Destructive readout is a complete instrument

This is the finite-instrument discipline of En10-A and En09-A CheungEn10A,CheungEn09A. Conditional reference steering is compatible with an unchanged unconditional reference marginal. The identity does not remove externally scheduled preparation and measurement time.

Channel tests consume their probe registers. They are separate runs, not a nondestructive readout of the unknown payload being transported.
