How to prove it during checking

Read-only check. Detection data burns after 5 minutes.

Then list models or run a lightweight probe: check whether models like Granite 4.0 Micro are visible and return stable evidence.
Finally record 400/401, error body, latency, egress IP, and reproducibility to separate balance, permission, route, or upstream issues.

Next action
