Randomized trial evaluates modified Jeans equation outcomes in dwarf spheroidals, suggesting significant improvements over existing estimates.
Solves the spherical isotropic Jeans equation for 22 MW dwarf spheroidals using the RAR-validated interpolation function ν(x) = 1/(1−exp(−√x)) from CDN-265. Plummer stellar profile with Abel projection to luminosity-weighted σ_los. Results: Jeans recovers 3/22 within 20% (Fornax 1.06, Leo I 0.99, Leo II 0.82) versus Wolf estimator 0/22. The Jeans integral improves every prediction by 10–15× over Wolf by accumulating ν-enhanced gravity over the full radial profile (effective boosts 6–139× in σ²). MOND simple and RAR ν produce identical σ_Jeans, confirming GCFT = MOND at dSph scale. Remaining gap is luminosity-correlated (1.3× for massive classicals to 57× for faint ultrafaints). The CDN-265 "two-sector" finding is reframed: substantially an estimator artefact, with the residual deficit matching the known MOND dSph problem (external field effect, tidal stripping, anisotropy). Pre-registers CDN-267 for MW external field effect and velocity anisotropy.
