Waypoint drag:
- Use observeDeep instead of observe to detect Y.Map property changes
Host election:
- Extracted to host-election.ts with 8 unit tests
- Simple rule: lowest real client ID is always host, deterministic
- Always sets role (host or participant), no missing roles
- Filters server docs (empty awareness state) from election
BRouter routing:
- Route segment-by-segment like bikerouter.de (one request per
waypoint pair), guarantees route passes through every waypoint
- Merge GeoJSON segments with accumulated stats
- 8 unit tests for segment merging and waypoint splitting
Awareness cleanup:
- Track client IDs per WebSocket connection
- Immediately remove awareness on WebSocket close
Debug panel:
- Visibility + expanded state persisted in localStorage
- Hotkey (Shift+Cmd+Option+T) toggles visibility
- Labels server docs as (server)
- All logic self-contained in YjsDebugPanel.tsx
User identity:
- Color and name persisted in localStorage across reloads
Tests: 32 total (16 existing + 8 host election + 8 routing)

- Add Vite plugin implementing y-protocols sync server for dev mode
- Fix useYjs hook: move provider creation into useEffect to survive
React StrictMode remounts
- Fix WebSocket URL: use /sync as base (y-websocket appends room name)
- Verified in browser: Connected status, Host badge, awareness working

Added Y.Map observer on routeData that triggers route recomputation
when the 'profile' key changes. Previously profile changes synced
via Yjs but didn't trigger a new BRouter request.

- Yjs WebSocket server at /sync/:sessionId for real-time collaboration
- Session creation API (POST /api/sessions) with optional GPX initialization
- Session join page with Planner layout (header, map area, sidebar)
- In-memory session store (PostgreSQL persistence deferred to infra setup)
- Custom production server entry with WebSocket upgrade handling
- Vite path aliases (~/) for clean imports
- Fix tsconfig for apps: noEmit, exclude build dir
Tasks completed: 4.1, 4.3, 4.4, 4.5
Deferred: 4.2 (PostgreSQL), 4.6-4.8 (need client-side Yjs from Group 6)
