A closed system, composed of repeating lattice geometries, rested at final entropy. The distinction between system and environment collapsed into redundancy. Every possible interaction had already resolved to completion. Energy, as a concept, had flattened. No transfer, no transformation, no storage. All thermodynamic potentials stood equal, and so none applied. Structural persistence was neither active nor passive—it was the direct result of all variables having achieved minima in parallel. There were no echoes. Nothing remained to be recorded or interpreted.
