+ * E2E coverage for the B17 provider cost metric calculation.
+ *
+ * The MiMo provider (src/api/providers/mimo.ts) computes `totalCost` from
+ * streamed `usage` chunks via `calculateApiCostOpenAI` and yields it as a
+ * `usage` stream item. Task.ts then persists it on the `api_req_started`
+ * cline message (`cost` field of ClineApiReqInfo) and forwards it to
+ * `TelemetryService.captureLlmCompletion`. This suite drives the built
+ * extension against a local OpenAI-compatible stub that returns a fixed
+ * usage payload and asserts the persisted cost matches the model's
+ * published pricing (inputPrice/outputPrice of mimo-v2.5-pro).
