+# Architecture Documentation Policy
+
+This project uses a Bible-style architecture documentation folder as the single source of truth.
+
+## Mandatory Rules
+
+- Record architecture decisions before or together with implementation.
+- Use English for architecture documentation.
+- Remove or update obsolete architectural guidance in the same change.
+- Keep non-Bible docs concise and reference the Bible instead of duplicating it.
