🎯 REMEDIATION ROADMAP
═══════════════════════════════════════════════════════════════════════════════

PHASE 1: Common Crate (Priority: CRITICAL)
├─ Target: 22.75% → 80%+
├─ Files: error.rs, trading.rs, database.rs, traits.rs
├─ Tests: ~150 new tests
├─ LOC: ~400 test lines
├─ Time: 2-3 hours
└─ Impact: Fixes ALL foundational error handling + trading types

PHASE 2: Storage S3 Backend (Priority: CRITICAL)  
├─ Target: 9.92% → 85%+
├─ Files: object_store_backend.rs, model_helpers.rs
├─ Tests: ~80 new tests (requires S3 mocking)
├─ LOC: ~300 test lines
├─ Time: 2 hours
└─ Impact: Validates production model storage

PHASE 3: Config Completeness (Priority: MEDIUM)
├─ Target: 57.96% → 75%+
├─ Files: ml_config, data_config, storage_config, structures, schemas
├─ Tests: ~100 new tests
├─ LOC: ~350 test lines
├─ Time: 2 hours
└─ Impact: Startup configuration validation

TOTAL: 330 tests, ~1050 LOC, 6-7 hours

EXPECTED FINAL COVERAGE:
   common:  80%+ (up from 22.75%)
   config:  75%+ (up from 57.96%)
   storage: 85%+ (up from 81.87%, fixing S3 gap)

🔄 NEXT STEPS
═══════════════════════════════════════════════════════════════════════════════

Immediate (Agent 9+):
   □ Measure service-level coverage (api_gateway, trading_service, etc.)
   □ Aggregate workspace-wide coverage metrics
   □ Compare to Wave 111 baseline (42.6%)

Short-term (Post Wave 112):
   □ Implement Phase 1: Common crate tests (2-3 hours)
   □ Implement Phase 2: Storage S3 tests (2 hours)
   □ Implement Phase 3: Config completeness (2 hours)
   □ Re-measure to validate 80%+ foundational coverage

Long-term:
   □ E2E tests exercising all crates together
   □ Performance benchmarks for common types
   □ Integration tests for S3 storage backend
