Description

Evolve MapShapeUtil.tsx to integrate the 6 implemented subsystems (privacy, mycelium, lenses, conics, discovery, presence) into the canvas map shape. Currently the MapShape is a standalone map viewer - it needs to become the central hub for all open-mapping features.

Acceptance Criteria

  • #1 MapShape props extended for subsystem toggles
  • #2 Presence layer integrated with opt-in location sharing
  • #3 Lens system accessible via UI
  • #4 Route/waypoint visualization working
  • #5 Collaboration sync via Automerge
  • #6 Discovery game elements visible on map

Implementation Notes

MapShape Evolution Progress (Dec 5, 2025):

Completed:

  1. Extended IMapShape Props - Added comprehensive subsystem configuration types:

    • MapPresenceConfig - Location sharing with privacy levels
    • MapLensConfig - Alternative map projections
    • MapDiscoveryConfig - Games, anchors, spores, hunts
    • MapRoutingConfig - Waypoints, routes, alternatives
    • MapConicsConfig - Possibility cones visualization

  2. Header UI Controls - Subsystem toolbar with:

    • ⚙️ Expandable subsystem panel
    • Toggle buttons for each subsystem
    • Lens selector dropdown (6 lens types)
    • Share location button for presence
    • Active subsystem indicators in header

  3. Visualization Layers Added:

    • Route polyline layer (MapLibre GeoJSON source/layer)
    • Waypoint markers management
    • Routing panel (bottom-right) with stats
    • Presence panel (bottom-left) with share button
    • Discovery panel (top-right) with checkboxes
    • Lens indicator badge (top-left when active)

Still Needed:

  • Actual MapLibre marker implementation for waypoints
  • Integration with OSRM routing backend
  • Connect presence system to actual location services
  • Wire up discovery system to anchor/spore data

Additional Implementation (Dec 5, 2025):

Routing System - Fully Working:

  • ✅ MapLibre.Marker implementation with draggable waypoints
  • ✅ Click-to-add-waypoint when routing enabled
  • ✅ OSRM routing service integration (public server)
  • ✅ Auto-route calculation after adding/dragging waypoints
  • ✅ Route polyline rendering with GeoJSON layer
  • ✅ Clear route button with full state reset
  • ✅ Loading indicator during route calculation
  • ✅ Distance/duration display in routing panel

Presence System - Fully Working:

  • ✅ Browser Geolocation API integration
  • ✅ Location watching with configurable accuracy
  • ✅ User location marker with pulsing animation
  • ✅ Error handling (permission denied, unavailable, timeout)
  • ✅ "Go to My Location" button with flyTo animation
  • ✅ Privacy level affects GPS accuracy settings
  • ✅ Real-time coordinate display when sharing

Still TODO:

  • Discovery system anchor visualization
  • Automerge sync for collaborative editing

Phase 5: Automerge Sync Integration - Analyzing existing sync architecture. TLDraw shapes sync automatically via TLStoreToAutomerge.ts. MapShape props should already sync since they're part of the shape record.

Automerge Sync Implementation Complete (Dec 5, 2025):

  1. Collaborative sharedLocations - Added sharedLocations: Record<string, SharedLocation> to MapPresenceConfig props

  2. Conflict-free updates - Each user updates only their own key in sharedLocations, allowing Automerge CRDT to handle concurrent updates automatically

  3. Location sync effect - When user shares location, their coordinate is published to sharedLocations with userId, userName, color, timestamp, and privacyLevel

  4. Auto-cleanup - User's entry is removed from sharedLocations when they stop sharing

  5. Collaborator markers - Renders MapLibre markers for all other users' shared locations (different from user's own pulsing marker)

  6. Stale location filtering - Collaborator locations older than 5 minutes are not rendered

  7. UI updates - Presence panel now shows count of online collaborators

How it works:

  • MapShape props sync automatically via existing TLDraw → Automerge infrastructure

  • When user calls editor.updateShape() to update MapShape props, changes flow through TLStoreToAutomerge.ts

  • Remote changes come back via Automerge patches and update the shape's props

  • Each user only writes to their own key in sharedLocations, so no conflicts occur
