Quantum Structural Theory of Harmony (QSTH 6.3) – Ledger Reality Reconstruction: I‑Dim Mediation, DM/DE, and Arrow-of-Time Diagnostics (with the Eddington Paradox)

Quantum Structural Theory of Harmony (QSTH) 6.3 — Ledger Reality Reconstruction: I-Dim Mediation, DM/DE Mapping, and Arrow-of-Time Diagnostics (with the Eddington Paradox) QSTH 6.3 advances the QSTH 6.x “operational” program by presenting a compact, falsifiable framework for reconstructing how observed 4D physics may be mediated by a deeper bookkeeping layer (“ledger”) that tracks the residual balance between coherence-organized change and irreversible reduction. The central object is the ledger balanceS_eff ≡ ΔS_coh − ΔS_red,treated as a regime-dependent closure input mapped into effective observables via an interface transparency diagnostic (α_interface) and an explicit closure functional. The goal is not to add a new ad-hoc ingredient, but to deliver an audit-ready, cross-channel pathway:signatures → datasets → null tests → publishable constraints,where null outcomes remain valuable and tighten the admissible regime windows. This Zenodo record contains three parts: Main CORE Paper — the conceptual kernel and falsification map. It defines minimal claims, operational reading of the ledger variables, and a set of observational “handles” (cross-probe consistency checks) intended to constrain ledger bias, I-Dim mediation, and arrow-of-time diagnostics across cosmological channels. Appendix Pack — implementable technical notes, operational proxies, and systematics discipline. It includes a compact notation & cross-link map, candidate I-Dim proxy constructions (simulation-based and data-based), a “systematics kill-list”, and a one-page reporting template for reproducible constraint attempts. Publication 15 (OSF): “The S_eff–Eddington Paradox” is included/cited as a companion capstone linking S_eff to luminous channels (stellar / black-hole accretion) via an entropic-ledger reinterpretation of the Eddington limit, providing an astrophysical closure-style constraint complementary to the QSTH 6.x program. Related works and archive note (continuity across the series): QSTH 6.0–6.2 (CORE releases) are available on Zenodo under the QSTH series. QSTH 0–QSTH 4.0 (foundational series) are archived and published on OSF. Publication 15 (OSF): “The S_eff–Eddington Paradox” is included/cited as a companion capstone linking S_eff to luminous channels (stellar / black-hole accretion) via an entropic-ledger reinterpretation of the Eddington limit, providing an astrophysical closure-style constraint complementary to the QSTH 6.x program. What this release offers readers (practical value): A minimal, test-first formalism for ΔS_coh, ΔS_red, S_eff and their observational projection (α_interface, closure functional). A falsification-oriented workflow where null results remain publishable constraints (cross-dataset consistency discipline). A ready-to-use appendix toolkit: symbol legend, cross-links to earlier QSTH releases, I-Dim proxies, null tests, and reporting templates.
