+name: Security Gate
+
+# Reusable (workflow_call) gate, called as the FIRST job of each CI workflow;
+# their real jobs declare `needs: gate`. Does NOT scan — the single scan runs in
+# security-scan.yml. This poller only decides whether to let its caller proceed:
+#   - non-PR event or trusted author -> proceed immediately
+#   - untrusted PR -> wait for the `Security Scan` check on the head SHA and
+#     MIRROR its conclusion (success -> proceed; failure -> fail, skipping the
+#     dependent CI jobs).
+#
+# The scan (security-scan.yml) is blocking: a finding fails the `Security Scan`
+# check, which this poller mirrors to block dependent CI. Splitting scan from
+# gate runs the scan once, not once per workflow. The trust decision is read
+# from `main` (should-scan.sh).
