The pending OkTest check is now green. The original compatibility suite passed, but its status reporter failed when the GitHub OIDC token request returned Gateway Timeout. Retrying only the reporter required a fresh prepared check, so the complete workflow was rerun. Attempt 3 passed the compatibility suite and successfully reported the result: https://github.com/openai/ok-test/actions/runs/40232581795/attempts/3 . No Python test or SDK code changes were necessary.
