Launch an ordinary finite local workload as a durable detached process job, then release the assigning Codex turn instead of monitoring it. Use proactively for downloads, builds, test suites, evaluations, benchmarks, inference/model A/B runs, data jobs, and repairs whose underlying work may exceed 60 seconds or has uncertain duration. The user-visible parent must launch the job directly; never delegate local process execution or monitoring to a subagent.
