Direct-remainder components pass their controls
All 13 controls pass. The study uses its 18 bound calls, eight rotation steps, 376 fixed grid/axis probes and 22 independent rational reference calls. It covers calibration denominators, packet-boundary clipping, shared-parameter products and noncommuting rotations about zero and nonzero references.
The first freeze preserves 11 completed checks and two checks that did not execute because of aggregate charging. Version 2 corrects only that wrapper; the mathematical code and independent references are unchanged.
The next requirement is a certified derivative at the source reference point. The direct bound concerns an ideal first-order expansion; the actual native center and coefficient rows need explicit error allowances. A floating Jacobian agreement tolerance cannot replace that bridge. Installation, full-history usefulness and recording-scale uncertainty remain unqualified.
