build / build-and-scan (push) Waiting to run
文档库：目录改为编号制（01-规范/02-架构设计/03-数据库/04-调整方案/
05-交接单/06-ops/07-scripts/08-skills/09-archive），顶层散文件归入 01-规范/；
INDEX.md 与 docs-manifest.json 重刷（档案 146 篇）；旧目录名引用全量对齐。
IM 线：src/im/**（SDK / hub / store / presence / ws / gateway-token）、
src/web/routes/im.ts、src/db/plugin-data/**、src/supervisor/plugin-assembly.ts
及对应 test/**。
插件线：poc/{im-agent-bridge,im-connection-gateway,im-conversation-tabs,
business-plugins-im,carbon-mcp-probe}、src/web/routes/{sessions,overlay-device}.ts、
src/net/relay/{device-grant,instance-credential}.ts。
仓库卫生：清出 40 个历史误入库 / 已改名文件（34 个交接单归档 + 6 个旧结构，
本地均有副本）；dsh-server-docs/.gitignore 补 tmp/；交接单不入库（政策）。

"""docs-shrink-guard.py — 防「共享文件被整文件重写抹掉别人的行」
|
||
|
||
为什么需要（2026-09-14 实测）
|
||
* `MEMORY.md` 被并行会话**整文件重写**，抹掉了本会话刚写进去的两行；
|
||
* 本库的规矩是「共享文件只用 Edit 精确替换，禁整文件 Write」—— 但**只靠人守纪律**，没有机制兜底。
|
||
⇒ 本脚本给"纪律"加一条**机械兜底**：记录每个文件的**行数快照**，下次运行时若某文件
|
||
**行数骤降**（默认 >30% 且绝对减少 >20 行），就把它当成"疑似被整文件重写"报警。
|
||
|
||
覆盖范围（两处共享热区）：
|
||
* 文档库 `dsh-server-docs/**/*.md`
|
||
* 工作区记忆 `.workbuddy/memory/*.md`
|
||
快照落在**库外**（`<工作区>/.workbuddy/cache/docs-lines.json`）—— 放库内会污染 `docs-sync-check` 对账。
|
||
|
||
用法
|
||
python3 07-scripts/docs-shrink-guard.py # 比对并报告（不改快照）
|
||
python3 07-scripts/docs-shrink-guard.py --write # 比对 + 刷新快照（改完文件后跑）
|
||
python3 07-scripts/docs-shrink-guard.py --baseline # 只建档不比对（首次）
|
||
python3 07-scripts/docs-shrink-guard.py --allow-shrink <路径子串> # 合法重构白名单（不报警）
|
||
退出码：0 = 无骤降；1 = 发现骤降（需人看一眼 diff）；2 = 用法错误
