SessionReplaced(Vec<Message>)

The session was replaced (/new cleared it, or /resume loaded a stored one). Carries the new transcript so the TUI can rebuild state.messages. Empty Vec = a fresh session.

ModelSwitched(ModelId)

The active model changed successfully.

ForkCandidates(Vec<(String, String)>)

Refreshed /fork candidate list (active-branch user messages, newest first) — (EntryId, preview) pairs. The binary emits this at startup and after every turn so the picker is never stale.

BranchTree(BranchTree)

Refreshed session branch tree — the binary emits this at startup and after every turn so the /tree view is never stale.

Error(String)
