LLM ranking is a later experiment, not a prerequisite. If realistic changed-unit rebuilds cannot
meet the deadline/coverage gates, keep the hook experimental and revisit the graph strategy with
measurements; do not solve the miss by silently shrinking context or lowering alert standards.
### Group 7 integration decisions
The Git interface produces one aggregate report, retaining all resolved updates and
per-comparison change contexts. Deletions/no-work are not applicable; unresolved
updates remain gaps. The hook installer resolves only the effective hook directory
before exclusively creating the final filename, so final symlinks cannot redirect an
installation. Explicit prior hooks retain their original input, arguments and exit
behavior; their own runtime is separate from the Safety Net analysis deadline.
Optional model assistance is presentation-only witness selection after admission.
Only an existing admitted witness index can be selected. No generated prose becomes
an alert, and no model response changes scope, evidence strength, novelty, admission
or enforcement. A model/prompt-specific response is not cached; deterministic analysis
artifacts still use their existing semantic identities. Configuration, prompt
preparation and HTTP calls share the transaction deadline. Pre-push never implicitly
loads the working tree's `.env`; explicit model configuration uses the existing loader
with that behavior disabled. Unknown price or missing usage is an unknown cost, not zero.

- CLAIM: Task 7.2 non-destructive hook integration delivered.

- 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.

Neither installation nor removal modifies source, the index, refs, or hook-path
configuration. Keep any prior hook backup until restoration is confirmed.
Optional witness selection is enabled only with `--model-config /absolute/models.toml`.
Use the existing `[models]` settings, with an explicit model and endpoint:
```toml
[models]
hunter = "your-configured-model"
chat_base_url = "https://your-configured-endpoint/v1"
chat_api_key_env = "YOUR_MODEL_KEY"
```
The default hook never resolves a model endpoint. With explicit configuration it sends
only redacted, already-admitted witness/consequence/repair summaries; it sends no
unadmitted candidates or source tree. The model may select an existing witness index,
not author claims or raise evidence strength. Invalid responses and timeouts retain
the deterministic explanation. Requests use the remaining transaction deadline; the
artifact records model, endpoint/prompt hashes, usage, elapsed time and recorded cost
(or explicitly unknown cost when pricing/usage is unavailable or a call is interrupted).
There is no call when no admitted witness exists, including with the current empty
capability registry. Analysis caches remain deterministic; optional presentation is
recomputed after admission and never reuses a cached model decision.
Pre-push does not implicitly read the working tree's `.env`. Supply any configured
credential variable in the Git process environment. Explicit model configuration is
read under the same analysis deadline.
