 label and ordering-only changes preserve conversational continuity.
 
+Exactly one active role per Organization is the default used when a project
+group is first bound. The default is configuration data, not a hard-coded role
+name. Roles are selected through the Hub project console; role ids are not
+public slash commands. A project participant may change the group's shared
+selection only when both `agent.trigger` for the project and `role.trigger` for
+the target role authorize that actor. The selection affects every participant's
+future messages, while already accepted work keeps its frozen role.
+
+Hub slash commands are a closed control-plane protocol. Unknown commands fail
+explicitly and are never downgraded to Agent text. Claude SDK session commands
+are invoked only through typed Hub actions. In particular, compaction resumes
+the selected role session and sends the exact `/compact` prompt without
+prepending Feishu context.
