Immediate and coherent implementations that agree

Before readout, the coherent pointer is quantum, not an already existing classical geometry. The proposition compares the completed outputs. It does not equate arbitrary intermediate geometric traces or authorize an intervening controller to inspect pointer coherences. This is consistent with the restricted deferred-readout boundary of VII-E and with precise circuit formulations of deferred measurement CheungVIIE, GurevichBlass2022 (Theorem thm:deferred).
