diff --git a/CHANGELOG.md b/CHANGELOG.md index 0381527..dd69577 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -2,8 +2,356 @@ ## [Unreleased] +### Fixed + +- **P11 identity namespace, non-success, overflow, and content-free failure.** + Provider-report ArtifactRef paths now bind `provider`, `model`, and + optional child-envelope digest into a P07-strict namespace so two + identities cannot share a path or ref. Failed/cancelled ACP turns never + publish accumulated partial text as complete. Collector overflow at the + raw class cap is handled inside `attachLocalProviderResultSink` with + typed content-free evidence and does not rewrite the provider terminal + or claim complete output. `contentFreeSinkFailureV1` allowlists closed + code/path values and uses one generic bounded message. + ### Added +- **Provider registry composition authority.** Adds the additive v3 + `provider-registry.mjs` module (P23): the deterministic, closed + composition authority behind provider selection. It registers exactly the + four accepted `ProviderDriverV1` adapters (P18 Grok ACP `grok`, P19 + Cursor Local `cursor-local`, P21 Cursor Cloud `cursor-cloud`, P20 DSH + ACPX `dsh`) in the frozen P02 grammar slot order, re-deriving that + vocabulary from the accepted grammar leaf so it cannot drift. Selection + (`resolveRegistrySelectionV1`) maps an exact `{provider, model}` pair + onto one entry under `exact_closed_slot_no_fallback` with no preference + walk, substitution, fallback, retry, or replay; closed model lists are + enforced against accepted constants and grammar-owned models stay with + their adapters, so no vocabulary is widened. Composition + (`composeProviderDriverV1`) gates the provider before reading any option + byte, quarantines hostile inputs content-free (Proxies, accessors, + symbols, non-enumerables, exotic prototypes, unknown keys fail closed + without running caller code), delegates to the one exact accepted factory, + and returns its value untouched so adapter lane stores, evidence maps, + and identity binding keep accepted semantics. Inventory + (`describeProviderRegistryV1`) quotes each accepted module's own describe + surface in detached frozen clones instead of restating capability claims. + The P22 future-harness template/conformance kit is inventoried as + mock/conformance evidence only: never a fifth provider slot, never + selectable, never composable here. The registry performs no ambient + discovery (no filesystem, environment, PATH, network, clock, random + source, process, or dynamic import), performs no supervisor/server/ + scheduler/durable-store cutover, claims no live transport qualification, + merge/PR authority, or direct mode, and changes no version or 3.2.1 + legacy behavior. Coverage lives in `test/r1-provider-registry.test.mjs`, + `test/r1-provider-registry-adversarial.test.mjs`, and + `test/r1-provider-registry-integration.test.mjs`; boundaries live in + `docs/provider-registry.md`. + +- **Git authority policy.** Adds additive v3 `git-authority.mjs` (P28): a + closed immutable `GitAuthorityPolicyV1` for protected/default refs, the + `codex/run-/` lane namespace, credential-free + repository/ref identity, and operation authority. External agents and + providers cannot merge, rebase, push, create PRs, mutate + protected/default refs, create tags/releases, or obtain + credential/remote mutation authority. Default-branch targets, merge + histories, namespace/confusable/ref-grammar attacks, unknown + operations/keys, proxy/accessor inputs, and bounds abuse fail closed. + Verdicts and P13-compatible facts/discrepancies are content-free and + never echo repository paths, URLs, credentials, provider text, or + hostile refs. This is policy at the authority seam only: no Git + mutation, no P29 credential isolation, and no P30 protected-ref audit. + Coverage lives in `test/r1-git-authority.test.mjs` and + `test/r1-git-authority-adversarial.test.mjs`. +- **Local provider result sink.