# Replayer
A replay reads a recorded payload set, runs it through the current mapping, and
diffs the produced events against what was billed at the time.
## Using a replay
- Keys used for idempotency must exclude the delivery timestamp, or a retry looks new
- A diff with only ordering changes is expected: ordering is per-tenant, not global
