@denizguney This seems quite specific. Is it provable that these values will hold under all conditions?

You're right, these values are currently specific to this sample test payload. Our main goal here is to isolate and verify the correct parsing and type safety of the StatusPayload structure. However, I can make the test more robust or document that this is strictly a deterministic validation for this specific mock fixture. Let me know if you'd prefer a more dynamic approach or if adjusting the fixture assertions works best!"
