Codex native V2 reviews now bind the parent activity, child identity and first completed review to the exact codex-native-v2/0.162.0-alpha.2 profile. Invalid completion, steering, stale associations and linked transcript paths refuse admission. The existing V1 boundary remains intact, and large verification contexts retain bounded result space through immutable references.

This completes integration with the merged #918 and #944 work. It corrects native fixture path aliases, removes a shadowed digest validator, aligns hook contract tests, and adds the missing large-context regressions. Valid Unicode stays within its JSONL record, and unrelated relative-target collaboration no longer requires a review transcript. Active protected reviews still refuse ambiguous steering. The protected candidate verifier prerequisite landed in #946. Canonical Python and generated host copies remain identical.

The workflow atlas now validates actual bytes from immutable Git objects, retains exact explicit blob pins and historical source comparisons, and binds the reviewed V2 owners to integration commit 25980c292b529fca90c39f5f26d69a1c0674de44. Each implicit source needs one Git lookup, isolated from inherited Git repository and object selectors. The two-repository regression proves foreign objects cannot satisfy the selected repository. Both lookups disable replacement refs; a regression verifies that replacements cannot substitute reviewed blobs or lens trees. Package versions are synchronized at ca 2.25.5, ca-codex 0.16.5 and ca-pi 0.17.6.

Validation:

  • Focused Python native V2, digest, linked-ancestor and large-context regressions pass. The two capacity tests detect their deliberate faults. Two additional runtime regressions are RED then GREEN; all 12 affected V2/V1 contract tests pass, with independent malformed-record and active-steering refusal checks.
  • Version identity and cold startup pass: 22 descriptor tests and 468 cold-install assertions. Adapter constants, package manifests and provenance claims use the same existing release versions. The unchanged eight-check provenance suite passes after refreshing two manifest hashes.
  • Native V2 Go tests and go vet pass. Hook inventory, adapter, package, generated-source parity and static candidate checks pass.
  • Final atlas tests, coverage, generation and typecheck: 55/55 focused tests pass; whole atlas.ts coverage is 100% lines and 86.44% branches; generation and typecheck pass with unchanged test deadlines.
  • Independent auth, security and coverage reviews pass within their declared scope. Staged secret scanning passes.
  • Exact-head hosted CI passed: all six native platforms, all 18 cold packages, browser qualification and merge readiness. Native Go statement coverage is 82.86% against the 70% floor. The full site workflow also passed.

Base: 216e1bc481e23c822ff6a8709bcd3c20e14d0646. Head: f32a48f1afa2a950b6d632b23e3ef91444826190. Use a merge commit to retain the atlas's immutable reviewed source commit. The installed ADR ancestry verifier is rechecked against the final base and head; the atlas source identity additionally requires retaining this branch history.

The changes retain shared ownership under ADR-0011 and the structured evidence boundaries in ADR-0037. Exact-profile admission preserves the existing security and reliability contract. Local fixtures and hosted CI do not establish installed-host qualification; no actual project state was migrated. Release and deployment verification are recorded separately after the existing automation runs.

Require the installed V2 runtime profile and correlate linked transcript
activity with the exact parent, child, turn and tool call before a review
can qualify. Retain bounded contexts and completion timeouts so inherited
review cohorts keep their validated behavior.

CHANGELOG: Reject stale, unlinked or steered Codex V2 review evidence while
preserving bounded completion review behavior.

The authority adapter adds Codex 0.162.0-alpha.2 native V2 review support and stores large verification contexts by reference. The Atlas source check now validates reviewed content against Git objects from the selected repository.

