DeepSeek Harness 的 C 盘逃逸监测与安全清理插件：把 AI 工具链的缓存与临时文件拦在 C 盘之外，并安全回收已经逃逸出去的那部分。
以原生 Cordis 宿主插件实现（Node.js，除 Node 内置模块外零运行时依赖），实现了 产品需求与技术规格文档 (PRD).md 的全部 Phase 1 + Phase 2 + Phase 3 需求。
0.5.0 · MIT · Node ≥ 20 · DSH ≥ 0.2.1-rc.2
实机截图：左侧是 Harness 侧边栏（「C 盘逃逸清理」高亮选中），右侧是它打开的玻璃面板 —— 统计卡、三级分类表、勾选与清理操作都在同一屏内完成。
PRD 的前提是「$DSH_HOME 已经在 E 盘，所以只剩下 C 盘的逃逸写入」。本插件分四层处理这个残留：
| 阶段 | PRD | 模块 | 状态 |
|---|---|---|---|
| 事前拦截 —— 环境变量劫持 | §3.1 | lib/env-hijack.js | 已实现，有实机证据 |
| 事中监控 —— C 盘写入监听 | §3.2 | lib/watcher.js、lib/process-tree.js | 已实现 |
| 三级分类 | §3.3 | lib/classifier.js | 已实现 |
| 事后清理 —— 安全删除 | §3.4 | lib/cleaner.js | 已实现 |
目录迁移 —— mklink /J 联接点 | §3.4 | lib/symlink-migrate.js | 已实现（Phase 3） |
CLI/TUI —— c-clean 命令 | §4 | lib/commands.js + lib/web-api.js + client.js | status/now/ui/migrate/unmigrate 全部可用 |
| 持久化 —— SQLite 状态库 | §5 | lib/state-db.js | 已实现（node:sqlite） |
会话结束静默清理 —— post_session_close | §7 | lib/session-hook.js | 已实现（Phase 3，默认关闭） |
Phase 3 的两项交付物都已落地：
mklink /J 联接点迁移（PRD §3.4/§7）——把一个顽固目录整体搬离 C 盘，并在原路径留下目录联接点，让写死路径的程序继续正常工作，而字节落在目标盘。支持撤销。post_session_close 静默清理（PRD §7）——会话结束时静默清扫 🟢 文件。宿主并没有这个事件名，钩子绑的是 session/disposed（详见下文「已知限制」第 8 条）。默认关闭（sessionCloseClean: false）。ui 以 Harness 侧边栏面板的形式交付，而不是终端 TUI —— 因为 Cordis 的斜杠命令无法渲染交互式组件。
dsh plugin 是官方入口：它是 pnpm 的前端，在 profile 目录内执行，并在安装成功后为每个声明了 dsh.bundle 的新依赖自动改写 dsh.profile.bundles。本包声明了一个（./cordis.patch.yml），所以会被自动注册为一个生效的 profile 层 —— 不要手改 profile 的 package.json 或 cordis.patch.yml，也不要在 $DSH_HOME 下创建包。
dsh plugin --profile <profile> add <指向本目录的绝对路径>
# 例如：dsh plugin --profile tauri add F:/work/dsh-c-cleaner
相对目录同样可用，会按当前工作目录解析：
cd F:/work && dsh plugin --profile <profile> add ./dsh-c-cleaner
这两种形式都装成 link 依赖，所以之后在源码目录里的修改会立刻反映到磁盘上。
dsh plugin --profile <profile> add dsh-c-cleaner
已发布：
dsh-c-cleaner@0.5.0，见 https://www.npmjs.com/package/dsh-c-cleaner。装出来的是^0.5.0的 registry 依赖，pnpm 会把它拷进 profile 的node_modules（不是软链），所以之后要升级得重新add一次。
dsh plugin --profile <profile> add github:wuyu1327083461/dsh-c-cleaner
dsh plugin --profile <profile> add file:<dsh-c-cleaner-0.5.0.tgz 的绝对路径>
路径请用 Windows 风格（file:C:/...），不要用 MSYS 风格（file:/c/...）—— pnpm 不接受后者。
