What probably matters to youSection of the release
Refusal-fallback metadata including fallback model, lane, credit code and original-model stamps is plumbed into requests, with no user-facing control.
What
Requests now carry a block of fields describing a fallback used after a model refusal, including the fallback model, its lane, a credit code and mint details, and stamp fields recording the original model, category, trigger and request id. Plumbing for that path; nothing here is user-settable.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
