# Code Review Report

**Batch**: AZ-231_anchor_verification_matching
**Date**: 2026-05-03
**Verdict**: PASS

## Findings

No findings.

## Review Scope

- Task spec:
  - `_docs/02_tasks/todo/AZ-231_anchor_verification_matching.md`
- Changed files:
  - `src/anchor_verification/__init__.py`
  - `src/anchor_verification/interfaces.py`
  - `src/anchor_verification/types.py`
  - `tests/unit/test_anchor_verification.py`

## Phase Notes

### Spec Compliance

- AZ-231 AC-1 is covered by `test_candidate_verification_emits_acceptance_evidence`.
- AZ-231 AC-2 is covered by `test_unsafe_candidate_is_rejected_with_reason`.
- AZ-231 AC-3 is covered by `test_matcher_benchmark_reports_profile_runtime_and_quality_metrics`.

### Code Quality

The implementation keeps evidence/result models in `types.py`, gate behavior in `interfaces.py`, and public exports in `__init__.py`. The benchmark path computes each verification result once and reports runtime/quality metrics per matcher profile.

### Security Quick-Scan

No network calls, shell execution, dynamic code execution, hardcoded secrets, or credential logging were introduced.

### Performance Scan

Anchor verification is request/trigger oriented and does not add a per-frame learned matcher loop. Benchmark reporting is bounded by the provided evidence tuple.

### Cross-Task Consistency

The verifier consumes `VprCandidate` outputs from Satellite Service and emits shared `AnchorDecision` DTOs for the later safety wrapper task.

### Architecture Compliance

Imports respect `_docs/02_document/module-layout.md`: Anchor Verification imports shared contracts only and does not reach into Satellite Service or Tile Manager internals.
