Quantum Structural Theory of Harmony (QSTH M. 4) — κR (Γ): Topological-State Seal of Horizon Closure

This publication continues the QSTH M. x Horizon Ledger Series by introducing κR (Γ) as a candidate topological-state closure label for audited horizon configurations. Rather than treating κ as a freely adjustable residual, M. 4 proposes that it may only be interpreted after an independent horizon configuration ΓR has been established and successfully passed the methodological audit called Horizon Sudoku. The work develops the distinction between: horizon regime (R-signature), horizon configuration (ΓR), ledger balance (BR), effective horizon entropy (SₑffH), and the candidate closure seal κR (Γ). The publication introduces the concepts of: Horizon Configuration ΓR, Horizon Closure Condition CH (Γ), Horizon Sudoku, Planck Lamp, Sackur–Tetrode Lamp, candidate statistical scaffold εR, regime-readable closure. Throughout the paper, methodological guardrails are emphasized. The de Sitter value κ_Λ = 1 is treated solely as a calibration reference and not as a universal physical law. The publication does not claim the discovery of a new physical constant. Instead, it proposes a structured audit framework specifying when a closure label may become physically meaningful. Within the architecture of the M. x series, M. 4 represents the transition from symbolic algebraic expressions toward auditable structural readout.
