Presents ten independently falsifiable hypotheses characterizing a structured pre-failure regime in human systems, grounded in the Standard Coherence Fidelity Layer (SCFL) and Upstream Coherence Measurement Stratum (UCMS). Each hypothesis is operationalized using established SCFL operators (ΔG(t), φ(t)), seam physics primitives, the 24-event Rupture Atlas, and GYOR operator-theoretic regime encoding. The formal dynamical base draws on P76 (universal rupture condition and forward invariance of the rupture set) and P77 (SCFL as a dynamical measurement system for human-centered systems). An empirical pathway is provided for Mode B validation using existing SCFL infrastructure. Four original schematic figures illustrate the saddle-node bifurcation in coherence state space (H4), normalized drift collapse across institutional domains (H10), entropy spike threshold alignment with coherence curvature (H9), and the Seam-X operator-defined transition manifold (Section 5). Appendix A positions the work relative to prior literature in complex systems theory, network theory, resilience engineering, information theory, and regime shift science.
