feat(sidebar): per-thread agent presence indicators#58
Merged
Conversation
Adds 16px breathing-avatar stack above each sidebar thread row's time
stamp, surfacing which agents currently have a live run inside that
thread. Aggregates the per-item presence (v0.1) up to (thread_id,
agent_id) so the sidebar answers "which threads are hot" while the
thread-item-tail indicator still answers "hot in which step".
Backend (forge_store.summarize_thread):
- Scans live status_chip posts for phase in {thinking, running}
- Returns active_agents: [{agent_id, started_at}] with the EARLIEST
started_at per agent so the v1.1 long-tail grey-ring threshold can
fire when any item in the thread is stuck >5min
- Skips __router__ and resolves legacy chips by content fallback
Frontend (renderThreadList / renderSidebarPresence + style.css):
- New .sb-presence stack: up to 3 slots + "+N" overflow, -5px overlap
- Blue breathing ring (1.6s) for active, static grey ring once a slot
is >=5min old (v1.1 hook, zero event-layer cost)
- No fail/timeout dwell on the sidebar layer per spec (run end =>
immediate removal); navigation strip must not mimic an unread badge
- aria-label/title tooltips, prefers-reduced-motion disables animation,
dark-mode ring colour shift
