+# scripts/pre-pr-check.sh
+#
+# Local secrecy linter for PR body / title / branch name before `gh pr create`
+# or `gh pr edit --body-file`. Mirrors .github/workflows/secrecy-check.yml so
+# failures surface locally instead of being caught by CI after the PR opens.
+#
+# Usage:
+#   scripts/pre-pr-check.sh --body-file /tmp/body.md [--title "..."] [--branch "feat/..."]
+#   scripts/pre-pr-check.sh --body "inline body text"
+#   scripts/pre-pr-check.sh --stdin < body.md
+#   scripts/pre-pr-check.sh --scan-sources           # same scan CI does for firstdata/sources
+#
+# Exit code: 0 = clean, 1 = confidential term found.
+#
+# Keep the BANNED_TERMS list in sync with .github/workflows/secrecy-check.yml.
