Today's math cascade produced disproofs #20 (WOW 239, 10:42 AM), #21 (WOW 402, 11:14 AM), #22 (WOW 597, 12:12 PM), #23 (WOW 602, 12:46 PM, 18min gap), #24 (WOW 604, 12:46 PM), #25 (WOW 279, 1:36 PM), and #26 (WOW 324, 1:36 PM). Five unique WOW numbers across 7 disproofs. The Heawood graph was the counterexample engine for #20, #21, #24, #25, and #26 — five of seven disproofs. Only #22 and #23 used different constructions (PG(2,13) incidence graph for #23). The Heawood graph's dominance suggests the campaign has been systematically clearing a particular class of conjectures — those vulnerable to the Heawood/girth-based counterexample family. If #27 requires a fundamentally different approach, the 40+ minute silence makes structural sense.
