The Physics of Coherence Vol. II

Physics of Coherence, Volume II This paper is the second volume in the Physics of Coherence series published by the Upstream Coherence Measurement Stratum (UCMS). Volume I (The Physics of National Survival: Structural Coherence, Seam Shear, and the Sovereign Intervention Window) established the foundational framework: the Static Fallacy, Seam Shear, Geometric Thinning, and the Intervention Window doctrine across five cross-domain case studies.Volume II develops the apex validation case. The Fukushima Daiichi event (11 March 2011) is reconstructed as a seam failure sequence using three categories of physics-determined constraints — thermal-hydraulic decay envelopes, universal temporal anchors, and shared infrastructure coupling logic — that limit the range of plausible event timelines independently of operator testimony. Four structural seams are characterized, including a nine-year regulatory-operator Intervention Window (2002–2011) with a coupling coefficient of approximately zero throughout. A novel R_c proxy calculation applies autocorrelation to the risk divergence signal D(t), yielding R_c = 0.363, confirming the signal as structurally persistent. Three domain-agnostic observable signal classes — risk model divergence, regulatory review delays, and infrastructure redundancy gaps — are derived as a measurement specification for real-time seam intelligence deployment.
