+## Phase 6 status (2026-08-30 ~13:00)
+Done:
+- `MediaPanelView` expanded: search section (query + Find button, results with "in library" tag), choices section (agent-offered suggestions from state), library section (list with Play/Remove per track, refresh button), add-stream section (name + URL form).
+- `MediaPlayerController.playVideo` / `playTrack`: send POST /play to the scoped room or "default" when no session is active.
+- `startDefaultPolling()`: Media Panel starts 1.5s state polling on appear so Now Playing card reflects server state without a voice session.
+- `pollState` now logs failures instead of silently swallowing them.
+- `absolute()` helper prefixes server base URL for relative art paths.
+- Stream URL field: `.textInputAutocapitalization(.never)` to prevent "Https://" capitalization.
+
+Verified in simulator (log + UI + server evidence):
+- Search: typed "toes", tapped Find → POST /media/api/search 200 → results rendered with "in library" tag on matching track.
+- Play (library): tapped Play on "Toes" → POST /media/api/play 200 → state `desired: playing` confirmed via curl. AVPlayer attempted to decode webm and failed (-11828, expected platform limitation from Phase 5).
+- Delete: tapped Remove on "Toes" → confirmation alert "Remove from library?" → tapped Remove → DELETE /media/api/tracks/XMh9vU4g0jc 200 → library refreshed to show only Sheryl Crow.
+- Add Stream: entered name + URL, tapped Add → POST /media/api/streams 400 (server rejected test URL) → error message "Could not add stream: Media API request failed with HTTP 400. url must be http(s)" displayed in red.
+- Polling without session: confirmed via AVPlayer webm decode error in logs (state was fetched and reconciled even though no voice session was active).

 ## Subagent notes
 - Small context model: keep prompts self-contained, point at this file + UPDATE_PATH.md
 - Watch for loops (repeated identical commands) — kill and redirect if seen
