commucat-federation

Utilities for signing and validating inter-domain events.

• FederationEvent – canonical representation of an outbound event (identifier, origin domain, JSON payload, scope).
• sign_event / verify_event – Ed25519 signatures over a BLAKE3 digest, compatible with commucat-crypto::EventSigner / EventVerifier.
• PeerDescriptor – metadata describing trusted peers (domain, endpoint, public key, last-seen timestamp).

The crate is used by the server to enqueue outbound events into the federation outbox and to verify inbound payloads delivered through /federation/events. It focuses purely on message authenticity; transport, retries and monitoring are handled by the server crate.
