+# Deployment Gates
+
+## Minimum Gate Policy
+
+- `lint` must pass before `test`.
+- `test` must pass before `build`.
+- `build` artifact required for deploy jobs.
+- Production deploy requires manual approval and protected branch.
+
+## Environment Pattern
+
+- `develop` -> auto deploy to staging
+- `main` -> manual promote to production
+
+## Rollback Requirement
+
+Every deploy job should define a rollback command or procedure reference.
