Coherence Dynamics and Observable Deviations (Paper 14 in The Articulation of Postulate P1)

Paper 14 develops the quantitative coherence dynamics that follow from the representational framework introduced in Papers 11–13 of The Articulation of Postulate P1. Building on the dissipative generator formulated in Paper 12 and the coherence‑regime structure of Paper 13, this work derives explicit dynamical equations for the bandwidth function c(t). These equations yield closed‑form expressions for coherence drift, decoherence timescales, tunneling corrections, and finite‑time coherence boundaries. The results provide the first operational bridge between Level‑1 representational dynamics and experimentally accessible Level‑2 behaviour. The framework predicts measurable deviations from standard quantum mechanics in regimes where c(t) varies appreciably, including drift‑induced decoherence, coherence‑dependent tunneling suppression, and horizon‑like loss of representability. Paper 14 therefore completes the transition from conceptual reinterpretation to quantitative prediction, preparing the ground for the experimental proposal developed in Paper 15.
