It is invalid +until the operator assigns real repositories, identities, absolute artifact paths +and an immutable reviewed controller release. No configuration is silently +installed into the live host. The existing execution deployment pin remains an +independent approval. Enforced mode forces dispatcher-only operation, even if a +legacy project override requests full automation. Self-directed review/deployment +jobs are not part of the qualified worker boundary. + +`observe` preserves the authenticated legacy single-operator installation and +reports that enforcement is absent. `enforce` denies unmanaged mailbox work, +unmapped repositories, unqualified releases, unavailable isolation, exhausted +service targets and unreconciled prior usage. It does not fall back to trusted +host execution. Legacy model formatting is disabled in enforced intake; original +human intent is retained. Programs use a registered, measured planning adapter, +not an unmetered host CLI fallback. + +Repository-to-tenant and task-type-to-profile mappings come only from operator +config, never issue bodies or model output. Parent/child work cannot cross tenant +boundaries in enforced mode; neither can declared dependencies. Reuse YAML templates for profiles, but give each +tenant its own profile names and release approvals. Customer-specific external +tool targets still need exact grants in the goal ancestry. + +Principals have explicit tenant scopes and roles: reader, operator, approver, +billing, memory, administrator. Unknown identities fail closed when principals +are configured, even in observe mode. CLI identity is the actual `local:`; +Telegram uses its authenticated immutable `telegram:`, not a mutable +username or shared group ID. Legacy global Telegram commands and callback buttons +require the controller administrator role. Goal commands remain tenant scoped. +The shared private dashboard is an **operator-wide view**, not a customer portal. +Do not give its bearer credential or host access to tenant-only users. + +## Traces And Measured Usage + +Worker attempts, model-gateway calls, isolated tools, registered actions and acceptance verification +have persisted spans with common goal/revision trace IDs and parent span IDs. +Worker restarts do not lose those records. Errors retain their type, not raw +provider messages. Allowed attributes exclude prompts, tool inputs, credentials +and model outputs. A running span after a crash stays unfinished, not successful. +The model adapter receives a W3C-format `traceparent` for downstream propagation. +These are local traces, not an installed distributed tracing collector. + +`model_gateway.call_model` accepts a controller-owned active attempt and invokes +an operator-owned adapter using fixed argv and structured JSON stdin. The adapter +receives `{attempt_id, traceparent, request}` and returns `{output, usage}`. +Only named environment keys reach it. Place adapter code outside worker-writable +paths; Python adapters should use `-I` to exclude workspace import paths. Trusted +adapters must return provider metadata, never ask a model to estimate its cost. + +Usage schema: + +```json +{"provider":"provider-name","account":"nonsecret-account-reference","request_id":"provider-request-id","model":"model-version","input_tokens":123,"output_tokens":45,"cost_nano_usd":123456,"final":true} +``` + +Costs use integer billionths of USD in receipts. Provisional receipts may have +null cost. Exact replays are idempotent, final receipts are immutable, and a +provider/account/request identity cannot be charged to two attempts. Token counts +are measured, not estimated from characters. Include caching or other billed +categories in the actual total charge; the two token counters are not a price +calculator. Account references must never be credentials. + +A finished attempt's cost remains unknown until a trusted collector seals the +**complete list** of receipt keys. One observed call is not full coverage. Sealing +updates the existing delivery cost and budget accounting atomically. Additional +requests cannot be appended after sealing. Incorrect final receipts require an +audited reconciliation, not silent overwriting. Existing CLI agents that do not +expose a complete measured request manifest remain unmetered; use an instrumented +adapter or an authorized billing collector. The implementation does not invent +provider billing access or invoice data. + +```bash +python -m orchestrator.reliability_ops usage --tenant example --attempt ATTEMPT --file receipt.json +python -m orchestrator.reliability_ops seal --tenant example --attempt ATTEMPT --file receipt-keys.json +python -m orchestrator.reliability_ops traces --tenant example --goal GOAL +``` + +Adapter calls have a bounded timeout and output size; descendants are killed on +exit or timeout. A timed-out effect is uncertain and cannot be blindly repeated. +There is no claim of provider-side exactly-once delivery. Runtime reservations +are admission controls, not absolute provider spending caps. + +## Memory And Isolation + +Tenant facts have provenance, writer identity, revision and expiry. Updates use +compare-and-swap; stale writers cannot overwrite newer facts. Reads are tenant +scoped and expired facts are removed. The coordinator also purges expired facts. +Only a memory-role principal may change retained facts. Prompt injection labels +memory as untrusted evidence, never as authority. Intent and decision history +remain separately owned by the goal controller. + +```bash +python -m orchestrator.reliability_ops memory-put --tenant example --key fact --value 'Reviewed fact' --source 'source-reference' --revision 0 --ttl 86400 +python -m orchestrator.reliability_ops memory-list --tenant example +python -m