-**Absence is the signal, and it is a real one.** Both planes set a provider-level `npm` of `@ai-sdk/openai-compatible` in `models.dev`, and **no model declares it explicitly**: 0 of 82 on Zen, 0 of 30 on Go. A model that speaks the completions shape simply omits `provider.npm` and inherits it. So "no SDK" does not mean "unknown"; it means _the provider default_, which is the protocol the route was itself registered with.
+**Absence is the signal, and it is a real one.** Both planes set a provider-level `npm` of `@ai-sdk/openai-compatible` in `models.dev`, and **no model declares it explicitly**: 0 of 82 on Zen, 0 of 31 on Go.

So "no SDK" does not mean "unknown"; it means _the provider default_, which is the protocol the route was itself registered with.
 
 That is why the servability check treats `undefined` as servable, and why `@ai-sdk/openai-compatible` is deliberately **not** in `PROTOCOL_FOR_SDK`: listing it would record the default as though it were an override. The coverage guard still covers the case where a model declares it explicitly. None do today, and if one did, the test would name it rather than drop the model.
