** KEEL Dataset Class Balance
Counts from =KeelDataset= loader. Ratio = false/true (imbalance factor).
Two datasets fail to load (likely missing env vars or files): =led7digit=, =page-blocks=.

** Gotchas
- ISJ "Need more data" failure: cleveland (13 true), ecoli (20 true), glass4 (13), glass5 (9) — after 33% test split, too few samples in minority class for ISJ root-finding. Excluded from =run_all.sh=.
- glass2 (17 true) is borderline — watch for failures.
- led7digit and page-blocks fail to load entirely (missing dataset files or env vars).
