- /watch resolves the target READ-ONLY: sessions are validated against
registered workspace listings (current or any other) without binding the
conversation or switching workspaces. /unwatch and /watchlist round out
the command set; the watchlist card supports button and number-reply
unwatching.
- Watches persist in the state store (sessionId + title + chatId + lastSeq)
and resume at runtime start: the bridge starts the global event-mux
watcher in its constructor when the harness supports it.
- Completion pushes fire on turn/end, deduped by sessionId + turn id, with
the seq watermark persisted per watch. After a mux reconnect the bridge
replays each watched session's recent history (session.history) through
the normal handler, so missed turn/end events are compensated without
duplicates.
- Bound-session push targets are persisted (chatTargets) instead of living
only in memory, and refresh on every accepted message.
- Watch failures map to safe user-facing messages.
Local UX enhancements on top of upstream ce8b9e8:
- harness-client.mjs: add toEpochMs/sessionTimeMs, attach time to sessions
- workspace-command.mjs: /sessionlist relative time, /session N index binding
