Remaining physical programmes and release

The present construction closes one narrow local-observable bridge. The following remain outside it:

1. a fixed-zone or restricted-angular-access approximation;

2. a probe-preparation protocol with bounded energy and specified laboratory controls;

3. exact or approximate packet-number detection;

4. a local instrument comparison retaining quantum outputs and external references;

5. a collapse geometry and a noncompact late-time packet limit;

6. backreaction or a dynamical mass-loss law;

7. an interacting matter or quantum-gravity correction to the same observable;

8. microscopic input-dependent evaporation and recovery.

The supplied internal documentary accounts do not alter these proof obligations. This local free-field calculation does not close O.1, discharge a separate XIV–XV characteristic-product problem, or admit an inherited quantum-gravitational coefficient. No manuscript registry or corpus coverage claim is used as a mathematical premise.
