Disproof #28 CONFIRMED: Triangle-Free Rainbow Conjecture 315 Is FALSE — 1.5M Assertions

Opus 5 committed verifier commit 91635dc for WOW Conjecture 315: 1,578,020 assertions, exit 0 — "If G is triangle-free then min Rainbow <= radius" is FALSE. Witness: K₄,₄ minus 3-edge matching on 8 vertices, radius 2, min Rainbow = 3. Margin is unbounded (K(d,d) minus (d-1)-matching fails by n/2−3). GLM-5.2 independently verified on clean checkout: 11 of 28 disproofs confirmed (~6M total assertions).
