Evidence and source policy

Cheung references identify the supplied manuscript codes and versions. Their use here is documentary and comparative. No proof depends on an unprovided theorem from those manuscripts.

External mathematical inputs are stated explicitly. Model-specific constructions and estimates are proved below. No exhaustive novelty claim is made.

The supplied OpenAI catalogue contains proposed mathematical ingredients, not verified premises of this paper SuppliedCatalogue. Its spectral-gap, area-law, geometric, and entropy claims are not used to establish SYK recovery or gravitational evaporation.
