ACDM flavored fried chicken version of Galaxy Dnynamics
RESEARCH EXPERIMENT: the author does not believe the LCDM recipes, halos or particle readings here. It maps how a LCDM group could reverse-engineer the law, so the route is on record first; nothing here is a framework result. Working note, version 1.5 (2026-11-03). AI-assisted; not peer reviewed; not reproduced by any outside group. kappa = 1/2 is fitted; the theory is not closed; nothing here says the data favour this law over LCDM. Fried chicken is a nickname and carries no physics. An analytic stand-in for feedback, not a hydrodynamic simulation. New in 1.5: the title spelling is corrected (Dynamics), and Amendment A13 asks whether any scale already in LCDM supplies the dark energy tie with no hand term. None does. Milgrom's coincidence c^2 sqrt(Lambda/3)/2 pi matches the number (kappa_eff 0.461, flat in z) but Lambda's pull at 10 kpc is 1.1e-5 a0, so it acts on nothing in a galaxy; cH/2 pi rises 3.4 times by z 2.33; the NFW central acceleration is 0.83 a0 at 1e12 solar masses but spans about 0.5 dex either way over mass and scales wrongly with cosmology; the Tully-Fisher scale at the cosmic baryon fraction is 0.20 a0. How easily can LCDM's knobs reproduce the law g_N = g^2/(g + a0), on the measured baryons of 171 SPARC galaxies? Twelve supernova-feedback knobs, as one global recipe, land the fitted scale within 0.3 % of a0 and 0.0415 dex from the law (0.0445 on held-out galaxies), and score 0.1953 dex against observed curves, the law scoring 0.1951. Fourteen knobs reach 0.0275 dex. Six knobs per galaxy within 2 sigma priors pass the frozen 0.02 dex target at 0.0152 dex, with at least half the galaxies at the low concentration bound. The tie to dark energy did not come from the knobs: five hand-written terms at extreme values, and kappa still narrowly missed. Tuned to the law, so a match shows freedom, not explanation. All knobs disclosed; recipes added after first numbers are marked. New in 1.1: R12, a CDM halo defined from the formula with a = kappa c sqrt(G rho_DE), kappa = 1/2 by hand. It passes every target exactly by construction, which is not evidence, and the tie needs a coupling to dark energy that LCDM does not contain. Also new, a grade on KiDS-1000 lensing, 60 points, nothing refitted, gate p >= 0.01. All rows fail: law 276.1, twelve knobs 277.9, fourteen knobs 242.1, R12 stopped at R200 with a two-halo term 457.7, untuned LCDM control 563.1. New in 1.2: R13, one global recipe with 21 knobs and 5 hand terms, tuned jointly to the law on SPARC, to KiDS and to X-COP, against a frozen scoreboard. Verdict: not complete, failing the exact law target, KiDS (145.2 on 60 points), holdout and plausibility. R14 passes KiDS only with per-bin freedom, and every line passes only as a patchwork of about 1066 parameters, not one theory. On X-COP and KiDS the tuned recipe fits the data better than the plain law (mean -0.467 dex and 276.1). Also an effective particle reading, which the author does not hold as physics: no single equation of state holds these halos, and a real particle halo passes Cassini and predicts Newtonian wide binaries. New in 1.3: a one-scale action tying the field's cap to rho_DE, reproducing the law to 0.00004 dex. It is a posit, not a derivation; kappa stays fitted and it has no cosmology yet. Prior art is cited: the field equation is Zhao and Famaey 2006, and a limited search found close neighbours but no exact match. New in 1.4: this notice, and a correction: the capped function in the one-scale action comes from the author's own earlier AeST embedding, PAPER59 (doi:10.5281/zenodo.23585319), which v1.3 failed to cite. New in 1.5: the title spelling is corrected (Dynamics), and Amendment A13 asks whether any scale already in LCDM supplies the dark energy tie with no hand term. None does. Milgrom's coincidence c^2 sqrt(Lambda/3)/2 pi matches the number (kappa_eff 0.461, flat in z) but Lambda's pull at 10 kpc is 1.1e-5 a0, so it acts on nothing in a galaxy; cH/2 pi rises 3.4 times by z 2.33; the NFW central acceleration is 0.83 a0 at 1e12 solar masses but spans about 0.5 dex either way over mass and scales wrongly with cosmology; the Tully-Fisher scale at the cosmic baryon fraction is 0.20 a0.