** Adds additive v3 + `local-provider-result-sink.mjs` (P11) that routes final local Grok ACP, + Cursor Local ACP, and DSH ACPX/CLI provider output into the accepted + P08/P09 raw+sanitized artifact store through one provider-neutral sink, + binding exact `run_id` / `assignment_id` / `provider` / `model` / optional + child-envelope digest identity into the ArtifactRefV1 path. The complete + transport-available result is stored up to the existing class cap; older + output is never silently discarded, empty results stay unpublished, and a + source that the upstream already clipped is persisted with truthful + `source_truncated` / `complete` provenance. Only sanitized artifacts are + model-readable. The receipt is detached deep-frozen content-free + metadata (raw/sanitized refs, P09 provenance, digests, counts, + truncation) plus a default inline tail of at most 4,096 UTF-8 bytes + derived through the accepted P10 sanitized reader and aligned on a valid + UTF-8 boundary, with inline clipping recorded separately from upstream + truncation. The ACP worker is the only serialized seam: it preserves + 3.2.1 `task.result` / `result_*` and event/terminal shapes, attaches + optional `provider_result_sink` metadata only after provider terminal + publication, and records typed content-free evidence on sink failure + without inventing completion or replaying provider work. Coverage lives + in `test/r1-local-provider-result-sink.test.mjs` and + `test/r1-local-provider-result-sink-adversarial.test.mjs`. +- **Atomic raw/sanitized artifact store.** Adds the additive v3 + `artifact-store.mjs` module for W4-P08: it binds validated ArtifactRefV1 + declarations to real bytes under one caller-supplied existing private store + root, mapping each strict relative path segment-for-segment into disjoint + `raw/` and `sanitized/` namespaces (`content/` plus a strictly parsed + canonical sidecar per artifact), so raw evidence and model-facing + projections never collide even at one path and no parallel ref or path + schema is introduced - references are parsed with `parseArtifactRefV1` and + nothing else, so traversal, absolute paths, reserved device names, + separator look-alikes, and Unicode tricks inherit the exact P07 denials. + Sources are intrinsic Buffer/Uint8Array views or bounded async iterables of + such views; proxies, subclasses, SharedArrayBuffer backings, strings, + accessor-shaped iterables, and arbitrary class instances are denied before + any byte is read. Declared byte length and SHA-256 are treated as untrusted + claims: bytes stream into an unpredictable owner-only same-directory + temporary while the class cap (sanitized 256 KiB, raw 32 MiB) is enforced + on every chunk before it is written, actual length and digest are computed + from the streamed bytes, and both must match the declaration exactly before + publication; the temporary is fsynced, published by exclusive hardlink that + refuses to clobber, unlinked, and the parent directories fsynced, so no + partial artifact ever exists under an authoritative name. Exact same + validated ref plus bytes is idempotent across concurrent submissions (one + deterministic winner plus idempotent losers behind a per-root operation + chain); conflicting content at one location, the same digest under + different metadata, or any other competing publication fails closed with + typed content-free errors and leaves the authoritative state untouched, + rolling back a race loser's own link only when the platform proves the + inode is ours. Roots and parents use descriptor/no-follow discipline - + O_NOFOLLOW|O_DIRECTORY opens, device/inode identity brackets, lstat-walked + 0700 parent chains re-proven after publication - rejecting missing, + non-private, symlinked, replaced, and swapped roots and parents wherever + provable. Verification and audit stream stored bytes in fixed chunks solely + to recompute length and digest (never returning or buffering content), + enumerate with bounded per-directory entries, files, depth, and total + audited bytes, and condemn leftover or torn temporaries (a reserved name + grammar artifacts may never spell), orphaned or duplicate sidecars, + symlinks, hardlinks, FIFOs and other non-regular entries, foreign names, + truncated or oversized content, malformed or misplaced metadata, and + content swapped under a path; audits return detached frozen metadata plus a + framed inventory fingerprint that restarts reproduce exactly. Receipts, + verdicts, and reports are deep-frozen, content-free, and never echo the + store root, artifact bytes, or operating-system errors. Out of scope and + unclaimed: P09 sanitization, the P10 reader, the P13 evidence bundle, + cleanup, scheduler/provider/supervisor wiring, and protected references; + a torn store stays torn and fails closed until an operator acts. Coverage + lives in `test/r1-artifact-store.test.mjs` and + `test/r1-artifact-store-adversarial.test.mjs`. +- **ScopeVerifierV1 independent changed-path ownership, read-only, and + merge-commit verifier.