Per-Galaxy a0 Variation: Angular Velocity-Field Complexity as Carrier of Hidden State (v16 — Programs 1-12, Dark Matter Discrimination)

v16 — Dark matter model discrimination (Program 12: DM-1 through DM-4V). Single archive (3.2 MB, 648 files): analysis scripts, result JSONs, source code, data files, documentation. Core Result (unchanged): Hidden state H drives bilateral Vf_Resid-a0_Resid coupling at r = 0.77 (LOO, p < 0.001, N = 55), replicated on N = 59 independent galaxies. 1D information ceiling: 88.5% inaccessible. Red team: 11/11 pass. Program 12 — Dark Matter Discrimination Series: DM-1 Kill Constraints: 12 mandatory constraints tested against 7 DM models. CDM smooth DEAD (6 fails), MOND DEAD (10 fails). CDM+halo shape: 12/12 pass. DM-2V Verification: CDM+shape vs SIDM — SIDM signal was coverage artifact. r(DQ, outer C) = 0.746 vs r(DQ, inner C) = 0.431. LOO inner-led: 0/7. CDM+shape CONFIRMED. DM-3 Fuzzy DM: Wave fingerprint test — 0/4 for Fuzzy DM. No wave signature. Fuzzy DM DEAD. DM-4 + DM-4V: shapeAmplitude captures H at r = 0.80, p = 0.028, LOO 7/7 positive, bootstrap 97.8% positive, bar-exclusion stable. CONFIRMED. Model Status: DEAD: CDM smooth, MOND, Fuzzy DM. No signal: SIDM, WDM. LEADING: CDM + non-axisymmetric halo shape (shapeAmplitude r=0.80). Data: SPARC (Lelli, McGaugh & Schombert 2016); THINGS (Walter et al. 2008).
