Directive Driven Phase Step Collapse and the "Ratio ≈ 1" Universal Law

**Unification Across Scales**This section and Table 1 have been expanded to illustrate how the “Ratio ≈ 1” criterion unifies phenomena across all scales—from quantum‐optical tests and atomic/mesoscopic experiments, through particle‐physics thresholds and condensed‐matter transitions, to cosmological epochs and gravitational timing.