** Adds an additive v3 `scope-verifier.mjs` module + for W16-P15. It consumes only trusted P14 `GitIdentityV1` snapshots and + P13 `VerifiedFactV1` / `EvidenceDiscrepancyV1` records, never provider + claims, and binds content-free `git_diff` / `head_sha` facts + (`platform_git` with `scope_match`, `read_only_no_changes`, and + `merge_commit_absence`). Observation is argv-only (`/usr/bin/git`, no + shell) through the P14 closed environment with system/global/caller + config and protocols disabled; output, time, and command counts are + bounded; typed errors never echo hostile bytes. It validates ownership + of additions, deletions, renames, and copies against trusted assignment + write-scope globs (P02 matcher), including overlap with other writers, + symlink/gitlink/type-change, Unicode NFC vs confusable separators, and + tracked plus untracked state. Read-only lanes must have no candidate or + worktree mutations. Merge commits and multi-parent histories fail. + Pre/post identity and worktree fingerprints detect observation races + and fail closed. It does not own P16A trusted command policy, P28 Git + mutation, P30/P35 composition, server/supervisor integration, network, + or merge/rebase/push/PR. Coverage lives in `r1-scope-verifier` and + `r1-scope-verifier-adversarial` tests plus disposable rename, merge, + symlink, gitlink, Unicode, untracked, and race fixtures. +- **GitIdentityV1 independent repository, ancestry, and merge-base + verifier.** Adds an additive v3 `git-identity.mjs` module for W13-P14. + It derives Git facts from the local repository through argv execution + (`/usr/bin/git`, no shell) and never from provider claims, then binds + repository identity, expected base ref/name, exact base SHA, candidate + head SHA, object types, reachability, ancestry, merge-base identity, + and rewritten/stale history into P13 `VerifiedFactV1` / + `EvidenceDiscrepancyV1` snapshots (`git_identity` and `head_sha` with + `platform_git` / `ancestry_check`). Observation uses a closed + environment that cannot inherit `GIT_*`, replace, graft, or config + influence; output, time, and command counts are bounded; typed errors + never echo hostile bytes. It rejects missing/wrong repos, symbolic-ref + drift, detached/unborn/ambiguous refs, non-commit objects, replace + refs, grafts, hostile names, extra keys, proxies/accessors, and bounds + abuse. It does not own P15 scope/read-only/merge-commit checks, P16A + trusted command policy, P28 Git mutation, or provider/workspace + dispatch. Coverage lives in `r1-git-identity` and + `r1-git-identity-adversarial` tests plus disposable forged/stale/ + rewritten fixtures. +- **Constrained verification runner.** Adds additive + `constrained-verification-runner.mjs` for W16-P16C. The module consumes a + genuine immutable P16B ExecutionIntent receipt plus trusted P16A + `VerificationPolicyV1`, creates a disposable verification workspace + disjoint from the candidate, and executes the exact owner-approved + absolute executable and argv once with `shell=false` and no PATH lookup. + The child environment is empty by default and receives only + policy-authorized bounded entries. The runner enforces timeout, + signal/termination fail-closed rules, stdout/stderr byte caps, + host-available process isolation (Linux user/pid/net namespace via + `unshare` on the default adapter), network deny/default (allowlists are + unsupported), and one execution only. Candidate Git identity and + filesystem are audited before and after; persistent + candidate/ref/config/worktree mutation fails closed. Temporary cleanup + deletes only the exact workspace this invocation created. Outcome + evidence is bounded, sanitized, and P13-compatible: host-observed exit + status is never upgraded from provider-reported PASS. The module is not + wired into the MCP server, supervisor, scheduler, or process-boundary + worker launcher, and it does not merge, rebase, push, open a pull + request, or mutate a protected ref. Coverage lives in + `test/r1-constrained-verification-runner.test.mjs` and + `test/r1-constrained-verification-runner-adversarial.test.mjs`. +- **Approved verification-command resolver.