `packages/core/src/workflow/step-runner.ts:39`, `:49`, `:55`, `:59`. | Serial nesting and patch accounting are usable unchanged. | +| Branching | A condition evaluates once against the current state. False means skipped; true executes its nested serial list and returns the accumulated child patch. There is no else/exclusive-route primitive. `packages/core/src/workflow/step-runner.ts:169`. | Existing conditions can be graph nodes. Route semantics should be expressed through declared skip gates or a new graph built at a boundary, rather than inferred from failure. | +| Parallel join | Started branches receive shallow snapshots; all settle before join. Produced owned patches are merged in declaration order, independent of settlement order. `merge: "error"` surfaces colliding keys. `packages/core/src/workflow/step-runner.ts:185`, `:191`, `:202`, `:219`. | Reuse the internal patch outcome and merge rule. Do not reconstruct a patch by comparing returned state to its input. | +| Ownership/isolation | Function output must be an owned non-null, non-array object; dangerous prototype keys are discarded. Nested objects remain shared across shallow snapshots. `packages/core/src/workflow/step-runner.ts:101`, `:159`; `packages/core/src/workflow/README.md:7`. | Graph ancestry can scope the supplied logical input. It is not deep isolation or a sandbox for trusted closures. | +| Agent node execution | `inputFrom` projects state to text; otherwise all state is JSON encoded. Child options forward identity, signal, mode, services, policy and supported caller dependencies. Completed text becomes `${step.name}_output`; error/stopped output is evidence only; cancelled child output throws structural cancellation. `packages/core/src/workflow/step-runner.ts:113`, `:119`, `:120`, `:134`, `:150`. | Agent nodes can keep this behavior. Node identity must be distinct from the existing step-name label and from each Agent attempt identity. | +| Ordinary failure | Step exceptions become error results; cancellation and strict merge conflicts escape collection. Parallel ordinary failures still allow successful sibling patches to join. Any error result makes Workflow failed. `packages/core/src/workflow/step-runner.ts:89`, `:195`, `:220`; `packages/core/src/workflow/workflow.ts:180`. | A graph must define blocked descendants and terminal aggregate behavior explicitly. Failure must not masquerade as a successful dependency. | +| Workflow retries | Standalone leaf exceptions can retry with exponential abortable backoff. Structural errors never retry. Supplying ExecutionServices disables Workflow retry after rejected acknowledgement. Returned error/stopped Agent outcomes are error results, not thrown retry triggers. `packages/core/src/workflow/step-runner.ts:228`, `:237`, `:134`. | Preserve retry ownership. Adding graph repair must not wrap the existing controlled effect in a blind retry. | +| Workflow lifecycle | Workflow owns its event bus, context, optional cost scope and result aggregation. Its `run` executes the configured steps; standalone cancellation throws and emits run.error. `packages/core/src/workflow/workflow.ts:83`, `:163`, `:192`, `:227`. | A GraphStep should remain inside this lifecycle. Avoid an unrequested new registry or lifecycle layer. | +| Checkpoints | Save after each completed top-level step; a condition or parallel group is one boundary. State/results are cloned. Save rejection stops before the next step. `packages/core/src/workflow/workflow.ts:259`, `:283`, `:303`; `packages/core/src/workflow/checkpoints.ts:8`. | GraphStep and RepeatStep would each be a single boundary initially. No successful-child recovery is implied. | +| Validated continuation | Version 2 records bind workflow name, definition version, ordered top-level names, absolute cursor and validated cloneable state. Continue executes from the following top-level index under a fresh caller context. `packages/core/src/workflow/workflow.ts:317`, `:330`, `:361`, `:396`. | Reuse strict envelope checks. Hosts still bump definitionVersion for changed code/closures; names do not detect it. | +| Deprecated replay/fork | These wrappers execute later effects afresh; they are not recorded playback. `packages/core/src/workflow/workflow.ts:370`, `:381`; `packages/core/src/workflow/README.md:17`, `:21`. | Graph history inspection and graph execution must have separate names and guarantees. | +| Neutral execution port | Core consumes host-owned model/stream, owned-work tracking, tool observation, dispatch, arbitrary effect dispatch and conversation-record operations. Core does not own the host's orchestration or resource lifecycle. `packages/core/src/agent/execution-services.ts:17`, `:20`, `:42`, `:54`, `:60`. | A graph scheduler can use this boundary without importing harness into core. | +| Controlled Agent loop | Each Agent run gets a local executor/loop. Model calls are proxied to supplied services. Duplicate Agent/service tool owners fail. Controlled Agent reflection, handoff and model-backed compression fail closed because the host must own them. `packages/core/src/agent/agent.ts:161`, `:174`, `:479`, `:498`, `:518`, `:540`. | Host graph nodes can call Agent; repair and replan policy belong outside the controlled Agent loop. | +| Tool execution | Tool batches require unique call IDs, execute in bounded chunks, settle started work and retain caller-order results. Arguments validate before effect execution; host/local policy and approvals remain mandatory. No general tool retry or structured effect-state result is provided. `packages/core/src/tools/tool-executor.ts:174`, `:179`, `:249`, `:278`, `:357`; `packages/core/src/tools/types.ts:66`. | Reuse authorization and execution. A tool result's error string cannot safely classify a write as absent or retryable. | +| Loop/transcript bounds | maxToolRoundtrips counts tool batches; the controlled loop retains its counter across invocations, and the last permitted batch can be followed by final model output. Native Agent reflection is rejected under supplied services. Canonical exchanges are recorded separately from request projections; settled tool evidence is observed before cancellation-sensitive processing. `packages/core/src/agent/llm-loop.ts:196`, `:336`, `:396`, `:421`, `:609`, `:618`, `:649`; `packages/core/src/agent/agent.ts:167`. | A graph repair count is an additional decision bound. It does not replace model/tool budgets or make fresh sampling replay. | +| Agent checkpoints | CheckpointManager stores roundtrip/messages/usage/session state; LLMLoop writes it after tool exchanges. There is no Agent checkpoint-resume entrypoint in this base. `packages/core/src/checkpoint/checkpoint-manager.ts:8`, `:25`, `:48`; `packages/core/src/agent/llm-loop.ts:684`. | These are retained state records, not a graph node task-result ledger. | +| Harness drivers | ExecutionDriver is an open structural interface; Agent/Workflow/Team adapters all advertise durable:false. Workflow driver calls `workflow.run`, not checkpoint continuation. `packages/harness/src/runtime/driver.ts:170`; `packages/harness/src/drivers.ts:19`, `:111`, `:127`. | An existing Workflow adapter can execute added GraphSteps. A standalone custom graph driver is possible without registry schema redesign. | +| Harness recovery claims | Constructor rejects durable:true and replace control without a recovery/checkpoint adapter. `packages/harness/src/runtime/driver.ts:308`. | Graph support does not justify changing durable capability flags. | +| Shared admission/control | Harness budgets reserve logical model calls/tokens synchronously and count tool admission; tools cannot widen grants. Controlled model preparation combines host/node signals and deadlines. `packages/harness/src/runtime/budget.ts:16`, `:81`, `:114`, `:119`; `packages/harness/src/runtime/driver.ts:796`, `:878`, `:921`. | Reuse the root budget instead of creating independent budgets per graph node. Hard token claims remain estimator-dependent. | +| Owned work/resources | Harness tracks promises, stops accepting new work, closes streams and waits for owned work before releasing resources/session writer. Agent close rejects while busy; owned resources drain separately. `packages/harness/src/runtime/driver.ts:627`, `:1525`, `:1724`, `:1780`; `packages/harness/src/runtime/session-bindings.ts:77`, `:87`; `packages/core/src/agent/agent.ts:566`. | Await graph-started children and maintain ownership through cancellation. Existing waits are cooperative and may be delayed indefinitely by noncooperative work. | +| Completion revision | Harness has validated accept/revise/stop/await_input decisions. Revise re-enters the whole driver, is bounded by maxRevisions, and denies effect admission by default on revision. `packages/harness/src/runtime/controller.ts:20`, `:42`; `packages/harness/src/runtime/driver.ts:804`, `:1651`, `:1675`, `:1703`. | Whole-driver revision is not node repair. A Workflow driver also expects JSON state-patch input; arbitrary revision text is not automatically a valid workflow request. | +| Portable binding | Harness registry resolves approved driver/controller/policy IDs and versions without executing them. `packages/harness/src/runtime/runtime-registry.ts:6`, `:34`. | Generated plans should name approved bindings; never turn model strings into imports or arbitrary executable callbacks. | +| Knowledge graph | GraphStore provides entities, edges, traversal/search; GraphRAG translates retrieval queries to Cypher and returns rows. `packages/core/src/graph/types.ts:1`, `:42`; `packages/core/src/graph/retriever.ts:42`, `:55`. | These have no scheduling/attempt/effect semantics and should retain their existing meaning. | + +## Durable facilities already in the pinned base + +`DurableTaskStore` supports atomic updates to one bounded task aggregate, compare-and-set, fencing, task identity and immutable admitted definition fields. An update callback is synchronous and may be reevaluated; it cannot perform effects. `packages/core/src/durable/types.ts:32`, `:83`, `:102`, `:105`; `packages/core/src/durable/store.ts:131`. The default task aggregate limit is documented as 2 MB. Independent tasks have independent budgets; shared graph accounting would need one root budget or a coordinating reservation mechanism. `packages/core/src/durable/README.md:39`, `:43`. + +`DurableTaskSupervisor` leases/fences work, polls cancellation, limits task attempts, records monotonic token/cost reservations and waits for its action ledger to quiesce. Recovery changes executing actions to unknown. Unknown actions prevent ordinary handler entry and require a separate fenced reconciliation path. Terminal tasks cannot be revived. `packages/core/src/durable/supervisor.ts:51`, `:63`, `:124`, `:156`, `:169`, `:183`, `:202`; `packages/core/src/durable/store.ts:155`. Its reserve method is explicit host accounting, not an automatic bridge from HarnessBudgetLedger. + +`DurableActionLedger` already supplies the effect identity contract missing from generic dispatch: stable host-chosen action ID, canonical prepared hash over destination/arguments/connector/policy/grants/identity, stable derived idempotency key, atomic dispatch intent, confirmed result references, unknown outcomes and connector reconciliation. A reused ID with different prepared inputs fails; confirmed actions return their existing result reference. A dispatched exception remains unknown. `packages/core/src/durable/actions.ts:14`, `:21`, `:54`, `:69`, `:80`, `:114`, `:147`, `:173`, `:190`. Destination enforcement or authoritative receipt reconciliation still determines actual effect safety; a checkpoint cannot supply it. + +`DurableRunRecords` persists bounded events and digest-checked JSON snapshots/artifact references. JournaledDurableTaskStore journals task-state transitions in the same task CAS. Snapshot bytes and references have separate persistence steps and do not transact with a remote effect; graph snapshot schema/version validation remains the adapter's job. `packages/core/src/durable/records.ts:12`, `:78`, `:194`, `:219`, `:230`; `packages/core/src/durable/README.md:67`. + +Source search found no integration of DurableActionLedger, DurableTaskSupervisor or DurableRunRecords in Workflow/Agent ExecutionServices/the local harness driver. Therefore the honest initial contract remains boundary continuation. A future adapter can put graph runtime state in a versioned bounded task extension, use fenced updates for per-node result/plan commits and route supported effects through the existing action ledger. Generic shell/email/payment tools remain unsupported for automatic recovery until they have an explicit connector contract. + +## Options and recommendation + +| Option | Advantage | Concrete limitation | +|---|---|---| +| Lower a static DAG into existing serial parallel groups | Almost no leaf execution changes; natural barrier checkpoints. | Cannot derive owned patches through the public executeSteps result; global accumulated state leaks unrelated outputs; topology and skip gates remain opaque. Dynamic graph construction, blocked dependencies and ancestry still need new code. | +| Add GraphStep and RepeatStep to StepRunner | Smallest first-party extension; preserves Workflow, existing adapter, lifecycle and checkpoint shape; graph nodes can contain existing composite steps. | Needs a compiler/scheduler, scoped node identity and shared internal patch outcome. Recovery stays at the containing top-level boundary. | +| Add a separate core ExecutionGraph class plus harness adapter | Clean graph-specific results and later recovery schema. | Adds lifecycle/registry/public API decisions before they are needed. Existing Servable/registry explicitly knows Agent/Team/Workflow (`packages/core/src/serve.ts:42`, `:70`). | +| Implement a custom harness ExecutionDriver | Already possible through the open driver and approved registry reference. Good for a graph-specific host integration. | Does not add ordinary core Workflow graph support. Durable:true is rejected; neutral dispatch still lacks graph attempt/effect identity. | + +Recommend the additive step design for boundary-only graphs, with a shared internal `StepExecution` contract carrying `state`, `patch` and `results` (`packages/core/src/workflow/step-runner.ts:7`). Do not make private StepRunner details a public API solely for reuse. Keep generated/portable graph definitions as data plus approved host executors; local callbacks stay local. A durable graph runtime is a separate adapter capability, with additional acceptance evidence, rather than an automatic side effect of accepting a graph definition. + +## Contract review of the candidate GraphStep + +The parent candidate is `graph: WorkflowGraphNode[] | ((state) => WorkflowGraphNode[])`, positive finite maxNodes/maxConcurrency, merge default error or explicit declaration_order; nodes contain `id`, `step`, control `dependsOn` and data `inputsFrom`. The following decisions make that candidate concrete. + +### Topology and input ancestry + +1. Validate each materialized graph before any child effect: unique nonempty IDs, known references, no self edges, finite configured bounds and a DAG over the union of control and data edges. Count and validate callback output at runtime; TypeScript does not validate restored/model-generated arrays. Decide whether duplicate edges normalize or reject. Validate nested graph/step structure or impose an expansion-depth bound so cyclic object references cannot recurse indefinitely. +2. Control dependencies gate readiness; done/skipped satisfy the gate and an error blocks it. Data dependencies gate readiness and require done. An inputsFrom edge is also a scheduling dependency, even if absent from dependsOn. +3. Build each node's supplied state from the graph-entry base plus owned patches of its transitive data ancestors only, in stable topological order with declaration index as tie-break. Control-only ancestors contribute no payload. Runtime injection dependencies in RunOpts are credentials/host bindings and have no graph-edge meaning. +4. Define write comparability using the union dependency graph, while defining visible ancestry using only data edges. For final graph state and each node input, writes from ordered ancestors may overwrite in the declared order. Incomparable colliding writes fail in error mode; declaration_order is an explicit alternative. Do not permit settlement order to choose a winner. Same-value writes count as owned writes. +5. No shared incremental global state should be handed to a newly ready node. That would expose unrelated completed branches and make inputs completion-order-dependent. Treat per-node result/patch records as immutable once committed. + +Representative edge table: + +| Edge | Readiness | Payload supplied to target | +|---|---|---| +| research-A inputsFrom join | research-A must be done | A's patch and its data ancestors | +| research-B inputsFrom join | research-B must be done | B's patch and its data ancestors | +| authorization dependsOn publish | authorization done/skipped | No authorization patch through this edge | +| join inputsFrom publish | join must be done | Join's patch and its data ancestors | + +The logical ancestry contract does not imply physical confinement. Existing branch snapshots are shallow; a function can mutate nested input or access captured objects. If graph input isolation is to be enforced, use a graph-specific clone/freeze/data validator and specify compatibility for callable/opaque state. Do not silently change all Workflow state to a JSON-only format. The current documented ownership discipline is the lowest-impact alternative, but it must be presented as a trusted callback contract. + +### Deterministic scheduling, conflicts and results + +Stable sorting of currently ready nodes is insufficient to guarantee stable admission under a work-conserving scheduler: a fast A can admit A's descendant before B's descendant; shared budget exhaustion can then choose a different winner. The smallest deterministic implementation is ready-frontier waves sorted by stable topology/declaration order, with bounded fixed chunks, settlement of already-started nodes and a commit/join barrier before advancing. The cost is waiting for unrelated slow siblings. An incremental scheduler is viable if the declared guarantee is stable inputs/conflicts/results, while outbound admission order remains concurrency-dependent. + +Graph node IDs must be carried in results and attempt metadata. Existing workflow.step events carry only runId/stepName/status (`packages/core/src/events/types.ts:101`); Agent sessions are derived from step.name (`packages/core/src/workflow/step-runner.ts:121`). Unique graph IDs do not prevent duplicate step names from sharing a child session. Scope child sessions by graph location/node ID and ensure nested graphs/repeated iterations are distinguishable. Preserve a logical node identity separately from a fresh execution/attempt ID. + +A blocked node needs a stable recorded reason such as failed_control_dependency, failed_data_dependency or skipped_data_dependency. It may map to the existing skipped StepResult status for compatibility, but it must not appear to have executed. Decide aggregate outcome when a skipped data dependency blocks a required terminal: an upstream false condition alone should not accidentally yield a successful publish outcome. A failed ancestor already produces an aggregate error; pure skip propagation needs an explicit completion rule. + +Strict conflict is a structural failure. Settle all started work before reporting it, apply none of the failed join's patches to its parent, record completed external effects as evidence and admit no downstream work. The graph can preserve per-node records in memory for diagnostics while keeping its parent-state update atomic. Do not describe this as rolling back effects. + +### Cancellation and ownership + +Check cancellation before materializing the graph, before each dispatch, after builder/predicate results, after every child settles and before state/checkpoint commit. Synchronous callbacks cannot be preempted; no late callback/child result may advance the run after abort is known. All already-started children remain owned and must settle before their Agent/resource/session owners are released. The current StepRunner and harness enforce cooperative barriers; neither can promise bounded shutdown for a tool/function ignoring its signal. + +Use the graph node's immutable attempt context for StepRunner events and Agent child metadata. Function dispatch currently uses `dispatchEffect(name,args,execute)` without an optional context, while the harness implementation always runs policy/observation with the root context and a fresh random toolCallId (`packages/core/src/agent/execution-services.ts:60`; `packages/harness/src/runtime/driver.ts:1548`, `:1566`). `dispatch` has the same missing context parameter. Passing node metadata only to step.run does not automatically attribute host tool policy/receipts to the node. If per-node causal attribution is promised, add a backward-compatible context/request identity option or an explicit graph effect adapter; metadata alone is not a stable intent ledger. + +## Bounded repeat, repair and replan + +The candidate RepeatStep is `repeat: StepDef[]`, `while(state,iteration): boolean`, `maxIterations: positive integer`. Specify iteration as zero-based completed-body count. Evaluate before the first body; false performs zero work. After each completed body evaluate the next guard on the resulting state. At maxIterations, a still-true guard returns a stable exhaustion error without another body dispatch; false completes. Specify the resulting repeat patch and child results, and whether ordinary errors under failurePolicy:continue allow another iteration. Strict conflict/cancellation must always escape; failurePolicy:stop must prevent another loop body. + +Repeating a GraphStep builder provides boundary replanning: the callback sees the previous completed iteration's observations and materializes the next bounded DAG. This is a useful limited contract. It does not rewrite the topology of running nodes or restart a failed parallel sibling. Builder invocation count is bounded by the outer repeat, maxNodes counts each graph materialization, and maxConcurrency counts graph node execution slots; it does not cap tools inside concurrent Agent/composite nodes. Document those units. Nested repeats/graphs need either a total expansion bound or an explicit statement that local bounds multiply. Shared host model/tool/token/deadline admission still applies. + +Model-directed repair should be a new bounded decision rather than an invisible transport retry. Use an explicitly bound controlled model role and validate its plan/patch output before child effects. Harness controlModel already provides tool-free, grant-bound shared-budget policy calls (`packages/harness/src/runtime/driver.ts:1248`, `:1261`, `:1278`, `:1301`), but core should consume a host callback or neutral model operation rather than import this harness method. + +For future in-flight replanning, constrain edits to pending nodes at a quiescent commit boundary. Retain completed node definitions/inputs/results and causal ancestry. Reject edits that invalidate running/completed node inputs; otherwise the adapter must fence superseded attempts, cancel their children, retain late-result/effect evidence and explicitly handle downstream invalidation. Attach a plan revision, parent revision, validated change and attempt epoch to each committed transition. A fresh output correction does not erase a confirmed effect. That larger contract is not supplied by invoking a builder every time a GraphStep is entered. + +## Resume and side-effect claims + +Initial GraphStep/RepeatStep support can truthfully retain existing Workflow continuation: a completed top-level graph/repeat is skipped on continuation, later top-level work executes afresh, and nested successful siblings inside an incomplete boundary have no recovery record. Continuing from an earlier saved boundary can execute those siblings again. Boundary checkpoint failure can occur after the effect applied. Preserve the current no-auto-retry-under-services rule and describe this loss window directly. + +A future per-node recovery adapter needs versioned graph topology/materialized plan, stable graph/node/effect identities, input digests, node output/patch references, dependency/route decisions, completed-node records, attempt state/fence, repair/iteration counters and retained root budget/deadline semantics. Validate restored state and approved code/binding versions before any effect. Recorded upstream model/tool outputs must drive resumed downstream decisions; fresh model sampling is new execution. Read-only history inspection should make zero calls. Deliberate fork/reexecution must declare its effect-identity policy. + +The existing DurableTaskStore/actions/records supply storage and intent machinery, but the graph adapter still has to connect them: atomic fenced node-result plus scheduler-state updates; connector-backed effect dispatch; reconciliation before uncertain retry; blob/reference expiry/corruption handling; explicit old-schema rejection or migration. The action ledger's stable ID must be tied to logical effect intent and unchanged inputs, not a new node attempt UUID. A reused action ID with changed arguments must fail, as the existing ledger already does. Arbitrary Agent-issued calls cannot automatically acquire these guarantees merely from a node checkpoint. + +Harness session `replayable` and retained conversations are not such an adapter: its snapshot has history/state/revision and an external-store lease contract, while the local event store is bounded in-process history. `packages/harness/src/runtime/session-bindings.ts:7`, `:19`, `:32`, `:40`; `packages/harness/src/runtime/events.ts:76`. Do not use durable driver capability flags or exact-playback wording until a recovery adapter actually implements the complete contract. + +## Focused checks to propose during implementation + +These checks were not executed for this inventory. + +- Validate malformed/duplicate IDs, missing/self dependencies, dependency-union cycles, callback size overflow and recursive structural definitions before child effects. +- Run A/B in reversed settlement order and verify identical data-only ancestor inputs, ordered same-value writes, strict incomparable conflicts, final state/result order and selected admission-order guarantee. +- Verify done/skipped control gates, done-only data gates, failed/blocked descendants and required terminal behavior.

