Instance Method Details

#call(comment_ids:, enforce_limit: true, auto_select: true) ⇒ Object

Creates a new topic with copies of the selected comments. Returns the new Topic. enforce_limit: false bypasses MAX_BRANCH_COMMENTS for system-initiated full-history copies (e.g. Drop Trigger) where the UI’s selection cap does not apply. auto_select: false omits user_id from the topic-created broadcast so background/system branches do not hijack the owner’s current selection.