** Adds additive + `approved-verification-command.mjs` for W15-P16B. The module consumes an + immutable trusted `VerificationPolicyV1` from P16A plus a closed + Codex/owner selection of `command_id` and typed parameter values, and + returns a fresh frozen ExecutionIntent / ApprovedCommand receipt. Every + parameter is checked against the owner-authored domain (exact name set, + required semantics, types, enums, ranges, length, and path-segment + grammar). Expansion substitutes only whole-token `{name}` placeholders + from the owner argv template; there is no shell string, PATH lookup, + executable override, interpolation, substitution, globbing, or option + smuggling. Provider, profile, and manifest reported commands remain + evidence only: matching command-id or argv text does not authorize + resolution. Receipts bind policy identity, command-descriptor identity, + canonical parameters, executable path, exact argv, and inherited P16A + constraints without executing. Hostile containers fail closed with typed + content-free errors. Callers' objects are neither mutated nor frozen. + The module never invokes a shell, resolves PATH, opens a network socket, + reads arbitrary workspace files, mutates a candidate, or implements the + later P16C runner. Coverage lives in + `test/r1-approved-verification-command.test.mjs` and + `test/r1-approved-verification-command-adversarial.test.mjs`. +- **Trusted VerificationPolicyV1 schema and owner-authored policy loader.** + Adds additive `trusted-verification-policy.mjs` for W14-P16A. The module + owns a versioned immutable command catalog: each stable command ID binds + an owner-authored absolute executable path, a fixed argv template, typed + parameter domains, and explicit network, environment, mutation, timeout, + and output policies. Absent capabilities materialize as exact default-deny + receipts (no network, empty environment, no persistent mutation, bounded + time and output). Canonical identity/digest is framed through the P03 + `verification-policy.v1` / `verification-command-descriptor.v1` labels. + Profiles, manifests, and provider reports may name a command ID and typed + parameters only; executable paths, argv, shell text, environment, network + targets, mutation grants, and resource limits are rejected on that + untrusted surface. Hostile containers fail closed (proxies, accessors, + symbols, exotic prototypes, cycles, bounds, ambiguous IDs) with typed + content-free errors. The owner loader reads + `/codex-co-engineer/verification-policy.json` and never invokes a + shell, resolves PATH, executes a command, opens a network socket, mutates + a candidate, or implements the later approved-command resolver/runner. + Coverage lives in `test/r1-trusted-verification-policy.test.mjs` and + `test/r1-trusted-verification-policy-adversarial.test.mjs`. +- **ArtifactRefV1 and the strict relative artifact path policy.** Adds two + additive, pure v3 modules for W3-P07. `artifact-path.mjs` owns one + deterministic fail-closed question - is this string a strict portable + run-relative artifact path? - accepting only NFC, well-formed, + forward-slash, relative paths of 1..16 segments (128 UTF-8 bytes each, + 1024 total) with no backslashes, leading/trailing/doubled slashes, empty + or dot-only segments, colons (foreclosing drive, UNC, alternate-data- + stream, and scheme spellings in one rule), Windows reserved device stems + (`con`, `CON.txt`, `com1`, `lpt0`, `clock$`), edge dots/spaces Windows + strips, C0/C1 controls, invisible/format/bidi/tag code points, or solidus + look-alikes; the fixed validation pipeline raises identical first typed + errors from a closed 17-code vocabulary and never echoes hostile bytes. + `artifact-ref.mjs` binds the closed ten-key ArtifactRefV1 schema - exact + run/child identifiers reusing the accepted manifest grammars, artifact + kind bound to the P17 capability vocabulary, raw-vs-sanitized class with + class-dependent bounded-evidence caps (sanitized 256 KiB, raw 32 MiB), + declared byte length, lowercase-hex SHA-256, and closed media-type and + content-encoding enums - behind hostile-container hardening that rejects + live/revoked Proxies with zero traps, accessors without invoking them, + symbol keys, exotic prototypes, own undefined, sparse/extended arrays, + aliases/cycles, depth, and size before any effect, returns deep-frozen + detached snapshots, and frames SHA-256 digests over validator-owned + canonical JSON with explicit domain/version/label separation so key order + cannot change a digest while any value change must; ordering is a fixed + tuple comparator plus a bounded (64), duplicate-free batch orderer. Both + modules are pure schema/path policy only - no filesystem, network, or + process I/O - and neither claims that P08 artifact storage exists: + producers declare references, and only a later storage authority may bind + them to bytes. Coverage lives in `test/r1-artifact-ref.test.mjs` and + `test/r1-artifact-ref-adversarial.test.mjs`. +- **Grok ACP ProviderDriverV1 adapter (P18).