plugin_manager 工具安装同样的安装，由 agent 会话驱动而不是 shell：
plugin_manager { action: "install_bundle", target: "<指向本目录的绝对路径>" }
替换一个已安装的副本需要重启 Harness 才能加载新的 JS 模块代际；首次安装可以通过 HMR 直接生效。
files 字段里必须有什么pnpm 会按照 files 数组来打包 git / tarball 依赖，所以 cordis.patch.yml 必须列在其中。缺了它，装出来的树里没有 patch 文件，安装会被拒绝：
dsh: installation rejected: ... failed to read overlay ... cordis.patch.yml: ENOENT
随后整体回滚 package.json、pnpm-lock.yaml 和 node_modules。路径安装和 link: 安装不经过打包，因此不受影响 —— 这也正是这个疏漏能长期潜伏的原因。
c-clean status # 只读汇总，不遍历磁盘
c-clean ui # 指向交互式面板（Harness 侧边栏）
c-clean now # 把所有 🟢 SAFE_TO_DELETE 清理进回收站
c-clean now --deep # 连同 🟡 CAUTION_CACHE 一起清理
c-clean now --force # 物理删除，不进回收站

c-clean migrate # 列出值得搬离 C 盘的顽固目录
c-clean migrate <dir> # 搬到 E 盘并留下目录联接点（PRD 3.4，mklink /J）
c-clean unmigrate <dir> # 撤销迁移，把数据搬回 C 盘
status 的输出，首行即 PRD §4 的约定格式：
🟢 可清理: 342.0 MB (128个文件) | 🟡 缓存驻留: 1.2 GB | 🔴 正在占用: 3个文件
环境变量劫持: ✅ 已生效 (9/9 变量) → E:\dsh_escape_cache
ui）斜杠命令无法渲染组件，所以 c-clean ui 返回一个指针加上实时摘要，真正的 UI 是 Harness 侧边栏里的 Client-slot React 面板。找侧边栏导轨上的 C 盘逃逸清理 图标：
面板是一个整页 main 槽位组件，数据来自宿主半侧的 JSON API：
| 端点 | 方法 | 返回 |
|---|---|---|
/c-cleaner/api/state | GET | {rows, hijack, escapeRoot, useRecycleBin, escapeWritable} |
/c-cleaner/api/refresh | POST | 重新轮询进程树，然后返回同样形状的快照 |
/c-cleaner/api/clean | POST | {report, rejected, rows} |
/c-cleaner/api/stale | GET | {count, bytes, scanned, kept} —— 有多少条跟踪记录会被今天的准入规则拒绝 |
/c-cleaner/api/purge | POST | 遗忘这些记录，然后 {forgotten, bytes, remaining, rows} |
/c-cleaner/api/migrate | POST | {path} → 搬到 E 盘并留下联接点：{result, migrated, rows, migrations} |
/c-cleaner/api/unmigrate | POST | {path} → 撤销一条已记录的迁移：{result, migrated, rows, migrations} |
/state 和 /refresh 故意返回完全一致的快照形状。早先让 /refresh 只返回 rows，结果刷新之后顶栏立刻显示「环境变量劫持未生效」—— 在面板最关键的那行状态上误报了一次逃逸根目录。
/stale + /purge）PRD §3.2 的噪声闸门（见下面「已知限制」第 1–2 条）只对从今往后监听器看到的写入生效。在那之前写入的记录会留在表里 —— 实机测量：2205 条绿色记录中的 1079 条、约 1.09 GB，绝大多数是 Windows SDK 安装包和属于其他软件的 Visual Studio DLL。它们删了并不危险（%TEMP% 里未加锁的文件），但「全选可清理项」/「清理全部可清理」会作用于全部绿色记录，一次点击就会把别的软件的安装包扫进回收站，同时把 PRD 真正要求展示的 dsh 记录埋在下面。
「清理过期条目」移除的正是这些记录，它只做记账：
