# Code Review Report

**Batch**: AZ-230_satellite_service_vpr_retrieval
**Date**: 2026-05-03
**Verdict**: PASS

## Findings

No findings.

## Review Scope

- Task spec:
  - `_docs/02_tasks/todo/AZ-230_satellite_service_vpr_retrieval.md`
- Changed files:
  - `src/satellite_service/__init__.py`
  - `src/satellite_service/interfaces.py`
  - `src/satellite_service/types.py`
  - `tests/unit/test_satellite_service_vpr.py`

## Phase Notes

### Spec Compliance

- AZ-230 AC-1 is covered by `test_valid_local_index_load_reports_ready_status`.
- AZ-230 AC-2 is covered by `test_loaded_index_returns_bounded_candidates_with_freshness`.
- AZ-230 AC-3 is covered by `test_missing_index_degrades_with_explicit_no_candidate_result`.
- Descriptor-fidelity gating is covered by `test_descriptor_fidelity_gate_rejects_large_optimized_delta`.

### Code Quality

The implementation follows the existing component pattern: public Pydantic models live in `types.py`, behavior and protocols live in `interfaces.py`, and component exports are centralized in `__init__.py`.

### Security Quick-Scan

No network calls, shell execution, dynamic code execution, hardcoded secrets, or credential logging were introduced. Retrieval only uses local preloaded descriptor records.

### Performance Scan

Candidate scoring is bounded by the loaded local index and request `top_k` is constrained to 50. The implementation does not add a steady-state per-frame retrieval loop.

### Cross-Task Consistency

The retrieval code reuses the Satellite Service sync boundary’s offline-only posture and shared `VprCandidate`/`ErrorEnvelope` contracts.

### Architecture Compliance

Imports respect `_docs/02_document/module-layout.md`: Satellite Service imports shared contracts/errors and Tile Manager through public package exports only.
