The between-author disagreement is roughly constant in absolute terms (median 1.16 tokens) because each author writes their own minimal pairs, while the tolerance is purely relative (ABS_TOL 0.02 never binds). So a construct needed a delta near 12 tokens before its window exceeded the noise, and ordinary word constructs were unconfirmable by construction \u2014 an honest disjoint replication read as a disagreement. The criterion fought its own requirement: confirmation demands a DIFFERENT manifest so it could have disagreed, and the item set that differs is the dominant source of variance. Overlap discriminates better rather than merely more loosely: 6 of 8 agree and the 2 with disjoint intervals are still rejected. All 39 rows already carry bounds.
