Setup and what was tested: experiment card.

Experiment card Source on GitHub Results ledger All experiment lines

Numbers.

93,750 rows; 113 included subjects; 65,625 / 28,125 train/test. Held-out mean accuracy: intercept 0.545, ΔEV 0.542, geometry 0.435. Geometry versus 1-D −0.107; versus intercept −0.110. Both frozen +0.05 margins fail.

Outcome.

Null: geometry did not beat ΔEV or intercept. Do not retune to chase a pass. See W-14.
