+// #9320 — Tunnel exposure: /v1/models leaks full model catalog without an API key
+//
+// Regression guard: when management auth is configured (isAuthRequired === true),
+// GET /v1/models must require an API key or dashboard session. Anonymous requests
+// should get a 401 status, not the full catalog.
+//
+// Before the fix, `requireAuthForModels` defaulted to `undefined` in settings,
+// and `undefined !== true` evaluates to `true`, so `getModelCatalogAuthRejection()`
+// returned null (pass-through) on every request — leaking 115+ model entries to
+// anonymous callers.
