Can Quantum Effects and Relativistic Redshift Emerge from One Frozen Geometric Scaffold? A Structural Audit in the Methane Metauniverse Framework

This article presents a structural audit of the Methane Metauniverse framework. The central question is whether one frozen geometric response scaffold, defined by fixed K, M, and C matrices, can reproduce formal response patterns associated with quantum effects and relativistic redshift without retuning the matrices for each sector. The audit tests projection based observables, 21 cm hyperfine transfer, Stark response, Zeeman response, Larmor response, Rydberg and Schrodinger scaling, Dirac like two state algebra, general relativistic redshift form, and a first Yb ion E2 E3 clock diagnostic. The result is a structural pass. The frozen package remains stable and produces the expected formal signatures across the tested modules. This work does not claim empirical proof of the MMU framework. It provides a reproducible computational protocol and a basis for future falsification tests against independent precision data.
