Fixed incremental NativeDB updates against legacy persisted history with non-positive timestamps. Incoming provider frames remain strictly validated, while merge repair discards invalid persisted rows before concat, dedupe, ordering, canonical-index rewrite, and atomic publication.
The regression reproduces the observed MNQ baseline shape: one epoch-zero row, noncanonical absolute indexes, extra derived columns, and a valid fresh IB frame. It proves the invalid row is removed while all valid old and new bars survive with canonical indexes.
Verification generated with the patch:
- NativeDB regressions: 18 passed
- history backfill regressions: 6 passed
