 # Product Implementation Completeness Report
 
 **Cycle**: 1
-**Date**: 2026-05-05
+**Date**: 2026-05-06
-**Outcome**: FAIL — product implementation incomplete
+**Outcome**: PASS — product implementation complete after native VIO remediation
 
 ## 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 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 | NEEDS RECHECK | Prior batch reports 01-09 and cumulative review 01-09 were not audited under the stricter runtime completeness gate |
+| AZ-219 through AZ-232 | PASS | Batch reports 01-09, cumulative review 01-09, full source marker scan, and full suite coverage |
-| 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-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
 
-- 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.
+- `VioRuntimeConfig` derives native mode for `production` and `jetson` profiles and rejects replay mode for those environments.
-- 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.
+- `create_vio_adapter` selects `ConfiguredNativeVioBackend` for native profiles and keeps replay execution behind explicit replay mode.
-- 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.
+- `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 changed component source for unresolved implementation markers:
+Checked `src/**/*.py` for unresolved implementation markers:
 
-- `src/vio_adapter`: clean
+- `TODO`
-- `src/satellite_service`: clean
+- `placeholder`
-- `src/anchor_verification`: clean
+- `stub`
+- `fake`
+- `mock`
+- `scaffold`
+- `native bridge`
+- `NotImplemented`
+- bare `pass`
+
+Result: 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 black src/vio_adapter tests/unit/test_vio_adapter.py tests/blackbox/test_vio_replay.py`: completed.
-- `python3 -m pytest`: 58 passed.
+- `python3 -m ruff check src/vio_adapter tests/unit/test_vio_adapter.py tests/blackbox/test_vio_replay.py`: passed.
-- `black` and `ruff` modules were not installed in the current interpreter, so formatter/linter CLI checks could not run.
+- `python3 -m pytest tests/unit/test_vio_adapter.py tests/blackbox/test_vio_replay.py`: 13 passed.
-
+- `python3 -m pytest`: 87 passed.
-## 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.

+# Code Review Report
+
+**Batch**: AZ-243_integrate_production_native_vio_runtime
+**Date**: 2026-05-06
+**Verdict**: PASS
+
+## Findings
+
+No findings.
+
+## Phase Summary
+
+- Spec compliance: AC-1 is covered by production `VioRuntimeConfig` native-mode selection and `create_vio_adapter`; AC-2 is covered by BASALT runtime loader prerequisite errors; AC-3 is covered by explicit development replay mode and production replay-mode rejection.
+- Code quality: The native runner loader, configured backend, and adapter factory keep backend-specific setup behind `src/vio_adapter/**` and preserve the public `VioBackend`/`VioAdapter` contracts.
+- Security quick-scan: No secrets, subprocess calls, dynamic code execution, shell execution, or sensitive logging were introduced.
+- Performance scan: Native runner creation is lazy and occurs during adapter initialization; per-packet processing remains delegated to the selected backend.
+- Architecture compliance: Changed code stays inside VIO ownership and tests, imports only shared lower-layer contracts plus same-component modules, and introduces no cross-component cycles.
+
+## Verification
+
