The Sign Premise Is a State Clause: Pumped Baths, the de Sitter Thermostat, and the Limits of Scale Without Law

Short summary

This paper argues that the anti-MOND sign theorem's premise is the bath's state, not ghost-freedom, and that a population-inverted steady state can flip the sign of the worldline mass shift. However, it establishes a 'rigidity wall,' showing that free fields or the de Sitter horizon cannot achieve this sign flip, requiring an anharmonic medium.
