Problem and value

Related: #1129.

An annotated tag object can pass revision availability checks because Git peels it to a commit. Check the exact authored object type and reject non-commit revisions with repository-evidence/revision-not-commit; actual commit IDs remain accepted.

The maintainer accepted this bounded scope in the scope review. PR #1141 concerns relationship evidence; #1063 concerns Enterprise links; #1119 has no content change in this verifier. None enforces the exact revision object type.

Contributor review

• Problem origin: synthetic replay/code inspection of the linked public report; no production incident or real Agent generation benchmark is claimed.
• I reviewed the submitted changes and explanation, understand their impact, and can answer questions about them. Validation results and gaps are recorded below.

The accountable contributor explicitly confirmed personal review of this candidate, its explanation and visible results on 2026-10-29.

Stability impact

Shared repository evidence behavior. The change is bounded to the behavior described above. Test-value review selected observable content/URL/acceptance regressions rather than implementation snapshots: each new regression fails on the base and passes with this fix. Existing related coverage is reused. No separate simplify-codebase refactor was needed for this local correction; no speculative abstraction or configuration is added.

Tests run

Base: 847146aeb93b492592adb78dc220f57e4a8b4636 (dev). Original qualified candidate: 35aaa34556cff2d6d561740abb742f6cdba18009 (the same three correction files are retained in the updated candidate below).

Node 22.23.2, macOS arm64, zlib 1.3.1-e00f703:

• Base plus the new test: node --test test/repository-commit-object.test.mjs — fails, exposing the reported behavior.
• Candidate: npm run test:focus -- test/repository-commit-object.test.mjs test/repository-evidence.test.mjs — passes.
• npm test and npm run test:generated — pass.
• git diff --check — passes.
• Canonical bash scripts/build-zip.sh — passes; extracted ZIP smoke passes for the changed behavior.

These are fixed-input regressions and scoped core/generated checks. The local results above retain their original scope. No real-repository Agent generation benchmark is claimed. The current remote CI results are recorded below.

Generated artifacts

Regenerated archify.zip from the candidate source using the canonical Node/zlib toolchain. SHA-256: f8b4e7bf7c20b21a44b6c1e2d8df4339a248cf53c702ed7a64498f8ba23d3893. The extracted distribution was exercised; no release or deployment is requested by this PR.

Baseline full-suite limitation

The two generated-artifact checks described in #1147 also fail on the unchanged comparison base 847146aeb93b492592adb78dc220f57e4a8b4636. Their base reproductions and exact commands are recorded there. This correction does not regenerate unrelated Checkout/README assets; full upstream CI must not be inferred from the scoped passing checks above.

The separate baseline artifact repair is now #1150. #1151 addresses the independently reproduced Sequence fitting intermittence observed on #1147. #1150 is now merged and integrated into this contributor branch; the current result is recorded below. #1151 retains its separate validation and remains pending upstream.

Current review status

#1150 was merged by the maintainer into dev at 12b476771f81ad48da14946653dfbb8b5d347961 on 2026-10-29. This contributor branch now includes that base at 7456ce18ad6923d3d8f65fac644f1ce7cca30526. Its renderer/verifier change, regression test and ZIP are byte-for-byte identical to the personally reviewed candidate; the PR diff still contains only those three correction files. Existing focused/package evidence and personal review apply to those unchanged files.

CI run 40866334923 passed on this updated head: 19 successful jobs, no failures, and two expected deployment skips. Both full-regression shards and both browser shards executed and passed, together with Node 18/20/22/24, native Windows portability, package smoke on Linux/macOS/Windows, generated/ZIP freshness, website and artifact gates. The earlier failed run remains historical. Personal review covers the unchanged correction files; there are no unresolved review threads. This candidate meets the recorded requirements for review.

#1151 remains the separate Sequence fit correction; neither browser shard failed in this PR’s original run. The commit-object check retains its exact-object scope, with no fetching or normalization.

Current integration · 31 October

Head e9098454e6ad1e1e615b1c045a5c11b00c09f8e9 includes maintainer #1173 and dev 63c9263e84bd3993cab8e09b3d69888857858635. The original correction and test blobs remain byte-identical to 7456ce18ad6923d3d8f65fac644f1ce7cca30526; the existing personal confirmation retains that scope. The combined ZIP was regenerated and checked against the complete Skill tree.

Local qualification on tree 4c33474e1b144f1e0091d5ff5168b6fc83f6e9e1: generated/golden checks, 19 core smoke cases, 26 focused Sequence cases including Chrome, this PR's focused regression and clean-package smoke. The later integration of #1174 changes only the README GIF and receipt: the unchanged README/Gallery tests pass 15 cases with one native Windows-only local skip on final tree 174af6262d583027b5946766a3d9b84b4e73b4dd. All three input-artifact hashes match the separately recaptured #1174 animation. Source, tests and ZIP are unchanged by that second step. The earlier README freshness failure remains visible in the previous CI run.

