Enter is an output interface

The operational philosophy of Enter distinguishes a consumed quantum name from a returned quantum system. Destructive readout returns a classical record and whatever other quantum factors the interface explicitly retains. Consumption is a statement about access and output type, not physical annihilation of every implementing degree of freedom. Quantum recovery is a different task: its output must return the specified quantum information, including the required reference correlations. Equality of channels also does not specify a thermal machine or a heat ledger.

These distinctions are central to Cheung's account of Enter CheungEnter,CheungPhil,CheungI. We use specified Born semantics and prove the channel identities needed here. We do not import a measurement-uniqueness theorem from a shortened list of its hypotheses. The spacetime interface follows the prescribed-background interpretation of I-B CheungIB, not a reconstruction of geometry from records.

The phrase

will have only the following typed meaning: a designated finite clock encoding is consumed, whereas the three named spatial-carrier factors survive. It does not mean that the coordinate $T$, the manifold, or a geometric dimension is destroyed.
