 Replays only a dead-lettered campaign wakeup with explicit durable wakeup intent, rechecked under its campaign lock. Once a task binds a contact or sequence for sending, its send intent stays restrictive even after either record is deleted. Legacy or imported tasks without verified wakeup intent and all send-capable tasks return `409 Conflict` and retain their dead-letter evidence. A retry date, JSON payload, null contact/sequence, or missing send marker cannot grant replay. This route requires the send permission rather than plain write access.
 
+Database downgrades refuse to discard this provenance while send-intent or unresolved unverified dead-letter rows exist. Keep the schema and roll forward instead.
