## Prompt
|
|
|
|
Diagnose the live `pikerd` failure where backfill publication raised
|
|
`ValueError: OHLCV timestamps must be finite and positive` while merging the
|
|
known gappy MNQ NativeDB baseline with fresh IB history. Determine whether to
|
|
commit the pending audit stack or iterate first.
|
|
|
|
## Response summary
|
|
|
|
Traced the primary failure through `publish_latest_frame()` to
|
|
`NativeStorageClient.update_ohlcv()`. The incoming frame was valid, but the
|
|
canonicalized persisted baseline retained its epoch-zero row and caused the
|
|
merged frame to fail validation. Added persisted-row repair before merge and
|
|
a regression using the observed legacy schema characteristics.
|
|
|
|
