Row 1: the collapse analogy

Thus a mathematically correct version of the first row is:

After an independently supplied finite preparation, a complete isometry preserves the code globally. A chosen relocation isometry can place its full recovery interface in the residual.

The code is what is encoded. Fixed source and apparatus ancillas are not additional unknown logical inputs unless the declared code has been enlarged to include them.

No event horizon, singularity, area theorem, or surface of no return is derived from the Enter readout convention or from Theorem thm:global. No energy-to-geometry implication is asserted.
