# Picks that change with the learned family

Old = `CHAMELEON_LEARNED=0`, new = with `engine/models/layout.npz` and the admission guard (`TUNABLES['learned']['guard_px']`, `guard_util`). '(critic)' = moved by the judge-distilled critic. Scores are the rule score of the shipped layout; `min px` = smallest text; `below` = texts below their readability floor. Rows in the order samples, synthetic, holdout; generated by `tools/crello/layout_picks.py`.
97 picks change to a `learned` layout, 0 to another layout.
