// #8082: the built-in `poe` provider (passthroughModels:true, no baseUrl field
// exposed in the UI) is routed through the generic OpenAI-style model-discovery
// branch, which resolves its base URL ONLY from
// `connection.providerSpecificData.baseUrl` OR `getRegistryEntry("poe")?.baseUrl`.
// There was no REGISTRY entry for "poe", so discovery always failed with
// {"error":"No base URL configured for provider"} even though the actual
// inference/validation path (src/lib/providers/validation/audioMiscProviders.ts)
// has always had a hardcoded "https://api.poe.com/v1" fallback and worked fine.
