Database Operator · Trigger: A connector falls behind the retained source log.
Simulated fixture data. Every record, receipt and timeline entry on this screen is demonstration material. It is never production evidence.
Acceptance
3 of 4 steps satisfiedRecovery evidence will identify the gap, reconstruction method and residual uncertainty.
Run the remaining steps below. The result is read back from record state — nothing here is a toast.
Normal path
A snapshot or change stream is captured, deployed and reconciled against the source of record.
Step 1. Validate the capture definition and its restart position.

Exception path
It will not resume from the current position while concealing the missing interval.
Alternate path. Capture position is lost: plan a bounded re-capture instead of a blind full reload.

Workflow as specified
CoreSync will detect the invalid resume position, report the affected interval and execute an approved resnapshot or comparison plan under source-load limits.
