Per-Galaxy a0 Variation: Carrier Identification via 2D Velocity Fields (v14 — Programs 1-10, MNRAS submission)

v14 changelog (from v13): Fixed inclination bug: inc values corrected from 0 to actual SPARC values Added seeded PRNG to permutation tests — p-values now deterministic (p=0.0053) Added MNRAS paper: complete LaTeX source + compiled PDF Added Program 10: Survey Census and Expansion Path Added THINGS FITS velocity-field data (18 files) Clarified partial correlations across pipelines Red team: 8/8 critical, 11/11 total tests PASS Governing result: r(DQ,m2)=0.847, p=0.005, N=7 THINGS galaxies.
