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.

Task 7.3 brief

Requirements 3.5, 4.1, 4.2 and 7.1–7.3; design: Delta and Actionability Policy, Push runner and existing endpoint/redaction integration. Explicit endpoint/model only, one remaining deadline, no-model identity preserved. Assistance selects existing admitted witness indices and cannot contribute prose, evidence, a rung or a finding. Record prompt/model/usage/cost provenance and retain deterministic fallback. Verify misleading/delayed replies, outbound redaction, no unadmitted input, and an actual loopback HTTP request through the existing endpoint adapter. No external provider used.

Status Report

• STATUS: READY_FOR_REVIEW
• TASK: 7.3
• RED_PHASE_OUTPUT: /tmp/group7-3-red.log: six failures with the feature OFF, default no-model identity passes. ON: seven passed; switch removed. Final assistance/report suite: 27 passed, including endpoint receipts, delayed/misleading replies, redaction, dotenv isolation and witness/location binding.
• TESTS_RUN: full suite 1295 passed, 9 skipped in 149.70s; final 27 focused tests validate the subsequent renderer binding refinement. Ruff, formatting (254 files), mypy (115 source files), compileall and diff checks pass.
• CONCERNS: cost is explicitly unknown when receipt/pricing is missing; cancelled remote requests may still incur provider cost. All provider tests use synthetic clients or loopback HTTP. No normal capability enabled.

Review Verdict

• VERDICT: APPROVED
• TASK: 7.3
• MECHANICAL_RESULTS: actual code/diff reviewed against requirements 3.5, 4.1, 4.2 and 7.1–7.3. Regression/static checks pass. No new placeholders, hardcoded credentials or scope/ranking/admission changes. Synthetic key strings occur only in redaction controls.
• FINDINGS: repaired implicit pre-deadline dotenv loading; explicit configuration reuses the existing loader with dotenv disabled. Model-selected witness location and change explanation remain bound to that witness's admitted disposition. Incomplete usage is never priced as zero. Unknown/extra model response fields cannot create claims.
• RED phase: VERIFIED.
• SUMMARY: Optional assistance is bounded presentation selection over existing admitted evidence, with deterministic fallback.

Verification Result

• STATUS: VERIFIED
• CLAIM_TYPE: TASK
• CLAIM: Task 7.3 and group 7 integration are implemented and locally verified.
• EVIDENCE: /tmp/group7-final-suite.log (1295 passed, 9 skipped), /tmp/group7-3-final-assistance-report.log (27 passed), /tmp/group7-3-final-focused.log (34 passed). Detection gate 44/47, FP 0/44; map gate PASS; pair gate 3/3, labeled 28/28, zero fix leaks. Ruff, mypy, formatting, compileall and shell syntax pass. Docker build exit 0; image sha256:af5b896b406fe98acb3d00bb2180a7549febd6dd285f0b63087538118e52e1f4. Network-disabled packaged CLI help and real empty Git-stdin transaction both exit 0 as UID 1000; readable 1085-byte artifact records not_applicable, model disabled, no scans.
• GAPS: Packaged smoke verifies liveness and input/report integration, not detection performance or alert eligibility. Main-context review fallback is not independent review. Group 8 remains pending and rollout remains NO-GO.

Current specification status

Requirements, design and tasks remain approved. Implementation: 23/27 executable subtasks complete (85.2%); groups 1–7 complete, group 8 has four pending tasks. No new implementation blocker. Upstream contributor-scan contracts and existing ranker remain unchanged. Revalidate multi-ref deadline/cancellation, hook failures and model fallback in group 8.1, representative changed-code performance in 8.2, independent capability admission in 8.3, and packaged end-to-end usefulness in 8.4. The accepted rollout gates are unchanged; zero enabled capabilities cannot satisfy them.
