Fail over acquisition without competing active workers
Platform Operator · Trigger: A redundant runtime must take over.
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 satisfiedFailover tests will demonstrate fencing, checkpoint continuity and declared duplicate handling.
Run the remaining steps below. The result is read back from record state — nothing here is a toast.
Normal path
Replay, backfill or reprocessing is bounded, authorised, executed and reconciled — three distinct operations.
Step 1. Preview the bounded impact before anything is re-emitted.

Exception path
A partitioned former owner will not continue publishing as an authorized leader.
Alternate path. Impact exceeds the preview: stop and escalate rather than continuing the operation.

Workflow as specified
CoreSync will use an approved lease or fencing mechanism and transfer compatible checkpoint state so old and replacement workers cannot both claim active ownership.
