Interface CheckpointMetadata

Lightweight descriptor stored alongside each persisted checkpoint snapshot. Used by the runtime to enumerate and restore checkpoints without deserialising the full GraphState payload.

interface CheckpointMetadata {
    id: string;
    runId: string;
    graphId: string;
    nodeId: string;
    timestamp: number;
    stateSize: number;
    hasMemorySnapshot: boolean;
}
