# No live database is needed here — every Payload-backed route in this
# app is force-dynamic, so `next build` never touches Postgres. These
# are dummy values only so a real config error (a missing secret) is
# never silently masked by CI happening to run without one.
#
# NODE_ENV is deliberately NOT set here: `npm ci` treats a production
# NODE_ENV as `--omit=dev`, which would skip eslint/typescript/etc. and
# break Lint/Typecheck/Test. It's set below, scoped to the Build step.

# Builds once per commit that lands on main and has passed the checks
# above, and pushes it to the registry tagged by commit SHA. release.yml
# (triggered by a version tag) never rebuilds — it only promotes this
# exact, already-tested image to the release tag + `latest` and deploys
# it. This guarantees byte-for-byte that what gets deployed is what CI
# verified, and makes tagging a commit that never passed CI on main fail
# loudly (no image to promote) instead of silently rebuilding from
# source and skipping the checks.

# The anouma-runner runs as a Docker container itself (gitea/runner:3),
# with the host's docker.sock bind-mounted in but no `docker` CLI binary
# of its own — a job with no `container:` here runs directly inside that
# minimal runner image and gets "docker: command not found".
#
# A plain `docker:27-cli` image (Alpine, no Node.js) doesn't work either:
# actions/checkout@v4 is a JS action and needs a Node runtime in the job
# container, which that image doesn't have — it fails at Checkout with
# exit 127. Using a Node image as the base guarantees Node is already
# there (same reason the `test` job's node:22-alpine works), and the
# Docker CLI is added via apt. The runner auto-mounts the same host
# docker.sock into this container (sibling containers — see
# container.docker_host in the runner's config.yaml), so `docker
# build`/`push` operate on the host's real Docker daemon. release.yml's
# promote-and-deploy job uses the same setup, for the same reasons.

# Gitea Actions' runner is protocol-compatible with GitHub Actions,
# so step commands use the same $GITHUB_OUTPUT / $GITHUB_ENV
# mechanism (the `gitea.*` vs `github.*` expression contexts are
# just aliases of each other for `${{ }}` templating).
#
# The tag name (github.ref_name / $GITHUB_REF_NAME) is
# attacker-influenced: anyone with tag-push rights controls it, and
# git allows shell metacharacters in tag names. It's read here via
# the automatic $GITHUB_REF_NAME env var rather than `${{ github.ref_name }}`
# so its value reaches bash as data (argv/envp), never spliced into
# the script text — `${{ }}` expressions are substituted into the
# YAML before bash ever sees the script, which is what makes
# interpolating attacker-controlled values that way a script-injection
# vector (arbitrary code execution in a job that holds the registry
# and production deploy credentials).
