Declarations

and attribution. The exact correction criterion, Stinespring continuity, entanglement-breaking structure, and thermal equality have established sources identified in the bibliography. Cheung's manuscripts are cited by identifier and version where appropriate. The present contribution is a standalone finite proof package and an explicit correction of the proposed classical-record narrative. No claim is made that the standard channel results are new.

provenance. Internal manuscript comparisons use the supplied excerpts and the Enter Calculus Companion records. Full independent verification of the entire registered corpus is not asserted. The journal record for Cheung's Enter article is distinguished from the undated internal manuscripts; its publication metadata are not transferred to them.

scope. No gravitational Hamiltonian, backreaction law, microscopic evaporation endpoint, island, quantum extremal surface, or gravity-generated-entanglement test is constructed. The conserving register Hamiltonian $H_0$ is not a gravitational mass law. Information-free residuals are not identified with physically nonexistent remnants.

and build. This file contains its own bibliography and requires no external figures or generated data. It is written for pdflatex. No successful compiler execution, proof-assistant verification, independent symbolic execution, laboratory calibration, referee approval, or journal acceptance of Hawk05-A is asserted.
