Common reference-acceleration controls

18/18 identities pass; state: complete.

Checked 1152 points, 972 derivative evaluations and 4608 polynomial identities.

Independent Rodrigues/force calculations check the physical reference; a shared polynomial preserves its nonlinear calibration/time error across epochs. All 27 physical and 15 auxiliary columns remain. This is not a native propagator, a long-record usefulness result or calibrated observational coverage. No native evaluations, archive reads or observed fits.