Changes

Codex Native V2 Review

Layer / File(s) Summary
Native V2 observation contract
core/artifacts/internal/observation/contract.go, core/artifacts/internal/observation/native_v2_test.go
The observation contract accepts the pinned V2 profile and checks launch, activity, child metadata, digest, and timing bindings. Tests cover valid receipts and invalid mutations.
Bounded verification-context storage
core/pysrc/_artifactauthoritylib.py, .github/scripts/test_artifact_authority_adapter.py
Verification contexts can be stored as frozen references with bounded state, validated command bindings, safe reads, and lifecycle reserve checks. Tests cover rehydration and rejection limits.
Native V2 launch and lifecycle
core/pysrc/_artifactauthoritylib.py, core/pysrc/_artifactlib.py, core/pysrc/artifact-authority.py
The adapter selects the V2 spawn tool and binds launch evidence to parent and child transcripts. It correlates lifecycle events and rejects mismatched or steering activity.
Lifecycle and publication validation
.github/scripts/test_artifact_authority_adapter.py, core/artifacts/internal/operations/native_v2_review_test.go
Tests cover lifecycle event orders, invalid evidence, capture and publication, freshness, and evidence drift.
Hook qualification and release integration
plugins/ca-codex/hooks/hooks.json, .github/scripts/*codex*, core/surface/includes/artifacts.md, docs/hooks.md, CHANGELOG.md, README.md, package.json, plugins/ca-codex/*, plugins/ca-pi/*, plugins/ca/.claude-plugin/plugin.json, .codearbiter/*, core/pysrc/hostapi.py
Codex hook matchers and timeouts, profile instructions, versions, release notes, and provenance records are updated. Pi release notes state that Pi review authority remains unsupported.

Atlas Reviewed Source Pins

Layer / File(s) Summary
Reviewed Git-object validation
site/scripts/execution-maps/atlas.ts, site/scripts/execution-maps/atlas.test.ts, site/scripts/execution-maps/atlas-changelog.test.ts
Atlas retrieves reviewed source blobs from Git. Tests cover explicit pins, malformed IDs, missing objects, symlink paths, repository selection, and changelog history.
Atlas revalidation and review record
site/scripts/execution-maps/atlas-revalidation.test.ts, site/WORKFLOW-ATLAS.md
Revalidation tests check reviewed blobs and product inputs. The workflow atlas records the native V2 compatibility review.

Integrate current main while retaining exact native parent/child activity
bindings. Repair canonical temporary fixtures, duplicate digest validation,
hook contracts and verification-context capacity proof. Keep immutable atlas
source checks bound to actual Git blob bytes and preserve all release history.

The atlas source revision is bound in the immediate follow-up commit so the
reference names this real integrated source. Exact-head hosted checks still
gate the completed branch and merge.

CHANGELOG: Bind Codex native V2 evidence and bounded verification contexts.
Bring the separately verified trusted checker prerequisite into PR945's
ancestry. Both checker files already match, so this merge changes no files.
Keep historical source comparisons while tying the current atlas to the
retained integration commit. Resolve each immutable source with one Git blob
lookup and share the validated atlas fixture across historical comparisons.
This avoids repeated process startup without changing source checks or test
time limits.

CHANGELOG: Keep workflow maps bound to the reviewed native V2 contract.

updated hash.

Review comments at @core/pysrc/_artifactauthoritylib.py:
- Line 3024: Update the suffix record iteration in `_codex_v2_activity` to split
the bytes on newline characters only, then decode each complete record as UTF-8
before parsing it with `json.loads`. Preserve the existing strict JSON parsing
behavior and rely on the required trailing newline to exclude the final empty
element.
- Around line 3405-3410: In _codex_native_steering, defer resolving a relative
target’s caller path until a registered V2 request in the same session is
LAUNCHING or RUNNING; do not let transcript errors block unrelated steering.
Resolve the path once for that request, and treat an AuthorityError as a
possible match so the authority check still refuses fail-closed.

Review comments at @site/scripts/execution-maps/atlas.ts:
- Around line 63-64: Update the Git subprocess calls in the reviewed-blob check
and loadAtlas to remove repository-location variables such as GIT_DIR,
GIT_WORK_TREE, GIT_INDEX_FILE, and GIT_OBJECT_DIRECTORY from the inherited
environment; apply the same isolation to tests that spawn Git for temporary
repositories. Add a timeout to the cat-file call and include the underlying
failure cause in its error instead of hiding it.

Preserve valid Unicode inside LF-delimited activity records and apply relative
steering checks only to active authority reviews in the caller's session.
Protected reviews still refuse when their target identity cannot be resolved.

Align adapter identities and provenance claims with the existing release
versions so strict root validation accepts the matching packaged manifests.

CHANGELOG: Preserve valid native review activity and unrelated collaboration.
Resolve reviewed objects in the selected repository even when the caller has
Git repository selectors in its environment. Retain normal Git configuration.
Bind the final V2 authority corrections to their immutable source commit while
preserving the original atlas links, geometry and historical assertions.

CHANGELOG: Keep atlas evidence bound to the reviewed repository and source.
