message_sanitization.close_interrupted_tool_sequence and the turn_api_call repetition-loop exit each spelled the same hidden assistant row literal (content "", display_kind hidden, api_content _INTERRUPTED_PLACEHOLDER), and the conversation loop's redirect built it field by field. Add hidden_interrupt_placeholder_row() to the leaf placeholders module and use it at all three sites so the shape cannot drift between them. Gate rP finding 6 (reuse).
