Current TODO List & Project Status
Last Updated: October 4, 2025 Current Phase: Phase 3 - Cache Monitoring + Phase 5.2 Polish
Recent Accomplishments (Since Sept 30, 2025)
Phase 2: Smart Caching System - COMPLETE ✅
- 5-10x faster load times for cached tournament data
- 50-90% reduction in Firestore reads
- 100% cache hit rate validated on second load
- Feature flags enabled for safe production deployment
- Automatic cache maintenance working correctly
Critical Bug Fixes - COMPLETE ✅
- ✅ Round completion sync: Network devices now see completion status properly
- ✅ Score summary data: Completed rounds display correct scores
- ✅ Guest ownership indicators: Only owner sees “Yours” badge
- ✅ Non-participant viewing: Tournament results accessible to all users
- ✅ Navigation loops: Clean back button behavior implemented
Current Project State
What’s Working Perfectly ✅
- Real-time score synchronization across devices (1-2 second latency)
- Multi-device concurrent scoring (no conflicts or data loss)
- Guest participant synchronization
- Offline score queueing and background sync
- Live leaderboard with animations and highlighting
- Network status indicators
- Firebase transaction-based atomic updates
- Smart caching with status-aware TTL
- Round completion status propagation
- Guest ownership indicators
- Non-participant tournament viewing
What Needs Attention 🔧
- Leaderboard sorting consistency - Needs review across devices
- Firestore cascade delete - Orphaned data cleanup
- Average score calculation - Shows 0.0 in some cases
- Several UX polish items cataloged below
CURRENT TODO LIST
🔴 HIGH PRIORITY (Next 1-2 Sessions)
1. Review Leaderboard Sorting Consistency Across Devices
Priority: HIGH | Effort: 0.5-1 session | Status: Needs verification
Current Behavior:
- User reports potential inconsistency in sort order across devices
- Need to verify if issue still exists after recent fixes
Expected Behavior:
- All participants sorted by score (highest to lowest) on all devices
- Consistent ordering regardless of which device is viewing
- Optional: Outline/highlight for local (scorable) participants
Technical Details:
- Impact: High if confirmed - breaks fair competition display
- Files to investigate:
- Leaderboard UI component (sorting logic)
- Participant list rendering
- Score-based sorting implementation
- Action: Test multi-device scenario first, then fix if needed
2. Implement Firestore Cascade Delete for Rounds
Priority: HIGH | Effort: 0.5 session | Status: Not started
Current Behavior:
- Deleting a round doesn’t remove the Firestore subcollection entry
- Firebase data accumulates as orphaned entries
- Potential cost implications with growing data
Expected Behavior:
- When creator deletes round, all Firebase data removed
- Subcollections cleaned up (scores, ends, participant progress)
- No orphaned data remaining
Technical Details:
- Impact: High - Firebase cost, data hygiene, potential bugs
- Files to investigate:
FirebaseTournamentRepository.kt- delete operationsHybridTournamentRepository.kt- orchestration- Round deletion flow
- Implementation: Recursive subcollection delete or batch operation
🟡 MEDIUM PRIORITY (UX & Polish - 2-3 Sessions)
3. Fix Average Score Calculation Showing 0.0
Priority: MEDIUM | Effort: 0.5 session
Current Behavior:
- “Avg” field on LiveLeaderboardCard displays 0.0 for some participants
- Averages not calculated or not displayed in all cases
Expected Behavior:
- Calculate and display average score per end
- Show accurate average for each participant
- Update in real-time as scores are submitted
Technical Details:
- Files to investigate:
LeaderboardEntry.kt- data model- Leaderboard calculation/aggregation logic
- Calculation: Total score ÷ number of ends completed
4. Lock Network Participant Selection to Prevent Orphaning User
Priority: MEDIUM | Effort: 0.5 session
Current Behavior:
- Tapping a non-local participant may deselect current participant
- User left unable to score (no participant selected)
Expected Behavior:
- Disable tap interaction for network participants (non-scorable)
