Replay

Use replay as a scoped repair tool.

Replay rebuilds projections from the immutable event store. It must be scoped by organization and environment, previewed first, and confirmed outside local-only flows.

1. Select one organization and one environment.
2. Run preview and inspect affected event and projection counts.
3. Confirm only when the scope is correct.
4. Watch failed events, dead letters, projection lag, and external notifications after replay.
