Replay closes the loop only because deduplication holds: reprocessing an event range re-decides but does not re-send what was already delivered.

Why the loop closes
Replay is only safe because deduplication holds — reprocessing re-decides but does not re-send what was already delivered
Verification is an explicit step: the duplicate-suppression counter is what proves the replay was safe
Without that counter, replay is a hope rather than a procedure
Targets
Triage to failure class under 10 minutes, using one trace
DLQ drained within one business day for P1, within one hour for P0
Every incident produces either a runbook change or an alert change; no incident closes with neither
Assumption
One on-call rotation covers the platform; per-channel ownership would need a different escalation design
