// #11180 regression guard: a custom OpenAI-compatible connection pointing at a
// keyless local backend (llama.cpp / Ollama / vLLM started without an API key)
// carries no apiKey, no OAuth token and no provider-specific session data, so
// `hasUsableConnectionCredential` dropped it from `validConnections` before the
// auto/* candidate pool was built. The connection was active, tested and synced,
// yet structurally invisible to auto-routing with no log line and no UI hint.
//
// Keyless is the NORMAL configuration for a self-hosted backend, so a custom
// compatible connection must stay eligible. This gate is one step later than
// #5873 (registry-absent defaultModel fallback), whose guard still passes.
