/**
 * #7622 — no-auth provider "Excluded Models" field is stored + enforced at
 * dispatch time (src/sse/services/auth.ts) but IGNORED by the auto-combo/fusion
 * candidate pool builder (`getNoAuthCandidates()` in
 * open-sse/services/autoCombo/virtualFactory.ts). An excluded no-auth model must
 * never be advertised/selected in `auto/*` combos in the first place — it should
 * only fail over after being picked instead.
