This evidence package documents the MEON R39–R50 diagnostic sequence, extending the earlier HFF Kappa and Bullet/CMB analyses into a structured simulation-stress and reconstruction-challenge framework. The package summarizes a series of preregistered computational audits applied to public Hubble Frontier Fields Kappa reconstructions, Chandra/X-ray and optical proxy layers, WebSky external ΛCDM convergence simulations, and cluster-matched ΛCDM-like reconstruction mocks. The sequence begins with simulation stress testing and non-standard cluster identification, then advances through targeted multi-layer follow-ups of Abell2744 and Abell370, WCS-matched Chandra/HFF recovery diagnostics, low-Kappa/void lacunarity texture analysis, conservative matched-null validation, posterior-predictive ΛCDM proxy tests, external WebSky comparison, and finally a cluster-matched ΛCDM reconstruction challenge. Across R48–R50, the audits identify repeated mismatch or stress signatures in HFF Kappa maps relative to increasingly constrained ΛCDM-like comparison envelopes. The strongest result in this package is R50, where 25 public HFF Kappa maps are compared against cluster-matched ΛCDM-like reconstruction mocks designed to preserve peak geometry, halo morphology, smoothing, projected large-scale-structure texture, and reconstruction noise. R50 classifies 11 maps as strong cluster-matched ΛCDM mismatch candidates, 7 as mismatch candidates, 5 as stress candidates, and 2 as compatible or inconclusive. This does not constitute a final falsification of ΛCDM, because the comparison mocks are parametric rather than full hydrodynamical ray-tracing simulation ensembles. However, the result establishes a strong reconstruction-level mismatch signature and motivates a final follow-up using published cluster-matched ΛCDM simulation products and HFF-like mock lensing reconstructions. This release is intended as an evidence and reproducibility package for further review. It should be interpreted as a diagnostic research framework, not as a definitive cosmological claim. The central contribution is a reproducible audit pipeline for testing whether observed HFF Kappa scale structure, low-density texture, and multi-layer offsets can be reproduced by progressively stronger null, simulation, and reconstruction controls.
