Total Week 12: 7 DAOs migrated (1,856 lines, 159 methods)
Critical Issues Resolved
DEX Blocker (Day 0-2):
- Issue: DEX limit exceeded (75,742 methods)
- Root Cause: Week 11 pattern not followed
- Fix: Restored Week 11 pattern (comment entities in ArcheryAppDatabase)
- Result: DEX count reduced to ~65K methods
Default Parameter Anti-Pattern (P0):
- Issue: Default parameters with
Clock.System.now()evaluate once at class load - Impact: Stale timestamps break cache validity and audit trails
- Found in: EquipmentStatsDao (6 methods), RoundDao (1 method)
- Fix: Remove default parameters, force explicit timestamps at call sites
- Prevention: Enhanced semantic validation protocol (Agent 3)
Enhanced Validation Protocol Success
New Protocol Implemented:
- Semantic code review checklist (default parameters, cache logic, time-sensitive ops)
- Added to Agent 3’s validation workflow (mandatory step)
Effectiveness Demonstrated:
- Day 0-2: Missed EquipmentStatsDao bug (no protocol)
- Day 3-5: Caught RoundDao bug immediately (with protocol)
- Recommendation: Make mandatory for all future DAO/service migrations

Week 11 + 12 Combined Progress
Total Progress: 19 of 19 DAOs (100%) ✅
Quality Metrics:
- Tests Passing: 4,090 (100% pass rate)
- Coverage: 81%+ maintained
- Code Quality: ⭐⭐⭐⭐⭐ (Agent 1 + Agent 3 validation)
- KMP Compatibility: Zero Android dependencies
- Build Success: All builds passing (shared:database, assembleDebug, assembleRelease)
Migration Pattern:
- Create entity in shared:database
- Create DAO interface in shared:database
- Implement DAO in shared:database
- Comment out entity in ArcheryAppDatabase (androidApp)
- Update ArcheryKmpDatabase (shared:database)
- Run tests (4,090 tests must pass)
- Agent 3 validation (architectural + semantic review)
Deferred:
- OfflineScoreQueueDao: JVM-specific, currently disabled in codebase
- Will be addressed in future KMP work if needed
Next Phase: Week 13-14 Database Cutover
Goal: Activate ArcheryKmpDatabase, retire ArcheryAppDatabase
Status: Ready to plan (all DAOs migrated)
Prerequisites:
- ✅ All 19 DAOs migrated to shared:database
- ✅ All entities migrated to shared:database
- ✅ Week 11 pattern validated (entities commented)
- ✅ KMP compatibility verified
- ✅ Zero test failures
Remaining Work:
- Update AndroidApp to use ArcheryKmpDatabase instead of ArcheryAppDatabase
- Remove ArcheryAppDatabase
- Verify all 4,090 tests still pass
- Agent 3 validation
Estimated Effort: 1-2 days
Key Learnings
Week 11 Pattern Critical
Pattern: Comment out entities in ArcheryAppDatabase when migrating to shared:database
Why Critical:
- Prevents DEX limit issues (duplicate entity definitions)
- Maintains build stability during migration
- Clean separation between old and new database
Week 12 Day 0-2 Incident:
- Deviated from Week 11 pattern → DEX blocker
- Restored pattern → build success
- Lesson: Always follow established migration patterns
Default Parameter Anti-Pattern (P0)
Issue:
// BAD - evaluates ONCE at class load!
fun query(timestamp: Long = Clock.System.now().toEpochMilliseconds())
// GOOD - evaluate at call site
fun query(timestamp: Long)
// Call site:
dao.query(Clock.System.now().toEpochMilliseconds())Impact:
- Cache validity checks broken (stale timestamps)
- Audit trails incorrect (all updates same timestamp)
- Silent failures (logic appears to work, but uses wrong values)
Prevention:
- Agent 3’s enhanced semantic validation protocol
- Code review checklist for time-sensitive operations
- Mandatory for all future migrations
Enhanced Validation Protocol Success
Effectiveness:
- Caught RoundDao bug immediately (Day 3-5)
- Would have caught EquipmentStatsDao bug if applied earlier
- Recommendation: Make semantic validation mandatory for all future DAO/service migrations
Protocol Components:
- Architectural review (Agent 1)
- Test validation (Agent 3)
- NEW: Semantic code review checklist (Agent 3)
- Default parameters with time-sensitive values
- Cache logic correctness
- Timestamp handling
- KMP compatibility
