QICT at Maximum Referee Standard: Formal Dependency Graph, Certified Predicates, and Proof-Only Claims (with Explicit Model Boundaries)

We present a maximal referee-grade formulation of the Quantum Information Copy Time (QICT) program. All claims are restricted to (i) standard Axioms (locality, stationarity/KMS, conservation), (ii) executable certification predicates, or (iii) Theorems with fully enumerated premises. The key observable is the copy time \( \tau_{\text{copy}} \), defined operationally via Helstrom distinguishability. A certified hydrodynamic-window predicate CHW (constructed from finite-time witnesses and residual tests) gates every micro--macro statement. Under \( \)CHW we derive diffusion and prove the central scaling \( \tau_{\text{copy}} = \Theta\!\left(\sqrt{\chi^{(2)}_{\text{micro}}}\right) \), where \( \chi^{(2)}_{\text{micro}}=\langle \delta Q,\,(-\mathcal{L}_\perp)^{-2}\,\delta Q\rangle_{\mathrm{KM}} \) is a second-moment fast-complement susceptibility. Optional bridges (thermal modular saturation and Higgs-portal matching) are isolated as explicit model Axioms; the "Golden Relation'' is then a Theorem and is non-circular provided an independent \( \tau_{\text{copy}} \) inference NC is satisfied. We include an explicit, dataset-level certification appendix (tables generated from bundled validation outputs), enabling direct audit.
