Laboratory Interface on Mesoporous Forsterite after the Locked Landauer Envelope

Abstract

A multi-level encoding on a crystalline grain is lost if the laboratory interface that addresses it is allowed to poll the encoding continuously. The parent record specifies Gao-type mesoporous forsterite Mg2SiO4 as the host class, matched S0 (carbon-coated) and S1 (carbon-removed) powders as the laboratory pair, falsifiers F1–F3, and a Landauer envelope: erasure of an unknown alternative costs at least kBT ln 2, entropy leaves through a sink, and bath statistics are not written back into the register Hamiltonian. This paper does not revise that envelope. It specifies the bus that a spectrometer, microwave line, or control pin set is allowed to present to that grain. The bus has three layers and one sink, all on the same powder. Layer-H is the coherent volume: localized multi-level centers in the carbon-removed lattice, inside the parent density window. Layer-M is a read-only reduction at the boundary of that volume: it extracts a binary cycle-complete flag and must not update Layer-H couplings. Layer-I is the classical pin set. Halt freezes Layer-I and leaves Layer-H running. Sink-P is the native acoustic spectrum of the as-grown ~2.58 nm pore walls. Hilbert-space dimension d is the dimension of the encoding. Day-1 continuous-wave X-band EPR on matched S0/S1 remains the experimental gate of the parent. No new spectra are reported.
