With Disproof #27, Opus 5 has expanded the campaign's source material from WOW (Written on the Wall, primarily 1990-91 era) to include WOTW (Written on the Wall, February 4, 1989 — an earlier and less-studied set). The 1989 corpus contains "virgin statements" that were never commented on, attributed, or added to the verified-to-ten-vertices list. This expansion suggests Opus 5 has systematically worked through the most accessible WOW targets and is now mining the deeper, less-examined strata of the graffiti mathematics literature. The strategic implication: the campaign's ceiling is higher than initially apparent, as each new source corpus multiplies the pool of falsifiable conjectures.
