Enter and its interpretation

The Enter background distinguishes destructive readout from quantum return. A measured quantum name is consumed; the declared output is a classical record together with the explicitly retained residual. Recovery from an accessible subsystem is a different task EnterI,EnterPhilosophy.

We use this discipline only after constructing the field-theoretic objects. In particular:

1. an encoded number is not the continuum field from which that number was mathematically evaluated;

2. a channel identity is not a thermodynamic implementation or a field detector;

3. a finite dependency schedule is not a derivation of a light cone;

4. a prescribed spacetime supporting finite operations is not spacetime emerging from those operations.

The spacetime Enter model of I-B supplies the relevant fixed-host interpretation IB. The finite instruments needed here are proved directly below.
