This manuscript proposes a four-channel audit framework for systems in which phase, coherent amplitude, retained history, and leakage jointly shape observable structure. The framework distinguishes retained history, represented by Γ, from exported or erased history, represented by leakage channels such as contrast loss, heat, radiation, degradation, or forgetting. Rather than replacing established theories in physics, thermodynamics, chemistry, or biology, the paper offers an operational bookkeeping language for asking when information compressed into noise, damping, probability, or phenomenological loss may instead be separated into phase, amplitude, retained history, and leakage. The result is a conservative audit map for evaluating whether a proposed retained-history coordinate is causal, predictive, robust across channels, and responsive to controlled history or leakage perturbations.
