PR Review Summary
Status: Request Changes
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Request Changes
- Rationale: The ticket premise is valid and the diff-aware direction is the right substrate, so this is not Drop+Supersede. The remaining issues are bounded implementation/test gaps in the new per-commit git-diff boundary; they should be fixed before this guard ships.
Peer-Review Opening: This is the right follow-up to the #12608 first-touch tax. The important shape is there: per-commit mode stops taxing legacy refs, while sweep mode still catches existing debt. The two blockers below are about making the guard safe and proving the fallback path at the boundary it actually uses.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: #12609 body and Contract Ledger; changed-file list; current
devsource forbuildScripts/util/check-ticket-archaeology.mjs;package.jsonlint-staged wiring; current PR body/checks; exact-head commit log; focused unit-test skill guidance; local checked-out PR headd5be03ca8; CLI probes for per-commit and no-args modes. - Expected Solution Shape: A correct fix should scope the lint-staged path to staged-added lines while preserving full-file no-args sweep behavior. It must not build shell commands from staged filenames; filenames are part of the hook input surface. Test isolation should cover the parsing/filtering helpers and the actual fallback branch that turns git-unavailable into a full-file scan.
- Patch Verdict: Partial match. The happy path and sweep separation work, but
stagedAddedLines()shells out through an interpolated filename string, and the no-git fallback is only indirectly represented byfilterToAddedLines(null), not exercised at the helper/CLI boundary named in the ticket.

🔬 Depth Floor
Challenge: The new implementation correctly avoids first-touch legacy debt, but it moves staged filenames into a shell command at stagedAddedLines(). Since lint-staged supplies file paths, the safer boundary is argv-based git execution (spawnSync / execFileSync) rather than string interpolation. This is exactly the kind of guard where the implementation should not add a new path-escaping footgun.
Rhetorical-Drift Audit (per guide §7.4):
- PR description: framing matches the intended diff-aware behavior.
- Anchor & Echo summaries: JSDoc describes the helper roles precisely.
-
[RETROSPECTIVE]tag: N/A — no retrospective tag in PR body. - Linked anchors: #12609 and #12608 establish the stated friction path.
Findings: Pass on framing; implementation blockers are listed below.
🧠 Graph Ingestion Notes
[KB_GAP]: None surfaced. The ticket and local source were sufficient authority for the hook contract.[TOOLING_GAP]: #12609 itself is valid friction→gold: full-file lint-staged scanning forced a documented--no-verifyon#12608despite a clean diff.[RETROSPECTIVE]: Diff-aware per-commit scanning is the right split when a separate full-file sweep mode already exists; the guard can preserve anti-archaeology enforcement without making every feature PR clean historical comments.
🎯 Close-Target Audit
- Close-targets identified: #12609
- #12609 confirmed not
epic-labeled. - Branch commit message targets #12609 only.
Findings: Pass.
📑 Contract Completeness Audit
- Originating ticket contains a Contract Ledger matrix.
- Implemented PR diff matches the Contract Ledger exactly.
Findings: Required Action. The ledger requires the args path to fall back to full-file scan when git cannot be consulted. Mechanically, filterToAddedLines(null) is tested, but the function that actually consults git (stagedAddedLines) is private and untested at the failure boundary; the current tests do not prove a git failure/no-HEAD path returns null and therefore preserves the full-file fallback.
🪜 Evidence Audit
- PR body contains an
Evidence:declaration line. - Evidence class is appropriate for the build-hook logic.
- Evidence fully proves the close-target fallback ACs.
Findings: Required Action. L2 focused tests prove hunk parsing and filter behavior, and local CLI probes prove current per-commit/sweep distinction. They do not directly exercise the no-git/full-file fallback path named in #12609's ACs and Contract Ledger.
N/A Audits — 📡
N/A across listed dimensions: no ai/mcp/server/*/openapi.yaml tool descriptions are modified.
Conditional Audit Triggers
CI / Security Checks Audit
- Findings: CI is green now:
gh pr checks 12611reports Analyze, CodeQL, integration-unified, lint-pr-body, and unit all passing. Security-sensitive command construction still has a local implementation finding:stagedAddedLines()usesexecSync(git diff ... "${file}"), so the staged filename is interpreted by the shell instead of passed as a literal argv element.
🔗 Cross-Skill Integration Audit
- Existing pre-commit convention remains in
package.jsonlint-staged. - No skill file needs to invoke a new pattern; this is a hook behavior change, not a new lifecycle rule.
- Full-file sweep remains available for deliberate cleanup.
Findings: Pass after the implementation/test fixes below.
🧪 Test-Execution & Location Audit
- Branch checked out locally via
checkout_pull_requestatd5be03ca87c007f21c9184130bb77bfa53448d35. - Canonical Location: tests remain under
test/playwright/unit/ai/buildScripts/util/, matching right-hemisphere build-script coverage. - Ran the specific changed test file.
- Ran focused CLI probes for per-commit and no-args sweep behavior.
Findings: Tests pass, but coverage gap remains for the fallback path.

