Variants

Status(String)

A one-line status update from a domain path (the 2e step converts the status field writes into these; the field still exists until then).

ComposerSet(String)

The composer should be replaced with this text (e.g. a send-failure path restoring the user’s message). The view layer applies it to its TextArea.

ComposerClear

The composer should be cleared.

ViewportReset

The view should reset its viewport state (scroll, selection, pinning baseline) — pushed wherever domain code switches sessions, starts a stream, or otherwise invalidates the rendered conversation.

HistoryInvalidated

The wrapped-history render cache must be rebuilt (in-place message edits would otherwise leave stale wrapped content).

OpenLoginPopup

A domain path fell back to “no backend configured” and wants the login selector shown (e.g. a swarm turn with no resolvable model).

Gate(Option<GateState>)

A survey/plan gate armed (Some) or cleared (None). GateState carries the session id the reply must come from, so a gate in another session can never swallow typing — the consumer compares the payload against the viewed session.

Stream(Option<(ChatTaskId, StreamEvent)>)

Models(Option<Result<Vec<Model>, String>>)

Title(Option<(String, String, String)>)

A generated session topic: (session id, title, slug).

Memory(Option<(String, Vec<MemoryOp>)>)

Extracted memory ops for a space, tagged with the space name so a meanwhile space-switch can discard stale results.

Compact(Option<(String, String, i64, u64)>)

A compaction digest: (session id, digest, messages covered, pre-compaction %).

SkillInstall(Option<Result<String, String>>)

Result of /skills install: skill name on success, error message on failure.

Ocr(Option<(String, String, OcrUpdate)>)

A per-page progress or final OCR result for one scanned PDF, or None when the batch’s channel closed.

Embed(Option<EmbedMsg>)

One file’s chunk-embedding job finished (or the channel closed).

OcrPull(Option<Result<String, String>>)

A local-OCR-model pull finished: model name or error.

Research(Option<ResearchMsg>)

A deep-research pipeline update, or None when its channel closed.

ResearchTopic(Option<Result<String, String>>)

/research with no topic: a distilled topic from recent chat, or an error.

UpdateCheck(Option<String>)

Startup update check: newest published version, or None when the check failed (offline, index hiccup) — silently ignored.

Login(Option<LoginMsg>)

OpenAI Codex subscription login status or final result.

Swarm(Option<(String, SwarmUpdate)>)

A /swarm turn update, or None when its channel closed.
