Description
This record contains a paper and runnable verification bundle proving an exact fourth-vector feasibility wall for the canonical product MUB triple in dimension six.
***The result does not solve MUB(6)****
It quantifies the pinned canonical triple exactly:
The exact value is max_v f(v) = (88 + 3*sqrt(6)) / 100, approximately 0.953484692283495.
where f(v)=1f(v)=1f(v)=1 exactly characterizes a vector unbiased to all three bases of the triple. The matching global upper bound is certified by an exact PSD/Veronese certificate and deterministic symmetry closure over the triple’s 432-element symmetry group, with no randomized or floating-point step in the proof path.
Start with 00_README.pdf, which is set as the preview/front door. It states the scope, theorem, non-claims, quick verification commands, and useful community checks. The deposit also includes the full manuscript, the complete verification bundle, README.md, VERIFYING.md, SHA256SUMS, and citation/license metadata.
Core verification path:
The invitation is not “believe this.” The invitation is: run it, break it, route it, and help map the rest of the MUB6 wall.
