+## Roles sync (pass 6): event names, failed sentences, categories
+
+Event names are present tense, as the backend emits them: role.create, role.edit, role.delete, role.reassign, user.change_role, user.transfer_ownership. The outcome is a field; a failed event keeps its name and uses the failed sentence.
+
+| Event | Sentence | Failed sentence |
+|---|---|---|
+| role.create | Role Contributor created | Failed to create the role Contributor |
+| role.edit | Role Contributor edited | Failed to edit the role Contributor |
+| role.delete | Role Intern deleted | Failed to delete the role Intern |
+| role.reassign | Moved 3 members from Intern to Writer (one member: Moved 1 member from Intern to Writer) | Failed to move 3 members from Intern to Writer |
+| user.change_role | Ines Duarte's role changed from Writer to Content lead | Failed to change the role of Ines Duarte |
+| user.transfer_ownership | Ownership transferred from Marta Alves to Jonas Weber | Failed to transfer ownership to Jonas Weber |
+
+Failed template: "Failed to {verb} {object}". A failed row shows the Failed badge after the sentence; the details panel shows "Why it failed" with the reason from the API.
+
+Category filter values: Articles, Media, Users and invites (was "Users & invites"), Roles (new), API keys, Authentication, System. French and the failed sentences for every event are in screens/roles.md, group 8 and the table "Activity events: failed sentences, EN and FR". Frames: Roles board, group "8 Activity".