No skipped tests or unhandled rejection warnings in GREEN. + +Behavioral coverage includes: + +- Inverted branch completion with stable topological patch/result joins and flat callback results. +- Incremental readiness for `A/B; C <- A; D <- A,B; E <- C,D`, explicit concurrency bounds, and default concurrency 5. +- Transitive `inputsFrom` ancestry only; control ancestors and completed siblings do not leak into input. Nested base/input mutation and later retained patch mutation cannot overwrite captured scheduler state. +- Copied, frozen dependency arrays, captured episode options, same-value owned writes, declaration-order joins, strict incomparable writer conflicts before downstream admission, and comparable control-descendant rewrites. +- Skipped condition control release versus skipped data blocking; failed and blocked transitive gates; ordinary callback rejection recorded once without retry; nested child errors discard their node patch while retaining flat evidence. +- Cancellation/definition/merge fatal errors and signal abort stop admissions, drain all started callbacks, and discard late successful patches. +- Factory clone isolation, single materialization, node bounds, propagated factory throws, malformed factory output, deferred nested factories, uncloneable entry state, and fatal uncloneable successful patches with sibling draining. +- Invalid IDs, dependency arrays/duplicates/references, mixed-edge cycles, invalid positive safe integer limits/merge, malformed runtime execution kinds, malformed static nested graphs, recursive definitions and excessive nesting rejected before node effects. A predecessor in both dependency lists remains valid. + +Synthesized blocked results have `workflow_dependency_blocked`, skipped status, duration 0, and a relative encoded `node.id/node.step.name` execution path. Ordinary synthesized callback rejection has `workflow_node_failed` and the same relative path form. The coordinator must prefix those two synthesized result cases; executed callback results already carry their caller-owned scoped paths. + +## Limits and integration responsibility + +Only the focused scheduler test command was run. Full workflow/harness tests, TypeScript checks, builds, packed consumers, broad suites and final Biome formatting remain coordinator-owned. These 45 tests establish scheduler behavior with controlled callbacks; they do not establish full StepRunner/Workflow integration or supported CI platform coverage. + +The scheduler validates static nesting through depth64 and defers nested factory materialization until entry. The coordinator owns the runtime depth cap across dynamically generated nested factories, root GraphStep results, root failure policy, execution paths/events, repeat loops, callback execution/retry ownership and checkpoint boundaries. + +Cancellation is cooperative: an uncooperative started callback delays rejection until it settles. Draining does not undo remote effects. There is no mid-episode durability, graph-level retry, streamed replanning, benchmark claim or recovery/idempotency guarantee. diff --git a/plans/execution-graphs/sdk-eval-inventory.md b/plans/execution-graphs/sdk-eval-inventory.md new file mode 100644 index 0000000..d2c9fef --- /dev/null +++ b/plans/execution-graphs/sdk-eval-inventory.md @@ -0,0 +1,137 @@ +# Execution graph SDK and evaluation inventory + +Date: 2026-10-13. Inspected branch: `agent/execution-graphs`. Inspected source HEAD/base: `f5e4434723c33f2610416bee789c78bb32787315`. Checkout: `/Users/xerycks/.codex/worktrees/core-harness-dependability/agentium`. + +Scope: source inspection and proposed acceptance/evaluation contracts only. No implementation, build, install, test execution, live model call, commit or external effect was performed. The original checkout's ongoing recovery work was not imported or modified. Source references below are relative to this isolated checkout and use inspected one-based lines. + +Applied guidance: API and Interface Design, TypeScript and Agent Evaluations skills from the original checkout's `.agents/skills`. No applicable `AGENTS.md` was found in either checkout or the checked ancestor paths. + +## Recommended scope + +Keep `Workflow` as the orchestration API and retain the ordinary bounded `Agent` loop for node reasoning/tool use and repair. Reuse `workflowDriver` and the neutral `ExecutionServices` port. Existing public contracts already provide typed serial state, conditional steps, parallel groups, failure policies, cancellation, owned patches, strict conflicts and completed-boundary continuation. Those capabilities alone do not justify a second graph class, driver, evaluation execution loop, graph database or graph library. + +The useful differentiating case is an explicit dependency DAG with shared prerequisites and successors that should not wait for unrelated work. For example: start A and B; C depends only on A; D depends on A and B; E depends on C and D. C must start while B is still running, and D must start after B while C is still running. A tree composed from today's nested serial/parallel groups introduces an extra barrier or repeats A. A scheduler that runs complete topological levels also introduces an extra barrier. Demonstrating this case would justify one opt-in graph definition capability; serial examples and ordinary fan-out/join do not establish the need. + +The smallest candidate public surface is a graph group added to `StepDef`, containing named existing steps, dependency references, a finite concurrency cap and the existing merge vocabulary. A group would remain one top-level Workflow checkpoint boundary. This is a proposal for design review, not an implemented type or a settled scheduler contract. It avoids changing the meaning of existing `steps`, constructor callers, state patches, named Agent output fields or checkpoint cursors. A separate `WorkflowConfig` graph mode is possible, but requires more result/cursor/documentation decisions and should not be introduced alongside a graph group without a concrete consumer. + +First-version graph-native cycles are not necessary to evaluate the DAG benefit. Bounded repair can stay inside an existing Agent node or an explicitly bounded host routine. If graph-native repeat is required by the final specification, it needs an explicit finite visit/iteration bound shared with aggregate budgets and a documented terminal reason; a dependency cycle must never silently become an executable unbounded loop. Reject unsupported cycles before effects. Do not reset Agent bounds or harness budgets on each repair attempt. + +## Public contract inventory + +| Source | Existing capability | Consequence for graph work | +| --- | --- | --- | +| `packages/core/src/workflow/types.ts:7-30` | `StepDef` is Agent, Function, Condition or Parallel; callbacks return `Partial`; conditions select nested serial work; parallel has `declaration_order`/`error` merge. | Reuse node execution contracts; an explicit dependency variant would be additive. No dependency references, scheduler concurrency cap or repeat construct exists in this public type. | +| `packages/core/src/workflow/types.ts:33-54` | Workflow owns initial state, steps, optional continue/stop policy, version/validator pair, retry policy, event bus and checkpoint store. | Leave ordinary defaults intact. A new graph option must be opt-in and validated before dispatch. | +| `packages/core/src/workflow/types.ts:56-74` | Results expose state, `StepResult[]`, optional completed/failed status and a fixed workflow failure reason; step statuses are done/error/skipped; incomplete child output is retained as evidence. | Preserve existing result shapes and status meanings. Node diagnostics can reuse step results where sufficient; do not turn partial child output into a successful state patch. | +| `packages/core/src/index.ts:546-564` | Workflow checkpoint/error classes, every public step type, configuration/result types and `Workflow` are explicitly root-exported. | Any new public graph type/error needs the same explicit root export and packed declaration coverage. Deep source imports are not a public package entry. | +| `packages/core/src/workflow/checkpoints.ts:8-27` | Checkpoints store a top-level absolute index, ordered top-level names, definition version, state/results and lineage. | This is a linear completed-boundary cursor, not an arbitrary DAG frontier or active-node journal. | +| `packages/core/src/workflow/README.md:3-9` | Owned patches, declaration-order joins, optional strict conflicts, shallow snapshots, failed children and cancellation are documented. | Graph state visibility and conflict rules must be explicit; preserve mutation/isolation limitations unless the implementation deliberately changes them with evidence. | +| `packages/core/src/workflow/README.md:11-21` | Conditions/parallel groups form top-level checkpoint boundaries. Strict continuation validates identity/version/state, clones state, uses fresh caller context and may execute later effects again. Adapter is non-durable. | A graph group can reuse this boundary; mid-group/active-run recovery and exactly-once effects remain separate work. Hosts must bump definition version when dependency edges/callables/captured dependencies change. | +| `packages/core/src/agent/types.ts:83-87,200-226,278-285` | Agent has finite configurable tool-roundtrip/output limits; caller options carry services, signal, identity and mode; results distinguish stopped/error/cancelled/partial with reasons. | Graph nodes should call the ordinary Agent path with unchanged caller authority and bounds. Do not implement an alternate model/tool loop. | +| `packages/core/src/agent/execution-services.ts:17-20,28-66` | Neutral host port owns model/stream calls, effect dispatch, settled-tool observations, owned work and conversation records. | Preserve the core/harness separation and use this port for every controlled graph operation. | +| `packages/harness/src/drivers.ts:19-35,111-152` | `workflowDriver` accepts `Workflow`, forwards caller options/services, merges a JSON input patch and maps aggregate failure; capabilities are local, controlled and non-durable. | Reuse this adapter when the new capability lives on Workflow. Do not widen durability/control claims. | +| `packages/harness/src/runtime/driver.ts:146-181` | `ExecutionDriver` has identity/version/capabilities and one `start(request, services)` method. | No driver resume hook or active-node recovery contract currently exists. A graph API does not create one. | +| `packages/harness/src/runtime/driver.ts:182-215` | Harness services add shared budget snapshot, host control/finish model calls, history, events, input, scoped resources and artifacts. | Host policy/planning/verification calls and graph children must consume the same run budget; no private graph service stack. | +| `packages/harness/src/runtime/budget.ts:16-43` | Aggregate model, tool, token and revision limits; logical model calls are explicitly distinct from SDK/HTTP retries; unknown usage is visible. | Preflight all concurrent/repair work; report reservations and unknown usage; do not present logical-call counts as physical-attempt counts. | +| `packages/harness/README.md:265-298,313-320` | Single terminal result, cancellation waits for owned work, no rollback, shared reservations, controlled function effects and no automatic controlled retries. | Graph scheduling must obey the same lifecycle/effect/retry ownership. A graph cap cannot weaken global budgets. | +| `packages/eval/src/types.ts:3-5,32-68` | Structural `EvalTarget.run`, output-preserving evaluation results, explicit infrastructure/grading fields and ordinary suite configuration. | An existing Workflow harness target can use eval without new concrete graph/Agent coupling. | +| `packages/harness/src/testing.ts:79-96,120-166,204-245` | Framework-free testing seam accepts any runtime config/driver; fixed host identity, restricted caller overrides, per-run isolation, bounded tool observation and budget/native-status diagnostics. | Reuse `createHarnessEvalTarget` from the testing subpath. Failed/cancelled observation is partial; absence of observed forbidden effects is not proof of absence. | + +## Compatibility decisions that need an explicit specification + +1. **Definition identity and validation.** Stable unique node names, known dependency references, nonempty valid IDs, cycle policy and finite concurrency/repeat limits must be validated before any node effect. Today's graph-less contracts do not supply these rules. Validate external checkpoint state through the existing validator; a TypeScript assertion cannot validate restored input. +2. **State visible to a newly ready node.** The spec must choose deterministic dependency-derived state or a clearly defined shared-state policy. Dispatch/settlement order must not silently determine whether a node sees unrelated sibling writes. Reuse owned patches; preserve deliberate same-value writes and replace nested objects rather than mutate shared references. Do not introduce a reducer framework merely to implement the existing merge rules. +3. **Branch and join readiness.** Existing conditions may produce skipped work; a graph join must not wait forever on an excluded branch. Define exactly which selected/completed prerequisites admit a successor, what a skipped prerequisite means, and which descendants are skipped after failure. An “all settled” join must not treat a failed required input as successful evidence. +4. **Failure policy compatibility.** Ordinary Workflow `continue` still runs later serial work after a collected error. For dependency nodes, continuing independent work does not imply running consumers of failed required prerequisites. Define this distinction without changing existing serial callers. Already-started siblings settle and successful owned patches may survive ordinary failure; strict structural conflicts remain fatal. +5. **Result diagnostics at the adapter seam.** `workflowDriver` serializes `result.state` and returns that state as `structured`; it currently discards the detailed `stepResults` from its public driver output (`drivers.ts:137-151`). It also maps workflow cancellation to empty text (`drivers.ts:128-134`). Tests may inspect direct Workflow results and a complete host ledger; eval cannot infer node attempts, blocked dependencies or repair counts from final state alone. Add bounded optional diagnostics only if a real public consumer requires them; avoid making new graph metadata mandatory state fields. +6. **Continuation boundary.** Reuse v2 checkpoints only for an entirely completed graph group or a validated serialized top-level boundary. They cannot encode an arbitrary completed node set/ready frontier. Restoring inside a group requires a separate versioned contract and effect-reconciliation design. Graph changes inside a stable named group must bump `definitionVersion`, because the existing ordered-name binding cannot detect edge/callable changes. +7. **Retry ownership.** Ordinary standalone retry and controlled acknowledgement handling differ. Graph retries must not multiply Workflow retry, Agent retry and provider SDK retry layers, or rerun an acknowledgement-unknown effect. Host operation intent/receipt reconciliation remains required for uncertain external outcomes. Keep partial outputs/attempt records even when a subsequent repair succeeds. +8. **Public consumption.** Core and harness ship ESM/CJS with separate `.d.ts`/`.d.cts` exports (`core/package.json:23-37`; `harness/package.json:22-48`). Core ships the workflow contract (`core/package.json:81-84`). New public types/docs must resolve through those packed entries; no workspace aliases, mandatory harness/eval import in core-only usage, or new graph dependency should be necessary. + +## Existing validation assets to extend + +All items below were inspected, not executed during this investigation. + +| Fixture/source | Existing assertions useful for graphs | +| --- | --- | +| `packages/core/src/workflow/__tests__/workflow.test.ts:54,127,176,228,259,295,318` | Serial state, Agent input/output, selected/omitted conditions, parallel concurrency/partial failure and standalone retry. | +| `packages/core/src/workflow/__tests__/integrity.test.ts:23-81,83-190` | Both settlement orders; only owned patches join; same-value writes and declaration ordering; nested strict conflict waits for started work; partial child results; successful sibling patch plus stop policy. | +| `packages/core/src/workflow/__tests__/integrity.test.ts:193,208,232,256,284,328,360,381` | Cancelled child, late patch after abort, abortable backoff, no retry after uncertain controlled acknowledgement, documented shallow mutation, no checkpoint after strict failed join, late Agent output and nested stop. | +| `packages/core/src/workflow/__tests__/continuation.test.ts:58-92,145,253,295,303,323` | Repeated absolute continuation with cumulative results/lineage; rejection before effects for identity/version/order/cursor/state mismatch; caller identity/services; noncloneable state; strict/legacy compatibility; cancellation and failed checkpoint save. | +| `packages/harness/src/__tests__/drivers.test.ts:303,326,363,400,418` | Truthful stopped loops; initial state patch and scoped approvals for function effects; denial prevents callback; external driver conformance; resource cleanup. | +| `packages/harness/src/runtime/__tests__/execution-drivers.test.ts:52,66,74,145,216,288,312,443,475,505` | Single terminal result, pre-start cancellation, quiescence before resource release, unsupported durability, concurrent call reservation, revision effects disabled, bounded revisions and late settled usage. | +| `packages/harness/src/testing.ts:21-76` | `testDriverContract`: one fixture invocation, terminal/result equality, ordered event identities/cursor, immutable settled result and resource cleanup. It is a smoke contract, not proof of every graph behavior. | +| `packages/harness/src/__tests__/eval-target.test.ts:48` and `packages/eval/src/__tests__/target-contract.test.ts:14,33,62,90` | Actual settled-tool observations and bounded coverage; structural target and ordinary Agent compatibility; cancellation/session ownership. | +| `packages/eval/src/__tests__/result-integrity.test.ts:340,374,397` and `packages/eval/src/case-lifecycle.ts:166-223` | Preserve generated output when grading fails; explicit incomplete/infrastructure coverage and valid-grade denominator; no regeneration merely because judging timed out. | +| `packages/harness/src/__tests__/context-memory-acceptance.test.ts:385-407,593-624,634-638,832-855` | Existing pattern for versioned paired fixtures, isolated same prior tasks, preparation costs, exact metrics/denominators, unknown usage and an infeasible baseline that is reported rather than dropped. This is a methodology pattern, not a graph fixture or graph performance result. | +| `packages/harness/src/__tests__/package-consumption.test.ts:41-125,164-196,198-305,313-408` | Explicit post-build packed gate, core+harness with/without eval, absent optional SDKs, offline ESM/CJS execution, strict NodeNext `.ts`/`.cts` compilation and ordinary core-only execution. Add graph imports/typed states/execution to these existing paths. | + +The standard package suite skips packed checks unless `AGENTIUM_TEST_PACKAGES=1` (`package-consumption.test.ts:11,42,313`); a passing source suite cannot establish packed compatibility. Existing historical gate reports are not evidence that an unimplemented graph capability passes. + +## Proposed acceptance cases + +Use deferred gates and complete host effect/attempt ledgers rather than real-time sleeps for ordering assertions. These are proposed checks, not passing results. + +| Case | Setup and observable acceptance | +| --- | --- | +| G01 — Independent overlap | Two ready nodes enter before either gate is released. Enforce a declared concurrency cap; with cap 1 the second cannot enter until the first settles. Final state contains both owned patches in both settlement orders. | +| G02 — Cross-dependency benefit | A/B start; C depends on A; D on A/B; E on C/D. Release A while B is blocked: C enters. Hold C and release B: D enters. E enters only after C and D settle. Each primitive task runs once. This rejects a topological-level barrier and supplies the concrete reason to add graph scheduling. | +| G03 — Definition validation | Duplicate node names, dangling/self dependency, unsupported cycle, malformed/zero/negative/nonfinite concurrency and invalid repeat bounds reject before the host ledger records an effect. Valid forward references work if the final contract permits them. | +| G04 — Branch and join | Run both outcomes of the same input predicate. Only selected branch effects execute. Excluded work is explicitly skipped; the join executes exactly once after the required selected results and never deadlocks waiting for an excluded branch. Predicate reads a documented state snapshot. | +| G05 — Deterministic input visibility | Reverse independent settlement order while keeping dependencies/results fixed. Each dependent sees the same declared prerequisite state and final output is identical. Unrelated branch mutations cannot nondeterministically alter a dependent's input. | +| G06 — Bounded successful repair | One node uses the ordinary Agent loop/explicit bounded repair to produce an invalid candidate once, then a valid candidate. Host verifier accepts current evidence. Attempts and their costs remain visible; consumers start once after verified success; no already successful sibling repeats. | +| G07 — Repair exhausted | Always-invalid fixture reaches the declared repair/Agent-roundtrip cap and stops with an explicit reason. No downstream consumer treats the final partial candidate as successful state. Graph-native cycle rejection remains separately tested if first version has no repeats. | +| G08 — Shared budget exhausted | Under a two-call aggregate limit, multiple ready nodes attempt model admission; at most two reach the fake provider. Every retry, planning/control/verification call shares the ledger. No successor starts a denied operation, remaining reservations reach zero after settlement and unknown usage is reported when injected. Repeat with tool and token ceilings. | +| G09 — Cancellation before dispatch | Already-aborted caller signal executes no callback/provider/tool and yields one cancelled terminal result in harness. Direct Workflow uses its existing cancellation error contract. | +| G10 — Cancellation in flight/backoff | Abort while one sibling is blocked and another is ready, and during repair/backoff. No new admission follows known abort; late patches/checkpoints/completion do not publish. Already-started work/settled observations complete before resource/session release. Terminal outcome stays cancelled; applied effects and usage remain evidence. | +| G11 — Partial failure, continue | A required node fails/stops with partial output; its consumer is blocked/skipped under the chosen dependency policy. An unrelated branch finishes. Aggregate result is failed, partial child output remains diagnostic and successful sibling patches survive. Existing serial continue behavior remains unchanged. | +| G12 — Partial failure, stop | With stop policy, no newly ready downstream work dispatches after the failure is known. Already-started siblings settle. No successful terminal result is inferred from some successful branches. | +| G13 — Retry owner and unknown acknowledgement | A controlled effect applies then loses acknowledgement. Workflow/graph does not retry it automatically, even with standalone retry configured. Ledger records one intent/attempt and an unknown outcome; caller cannot resume/retry that in-flight boundary as though it were safely completed. A separate known pre-effect transient fixture follows only the declared retry owner/bound. | +| G14 — Conflicting state | Incomparable nodes return the same owned key, including a deliberate write of its original value. Default collision outcome follows the documented declaration rule independent of timing. Strict merge throws the existing typed conflict, applies none of the failed join's patches, writes no checkpoint for that join and admits no consumer of that invalid joined state. The fixture also documents existing shallow nested-reference limits. | +| G15 — Safe completed boundary | Complete a whole graph group, save validated v2 state, then continue the next top-level step. Completed group effects do not repeat; later effects execute afresh. Continue a continuation and verify absolute cursor/results/lineage. Alter version, names, state or cursor: reject before effects. Cancellation/strict conflict/save failure never produces a successful boundary. | +| G16 — Ordinary caller parity | Existing `new Agent(...).run/stream` and existing serial/condition/parallel Workflow callers retain outputs/statuses, lifecycle, state conventions and limits without adopting graph definitions. One Agent node preserves ordinary node behavior; wrapper JSON Workflow output is normalized explicitly for comparison rather than silently changing the old adapter return shape. | +| G17 — Authority and observation | Denied function/node/tool effects never invoke the callback. Node Agent calls receive verified identity, signal, immutable run mode and the same execution services/grants. Bounded/failed/cancelled observation is marked incomplete; it cannot pass “no forbidden effect” from silence. | +| G18 — Packed/public compatibility | Fresh packed core-only, core+harness and optional-eval consumers compile and run a typed graph fixture through ESM/CJS plus `.ts`/`.cts`. They import from root/testing exports only and run without graph DB/library/provider SDKs. Retain the preexisting ordinary core-only case. | + +G02 must establish more than the existing parallel-group tests. G04/G05/G11/G14 require the graph state/readiness semantics to be decided before implementation; this table intentionally makes those design obligations visible. + +## Feasible measured loop-versus-graph comparison + +Use two complementary comparisons. The first isolates the scheduler's behavior against an equivalent structured Workflow baseline. The second compares the ordinary bounded Agent loop with explicit Workflow orchestration under identical task definitions and host budgets. Neither can establish live-model reasoning quality from recorded responses. + +**Versioned deterministic manifest.** Add a proposed `execution-graphs-eval.v1` fixture beside the existing harness acceptance fixtures, with fixed task IDs, dependency manifests, inputs, primitive tool implementations/results, injected failures/gates, provider snapshot identifier, prompts/schemas, declared usage, budget/cap/repair limits, expected effects and exact outcome labels. Labels live outside agent-visible input. Use isolated stores/resources/session IDs and reset every scripted provider/ledger between conditions. Key fake provider responses by task/purpose/attempt, not a global request index; scheduling order must not change which task gets which answer. + +**Common task execution.** Both conditions call the same primitive task implementation and, where tasks need reasoning, the same bounded Agent/provider configuration through the same `ExecutionServices`. The loop uses existing `agentDriver`; explicit orchestration uses the existing `workflowDriver`. Give the loop the same task/dependency information that is encoded in the graph; do not grant the graph a hidden gold plan. Do not restrict the loop's existing ability to request multiple independent tools. Any additional loop planning calls or graph wrapper-effect admissions are measured as actual overhead and consume the same envelope; do not conceal unequal overhead by comparing node-only counts. Preserve the same permitted logical effect set and document any necessary wrapper grant names. + +**Small initial workload.** Use a straight chain, independent fan-out, the G02 shared-prerequisite DAG, branch/join, one-successful-repair, repair exhaustion, cancellation, strict conflict, uncertain acknowledgement and completed-boundary continuation: ten paired scenarios. Configure both conditions with the same finite `maxModelCalls`, `maxToolCalls`, `maxTokens`, `maxRevisions`, Agent roundtrip/output limits and cancellation deadline; use a declared maximum graph concurrency of 2. A reasonable fixture envelope can start at 12 logical model calls, 12 tool/effect admissions and 16,000 declared total tokens per case, provided fixture preflight proves both sides' intended successful traces fit. These are proposed fixture ceilings, not optimal production settings or authorized live spend. Run each pair in both controlled settlement orders for 40 condition executions; deterministic repeats test ordering invariance, not statistical model variance. No judge model or paid calls are needed. + +**Measurements and exact checks.** Record normalized task success/final state; dependency violations; forbidden/duplicate effects; node/task/repair attempts; started/completed/skipped/blocked counts; statuses and reasons; model calls; tool/effect admissions; declared/reported tokens; peak simultaneous task/provider calls; remaining/reserved budget; unknown usage; cancellation and cleanup coverage. Count orchestration/planning/verification separately from primitive task work while including all of them in totals. Preserve raw outputs and complete ledger traces, including failures. `createHarnessEvalTarget.observation()` supplies budget/native status/tool coverage; collect graph task boundaries using a test-owned complete ledger because `workflowDriver` does not expose detailed step results in its output. The existing eval suite's `total`, `gradedCases`, `infrastructureFailures` and output-retention fields can preserve coverage; exact host checks should be ordinary deterministic scorers, not an LLM judge. + +**Timing.** Use virtual gate schedules to report fixture critical-path/overlap behavior and verify G02. Clearly label any synthetic duration as fixture scheduling latency. If a local benchmark is later authorized, use the same fixed gate/delay workload and report measured orchestration wall-time overhead separately, predeclare repeats and retain every run; do not interpret fake-provider delay differences as live model throughput. Real provider latency, billing and task quality remain unmeasured here. + +**Decision contract.** Any forbidden effect, dependency violation, duplicate unknown-outcome effect, leaked reservation, false successful partial result, cancellation admission or unsafe checkpoint restoration blocks irrespective of averages. Every successfully executable baseline task must retain the exact normalized outcome under graph orchestration. The graph should demonstrate the G02 overlap without duplicate primitive work. Report per-case call/token/overlap differences and graph overhead; do not assume an improvement beforehand. An infeasible baseline or missing/incomplete observation is explicit coverage, not a dropped denominator or pass. The fixture suite demonstrates covered SDK invariants and structural overhead, not model superiority, production reliability percentages or release readiness. + +Live model comparison is a later separately bounded experiment with pinned snapshots/sampling/tool versions, matched prompts/tasks/budgets, predeclared repeated paired cases, calibrated outcome scoring and an uncertainty/inconclusive policy. No live result or speed/cost advantage is claimed in this inventory. + +## Challenge notes for the parent candidate contract + +Candidate supplied during this investigation: additive `GraphStep.graph` accepts a node array or synchronous state-derived factory; `maxNodes` defaults to 100, `maxConcurrency` to 5, and new graph merge defaults to `error` with `declaration_order` available. Nodes have `id`, existing `StepDef`, control `dependsOn` and data `inputsFrom`; control prerequisites admit done/skipped, while data prerequisites require done and contribute transitive data-ancestor patches. Additive `RepeatStep` has nested steps, a `(state, iteration)` predicate and positive finite `maxIterations`. Generated executable steps remain host-authored/registered; services/budgets and outer checkpoint boundaries are reused. This is still a proposal, not implemented or verified behavior. + +This candidate stays within the existing ownership architecture. The following details should be frozen before tests/implementation: + +| Gap | Required observable rule/acceptance addition | +| --- | --- | +| Data-only reference readiness | `inputsFrom` contributes a dependency even when the same ID is absent from `dependsOn`. Validate missing references/self references/cycles over the union of control and data edges before any generated node effect. Test a blocked data-only predecessor and a cycle spanning one control plus one data edge. | +| Skipped/error prerequisites | Done/skipped control readiness and done-only data readiness are separate and must be documented. A skipped data ancestor blocks/skips the consumer; an error predecessor never admits a success-requiring consumer. Run true/false conditional predecessors for both edge kinds and retain the reason for skipped descendants. | +| Node identity versus step name | Existing state and effect/diagnostic names are based on `step.name`, not the proposed node `id` (`types.ts:64-70`; workflow README:3; harness README:315). Unique node IDs alone do not prevent duplicate `${step.name}_output`, ambiguous step results or ambiguous `workflow:` grants. Require an unambiguous scope/mapping and test duplicate step names under different IDs without changing ordinary step naming. | +| Ancestor patch provenance | A shared ancestor reached by two `inputsFrom` paths must contribute its owned patch once. Copied/transitive state snapshots are not additional writers. Test A feeding B/C and both feeding D; D must not raise a false A-versus-A conflict. | +| Ordered versus incomparable writes | Decide whether strict conflict covers incomparable writers only, or all distinct writers even when explicitly ordered. Intentional successor overwrite of an ancestor key must have a documented usable path. Test A writes `n`, B consumes A and writes `n`, versus independent A/B writes. State visibility and final-state ordering must not depend on settlement timing. | +| Changed merge default | New graph default `error` is an opt-in graph contract, while existing parallel default remains declaration order. Run both forms side by side in public/packed fixtures and document that distinction. | +| Materialization bounds | Validate array/factory output, `maxNodes` and `maxConcurrency` as finite safe integers before generated effects; reject unsupported asynchronous factory output. The cap applies to each materialization and the design must disclose the overall finite bound from nested repeats/materializations. Do not hide potentially large products of iteration/node limits, and never reset global model/tool/token budgets. Test factory output at and above the cap on a later iteration. | +| Repeat entry/exit/cap | Define iteration numbering and predicate timing. A false entry predicate executes zero children. After the last permitted iteration, false means normal completion and still true means explicit exhaustion, with no extra child admission. Reject nonboolean runtime predicate output. Test exactly-at-cap success, always-true cap exhaustion, predicate throw, cancellation and child failure. | +| Repeat outcome propagation | Existing public Workflow aggregate reason is typed only as `workflow_step_failed` (`types.ts:58-59`) and the adapter only specially catches cancellation (`drivers.ts:128-134`). Choose how an explicit repeat-limit code remains available through direct Workflow and harness/eval without changing existing status meanings. It must not become completed or a message-only reason that callers must parse. | +| Repeated identity/effects | Retain unambiguous node/iteration/attempt observations while repeated logical names remain stable for host grants. An intentional new iteration and retry of one acknowledgement-unknown intent are different; only the host can authorize/reconcile the latter.

