Quantum theory is precise, but coherence is fragile: phase relationships decay, information leaks, and every platform fights the same enemy - decoherence. This article extends the Chronon Field program by reframing that fragility with a clean operational split: Phi(x) as a local tempo parameter (cadence), and Gamma(x) as a loss channel (decoherence). The point is not to add a new force, not to touch the metric, and not to rely on metaphysical language. The point is to define an interface that can be tested. The core idea is simple: information “breathes” in time. Coherence persists when tempo and loss remain compatible; it collapses when local tempo gradients or coupling asymmetries push Gamma upward. This paper translates that intuition into the language of open quantum systems (T2, Tphi, Lindblad-style loss) and highlights what would count as admissible evidence: differential / invariant observables, explicit null tests, and veto logic against environmental drift. Positioned as a continuity piece between the treatise Time Is Not What We Think! and the CHRONON-1 operational roadmap, Quantum Rhythm provides the conceptual bridge from “tempo as substrate” to measurable coherence signatures across quantum platforms - without smuggling claims that the data cannot support.