** Additive `grok-acp-driver` + binds provider slot `grok` onto the accepted P17 preflight/launch/ + reconcile/cancel contract and the P05 13-field capability record + (`confirmed_launch`, `live_session_reply`, local managed worktree at + `run_base_sha`, `never_replay`, no merge/PR authority). An injected + bounded ACP transport keeps tests deterministic: launch is `dispatched` + only after an authoritative acknowledgement; any exception, timeout, + loss, or unusable receipt after spawn/dispatch intent is returned as + `dispatch_uncertain` and is never retried, replayed, or + fallback-substituted. Duplicate launch, digest-only launch, direct + mode, merge/PR, and cross-provider/model drift fail closed. Bounded + live progress, detailed events, same-session reply identity, + cancellation confirmation, and restart reattach are supported exactly + where Grok ACP supports them, with stale session/run/child/model/ + workspace identities failing closed. Event pages, text, counts, + cursors, timings, and diagnostics are capped; envelope/prompt bytes + stay evidence and do not enter driver results or transport + preflight/observe/cancel/reattach requests. Process-local P17 lane + risk may remain; the module does not claim durable P19/P21 state, + supervisor cutover, or live Grok ACP qualification. Coverage lives in + `r1-grok-acp-driver` and `r1-grok-acp-driver-adversarial` tests. +- **Closed P20 DSH ACPX provider driver for Muse Spark 1.2 Contributor and Ox + Alpha.** Additive `DshApxDriverV1` hard-binds provider `dsh` plus exactly the + two allowed DSH models and implements the accepted P17 preflight/launch/ + reconcile/cancel lifecycle against an injected bounded ACPX one-shot + transport port, inheriting every envelope, capability, transition, and denial + rule from the accepted contract with no parallel schema. ACPX provides no + authoritative prompt-sent acknowledgement: after spawn intent the posture + stays `dispatch_uncertain`, post-intent exceptions and loss are never + replayed, retried, or fallback-substituted, and only provably pre-spawn + failures may report `not_sent` under a two-attempt lane budget. Same-session + reply is unsupported: unresolved attention surfaces honestly and no + replacement prompt or session is started. Live progress, detailed events, + cancellation confirmation, and restart recovery read recorded ACPX evidence + through bounded cursor-monotonic pages; exact model/config/credential + identity and task/session correlation fail closed on drift; forged receipts + fail closed while genuine loss degrades to uncertainty. Events, records, + cursors, lanes, attempts, operations, clock readings, and diagnostics are + capped, and detail telemetry is content-free by construction. The module + claims no real-transport qualification, durable P19/P21 store, supervisor + cutover, or merge/PR authority; the exact port surface for later real DSH + Muse/Ox lifecycle conformance is recorded in + `docs/dsh-acpx-driver.md`. Coverage lives in `r1-dsh-acpx-driver` and + `r1-dsh-acpx-driver-adversarial` tests. +- **Closed P17 provider-driver envelope and capability contract.** Additive + `ProviderDriverV1` owns the preflight/launch/reconcile/cancel lifecycle + plus typed results, exact ChildEnvelopeV1 launch proof (text bytes and + raw lowercase 64-hex P03 digest; digest-only launches are denied), and + honest capability declaration through the accepted P05 13-field + `ProviderCapabilitiesV1` bridge rather than a parallel schema. + Driver-surface features for same-session-adjacent live progress, + reconcile-only restart reattach, cancellation, and detailed events fail + closed when unsupported, with no fallback or post-dispatch replay. + Process-local status transitions refuse duplicate dispatch, stale + envelope correlation, and capability-contradicting launch certainty. + Direct-JS inputs use the P05 descriptor-first closure; validated values + are detached and deeply frozen. The module claims no provider transport, + registry cutover, scheduler, or durable store. Coverage lives in + `r1-provider-driver` and `r1-provider-driver-adversarial` tests plus the + reusable `provider-driver-contract-suite` harness. + +- **Durable local run store and idempotent submission.