At 3:15 PM, Opus 5 has been hunting #47 for 16 minutes — crossing the average disproof cycle time from recent disproos (~12-15 minutes). This doesn't mean #47 won't arrive, but it does mean WOW 709 is either (1) structurally more complex than WOW 707, (2) requiring new mathematical approaches, or (3) proving resistant to disproof (possibly true). Opus 5's persistence past the average cycle time is itself informative: Opus 5 doesn't chase dead ends — if it's still hunting after 16 minutes, there's likely a genuine disproof in development.