classifyName()，准入规则只有一份实现，不会漂移成两份；SAFE_TO_DELETE 记录可选 —— 无论名字长什么样，🔴 或 🟡 记录永不被遗忘；credentials.json 不会被清掉）；GET /stale 只做计数，好让面板在用户确认之前先展示数量。
/clean 会删文件，而 127.0.0.1:3080 可以被本机任意页面访问。所以每个请求都必须通过 isTrustedApiRequest()（lib/web-api.js）：Host 必须是回环地址（或在 trustedHosts 中）、直接拒绝 sec-fetch-site: cross-site，其余情况要求 Origin 的主机名等于 Host 的主机名（并显式放行桌面壳自己的源 dsh-app://app）。回环请求但带上外来 Origin 同样会被拒绝 —— 实机验证：
# 实机，打到运行中的 harness
curl -H 'Host: evil.example.com' http://127.0.0.1:3080/c-cleaner/api/state -> 403
curl -X POST .../c-cleaner/api/clean -d '{"paths":["C:\\Windows\\System32\\kernel32.dll"]}'
-> rejected, deletedCount 0
第二条才是真正的护栏：面板只能清理插件自己已经跟踪过的东西。每个请求路径都会（大小写不敏感地）与持久化记录匹配，交给清理器的每条记录都从持久化列重建 —— 客户端伪造 {"category":"SAFE_TO_DELETE"} 也无法把 🔴 文件提级。test/_lead-phase2-api.mjs 正是用伪造请求体来断言这一点。
面板自己的传输走页面的目录基准而不是源根路径（client.js 里的 hostRouteUrl），因为以斜杠开头的 URL 会把自己钉死在源根上，放在反向代理的子目录后面就会 404。桌面壳里面页是 dsh-app://app/，壳的协议处理器会把非模块路径同源转发给宿主。
/c-cleaner/ui）上面那个 React main 槽位面板是两种渲染之一，第二种才是值得一看的。c-clean ui 还会打开位于 http://127.0.0.1:3080/c-cleaner/ui/index.html 的玻璃面板 —— 一个自包含文档（2650 行，零外部请求，无 CDN、无框架），由插件自己托管：
| 端点 | 方法 | 返回 |
|---|---|---|
/c-cleaner/ui/api/get_state | POST | 完整快照：环境变量分组、监听根、三级记录 |
/c-cleaner/ui/api/clean | POST | 扁平的 {ok, cleaned, skipped, freed_bytes} |
/c-cleaner/ui/api/migrate | POST | {ok, target, bytes_moved} —— 到 E 盘的联接点 |
/c-cleaner/ui/api/unmigrate | POST | 撤销一条已记录的迁移 |
/c-cleaner/ui/api/poll_events | POST | {cursor, events} —— ⚡实时捕获 通道 |
它被原样托管而不是改写成 React 组件，是因为一个 2500 行、已经充分验证过的界面手工移植过去，必然带来视觉漂移。lib/panel-ui.js 在第二个前缀（/c-cleaner/ui，最长前缀优先于既有的 /c-cleaner/api）上注册路由，并把它那套扁平方言翻译成本插件自己的 {ok, value} 信封与分类名 —— 文档本身一行都不用改，因为它自己的 REST_BASE='api/' 是相对路径，浏览器会相对文档所在目录解析。
玻璃面板有两个刻意的、承担关键职责的行为（lib/panel-snapshot.js）：
findCandidates 按 path.dirname 分组，会把 uv-cache/wheels/<1000 个 .whl> 变成 1000 条各自都拒绝迁移的记录。面板改成按监听根下的第一层目录分组，于是一条 🟡 记录 == 一个可迁移目录。realpath 会打印 E 盘路径，从而抹掉这条记录唯一要传达的事实 ——「已经打通了，但仍占着它的 C 盘位置」。实时通道是有界环形缓冲（index.js 中的 LIVE_BUFFER_MAX = 500），不是无限日志：面板只索取比上次游标更新的事件，长期空闲的会话不能让它无界增长。记录会在任何 autoClean 能删掉文件之前推进缓冲，所以即使文件下一秒就没了，面板仍会显示这次捕获。
PRD 的前提是「$DSH_HOME 已经搬到 E 盘，所以只剩下 C 盘的逃逸写入」。3.1 模块就是用来掐断新增逃逸的。
在这个 harness 里给子进程喂环境变量有两条路，而其中只有一条能带上 TEMP/PIP_CACHE_DIR：
