Origin Field Theory: Finite-Ensemble Stability-Prior Demonstration

Version 1.6.4 is a physical-extension and diagnostic update to the Origin Field Theory stability-prior package. The original v1.3 draft proposed a broad atemporal law-selection framework involving an Origin Field, a Focus Operator, observer capacity, and stability-based universe selection. The v1.5.x releases narrowed that proposal into a reproducible methodological test: constructing and auditing stability-weighted priors over a declared finite elementary-cellular-automaton ensemble. Version 1.6.4 keeps that ECA pipeline intact and adds a separate physical-extension layer. This extension defines a finite bounded candidate space over two physically motivated parameters, the cosmological constant ratio Λ/Λobs and gravitational constant ratio G/Gobs, then maps those candidates to an observable CMB shift-parameter approximation. It computes likelihoods using public Planck-derived distance-prior values and compares the stability prior against uniform, Jeffreys-proxy, and constrained maximum-entropy log-space baselines. This release also adds resolution diagnostics through 200×168 grids, prior-only heatmaps, prior-likelihood overlap analysis, Bayes-factor sensitivity checks, reproducible result tables, figures, tests, PDF documentation, release validation, manifest files, and SHA-256 checksums. The supported claim remains limited. This package demonstrates a reproducible method for defining, applying, and auditing stability-weighted priors over finite candidate ensembles, including a first physical observable bridge. It does not establish a confirmed physical law-selection mechanism, consciousness-driven cosmology, or modification of standard physics. The physical extension should be interpreted as a diagnostic and methodological bridge, not a full cosmological analysis.
