This paper presents a Coherence Geometry interpretation of Planck’s constant as a natural action scale arising from phase closure in structured coherence fields. Planck’s constant is traditionally introduced as an empirical constant. In this paper, a natural coherence action scale \ (S₀\) arises from the requirement that stable \ (\) -field structures close phase cycles in integral multiples of \ (2\). This quantizes action increments as \ (S = 2 n S₀\). The standard quantum relations follow once \ (S₀\) is calibrated to laboratory data, yielding \ (S₀ = \). The result is structural rather than numerological: the paper does not claim to derive the measured numerical value of \ (h\) without calibration. Instead, it argues that an action scale of the Planck type appears naturally from phase-constrained coherence geometry, with numerical value fixed by physical units and experimental comparison.