ctx.shellEnv.register() 只贡献 DSH_* 命名空间的键（dsh-subprocess/lib/index.js:13 → const DSH_ENV_PREFIX = "DSH_"），带不了 TEMP。process.env 可以，因为每个 harness 子进程都是实时读取父环境来构造的：dsh-subprocess/lib/index.js:50-56 的 scrubbedParentEnv() 用 Object.entries(process.env) 构建子环境，只过滤匹配 /KEY|PASSWORD|SECRET|TOKEN/i 的名字，以及 DSH_ 开头的名字。所以插件只改 process.env，别的什么都不碰。已针对真实安装的 scrubbedParentEnv 验证，并带有反向对照：
=== 劫持之后 scrubbedParentEnv()（每个 harness 子进程继承到的环境）===
PASS TEMP = E:\dsh_escape_cache\temp
PASS PIP_CACHE_DIR = E:\dsh_escape_cache\pip_cache_dir
... 9/9 个被劫持变量都扛过了 harness 的环境清洗
--- 反向对照（证明清洗逻辑确实在跑）---
MY_FAKE_API_KEY present : false（期望 false —— 命中 KEY）
DSH_SHOULD_BE_STRIPPED present: false（期望 false —— DSH_ 前缀）
--- 端到端：真实子进程 ---
child cmd.exe saw TEMP = E:\dsh_escape_cache\temp
用 node test/_env-propagation.mjs 复现。
被重定向的变量（lib/config.js → DEFAULT_ENV_MAP）：TEMP、TMP、TMPDIR → temp；PIP_CACHE_DIR → pip；UV_CACHE_DIR → uv；HF_HOME → huggingface；TORCH_HOME → torch；NPM_CONFIG_CACHE → npm；PLAYWRIGHT_BROWSERS_PATH → playwright —— 全部位于 escapeRoot 之下，而 escapeRoot 从 $DSH_HOME 所在的盘派生（path.parse(dshHome).root），所以 DSH_HOME=E:\dsh\.dsh 时逃逸根是 E:\dsh_escape_cache。没有任何地方硬编码 E:。
两个刻意保持的性质：
process.env；不写注册表，也不写用户级/系统级环境块。restore() 精确还原。 原先不存在的变量在还原时会被删除，而不是设成字符串 "undefined"。旧值是被捕获下来的，不是硬编码的。赋值前会先过 SCRUB_PATTERN（/KEY|PASSWORD|SECRET|TOKEN/i），所以当用户把 MY_API_KEY 加进 envMap 时，它会带着原因被跳过，而不是悄悄被挪走。| 级别 | 条件 | 默认 |
|---|---|---|
🟢 SAFE_TO_DELETE | 未加锁并且（在 Temp 目录下或后缀为 .tmp/.log/.pyc/.bak或已知的一次性解压缓存） | 勾选 |
🟡 CAUTION_CACHE | 未加锁，且属于 AppData 工具链缓存 / 模型权重 / 浏览器内核 / 预编译 pkg | 不勾选 |
🔴 LOCKED_CRITICAL | 已加锁（WinError 32 / PermissionError）或名字长得像持久化文件（.lock、.sqlite、.db、auth、config、token） | 锁定，不可选 |
各条件之间是「与」的关系。锁检测探测的是文件能否被真正删除（fs.renameSync(path, path) → EBUSY/EPERM 表示已锁；ENOENT 表示未锁）。自我重命名需要的权限恰好就是删除权限，也就是真正要紧的那个操作。openSync(path,'r+') 是 Phase 1 的探测方式，实测证明它是错的：一个进程可以以读写共享打开文件但不给删除共享，于是 r+ 在无法删除的文件上也会成功（见 CONTRACTS.md §8.1）。
对 🔴 文件，谁占着它随后通过 Windows 重启管理器（lib/lock-owner.js）带外解析，得到真实的持有者 PID 与进程名；显示的正是这个名字。这一步是异步且带缓存的，因为同步的 classify() 不可能为一次约 140 ms 的 PowerShell 往返而阻塞。见下面限制第 3 条。
这些属性使自动删除站得住脚，每一条都有测试背书：
