-The Community Manager is responsible for establishing, developing, and sustaining the Coulomb Society as an active community around Coulomb.social.
+`role-engine` is a versioned catalog for reusable organizational and operational
+role definitions. It keeps the shared model and multiple roles together so each
+role does not require its own repository.
+
+The first role is [Community Manager — Coulomb Society](roles/community-manager.md).
+
+## Repository layout

+```text
+INTENT.md                    repository purpose and boundaries

+
+The repository is documentation-first. A common schema, validation, rendering,
+or assignment tooling may be added only when concrete consumers require it.
+
+See [INTENT.md](INTENT.md) for the draft direction.