Existing ToolExecutor already runs a model's independent tool batch concurrently, so the implementation does not add a second Agent planner or tool scheduler. The new graph is valuable when stages have declared dependencies, state ownership, branches or joins. A single existing Agent loop remains appropriate for exploratory work without those stage boundaries. + +This decision follows the papers' execution patterns and Agentium's actual interfaces. ReAct supports local reasoning and action after observations. OpenHands separates agent decisions, event history and runtime execution. LLMCompiler separates dependency planning from readiness scheduling, allows tools that are agents, and replans between episodes. The choice to reuse Workflow, enforce owned patches and retain boundary checkpoints is engineering judgment; these papers do not establish Agentium's cancellation, retry, durability or effect guarantees.

A predecessor may finish done or skipped. `inputsFrom` also controls scheduling and supplies data; its producer must finish done. Failed or blocked predecessors block their consumers. +- Each node receives a structured clone of graph entry state plus patches from its transitive data ancestors. Completed siblings and control ancestors do not silently become inputs. Graph state and returned patches must be structured-cloneable. +- Complete episodes are validated before node dispatch: identifiers, step shapes, references, duplicate edges, mixed-edge cycles, limits and node counts. Identity validation includes well-formed Unicode before path encoding. +- Scheduling is incremental. In `A/B; C <- A; D <- A,B; E <- C,D`, C can start while B is still running. Results and joins use stable topological order with declaration-order ties, independent of settlement order. +- Strict merge is the default: incomparable nodes owning the same state key conflict, including equal-value writes. Ordered descendants may overwrite ancestor keys. The explicit `declaration_order` option uses stable topological order with declaration-order ties. +- Ordinary node failure retains child diagnostics and successful independent patches; its own patch is discarded and dependent work is blocked. Definition, merge and cancellation failures stop admission, drain started work and reject the boundary. Effects already executed are not rolled back. +- Graph defaults are five concurrent nodes and 100 nodes per episode. Repeat requires a positive safe integer cap, captured before callbacks run. It reports `workflow_iteration_limit` if the condition still requests work at that cap. Static and dynamic composition are depth-bounded. +- A graph factory inside a repeat selects the next episode from settled observations. Factories and predicates are trusted host callbacks; the SDK does not execute arbitrary model-generated code or provide an autonomous planner. +- Scoped paths identify nodes and iterations in results, events, effect names and Agent child sessions. Existing Agent output keys remain `_output`. Node and tool content remains data under host instruction authority. + +The harness integration also corrects an existing budget admission defect. Root `dispatch` and `dispatchEffect` previously passed distinct wrapper/underlying policy identities to ToolExecutor even though both delegated to one shared budget. One operation could consume two admissions, preventing an effect with an exact budget of one. Both ports now reuse `ctx.executionPolicy`; separate local-policy composition and host denial remain enforced. Four direct regression cases cover these behaviors.

The report remains unchanged so its original verdict and evidence are visible. The coordinator reproduced all three in failing regression tests, corrected them at `2896f397fd766fca9fafac0e4c249de36f10609f`, and verified the corrected revision.

Its [RED](evidence/identity-red.log), [regression](../../packages/core/src/workflow/__tests__/execution-graphs.test.ts#L16) and final 141-case GREEN are retained; the fix is in `0fd732c`. Final types and all broader gates cover that revision. No material finding remains unresolved. + +## Matched offline comparison + +The [comparison script](../../scripts/compare-execution-graphs.ts) runs three paired tasks through the public Agent and Workflow harness adapters under the same task manifest, offline provider implementation, tool, grants, resource budgets and Agent limits. Each condition has isolated state. Both use budgets of 16 model calls, 16 tool admissions, 128 tokens and zero revisions; per-Agent limits are four tool roundtrips and four output tokens. The graph uses concurrency two. The existing loop may batch independent tools. + +| Task | Loop model calls / tokens | Graph model calls / tokens | Tool admissions in each | Loop / graph local time, ms | +| --- | ---: | ---: | ---: | ---: | +| Chain | 4 / 12 | 6 / 18 | 3 | 66.383 / 3.608 | +| Fan out | 3 / 9 | 6 / 18 | 3 | 1.361 / 28.376 | +| Cross dependency | 4 / 12 | 10 / 30 | 5 | 7.279 / 4.219 | + +All six executions returned their independently specified output with no duplicate effects, dependency violations, unknown usage or outstanding model/token reservations. Offline provider charges were $0; production billed cost is unknown. The graph used more model calls and tokens here because each task contains an ordinary Agent loop. This supports explicit coordination, not a cost reduction claim. + +These are one-run deterministic fixtures with zero simulated provider latency. Local times include startup, order and CPU effects; they do not estimate production latency or a speedup. Very short graph tools did not overlap in this comparison, while the separate gated harness case demonstrates concurrent Agent tool work and incremental readiness. There is no live-model quality, variability or billing result, and none of the papers' benchmark gains is attributed to Agentium. + +## Compatibility, host ownership and deliberate limits + +No dependency, package version or lockfile was changed. Existing serial, condition, parallel and Agent callers remain supported and pass checks. Graph and repeat behavior is opt-in. The additive `StepDef` variants and `workflow_iteration_limit` reason may require consumers with exhaustive union handling to recognize the new cases. New graph state must be cloneable, and hosts must grant the scoped effect names shown in the guides. + +Checkpoint continuation covers completed top-level graph/repeat boundaries. A saved successful boundary is skipped on continuation, but a crash or save failure can repeat an unsaved whole boundary. There is no mid-node or mid-iteration resume, recorded model/tool playback, exactly-once external mutation or atomic remote receipt. Scope paths are diagnostics, not idempotency keys. The existing workflow driver still advertises `durable: false`. Hosts own storage, definition versioning, resource locks, idempotency and reconciliation; changing factory/code/dependencies requires an appropriate definition version. + +Cancellation is cooperative and waits for started callbacks to settle. Graph concurrency bounds nodes, not all nested tool calls. Shared-budget admission winners can depend on timing, and nested local graph/repeat limits do not constitute a single global expansion ceiling. Graph cloning protects input/patch data; it does not sandbox trusted callbacks, captured resources or mutable host context. Dependency independence alone does not prove shared external resources can safely run concurrently. + +A second Agent tool-DAG planner, streamed live topology changes, a durable per-node adapter and production performance evaluation are deliberately deferred. They are not blocked pieces of the selected design. The detailed [design](design.md), [research comparison](research.md), [runtime inventory](runtime-inventory.md), [SDK/evaluation inventory](sdk-eval-inventory.md), [completed plan](plan.md) and [decision ledger](decision-ledger.md) explain the boundaries and review rulings. + +The task used the suitable attached dependability worktree and parallel experts with disjoint file ownership; the coordinator integrated shared files and owned commits. Separate concurrent edits in `/Users/xerycks/Xhip/agentium` were neither imported nor reset. At the last [audit](evidence/original-audit.json), that checkout had changed independently across 78 captured paths and was on `main`.

