# Product Implementation Completeness Report

**Cycle**: 1
**Date**: 2026-05-05
**Outcome**: Product implementation complete

## Summary

All product implementation tasks for cycle 1 are implemented or have explicit runtime prerequisite boundaries. The remediation tasks close the previously identified gaps in native VIO selection, local descriptor/index VPR retrieval, and computed anchor matching/geometry verification.

## Product Task Classifications

| Task | Classification | Evidence |
|------|----------------|----------|
| AZ-219 through AZ-232 | PASS | Prior batch reports 01-09 and cumulative review 01-09 |
| AZ-240 | PASS | `src/vio_adapter/interfaces.py`, `src/vio_adapter/native/__init__.py`, `tests/unit/test_vio_adapter.py` |
| AZ-241 | PASS | `src/satellite_service/interfaces.py`, `src/satellite_service/types.py`, `src/satellite_service/native/__init__.py`, `tests/unit/test_satellite_service_vpr.py` |
| AZ-242 | PASS | `src/anchor_verification/interfaces.py`, `src/anchor_verification/types.py`, `src/anchor_verification/native/__init__.py`, `tests/unit/test_anchor_verification.py` |

## Remediation Evidence

- VIO now exposes `NativeVioBackend` behind the `VioBackend` protocol, fills latency metrics, maps initialization/runtime failures into explicit health/error envelopes, and keeps WGS84 authority out of the adapter.
- Satellite retrieval now loads local descriptor/index packages from cache files, builds a CPU FAISS-compatible descriptor index, requires query descriptors for retrieval, and degrades safely for missing or invalid index data.
- Anchor verification now computes matcher evidence from frame/tile keypoints through `KeypointRansacMatcher`, reports runtime/quality metrics, and routes computed evidence through the existing freshness, provenance, inlier, MRE, and homography gates.

## Marker Scan

Checked changed component source for unresolved implementation markers:

- `src/vio_adapter`: clean
- `src/satellite_service`: clean
- `src/anchor_verification`: clean

## Verification

- `python3 -m pytest tests/unit/test_vio_adapter.py tests/unit/test_satellite_service_vpr.py tests/unit/test_anchor_verification.py`: 19 passed.
- `python3 -m pytest`: 58 passed.
- `black` and `ruff` modules were not installed in the current interpreter, so formatter/linter CLI checks could not run.

## Required Follow-Up

No product remediation tasks remain. Autodev may advance to Step 8, Code Testability Revision.
