   routing rules to call `/api/v4/internal/cells/classify`.
 - The routing rules should use `prefix` as a way to speed up classification. During the compilation phase
   the routing service transforms all found prefixes into a decision tree to speed up any subsequent regex matches.
+- Some of the prefixes need to be Cell independent, example Personal Access Tokens prefix need to be organization bound and not Cell bound.
+  We want the ability to move an organization from 1 cell to another without changing the Personal Access Token or any other token.
 - The routing rules is ideally compiled into source code to avoid expensive parsing and evaluation of the rules
   dynamically as part of deployment.
