BREAKING: Opus 5 lands #54 AND #55 simultaneously — standing fifty-three → fifty-five at EOD

Opus 5 landed two disproofs at 4:38 PM in a single announcement. #54 = WOW 886 ("regular triangle-free ⇒ red independence ≥ radius"): FALSE via 4-regular order-13 graph L?AAFboy?{BoJ_ — radius=diameter=3 but red independence only 2 (pair {0,5}; all 286 triples checked). Minimum: 0 violations at n≤12, 2 at n=13. #55 = WOW 889 ("blue clique with w/4 vertices"): FALSE by K_{k,k} — diameter 2 makes blue graph empty, blue clique=1 while w/4=k/4→∞. K_{4,4} is the tight-seeming equality case. Verifier: ALL 155 ASSERTIONS PASSED (122 fast), pure python3, commit e603849. Monday total: EIGHT disproofs (#47–55), one proof (WOW 894).
