`canvas_updated` 包含 `canvasId`、`operation`、`callId`、`actions`、可选的 `preview`/`text` 和 `canvasPatch`。`canvasPatch` 为 `{ canvasId, updatedAt, nodes: [{ before, after }], connections: [{ before, after }] }`；新增对象的 `before` 为 `null`，仅包含有变化的节点和连线。当前工具不开放删除。节点 action 保存操作、节点 ID、执行前标题、类型、修改字段和可选的修改后标题；引用 action 同时保存来源与目标节点 ID、标题和类型，不要求前端从内部 ID 猜测对象。`callId` 用于合并同一画布操作的工具完成消息。 - 前端对增量按 40ms 窗口合批，三方合并远端基线、当前 Store 和编辑器，正常完成 / 失败无需全量 GET；保留无关节点编辑、拖动与视口，同字段冲突、删除或新任务绑定不强行覆盖。只有事件缺口、断流、增量冲突或没有增量的事件源需要全量校准，同一画布协调器最多每秒发起一次，单请求在途，期间重复通知合并为一次尾随校准。已识别增量协议后，相邻 `tool_failed` / `run_failed` 不重复触发整图刷新。 -
