The distinction between sources and proof inputs

The supplied Cheung texts are identified by manuscript names, versions, and labels where available. Their models are not identified with one another or with $A_V$. The public companion describes itself as a searchable companion, not a proof checker CheungPortal.

Family 280 is attributed to OpenAI by the supplied .pdf. The catalogue association and Lean scope metadata come from the supplied dossier OpenAI280,Dossier. No independent manuscript-registry audit is claimed.

Theorem thm:main uses only its printed finite statistical and channel assumptions. The separation theorems use locally proved examples and the explicit quantifiers of Definition def:determination. No Family 280 theorem is a premise of either argument.
