Use docs/gitea-actions-runner-substrate.md as the authoritative runbook. The templates here are intentionally examples because the final host paths, installer, and generated act_runner config must come from the attended runner host.

Files:

act-runner.env.example documents the non-secret environment shape and the approved token file reference.
act-runner.service.example is a systemd service skeleton for a binary act_runner installation.
act-runner.openrc.example is an OpenRC service skeleton for Alpine-style hosts such as haskelseed.
act-runner-haskelseed.openrc.example matches the current haskelseed registration layout, where /root/.runner already exists and act_runner runs from /root.

Do not commit .runner, generated configs containing host-specific state, token files, logs with secret material, or downloaded runner binaries.
