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.
