+# Room App UI — handoff
+
+## Summary
+
+Bots can publish a declarative UI into Matrix room state (`im.paarrot.ui`). Paarrot takes over the room view with that UI. User interactions are sent as timeline events (`im.paarrot.ui.action`), not chat messages. The bot updates state to re-render panels.
+
+## User-facing behavior
+
+- When a room has a valid `im.paarrot.ui` state event, opening the room shows the app UI instead of the chat timeline (forum rooms still win over app UI).
+- **Show chat** returns to the normal timeline without clearing bot state; a banner offers **Show app** to go back.
+- Action events are hidden from the chat timeline (same as confetti relay events).
+- Room settings → Permissions includes **Set Room App UI** and **Send Room App Actions**.
+
+## Architecture
+
+```
+Bot → state im.paarrot.ui
+  → Room.tsx detects via useStateEvent
+    → RoomAppView → RoomAppSchema (declarative nodes)
+      → user clicks → mx.sendEvent(im.paarrot.ui.action)
+        → Bot updates im.paarrot.ui → live re-render
+```
+
+## Key files
+
+| Path | Role |
+|------|------|
+| `cinny/src/types/matrix/room.ts` | `StateEvent.PaarrotUi`, `MessageEvent.PaarrotUiAction`, node types |

+
+## Data model
+
+| Event | Kind | Content |
+|-------|------|---------|
+| `im.paarrot.ui` | state (`""`) | `{ version, title?, css?, root }` |
+| `im.paarrot.ui.action` | timeline | `{ action, component_id, value?, values?, ui_event_id? }` |
+
+See [samples/](./samples/) for pasteable Developer Tools payloads.
+
+MVP node types: `panel`, `row`, `text`, `button`, `input`, `select`, `image`, `spacer`.
+
+## Dependencies
+
+- folds UI primitives
+- matrix-js-sdk `sendEvent` / state sync
+- No bot-supplied JavaScript; CSS is sanitized and scoped under `[data-room-app]`
+
+## Integration points
+
+- Same room takeover pattern as forums (`Room.tsx` branch)
+- Developer Tools can send state/events for demos without a bot process
+
+## Testing
+
+### Manual
+
+1. In Developer Tools → Send State Event, type `im.paarrot.ui`, paste `samples/trivia-ui-state.json`.
+2. Open the room — app UI should replace the timeline.
+3. Click an answer — an `im.paarrot.ui.action` event is sent (hidden in timeline; visible in raw/dev tools).
+4. Click **Show chat**, then **Show app**.
+5. Clear state content / redact state to restore normal chat.
+
+### Automated
+
+- None yet
+
+## Known issues & gotchas
+
+- CSS scoping is best-effort, not a full CSS parser
+- Images allow `mxc://`, `https://`, and `http://` only
+- Forum rooms take priority over app UI
+- `sendEvent(..., as any)` cast mirrors other custom event types
+
+## Future work
+
+- `form` / `tabs` / `markdown` / `progress` nodes
+- Bot SDK helpers
+- Stronger CSS sandbox (Shadow DOM)
+- Encrypt custom action payloads helpers if needed
+
+## Related docs
+
+- [samples/trivia-ui-state.json](./samples/trivia-ui-state.json)
+- [samples/ui-action-event.json](./samples/ui-action-event.json)
+
+## Add your extra things here
+
+- Power level: bots need PL ≥ `state_default` (usually 50) or an explicit level for `im.paarrot.ui`
+- Action events use normal message event power levels unless overridden for `im.paarrot.ui.action`
