Group 7 implementation and verification

The maintainer authorized all of group 7 on 2026-09-13. Fresh agent dispatch failed with agent thread limit reached; kiro-impl's explicit manual fallback applies. Reviews here are main-context reviews, not independent reviewer evidence. Rollout remains NO-GO and the default capability registry remains empty.

Task 7.1 brief

Requirements 1.1, 1.3, 1.4, 4.1, 5.1–5.5 and 7.1; design: Snapshot Adapter, Push runner, Result and Hook Adapter. Consume every Git update and remote identity, resolve exact comparisons using the existing adapter, share one absolute budget, retain independent finding/coverage/enforcement statuses and all comparison evidence. Verify real stdin delivery, immutable readable snapshots, deduplication, missing bases, deletions, no work, policy combinations and deadline ownership.

Status Report

• STATUS: READY_FOR_REVIEW
• TASK: 7.1
• RED_PHASE_OUTPUT: /tmp/group7-1-red.log: four failures with the interface switch OFF. ON: 37 focused tests passed; switch removed, final focused run: 29 passed (including 11 transaction controls).
• TESTS_RUN: full suite 1274 passed, 9 skipped in 109.09s; final targeted tests cover the subsequently added five policy combinations and retained resolved identity on preparation failure. Ruff and mypy pass.
• CONCERNS: synthetic admission controls prove enforcement, not detector eligibility. No capability enabled.

Review Verdict

• VERDICT: APPROVED
• TASK: 7.1
• MECHANICAL_RESULTS: actual diff reviewed; full suite and final targeted checks pass; no new placeholders or credentials; boundary restricted to CLI, push runner and report.
• FINDINGS: fixed child stdin closure by duplicating Git's descriptor before forking; remote URL is hashed rather than storing possible credentials; unresolved comparison identity survives preparation failure.
• RED phase: VERIFIED.
• SUMMARY: One transaction retains every resolved ref and completed scan without resetting the analysis deadline.

Verification Result

• STATUS: VERIFIED
• CLAIM_TYPE: TASK
• CLAIM: Task 7.1 interface and policy integration implemented.
• EVIDENCE: /tmp/group7-1-full.log, /tmp/group7-1-final-focused.log; ruff, mypy and diff checks exit 0.
• GAPS: Representative multi-ref performance and real capability admission remain group 8 work.

Task 7.2 brief

Requirements 1.2, 5.3, 5.4 and 7.4; design: Result and Hook Adapter. Deliver executable opt-in integration and non-overwriting installation, preserve the configured hook path, explicitly chain a prior hook with its exact input/arguments, retain rejection, and document guarded removal. The existing hook's runtime remains its own behavior; input retention and Safety Net analysis share one deadline. Verify with disposable repositories and a local bare remote, never this project's hooks.

Debug Report

• ROOT_CAUSE: git rev-parse --path-format=absolute --git-path hooks/pre-push canonicalizes the final symlink, so even O_EXCL on the returned name creates its target. Initial attribution to shell noclobber was not supported by the subsequent test.
• CATEGORY: LOGIC_ERROR
• FIX_PLAN: Resolve only hooks, append the literal pre-push basename, and create with O_EXCL/O_NOFOLLOW.
• VERIFICATION: Dangling-symlink regression passes; target remains absent.
• NEXT_ACTION: RETRY_TASK
• CONFIDENCE: HIGH
• NOTES: Git documents absolute output as canonical: https://git-scm.com/docs/git-rev-parse/2.33.0.html . Guarded removal instructions use directory-only resolution too.

Status Report

• STATUS: READY_FOR_REVIEW
• TASK: 7.2
• RED_PHASE_OUTPUT: /tmp/group7-2-red.log (missing integration); /tmp/group7-2-flag-off.log (two failures with chaining OFF). ON: three passed; switch removed, final 16 hook/interface tests passed.
• TESTS_RUN: full regression 1282 passed, 9 skipped in 119.95s; final 16 focused tests include subsequently added exact-exit and symlink controls. Ruff, formatting, mypy, shell syntax, CLI help and diff checks pass.
• CONCERNS: input-retention failure stops the integration because a prior hook cannot safely receive partial input. Prior hook runtime remains separate from analysis.

Review Verdict

• VERDICT: APPROVED
• TASK: 7.2
• MECHANICAL_RESULTS: actual diff and installation/removal recipes reviewed; disposable remote accepts/rejects correctly; original stdin bytes/arguments and exact nonzero exit preserved; source/index/ref state and core.hooksPath preserved; no placeholders or secrets; task boundary maintained.
• FINDINGS: final-path canonicalization issue repaired and regression tested. Installation is explicit and does not overwrite existing hooks or symlink targets.
• RED phase: VERIFIED.
• SUMMARY: Opt-in integration preserves prior hook behavior and supports guarded restoration.

Verification Result

• STATUS: VERIFIED
• CLAIM_TYPE: TASK
• CLAIM: Task 7.2 non-destructive hook integration delivered.
• EVIDENCE: /tmp/group7-2-full.log, /tmp/group7-2-final-focused.log; static checks and shell/CLI smoke exit 0.
• GAPS: No hook installed in this project's actual repository; rollout remains NO-GO.
