Stand up a Shared Signals receiver — and drain its queue

Create a poll stream, subscribe yourself as a subject, then poll: verifiable SETs, drained and acked.

1. 1

   On the CAEP lab, generate an SSF bearer token (shown once) and create a poll stream.

   This is the SSF §7 stream-management API a real receiver calls first — the token, hashed at rest, is what every subsequent bearer call resolves back to your own sandbox transmitter.

2. 2

   Subscribe your own account as a subject, then trigger an event.

   A signal only ever queues into a stream that BOTH wants that event type AND has the subject registered — the same two-part match a real transmitter runs before it ever queues a SET.

3. 3

   Poll now and read the drained, decoded SET — then watch a second poll come back empty.

   RFC 8936 poll delivery is at-least-once: an un-acked SET is redelivered on every poll. Draining it acks its jti, so the next poll is empty — and the SET you read is a REAL ES256 JWS, verifiable against the same JWKS the CAEP receiver checks.
