The signal that came back
A system event becomes a resolved human loop when its acknowledgement returns through a signed outgoing webhook.

An incoming webhook turned a system event into a Ping.
But delivery was only half the loop.
A confirmation request stayed open while a person responded.
A signed outgoing webhook returned the acknowledgement with the same correlation ID.
Software rang the room.
A person confirmed it.
Software knew what happened next.
The useful path was never only from a server to a phone.
It was from an event to a human response—and back.
