# IMPORTANT — the currently inventoried server is Gitea 1.24.2, which *ignores* several keys used
# below. Per https://docs.gitea.com/1.24/usage/actions/comparison, its unsupported workflow syntax
# includes `permissions` / `jobs.<job_id>.permissions`, `concurrency`, and
# `jobs.<job_id>.timeout-minutes`. They are declared here deliberately, so the workflow is already
# correct on a supported release and on GitHub Actions, but on this server they are inert:
#
#   * `permissions:` does NOT restrict the in-job `GITEA_TOKEN`. Job-token permission controls,
#     repository/owner defaults, and server-side maximum-permission clamping arrive in the 1.26
#     feature line (https://docs.gitea.com/1.26/usage/actions/token-permissions). Until the server
#     is upgraded and configured, the token's authority is whatever the server grants — not what
#     this file requests.
#   * `concurrency:` and `timeout-minutes:` are NOT bounded-execution guarantees here. Cancellation,
#     timeout, and teardown must be enforced by the trusted runner provisioner/reaper.
#
# `persist-credentials: false` below is unaffected by any of this and is enforced by the action
# itself. See docs/development/security.md.
