IMMEDIATE ACTIONS (Agent 19)
-----------------------------

1. FIX BUFFER CAPACITY (30 min):
   - trading_service: 6 tests failing on buffer sizes
   - Change: 1000→1024, 500→512, etc.

   - Review update_unrealized_pnl() logic
   - File: position_manager.rs

4. ENABLE DB TESTS (30 min):
   - ml_training_service: 2 tests ignored
   - Add test database fixtures

PHASE 2: INTEGRATION TESTS (1 week)
------------------------------------

Trading Service (2 days):
- Order submission → execution → position update
- Market data → strategy signal → order
- Target: 30% → 60% coverage

Backtesting Service (2 days):
- Strategy engine execution tests
- Performance calculation tests
- Target: 3% → 50% coverage

ML Training Service (2 days):
- Training loop tests
- Model evaluation tests
- Target: 2% → 40% coverage

PHASE 3: CRITICAL PATHS (2 weeks)
----------------------------------

Trading Service:
- RiskManager: 8% → 80% (VaR, limits, breakers)
- AuthInterceptor: 7% → 85% (JWT, revocation, RBAC)
- BrokerRouting: 2% → 70% (latency, failover)

COVERAGE BLOCKERS RESOLVED
---------------------------
✅ cargo-llvm-cov: Installed and working
✅ Compilation: Fixed in Phase 1
✅ Migrations: All 17 applied successfully

TIMELINE
--------
- Phase 1 (1-2 days): Fix test failures → Re-measure
- Phase 2 (1 week): Integration tests → 40-60%
- Phase 3 (2 weeks): Critical paths → 70-85%

TOTAL: 3-4 weeks to production-ready coverage

STATUS: ⚠️ MEASUREMENT INCOMPLETE - Fix 15 test failures first
