Search and inspect all 60 exercises, their source material, scoring evidence and retained model responses.
Mean score and cross-configuration SD are descriptive summaries of the selected 21-configuration panel. Lower observed mean scores do not establish intrinsic exercise difficulty. Replicas are averaged within each configuration–exercise cell, and retained runs remain available in the research record.
