@@ -54,6 +54,7 @@ Gameplay capabilities now include:
 - Role-aware authorization with admin role support (including admin user/role management)
 - Campaign deletion by campaign owner or admin (unlinks characters from the campaign and clears campaign log entries)
 - User deletion by admin also deletes campaigns owned by that user and unlinks all characters from those deleted campaigns
+- Play screen visibility is owner-scoped: only owned characters are listed, and private log entries are visible only to the roller
 - Campaign management owner labels use account display names (no GUID fallback rendering)
 - Character edit flow supports unlinking from campaigns (owner/GM/admin) and assigning to any existing campaign via expanded campaign options
 - Campaign management supports character deletion by character owner or admin
