Messages in a federated space may be authored by remote users and/or homed on a remote server (origin set, qualified author ID).

What to do

• Resolve qualified author IDs to the mirrored remote user profile for the author line/avatar.
• Optionally show an origin indicator on messages whose origin differs from the space's connected server.
• Make sure message dedup/ordering keys use the qualified message ID.

Acceptance

• Remote-authored messages display the correct author identity and avatar.
• No duplicate or mis-ordered messages when home-authored and replica copies arrive.

Server reference

• origin on Message: src/models/message.rs; message payload: message_payload in src/federation/outbound.rs.
• Remote-homed message round-trip: commit 6b478c1.

Client touch points

• lib/features/messaging/controllers/accord_messages.dart, lib/features/messaging/components/box/accord_message_content.dart.
