Tag pushes ignore paths: filters, so a release tag spuriously rebuilt the unchanged CI image and re-ran the gate on a commit the branch push already gated. Add branches: ['**'] to both push triggers — tag pushes no longer fire them (release.yaml owns tags). Pushing commits + a tag together still gates the commits via the branch push.

# Builds the nix CI toolchain image (.gitea/ci-image/Dockerfile) and pushes it
|
|
# to the Gitea registry. The gate (ci.yaml) runs *inside* this image, so this
|
|
# workflow is the gate's prerequisite. It only needs to run when the image's
|
|
# inputs change — the Dockerfile, the flake, or the toolchain pin — plus on
|
|
# manual dispatch.
|
|
#
|
|
# DinD pattern: plain docker:27-dind (one of the tested ci-test samples). No
|
|
# registry proxy here — the runner's containers have direct internet egress
|
|
# (the ci-probe run cloned github.com and pulled docker.io with no proxy), and
|
|
# this image's RUN steps fetch from apt + nixos.org, which the proxy isn't
|
|
# guaranteed to forward. The dind-cached:local + REGISTRY_PROXY_HOST variant is
|
|
# a later speed optimisation for base-image pull caching, not needed for green.
