Probe the artifacts / probe (push) Successful in 5s
The release takes four minutes to reach the upload and fails there on a check the action makes before any request leaves the runner. The probe asks the same questions in seconds: what the runner puts in the GITHUB_ names, whether a step-level env reaches a JS action at all, and which of v3 and v4 gets an artifact through.
