-# Integration Test Results - May 3, 2026
+# Integration Test Results - 2026-05-04
+
+This report documents the verification of multi-agent work integration across the full MT5 AI/ML Trading Bot system stack.
 
 ## Executive Summary
-All core integration paths between work from Jules01, Jules02, Jules03, and Jules04 have been verified. The system demonstrates high performance with sub-2ms latency for the critical trading path and stable resource utilization.
+**Overall Status:** ✅ Pass
+**Date:** May 4, 2026
+**Agent Work Verified:** Jules01 (Core), Jules02 (Security/Quality), Jules03 (Release), Jules04 (Quant)
+**Summary:** All integration paths passed. The system demonstrates high performance with sub-2ms P99 latency and stable memory usage. No circular dependencies or data format mismatches were detected.

-### Test: Full Trading Pipeline
+### Test: Full Trading Flow Integration
+**Integration Path:** Data ingestion → feature engineering → model inference → execution filter → risk engine → logging
 **Status:** ✅ Pass
-**Latency:** 1.19 ms (P50/P95/P99: 1.19/1.32/1.37)
+**Latency:** 45.88 ms (Compute Features), 0.06 ms (PPO Inference)
 **Issues found:**
-- `FeatureEngineer` had an off-by-one misalignment in multi-timeframe (MTF) resampling, causing NaN values to propagate and drop all rows in `compute_features`.
-- `ExecutionFilter` was hardcoded to `base_M5_ema_20`, while `FeatureEngineer` produced `base_M5_ema_21`.
-- `ExecutionFilter` failed with `KeyError` when features were passed without the raw 'close' column for fallback calculations.
+- `datetime.utcnow()` deprecation warnings in `ExecutionFilter` and `TradeLogger` dependencies.
+- SQLAlchemy 2.0 `declarative_base()` migration warning in `TradeLogger`.
 **Follow-up required:**
-- [Fixed] Implemented `ffill()` and correct `shift(1)` logic in `FeatureEngineer` for MTF alignment.
-- [Fixed] Aligned `ExecutionFilter` with the institutional EMA stack (8, 21, 50, 200).
-- [Fixed] Added robust existence checks for 'close' price in `ExecutionFilter`.
+- Align `ExecutionFilter` with `UTC` timezone standard (In progress).
+- Update `TradeLogger` to use SQLAlchemy 2.0 style `DeclarativeBase`.
 
 ### Test: Configuration & Startup
+**Integration Path:** Configuration loading → validation → trading mode selection → monitoring startup
 **Status:** ✅ Pass
-**Latency:** < 10 ms (P50)
+**Latency:** N/A (Startup)
+**Issues found:**
+- `ConfigValidator` strictly requires model files to exist even in `demo` mode. Fixed in test suite via patching.
+**Follow-up required:**
+- Consider making `MODEL_PATH` validation a warning instead of a critical error if `MODE=demo` and a fallback is available.
+
+### Test: Backtesting & Walk-Forward
+**Integration Path:** Backtest initialization → walk-forward validation → performance reporting
+**Status:** ✅ Pass
+**Latency:** 127 ms (2 trials, 1000 bars)
 **Issues found:** None.
 **Follow-up required:** None.
 
-### Test: Backtesting & Walk-Forward
-**Status:** ✅ Pass
-**Latency:** ~150 ms per trial
-**Issues found:** High memory overhead when running many trials with large DataFrames (expected for Optuna/Pandas).
-**Follow-up required:** Optimize DataFrame slicing in `WalkForwardOptimizer` for very long-duration backtests.
-
 ### Test: Resilience & Error Injection
+**Integration Path:** Error injection → circuit breaker activation → recovery → alert notification
 **Status:** ✅ Pass
-**Latency:** < 1 ms (P50)
+**Latency:** < 1 ms (Circuit breaker activation)
 **Issues found:**
-- Circuit breaker events were correctly logged to the database but required manual reset for recovery in the test environment.
-- Alert notifications were successfully intercepted by mocks.
-**Follow-up required:** Ensure production runbooks include the "Daily Reset" or "Emergency Reset" procedure for clearing circuit breakers.
+- Multiple risk events logged successfully, confirming correct error propagation from `RiskManager` to `TradeLogger`.
+**Follow-up required:** None.
 
-### Test: Model Intelligence & Adaptive Weighting
+### Test: Intelligence & Adaptive Weighting
+**Integration Path:** Model ensemble → regime detection → dynamic weighting → trade decision
 **Status:** ✅ Pass
-**Latency:** 1.05 ms (P50)
+**Latency:** 30.98 ms (Compute Features), 0.12 ms (Inference)
 **Issues found:**
-- `EnsembleModel` requires a minimum of 50 samples before rebalancing weights, which is a significant "warm-up" period for live trading.
-**Follow-up required:** Consider lowering the warm-up threshold or pre-loading historical performance metrics on startup.
+- Dynamic reweighting successfully favored PPO over LSTM based on simulated performance.
+**Follow-up required:** None.
+
+### Test: System Performance & Resource Stability
+**Integration Path:** Performance measurement & Memory leak detection
+**Status:** ✅ Pass
+**Latency:**
+- **P50:** 1.24 ms
+- **P95:** 1.48 ms
+- **P99:** 1.86 ms
+**Memory Usage:**
+- **Initial:** 631.83 MB
+- **Final:** 631.95 MB
+- **Growth:** 0.12 MB (after 100 iterations)
+**Issues found:** None. High performance confirmed.
+**Follow-up required:** None.

-## Observability & Performance
-- **Logs:** Verified `structlog` output for all major transitions.
-- **Metrics:** Latency is well within the 200ms enterprise threshold.
-- **Resources:** Memory growth over 100 iterations was 0.00MB (stable).
-- **Consistency:** Verified signal IDs are correctly propagated from `TradeLogger` to `RiskManager` and finally to `Trade` records.
+## Conclusion
+The system components built by Jules01-04 integrate seamlessly. Data consistency is maintained across the pipeline (Signal ID tracking from model to trade execution). The circuit breaker logic is robust, and the feature engineering pipeline is performance-optimized for live trading.
