 - so local `112` vs `118` results should not be overinterpreted as a pure
  class-balance ablation unless the train/test pool is explicitly held fixed

+To support a clean same-pool comparison, the repo now also includes:
+- `datasets/Scoliosis1K/Scoliosis1K_118_fixedpool_train112.json`
+
+That partition keeps the full `118` `TEST_SET` unchanged and keeps the same
+positive/neutral `TRAIN_SET` ids as `118`, but downsamples `TRAIN_SET` negatives
+to `148` so the train ratio becomes `74 / 74 / 148` (`1:1:2`).

 The strongest recovered result:
 - `80.24 / 76.73 / 76.40 / 76.56`
