Group 8 implementation and qualification

The maintainer authorized group 8 on 2026-09-13. Fresh agent dispatch failed with agent thread limit reached; the explicit manual Kiro fallback applies. Reviews are main-context reviews, not independent reviewer evidence. Joint rollout gates remain unchanged; implementation progress does not imply capability eligibility.

Task 8.1 brief

Requirements 1.1–1.4, 2.2, 2.3, 4.2, 4.4, 5.2, 5.5, 7.1, 7.4 and 8.2; design: Snapshot Adapter, Cache/Engine Boundary, Push runner and Result/Hook Adapter. Combine immutable non-HEAD/tag/force/new-branch/deletion updates, unusual paths, external boundaries, physical vendor exclusion, census failure and interrupted report publication. Use production transaction/backend seams; preserve source/index/refs, truthful scope and prior artifacts, and prove worker cleanup. Tests only: no production behavior or feature toggle introduced. Existing focused suites retain the full cache, missing-base, hook-exit and ordinary-scan regressions.

Status Report

• STATUS: READY_FOR_REVIEW
• TASK: 8.1
• RED_PHASE_OUTPUT: N/A: tests-only integration coverage; no production behavior changed.
• TESTS_RUN: Three added combined controls pass. Full suite 1299 passed, 9 skipped in 117.83s; ruff, formatting and mypy pass.

Review Verdict

• VERDICT: APPROVED
• TASK: 8.1
• MECHANICAL_RESULTS: actual new tests inspected, full regression suite passes, no placeholders or secrets; test-only integration boundary maintained.
• FINDINGS: mixed push control verifies all three exact comparisons and four dispositions, readable snapshot bytes, live state preservation and external-content exclusion. Failed census control inspects physically filtered source before returning missing answers. Interrupted writer control checks previous bytes and absence of its process PID.
• SUMMARY: Combined failures remain explicit and do not masquerade as clean checks.

Verification Result

• STATUS: VERIFIED
• CLAIM_TYPE: TASK
• CLAIM: Task 8.1 integration regression coverage delivered.
• EVIDENCE: /tmp/group8-1-focused.log: 3 passed; /tmp/group8-1-full.log: 1299 passed, 9 skipped; static checks exit 0.
• GAPS: These controlled failures do not qualify real detector capabilities or representative latency.

Task 8.2 brief

Requirements 4.1, 4.2, 6.2, 6.3, 6.5 and 7.3; evaluation/runtime integration boundary. Freeze full pinned NodeGoat histories before measuring: three distinct function edits, dependency edits, configuration edits, growth histories and multi-ref transactions, plus three identical-comparison and three uncached controls. Each edit repetition has a distinct tree, avoiding accidental identical-tip reuse. Retain all 21 transactions, exact source byte receipt, installed semantics, hardware, selected/deferred counts, expected target checks, stage process receipts and whole CLI elapsed time. A separate 600-second priming run is diagnostic and cannot replace a 30-second gate sample.

Nearest-rank p50/p95 include timeout durations and report small sample counts explicitly. A missing artifact or abnormal CLI exit is an instrument error, never a clean result. Source/vendor/context/coverage gaps remain gaps. NodeGoat remains development data; this runtime experiment cannot qualify independent alert precision or broad production performance. Engine lifecycle costs route to contributor-scan's runtime follow-up.

Task 8.2 measured outcome

Packaged image af5b896b406fe98acb3d00bb2180a7549febd6dd285f0b63087538118e52e1f4, network disabled, UID 1000, 3 GiB memory limit; CPU/affinity and installed identities are in benchmarks/measurements/2026-09-13-nodegoat-feasibility.json. All 21 artifacts match the frozen core/facts/queries/policy/runtime/semantics. All 24 declared target checks remain incomplete. Priming took 224.47 seconds and did not qualify graph/answer reuse; subsequent cache attempts establish discovery reuse only.

Workload	n	p50 seconds	p95 seconds	Timeouts	Completed target checks
Identical comparison	3	30.635	30.644	3	0/3
Distinct function edits	3	30.611	30.663	3	0/3
Dependency edits	3	30.627	30.712	3	0/3
Configuration edits	3	30.606	30.728	3	0/3
Cold	3	30.609	30.631	3	0/3
Growth	3	30.894	30.912	3	0/3
Multi-ref	3	30.652	30.692	3	0/6

These are observed timings of the declared attempts, not proof of a qualified warm graph path. All timeouts remain in the population. Cancellation/reporting meets the 2-second allowance in these samples; latency and completion do not meet the joint gate. Runtime and rollout verdict: NO-GO. The n=3 quantiles do not establish multi-project production performance. The full 116-file receipt bundle is 1,254,241 bytes compressed, SHA-256 3174bfc0bd39e10b685d06d8bc28ab39450368f1a441e64bbb5a27a256bf13c6. Decompression was compared to every original file. Both measured instrument bytes and the original frozen scorecard are retained; later scorer hardening preserves the measurements and adds missing-workload and multi-ref-denominator checks.

Owner routing: ../contributor-scan/pre-push-runtime-followup.md separates raw named census reconciliation from frontend/overlay/JVM/query lifecycle optimization. Do not retune the ranker or weaken the population/gates to compensate.

Status Report

• STATUS: READY_FOR_REVIEW
• TASK: 8.2
• RED_PHASE_OUTPUT: /tmp/group8-2-red.log (missing scorer) and /tmp/group8-2-flag-off.log (disabled scorer). ON passed; switch removed, seven final scorer tests passed.
• TESTS_RUN: full suite 1306 passed, 9 skipped in 117.63s; ruff, formatting, mypy and diff checks pass. Frozen packaged measurement completed with exit 1 and full NO-GO scorecard, no missing artifacts or abnormal CLI exits.

Review Verdict

• VERDICT: APPROVED
• TASK: 8.2
• MECHANICAL_RESULTS: actual harness, fixtures, scorecard and receipt bundle reviewed. Input bytes/pins, distinct edit histories, all 21 runs, stage exits, fixed target denominators and source/runtime identity checks retained. Invalid numbers, duplicate/unplanned rows, missing workload classes and missing cases cannot qualify runtime. No production/ranker/fact changes.
• FINDINGS: Initial warm-graph precondition failed; the report explicitly limits reuse claims. The unchanged runtime gates fail. Engine lifecycle and named census follow-up routed to contributor-scan.
• RED phase: VERIFIED.
• SUMMARY: Reproducible runtime evaluation is complete with a measured NO-GO result.

Verification Result

• STATUS: VERIFIED
• CLAIM_TYPE: TASK
• CLAIM: Task 8.2 completed its prescribed measurement and owner routing; rollout remains NO-GO.
• EVIDENCE: Versioned scorecard and 116-file verified bundle; seven scorer controls and full regression suite pass.
• GAPS: No qualified warm graph path or independent capability eligibility established. These failed gates cannot authorize rollout.
