and verification availability. The analytical specifications and proofs are contained in this source. No numerical execution, compiled archive, formal proof certificate, experimental calibration, or apparatus demonstration is supplied or asserted.

. Pauli randomization, measure-and-prepare channels, and general recovery/complementarity frameworks are established quantum-information constructions. The present manuscript claims the explicitly stated finite dynamical realization and its model-specific calculations, not novelty for those underlying principles.
