Function: selectStatus()

selectStatus(events): StatusState | null

Defined in: src/recorders/observability/status/statusTemplates.ts:111

Derive the current thinking state from the event log.

Single forward walk that tracks "active" state for each domain: • pause — set on pause.request, cleared on pause.resume • tool — set on tool.start, cleared on matching tool.end (matched by toolCallId for parallel-tool safety) • llm — set on llm.start, cleared on llm.end

Priority order (highest first):

1. ACTIVE PAUSE wins. When the agent is waiting on the human, that's what the chat should show — not the underlying tool that triggered the pause.
2. ACTIVE TOOL — the LLM said "use a tool" and the tool is running. Show "Working on <toolName>…".
3. ACTIVE LLM — call in flight. Show streaming tokens if any arrived, otherwise "Thinking…".
4. Otherwise null (bubble hidden).

Pure projection. Forward walk is O(n); a closing event correctly cancels its matching opener so a completed tool.start/tool.end pair leaves the state quiescent.