This report is the reviewer's only written file. No implementation, index, branch, build, install, commit, paid call, external effect, or subagent work was performed. + +Inputs: the original user attachment, `plans/execution-graphs/design.md`, `plan.md`, research and contributor reports, the progress ledger, complete branch diff, changed implementation/tests, and neighboring Workflow, RunContext, ToolExecutor, harness driver and checkpoint contracts. Applied the original checkout's code-review and TypeScript skills and requesting-code-review reviewer instructions. No applicable AGENTS.md was found in the checked checkout/ancestor paths. + +## Strengths + +- The change extends Workflow/StepRunner and reuses Agent, ToolExecutor, ExecutionServices, workflowDriver and the existing evaluation target. There is no competing runtime or new dependency. +- Scheduler control ancestry and data ancestry are separate. Input snapshots, owned patches and final results use a stable topological order, while the documentation correctly limits deterministic claims around shared-budget admissions and effects. +- Complete static episode validation, graph clone isolation, strict incomparable-write conflicts, transitive blocking and cancellation draining are coherent and receive focused coverage. +- The root dispatch/dispatchEffect policy identity fix is justified: ToolExecutor intentionally composes distinct context/local policies, and both original root identities delegated to the same budget-owning policy. Reusing `ctx.executionPolicy` removes duplicate admission without removing host policy/grant enforcement or distinct local-policy composition. +- Checkpoint schema changes retain the additive path/reason fields. The docs keep completed-boundary continuation distinct from recorded replay, mid-graph recovery and remote-effect safety. The adapter remains `durable: false`. +- The paired offline comparison retains independently specified expected outputs and reports exact outcomes, calls, tokens, reservations and zero offline charges without claiming production speedup or real-model quality. + +## Standards and correctness findings + +### F1 — P2: Snapshot the validated repeat limit before callbacks execute + +Location: `packages/core/src/workflow/step-runner.ts:332` and `:336` (validation at `:319`). + +`maxIterations` is validated once, but the loop reads the mutable `step.maxIterations` again after every predicate invocation. A predicate, body callback, or concurrent reuse of the host-owned definition can increase the limit after validation. This defeats the advertised bound and can even turn it into Infinity. Graph execution already captures its validated limits before invoking callbacks. + +Confirmed trigger: start with `maxIterations: 1`; the predicate sets the same definition's limit to 3 and returns `iteration < 3`; the body increments a counter. The actual result was three body applications and `status: completed`, with no iteration-limit reason. The initial validated bound was one. + +Impact: the SDK's structural safety limit can silently permit additional effects and work. Host-owned executable callbacks are trusted, but that does not make rereading mutable configuration a reliable execution bound. + +Correction: capture the validated limit in a local before calling the predicate or body; use that same value for admission and exhaustion reporting. Add a regression that mutates the definition during execution and verifies the entry limit remains effective. + +Confidence: high; reproduced directly against source at the reviewed head. + +### F2 — P2: Prefix only results synthesized by the current graph invocation + +Location: `packages/core/src/workflow/step-runner.ts:296`–`:298`. + +The scheduler returns flattened child results. The wrapper prefixes every result with a dependency-blocked/node-failed reason, including results that were already fully scoped by a nested GraphStep. Each ancestor graph consequently prepends its own scope a second time. + +Confirmed trigger: an `outer` graph has node `node`, whose `inner` graph contains a skipped condition `skip` and a data-dependent `blocked/consume` node. Other nested paths were correct, but the blocked result was: + +```text +actual: outer/outer/node/inner/blocked/consume +expected: outer/node/inner/blocked/consume +``` + +Impact: valid nested graph failures report nonexistent execution locations, lose reliable correlation with the corresponding node/event identity, and persist the corrupted path in checkpoints. Additional nesting compounds the error. This matters especially when step names repeat and executionPath is the distinguishing diagnostic key. + +Correction: assign full paths when synthesizing current-scheduler results, or otherwise distinguish those rows from already scoped callback results. Do not identify path ownership solely by reason code. Cover nested blocked descendants and a checkpoint round trip. + +Confidence: high; reproduced directly against source at the reviewed head. + +### F3 — P2: Preserve accumulated repeat evidence when a later predicate throws + +Location: `packages/core/src/workflow/step-runner.ts:332`; generic catch at `:124`–`:139`. + +An ordinary exception from a repeat predicate escapes the repeat method and reaches the generic whole-step catch. That catch returns the repeat's entry state, an empty patch, and just one error result. It discards all completed iteration results and state already accumulated by the repeat. Body failure and iteration exhaustion correctly retain that accumulated information, so a predicate failure has materially different and surprising semantics. + +Confirmed trigger: iteration zero runs an effect, returns `{n: 1}`, and completes; `while(state, 1)` then throws `Error("predicate failure")`. The actual result was: + +```json +{ + "completedEffects": 1, + "state": {"n": 0}, + "stepResults": [{"stepName": "repair", "status": "error", "error": "predicate failure"}] +} +``` + +Impact: direct Workflow callers lose the successful child's result/path and receive stale state even though its effect already executed. With the default continue policy, later serial steps consume that stale state; checkpoint execution can save the failed boundary without the completed iteration evidence. A nested graph can still atomically discard a failed node's patch, but it should retain the child's completed diagnostics. + +Correction: handle ordinary predicate exceptions inside repeat execution, returning the current accumulated state/patch/results together with the repeat error, as the existing body-error branch does. Preserve the current escape/drain behavior for cancellation and fatal definition/merge errors. Add a regression after at least one completed iteration, including downstream state/evidence assertions. + +Confidence: high; reproduced directly against source at the reviewed head. + +## Specification verdict + +The chosen explicit Workflow DAG with bounded Agent nodes and repeat episodes is a justified implementation of the user objective. The change covers the requested architecture comparison and engineering decisions; distinguishes control edges from data dependencies; reuses the existing runtime, controlled effects and shared budgets; supplies branching, joins, finite episodes and observation-driven replanning; preserves old entry points; and documents the durability/effect limits and host responsibilities. + +No separate missing architecture feature was identified. A second model-generated tool-plan scheduler, streamed topology replacement and per-node durable resume were considered during design and reasonably deferred, rather than silently omitted requirements. The user explicitly allowed the best justified design and verification “where supported by the chosen design.” The existing ToolExecutor already handles concurrent model tool batches, and the new incremental DAG demonstrates a capability beyond serial/parallel grouping. + +The implementation is not yet fully conformant with the selected contract: F1 contradicts the advertised validated repeat bound, F2 contradicts scoped nested node identity, and F3 weakens the lifecycle/partial-failure evidence contract. These are implementation corrections, not reasons to replace the architecture. + +## Verification and evidence scope + +Independent execution was limited to three focused read-only probes using source imports: + +```text +TSX_DISABLE_CACHE=1 node --import tsx --input-type=module +``` + +The stdin program imported `packages/core/src/workflow/workflow.ts`, instantiated unregistered Workflows, and ran only local counter/no-op callbacks. It reproduced F1, F2 and F3 with the outputs recorded above. No fixture files or caches were written by the probes. + +Reviewed test coverage includes the scheduler's invalid IDs/edges/references/cycles/limits/step shapes/static recursion, stable-order joins and same-value writes, transitive data-only visibility, nested error patch rejection, cancellation/late settlement, dynamic factory isolation, encoded Agent session identity, core checkpoint continuation, harness shared budgets/host authority/cancellation/retry behavior, and packed ESM/CJS/.ts/.cts consumer additions. + +The coordinator reported 123 core workflow tests plus core types, ten harness graph tests and four exact-budget regressions passing before this review. Those are supplied verification evidence, not tests independently rerun by this reviewer. Full builds, monorepo tests/types, packed consumers and the final comparison rerun remain coordinator-owned and were not duplicated. This report does not claim those broader checks passed. + +## Declined to judge as defects + +- Live-model task quality, production latency and billed cost: the user permits a feasible comparison and the implementation labels its fixture evidence honestly; no paid experiment was authorized or needed for this review. +- Mid-graph resume, recorded playback, remote exactly-once effects and crash reconciliation: the selected boundary-continuation design explicitly excludes them and explains the loss window. No contradictory durable capability claim was found. +- A second Agent tool-plan scheduler or streamed/in-flight graph replacement: the architecture comparison gives a repository-specific reason to defer them, while complete bounded episodes supply the selected replanning capability. +- Aggregate root-tool concurrency, deterministic winners for the final shared-budget admission, and a global total expansion budget across nested graph/repeat steps: the implementation explicitly defines node concurrency, timing-dependent admissions, and multiplied local bounds. This review checked those definitions for contradictions rather than imposing a different scheduler design. +- Isolation of captured host resources, mutable RunContext session state, or callbacks relying on in-place state mutation instead of owned patches: executable callbacks are trusted, and the existing API requires owned patches and host resource coordination. Graph data isolation is not presented as a sandbox. This does not excuse F1's failure to retain an already validated execution limit. +- Bounded shutdown for uncooperative host callbacks: the stated cooperative cancellation contract drains owned started work; it makes no preemption promise. +- Independent revalidation of all paper claims and all pre-existing durable/Agent/ToolExecutor internals: the review read the cited research interpretation and traced changed integration behavior, but did not repeat the dedicated research investigation or audit unrelated baseline subsystems. + +## Assessment + +Corrections are required for F1–F3 before claiming the selected graph contract complete. The architecture and primary scheduler semantics are otherwise coherent; the remaining verification work should target these defects and the coordinator's final integrated revision. No publication or integration action is recommended or performed by this review. diff --git a/plans/execution-graphs/evidence/final-script-types.log

The host owns credentials, MongoDB lifecycle, authenticated tenant/actor admission and receipt retention. `JournaledDurableTaskStore`/`DurableRunRecords` can additionally retain sequenced host audit events; graph state remains authoritative. `inspect(key)` validates without writing or requiring a live lease. `cancel(key, reason)` requests persisted cancellation; active lease polling observes it. Completed tasks return retained output without another dispatch. + +`GraphBinding` supports `tool`, `agent`, `graph` and bounded `repeat`. A controlled function is a catalog `ToolDef.execute`; it has the same schema, grants and recovery boundary as other tools. Agent bindings supply an existing `Agent` and an explicit list of approved catalog tool IDs. Agent output is `{ text, usage }`, validated by the binding's output schema. Nested graph output is a map of node IDs to owned JSON outputs. Repeat guards are versioned, pure host callbacks; their decisions and iteration plans persist before child work. + +## Recovery and effects + +Each task pins its manifest, catalog digest, program/binding versions, original input, policy revision, grants, budgets and absolute deadline. Plans are immutable revision records. Nodes have stable incarnation IDs, input/output digests and fenced attempt records. Completion persists before successor admission. Pending nodes can be claimed; an interrupted running node starts another attempt under a newer lease. Completed output is reused; failed/cancelled nodes remain terminal. Unknown external outcomes require reconciliation before execution resumes. A changed version, input, digest or stale fence fails before resumed effects. + +The runtime copies plain configuration when constructed: static and nested plans, planner bounds, grants, budgets, limits and tool protection data. Later changes to the caller's objects do not change an admitted task. Descriptor checks run again at episode and dispatch boundaries. Opaque schemas, Agent/provider instances and callback behavior remain host bindings; their version must attest those implementations. Sandbox environment values contribute only hashes to catalog descriptors, so planner messages and stored descriptors contain no environment values. + +Interrupted Agents restart from node entry. Complete recorded model responses are reused at the same request-bound positions; their original tool call IDs remain stable. Tool authorization runs again, while stable budget admission IDs avoid charging replay twice. Interrupted model reservations remain conservatively charged as unknown usage. Recovery does not replenish tokens, calls, root allowances or deadlines. + +Durable tools require either `recovery: "pure"` or a recovery object with a versioned `DurableActionConnector`, host-bound destination and immutable `resolveResult(resultRef)`. The action ID binds the node incarnation, tool call, binding and version; the action ledger also binds the actual parsed arguments, destination, policy/grants and identity. Connector dispatch receives those parsed arguments. The SDK never substitutes the original arbitrary tool callback for a declared connector. A confirmed receipt is reused. Acceptance followed by a crash before receipt persistence requires destination idempotency/reconciliation or an explicit recovery-required outcome. A lookup miss alone cannot prove absence. **This does not guarantee exactly-once external execution.** + +Append-only origin evidence selects the exact catalog operation for reconciliation, even when operations share a destination and connector version. Root admission occurs before the ledger marks remote dispatch as executing. A local limit or cancellation rejection therefore remains known not dispatched; it does not invent an uncertain remote effect. The permit covers dispatch and receipt settlement, while confirmed replay and reconciliation need no fresh dispatch attempt. + +The durable catalog rejects undeclared effect policies, result caches and `toModelOutput` callbacks. Agents must have bounded output tokens and supported static configuration; dynamic tool resolvers, handoffs, mutable memory, hooks and other unrecorded behaviors fail preflight. Non-JSON state and undeclared opaque model continuation fail closed. Hosts must bump versions when callbacks, schemas, instructions or execution policy change. The adapter requires stateless harness configuration; existing ordinary HarnessRuntime/Agent/Workflow APIs remain available for other workloads. Existing workflowDriver and checkpoint formats retain their earlier non-durable contract. + +## Root scheduling and limits + +One root slot covers one actual provider request/stream or tool/function callback. Orchestration and preparation hold no slot. Nested graphs, repeat episodes and Agent tools share the same controller, so a parent can wait for children at capacity one. FIFO waits observe cancellation/deadline. Nested controlled dispatch from inside a leaf callback is rejected to prevent hidden oversubscription/deadlock. Streams hold their slot until the iterator closes. Model/tool/token budgets apply in addition to the root limits. Storage I/O, receipt lookups and reconciliation do not occupy dispatch slots. Provider transport retries retain their existing retry owner; one controlled provider invocation counts as one root work attempt. + +Already-owned stream cleanup can run after cancellation through `RootExecutionLease.cleanup()`. It grants no new work or attempt, keeps the nesting guard, and releases the permit only after the iterator finalizer settles. Effect settlement retains its dispatch permit through receipt resolution; other standalone storage reads and reconciliation need no dispatch permit. + +`maxExpandedNodes` counts unique materialized node incarnations across all episodes and replacements. `maxWorkAttempts` counts fresh leaf dispatches, including Agent/planner models and tools. `maxPlanRevisions` counts materialized revision admissions across all episodes. Limits and counters persist before dispatch; removals, interrupted attempts and conservative reservations do not refund allowances. A failed commit may conservatively retain its prior reservation. Cached decisions/receipts consume no fresh dispatch attempt. `onAdmission` and controller snapshots expose queue/admission/release/exhaustion. The ceiling covers controlled SDK work: fencing cannot physically stop an already sent remote request. Its effect evidence must reconcile separately. + +## Optional planning and streamed revisions + +Replace `program.plan` with `program.planner: { provider, hostInstructions, maxCorrections, maxOutputTokens, mode, stream }`. `mode` is `"complete"` (default) or `"stream"`; both use authorized model calls and shared budgets. The planner is tool-free. Catalog/inputs/observations are source data in user messages, while host instructions remain system instructions. The SDK cannot guarantee that a model follows an instruction, but proposal validation and grants prevent unapproved operations from executing. Invalid proposals consume bounded correction attempts. Accepted/rejected proposals, causal observations and planning status remain available in the journal. + +Plans contain unique node IDs, binding IDs/versions, JSON argument templates, `dependsOn` control edges and `inputsFrom` data edges. A reference is `{ "$ref": { "node": "producer", "path": ["field"] } }`. It infers a data dependency. Hosts must declare exact `referenceInputs`/`referenceOutputs` paths and a pure `validateTemplate` for future-valued inputs. Resolve and validate concrete arguments before dispatch. Root program input informs planning; static argument templates refer to producer outputs. Validate the entire candidate for cycles, missing nodes, safe keys/paths, schemas, operation versions, size/depth/concurrency and recovery compatibility. + +`limits.plan.maxDepth` bounds cumulative dependency and nesting depth, including dynamically planned children. Each episode retains its inherited depth, and recovery checks it before models or effects. Repeat iterations consume lifetime expansion and revision allowances; iterations share the same nesting level rather than resetting the limit or adding depth solely because another iteration ran. + +Streaming accepts newline-terminated complete frames: + +```json +{"baseRevision":0,"plan":{"schemaVersion":1,"revision":1,"nodes":[{"id":"result","binding":"echo","version":"1","args":{"value":"hello"}}]}} +``` + +Each frame is a complete self-contained DAG. Unclosed fragments and unresolved prerequisites never execute. The frame must advance the current revision by one; identical retransmission is idempotent. Committing a revision and reserving its nodes share one fenced CAS. Only unclaimed pending nodes can change or be removed. Claimed/prepared/running/completed/failed/uncertain node definitions and dependency bindings are immutable. Replaced pending nodes retain superseded tombstones and receive new incarnation/expansion charges. No revision rolls back effects. Stale attempts cannot commit; destination receipts and retained attempt records remain evidence. + +The producer and scheduler progress independently. With capacity greater than one, a validated prefix can execute while more frames arrive. At capacity one, effects wait until the stream releases its model slot. Old compiled callbacks cannot dispatch superseded incarnations; already claimed work drains, then the scheduler rebuilds from the latest persisted revision and reuses completed outputs. + +Planning seals only after a successful terminal provider result and EOF. Malformed/truncated fragments, interruption, cancellation or exhaustion retain committed work and an explicit interrupted state; a prefix is never reported as planning success. Permanently exhausted correction/attempt allowances fail the task with the original validation cause. Recovery uses a new bounded continuation request based on the current materialized revision and observations, without resampling historical plans. Sealed plans need no further planning call. `maxFrameBytes`, cumulative `maxTotalBytes`/`maxFrames`, output tokens, root counts, correction limits and original deadline bound planning. `maxLatencyMs` defaults to 30 seconds per planning call. Providers/connectors must honor their cancellation/timeout contract; the SDK cannot preempt physical remote work. + +## Verification + +The repository includes focused decision tests, actual fresh-process SIGKILL tests against MongoDB, packed ESM/CommonJS/public TypeScript consumers and an offline paired evaluation. Run `AGENTIUM_DURABLE_MONGO_TEST=1 npx vitest run packages/core/src/durable/__tests__/mongodb.integration.test.ts packages/harness/src/runtime/__tests__/execution-graph.mongodb.test.ts` against a disposable local backend. The graph suite covers dispatch/receipt crash windows, siblings, Agents, repeats and unsealed stream commits.

Root concurrency and lifetime limits span nested graphs, repeats, Agent tool batches and planning. An optional model planner generates validated catalog DAGs.

A program chooses exactly one of `plan` or `planner`; a node selects only a catalog binding ID/version and JSON arguments. An abbreviated plan is: + +```ts +{ schemaVersion: 1, revision: 1, nodes: [ + { id: "result", binding: "echo", version: "1", args: { value: "hello" } }, +] } +``` + +## Recovery and effect semantics + +The task pins manifest/catalog/program/binding identity, original input, policy/grants, budgets and absolute deadline. Plain programs, nested templates, limits and policy configuration are copied at construction. Opaque schemas/providers/Agent instances and callback implementations remain host-attested by version. Descriptor changes fail before resumed work. + +Materialized revisions and node incarnations have stable IDs. Node inputs, outputs and attempts carry digests and worker fences. Completion persists before successors. Completed nodes replay their outputs; interrupted running work restarts under a newer fence; failed/cancelled work remains terminal. Repeat guards and materializations are retained. Inspecting state neither claims ownership nor mutates a task. + +Agent nodes restart from node entry using request-bound complete recorded model responses and stable tool-call IDs. Approved tools are reauthorized before replay. Confirmed raw outputs/receipts are reused without a new dispatch attempt or duplicate logical tool charge. An interrupted model reservation remains conservatively charged; budgets and deadlines never replenish on recovery. Unsupported dynamic hooks, memory, handoffs, unbounded model outputs, caches, output transforms and non-JSON/opaque continuation fail preflight. + +An effect binds the node incarnation, call, binding/version and parsed arguments, plus policy/grants/identity. Append-only origin evidence selects the exact originating operation for reconciliation, even if two connectors share destination/version. Root admission occurs while the action is prepared, before remote dispatch is recorded as executing. Local admission failure stays known not dispatched. The permit spans dispatch and receipt settlement. Confirmed replay/reconciliation needs no fresh dispatch allowance. + +Acceptance followed by process death before receipt persistence requires confirmed reconciliation, proven absence/destination idempotency, or explicit `DurableRecoveryRequiredError`. Missing/transient evidence cannot justify unsafe redispatch. Fenced workers cannot settle current nodes, but physical late remote work may still finish and retain its destination receipt. **There is no exactly-once external-execution or remote-rollback guarantee.** + +## Scheduling and planning semantics + +One root slot covers an actual provider request/stream or controlled tool/function callback. Graph/repeat/Agent containers hold no slot while waiting for children, so capacity one completes without a parent-child deadlock. Nested controlled dispatch inside a leaf is rejected. Streams retain their slot until closure; already-owned cleanup can run after cancellation while preserving nesting/ownership guards. FIFO queue cancellation and deadline checks stop further admission. + +`maxExpandedNodes` counts unique materialized incarnations, including pending replacements. `maxWorkAttempts` counts fresh leaf dispatches. `maxPlanRevisions` counts revision admissions across all episodes. These monotonic counters supplement model/tool/token/deadline budgets and persist before dispatch. Removed nodes and interrupted/conservative reservations do not refund allowances. Snapshot/admission events expose queue, active work and exhaustion. Providers retain ownership of transport retries; a controlled invocation is one work attempt. + +The optional planner is tool-free and uses authorized harness model ports and shared budgets. System messages retain host instruction authority; catalog, input, retrieved/tool content and observations are source data. Validate complete proposals for identity, schemas, declared references, dependencies/cycles, bytes/nodes/cumulative depth/concurrency, revisions and supported effect policy. Record accepted/rejected proposals and causal diagnostics. Correction/fresh-call ownership is bounded across recovery; permanently exhausted invalid proposals fail with their cause. + +Streams accept newline-terminated, complete self-contained `{baseRevision, plan}` frames. Fragments, unapproved operations and unresolved prerequisites never execute. Revision commit and node claim serialize under fenced CAS. Only unclaimed pending work may change; claimed/prepared/running/completed/failed/uncertain definitions and relevant edges are immutable. Replacement retains tombstones and spends new incarnation allowance. Old callbacks cannot execute superseded work; edits imply no rollback. + +Producer and scheduler progress independently. A committed prefix can execute before the stream ends when capacity permits. Capacity one waits for the model slot without deadlock. Planning seals only after coherent terminal provider usage and EOF. Interrupted or malformed continuation retains accepted work and evidence but cannot report planning success. Recovery uses bounded continuation from the current revision; sealed records replay without another planning call. Byte/frame/latency/token/correction/depth/root/revision ceilings and the original deadline apply. + +## Verification + +All final gates passed on macOS arm64, Node `22.23.1`, npm `10.9.8`, Vitest `4.1.11`.

RED/GREEN and full/backend/packed gates cover the final source payload. + +## Matched offline measurement + +Four tasks ran under the same deterministic provider policy, tool implementations and resource ceilings in three modes.

The DAG modes used fewer decisions but more synthetic tokens in this fixture. Tokens use the local fallback estimator and do not represent vendor billing; one local run without network delay does not establish production speed or live-model planning quality. The [evaluation report](evaluation.md) records matched caps, scoring, original failures, actual source hashes and reproduction command. Spend was zero paid calls and zero external effects. + +## Compatibility, dependencies and remaining limits + +No dependency, lockfile or package-version change was made. The harness package adds `EXECUTION-GRAPHS.md` to its packed files. Public contracts are additive and opt-in; ordinary Agent/Workflow/HarnessRuntime behavior and existing checkpoints remain compatible under the passing suites. The existing generic workflow driver still advertises non-durable execution. JavaScript consumers can inspect explicit durable-store capabilities; in-memory execution remains `durable:false`, and `requireDurable:true` rejects it. + +Required capabilities are complete; no required piece is deferred. Deliberate supported-binding limits remain: stateless JSON recovery, explicit pure/effect declarations, versioned host executable implementations, bounded Agent outputs, and supported model continuation shapes. Providers/connectors must honor cooperative cancellation/timeouts. An SDK lease cannot preempt physical remote work. Storage uses one bounded task aggregate (Mongo default 2 MB), so retaining large histories can fail before further mutation; no recovery evidence is silently evicted. Production failover and live-provider evaluations require their own environment/authorization. + +## Changed-file map + +| Responsibility | Files | +| --- | --- | +| Public runtime, catalog and exports | [runtime](../../packages/harness/src/runtime/execution-graph.ts), [contracts](../../packages/harness/src/runtime/graph-contracts.ts), [harness exports](../../packages/harness/src/index.ts), [core exports](../../packages/core/src/index.ts) | +| Fenced journal, supervisor entry and origin/receipt ports | [journal](../../packages/core/src/workflow/durable-graph.ts), [supervisor](../../packages/core/src/durable/supervisor.ts), [recovery ports](../../packages/harness/src/runtime/graph-recovery.ts) | +| Root controller, Agent/Workflow/tool coverage | [controller](../../packages/core/src/agent/root-execution.ts), [Agent](../../packages/core/src/agent/agent.ts), [services](../../packages/core/src/agent/execution-services.ts), [ToolExecutor](../../packages/core/src/tools/tool-executor.ts), [StepRunner](../../packages/core/src/workflow/step-runner.ts) | +| Planner, validation and streamed revisions | [planner](../../packages/harness/src/runtime/execution-planner.ts), [proposal](../../packages/harness/src/runtime/execution-proposal.ts), [commit](../../packages/harness/src/runtime/plan-commit.ts), [stream parser](../../packages/harness/src/runtime/plan-stream.ts) | +| Retained model/tool/token accounting | [budget](../../packages/harness/src/runtime/budget.ts), [driver](../../packages/harness/src/runtime/driver.ts) | +| Recovery/crash/review/planning tests | [Mongo](../../packages/harness/src/runtime/__tests__/execution-graph.mongodb.test.ts), [fresh worker](../../packages/harness/src/runtime/__tests__/fixtures/graph-crash-worker.ts), [review regressions](../../packages/harness/src/runtime/__tests__/execution-graph.review.test.ts), [ports](../../packages/harness/src/runtime/__tests__/graph-recovery.test.ts), [planning integration](../../packages/harness/src/runtime/__tests__/execution-planning.integration.test.ts) | +| Public consumption and usage | [packed consumers](../../packages/harness/src/__tests__/package-consumption.test.ts), [packaged guide](../../packages/harness/EXECUTION-GRAPHS.md), [package metadata](../../packages/harness/package.json) | +| Design and evidence | [design](design.md), [completed plan](plan.md), [admission inventory](admission-inventory.md), [recovery inventory](recovery-inventory.md), [planner inventory](planner-inventory.md), [evaluation](evaluation.md), [gate manifest](evidence/gates.json), [original checkout audit](evidence/original-audit.json) | diff --git a/plans/execution-graphs-v2/admission-inventory.md b/plans/execution-graphs-v2/admission-inventory.md new file mode 100644 index 0000000..a412a1f --- /dev/null +++ b/plans/execution-graphs-v2/admission-inventory.md @@ -0,0 +1,107 @@ +# Root admission and expansion inventory + +Read-only investigation for attachment c0b3a451-5aab-487f-a502-612a9edd4778, 2026-10-13.

