+# Pre-push test gate. The deploy server only ever PULLS, so the real place to
+# stop broken code is right here — before anything leaves this machine.
+#
+# The suite needs no external database: integration tests spin up an in-process
+# PGlite database per worker (see tests/helpers/integration-setup.ts), so
+# `npm test` runs standalone. A real failure blocks the push; the run ends with a
+# compact copy-pasteable summary (scripts/test-summary.mjs).
+#
+# Install once:   git config core.hooksPath .githooks
+# Emergency skip: git push --no-verify
+#
