Key Files by Purpose

I need to understand how the app flows

→ Read docs/architecture.md + docs/ui-ux-guide.md

I need to add a new exercise

→ Read docs/exercises.md + Scripts/Exercises/ExerciseController.ts

I need to integrate Firebase

→ Read docs/firebase-schema.md + Scripts/FirebaseService.ts

I need to test the home screen

→ Attach SessionManager, LoginController, DevlogModal to scene

I need to test the dashboard

→ Attach TaskListController, ActivityBrowseController + their prefabs

I'm debugging a script error

→ Check IMPLEMENTATION_SUMMARY.md "Debugging Checklist"

I want to know what's left to implement

→ Read IMPLEMENTATION_SUMMARY.md "Phase Status"

Implementation Status

✅ Complete (Phase 1–3 Framework)

  • All documentation (7 comprehensive guides)
  • State machine + UI navigation
  • Exercise framework (base class + 2 implementations)
  • Dashboard controllers (tasks + activity grid)
  • Firebase service skeleton
  • Devlog modal
  • Guest login

🔲 In Progress / Planned

  • Phase 2: Implement Firebase REST calls, populate Firestore seed data
  • Phase 3: Wire up Interactable components, test hand interactions
  • Phase 4: Animations, error handling, Firebase Auth

📋 Next Steps

  1. Open Lens Studio project
  2. Follow docs/architecture.md to wire scene hierarchy
  3. Test Phase 1 acceptance criteria
  4. Implement Phase 2 Firebase calls
  5. Test Phase 2 task loading

Getting Help

I don't know where to start

→ Read QUICK_START.md (5 min)

I'm getting TypeScript errors in Lens Studio

→ Check IMPLEMENTATION_SUMMARY.md "Testing Checklist"

I want to know what a script does

→ Search file in Scripts/ folder → Look for print() log statements → Check @input fields in Inspector

I'm stuck on a specific feature

→ Check docs/phases.md for that feature's phase → Read IMPLEMENTATION_SUMMARY.md for context → Search script names in Scripts/ folder

I want to contribute

→ Read docs/architecture.md to understand structure → Follow docs/phases.md phase order → Use script comments (// Phase X:) as guides
