 ## Authorization
 
-The API performs two levels of authorization:
-
-1. **Authentication**: Optional Auth0 JWT token validation
-2. **Blob Restriction**: Neo4j query to check if blob belongs exclusively to restricted branches
+Access control is limited to blob restriction: a Neo4j query checks whether the
