+   - **Type**: Assertion failure
+   - **Status**: Pre-existing (Wave D validation)
+
+**Classification**: These 12 failures are **pre-existing** and documented in CLAUDE.md as known TFT model test failures. They do not represent new regressions introduced by Wave D.
+
+---
+
+### Trading Service Failures (3 total)

+
+## Pass Rate Analysis
+
+### Overall Metrics
+
+- **Total Tests**: 3,198
+- **Passed**: 3,183 (99.53%)
+- **Failed**: 15 (0.47%)
+- **Ignored**: 34 (1.06%)
+
+### Comparison to Expected Results
+
+| Metric | Expected | Actual | Delta | Status |
+|---|---|---|---|---|
+| Pass Rate | >99.0% | 99.53% | +0.53% | ✅ EXCEEDS |
+| Pre-existing TFT Failures | 12 | 12 | 0 | ✅ MATCHES |
+| New Failures | 0 | 3 | +3 | ⚠️ NEW ISSUES |
+
+### Assessment
+
+The **99.53% pass rate exceeds the 99% target**, with only 15 failures out of 3,198 tests.
+
+**However**, the 3 new Trading Service allocation test failures require attention:
+
+- These are **NOT** part of the 12 pre-existing TFT failures
+- They appear to be related to Wave D Kelly criterion and adaptive position sizing integration
+- They affect core position sizing and risk management functionality
+
+---
+
+## New Failures Root Cause Analysis
+
+### Allocation Module Failures
+
+The 3 new failures in `services/trading_service/src/allocation.rs` suggest:
+
+1. **Kelly Criterion Integration Issue** (`test_kelly_allocation`):
+   - The kelly_criterion_regime_adaptive() function may not be correctly implementing the regime-adjusted Kelly formula
+   - Test expects `weights["AAPL"] > weights["GOOGL"]` but this assertion is failing
+   - Possible cause: Incorrect regime multiplier application (0.2x-1.5x range)
+
+2. **Leverage Constraint Validation** (`test_leverage_constraint`):
+   - Test expects `result.is_err()` for over-leveraged positions but validation is passing when it should fail
+   - Possible cause: Leverage constraint checks not properly integrated with adaptive position sizing
+
+3. **Position Size Constraint** (`test_apply_constraints`):
+   - Test expects `constrained["AAPL"] <= constraints.max_position_size` but constraint is not being applied
+   - Possible cause: max_position_size constraint not being enforced after regime-adaptive sizing
+
+### Recommended Actions
+
+1. **Immediate (2-3 hours)**:
+   - Investigate kelly_criterion_regime_adaptive() implementation in `services/trading_service/src/allocation.rs`
+   - Verify regime multiplier application (0.2x-1.5x range)
+   - Validate leverage constraint checks are integrated with adaptive position sizing
+   - Fix position size constraint enforcement
+
+2. **Validation (1 hour)**:
+   - Re-run failing tests: `cargo test -p trading_service allocation::tests`
+   - Verify all 3 tests pass
+   - Run full test suite again to confirm no regressions
+
+---
+
+## Compilation Warnings
+
+### Summary
+
+The test suite generated **minimal warnings** during compilation:
+
+- **model_loader**: 2 warnings (unused extern crates: `chrono`, `tokio`)
+- **trading_engine**: 1 warning (unused variable `event`)
+- **api_gateway**: 4 warnings (unused OCSP imports, unused method `put`)
+- **ml**: 24 warnings (missing Debug implementations, unused variables)
+- **backtesting_service**: 4 warnings (unused imports, unused fields)
+- **ml_training_service**: 2 warnings (unused imports, unused variables)
+- **trading_service**: 1 warning (useless comparison due to type limits)
+- **trading_agent_service**: 2 warnings (unused fields)
+
+**Assessment**: These warnings are **non-blocking** and do not affect test execution or system functionality. They can be addressed in a future code quality cleanup wave.
+
+---
+
+## Test Execution Performance
+
+- **Compilation Time**: 12m 07s
+- **Total Execution Time**: ~2 minutes
+- **Longest Test Suite**: data (30.02s)
+- **Average Test Suite**: <1s per package
+
+**Assessment**: Test execution performance is excellent, with most test suites completing in under 1 second.
+
+---
+
+## Validation Criteria
+
+| Criterion | Target | Actual | Status |
+|---|---|---|---|
+| Overall Pass Rate | ≥99.0% | 99.53% | ✅ PASS |
+| Pre-existing TFT Failures | 12 | 12 | ✅ EXPECTED |
+| New Wave D Failures | 0 | 3 | ⚠️ 3 NEW |
+| Critical Test Failures | 0 | 0 | ✅ PASS |
+| Compilation Errors | 0 | 0 | ✅ PASS |
+
+**Overall Status**: ✅ **CONDITIONAL PASS**
+
+- Pass rate exceeds target (99.53% > 99%)
+- Pre-existing failures match expectations (12 TFT failures)
+- **BUT**: 3 new allocation test failures require fixes before production deployment
+
+---
+
+## Recommendations
+
+### Immediate Actions (2-4 hours)
+
+1. **Fix Allocation Test Failures** (Priority: HIGH)
+   - Investigate kelly_criterion_regime_adaptive() in `services/trading_service/src/allocation.rs`
+   - Verify regime multiplier application (0.2x-1.5x)
+   - Fix leverage constraint validation
+   - Fix position size constraint enforcement
+   - Re-run tests to confirm fixes
+
+2. **Update CLAUDE.md**:
+   - Document 3 new allocation test failures
+   - Update test pass rate from 99.4% (2,062/2,074) to 99.53% (3,183/3,198)
+   - Reflect completion of Validation 8/8
+
+### Follow-up Actions (1-2 days)
+
+1. **TFT Model Test Investigation**:
+   - 12 pre-existing TFT failures need root cause analysis
+   - Determine if these are test issues or model implementation issues
+   - Create action plan for TFT test stabilization
+
+2. **Code Quality Cleanup**:
+   - Address compilation warnings (unused imports, unused variables)
+   - Add missing Debug implementations to ML structs
+   - Clean up unused code (extern crates, fields, methods)
+
