Function model_rung 

const fn model_rung(
    ctx: &ModelContext,
) -> (Option<&InferenceConfig>, Option<&InferenceConfig>, &'static str)

Which rung the model’s stored defaults occupy, and the name that rung carries — both decided by DefaultsOrigin in one place, so resolution and its labelling cannot disagree.

Exhaustive on purpose — see the twin in resolve_with_profile_explained. A catch-all here would rank any future unreviewed origin above global settings, which is precisely backwards.

The name was the static "model (auto-detected)", which lied in the debug line and the audit’s provenance strings whenever the occupant was a published recipe — and would have credited gglib’s guess for a tune sweep’s winner the same way.
