What

The switchModelsOnFlag setting, which automatically switches models when a response is flagged as a refusal, now reports its own telemetry event when you change it. It only appears when a gating check passes.

Details
  • The gating helper was renamed in this build; several unrelated functions share its minified name, so what it actually checks is not resolved here.

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