Existing algebraic holography is not denied

There are rigorous algebraic holography constructions, such as Rehren's correspondence between nets on a supplied anti-de Sitter spacetime and nets on its conformal boundary Rehren. They require their spacetime, covariance, region correspondence, and observable identifications. They are not obtained from Record record:extensions simply by replacing “extension” with “bulk”.

This companion neither applies such a construction nor claims that no holographic relation can ever be added. Its refusal concerns an unsupported gravitational identification in the present package.

The fixed Schwarzschild exterior of Em03-A and the declared Einstein–scalar background of Em02-E are different supplied source models CheungEm03A,CheungEm02E. Neither is identified with $A_V$, $B$, or a Q-system here.
