Spatial Coherence C_{ij} as a Substrate-Agnostic Information-Theoretic Primitive Volume II: Cross-Domain Validation of Collapse Signatures

Volume I of this series defined spatial coherence C_{ij} as a candidate substrate-agnostic information-theoretic primitive for complex networked dynamical systems under stress. It supplied the formal definition, justified the hybrid L1/L2 normalization, established analytic bridg...

Coherence Physics Research Program: A Living Map of SCFL/UCMS Operators, Evidence Status, and Open Replication Gaps

A living scientific program map for the Standard Coherence Fidelity Layer (SCFL) and the Upstream Coherence Measurement Stratum (UCMS) research canon. This document distinguishes explicitly between established parent literatures (critical transitions, cascading failure, resilienc...

Spatial Coherence C_ij as a Substrate-Agnostic Information-Theoretic Primitive — Volume I: Formal Definition, Invariance Claims, and Placement within the Standard Coherence Fidelity Layer (SCFL)

This working paper introduces spatial coherence C_ij as a candidate substrate-agnostic, information-theoretic primitive for complex networked dynamical systems under stress, and formally situates it within the Standard Coherence Fidelity Layer (SCFL). While spatial coherence is c...

Seven Trajectories, One Curve: Cross-Grid Evidence for a Graded Coherence Response

This record reports a graded, cross-grid dose-response relationship in a coherence-based stress measurement across seven independent power-grid events on two U.S. transmission systems (ERCOT, PJM). Using a single, fixed coherence formula — C_ij(τ) = 1 − |x_i(τ) − x_j(τ)| / σ_ij —...
