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.

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. +- `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 changed component source for unresolved implementation markers: +Checked `src/**/*.py`
