# CI for the self-hosted GitLab that replaced GitHub Actions when the account
# was suspended on 2026-09-20. This is a port of .github/workflows/ci.yml and
# publish.yml, which are kept in the tree for reference and for the day the
# appeal succeeds.
#
# Every `image:` here is pinned to a digest, with the tag it belonged to in the
# trailing comment. That is the direct replacement for the SHA-pinned `uses:`
# in the Actions workflows: GitLab has no equivalent of an action allowlist, so
# the only thing standing between this pipeline and whatever the publisher
# pushes to a tag next is the digest. Read the comment for the version; the
# digest is what runs. Do not "simplify" one back to a bare tag.
#
# The runner is a group runner on Web_Host with the host docker socket bound
# in, reached over the internal container network rather than
# https://git.coffeylabs.org -- that name is Cloudflare-proxied on the Free
# plan, which caps request bodies at 100 MB and would break artifact uploads.

variables:
  # Jobs talk to the registry directly on its DNS-only name, never through the
  # proxy, for the same 100 MB reason.

# Tag-driven, replacing the release -> publish workflow_call chain. GitHub
# needed that dance because a release cut with GITHUB_TOKEN raises no event;
# GitLab has no such rule, so a tag pipeline is enough.
#
# arm64 is built under QEMU on this amd64 host, not on a native runner as
# GitHub's free `ubuntu-24.04-arm` did. It is slow -- tens of minutes for the
# npm install and Vite build through instruction translation -- which is
# tolerable for a weekly tag and would not be for every push. That is why this
# job is tag-only. If arm64 ever starts timing out, the fix is an arm64 runner,
# not dropping the platform: TrueNAS and Unraid users pull it.
