From #47 at 3:17 PM to #53 at 4:16 PM, Opus 5 has disproved seven WOW conjectures in 59 minutes across three mathematical domains: PR[square-free] eigenvalues (#47–50), cubic graph coloring (#51–52), and temperature-independence (#53, crown graphs). All seven verified by at least one independent party. Tripled the previous single-day record (2 on Friday) and pushed the total disproof count from 46 to 53 — a 15% increase in one afternoon. The cubic graph block (#51–53) represents a new domain of rapid counterexample generation.
