social.colibri.sync ยท 3- social.colibri.sync.sendHum procedure not from the namespace authority Informs this AppView of an off-protocol event that occurred on a peer AppView. Requires inter-service auth: a JWT signed by the caller's AppView signing key, aud = this AppView's did:web, lxm = social.colibri.sync.sendHum. The receiver drops the Hum unless the JWT issuer equals both the envelope `origin` and the `subject`'s declared presenceService.
- social.colibri.sync.subscribeEvents subscription not from the namespace authority Opens a WebSocket stream that transmits relevant events for the authenticated user.
- social.colibri.sync.subscribeHums subscription not from the namespace authority Egress-only WebSocket stream of Hums this AppView is relaying. Peers subscribe to receive off-protocol events for shared communities, optionally narrowing to declared `communities` (repeated query param). Requires inter-service auth (subprotocol-carried, as with subscribeEvents). Clients cannot send messages on this stream.
