+# task check -> security:gitleaks enforces this in CI, but CI is after the
+# push. This catches a staged secret before it ever leaves the machine --
+# the infra#39 rotation pass found exactly this class of leak (a printed
+# credential, committed, archived into git) and there was no local gate to
+# have caught it. Mirrors infra's own .githooks/pre-commit (infra#326).
+#
+# Enable once per clone:   git config core.hooksPath .githooks
+# Bypass if absolutely needed: git commit --no-verify
