+/**
+ * TDD regression for #15307: Xiaomi MiMo "import models" served the 2-entry
+ * hardcoded registry seed with "API unavailable — using local catalog", even
+ * though the upstream `GET /v1/models` answers with a full live catalog
+ * (8 models on the token-plan host, including mimo-v2.6-pro / mimo-v2.6-flash
+ * and the ASR/TTS variants) and chat completions work against the same key.
+ *
+ * Root cause: `xiaomi-mimo` / `xiaomi-mimo-token-plan` are keyed OpenAI-style
+ * providers with a real registry `baseUrl`, but are not classified by any
+ * live-fetch branch of the import route — they are not `openai-compatible-*`,
+ * not self-hosted, and were not in NAMED_OPENAI_STYLE_PROVIDERS. So the route
+ * never probed the upstream `/models` and fell through to the registry's tiny
+ * hardcoded `models[]` (2 entries), while inference kept working through
+ * DefaultExecutor. Same case as #4249 (vercel-ai-gateway), #4202 (zenmux) and
+ * #3976 (llm7/byteplus).
+ *
+ * Fix: add `xiaomi-mimo` and `xiaomi-mimo-token-plan` to
+ * NAMED_OPENAI_STYLE_PROVIDERS so the route does a live `<baseUrl>/models`
+ * fetch, falling back to the local catalog only when the upstream fetch fails —
+ * import never breaks.
