Failed Test Analysis

Single Failure: tli::auth::key_manager::tests::test_env_key_derivation

Root Cause: This test requires Vault connection for token encryption validation. It's a known, acceptable failure documented in AGENT_FIX10_TLI_TOKEN_ENCRYPTION.md.

Impact: Non-blocking. Token encryption works in production with Vault. This is a test environment limitation.

Resolution: Already documented, no production impact.

Improvements Since Last Audit

• Trading Agent Service: 77.4% → 100% (+29% improvement, 12 tests fixed)
• Trading Engine: 96.7% → 100% (+3.4% improvement, 11 tests fixed)
• Overall: 99.4% → 99.97% (+0.57% improvement)

Verdict: ✅ PASS - 99.97% pass rate exceeds 99.5% target.

9. Blockers Resolved Status ⚠️

BLOCKER 1: Adaptive Position Sizer Integration

Status: ⚠️ NOT RESOLVED (8 hours estimated)

Issue: The following functions are NOT implemented in trading_agent_service:

• kelly_criterion_regime_adaptive() - Regime-adaptive position sizing using Kelly Criterion
• calculate_regime_adaptive_stop() - Regime-adaptive dynamic stop-loss calculation

Impact:

• Wave D regime-adaptive position sizing is not wired into the Trading Agent
• Sharpe improvement hypothesis (+33%) cannot be validated in production
• Adaptive stop-loss multipliers (1.5x-4.0x ATR) not applied

Files Affected:

• /home/jgrusewski/Work/foxhunt/services/trading_agent_service/src/allocation.rs
• /home/jgrusewski/Work/foxhunt/services/trading_agent_service/src/orders.rs

Resolution Required: Implement missing functions and wire them into decision flow

---

BLOCKER 2: Database Persistence Deployment

Status: ⚠️ NOT RESOLVED (70 minutes estimated)

Issue:

1. Migration 046 conflict with migration 045
2. Module regime_persistence not exported from common crate
3. SQLX metadata stale (requires cargo sqlx prepare)

Impact:

• Regime states not persisted to database during live trading
• Regime transitions not logged for historical analysis
• Adaptive strategy metrics not tracked

Files Affected:

• /home/jgrusewski/Work/foxhunt/migrations/046_rollback_regime_detection.sql
• /home/jgrusewski/Work/foxhunt/common/src/lib.rs
• /home/jgrusewski/Work/foxhunt/services/trading_agent_service/.sqlx/

Resolution Required:

1. Delete migration 046
2. Export regime_persistence module
3. Run cargo sqlx prepare --workspace

---

Post-Resolution Validation Checklist

After both blockers are resolved:

• Run full test suite: cargo test --workspace --lib --no-fail-fast
• Verify Adaptive Sizer integration: cargo test -p trading_agent_service --lib test_kelly_regime_adaptive
• Verify Database Persistence: cargo test -p trading_agent_service --lib test_regime_persistence_roundtrip
• Run Wave D backtest: cargo test -p backtesting_service --test integration_wave_d_backtest
• Validate gRPC endpoints: Test GetRegimeState and GetRegimeTransitions
• Final smoke test: Run 5-minute paper trading session
