// Regression test for #3200 — imported/custom models on noAuth providers were missing
// from GET /api/v1/models (and therefore from the Playground model dropdown), while
// BUILT-IN and CUSTOM models on regular auth providers showed up fine.
//
// Root cause: the custom-models loop in catalog.ts gated every model through
// hasEligibleConnectionForModel(getConnectionsForProvider(...)). noAuth providers
// (e.g. theoldllm / alias "tllm") have NO DB connection rows, so getConnectionsForProvider
// returns [] and hasEligibleConnectionForModel([]) === false → the model was dropped.
// Built-in models survived because they go through providerSupportsModel(), which has a
// noAuth bypass (#2798). This test asserts an IMPORTED model on a noAuth provider appears.
