+## Reference Architecture
+
+MNPPI maintains current stack standards, delivery controls, and adoption guidance at [architecture.mnppi.org](https://architecture.mnppi.org/).
+
+GitHub Actions validates changes, and GitHub rulesets authorize merges.
+Cloudflare Workers Builds owns normal production builds and deployments.
