Prompt
Inspect the completed NVDA 60s SHM backfill before workspace restart, explain the persistent zero region, and continue fixing the indexing logic so sparse IB history does not leave physical null reservations.
Response summary
Captured a 42,720-row live SHM null span whose valid margins shared the same timestamp. Replaced wall-clock row reservation with actual provider-boundary placement, fixed stale SHM first-index, endpoint insertion and field-map semantics, published the final storage prepend, and added a full multi-frame tsdb_backfill() regression using a real ShmArray.
Files changed
