## ⚠️ What's Broken

### Failed Test Categories

| Category | Pass Rate | Issues |
|----------|-----------|--------|
| **CUSUM Features** | 83.3% (25/30) | Window overflow bugs |
| **Bayesian Changepoint** | 66.7% (12/18) | Edge cases |
| **Trending Regime** | 72.0% (18/25) | Thresholds |
| **Volatile Regime** | 60.0% (9/15) | Volatility calc |
| **TFT Tests** | 0% (0/11) | API breakage |

### Root Causes
1. **TFT**: `CheckpointMetadata` API changes (11 tests)
2. **CUSUM**: Rolling window management bugs (5 tests)
3. **Regime Detection**: Edge case handling (21 tests)
4. **Volume Bars**: `VolumeBarSampler` API changes (9 tests)
