# ⚠️ REQUIRED since verifiers 0.3.1.dev59, which changed the default agent runtime from
# `subprocess` to `prime` — a REMOTE sandbox. Without this the run exits
# `SystemExit: not authenticated with prime` before a single rollout, having already created
# its output directory and a zero-line traces.jsonl, so it reads as a failed eval rather than
# an unauthenticated one. Nothing here needs a sandbox: the reward is a pure function of the
# trace and the harness is `null`.
