Immediately after creating a User Story or Issue, call `assignUserStoryToSprint` / `assignIssue` / `addIssueToSprint` to set the current sprint and owner before treating the item as active. Tasks have no assignee or sprint tool at all — track Task ownership and sprint through the parent User Story instead.
