# Product Implementation Completeness Report

**Cycle**: 1
**Date**: 2026-05-06
**Outcome**: PASS — product implementation complete after native VIO remediation

## Summary

Product implementation returned to Step 7 for the native VIO runtime gap and completed AZ-243. Production and Jetson VIO profiles now select native runtime mode, load a BASALT-compatible runner through the VIO adapter boundary, and report explicit initialization errors when the installed runtime prerequisite is unavailable. Replay behavior remains available through explicit development replay configuration.

## Product Task Classifications

| Task | Classification | Evidence |
|------|----------------|----------|
| AZ-219 through AZ-232 | PASS | Batch reports 01-09, cumulative review 01-09, full source marker scan, and full suite coverage |
| AZ-240 | PASS | `src/vio_adapter/interfaces.py`, `src/vio_adapter/types.py`, `src/vio_adapter/native/basalt.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` |
| AZ-243 | PASS | `create_vio_adapter`, `VioRuntimeConfig`, `ConfiguredNativeVioBackend`, `BasaltNativeRunner`, `tests/unit/test_vio_adapter.py`, `tests/blackbox/test_vio_replay.py` |

## Remediation Evidence

- `VioRuntimeConfig` derives native mode for `production` and `jetson` profiles and rejects replay mode for those environments.
- `create_vio_adapter` selects `ConfiguredNativeVioBackend` for native profiles and keeps replay execution behind explicit replay mode.
- `BasaltNativeRunner` loads an installed BASALT-compatible runtime factory from the configured module/function reference and validates the returned runner against `NativeVioRunner`.
- Missing BASALT runtime prerequisites surface as explicit VIO initialization errors with failed health and no emitted VIO state packet.
- Satellite retrieval and anchor verification remediation from AZ-241 and AZ-242 remains covered by the existing native retrieval/matching evidence and tests.

## Marker Scan

Checked `src/**/*.py` for unresolved implementation markers:

- `TODO`
- `placeholder`
- `stub`
- `fake`
- `mock`
- `scaffold`
- `native bridge`
- `NotImplemented`
- bare `pass`

Result: clean.
