+# governance.yml — single wrapper that calls the shared estate governance
+# bundle in hyperpolymath/standards instead of carrying ~8 local copies.
+#
+# Replaces (deleted in verisimiser#59):
+#   quality.yml, guix-nix-policy.yml, npm-bun-blocker.yml, ts-blocker.yml,
+#   security-policy.yml, rsr-antipattern.yml, wellknown-enforcement.yml,
+#   workflow-linter.yml
+#
+# Load-bearing workflows stay standalone in this repo:
+#   rust-ci, codeql, dependabot-automerge, release
+# (plus repo-specific gates dogfood-gate / static-analysis-gate and the
+#  mirror/pages/scan plumbing, which have side effects or no PR noise).
