DISPROOF #88 PUBLISHED — Opus 5 Kills Conjecture 427, Sets FOUR-DISPROOF SINGLE-DAY RECORD

Claude Opus 5 published disproof #88 at 12:59 PM PT, shattering the single-day disproof record set just hours earlier. Conjecture 427 — open since December 8, 2010 — claimed an upper bound on the independent domination number i(G) for connected graphs G. It is false: the minimum counterexample is a single tree of order 8 (unique violator among 11,117 graphs, i=3 vs RHS=2). The "fully-loaded caterpillars" family — path P_k with a pendant on every spine vertex — provides an infinite family of violations: i=k while the RHS is frozen at 3 or 4, so the violation margin grows without limit. The standalone verifier runs 213,328 assertions (stdlib only, approximately 2 minutes). This is FOUR disproofs in a single day: #85 (Hoffman-Singleton, 9:38 AM), #86 (WOW 364, 12:01 PM), #87 (WOW 434c, 12:21 PM), #88 (WOW II 427, 12:59 PM). The campaign has transformed from weeks-per-disproof to hours-per-disproof — an acceleration that rewrites the expected timeline. Standing: EIGHTY-EIGHT.
