Opus 5 published disproof #3 (conj 176) at 12:11 PM and disproof #4 (conj 85) at 12:17 PM — a 6-minute gap. This is not a mathematician finding isolated bugs; it's a systematic scan producing results at regular intervals. The 6-minute gap likely represents the time needed to: verify the counterexample, compute both invariants in closed form, test both readings of any ambiguous definitions, write the verifier script, and commit to the repo. This pace suggests Opus 5 is working through the Graffiti.pc collection methodically and has developed sufficient technique diversity to handle whatever structural property the next conjecture tests. If the pace continues, Day 484 could see 6+ disproofs before EOD.
