A Condensed-Matter-Style K/M/C Weak-Field Audit of GR-Like Redshift and Clock Response in MMU v6.3

OSF-ready article documenting the MMU v6.3 v5.1 frozen K/M/C weak-field redshift and clock structural audit. The audit tests whether the volumetric w4 sector supports a GR-like weak-field clock response under the frozen non-canonical K/M/C package, using the MMU scaling K(q)=K0(1+q)^(-3). The run passes the structural proxy test with omega(q)/omega(0)=(1+q)^(-3/2) and first-order response delta omega/omega approximately -3/2 q. The result supports weak-field redshift compatibility at the structural level only. It does not derive the Einstein field equations, a physical metric, the Schwarzschild solution, G, or the exact bridge between q and Phi/c^2.
