Evaluates evidence for dark matter alternatives using SLACS lensing and CMB validation, suggesting new insights.
This R136 Master-Lock release consolidates the Karahan-Einstein Framework / MEON V50 evidence chain from R125 through R133_FIXED. It packages the prior R125-R131 release together with the R132 full Planck Cobaya minimize outputs and the R133_FIXED BAO/LSS validation outputs. R125 reports a direct SLACS strong-lensing equation audit on real lenses, with MEON test chi2 28.274977 against SIS chi2 57.486079 and held-out median Einstein-radius error 0.135965. R130 reports a strict local Planck 2018 TT binned audit with MEON/LCDM reduced-chi2 ratio 1.0077697043350071. R131 reports an official Planck Plik-lite TTTEEE clik/clipy evaluation with MEON delta(-2 logL) versus LCDM 0.3765714082040858. R132 extends the CMB validation to a full Planck Cobaya minimize using full Plik TTTEEE, low-l TT, low-l EE, Planck lensing, CAMB, and nuisance parameters. In the local minimize run, LCDM chi2 is 2765.271, MEON chi2 is 2765.8868, and the MEON-LCDM delta chi2 is 0.6158000000000357. Baryon-only gives chi2 240162.2, showing the need for a cold clustering sector or equivalent. R133_FIXED resolves the earlier BAO/LSS setup issue by installing and testing explicit Cobaya BAO/RSD likelihoods. It records 29/29 successful likelihood install attempts, 5/5 usable likelihood sets, and 14/15 completed model runs in minimize mode. The usable sets include DESI 2024 all, DESI 2024 split, DESI DR2 all, SDSS legacy BAO, and SDSS/eBOSS BAO-RSD. MEON remains effectively degenerate with LCDM across the parsed BAO/LSS best-fit chi2 comparisons, while baryon-only is strongly disfavored where it completes. Scientific caution: R136 is a master evidence lock, not a final claim that all dark-matter evidence has been replaced. R132 and R133_FIXED are minimize/best-fit checks, not full posterior MCMC chains. R134 cluster lensing remains DATA_REQUIRED because no usable radius-resolved cluster-lensing profile table was found. Full MCMC, cluster lensing, full-shape large-scale structure, and independent third-party reproduction remain required before a complete cosmological replacement claim can be made.