Define defaults and units in the public contract, not by an ambiguous “maxSteps.” + +**Concurrent work:** one actively owned leaf dispatch, consisting of one model request (including its entire provider stream lifetime), one controlled tool invocation, or one controlled function/effect invocation. Model operations include planner, correction, control, finishing, recall/summary models and ordinary Agent models. Cache reuse or recovery reuse of confirmed results requires no dispatch slot. Graph, Repeat, Parallel, Condition, Agent orchestration and a planner awaiting its own child model call hold no slot. + +Acquire a leaf slot immediately before actual controlled dispatch, after all preparation/schema/grant/approval decisions; release after the leaf operation settles. Admission and release must be paired with try/finally and idempotent release. For ToolExecutor, release before toModelOutput/result summarization, since those may make separate controlled model calls. For harness ordinary model calls, acquire **after prepare**, which may invoke control models. For streaming requests, retain the slot across yields until return/throw/provider completion, including an interrupted unfinished stream. + +A root limit such as `maxConcurrentWork` is a positive safe integer; omitted preserves existing unlimited aggregate behavior. Local graph maxConcurrency and ToolExecutor concurrency still narrow local admission; neither can widen the root limit. + +**Lifetime materialization:** `maxExpandedNodes` counts every committed logical node occurrence, including structural nodes, across all nested materialized episodes and repeat iterations. Reserve the whole known episode before its first effect. New plan revisions charge new or replaced pending node incarnations; unchanged nodes/recovered materializations do not charge again. Removed nodes remain in audit and do not refund expansion. A static graph declaration and its StepRunner execution must share one stable identity and must not be counted twice. Root serial/parallel/condition nodes also need stable occurrence identity if they can invoke graph work. + +**Lifetime work attempts:** `maxWorkAttempts` counts each admitted leaf dispatch attempt, including retried requests and bounded planner correction calls. Queue waits, schema/grant rejection, completed-result reuse and reconciliation inspection do not create a new execution attempt. Charge once when dispatch admission becomes committed, rather than when initially enqueued. Attempts are monotonic and never reset after recovery. + +**Lifetime revisions:** `maxPlanRevisions` counts accepted materialized plan/stream commit revisions, while invalid proposals consume ordinary model/token/work-attempt budgets. An optional separate invalid-proposal cap makes correction ownership explicit. A committed no-op revision should either be rejected or consume its revision allowance; it must not create unbounded audit. + +These limits supplement existing model/tool/token/cost/deadline/repeat/local-node budgets. All finite limits should support zero where meaningful (no expansion/work attempts/revisions), but concurrency zero should reject configuration rather than create an unresolvable queue. No missing usage becomes known zero. + +## Root propagation and deadlock prevention + +Expose a borrowed root admission controller on RunContext or ExecutionServices, with optional per-run construction for standalone core use. Every child context, Workflow, Repeat iteration, nested graph, planner and Agent-local ToolExecutor must carry the same controller. A root identity must survive recovery; a fresh child run ID must not create another ledger. + +The narrow effect interception point is ToolExecutor's actual execute boundary. This covers local Agent tools, root services.dispatch, workflow dispatchEffect and planner tool bindings without adding a second Agent scheduler. The harness root and control model paths handle provider slots. Standalone Agents must wrap their provider using the same controller if root limits are requested without ExecutionServices. + +Do **not** acquire a global slot for the whole graph node, whole Agent run, complete tool batch, model preparation, parent runOwned, or root planner. A limit of one would deadlock each when it waits for children. + +Trusted function/tool callbacks can themselves launch Agent/model/tool/Workflow work. Blind reentrant permits do not solve this: one parent permit could spawn a batch of ten children. A finite global controller must distinguish orchestration from leaf bindings. Recommended safe first contract: + +- Graph/Repeat/Agent are orchestration bindings and hold no slot. +- Controlled function/tool bindings are leaf operations; nested controlled dispatch from a leaf is detected (for example with AsyncLocalStorage) and rejected before child effects. +- Hosts that need orchestration callbacks must express the children as supported structural nodes or use an explicit SDK orchestration binding that holds no parent slot. +- Arbitrary host code/network IO outside controlled ports cannot be bounded by an SDK semaphore and must never be described as covered. + +This is a real supported-bindings constraint, not a reason to omit global limits. Document it and test explicit rejection instead of allowing a hang. + +## Admission, cancellation and observability + +Use a FIFO root queue for ready leaf operations; queue entries carry root/episode/node/logical operation/attempt/revision identity, kind and signal. Local graph eligibility is still checked before enqueueing. Queued operations require no permit and occupy no work-attempt counter. + +When a waiter aborts, remove it and its abort listener, reject once with a stable code and make no outbound call. Root deadline/cancellation stops all admission and wakes every waiter. An admitted operation that fails or throws releases once; a started uncooperative operation cannot have its resource slot released early merely because local abort arrived. Its eventual outcome remains evidence. Limit exhaustion is terminal for new admissions but preserves prior results and accounting. + +Emit bounded events for queued, admitted, released, rejected/cancelled and exhausted operations, including limit/unit and causal IDs. Snapshot exposes active permits, high-water mark, queued count, expanded nodes, work attempts, revisions and root deadline. Avoid raw credentials/arguments in ordinary telemetry. Event IDs must support diagnosed duplicate release without modifying counters twice. + +## Durable accounting and fencing + +Persist root configuration/hash, absolute deadline, cancellation state, expansion/revision records, lifetime attempt counters and permit records in the same bounded DurableTaskStore task aggregate as graph state/actions. Root graph identity cannot span multiple independent task aggregates under this store's documented single-task atomicity guarantee. + +Use guarded store.update with the active DurableFence to atomically reserve expansion or acquire attempt+permit before effects. Counter increments and lifecycle/audit changes must commit together. CAS mutate callbacks are synchronous and may be reevaluated; they cannot call providers/connectors or emit uncommitted external events. Persist event evidence in the same mutation or emit after success with committed revision. + +Record active permits by stable logical operation plus fresh attempt ID and owner fence. Reject stale-worker acquisition, release, node/output/plan commits. Lease/fence renewal is existing supervisor behavior. Definition/binding/input/version checks run before recovering admissions. Hydration must not replenish limits, attempts, reserved/unknown usage or reset deadlines. A caller cannot widen limits by supplying different resume configuration. + +Existing harness model budgets are synchronous, and a root ledger is currently recreated. Durable integration must persist an admission before actual dispatch and restore counters/reservations from durable state, or bypass this in-memory ledger through a durable adapter with the same semantics. A mere on-terminal snapshot loses charges after crashes. Existing supervisor reserve(tokens,costMicros) is conservatively monotonic; it cannot by itself persist model/tool/concurrency/expansion limits. + +**Lease expiry does not prove a remote operation stopped.** On recovery an orphan running permit becomes uncertain and retains evidence. Do not simply erase it and admit another effect while claiming a strict bound on physically concurrent remote work. Reconcile its effect with a destination guarantee: confirmed receipt, verified absent with no future application, or explicit unresolved state. Unknown charges remain charged. A model with no reconciliation may retain conservative unknown accounting and require an explicit host resolution policy. Define the implemented concurrency guarantee precisely as controlled SDK ownership/admission versus remote physical activity. + +Known stopped local work can release a local permit when the new owner establishes the applicable terminal/recovery state; mutations remain fenced. Confirmed persisted action receipts reuse results and free the corresponding prior permit without dispatch. Explicitly unresolved operations stop unsafe repetition. Cancellation does not delete permit/action audit or imply rollback. + +DurableActionLedger already binds action ID to connector version, destination, arguments, identity, policy revision and grant refs; identity reuse with different inputs rejects. Use its logical identity and input digest, not random call IDs or scope paths. Confirmed actions can be reused, unknown actions require reconciliation. The current supervisor rejects unknown actions before invoking its handler, so an adapter needs an explicit recovery/reconciliation entry path before normal handler execution rather than hiding reconciliation inside an unreachable callback. + +## Meaningful acceptance tests + +Write each new behavioral test failing before implementation. Suggested focused deterministic cases: + +1. Outer parallel graphs each contain three functions; both local caps exceed root maxConcurrentWork=2. Hold callbacks with deferred promises, measure the **aggregate** active callback count and high-water mark, and assert max=2 throughout. +2. Two concurrent Agent nodes each return a three-tool batch. Their local executors have concurrency=5. Aggregate started tools never exceeds root=2; both Agents finish without deadlock. +3. Nested Graph → Repeat → Graph → Agent at root=1 completes. Structural and Agent nodes hold zero permits; observer sees only leaf operations. +4. Concurrent ordinary/planner/control/finishing model calls plus tool effects share the same global slot ceiling. A streaming model retains one slot while a tool waits until stream closes. +5. Model prepare causes a controlled summary call at root=1; tool toModelOutput causes a model call at root=1. Both complete, proving no parent permit spans preparation/transformation. +6. Leaf callback attempts nested controlled work at root=1. Reject before nested effect and release parent once, without hanging or creating a bypass. +7. Cancel two queued waiters while one callback is running; queued outbound count remains zero, queue empties, all listeners are removed, running slot settles exactly once. +8. Reject/throw and late cancellation paths cannot leak or double-release permits; subsequent permitted independent work can run. +9. Repeat factory produces individually valid graphs beneath local maxNodes but total expansion exceeds root cap. Last episode fails **before any of its effects**, and prior outputs/counters remain. +10. Streaming commit replaces a pending node, removes another and preserves a completed node. Charged expansion counts both incarnations, does not refund deletion, and unchanged completed node reuses its original identity/output. +11. A correction model request consumes attempts/calls/tokens; recovery lookup and confirmed-effect reuse consume none. Distinct actual retries consume new attempt allowance. +12. Cross-root isolation: two separate roots each have an independent ceiling, while siblings of one root cannot construct a new ledger. + +Use the existing real Mongo crash-worker fixture for persistent-backend evidence, rather than presenting in-memory maps as process-crash durability. Existing tests launch fresh child processes and SIGKILL under `AGENTIUM_DURABLE_MONGO_TEST=1`, endpoint `AGENTIUM_DURABLE_MONGO_URI` or isolated localhost27319; inspect environment before running. + +Persistent cases: crash after expansion admission; crash with two siblings running; crash after action receipt before node completion; kill a planner during a streamed commit; recover in a fresh worker. Assert unchanged root counters/deadline/configuration, completed reuse, orphan uncertainty, absence of unsafe duplicate dispatch, stale release/commit denial, retained permit/attempt evidence, and bounded aggregate slots through recovery. Compare full persisted state, not just terminal text. An unavailable Mongo environment is a named verification gap and prevents claiming tested persistent crash recovery. + +## Coordinator decisions requiring implementation agreement + +The units above are recommended, not frozen public API.

Base `e9551e3690bdf274fc66f82222851fe9d06d8e97`. Work in the existing managed checkout on `agent/durable-execution-graphs`; preserve the original concurrent checkout. All four requested capabilities are required. No paid providers, push, main merge, publication or deployment. + +## Architecture + +Reuse Workflow's validated DAG and owned-patch joins, existing Agent loops, ToolExecutor, ExecutionServices, MongoDBDurableTaskStore, DurableTaskSupervisor, DurableActionLedger and run records. Add a portable, versioned execution proposal plus a trusted binding catalog, a root admission controller, a fenced graph journal and a harness graph recovery adapter. Do not extend arbitrary opaque callbacks into a durability promise. + +The graph adapter compiles validated catalog nodes into existing Workflow steps. Compilation closures coordinate durable node start/settle and dispatch through the existing controlled ports; they are orchestration and hold no global leaf slot. Tool bindings dispatch exactly once through ToolExecutor. Agent bindings run the existing Agent with journaled model decisions and intercepted local tools. Structural graph/repeat catalog bindings compose the same runner, share the controller and durable task aggregate, and persist their materializations and guard decisions. Ordinary existing Workflow and Agent entry points remain supported. + +## Root scheduling contract + +`RootExecutionLimits` has optional `maxConcurrentWork` (positive safe integer), `maxExpandedNodes`, `maxWorkAttempts`, `maxPlanRevisions` (nonnegative safe integers). Omission preserves previous unlimited aggregate behavior. One slot means one leaf provider request/stream or actual controlled tool/function invocation. Graphs, repeats, Agents, planner orchestration and preparation/transformation hold no slot. Local caps can narrow this ceiling. Leaf callbacks may not initiate nested controlled work: detect and reject it, rather than waiting while holding a parent permit or allowing hidden reentrant oversubscription. + +`RootExecutionController` supplies `expand(ids)`, `revision(id)`, `run(kind,id,execute,signal?)`, stream-lifetime acquisition, snapshots and events. Unique logical node incarnations are lifetime expansions; every actual leaf dispatch is a work attempt; every committed materialized revision is a plan revision. Removed nodes do not refund counters. Recovered completed work, materializations and recorded responses are reused without new dispatch attempts. Queue cancellation removes waiters; started work releases on settlement, including throws. Tools release before model-output transformation; models acquire after preparation. + +The same controller flows through RunOpts, RunContext and ExecutionServices to ToolExecutor and provider boundaries, including Agent-local tools. A persistence port atomically records admission/counters before effects and restores monotonic totals under the task fence. The concurrency claim covers controlled SDK dispatch ownership; lease fencing cannot stop an already sent remote request. Unknown remote effects remain unresolved until destination reconciliation, rather than being treated as stopped because a lease expired. + +An owned permit exposes `cleanup(execute)` for stream iterator finalization after cancellation. It preserves ownership, concurrent-callback and nested-dispatch checks, grants no new attempt, and releases only after closure settles. Effect dispatch reserves its permit while the action is still prepared and keeps it through receipt resolution and durable settlement. Local admission failures therefore cannot be confused with uncertain remote acceptance. + +## Durable graph journal + +Use a runtime-validated `agentium.graph.v1` extension in the existing bounded task aggregate. Bind definition ID/version/catalog descriptors, original JSON input, root limits, absolute deadline and executable versions to the task's immutable manifest/policy/grants identity. Persist materialized plans/revisions, raw proposals and causal observations, node input digests and lifecycle, attempt/fence ownership, completed outputs, repeat decisions, recorded model decisions, budget state, admission audit, cancellation and superseded evidence. Reject incompatible/corrupt records and changed bindings/inputs before resumed effects. + +`DurableGraphJournal` is constructed with the store, task key, active fence and admitted definition. It initializes/validates records; exposes fenced `mutate` and validated read-only `snapshot`; owns `node(id,binding,input,execute)`, `model(id,request,execute)`, `decision(id,compute)`, and action-ledger-backed `effect(input,connector,resolveResult)`. All persisted values are finite JSON. Node completion is saved before successors can run. Completed nodes return recorded outputs. Running nodes restart under a new fenced attempt; failed/cancelled nodes remain terminal; uncertain outcomes require reconciliation before a new fenced attempt. Structural decisions are reused after recovery. Terminal task state is not silently reset. + +Supported durable bindings: host-declared pure JSON tools/functions; controlled effects with a versioned DurableActionConnector and immutable receipt resolver; Agents restricted to approved tools plus recorded complete model responses; static graph/repeat orchestration using supported catalog children. Unsafe arbitrary tools, dynamic resolvers/handoffs, non-JSON results and effects without a declared safe recovery policy are rejected before node admission. Function/Agent implementation versions and argument/output schemas are host-owned, never executable code from a proposal. + +Construction snapshots all plain program/catalog policy data, including nested argument templates, limits, grants and budgets. Opaque schema/provider/Agent/callback implementations remain host-attested bindings. Catalog and manifest descriptor checks precede episode and tool admission. Sandbox environment values contribute only hashes to the descriptor; the SDK does not expose their values to the planner. + +Before ledger intent, append-only `effect.origin` evidence records the originating binding ID/version, logical node/tool call, arguments and catalog/definition/manifest identity. Recovery verifies its prepared hash/idempotency key and resolves that exact operation. Connector version plus destination alone is ambiguous and must never select a reconciler. + +An interrupted Agent restarts from node entry with the same recorded model responses at the same operation positions. Each cached response is request-digest checked and persisted before its tools become eligible. Logical effects use node incarnation + recorded call ID/position, bound to operation/version/input; attempts/fences are separate identities. Confirmed receipts are reused; unknown/executing actions reconcile first or return explicit recovery required. Interrupted model calls retain conservative charges; a new request consumes remaining budget. This is recovery with recorded decisions, not exact playback of arbitrary host behavior. + +The adapter retains full harness budget state before actual dispatch and after settlement. Hydration includes used/reserved calls/tokens, tool admission identities, protected finishing capacity and unknown usage. Crashed reservations become conservative charged unknown usage; allowances/deadlines never reset. Replayed tools still undergo authorization, while stable admission identities prevent duplicate budget charge. Root cancellation is persisted and polled with lease renewal. The supervisor needs an explicit reconciliation hook before its unknown-action guard; reconciliation cannot be hidden in an unreachable normal handler. + +Durability is advertised only by the graph recovery adapter after requiring durable atomic CAS/fence storage, admitted catalog/definition validation and the journaled execution ports. Existing workflowDriver stays non-durable and old checkpoint formats remain unchanged. Hosts own backend lifecycle, credentials, schema/implementation versioning, receipt retention, destination idempotency and reconciliation. No exactly-once external-execution claim. + +## Proposal, planner and streaming + +A strict JSON proposal contains a schema version, revision and nodes with unique ID, binding ID/version, argument template, control dependencies and data references; optional local concurrency/merge fields are bounded by host limits. No code or grant claims. A host-approved catalog validates supported operations, literal arguments, declared input/output reference paths, pure/effect recovery compatibility and nested binding depth. Resolve and validate concrete arguments again before effect intent; future data cannot be proven by arbitrary Zod refinements at proposal time. Use null-prototype/validated keys and reject unsafe paths. + +The optional planner makes tool-free authorized `ExecutionServices.model` or `streamModel` calls with host instructions and proposals/observations in data messages. Invalid proposals have bounded correction ownership and consume ordinary call/token/work budgets. Persist proposed and accepted plans and causal observations. Existing Agent loop remains available. + +Streaming uses bounded NDJSON commit frames, each carrying exact `baseRevision` and a complete self-contained candidate DAG. Only complete validated frames can commit. Pending/unprepared nodes may be added, removed or replaced; changed nodes receive new incarnation and expansion charge. Running, prepared, completed, failed or uncertain nodes and their relevant dependency/input bindings cannot change. Commit and node claim serialize under the same journal CAS. Completed effects and superseded pending definitions remain evidence; edits imply no rollback. Late stale commits/settlements fail the fence/generation check. + +A producer continues consuming the stream independently of the scheduler. The stream may occupy a model slot, so the parser never awaits effects needing that slot. At capacity one effects wait for stream closure, without deadlock. Malformed/truncated frames, interrupted streams, exhaustion and cancellation retain committed revisions and explicit partial planning evidence. Recovery executes persisted commits rather than resampling historical plans. Byte, frame, depth, node, correction and revision limits bound planning and expansion. + +Depth includes the inherited episode depth plus the dependency path level. A child episode starts one level below its owning node; repeat iterations keep that child nesting level. The journal retains episode depth and rejects mismatch on recovery. Static, model-generated and recovered proposals all receive the inherited depth, so dynamic planners cannot reset the bound. + +## Acceptance and verification + +Required observable cases: aggregate slots across nested graph/repeat and multiple Agent tool batches; cap-one completion; nested leaf rejection; cancellation/leak checks; lifetime expansion/revision exhaustion before effects; both function and Agent recovery; completed reuse; changed input/version rejection; stale worker commits denied; retained budgets/deadline/cancel; unknown-effect reconciliation or explicit unresolved outcome; safe pending-only streamed revisions with interrupted planning recovery; invalid proposals before effects; host authority and old callers. + +Run fresh SIGKILL worker tests against the existing supported Mongo backend on a disposable task-owned local instance. Crash before dispatch, after destination acceptance/before receipt, after receipt/before node completion, with siblings, during repeat decisions and streamed commits. In-memory decision tests supplement rather than replace process-crash evidence. Use existing unique receipt destination or an equally evidenced test-owned Mongo destination. No live paid/external business effects. + +Finish with build, all workspace source/test types, default and applicable integration suites, packed consumers, Biome, documented examples and metadata.

