Webhook lifecycle

An owner can hold at most 5 live webhook subscriptions. Live includes verification, active, dormant, and paused control states defined by the generated contract.

Endpoint verification

The initial delivery cursor begins at the first successful endpoint verification. Endpoint replacement creates a visible reverification gap and resumes with new events only.

Verification request fixture and verification response fixture.

Connection binding

A subscription belongs to the exact REST connection that created it. Filters and replays bind to immutable normalized revisions. Queued work binds to endpoint and control generations.
