VII-J-ST@1#eq:programme

This is the I-B/En09-A finite interface CheungIB,CheungEn09; its conditional block is not a metric, stress tensor, or singular detector.

For fixed continuation channels $F_{a}$ , the full programme channel is

J (X) = a \sum ∣ a ⟩ ⟨ a ∣_{R} \otimes F_{a} (D_{a} X D_{a}^{†}) .

It is CPTP because each continuation preserves the trace of its unnormalized block. Routing choices and record delivery must be implemented before the receiver uses $a$ . An arbitrary state-functional selection of $F_{a}$ is not this channel.
