 # Review Translations — Quality check on translation PRs
 # When a PR is opened/updated that carries the 'action-translation' label,
 # this workflow runs a quality review and posts a comment.
+#
+# Mirrors the upstream template in action-translation
+# docs/user/tutorials/connect-existing.md — keep it in step with that.

-# Serialise reviews per PR.

-# The sync action creates the PR and then applies its labels in a separate call,
-# so a single sync fires `opened` plus one `labeled` event per label, all within
-# a couple of seconds. Every one of those starts a full review, and the action's
-# "update the existing comment, else create one" logic is a check-then-act with
-# no lock — concurrent runs all observe "no comment yet" and each create one.
-# That is how PR #6 collected two independent review comments.
-#
-# cancel-in-progress is deliberately false. The labels are applied in one API
-# call, so event ordering is not guaranteed; if 'automated' arrived last it would
-# cancel the in-flight review for 'action-translation' and then skip its own job
-# via the filter below, leaving no review at all. Queuing instead means the first
-# run creates the comment and any later run updates it — one comment, always.
