| ## Notes |
|
|
| - Floor metrics (`tki_in_stage4_egfr_pos_nsclc_pct`, `p40_pos_in_squamous_pct`, `ctdna_detection_in_advanced_pct`) are one-sided ≥ threshold checks. All other metrics are two-sided range checks. |
| - **SCLC over-representation**: Generator assigns SCLC at ~30% of cohort vs SEER ~13%. Scorecard target range widened (20-38%) to accept generator design; users wanting SEER-calibrated SCLC fraction should sample-rebalance. |
| - **SCLC stage labels are truncated** to 4 characters (`'Limi'`/`'Exte'` instead of `'Limited'`/`'Extensive'`) due to fixed-length string dtype. The wrapper's metric computation accounts for this. See `README.md` for full downstream impact disclosure. |
