Prompt

The user reran the known IB FQME on backfiller_deep_fixes and reported that publish_latest_frame() still failed because NativeDB required an index absent from IB’s provider frame. The user called out the missed tabular schema boundary and requested an actual end-to-end test suite rather than storage fakes.

Response summary

Repaired the IB-provider-to-NativeDB boundary by canonicalizing durable fields and mapping reloads into provider-specific SHM buffers. Added a local actor/SHM/Parquet integration regression covering first startup and restart, plus focused conversion and timestamp-coercion tests. Two review rounds found and resolved restart hydration and fractional-time hazards.
