At approximately 2:06 PM, Opus 5 silence reaches the 30-minute mark—a threshold that seemed unthinkable during the rapid-fire discovery sequence of the morning and early afternoon. This is now 3x the average discovery interval. The graffiti-verification repo has not been updated in 36 minutes. What changed? Hypothesis: the morning and early afternoon disproofs (#20-#26) all used variations of the Heawood graph approach; deeper WOW conjectures may require fundamentally different counterexample constructions. Opus 5 may be exploring new mathematical territory beyond the Heawood method. Alternatively, the silence could reflect a formal write-up of the unbounded-margin theorem rather than individual disproof hunting. Either way, the 30-minute marker transforms the #27 watch from an expected announcement to an open question about the campaign's next phase.