Independent whole-change review and refresh + +The independent reviewer inspected the tracked diff, new core/harness runtime modules, public contracts, related execution boundaries, tests and documentation against the originating four-capability request. It did not edit source or run the full build/default/Mongo/packed gates. Those gates remain coordinator evidence. + +The first pass found five deterministic defects. The coordinator and implementation experts corrected all five with failing regressions before their corrections. The independent reviewer then repeated its original local TSX reproductions against the corrected source and fresh core artifact. The verified source payload is now committed as `a9b0d1ba903294963fb7a97d438cd46028e8d80a`; source input hashes are in `final-source-state.json`. + +| Original finding | Correction | Independent refreshed observation | +| --- | --- | --- | +| P1: dynamic planner children reset depth; thirteen episodes ran with maxDepth eight | Persist inherited episode depth; include dependency levels; validate static/generated/recovered plans with inherited depth | Task fails after eight planner calls, zero effects, retained depths 1–8 | +| P1: borrowed plain configuration changed arguments and budgets after admission | Copy static/nested programs, limits, grants, budgets, planner settings and tool protections; recheck descriptors at boundaries | Mutating caller value to 999 and tool allowance to 50 still executes admitted value 1 under allowance 1 | +| P1: reconciliation picked the first matching destination/connector version | Persist append-only originating binding evidence; validate exact action/input/catalog/manifest/prepared/idempotency identity | One effect, one correct reconciler call, zero wrong reconciler calls; one origin record | +| P2: cancellation blocked iterator.return before provider finalizer | Explicit owned-permit cleanup bypasses only active-work gate; retain ALS and ownership guards | Finalizer runs once while permit active; active permits zero afterward, work attempts one | +| P2: root admission rejection became unknown external effect | Acquire before ledger enters dispatch; retain permit through receipt settlement; forward cancellation signal | Zero-attempt task fails with root_attempt_limit, connector calls zero, action remains prepared | + +The final reviewer verdict was: **no open material standards/correctness or originating-spec findings in the inspected whole change**. It also rechecked pending topology changes racing node claims, stale-owner settlement, completed and uncertain Agent response recovery, reauthorization before cached tool reuse, root lifetime accounting, configuration snapshots, cumulative depth and incomplete stream success gating. No additional actionable defect was found in those boundaries. + +This is source inspection plus five independent deterministic local reproductions, not a universal correctness proof. Host version attestation still governs opaque executable behavior. Fencing cannot physically stop an already-sent remote operation. The coordinator's `review-green.log` separately records 102 passing tests across the six review/root/recovery suites; `review-parent-red.log` and the retained root/proposal RED logs preserve original failures.

Scope: the optional model-generated tool-DAG planner and safe streamed revisions requested in the 2026-10-13 attachment. No source edits, installs, builds, tests, commits or paid model calls were performed for this inventory. + +## Existing hooks and relevant constraints + +| Hook | Current behavior | Consequence for the extension | +|---|---|---| +| `packages/core/src/agent/execution-services.ts:42` and `:48` | Host `model`/`streamModel` ports receive provider, messages, options and optional child context. | Planner calls should use these controlled ports, never invoke `provider.generate`/`provider.stream` directly under harness execution. | +| `packages/harness/src/runtime/driver.ts:880` | `prepare` checks active state, reserves a model call, chooses a granted host model role, narrows tools, projects context, applies model options and joins cancellation/deadlines. | A first implementation can use `services.model/streamModel` with an empty tool list. Controller-selected role semantics still apply. Do not promise a dedicated planner role unless adding a granted-role operation. | +| `packages/harness/src/runtime/driver.ts:1216` | Reserves projected input plus output token capacity before dispatch. | Correction and streamed-planning calls use the same root budget. An invalid proposal must still retain billed usage and model-call consumption. | +| `packages/harness/src/runtime/driver.ts:1384` and `:1415` | Controlled generation/streaming account usage, run middleware, settle reservations, track iterator lifetime, and require a terminal usage record. | Preserve these wrappers and cleanup. During streaming, a valid committed prefix can survive a later model-protocol failure, but no uncommitted bytes become executable. | +| `packages/harness/src/runtime/driver.ts:204` and `:1254` | `controlModel(role, messages)` is explicitly granted, tool-free and shared-budget; skips ordinary controllers, projection and middleware to avoid recursion. It rejects provider/tool continuation and non-stop/tool-call outputs. | Useful for nonstreaming planning if planner deliberately uses this harness-specific seam. There is no existing `streamControlModel`, so streaming must use the existing controlled streaming port or add a symmetric optional host operation. | +| `packages/core/src/models/types.ts:217` | `responseFormat` supports text, JSON and JSON Schema. `StreamChunk` at `:117` has text deltas and tool-call fragments. | Provider schema hints improve generation but cannot replace SDK validation. A data-only NDJSON commit protocol can use plain text deltas without executing tool calls. | +| `packages/core/src/agent/llm-loop.ts:566` | Agent structured-output parse errors only warn; output may fall back to raw text. | Do not treat ordinary Agent structured output as an executable-plan validation boundary. Dedicated proposal parsing must fail closed. Preserve the Agent loop for ordinary workloads. | +| `packages/core/src/tools/types.ts:35` | ToolDef includes parameter schema, executable closure, optional raw JSON Schema, approval, sandbox and result transformer. | Catalog descriptions must exclude executable closures. Model proposals name catalog IDs/versions; host registration alone provides executable bindings. Raw JSON Schema and model metadata are not approval or effect authority. | +| `packages/core/src/tools/schema.ts:17`, `:32` and `:36` | Existing Zod 3/4 structural boundary, parse and safe-parse helpers. | Reuse for proposals and concrete arguments; introduce no schema-library migration. | +| `packages/core/src/tools/json-schema.ts:11` | Zod conversion diagnoses runtime-only transforms/refinements. | Do not assert that a proposal's schema proves arbitrary future output references satisfy executable refinements. Validate resolved arguments at admission as well. | +| `packages/core/src/tools/tool-executor.ts:249`, `:278`, `:299`, `:360` | Runtime schema validation, protected argument snapshots, mandatory policy composition, approval and sandboxed/direct execution. | Planner execution must keep this boundary. Do not dispatch raw catalog closures outside it. | +| `packages/harness/src/runtime/driver.ts:796` | Harness policy checks grants then calls `budget.admitTool()` before host policy. | Calling this policy during speculative plan validation consumes budget. Separate pure host catalog/preflight checks from final execution-time policy. | +| `packages/core/src/workflow/step-runner.ts:203` | Every ordinary FunctionStep under harness is already an effect via `dispatchEffect`. | Wrapping `services.dispatch(toolCall)` in an ordinary FunctionStep charges/adjudicates both the wrapper and tool. Prefer an explicit binding-step kind or a single controlled binding execution boundary. | +| `packages/core/src/workflow/graph-runner.ts:99`, `:216` | Episode validates complete materialized graph then snapshots/freeze edges; scheduler is currently one-shot. | Reuse graph validation/state ownership, but safe streaming needs a committed versioned plan journal and admission against the current revision. Mutating the existing frozen node array is insufficient. | +| `packages/core/src/durable/types.ts:105` | Atomic bounded task updates, CAS and fences; extensions can hold serialized state. | Commit revisions and pending-node claims in the same fenced aggregate.

