#### 🔍 Failure Analysis

**Root Cause #1: Missing Test Data** (3 failures)
```
Error: Failed to read directory: "test_data/real/databento"
Caused by: No such file or directory (os error 2)
```
- **Impact**: Low - Tests expect `test_data/real/databento` directory
- **Fix**: Create test data fixtures or skip tests when data unavailable
- **Workaround**: Tests pass when real DBN data is present

**Root Cause #2: Statistical Tolerance** (3 failures)
- Gradient norm calculations, outlier detection thresholds
- **Impact**: Low - Edge cases in benchmark validation logic
- **Fix**: Adjust numerical tolerances for floating-point precision

**Root Cause #3: Assertion Logic** (4 failures)
- Model weight adjustment, performance tracker, anomaly detection
- **Impact**: Medium - Business logic assertions need refinement
- **Fix**: Review test expectations vs actual behavior

#### 🟢 Ignored Tests (14 tests)
- Integration tests requiring external services (Redis, MinIO)
- Performance benchmarks requiring specific hardware
- Tests marked `#[ignore]` for manual execution

```bash
# Fix function signature mismatches
vim services/trading_service/tests/integration_e2e_tests.rs
vim services/trading_service/tests/rollback_automation_tests.rs

# Expected fixes:
# - Update function calls to include missing arguments
# - Fix field visibility issues in RollbackAutomation
```

#### Priority 2: Create Test Data Fixtures (30 min)
```bash
# Create test data directory structure
mkdir -p test_data/real/databento

# Copy sample DBN files or create minimal fixtures
cp test_data/ES.FUT_sample.dbn test_data/real/databento/

# Or add conditional skipping to tests
#[cfg_attr(not(feature = "real_data_tests"), ignore)]
```

#### Priority 3: Investigate ML Test Failures (2-4 hours)
Focus on 10 failing tests:
1. **Statistical tests**: Review tolerance values
