Effective Geometry as Horizon Boundary Accounting: A Horizon-Ledger Bridge from Finite Distinguishability

Yining Wu · 2026-05-19

Structural Trident II. Interprets effective geometry as horizon boundary thermodynamics from finite distinguishability: horizon area functions as a boundary-entropy ledger; heat flux across the horizon updates the ledger; and requiring the ledger to close locally and covariantly recovers Jacobson-class effective geometric dynamics. Does not derive general relativity from FDS alone, replace Einstein gravity, or derive quantum gravity. Includes non-equilibrium ledger residuals, Phase-B geometry selection, covariant consistency conditions, and an explicit bridge to the X1 horizon-maintenance density scale.