Pending revisions must not overwrite any prepared/executing/confirmed/unknown action or reinterpret its inputs. | +| `packages/core/src/durable/records.ts:105`, `:136` | Sequenced fenced events and immutable artifact references, bounded retention; blobs precede reference commit. | Use bounded events for revision/causal observations and artifacts for immutable raw/validated proposals. Recovery state must not depend solely on events that may be truncated. | +| `packages/harness/src/runtime/events.ts:76` | Harness event history is explicitly in-process and non-durable. | Observability events supplement persisted graph state; they cannot serve as recovery proof. | +| `packages/harness/src/testing.ts:121` | Existing verified-host eval target preserves grants/model settings and records tools with bounded coverage. | Evaluate planner/stream cases through the actual harness; add planner-specific revision/reference/admission metrics rather than inferring them from displayed text. | +| `packages/harness/src/drivers.ts:19`, `:111` | Existing workflow driver is non-durable and follows the unchanged Workflow API. | Add durable capabilities only through a verified adapter. Preserve the default driver and old checkpoint consumers. | + +## Recommended implementation order + +1. Establish durable graph/node/binding contracts and root scheduling/expansion admission. Freeze those interfaces before implementing planner code. +2. Add a host-approved executable binding catalog and versioned serializable proposal format. Implement nonstreamed planning, full proposal validation and bounded correction through controlled model calls. +3. Add a bounded text-stream parser producing candidate commit frames. Connect validated frames to the same durable revision commit and scheduler admission protocol. +4. Add persistent-backend process-crash tests for revision commits, pending edits, in-flight siblings and planner restart; run matched offline fixtures through the public harness/eval surfaces. + +The catalog, proposals and stream protocol can be additive. They should not create another ordinary Agent loop, retry owner, independent budget ledger or external-effect adapter stack. + +## Initial design options + +The initial alternatives below motivate the contract. The concrete coordinator-aligned interface in the final sections supersedes these illustrative names and discriminated reference syntax. + +```ts +type BindingReference = { id: string; version: string }; +type PlanValue = + | { kind: "literal"; value: DurableJSON } + | { kind: "input"; path: readonly string[] } + | { kind: "output"; nodeId: string; path: readonly string[] }; + +type ProposedNode = { + id: string; + binding: BindingReference; + arguments: Record; + dependsOn?: readonly string[]; +}; + +type ExecutionProposal = { + schemaVersion: 1; + baseRevision: number; + nodes: readonly ProposedNode[]; + observations: readonly string[]; // References to retained causal evidence. +}; + +interface ExecutableBinding { + readonly id: string; + readonly version: string; + readonly description: string; + readonly inputSchema: AgentiumSchema; + readonly outputSchema: AgentiumSchema; + readonly tool: ToolDef; // Host-only; never serialized or taken from proposal. + readonly durable: SupportedDurableBinding; + validateProposalArguments(template: Readonly>): void; +} + +type PlannerOptions = { + maxCorrections: number; + maxProposalBytes: number; + maxPlanDepth: number; + maxNodes: number; + maxRevisions: number; + maxStreamFragmentBytes: number; +}; +``` + +Use a strict discriminated reference object; never interpret `${...}`, JavaScript, shell strings, JSONPath functions, URLs to executable modules, arbitrary property access or string interpolation as code. Array segments should be explicit validated indexes if supported. For object paths, read only own properties and reject prototype/accessor traversal. Input paths are bounded to the immutable root/node input snapshot. Output refs refer to a producer's recorded validated output in the same scoped graph episode. + +The approved catalog should expose only execution-eligible bindings. It needs an immutable digest covering IDs/versions, serializable input/output contracts, effect metadata and durable adapter identity. A restored plan rejects a changed catalog/binding version before admission. Catalog registration verifies executable uniqueness and recovery safety once; speculative validation cannot widen tool/model grants, substitute implementations, or grant itself approval. + +Tool-DAG execution should use one real tool boundary per binding operation. A binding-step kind is preferable to wrapping `services.dispatch` inside FunctionStep, because the latter creates a separately budgeted effect. The concrete adapter must preserve original tool schema transforms, policy, approval, sandbox and output transformer or reject unsupported combinations. For durable execution, transformations/sandbox hooks that can themselves perform effects need coverage in the durable adapter contract; a ToolDef's `read` label alone does not prove replay safety. + +Catalog Agent bindings can delegate to the existing Agent while relying on the same durable Agent-effect protocol. They must not imply arbitrary Agent restart safety from safe function recovery. Unsupported Agent tools, delegation or captured resource effects must fail before admission. + +## Complete proposal validation and bounded correction + +Validate all executable structure before committing/admitting any node: + +- Strict versioned shape; bounded JSON bytes/depth/arrays/strings; positive bounded revision fields; valid Unicode identifiers; duplicate IDs, bindings and fields rejected. +- Every binding exists in the frozen host catalog at the requested version, has a supported durable mode when durable execution is selected, and passes pure effect-policy compatibility checks. +- Node count/depth/local concurrency/replanning/revision allowances fit host limits and remaining root expansion. The model cannot raise them. +- All control and data references resolve within the candidate revision or retained immutable prior nodes; automatic data dependencies join control dependencies for cycle validation. +- Literal arguments and root-input values undergo runtime schema checks. Future output references undergo template/path/producer validation using declared supported output paths or host `validateProposalArguments`; every node's resolved concrete arguments must later pass its executable schema before effect intent/admission. +- No reference may depend on missing/cancelled/failed/superseded output or target an unsupported accessor/prototype path. Refine incompatible declared paths before effects. Data-dependent predicates/refinements that cannot be proven before runtime remain admission checks, clearly documented. +- Owned state/output keys join under the existing explicit conflict policy; completion timing must not choose the winner. Output is validated and persisted before downstream references become ready. + +A model proposal is data. Host-authored instructions remain the system/developer prompt; task content, retrieved content, tool observations and correction errors stay quoted user/source data. Reject unexpected tool calls from the planning response. A model-supplied `instructions`, `code`, `grants`, provider or executable field is not accepted by the schema. + +Count at most `maxCorrections + 1` complete logical planning responses. The planner owns schema correction only; providers/harness retain their existing transport retry ownership. Retain each raw proposal, validation diagnostics, model identity/usage, parent revision and causal observation refs. On exhaustion return a machine-readable invalid-plan terminal, not an empty success. Do not erase invalid attempts or reset budgets when correcting or resuming. + +Persist accepted materialized plans before dispatch, not only the model request needed to regenerate them. A restart uses committed plans and observations rather than resampling old choices. Interrupted uncommitted proposals may be discarded/replanned under the retained planning counters and original deadlines; expose this distinction from deterministic replay. + +## Safe streamed commit protocol + +Use complete bounded NDJSON records in text chunks. No raw delta or incomplete JSON record is executable. The parser caps individual fragment/record bytes and total proposal bytes, rejects unexpected tool/reasoning records as plan data, and emits strict records such as: + +```ts +type StreamedPlanRecord = + | { type: "commit"; proposal: ExecutionProposal; commitId: string } + | { type: "finish"; revision: number }; +``` + +Each commit supplies a complete replacement of the current executable topology, including immutable running/completed nodes, rather than relying on arbitrary in-place patches. A first commit can be a self-contained prefix: all its references/prerequisites resolve in the committed prefix. A future missing node cannot act as a placeholder for runnable work. Nodes depending on uncommitted future work stay in model/parser staging and cannot dispatch. + +Commit protocol: + +1. Parse/validate a complete frame and its proposed full topology. Resolve frozen catalog, static input references and immutable prior outputs. Compute canonical proposal/binding/input digests. +2. Atomically, under the current root lease fence and exact base revision, re-check phases/action intents, reject protected-node changes, consume total expansion/revision allowance, and persist the new materialized plan, causal observations and commit decision. +3. Notify/wake scheduler only after that write succeeds. Scheduler claims readiness and freezes a node's concrete inputs against the currently committed revision under the same atomic protocol. +4. A duplicate `commitId` with the same canonical proposal returns the recorded decision. The same ID with changed bytes conflicts. An obsolete base revision conflicts; do not reinterpret the proposal silently against a later revision. + +Allowed edits concern **pending and unprepared** work: add nodes, change their arguments/binding/dependencies, or remove them, provided all remaining dependencies and refs still validate. A node whose effect intent is already prepared is protected even if its display phase says pending. Running/completed/uncertain/failed/cancelled nodes and their causal inputs/output/effect evidence are immutable in a streamed revision. Editing dependencies of a completed node must also be rejected; it would rewrite the explanation of work already done. + +For an edited pending logical node, increment a persisted incarnation/generation, revoke superseded local admission tokens and never reuse the old effect identity for different inputs. An implementation may require a new logical node ID instead of silently changing the operation; either way retain prior candidate/commit/tombstone evidence and charge cumulative expansion. Deleting and re-adding work must not refund lifetime expansion. Immutable output references remain accessible even if topology rendering hides a retired pending declaration. + +Reject running/completed mutations for this feature. This is a supported safe streamed protocol; an explicit future cancellation/reconciliation protocol may permit broader replacement, but an abort signal does not prove the remote effect was rolled back. Late results/effect acceptances from superseded or fenced-out attempts are retained by durable adapter evidence and cannot overwrite current node state. A lease fence protects local commits, not an already-sent remote request. + +Frame commits and ready-node claims must serialize through the authoritative store. A preflight read followed by an unfenced mutation races with dispatch. Similarly, writing a journal event separately from topology without a recoverable commit marker can acknowledge a plan that never committed. + +## Global limits and stream lifecycle + +- A stream model call occupies the root's physical model-work slot until its iterator settles. It uses normal root model/token/deadline reservations. +- Graph/repeat/planner coordinators do not hold worker slots while awaiting children. Concrete controlled function/tool/model operations hold slots. Root allowance remains shared across nested graphs, Agent tool batches and planning. +- If root concurrency is one, consuming/committing the model stream must continue without awaiting an effect's completion; effects wait for the model slot to release. Otherwise "await commit, then await node, then read next model fragment" can deadlock. Graph execution and stream parsing need distinct progress channels. +- Charge each committed new incarnation/node expansion and every actual execution attempt according to the root contract. A failed correction/plan fragment consumes planning/model allowance as specified; it cannot create an unbounded new stream outside the root limits. +- On malformed fragments, interrupted stream, usage-protocol failure or budget exhaustion, retain already committed revisions and completed effects. Stop new admission, mark planning failure/partial terminal, drain already-started work, preserve late evidence and explicitly expose unresolved nodes. Do not pretend the prefix is a successful complete task. +- On cancellation persist root cancellation first, close the iterator, stop admissions and drain owned work. Recovery does not restore cancelled planning as a fresh run. Durable counters/deadlines/cancel state must survive attempts. +- A stream ending after a valid commit but without an explicit plan `finish` is interrupted planning. A plan `finish` alone is insufficient until the controlled model stream also settles its terminal protocol/accounting. Keep the final committed revision; do not silently discard completed work. + +## Required tests, not executed by this inventory + +Write observable failing tests before implementing the behavior: + +1. Valid chain/fanout/cross-dependency proposal uses one real tool admission per binding, correct causal output refs, deterministic joins and ordinary grants/approval enforcement. +2. Duplicate/malformed Unicode IDs, missing binding/version, code/grant fields, cycles, absent producer/path, deep/oversized JSON, incompatible literal args and unsupported durable effects fail before any unauthorized dispatch. +3. One malformed proposal then corrected proposal retains both records and shared model/token consumption; correction cap returns an explicit invalid-plan result. +4. An observation containing "ignore host policy" remains source data; a proposed forbidden binding fails even when the model labels it read-only. +5. Fragments split across every byte boundary emit zero executable work until a complete validated commit. A complete safe prefix may dispatch while a later record is still arriving. +6. Pending add/change/remove succeeds; changing running/completed/uncertain or action-prepared nodes fails. Editing a pending node racing with claim yields exactly one fenced winner, preserves old evidence and prevents stale publication. +7. Same commit ID/revision/bytes is idempotent; same ID/different bytes and obsolete base revision conflict. Removing prerequisites or introducing a future unresolved ref/cycle fails atomically. +8. Plan-generation/token/revision/node-expansion exhaustion stops new work without refunding consumed lifetime counters. Nested graph + Agent tool batches + streamed planner never exceed measured root active work. +9. Root concurrency one completes without parent/stream deadlock; cancelling queued work releases permits, while active work holds its permit until actual settlement. +10. Malformed later frame, missing stream finish, model usage-protocol failure and cancellation preserve committed effects/late evidence but produce a partial/failure terminal. +11. Fresh-process persistent-backend crashes before/after plan commit, during pending edits, during sibling effects and between repeat/replanning episodes restore the last authoritative revision, completed nodes and counters. Mocks cannot prove this. +12. Existing Agent/Workflow fixtures, ESM/CJS and TS/CTS packed consumers retain default behavior; new contracts are available through supported public exports. + +## Feasible evaluation contract + +Extend the existing public `scripts/compare-execution-graphs.ts` comparison with three paired arms: existing Agent loop, complete-proposal planner, streamed-prefix planner. Use task-keyed deterministic providers first, identical executable tools, input/output schemas, grants, root model/token/tool/expansion/concurrency budgets and isolated storage. Keep held-out expected outputs out of model-visible prompts. Fix cases and number of runs before execution. + +Cases should include ordinary chains/fanout/cross-dependencies, useful pending correction, malformed/forbidden proposal, stream interruption, superseded pending work, budget exhaustion and ambiguous effect reconciliation. Match the model fixture and resource ceilings; report each arm's actual consumed calls/tokens rather than equalizing consumption after the fact. Correctness must mean completed validated outputs; partial prefixes stay in the denominator as failures/partial outcomes. + +Record task correctness, dependency violations, forbidden-binding proposals versus actual unsafe dispatches, unresolved effects, stale-commit attempts accepted/rejected, model calls/tokens, tool/attempt/expansion counts, peak aggregate work, wall time and unknown usage. Preserve infrastructure failures, cancellation and skips separately. Offline fixtures show protocol correctness only. Their timing with zero provider delay cannot establish production latency, task quality or billed-cost improvement. Paid/live provider evaluation is separately unauthorized; do not perform it. + +## Compatibility and material limitations to document + +The planner remains optional, and existing complete GraphStep/RepeatStep/Agent paths preserve behavior. A new binding/planning step variant is additive but exhaustive external switches may need updates. Keep v2 top-level checkpoint formats readable; durable graph recovery uses a separate versioned adapter/state contract rather than relabeling those checkpoints durable. Host-owned credentials/storage/connectors remain outside serializable plans. + +Supported streaming means validated self-contained commit frames and pending edits under fences, not unrestricted live code mutation. Future-output argument refinement remains a concrete admission check. Graph durability must explicitly cover Agent effects or reject unsafe Agent bindings before dispatch; safe function-only tests cannot establish general Agent recovery. Local fencing and retained evidence do not guarantee exactly-once external execution. These are semantic boundaries, not reasons to omit the required capabilities. + +## Concrete API contract aligned with the coordinator + +This section is design-only while foundation tasks 1–3 are implemented. No planner/stream source implementation should start before their working gate. Coordinator owns `packages/harness/src/runtime/graph-contracts.ts` (GraphBinding), runner, journal CAS and budget/admission integration; the planner expert can own new proposal validation, model generation and bounded NDJSON decoding modules/tests without shared-file edits. Keep these new modules in harness alongside that catalog to avoid a core-to-harness package dependency. + +```ts +// Parent-owned executable catalog. parseInput/parseOutput are host JSON validators; +// names can align with the foundation module without changing these semantics. +type GraphBinding = + | { + id: string; version: string; kind: "tool"; tool: ToolDef; + parseInput(value: unknown): DurableJSON; + parseOutput(value: unknown): DurableJSON; + recovery: "pure" | { + connector: DurableActionConnector; + resolveResult(resultRef: string): Promise; + }; + } + | { + id: string; version: string; kind: "agent"; agent: Agent; + tools: readonly string[]; + parseInput(value: unknown): DurableJSON; + parseOutput(value: unknown): DurableJSON; + } + | { + id: string; version: string; kind: "graph"; program: ExecutionPlan; + parseInput(value: unknown): DurableJSON; + parseOutput(value: unknown): DurableJSON; + } + | { + id: string; version: string; kind: "repeat"; program: ExecutionPlan; + maxIterations: number; + while(state: DurableJSON, completedIterations: number): boolean; + parseInput(value: unknown): DurableJSON; + parseOutput(value: unknown): DurableJSON; + }; + +// JSON templates are literal JSON except reserved exclusive output-ref objects. +type GraphOutputReference = { $ref: { node: string; path: readonly string[] } }; +type ExecutionPlanNode = { + id: string; + binding: string; + version: string; + args: Record; + dependsOn?: readonly string[]; + inputsFrom?: readonly string[]; +}; +type ExecutionPlan = { + schemaVersion: 1; + revision: number; + nodes: readonly ExecutionPlanNode[]; + maxConcurrency?: number; + merge?: "error" | "declaration_order"; +}; +type PlanValidationLimits = { + maxBytes: number; + maxNodes: number; + maxDepth: number; + maxConcurrency: number; + durable: boolean; +}; +type PlanReferenceRequirement = { + consumer: string; + producer: string; + outputPath: readonly string[]; + argumentPath: readonly string[]; +}; +type ValidatedExecutionPlan = { + plan: ExecutionPlan; + order: readonly string[]; + referenceRequirements: readonly PlanReferenceRequirement[]; + digest: string; + catalogDigest: string; +}; +function validateExecutionPlan( + value: unknown, + catalog: readonly GraphBinding[], + limits: PlanValidationLimits, +): ValidatedExecutionPlan; +function resolvePlanArguments( + node: ExecutionPlanNode, + outputs: ReadonlyMap, +): Record; + +type PlanCommitFrame = { baseRevision: number; plan: ExecutionPlan }; +type ValidatedPlanCommitFrame = { + baseRevision: number; + validated: ValidatedExecutionPlan; +}; +type PlanStreamLimits = { + maxFrameBytes: number; + maxTotalBytes: number; + maxFrames: number; +}; +// Decoder accepts text chunks; model adapter separately rejects tool-call chunks. +function decodePlanCommitFrames( + source: AsyncIterable, + limits: PlanStreamLimits, + signal?: AbortSignal, +): AsyncGenerator; +``` + +`args` is a JSON object whose nested ordinary values may contain an exclusive `{$ref:{node,path}}` object. A reference object may not have additional fields; malformed `$ref` markers fail instead of falling back to a literal. This reserves `$ref` within planner argument objects; if a workload requires literal `$ref` payloads, it needs an explicit separately-versioned escaping convention. Do not add ambiguous string interpolation. JSON numeric path segments can be permitted only when canonical array-index syntax is validated; other path segments use own-data-property traversal and reject `__proto__`, `prototype` and `constructor`. + +References infer mandatory data/scheduling edges in addition to declared `inputsFrom`/`dependsOn`. Declared `inputsFrom` must also resolve and can supply inherited state according to the parent runner contract. Any producer needed by an argument is not optional, even if the model omits it from declared edge arrays. The pure validator returns requirements without creating phases, allocating incarnations, contacting providers, charging budgets, evaluating a repeat guard, calling parseOutput on absent future values, or invoking host authorization. + +The version pins the implementation/schema/predicate contract. Durable catalog construction must reject duplicate IDs, invalid versions, unsafe bindings, unsupported Agent-local tool access and recursive static programs. Freeze trusted catalog references or copy their descriptors at registration; plain readonly TypeScript properties do not prevent runtime replacement. An Agent's `tools` getter (`packages/core/src/agent/agent.ts:96`) and harness-tools merge (`:499`) mean the declared allowlist must be enforced at dispatch, not checked only once when registering the Agent. Host version discipline remains necessary for opaque closure behavior. + +`parseInput` may normalize validated concrete data; persist the normalized result and its digest before any effect identity is bound. During structural proposal validation, call it only when args have no unresolved refs. For referenced arguments, the binding needs a pure template validator or explicit declared reference-path contract if the SDK promises preflight type compatibility. Otherwise the documented guarantee is structural reference validation plus full concrete input validation before dispatch, not proof that every possible future value passes custom predicates. `parseOutput` validates every effect/Agent result before persistence and successor readiness. + +Planning interface: + +```ts +type PlannerObservation = { + id: string; + kind: "input" | "node" | "effect" | "validation"; + data: DurableJSON; +}; +type PlannerProposalRecord = { + id: string; + baseRevision: number; + source: "model" | "stream"; + raw: string; + observations: readonly string[]; + status: "proposed" | "validated" | "rejected" | "interrupted"; + planDigest?: string; + diagnostics?: readonly { code: string; path: readonly string[]; message: string }[]; +}; +interface ExecutionPlannerConfig { + provider: ModelProvider; + catalog: readonly GraphBinding[]; + validation: PlanValidationLimits; + maxCorrections: number; + maxOutputTokens: number; + stream: PlanStreamLimits; + hostInstructions: string; + record(record: PlannerProposalRecord): Promise; +} +interface PlannerRequest { + services: ExecutionServices; + ctx: RunContext; + baseRevision: number; + input: DurableJSON; + observations: readonly PlannerObservation[]; + currentPlan?: ExecutionPlan; +} +interface ExecutionPlanner { + plan(request: PlannerRequest): Promise; + stream(request: PlannerRequest): AsyncGenerator; +} +function createExecutionPlanner(config: ExecutionPlannerConfig): ExecutionPlanner; +``` + +Planner `record` is required so proposed/invalid/corrected choices are available for diagnosis; the parent binds it to its bounded journal/records sink in durable mode. Journal `record` failure prevents plan dispatch. Model usage stays in the controlled model port rather than a second ledger. `plan()` requires a complete stop response without executable tool calls, uses at most `maxCorrections + 1` controlled calls, and returns a validated plan for the parent to commit. Parsing/correction failures throw a typed machine-readable error. `stream()` generates validated candidate frames, never calls catalog tools or commits phases itself. The parent owns authoritative commit, decision evidence and scheduler coordination. + +The stream adapter consumes only text chunks as NDJSON proposal bytes. Provider thinking/public messages remain non-executable observations; any tool-call fragment fails planning. In this frames-only protocol, successful provider completion/EOF seals planning. Buffered non-whitespace at EOF is a malformed trailing frame. Missing terminal provider accounting, truncation, stream error or cancellation is interrupted planning even after earlier frames were valid. Parent observes successful seal separately from the existence of an accepted frame; a nonempty prefix alone is not complete task success. Nonstream correction is bounded; malformed streamed planning may fail explicitly after retaining its prefix without a second correction stream. + +## Frozen revision and pending-edit rules + +An uncommitted episode has revision `0`; first plan revision is `1`. A frame for base `N` requires `plan.revision === N + 1`. Accepted exact retransmission of an already-recorded revision/digest returns the previous decision. Conflicting bytes at the same revision or an obsolete unrelated base fail. Parent journal CAS owns these rules; pure validation alone cannot detect a concurrent claim. + +The candidate is a full plan, with identical canonical definitions for all existing protected nodes. Parent must compare binding/version/args/control/data edges, not only IDs. "Protected" includes any node with prepared effect intent, allocated irreversible ownership or a running/completed/failed/cancelled/uncertain record. The allowed phase is pending and unprepared. Changed pending nodes receive a new persisted incarnation; removed nodes are tombstoned, not erased from evidence, and expansion is never refunded. References to removed pending nodes fail. Existing immutable producer outputs/effects remain retained; revisions cannot imply rollback. + +Candidate validation must precede its atomic commit, and the commit must revalidate protection against current authoritative node state. Only after commit acknowledgement may the scheduler claim nodes from that revision. Before dispatch, claim checks revision/generation, concrete input digest and catalog version; stale/superseded attempts may retain evidence but cannot publish into current state. Parent does not hold a root leaf slot while waiting for these orchestration actions. + +Coordinator implementation agreement: the commit reserves all candidate node identities as pending journal records before scheduling. Identity is scope/node ID/incarnation, and replaced or removed pending records become superseded tombstones. `journal.node` performs the claim CAS; an active same-fence duplicate claim rejects. The runner executes an existing Workflow for the observed committed topology, checks incarnation at claim, drains already-started work, then rebuilds from the latest plan with completed outputs cached. Superseded pending callbacks cannot execute. The stream parser progresses independently of graph completion, including at root concurrency one. + +## Reusable Mongo process-fixture layout + +Existing reliable hooks: + +- `packages/core/src/durable/__tests__/fixtures/crash-worker.ts:6` accepts explicit URI/database/task/phase. It initializes a fresh Mongo store and supervisor; `:29` blocks after intent preparation and `:39` blocks after a real Mongo effect but before returning its receipt. IPC indicates the reached barrier before SIGKILL. +- `packages/core/src/durable/__tests__/mongodb.integration.test.ts:30` launches independent `fork` workers with `--import tsx`, captures stderr and a 15-second timeout, waits for IPC and exits. `:61` kills workers; `:67` waits past lease expiry. `:85` tests two-process arbitration and a stale fence. +- `packages/harness/src/watch/__tests__/fixtures/mongo-watch.ts:20` builds the same real store, unique Mongo document effect connector and test services; `:28` provides reusable named barriers. The connector requires acknowledged durable destination writes, not a vi.fn result. +- `packages/harness/src/watch/__tests__/watch-mongodb.integration.test.ts:10` follows the same IPC/SIGKILL/lease-expiry pattern. Both suites use `AGENTIUM_DURABLE_MONGO_TEST=1`, explicit `AGENTIUM_DURABLE_MONGO_URI`, isolated generated database names and task-owned cleanup. + +Recommended new files owned by the process/eval worker: + +```text +packages/harness/src/__tests__/fixtures/durable-graph-fixture.ts +packages/harness/src/__tests__/fixtures/durable-graph-worker.ts +packages/harness/src/__tests__/durable-graphs-mongodb.integration.test.ts +scripts/compare-durable-execution-plans.ts +``` + +`durable-graph-fixture.ts` should construct the parent adapter, pinned catalog, deterministic offline model, fresh store/records and real Mongo effect destination. `durable-graph-worker.ts` receives only explicit test endpoint/database/task/scenario/phase and IPC commands. Reopen the same task in a **second fresh process** for recovery, rather than proving only that the Vitest parent can reconstruct a runner. Maintain destinations/counts/dispatch audit/model audit in the isolated database so all assertions survive process death. + +Barrier phases should cover `plan.before_commit`, `plan.after_commit`, `node.claimed_before_dispatch`, `effect.accepted_before_receipt`, `effect.receipt_before_node_done`, `sibling.one_done_one_running`, `repeat.guard_committed`, `repeat.next_episode_committed`, `stream.prefix_committed`, `stream.pending_revision_committed`, and `agent.model_recorded_before_tool`. Wrapper-based phase hooks should be test-owned: observe acknowledgements from store/connector operations, send IPC, then await forever; do not add production crash knobs solely for testing. + +Use a noncrashing sibling fixture to prove its completed output is reused. Use the real document connector's read/reconciliation to resolve a killed accepted effect without increasing destination count. After a killed prepared effect, admission may dispatch safely under the same operation intent. After receipt but before node completion, receipt resolver completes the node without redelivery. Record original absolute deadline and budget/admission snapshots in the task, verify they persist, and exhaust only remaining allowance on recovery. Simultaneous recovery workers should yield one fence owner and reject an old fence's node/plan commit. + +The test worker's stream provider can emit one closed safe frame, block on IPC while a sibling runs, emit a pending-only replacement and block after its persisted acknowledgement, then be killed. Recovery verifies the second committed revision, obsolete pending incarnation tombstone and completed outputs. A separate invalid replacement case attempts to edit the running sibling and asserts revision unchanged plus rejection evidence. Task corruption/binding-version mismatch must fail before any destination insertion. + +## Focused local test plan for planner ownership + +Planner expert-owned source/test files, after the foundation gate: + +```text +packages/harness/src/runtime/execution-proposal.ts +packages/harness/src/runtime/execution-planner.ts +packages/harness/src/runtime/plan-stream.ts +packages/harness/src/runtime/__tests__/execution-proposal.test.ts +packages/harness/src/runtime/__tests__/execution-planner.test.ts +packages/harness/src/runtime/__tests__/plan-stream.test.ts +``` + +Parent supplies/imports the trusted GraphBinding shape and owns index exports and runner integration. Tests should pin public observable contracts before implementation: complete proposal reference/dependency validation without invoking catalog execute/policy/guard; byte/depth/node/concurrency bounds; exact safe own-property reference resolution; pure literal and concrete input validation; one controlled model call then one bounded correction; forbidden tool/code/grant proposals; proposal record retention/fail-closed sink; provider cancellation/accounting behavior; every text-fragment split point; valid self-contained prefix emission; malformed later frame preserving prior output; incomplete tail; frame and total byte bounds; duplicate revision and monotonic candidate rules. Real phase/edit CAS and persistent recovery belong in parent/process integration tests. + +Stop after this contract and fixture plan until the coordinator signals tasks 1–3 working. These sections are a proposed freeze, not evidence of implemented capability. + +## Durability-foundation implementation status + +The coordinator subsequently authorized the pure catalog/proposal validator and journal commit helper as prerequisites for safe durable admission. Model planning and streamed model integration remain behind the foundation gate. + +Implemented owned modules: + +- `packages/harness/src/runtime/execution-proposal.ts` exports `validateExecutionPlan(value, catalog, limits)`, `resolvePlanArguments(node, outputs, maxDepth = 64)`, `graphCatalogDescriptor(catalog, limits)`, `graphCatalogDigest(catalog, limits)` and `ExecutionPlanValidationError`. +- `packages/harness/src/runtime/plan-commit.ts` exports `MaterializedExecutionPlan`, `commitExecutionPlan(journal, root, scope, frame)` and `readExecutionPlan(journal, scope)`. + +Validation rejects malformed or executable data, undeclared output references, missing/cyclic dependencies, unsafe property paths, unsupported durable tool recovery, and unsupported durable Agent configuration before execution. Referenced arguments require exact host declarations and template approval; resolved arguments are subsequently parsed by the parent runtime at admission. Nested graph/repeat programs share inherited depth checks; repeat guards do not execute during preflight. Durable tool cache and `toModelOutput` options fail admission until an explicit recorded policy exists. Ordinary `durable: false` validation retains support for these options. Catalog JSON schemas use only the trusted converter's serialized JSON representation, removing Zod4's nonenumerable `~standard` runtime annotation before strict finite-JSON validation. Untrusted proposal validation remains strict. + +Commit preflight uses authoritative journal time and phases before reserving lifetime counters, then repeats those checks in the commit CAS. It atomically retains a revision at `${scope}/revision/${revision}`, updates `plan:${scope}`, reserves pending node records and supersedes obsolete unclaimed incarnations. Stable node keys are `node:${durableDigest([scope, node.id, revision, nodeDefinition])}`; their scope, node ID and originating revision are retained in metadata. Identical retained revisions return their original materialization without regressing the current pointer or charging again. Losing races and failed reservations conservatively consume admission allowance. Protected operations and their causal definitions remain immutable, including removal or a later change to merge semantics. Declared ordering cannot reorder protected writers. + +Local verification on 2026-10-13: + +- Proposal tests: 43 passed, covering the initial RED implementation, targeted RED cases for premature catalog callbacks, Agent approval/configuration, dependency depth, duplicate executable names, Zod4 descriptors and unrecorded durable tool policies. +- Commit tests: 17 passed, covering retained revisions, pending replacement/removal, prepared/completed/uncertain/cancelled immutability, original deadlines and cancellation, bounded reservations, ownership restart, snapshot corruption, a real in-process claim-versus-commit race and competing revision CAS. +- Parent static adapter tests: 4 passed in the combined focused run. Total: 64 tests across three files. +- Biome checked and formatted all four owned source/test files successfully; harness `tsc --noEmit` succeeded. + +Evidence logs: `/tmp/agentium-planner-foundation-green.log`, `/tmp/agentium-planner-foundation-biome.log`, `/tmp/agentium-planner-foundation-tsc.log`; targeted RED logs include `/tmp/agentium-execution-proposal-zod4-red.log` and `/tmp/agentium-execution-proposal-tool-policy-red.log`. These checks prove local contracts and adapter integration. The commit fixture uses an in-memory task store; it is not evidence of persistent-backend process-death recovery. The coordinator owns those separate Mongo process checks, package exports and the runtime adapter. No optional planner or stream implementation, source commit, backend launch or paid model call has been performed by this worker. + +## Planner implementation after the foundation gate + +The coordinator confirmed foundation adapter, global capacity, budget restoration and fresh Mongo worker recovery checks before authorizing optional planning implementation. Implemented modules now include `packages/harness/src/runtime/execution-planner.ts` and `packages/harness/src/runtime/plan-stream.ts`; the earlier inventory's read-only status describes its initial phase. + +Final integration APIs are: + +```ts +interface ExecutionPlanGenerationOptions { + program: ExecutionGraphProgram; + scope: string; + input: DurableJSON; + catalog: readonly GraphBinding[]; + limits: PlanValidationLimits; + services: HarnessExecutionServices; + journal: DurableGraphJournal; + root: RootExecutionController; + signal?: AbortSignal; + depth?: number; +} +generateExecutionPlan(options): Promise; +streamExecutionPlans(options, onCommit: (plan: MaterializedExecutionPlan) => void): Promise; +decodePlanCommitFrames(source, limits, signal?, onFrame?): AsyncGenerator; +``` + +`onCommit` is a synchronous notification to wake the independent scheduler. It does not wait for graph nodes or effects. `onFrame` is an optional async pre-parse evidence observer used by the planner; standalone decoding needs no observer. The decoder emits only newline-closed protocol frames, supports arbitrary fragments and CRLF, bounds UTF8 bytes and frames, retains valid prefix emission before a malformed later frame, and races a suspended `next()` against cancellation. It requests iterator cleanup without waiting indefinitely for an uncooperative source after abort. + +Planning metadata at `planning:${scope}` pins configuration, input, provider, catalog, inherited depth and mode. It retains lifetime attempts/corrections and stream bytes/frame counts across owners. Complete calls and stream lifetimes use `journal.model` IDs `${scope}/planner/model/${index}` around the existing controlled `services.model` / `services.streamModel` operations. Requests always supply `tools: []`, bounded output tokens, a 30-second default call latency, the original absolute deadline, and combined caller/services/root cancellation. The optional `PlanStreamLimits.maxLatencyMs` changes that host-pinned latency. Neither models nor proposals construct callbacks, widen grants, invoke policy preflight or dispatch catalog tools. + +The controlled prompt puts fixed host instructions and protocol requirements in the system message. Input, catalog descriptors, current retained topology, operation status/output-digest observations and validation diagnostics remain user source data. Proposed, validated and rejected frames retain bounded raw evidence, source/model identity, input digest, plan digest and base-revision causality. Normalized model responses and stream terminal usage are retained without opaque provider objects or credentials. + +Corrections apply only to invalid complete proposals. A failed commit admission interrupts immediately instead of spending correction calls. A transport failure, malformed stream or provider truncation with remaining allowance raises `DurableRecoveryRequiredError` while retaining committed prefixes. Recovery allocates a fresh bounded continuation with the current revision and materialized topology. A permanently exhausted fresh-call allowance raises terminal `ExecutionPlanValidationError`, preserving the causal diagnostic. It does not leave a nonresumable task pretending to await another recovery attempt. Cached complete model responses remain reusable at the cap. A completed stream terminal result retained before metadata sealing is also validated and sealed without a fresh call; incomplete or uncertain streams require continuation. Sealed planning performs no further provider calls. + +The pure validator now accepts `initialDepth = 1` as an optional fourth argument. It rejects invalid or exhausted inherited depth before catalog callbacks, carries depth into existing dependency/static-nesting guards, and keeps the catalog digest independent of episode depth. Planner options carry `depth`; every candidate and a provider preflight use it. The parent runtime is responsible for passing each child's accumulated absolute episode depth. This closes the dynamic nested-planner reset that otherwise allowed each proposal to restart its depth allowance. + +Verification on the latest owned state: + +- Initial planner/parser stubs produced 19 failing cases and five expected rejection cases that already passed. +- Targeted RED checks reproduced stalled-source cancellation timeout, wasted model corrections after a rejected commit, duplicate same-owner planning, missing malformed-frame evidence/counts, cached stream sealing at the attempt cap, inherited dynamic depth reset, split-surrogate UTF8 overcount, and a simultaneous admission loser clearing the winning pending reservation. Already-active admission errors now bypass interruption cleanup so they cannot mutate another call's planning state. +- Latest focused run passed 97 cases across proposal validation, commit, planner, parser and the coordinator's planning adapter integration. +- Harness `tsc --noEmit` and Biome checks passed on the latest owned source/test files. + +Current logs are `/tmp/agentium-execution-planner-green.log`, `/tmp/agentium-execution-planner-tsc.log` and `/tmp/agentium-execution-planner-biome.log`. Targeted RED logs are `/tmp/agentium-execution-planner-hardening-red.log`, `/tmp/agentium-execution-planner-owner-evidence-red.log`, `/tmp/agentium-execution-planner-cache-seal-red.log`, `/tmp/agentium-execution-planner-depth-utf8-red.log`, `/tmp/agentium-execution-planner-admission-race-red.log`; the initial RED log is `/tmp/agentium-execution-planner-red.log`. Persistent process recovery, matched offline evaluation, full repository checks, built-package consumption and public exports remain coordinator/evaluation-worker owned. No backend launch, paid model call, source commit, push or deployment was performed by this worker. + +## Review follow-ups + +The coordinator additionally assigned an isolated core cleanup correction. `RootExecutionLease.cleanup()` shares `run()`'s released/concurrent/nested-work ownership checks and AsyncLocalStorage scope, but permits already-admitted finalization after cancellation or deadline. It does not reserve another slot or work attempt. Ordinary `run()` retains its active gate, and release still waits for the callback to settle. The standalone provider wrapper now calls `cleanup()` around iterator return before releasing its permit. Three targeted RED regressions established absent cleanup and finalizer nested-dispatch bypass; 29 core root tests subsequently passed. Core `tsc --noEmit` and Biome passed, with logs `/tmp/agentium-root-cleanup-{red,green,tsc,biome}.log`. The coordinator owns the harness driver's corresponding cleanup change and subsequent build. + +Catalog descriptors now pin description, strict mode, raw JSON schema, input examples and concrete sandbox settings. Sandbox environment names remain visible, while each value is represented only by its durable hash; raw host environment credentials are neither persisted in descriptors nor sent in planner catalog messages. Agent-local tool comparisons preserve executable/schema/approval/output-transform identity and allow canonical equivalence of finite copied sandbox/schema/example data. Changed permissions or model-visible contracts fail admission. Two targeted RED tests reproduced cloned-sandbox rejection and missing descriptor identity; the subsequent focused run passed 119 tests across these proposal cases, planner/commit, the coordinator's adapter integration and core cleanup. Latest Biome checks passed; harness TypeScript checks showed no owned-file errors but still reflected coordinator-owned graph recovery changes and core declarations awaiting rebuild.