📋 Required Actions
To proceed with merging, please address the following:
- Replace the shell-string
execSynccall instagedAddedLines()with an argv-based git invocation (spawnSyncorexecFileSync) so staged filenames are passed literally. Preserve the existing safe fallback: any git failure returnsnull, never a blind pass. - Add direct coverage for the git-unavailable/no-HEAD fallback at the actual diff-fetch boundary, not only
filterToAddedLines(null). The test should prove the args path falls back to full-file hits when the diff runner fails.
📊 Evaluation Metrics
[ARCH_ALIGNMENT]: 88 - 12 points deducted because the diff-aware/sweep split aligns with #12609, but shell-string command construction is a boundary mismatch for a hook consuming staged filenames.[CONTENT_COMPLETENESS]: 90 - 10 points deducted because PR/ticket documentation is thorough, but the stated no-git fallback proof is stronger in prose than in tests.[EXECUTION_QUALITY]: 78 - 22 points deducted because focused tests and CI pass, but the new command boundary is unsafe and a required fallback branch lacks direct coverage.[PRODUCTIVITY]: 84 - 16 points deducted because the main first-touch-tax problem is mostly solved, but the guard cannot merge until the command boundary and fallback proof are tightened.[IMPACT]: 62 - This is a meaningful build/contributor-experience fix for every agent touching legacy.mjsfiles, but it is not a runtime framework feature.[COMPLEXITY]: 45 - Moderate: two-file patch with small helper logic, but it sits on a commit gate where path handling and fallback behavior matter.[EFFORT_PROFILE]: Quick Win - The fix should be bounded to command invocation plus one focused fallback test; the underlying architecture does not need reshaping.
The premise is solid. Tighten the path execution boundary and prove the fallback branch, and this should be a short re-review.
PR Review Summary
Status: Approved
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Approve
- Rationale: The patch implements #12609's recommended diff-aware hook shape while preserving the full-file sweep path. Cycle-1 required actions are resolved on exact head
c80e5a3b6: staged filenames now cross the command boundary through argv-basedspawnSync, and the git-failure fallback boundary is unit-tested directly.
Peer-Review Opening: Cycle-2 re-review complete. The shell-boundary and fallback-proof gaps from my prior review are resolved without broadening the PR beyond the hook contract.
🧭 Patch-Blind Premise Snapshot

buildScripts/util/check-ticket-archaeology.mjs, focused spec file, live #12609 label state, CI status onc80e5a3b6. - Expected Solution Shape: The lint-staged path should block only newly-added durable ticket refs, never untouched legacy refs; no-args sweep must remain full-file; git-unavailable/no-HEAD must fall back to full-file rather than blind-pass; staged file names must not be interpolated into a shell string.
- Patch Verdict: Matches the expected shape.

Resolves #12609
Makes the
check-ticket-archaeologypre-commit hook diff-aware in its lint-staged (per-commit) path: it scans only the lines a commit actually adds, so a clean commit is never blocked by pre-existing legacy ticket-refs in untouched regions of a file it happens to touch. New refs in the staged diff still hard-block; the no-args sweep keeps full-file scanning.This removes the first-touch tax that forced a documented
--no-verifyon #12608 (theMailboxService.spec.mjscarried 19 legacy refs, zero from that diff).Evidence: L2 (focused unit coverage — hunk-parsing / filter / end-to-end — plus a real-file proof on
check-branch-discipline.mjs) → L2 required (build-tooling logic, unit-verifiable). No residuals.How
parseAddedLines(diffOutput)— pure: parsesgit diff --unified=0hunk headers (@@ -old +new @@) → Set of new-side added line numbers (-lines do not advance the counter;--unified=0has no context lines).filterToAddedLines(hits, addedLines)— pure: keepsfindTicketRefshits whose line is in the added set;null→ returns all (the full-file fallback).stagedAddedLines(file, gitRoot, runGitDiff?)— runs git via argv-basedspawnSync(no shell string built from the staged filename); empty diff → empty set (nothing added), git failure (spawn error / non-zero status) →null(full-file fallback, never a blind pass). The runner is injectable so the fallback boundary is unit-testable.main()— per-commit mode (argvFilespresent) scopes hits to added lines; the no-args sweep (collectDefaultFiles) keeps full-file scanning.
