/**
 * Unit Tests — subgraph 节点结算 → workgraph-planning 自己的 memory.md 桥接（36 号文档追加）
 *
 * 背景：36 号文档真实回归发现 `workgraph-planning` 的图形状裁剪判据现在只有"允许裁剪"
 * 没有"具体判据"（单页静态网站任务原样照抄 planner.json 全部 5 节点，一个都没砍），而它
 * 自己完全没有可积累的历史——阶段一的 `recordNodeOutcomeMemory` 桥接明确排除了 subgraph
 * 节点（那是给 agent_call 节点记的，subgraph 节点没有对应的"真实执行"概念）。
 *
 * 本文件锁的是补上的那半：subgraph 节点结算（= 它规划出的子 work graph 最终收敛）时，
 * 把"这次规划的图跑得怎么样"记进 `workgraph-planning` 自己的 memory.md（不是宿主 org node
 * 的 `ctx.systemAgentId`，那是宿主自己的身份，不是真正执行规划的 agent——规划本体全局唯一）。
 *
 *   ① 真实规划（`planWorkGraph === defaultPlanWorkGraph`）+ success → 记 "success"
 *   ② 真实规划 + fail(reason) → 记 "fail: <reason>"
 *   ③ 注入假 planWorkGraph（全仓库现有 subgraph 测试的常态，见 graph-engine-revive-parent.test.js
 *      的 buildParentWithFailingChild）→ 不记，不能因为这次改动就把假地址写进真实
 *      system/agents/workgraph-planning/ 目录
 *
 * ①②借道直调（不必真起 CLI 触发 planWorkGraph===defaultPlanWorkGraph 才能验证格式化），
 * ③走完整的 subgraph 结算流程（复用 graph-engine-revive-parent.test.js 的建图手法），
 * 确认现有"全仓库 subgraph 测试都注入假 planWorkGraph"这条约定下这个新桥接确实按兵不动。