CI41175242909 passed on this exact public head: 19 successful jobs, 2 expected skips, no failures. Both complete regression shards executed and passed. Both native Windows Node22/24 path-test gates executed and passed. Deployment jobs were skipped. The separate generated-media PR1174 remains Draft pending its own personal review; this update does not claim a new personal review of these mechanical commits.

Summary

The change checks the exact Git object type and rejects available non-commit revisions with repository-evidence/revision-not-commit. Commit IDs remain accepted. This changes compatibility for callers that use tag, tree, or blob object IDs as evidence revisions.

Reviewed base: 847146a; reviewed head: 35aaa34. The author reports passing focused tests, npm test, generated tests, and ZIP smoke checks. The reported 19-job CI pass and two expected skips came from later CI after another PR was integrated; they are not observed here as results at the reviewed head. These reports are a snapshot, not live CI status.

Repository revision verification now checks whether the exact pinned SHA identifies a commit object. It reports a diagnostic for other object types, including annotated tags. A test confirms that commit revisions pass and annotated-tag revisions fail. The live-proof manifest records updated artifact metadata.

Estimated code review effort: 2 (Simple) | ~10 minutes

Severity of issue fixed: Low

Possibly related issues

• [Bug]: Repository evidence accepts annotated tag object IDs as commit SHAs #1129: Reports that annotated tag object IDs pass repository evidence validation; this change rejects them.
• [提案]：Task_Checklist #1114: Requires task sources to use the shared validator and a fixed commit; this change affects that validator’s revision rule.
• Add Verifiable Source Evidence to Architecture Relationships #1132: Requires invalid revisions to produce diagnostics; this change strengthens revision validation but does not add relationship evidence.

Full details: Validation Evidence

Explanation

Evidence is sufficient for the evaluated range 63c9263..e909845. The diff changes verification from peeled ${revision}^{commit} resolution to git cat-file -t with repository-evidence/revision-not-commit. The added fixture accepts a real commit and rejects an annotated tag object. The author-reported focused, core, generated, package, and final-head CI checks cover the shared verifier and affected outputs; the verifier and test blobs remain unchanged from candidate 35aaa34 through the final head, so the focused behavior evidence is reusable. Observed checks confirm git diff --check, the live-proof manifest hashes, and the current GIF and artifact bytes. The author-reported ZIP hash belongs to the earlier candidate; the final head contains a regenerated ZIP, whose archived verifier source matches the current source. No material validation claim remains unsupported.

Full details: Contribution Scope

Explanation

The core fix is focused and documented: the PR links issue #1129, records maintainer scope acceptance, preserves commit-SHA acceptance, rejects non-commit objects with repository-evidence/revision-not-commit, and adds a regression test. However, the reviewed diff also changes docs/assets/archify-live-proof.gif and its manifest. Commit 355ea380... identifies that change as a README animation refresh after Sequence header centering. This is unrelated to repository-evidence verification. The available Generated artifacts section names only archify.zip, so the PR does not explain this extra delivery slice.

Resolution

Remove the unrelated README animation GIF and manifest changes, or split them into a separate PR. Retain the verifier change, regression test, and necessary ZIP update. Then update the Generated artifacts section to list every remaining generated file and its source, and provide the complete latest PR description if the omitted review-status text contains a scope decision for the animation refresh.

[BlueboxC]

The bounded scope is accepted, and I have personally reviewed this candidate, its explanation and results. The description now records that confirmation.

This stays Draft because CI run 40764441529 is still red on unchanged head 35aaa34556cff2d6d561740abb742f6cdba18009: full-regression (2) exposes the two baseline stale-artifact failures repaired separately in #1150, and test (22) reports that failure. Both browser shards and Windows portability jobs passed. #1150 remains unmerged; #1151 is the separate Sequence fit repair for the agreed integration sequence. Integrate the separate repairs first, then validate the resulting candidate. The exact commit-object check retains its original scope and does not fetch or normalize revisions.

Please review the code while the external CI dependency remains open.

Assert the exact diagnostic code for the annotated tag.

The current assertion checks only the error message. Capture the error and assert repository-evidence/revision-not-commit so this regression test protects the diagnostic contract.

Suggested fix

-  assert.throws(()=>verifyRepositoryEvidence('architecture',data.diagram,data.root),/commit/i);
+  const error=assert.throws(()=>verifyRepositoryEvidence('architecture',data.diagram,data.root),/commit/i);
+  assert.equal(error.archifyDiagnostics[0].code,'repository-evidence/revision-not-commit');
