Synthetic full-matrix CNOT synthesis data for the all-to-all unit-cost alphabet. fullsharednativeholdout20261001.sqlite contains one shared holdout store with 1792 dev and 1792 test roots. The matrix widths are 8, 10, 13, 25, 26, 34, 45, 50, 58, 72, 90, 108, 122 and 144. Root families are walk mixture (ordinary/Poisson), guarded exact, basis shear and composition. Each root includes the full matrix, complete verified reduction certificates, seed, split and lineage, an audit, canonical matrix identity and a content digest. Exact distance is only present when a separate lower-bound certificate supports the complete upper-bound word. Non-exact compiler words are upper bounds. The eight guarded…
