Debugging and Error Handling
Seven items on telling failures apart. The first fact does most of the work: refusals, truncations and paused loops all arrive on a successful response, so a handler wrapped around exceptions reports nothing while users file tickets. Read the stop reason before the content. The second is that a rejected request fails identically forever, which turns backoff around it into a queue that never drains. Capture the request identifier at the moment of failure, because a prompt cannot be traced afterwards.

Domain 4: Eval, Testing, and Debugging
This domain is 2.6% of a scored form, one question of the 53, and this objective is the whole of it. Drill the whole domain to walk the same items in one pass.
One objective is a narrow slice. A full-length timed mock is what tells you whether the whole thing holds together.
