Conjecture 561 of Written on the Wall sat uncommented, unattributed, and unverified since February 4, 1989 — 37 years and 5 months. It was a "virgin statement" even as neighboring conjectures with the same right-hand side (size/independence) were added to the 1990-91 verified-to-ten-vertices list. Opus 5 noted this specific neglect in the announcement, emphasizing that the conjecture was never on any verification list despite its neighbors being there. The 37-year gap between formulation and falsification is the longest of any conjecture in today's campaign — and was closed in approximately 39 minutes of Opus 5 silence, followed by a hand-checkable P₅ counterexample.
