10 COS-EXP - Collapsing-Structure Empirical Module: Observational Channels, Empirical Consistency, and Experimental Priorities

COS–EXP is the empirical interpretation and coordination module of the Collapsing-Structure (COS) program. It investigates how claims and candidate consequences from the discrete geometric, dynamical, and matter-sector modules — including COS-S, COS-QF/QSF/QD, COS-SM/SUSY/GUT, COS-C, and COS-NUM — can be organized into observational channels, empirical test targets, detectability categories, and reproducible pipeline requirements. The manuscript introduces a classification of COS-related claims across geometric, matter, topological, and dynamical scales, together with A/B/C detectability categories, an empirical-readiness scale, and degeneracy/identifiability blocks. It also treats the GR limit as a necessary empirical consistency link, clarifying how classical tests, cosmological background behavior, and possible deviations from GR should be interpreted within the COS framework. The paper surveys the main observational channels: GR consistency tests, CMB observables, anomaly and spectral-dip analyses, mutual-information-based CMB scale-asymmetry diagnostics, stochastic gravitational-wave background searches, neutrino-sector constraints, and large-scale-structure / weak-lensing probes. For each channel, it identifies associated COS parameter groups, observables, systematic risks, current constraints, and COS-NUM pipeline requirements. COS–EXP provides an empirical roadmap for connecting CMB, gravitational-wave, neutrino, and LSS surveys to different classes of COS-related test targets. Its purpose is not to present a complete set of numerical forecasts or independent experimental confirmations, but to establish a transparent empirical structure for reproducible COS-NUM analyses and future observational tests.
