One event on the host’s /v1/events SSE feed — the wire mirror of AppEvent, with every variant mapping 1:1 onto the domain event. Frames serialize as {"type": "<snake_case variant>", "payload": …}; unit variants carry no payload key. A None payload means that source’s channel closed (its background task ended).

Variants

Status(String)

A one-line status update from a domain path.

ComposerSet(String)

The composer should be replaced with this text (e.g. a send-failure path restoring the user’s message).

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.

Gate(Option<WireGateState>)

A survey/plan gate armed (Some) or cleared (None).

Stream(Option<(u64, WireStreamEvent)>)

One chat-frame delta: (task id, stream event) — or None when the task’s channel closed. Carries every frame the stream view renders, so the SSE bridge needs no separate chat pump.

Models(Option<WireModelsResult>)

The model-catalog fetch outcome: the merged per-backend list, or an error string.

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

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

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

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>>)

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

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

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

Embed(Option<WireEmbedMsg>)

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<WireResearchMsg>)

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 by clients.

Login(Option<WireLoginMsg>)

Codex subscription login status or final result.

Swarm(Option<WireSwarmMsg>)

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