The Penn / Geometron Framework v2.5 is a public conceptual release of a speculative geometry-emergence architecture. It explores whether particles, fields, mass, gravity, chemistry, and strong-field compression regimes can emerge from cooperative networks of local geometry-building units called Geometrons. This version integrates network coarse-graining, catch anatomy, flux shredding, expression-layer self-knotting, baseline span consumption, dual compression, stadium-wave propagation, and a guarded strong-field core-merger branch. The framework is not established physics and does not claim to derive general relativity, quantum mechanics, the Standard Model, or quantum gravity. It is released as a conceptual architecture for criticism, formalization, testing, and possible falsification.