orchestrator.reliability_ops memory-delete --tenant example --key fact +``` + +Memory retention cannot exceed the tenant profiles' configured limit. Live row +deletion does not erase previous backups; backup retention is a separate operator +responsibility. Secrets must not be stored as facts. Redaction is defense in depth, +not a guarantee that arbitrary sensitive personal information is detected. + +Enforced workers run in Bubblewrap user/mount/PID namespaces, with capabilities +dropped, a new home and temporary directory, and only their worktree writable. +Host home, controller DB, other workspaces and inherited credentials are absent. +Git metadata is masked so workers cannot redirect later controller Git commands. +Repository tests and configured-command verifiers use the same boundary. Git +publication disables hooks/fsmonitor and refuses executable filters/included +config at any Git configuration level. Handoff files reject symlinks, hard links, +special files and oversized content before privileged reads or writes. A missing +or kernel-disabled sandbox is a failure, not a fallback. + +Enforced profiles require network-off tools with no provider credentials. A +controller-owned agent loop calls the measured model adapter outside the tool +sandbox, then executes only structured `argv` tool proposals inside it. The model +cannot run a privileged host shell or connect to the operator dashboard. Tool +turns, request/output sizes and total attempt time are bounded; pause/cancel also +stops an active model adapter or tool process group. Complete observed usage +manifests are sealed on attempt completion; crashes remain unreconciled. + +Adapter `output` for workers must be exactly `{"tool_calls":[{"argv":[...]}]}` +or `{"final":{"status":"complete","summary":"...","blocker_code":"none"}}`. +Planning adapters return a structured work-package plan instead. Provider-specific +adapters translate this request/response protocol; raw legacy CLI agents are not +quietly substituted in enforced mode. Install executable dependencies through +explicit read-only mounts. Keep provider credentials only in the trusted adapter's +named private environment, never argv. This is not a sandbox against a compromised host +kernel, malicious host administrator or malicious operator-owned adapter. Do not +run legacy unsandboxed review/deployment automation over untrusted artifacts; +dispatcher-only mode keeps those separate from this managed execution boundary. + +Queue intake and execution select the profile's adapter, not whichever legacy +CLI happens to be installed. The adapter's name is reported as the worker +identity. Failures do not silently switch to an unqualified CLI. Reconcile any +uncertain billed request before changing providers or retrying. + +## Evaluation And Release Gates + +Every profile binds a controller Git SHA, evaluator, test artifacts, rollback +plan and incident playbook. Their hashes and the adapter registries form the +evidence fingerprint. Changing them invalidates approval. The executing checkout +must match the SHA and have no tracked modifications. A config string cannot +pretend to be the actual deployed release. + +The evaluator is a bounded operator-owned executable. It returns numeric quality, +sample count and boolean results for named scenarios. Required scenarios include +end-to-end delivery, restart recovery, duplicate effects, denied actions, stale +revisions, provider failure, restore, isolation, approval expiry and the complete +measured-model/isolated-tool/independent-verification flow. Missing, +failed, timed-out or skipped scenarios cannot pass. `bin/evaluate_orchestration.py` +runs actual controller tests and emits an **engineering** score, not a business +quality score. Its providers are local fixtures and never enter live metrics. +Ordinary test runs may skip unavailable host isolation; the qualification report +maps that skip to a failed mandatory scenario, never an eligible release. +Add task-specific scenarios and reference datasets through the evaluator/artifact +contract when qualifying a business workflow. + +```bash +python -m orchestrator.reliability_ops evaluate --tenant example --profile example-code +python -m orchestrator.reliability_ops approve --tenant example --profile example-code --evaluation RUN_ID --reason 'Reviewed evidence and recovery plan' +``` + +The approver must differ from the evaluation initiator. Only the latest passing, +fresh evaluation of unchanged artifacts can be approved. New failed evaluations +override older passes for eligibility. Quality loss from the approved baseline +blocks admission even when the absolute minimum still passes. Evidence expires. +Optional periodic evaluation uses the existing coordinator cadence and runs only +when explicitly configured; no cron is installed by this change. Running managed +workers recheck their release gate every five seconds. + +## Service Commitments + +The template gives separate code, research and external-action profiles explicit +success-rate and end-to-end latency targets, a rolling window, sample minimum and +memory retention. These values are configurable operating targets, not a signed +customer SLA. Define business quality and contractual obligations with the client. + +Success uses independently accepted terminal tasks, not model completion claims. +Cancelled tasks and historical imports are excluded; the denominator and sample +count are visible. Latency includes waits. Open overdue work is an immediate +breach. Too few completed samples means insufficient data, not 100% reliability. +Service breaches stop admission of new goals. Already-started goals can finish or +recover within their original authority and budgets, rather than being trapped +forever by their own overdue status.
