Atomic-Scale Polaritons Under A Fixed Corridor: Tokens-Only Replay, Disable-L Nulls, And 4S3 Closure

This manuscript builds on the article "Hidden Magnetism Made Operational: CD-RPED and RIXS Under a Fixed Sign Contract" contract-and-triad philosophy and extends it to atomic-scale polariton control, treating near-field “control” claims as replication-fragile unless they are frozen into a declared invariant, fixed bands, tokens-only ridge rows (hashes + schemas), and preregistered falsifiers (flip-only, disable-L, boundary swap, withhold-node) under 4S3 leave-one-out auditing; the key move is that the same corridor discipline that prevents sensor-first persuasion in magnets is used to prevent pump/boundary artifacts from impersonating polaritonic directionality or refraction/focusing control, yielding a standards-ready audit overlay rather than another narrative review.
