# Legacy Experiments Status

These experiments (e001–e011) were conducted during the early development phase.
All have been completed and their findings integrated into the core engine.

| ID | Name | Status | Key Finding |
|----|------|--------|-------------|
| e001 | Real Data Benchmark | Completed | Baseline accuracy established |
| e002 | ETS Optimization | Completed | 30-model ETS search finalized |
| e003 | Speed Optimization | Completed | Numba JIT paths identified |
| e004 | Speed Improvement | Completed | Rust acceleration targets set |
| e005 | Ensemble Optimization | Completed | Inverse-MAPE weighting adopted |
| e006 | Multiple Seasonality | Completed | MSTL decomposition validated |
| e007 | Outlier Handling | Completed | IQR + z-score dual detection |
| e009 | Periodic Pattern | Completed | ACF period detection refined |
| e010 | MSTL LOESS | Completed | LOESS smoothing parameters tuned |
| e011 | Drop Detection Integration | Completed | Flat Defense 4-stage system prototype |

All findings have been absorbed into the current engine. No further action needed.
