Make versor construction fail closed instead of synthesizing hash-derived fallback rotors. - remove pseudo-random construction fallback from unitize_versor - add signed residual helper for +1 field states vs ±1 manifold entries - validate vocab manifold entries with full residuals - document antipodal transition rotor failure contract - add focused invariant tests for versor closure and manifold validation