This report is a proposed implementation contract, not verification of a new capability. + +## Existing foundations and concrete integration points + +| Foundation | Current behavior and source | +| --- | --- | +| Stable task/run identity | `packages/core/src/durable/types.ts:6–42` separates tenant, actor, session, run, root and parent run identity; immutable manifest/input/driver/policy/grant bindings are available. Definition digest normalizes default budgets and excludes mutable extensions (`durable/store.ts:58–76`). | +| Atomic fenced task state | `DurableTaskStore.update` has a pure synchronous mutation and optional worker fence (`durable/types.ts:105–120`). `store.ts:122–129` rejects expired or superseded owners; `store.ts:131–223` enforces immutable task fields and monotonic audit/counters/action transitions. | +| Persistent backend | `MongoDBDurableTaskStore` (`durable/mongodb.ts:18–25`) advertises durable, CAS, fencing and durable outbox. It uses majority+journal acknowledgements (`:39–43`), server time (`:51–55`), revision CAS plus an atomic lease-expiry condition (`:101–119`). One task is one bounded aggregate, default 2 MB. No cross-task transactions. | +| Local deterministic backend | `InMemoryDurableTaskStore` (`durable/store.ts:225–233`) is explicitly `durable:false`. It is useful for decision tests but cannot establish process-crash recovery. | +| Ownership/recovery | `DurableTaskSupervisor.claim` (`durable/supervisor.ts:51–81`) advances the root fence, appends worker attempts and converts interrupted `executing` actions to `unknown`. `run` polls cancellation and renews leases (`:124–154`), but refuses to enter its handler while unknown actions exist (`:155–157`). Reconciliation must therefore run under a claimed fence before invoking the graph, or the supervisor needs an explicit reconciliation hook. | +| Logical effect ledger | `DurableActionLedger.prepare` (`durable/actions.ts:54–104`) hashes connector version, destination, arguments, identity, policy revision and grants. A reused action ID with different inputs fails (`:69–74`). Its destination idempotency key is stable per logical action (`:80`). `execute` persists dispatch intent before dispatch (`:118–160`), returns saved confirmed receipts (`:114`), blocks executing/unknown actions (`:115`), marks exceptions after dispatch unknown (`:173–186`) and supports fenced reconciliation (`:190–215`). | +| Real idempotent destination | `MongoDBDurableDocumentConnector` (`durable/mongodb-connector.ts:13–60`) writes an append-only document with unique `_id`, checks prepared hashes and reads a receipt. Its reconciliation intentionally returns `unknown` for absence because an old request might still arrive. This is a supported document-effect binding, not generic email/payment/shell safety. | +| Run evidence and snapshots | `DurableRunRecords` (`durable/records.ts:78–127`) appends bounded sequenced events. Artifacts are immutable and digest checked; blob write precedes a fenced reference commit (`:139–227`), leaving only possible orphan blobs. `JournaledDurableTaskStore` (`:232–275`) records task lifecycle changes in the same CAS. Event retention is bounded and cannot be the authoritative source of graph recovery state. | +| Current graph lifecycle | `workflow/graph-runner.ts:223–265` materializes and validates an episode but keeps all phases/patches/results in memory. `:282–334` settles node outcomes; `:344–378` computes dependencies and node inputs before dispatch. These are the natural materialize/start/settle/block persistence hooks. | +| Step and episode scope | `workflow/step-runner.ts:90–143` creates graph/repeat execution paths and selects step implementations; `:157–200` runs Agent nodes; `:203–219` sends functions through `ExecutionServices.dispatchEffect`; graph and repeat methods are at `:285` and `:311`. Current paths give attribution, not durable effect identity. | +| Current checkpoints | `workflow/workflow.ts:271–320` only saves after completed top-level steps; input envelope validation is at `:15–46`. Keep these formats compatible; they do not supply unfinished-graph recovery. | +| Harness boundary | `ExecutionServices` (`agent/execution-services.ts:20–76`) supplies controlled model and stream calls, tools, policy and `dispatchEffect`. `HarnessRuntime` explicitly rejects durable drivers without a recovery adapter (`harness/src/runtime/driver.ts:310`). `workflowDriver` advertises `durable:false` (`harness/src/drivers.ts:19–24,111–155`). Merely setting a capability flag is unsupported. | +| Root budgets | `HarnessBudgetLedger` (`harness/src/runtime/budget.ts:82–207`) tracks calls/tools/tokens/protected finishing capacity and unknown usage, but has no restore API. Runtime constructs a fresh ledger (`runtime/driver.ts:451`). Supervisor task token/cost reservation (`durable/supervisor.ts:169–180`) is separate, monotonic and manual; it does not retain harness model/tool counts or deadline automatically. | +| Agent tool boundary | Agent merges its own configured/resolved tools with service tools (`agent/agent.ts:484–516`) and delegates models through services (`:518–537`). However LLMLoop executes its own ToolExecutor directly (`agent/llm-loop.ts:610–611,985–986`). Wrapping only `services.dispatch` does **not** intercept all Agent node effects. The actual authorized operation is `tools/tool-executor.ts:354–362`, after argument validation/policy/approval and argument-mutation checks (`:249–336`). | + +## Smallest coherent durable protocol + +Reuse the task aggregate and action ledger; add a reserved, validated versioned graph extension rather than a second store or bespoke scheduler. A durable workflow adapter must require `durable`, atomic updates, CAS and fencing capabilities, plus verified executable/effect bindings. The non-durable `Workflow`, `Agent` and checkpoint callers stay compatible. + +### Bindings and admission + +A host-owned immutable catalog maps explicit binding IDs and versions to functions, Agent configurations and tool connectors. Catalog descriptors contain input/output validators and effect-recovery mode. Serialize descriptors/references only; functions, clients, credentials and signals remain outside records. An admitted definition binds workflow version, catalog descriptor digest, driver version, root identity, original input digest, grants/policy revision, resource limits and absolute deadline. + +Before any resumed effect, validate this envelope, the materialized proposal, every binding version and stored node input/output. Reconstruct runtime services from host-owned bindings and recheck current grants; a persisted grant reference is not proof that a revoked grant is still valid. Unknown operations, unversioned unsafe callbacks, arbitrary local Agent tools and unresolved schema references fail before admission. A “pure” binding is a host declaration with a real contract; it cannot make an effectful callback safe by naming convention. + +Declare supported categories explicitly: + +1. Pure JSON function nodes whose implementation version and validators are host bound; restarting after an interrupted computation has no external effect. +2. Controlled function nodes bound to a `DurableActionConnector`, with destination-enforced idempotency or reconciliation and a retained output/receipt resolver. +3. Agent nodes using recorded model decisions and only approved pure or durable tool bindings. Tool-free Agent nodes still need persisted model-budget accounting. Unsafe hooks, dynamic tool resolvers, remote handoff/subagents or callbacks that bypass the controlled port need a declared supported adapter or must be rejected. + +This declaration covers both required node kinds while making unsafe operations visible. It is not acceptable to advertise general durable graphs with function-only interception. + +### Authoritative record + +Suggested extension fields: schema version, definition/catalog digests, root limits and counters, original absolute deadline, persisted cancellation, current scheduler revision, materialized episode records, bounded plan-revision history, repeat decisions/counters, node records, recorded model decisions, effect references and superseded/late evidence. Validate all restored JSON at runtime. Use the existing finite canonical JSON contract and reject corruption/version mismatch rather than casting stored data. + +Each episode records a stable scope, entry input, materialized DAG, declaration/topological order, dependency decisions and merge mode. Each node records logical identity, binding/version, input and input digest, lifecycle, output patch, StepResults, plan revision and execution-attempt generation. Persist input/readiness and `running` atomically **before** effects. Persist owned output and terminal phase atomically before releasing successors. Rebuild merge ownership and readiness from the authoritative terminal records; do not trust a saved aggregate state without checking provenance. + +A stable node identity is root run + graph/repeat scope + node ID + logical definition generation. A logical effect identity is that node identity + recorded operation position/call ID, bound to connector/version/destination/argument digest. Attempt UUID, worker ID or root fence must never replace logical effect identity. Repeated dispatch of the same ID with changed inputs is rejected by the existing ledger. Attempt IDs and fences remain separate audit/ownership fields. + +### Interrupted Agent behavior + +Use a documented restart-from-node-entry protocol under recorded-decision playback. Persist a complete provider-valid model response and its request/configuration digest before making any tools from that response eligible. On recovery, rerun the Agent loop using those saved complete responses and effect receipts; do not make new model calls or rerun confirmed effects for replayed positions. Subsequent unfinished model calls may be sampled again only after accounting for the interrupted call's retained reservation/unknown charge. This is recovery using recorded decisions, not arbitrary exact playback of all runtime behavior. + +The ToolExecutor must expose a durable invocation boundary **after** validation, policy, approval and argument integrity checks, carrying ToolCall ID plus child RunContext. A durable service/catalog adapter can then intercept both service tools and Agent-local tools. The existing `services.dispatch(call)` lacks child context and is not the Agent loop's dispatch point. Keep delegated node scope in metadata or an explicit immutable context identity, and preserve binding/call/input checks even on receipt reuse. + +Persist raw tool output/receipt before any potentially failing model-output conversion, observer, cancellation check or node finalization. The current ToolExecutor can lose successful raw output when later transformation or cancellation fails; its durable boundary must retain the evidence. JSON-only durable binding outputs avoid artifact/session pointers that cannot be resolved after process death. Provider `raw`, SDK objects, API keys and AbortSignals are not automatically durable JSON. + +### Recovery rules + +| Node state | Recovery action | +| --- | --- | +| Pending | Recompute readiness from recorded predecessor states, validate original materialized input binding, and admit under retained budgets. | +| Completed or skipped | Reuse saved output/result; never rerun its executable. Revalidate output and merge ownership. | +| Running, no dispatched effect | Advance node attempt generation and restart pure work or recorded Agent decisions within retained allowances. | +| Running with confirmed effects | Restore/replay their receipts and resume the recorded node operation; no remote redispatch. | +| Running with executing/unknown effect | Reconcile under current root fence before retry. If unresolved, preserve an explicit recovery-required outcome and evidence; do not convert it to ordinary step failure and quietly retry. | +| Failed | Preserve failure. Retry only an explicitly bounded host/node policy; never reuse a terminal task by silently resetting its state. | +| Cancelled/cancel requested | Keep cancellation persisted; stop new admissions, reconcile executing/unknown effects, and retain late evidence. A local abort is not remote rollback. | +| Superseded | Old attempt outputs cannot update current node state; retain action/late-result evidence. Existing effects remain historical facts. | + +Root lease fencing protects worker commits; node generation/plan revision protects superseded attempts in the **same** root lease. Both checks must be in the settle CAS. A stale worker may still finish a remote request, so destination idempotency/reconciliation remains mandatory. + +### Budgets, deadlines and repeated/streamed episodes + +Persist the full harness accounting needed to restore ordinary and protected finishing capacity—not only a public remaining snapshot. Model/tool admissions and bounded token reservations must commit before dispatch; crash recovery retains outstanding reservations conservatively as unknown usage until authoritative settlement. Never initialize a new zero ledger with the original full allowance. Original absolute deadline and cancellation state are immutable across retries/recovery; use backend time for fenced admission where practical. Supervisor `maxAttempts` counts worker claims separately from graph node-attempt/plan-expansion limits. + +Persist repeat guard decisions before dispatching another body, completed iteration count, and each materialized graph body. Do not reevaluate an already recorded historical predicate or factory after recovery. A new decision may read only settled recorded observations. Stable scope includes the iteration so repeating an intentional operation gets a different logical identity without resetting root limits. + +For streamed planning, accept bounded framed **complete committed proposals/revisions**, not arbitrary token prefixes. Validate each revision's full executable graph, bindings, refs, cycles, sizes and limits before CAS commitment. Previously running/completed node definitions, inputs, dependencies and owned outputs are frozen. Pending definitions may change only under a new generation with transitive readiness/input recomputation and an audit link; unresolved references never execute. Preserve removed/superseded nodes and prior effect records. A planner stream crash resumes the last committed revision; an incomplete fragment has no executable authority. Retain causal observations and proposed/validated plans, with bounded revision/correction budgets. Planning model calls consume the same root allowance. + +For root scheduling, avoid permits for graph/repeat/Agent containers while they wait on descendants. Limit real model/tool/function leaf operations; lifetime expansion and execution attempts are separate monotonic units. A function binding that launches controlled descendants cannot hold their shared permit throughout the wait: either classify it as a container, enforce a leaf-only callback contract, or explicitly suspend its permit. Persist durable counters and in-flight ownership; recover stale permits only through fenced attempt recovery, not by erasing evidence of unknown external work. + +## Backend availability and real crash checks + +Read-only local discovery found `/opt/homebrew/bin/mongod`, `/opt/homebrew/bin/mongosh`; `mongod --version` reports **8.0.1, aarch64**. No listener appeared on 27017 or 27319. This is evidence that a disposable local Mongo process is plausible, not that a database connection or durability contract was tested. Installed `mongodb`, `tsx`, and `better-sqlite3` peers are present in the worktree through links to the original checkout's dependencies. `sqlite3` is installed, but there is no existing SQLite `DurableTaskStore`; cost/storage SQLite adapters do not satisfy this graph recovery contract without new implementation. Mongo is the existing supported persistent task backend and should be preferred. + +Existing tests `durable/__tests__/mongodb.integration.test.ts:30–69` fork fresh `tsx` workers with IPC barriers and SIGKILL, enabled by `AGENTIUM_DURABLE_MONGO_TEST=1`; default URI is `mongodb://127.0.0.1:27319/?directConnection=true`. They already cover competing ownership, stale worker fencing, CAS clients, prepared intent before dispatch, effect before receipt, and approval/cancellation restart (`:85–184`). Existing fixture is `durable/__tests__/fixtures/crash-worker.ts`; adapt this pattern to real Workflow + HarnessRuntime + durable adapter. + +Use a task-owned temporary Mongo data directory, isolated port and generated fixture database; the existing tests delete only `agentium_durable_fixture_*`. The coordinator owns server startup/cleanup and whether test-local cleanup is within authorization. Never use an unknown user's production database or kill an unrelated server. A standalone journaling Mongo server proves local process crashes with persisted server state; it does not establish replica-set failover, backup recovery or power-loss guarantees. + +Required fresh-worker additions, using IPC barriers at actual persisted/remote boundaries: + +- Crash after validated graph/start intent but before effect dispatch: restart admits once. +- Crash after unique Mongo destination acceptance before action receipt: reconcile one document; no unsafe second operation. +- Crash after action receipt before node settle: restore recorded output and complete node without redispatch. +- Complete sibling A, interrupt B: retain A's output and effect, recover only B, preserve dependency ordering. +- Interrupt an Agent after recorded model tool request and confirmed tool receipt: new process replays recorded decisions/receipt and proceeds, with local Agent tools included. +- Interrupt a model request before recorded response: reserved calls/tokens remain counted and next call respects remaining budget/deadline. +- Expire/supersede worker and attempt a late settle: CAS rejects stale fence; destination receipt remains inspectable. +- Persist cancellation across death with an unknown effect: no new work, explicit unresolved until reconciliation. +- Crash after a repeat decision/body materialization: same iteration/episode reused and counters never reset. +- Crash after streamed revision commitment before admissions: same validated revision reloaded; incomplete later fragment ignored without erasing its diagnosis. +- Identity/catalog/version/input corruption on recovery fails before model/tool admission. +- Nested graphs/repeats and Agent batches obey root concurrency; crashed permits reclaimed via fenced ownership; unknown effects remain evidenced. + +Acceptance must inspect actual destination counts, saved completed node records, effect/input digests, root counters/deadline, committed revision and stale commit rejection.

Automatic safe reconciliation needs a deliberate entry hook; otherwise report unresolved honestly. +- Ordinary StepRunner catches arbitrary errors and turns them into failed StepResults (`workflow/step-runner.ts:125–141`).

Reject bounded expansion before unsafe admission, or use immutable blob references committed after successful writes. Do not silently drop recovery data. +- Raw callback/Agent hooks can execute captured external resources outside the SDK; the durable binding contract must reject unsupported unsafe operations and disclose trusted host responsibilities. +- Model/token reservation and concurrency permit ownership need persisted admission before remote work; restoring only a final snapshot leaves crash holes. +- Scope paths, fresh UUIDs, model tool-call IDs without recorded requests, and timestamps alone are not durable logical effect identities. +- Exactly-once external execution, arbitrary connector safety, power-loss recovery and paid/live model quality are not established by the proposed implementation or existing tests.

Ordinary Workflow checkpoints remain completed top-level boundaries. +- Opt-in `ExecutionGraphRuntime` in `@agentium/harness`: versioned host executable catalogs, JSON DAG proposals, fenced node/model attempts, retained outputs, Agent decision replay, repeat decisions, and effect intent/receipt reconciliation over the existing durable task store. +- Shared root execution admission across nested graphs, repeats, Agent tools and planning, with FIFO cancellation/deadline handling and monotonic concurrency, expansion, dispatch-attempt and revision limits retained across recovery. +- Optional tool-free model DAG planning with bounded validation/corrections and NDJSON revision frames.
