Description
Add explicit crash-gap disclosure. Sequence-gap detection cannot reveal records that were never written at the end of a crashed process. Each producer should persist a startup marker and remove it on graceful shutdown. After an unclean restart, it should emit a signed EVIDENCE_GAP_DISCLOSED record describing the possible missing interval, last durable sequence, restart time, and reason.
