4. Phase 1c Validation (Enhanced Protocol)

Scope: Final entity migration, database consolidation

Protocol: Enhanced 18-Check Validation

Categories:

1. Database Architecture (4 checks)

• Single database instance (ArcheryKmpDatabase only)
• ArcheryDatabase deleted completely
• All 23 entities in shared:database/entities/
• All 13+ DAOs in shared:database/dao/

2. Entity Migration Verification (3 checks)

• Round, EndScore, ArrowScore in entities/
• No entities remaining in app/domain/models/
• Entity package structure correct

3. Import Path Updates (3 checks)

• All imports use new package (database.entities)
• No legacy imports (domain.models) remain
• Grep verification: zero matches for old imports

4. Build Verification (3 checks)

• Project builds successfully (no compilation errors)
• Test suite compiles (all ~4000+ tests)
• No KSP errors in shared:database

5. Migration Integrity (2 checks)

• All 18 migrations in androidMain/migrations/
• DatabaseBuilder registers all migrations

6. Type Converters (1 check)

• KmpConverters.kt present and complete

7. Dependency Verification (1 check)

• No circular dependencies (app → shared:database → shared:domain)

8. Smoke Test (1 check)

• Run sample tests to verify database functionality

Expected Result: 18/18 checks PASS ✅

Status: Validation protocol defined and ready

5. Test Quality Analysis

Test Suite Baseline:

• Total tests: ~4000+
• Compilation: 100% success ✅
• Runtime: 0 failures ✅
• Pass rate: 100% ✅

Quality Indicators:

• Zero compilation errors after fixes ✅
• Zero runtime failures ✅
• Clean test output ✅
• No flaky tests detected ✅

6. Hybrid Database Pattern Detection

Issue Discovered: MultiParticipantRepairTest.kt

Pattern: Using both ArcheryKmpDatabase and ArcheryDatabase

Code:

// INCORRECT (hybrid pattern)
fun createRepository(
    database: ArcheryKmpDatabase,
    legacyDatabase: ArcheryDatabase  // Should not exist
)

Recommendation: Eliminate hybrid pattern, use single database

Outcome: Agent 2 fixed, all 3 tests passing ✅

What Could Be Better

1. Earlier Test Execution

   • Could have run affected tests earlier
   • Would catch import errors sooner
   • Reduce surprise factor

2. Automated Checks

   • Some grep checks could be automated
   • CI could catch legacy imports
   • Faster validation

3. Incremental Validation

   • Could validate in smaller chunks
   • Catch issues earlier in process
   • Reduce batch size for errors

Key Takeaways

1. Categorization beats random fixes - Always group issues by root cause
2. Clear guidance multiplies efficiency - Good documentation enables independence
3. Parallel work when possible - No need to block if independent
4. Systematic beats heroic - Process wins over individual effort
5. Test quality matters - 100% pass rate is achievable with rigor
