/**
 * Unit Tests — 图执行结果桥接进 memory.md（36 号文档：Innovator/Dream 训练闭环可行性调研）
 *
 * 36 号文档实查发现的头号阻塞项：`graph-engine.js` 从不写 `memory.md`（唯一写入路径是
 * 人类对话 `agent-chat.js`），导致 Dream 每日扫描时，org/work graph 里真正干活的专业节点
 * （`prd-planning`/`coder`/`benchmark-validator`……）的 memory.md 永远是模板空壳——不是
 * "原料脏"，是压根没有原料。本文件锁的是补上的桥接点（`runClaimedNode` 结算之后调用
 * `recordNodeOutcomeMemory`）：
 *   ① 真实派发 + 本体已雇佣（bodyDir 存在）+ fail(body_not_ready) → 写一行摘要
 *      （借道 body_not_ready 端到端验证整条 isRealDispatch 真实链路——它跟其它"真派发"
 *      场景一样满足 agentExecutor===defaultAgentExecutor，却在真正调用 CLI 之前短路，
 *      是全仓库唯一能不起真 CLI 就摸到 isRealDispatch===true 的路径，35 号文档同款手法）
 *   ② 本体已雇佣，但 bodyDir 不存在 → 不写，避免测试夹具/未雇佣本体把假地址灌进
 *      真实 system/agents/ 目录（与 missingBody 同一条判据，多一层防线）
 *   ③ 注入假 executor（全仓库其余用例的常态）→ 不写，不干扰任何现有测试
 *   ④ `recordNodeOutcomeMemory` 直调：success 一行的格式化（advanceOne 端到端摸不到
 *      这条分支——isRealDispatch 为真时 else 分支会走真实 defaultAgentExecutor，起真 CLI，
 *      不适合单测；直调覆盖纯格式化逻辑，属于"最小可运行检查"）
 *
 * 隔离手法同 graph-engine-body-not-ready.test.js：monkeypatch 模块级活引用
 * （`locator.missingBodyDefinition` / `locator.bodyDir` / `memoryService.appendToMemoryMd`），
 * 不碰真实 system/agents/ 目录、不做真实文件 I/O。
