# Product Implementation Completeness Report

**Cycle**: 1
**Date**: 2026-05-05
**Outcome**: FAIL — product implementation incomplete

## Summary

Product implementation was previously marked complete, but Step 11 exposed a false-positive gate: tests passed against scaffold/fake contract behavior while the actual A-Z runtime path, especially real VIO execution, is not implemented. Product implementation must return to Step 7 and create remediation tasks before downstream test gates can be trusted.

## Product Task Classifications

| Task | Classification | Evidence |
|------|----------------|----------|
| AZ-219 through AZ-232 | NEEDS RECHECK | Prior batch reports 01-09 and cumulative review 01-09 were not audited under the stricter runtime completeness gate |
| AZ-240 | FAIL | `src/vio_adapter/interfaces.py` exposes `NativeVioBackend`, but default runtime behavior is `ReplayVioBackend`; `src/vio_adapter/native/__init__.py` only re-exports protocol wrappers and does not execute a real BASALT/native VIO engine |
| 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 currently exposes `NativeVioBackend` behind the `VioBackend` protocol, but the production/native engine is not actually integrated. This is a scaffold, not product-complete VIO.
- 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

Autodev must return to Step 7, rerun the Product Implementation Completeness Gate under the stricter rules, create remediation tasks sized at 5 points or less, and implement the missing runtime behavior before Step 8 or Step 11 may pass.

## Remediation Tasks

- `AZ-243_integrate_production_native_vio_runtime` was created to close the AZ-240 native VIO runtime gap and return Step 7 to product implementation.
