src/jev 3 个文件 515 行：判重、查冻结条款、查代码改动三个函数，九问问法和阈值照参考项目，只改说法和字段名，阈值注明未在新项目材料上校准，等真实数据。
新增 npm run test:jev（真实 Jev 三处各问一次）。vocab 加 JevJudgment。
ledger 表结构版本 3：callEnded 四种结局对上 agents，墙钟时间用 Measured（恢复时补写出错、原因"进程中断"、测不到）；退回、提交记录都带 jev。
config 加必填的 models.jev。

用户原话："这次就给提交记录加一个和退回记录同样的 Jev 判断字段"；"墙钟时间改用 Measured，恢复时写出错加测不到（原因'进程中断'）"。

 - 任务书 06（workspace）：src/workspace 2 个文件、205 行，`npm test` 284 条通过（workspace 10 条，真实 git）。版本号是目录树编号，存版本自己列文件加 hash-object，取出用 ls-tree 加 cat-file（实测 `git archive` 会按树里的 `.gitattributes` 丢文件、改换行符），git 子进程另关掉系统和用户的 attributes 文件（实测只关配置时 `~/.config/git/attributes` 仍会被读）。tasks 的 task.json 加必填的 `unversionedNames`，`protectedFiles` 删掉 solution.json。全新上下文审阅一轮：两处偏离都实测成立；采纳一条（写明空文件增删、只改可执行位没有块），其余不改。结构.md 第八部分补了 workspace。
 - 任务书 07（agents）：src/agents 4 个文件、681 行（预期按用户决定改为 600–700，超出部分是任务书第四部分要保留的三处提交处理、读代码分段和会话核对，没有新增专门路径），`npm test` 293 条通过（agents 9 条，其中 1 条经真实 Pi 会话连本机假模型服务）。package.json 固定 `@earendil-works/pi-coding-agent`、`pi-ai` 0.85.1 并加 overrides（同参考项目）；新增 `npm run test:pi`（真实 glm-5.3，研究者先退回再收下、实验员写文件跑 shell 再交）。实测：glm-5.3 经 iomgaa 服务时，正文里没转义的半角双引号会在服务那一侧把参数截成合法但半截的 JSON，Pi 收到的原文本身合法，JSON 检查查不出（抓包确认）；提交工具说明里加了一句"引号用「」"，之后 12 份提交没再出现。结构.md 第七、八部分已更新。
