A Two-Boundary Coherence Framework: A Falsifiable, Cross-Domain Program and a Path Toward Unification

This manuscript proposes and details a falsifiable test of a minimal extension to the ΛCDM cosmological model, in which the path-integral measure is weighted by a small, covariant scalar density favouring coherent, information-rich structures. The principal test is a cross-correlation between the CMB (Planck 2018) and galaxy morphology from Euclid Q1 deep fields, feasible with existing public data and a high-end workstation. The document includes methodology, statistical power estimates, along with discussion of complementary laboratory experiments. This upload serves as a timestamp of conception; public release will follow completion of the initial CMB–Euclid analysis.