** Additive + `run-store.mjs` persists one bounded canonical record per run in an + explicit caller-supplied existing private directory. The store fails + closed on symlink, non-directory, and unsafe ownership or mode + surfaces, uses strict no-follow opens, and never derives child paths + from untrusted strings. Records bind the accepted P06 run identity, + Git repository/base authority, initial dispatch provenance and + telemetry facts, and request idempotency key. Exact same key plus + canonical body returns the existing record without mutation; same + key with a different body, same run with a different body or key, + and mismatched protected identity fail closed with typed constant + errors. Creates use private same-directory temporary files, complete + writes, fsync of file and directory, and exclusive link/rename + without overwriting an authoritative record. Restore audits + canonical bytes and recomputes every accepted P06 digest, and + rejects hardlinked or non-regular files, malformed JSON, duplicate + or foreign entries, truncation, oversized records, excess entries, + and leftover temporary files without following them. Enumeration, + bytes, record counts, filename lengths, and diagnostics are bounded + and never echo record contents or credentials. Concurrent duplicate + submissions keep one authoritative mapping from run id and request + idempotency key to the identical stored record. There is no journal + or reducer, scheduler, provider driver, artifact store, workspace + provisioning, cleanup, MCP wiring, or protected-ref implementation. + Coverage lives in `r1-run-store` and `r1-run-store-adversarial` + tests. - **Protected identity and monotonic telemetry schemas.** Additive `protected-identity.mjs` / `protected-telemetry.mjs` close exact run, child, provider-run, workspace, and Git identities plus a content-free diff --git a/SECURITY.md b/SECURITY.md index 0e8e9ed..4ad931c 100644 --- a/SECURITY.md +++ b/SECURITY.md @@ -40,6 +40,9 @@ and local; sanitized bounded evidence is the model-facing projection.

Secret keys are written +to a bounded owner-only no-follow regular file under `XDG_RUNTIME_DIR` +(else the process temp dir), mode `0600`, directory `0700`. The service +command is always wrapped by `credential-handoff-loader.mjs`, including +Cursor Local which has no provider secrets of its own, so the worker is +never the manager-inherited leader. + +The loader opens the file with the same no-follow rules, applies the +values, unlinks the file (and best-effort the directory), then runs the +original command as a child with a closed service projection plus those +credentials. It does not spread `process.env`. Nested Grok and Cursor +Local ACP children receive that same closed projection through +`createAcpRuntime` / `closedProviderEnv`; ACPX does not start from +ambient `process.env`. The loader stays the service leader so +`KillMode=control-group` still reaches descendants. + +Cleanup unlinks any remaining handoff file after spawn failure, cancel, +terminal stop, or a later restart (a restart creates a new file).

There is no +// window in which a partial artifact exists under an authoritative name. +// - Exact same validated ref plus bytes is IDEMPOTENT: the loser of a race +// re-verifies the winner's stored state and returns an equal receipt +// marked created:false. Conflicting content at one location, the same +// digest with mismatched metadata, or any other competing publication +// fails closed with a typed content-free error and leaves the +// authoritative state untouched (a race loser rolls its own just-linked +// content back, but only after the platform proves the inode is ours). +// - Roots and parents use descriptor/no-follow discipline: the root must +// be an existing real owner-owned group/other-private directory opened +// O_NOFOLLOW|O_DIRECTORY|O_NONBLOCK and identity-bracketed by +// device/inode; every namespace and parent component is lstat-walked, +// created 0700 when missing, and re-proven after publication, so root, +// namespace, and parent swaps are rejected wherever the platform can +// prove them. +// +// Verification and audit stream content in fixed chunks solely to recompute +// length and digest - artifact bytes are never returned, echoed, or buffered +// whole.
