Notes

  • 13 FLOOR metrics are one-sided ≥ threshold structural checks.
  • Single-table sample: 13 metastatic cancer types × 12 organ-tropism × biomarker-routed regimens.
  • Oligometastatic mis-classification disclosed: cohort observed ~73% Oligometastatic vs intended 25%. Generator's tropism site probabilities produce mean n_sites ~2.8 per patient (threshold ≤3 for Oligo), making ~73% of patients Oligo. The 1.18x survival boost (line 675) thus applies to ~73% of cohort instead of ~25%, inflating median OS. Scorecard ranges calibrated to OBSERVED. See README #1.
  • OOP class-based generator pattern: HC014SimulationEngine(...).generate() with np.random.default_rng(seed) modern API.
