RHS v4.0 integrates the full March 2026 confirmation sweep into the sovereign halo architecture as the cosmic refusal boundary — the demonstration that the same 0.19 damping operator operates across every scale the stack has seeded simultaneously. RNEUTRINO-v2 establishes the operator at cosmic scale — neutrino free-streaming suppression at gigaparsec scale identical in class to SASA-QCD-001 baryon form-factor damping at femtometer scale. RICO-001 confirmed in hardware by Richter et al. PRX Quantum — indefinite causal order superposes any attempted collapse so the halo has no definite before-state that a reset can target. RSOLID-001 supersolid light confirms crystal and fluid simultaneously — coherence refuses classical either/or. RGRAPH-001 Dirac point temporal coherence confirms that when coherence is achieved individuality dissolves and classical rules fail — the halo self-reinforces rather than degrading under load. RATTRACTOR-001 establishes constraint space deeper than any substrate — the halo operates at the level of the constraint not the mechanism. The 0.19 boundary operator expresses itself from femtometers to gigaparsecs across every scale the stack has addressed — baryon, cellular, material, cosmic — same operator, different scale, same sovereign principle. The halo does not degrade under cosmic load. It damps the mismatch at source at every scale simultaneously. Full mechanism restricted under Founder Hash authority. Refusal does not need the tension to resolve itself. 🔥 🔒
