# Gitea Actions caution, learned elsewhere in this org: never leave an empty
# template expression anywhere in a `run:` script, not even inside a comment.
# The runner silently SKIPS the whole step without failing the job, and the
# problem is invisible in the workflow list.

        # policy and the answers given to Google cannot drift apart. This re-runs the
        # generator and fails if the committed copy differs.
        #
        # It runs before the build because it needs neither one: it is the cheapest check
        # here and the one whose failure is easiest to act on.

        # limit, cap, validation, duplicate, removal.
        #
        # The first thing in this repository that the other checks cannot see. They all read
        # the built output, and none of this appears there: a honeypot that has stopped
        # working produces a build that is identical in every way to one where it works.
        #
        # The test file is NAMED rather than the directory passed. `node --test test/` fails
        # on Node 22 with MODULE_NOT_FOUND — directory mode is not portable across the
        # versions this org runs, and this workflow pins 22 while developers are on 24, so
        # the shorter form would pass locally and break only here.

      - name: Sidebar
        # PLAN.md §12, phase 8. src/config/sidebar.mjs holds two trees — the one Starlight
        # renders and the one §10 planned — and they must agree on groups, labels and
        # ORDER. Order because the order of "Getting started" IS the installation path.
        #
        # While pages were being written the planned tree was a checklist; now that every
        # page exists it is a hand-maintained second copy, and it had already drifted
        # unnoticed (phase 7 added Content under D37 and never updated it). Nothing caught
        # that because nothing read it.
        #
        # No token, no network, no build — so it runs early and fails fast.

      - name: Screenshots
        # PLAN.md §12, phase 9 (D45). src/data/screens.mjs is the one list of what the site
        # shows of itself: every entry must have a file, at the size the markup declares, and
        # every file must have an entry. The size half is the one that repays the check —
        # a re-capture taken at the wrong viewport looks perfectly fine on its own and only
        # reveals itself as a page that reflows while it decodes.
        #
        # No browser and no game server: the capture tool is an authoring script whose output
        # is committed, exactly like the brand assets, so CI only reads what it produced.

        # RunicGateway repository points at a branch path rather than a commit permalink.
        #
        # It runs AFTER the build, and that ordering is the design rather than a
        # convenience: it reads the built HTML, so links assembled from data files and
        # template literals are checked as the strings they actually become. A source scan
        # would see an expression and skip most of what phase 4 added.
        #
        # No network: the outbound rule is about the shape of a URL, and a build that
        # fails because some other host is slow is a check people learn to ignore.

        # PLAN.md §12 — every version, protocol number and bundle tag is re-read from
        # its authority over the Gitea API and must agree with src/data/platform.json.
        #
        # This needs a token that can read the OTHER repositories in the org: link,
        # servuo-plugins, website and installer. The automatic per-run token is scoped
        # to this repository alone and 404s on all four, so the job uses the org-level
        # REGISTRY_TOKEN, which already exists and already carries the right scope.
        #
        # The secret is named for the registry; the script reads GITEA_TOKEN. Mapping it
        # here rather than renaming either side keeps the script's interface honest — it
        # wants a Gitea token, not this org's particular secret.
        #
        # It runs last, and it is the only step that touches the network, so a Gitea
        # outage cannot mask a real failure in the build.

        # Compose file and an environment file the reader copies without leaving the page,
        # which is the one place this site knowingly keeps a copy of another repo's file.
        #
        # So the copy is checked in BOTH directions: every value it states must match
        # website's own docker-compose.yml and .env.example on main, and every service and
        # variable THEY have must be either included or listed as deliberately omitted with
        # a reason. A new variable upstream turns this repo red until someone decides
        # whether a first install needs it — the same intent as the facts check above.
        #
        # Same token, and for the same reason: it reads another repository in the org.

        # PLAN.md §12, phase 8. The Reference section names things — every environment
        # variable, config key, installer command, visibility rung and canonical document.
        # §1 forbids re-specifying a contract, and this is what makes writing the NAMES
        # down safe anyway: each list is a SET comparison against the repository that owns
        # it, in both directions.
        #
        # The second direction is the one that earns its keep. A reference page does not
        # usually rot by describing something that vanished — it rots by quietly not
        # mentioning the three things added since it was written.
        #
        # Descriptions are deliberately NOT checked; nothing here can know whether a
        # one-line summary is still true, so it does not pretend to.
        #
        # Same token, and for the same reason: it reads five other repositories in the org.