- Add TODO comment for future stats feature
- User maintains their scoring context
5. Fix Participant Indicator (*) Showing for All Participants
Priority: MEDIUM | Effort: 0.5 session
Current Behavior:
- All participant cards display * indicator
- No distinction between local and network participants
Expected Behavior:
- Only local participants (scorable on this device) should show *
- Network participants should not show indicator
- Clear visual distinction of who can be scored
6. Improve 3-Letter Name Truncation Disambiguation
Priority: MEDIUM | Effort: 0.5 session
Current Behavior:
- Names truncated to 3 letters
- Creates ambiguity: “GUE” for both “Guest” and “Guest2”
Expected Behavior:
- Better disambiguation strategy for similar names
- Options:
- Use numbers when collision detected (GU1, GU2)
- Show more characters when names collide
- Full name with ellipsis for long names
7. Fix Completed Rounds Vanishing from Tournament Discovery
Priority: MEDIUM | Effort: 0.5 session
Current Behavior:
- When round is completed, it may disappear from tournament list
- Users lose easy access to completed tournament data
Expected Behavior:
- Move completed rounds to separate “Completed” tab
- Don’t hide rounds automatically
- Only hide when explicitly deleted by user
🟢 LOW PRIORITY (Future Enhancement)
8. LiveLeaderboardCard Scrollability
Priority: LOW | Effort: 0.5 session
Current Behavior:
- LiveLeaderboardCard may extend infinitely downward with many participants
- No maximum height constraint
Expected Behavior:
- Show maximum 5 participants in card
- Require vertical scroll for additional participants
- Maintain compact, manageable UI
🔵 PHASE 3: CACHE MONITORING (Next Week)
9. Production Cache Metrics Monitoring
Priority: HIGH | Effort: 1 week observation
Monitoring Tasks:
- Track cache hit rates across diverse tournaments (target: >70%)
- Validate no memory leaks or performance issues
- Analyze Firestore read reduction in real usage (expecting 50-90%)
- Tune TTL settings if needed based on user behavior
- Consider adding manual refresh UI (pull-to-refresh gesture)
Success Criteria:
- ✅ Cache hit rate >70% across diverse tournaments
- ✅ Memory usage stable, no leaks
- ✅ Firestore costs reduced by 50-90%
- ✅ Consistent 5-10x performance improvement
- ✅ No user complaints about stale data
🔵 DEFERRED (Future Sessions)
10. Validate Offline → Online Transition Behavior
Priority: DEFERRED | Effort: 1 session
Scope:
- Test score sync when device comes back online
- Validate queued scores are submitted correctly
- Verify no data loss during transition
- Test multiple devices going offline/online
11. Test Conflict Resolution Edge Cases and Performance
Priority: DEFERRED | Effort: 1 session
Scope:
- Test simultaneous end completion from multiple devices
- Validate with 10+ concurrent participants
- Performance testing under load
- Edge case scenario validation
🧹 CLEANUP
12. Remove Debug Log Markers from Tournament Sync Code
Priority: LOW (after validation) | Effort: 0.5 session
Scope:
- Remove or reduce verbose diagnostic logging added during development
- Keep essential error logging
- Clean up temporary debug markers (📸, 🔄, ✅, etc.)
- Production-ready logging levels
Files with debug logging:
LiveScoringViewModel.kt- RecordEndCompletion, ParticipantProgress tagsFirebaseTournamentRepository.kt- TournamentScoreSync, detailed logsHybridTournamentRepository.kt- various sync operation logs

Session Resume Checklist
When resuming:
- ✅ Review this TODO file (you’re doing it now!)
- ⬜ Check current cache system status - ensure flags still enabled
- ⬜ Review “What’s Working” section - don’t break these
- ⬜ Start with Phase 3 cache monitoring setup
- ⬜ Address high-priority items (leaderboard, cascade delete)
- ⬜ Update this file as tasks complete
- ⬜ Mark items complete: Change ⬜ to ✅
BOTTOM LINE: Core tournament scoring is production-ready with excellent real-time sync and smart caching working perfectly. Phase 3 cache monitoring should begin immediately. Remaining polish items are well-cataloged with clear 3-session roadmap (6 hours) to full production deployment.
