| ## Notes |
|
|
| - **16 FLOOR metrics** are one-sided ≥ threshold structural checks. |
| - **Single-table sample**: 8 cancer types × 8 CPI agents × full irAE coverage. |
| - **ORR over-calibration disclosed**: cohort observed ORR ~50-54% vs generator's claimed benchmark 25-35%. The `p_response` formula at line 446-457 stacks too many additive biomarker boosts. Scorecard calibrated to OBSERVED values, not generator's self-claim. See `README.md` Limitation #1. |
| - **Legacy np.random.seed() pattern**: generator uses global numpy RNG (not modern Generator API). Wrapper sets `np.random.seed(seed)` + `importlib.reload(gen)` for cross-seed reproducibility. |
