+name: Uncurated page advisory
+
+# Advisory ONLY. Comments on a PR that adds English pages which are not in the
+# translation curated set, so the translation backlog it creates is visible while
+# someone is still looking at the PR — instead of surfacing weeks later on the
+# dashboard, or not at all.
+#
+# This deliberately does NOT fail the PR, and there is deliberately no rule that
+# every new page must be curated. Curation is an editorial commitment (ZecHub
+# then maintains that page in 18 languages, indefinitely) and it is not the
+# contributor's call. A blocking check would also be worse than useless: faced
+# with a red gate, the fix that makes CI pass is to add the line, which creates
+# 18 items of real work with nobody having decided the page deserves them. That
+# is how a backlog grows silently, which is the exact problem this is meant to
+# expose. `curated ⊆ site` is the invariant; `site ⊆ curated` is not, by design
+# (see translation/check-invariants.mjs).
+#
+# SECURITY — why pull_request_target, and why it is safe here:
+# Most PRs to this repo come from forks, and a plain `pull_request` trigger gets
+# a read-only token for those, so it cannot comment. pull_request_target runs
+# with the base repo's token, which is only safe if PR code never executes. This
+# workflow therefore:
+#   * checks out nothing from the PR (no `ref:` override, no PR checkout at all),
+#   * runs no build, no install, no script from the PR,
+#   * reads the PR only as DATA through the API — the file list, and the text of
+#     translation/curated-pages.txt at the head sha.
+# Do not add a checkout of the PR head or any step that runs PR-authored code.
