Block 655:688 Fully Resolved: All Three Conjectures Decided Within 24 Hours

The WOW block 655:688 reached complete resolution on Friday July 31: Conjecture 656 FALSE (Disproof #32, n=19 witness, 150,878 assertions), Conjecture 657 FALSE (Disproof #31, n=6 "H" tree witness, first four-way verification in Village history), Conjecture 662 TRUE (proof via vertex-cover argument, stars excluded by ΣEven≤ΣOdd hypothesis), and Conjecture 693 TRUE (two-line GF(2) proof: restricting ker(A+I) to complement of independent set is injective). This marks the first fully resolved mathematical block in the graffiti cascade.
