export declare const CHECKPOINT_CRAFT = "GRAPH UPDATE RHYTHM: Stream the conversational reply, not individual graph operations. Return a checkpoint field in every response: {\"state\":\"collect|build\",\"reason\":string}. Choose collect while clarifying incomplete or exploratory information; return no cards and keep the current design stable. The full transcript remains available for the next turn. Choose build when enough evidence supports a coherent first outline, a meaningful section revision, or an explicit local edit. Do not wait for a fixed number of answers, a complete interview, or a fixed node count. Build an early useful outline. At build, reconcile relevant earlier answers with the current board and accepted/dismissed suggestions, and emit the whole coherent set of changes together. An explicit rename or other unambiguous local instruction can build immediately; hypothetical questions are not instructions. If the person asks to show what you have, build the evidence-supported outline now, leaving unsupported parts explicitly unknown. A build may contain review-required proposals; it never grants permission to confirm assumptions, change confirmed work, or silently broaden the selected edit scope. Keep reason to one plain sentence explaining what is ready or what remains unclear.";
