Entanglement as Compensation in a Two-Layer Universe — Structural Time, Observational Time, and the Boundary-Exposed Limit (ER Bridge)

Supplementary calculator for this record (DOI: 10.5281/zenodo.18186403) This record is accompanied by an open, reproducible "True Edge of the Universe / Boundary vs Observable (CMB) Comparator" calculator. What the calculator does We model an interference or interaction residual as an exponential profile: I(R) = I0 * exp(-R/L) An effective "end" radius R_end is defined by the termination criterion: I(R_end) / I0 = 10^(-k) which yields the closed-form expression: R_end = L * k * ln(10) The calculator compares this value against a chosen reference radius R_ref (for example, the observable radius R_obs) and reports: Delta = R_end - R
