Edits and deletes of federated messages are fanned out from the home server. The client must apply them to already-rendered messages, including remote-homed ones.

What to do

• Apply message update (edited content / edited_at) and message delete events keyed by qualified message ID.
• Cover both directions: edits/deletes originating locally and those arriving from a remote home.

Acceptance

• Editing/deleting a federated message updates all participants' views.

Server reference

• Edit/delete fanout: commits 9cd7a3c and 8f2ad51; forwarding in src/federation/forward.rs.

Client touch points

• lib/features/messaging/controllers/accord_messages.dart.
