gsp-protocol

Group Signaling Protocol — signalling sub-protocol of the Group Protocol Stack.

GSP carries membership, role and stream-state events on top of the GBP base layer with reliable delivery and request_id deduplication.

Receive-side pipeline

Per GSP §7:

1. Decrypt (handled by GBP).
2. Check sender authorisation.
3. Validate the args schema.
4. Apply the effect atomically.
5. Emit ACK / NACK.

What this crate provides

• GspSignal — the CBOR-encoded signal envelope.
• GspClient — stateful client that maintains request_id deduplication, the mute-list, the current membership set and signal_type decoding.
