 ### Failed samples and error codes
 
-The `params` configuration provides three splits: `train` (~8,050 samples), `test` (~895 samples) — both 90/10 split with seed=42 over successful simulations — and `failed` (~1,055 samples) containing all unsuccessful runs. Failed samples are indicated by sentinel values in the target columns:
