// The Cline OpenAI-Compatible contract verifier ships as a partner-facing
// self-check. Its OFFLINE mode runs the full assertion suite against an
// in-process mock that emits the exact OpenAI-compatible shapes Cline needs.
// A green offline run proves the assertions are internally consistent — if
// someone breaks an assertion (or the mock), this test catches it in CI
// rather than letting a partner discover a bogus verifier.