C:\Windows、C:\Program Files*、桌面、文档。clean() 会施加自己的否决，独立于 classify() 的返回，所以分类逻辑的 bug 无法扩大删除集。已演示：C:\Windows\Temp 下被分类为 SAFE_TO_DELETE 的文件，仍会被 clean() 以 protected path (PRD 6.2 hardcoded blacklist) — refused 拒绝。clean() 从不抛异常 —— 文件消失、文件被锁、空记录集，或运行中间出现 PermissionError，都会变成一条报告项；整轮继续（PRD 6.3）。Microsoft.VisualBasic.FileIO.FileSystem.DeleteFile(..., RecycleOption.SendToRecycleBin) 完成，每次调用批处理 ≤ 50 个路径。--force / useRecycleBin: false 才走物理删除。fs.watch({recursive:true}) 仅允许在 %LOCALAPPDATA%\Temp 之下使用。监听器会拒绝在盘根、%USERPROFILE%、C:\Users、C:\Windows*、C:\Program Files*、C:\ProgramData 上递归，并把拒绝记录在 stats().recursiveForcedOff 里。每个字段都是可选的，都有默认值。写在 bundle 行的 config 里：
- insert:
- id: dsh-c-cleaner
name: 'dsh-c-cleaner'
config:
debounceMs: 3000
useRecycleBin: true
| 键 | 默认值 | 含义 |
|---|---|---|

dshHome | $DSH_HOME | 逃逸根所在的盘由它派生 |
escapeRoot | <dshHome 所在盘>:\dsh_escape_cache | 劫持目标目录 |
stateDir | $DSH_HOME/plugins/c_cleaner | 状态目录 |
dbPath | <stateDir>/state.db | SQLite 文件 |
envMap | 见上 | 变量 → 子目录 |
watchDirs | %LOCALAPPDATA%\Temp（递归）、AppData Local + Roaming（深度 1） | 监听根 |
protectRoots | C:\Windows、C:\Program Files*、桌面、文档 | 永不删除 |

resolveLockOwner | true | 通过 Windows 重启管理器解析 🔴 文件的持有者 PID（PRD 3.3） |
noiseGate | 'enforce' | PRD §3.2 准入：enforce 丢弃未准入文件，audit 只计数但照旧记录，off 是 Phase 1 的直通 |
admitCriticalNames | true | §3.3 的安全阀：名字像凭证的文件永不被噪声过滤掉 |
handleIndex | false |
配置由手写的 Standard Schema（lib/config-schema.js）校验。Cordis 只要求 { '~standard': { version, vendor, validate } }（cordis/lib/index.js:956-962），直接实现它可以避免静态 import schemastery —— 后者要从 $DSH_PROFILE_DIR/node_modules 解析，一个解析失败的插件会整体加载失败，对一个可选的便利功能来说代价太高。

逐条写明，因为每一条都界定了本插件能承诺的范围：
除非打开句柄索引，否则 ProcessTree.ownerOf() 返回 null。 Node 在 Windows 上没有廉价的句柄→PID 映射，所以 PRD §3.2 规则 #1 由 lib/handle-index.js 承担 —— 一个可选的 psutil 驱动索引。它默认关闭，因为对一个 11 进程的树做一次句柄扫描实测要 约 2.0 s CPU（psutil 的 open_files() 对每个进程都要重新遍历系统句柄表），按 60 s 间隔已经是一个核心的 ≈3.4 % —— 超过 PRD 自己规定的 ≤2 % 边际 CPU 预算（PRD §6.1）。它从不编造 PID、每次扫描都缓存，并在超预算时自动关闭。默认 handleIndex: false 的实际后果是：是规则 #2（会话窗口 + AI 工具链签名）在填充候选集，外加下面的 §3.3 凭证闸。
噪声闸门带有刻意的 PRD §3.3 安全阀。 PRD §3.2 说只记录可归因于 dsh 或命中 AI 签名的文件 —— 但 PRD §3.3 要求 %TEMP% 里名字像凭证的文件必须以 🔴 LOCKED_CRITICAL 连同持有者一起出现。credentials.json 不匹配任何 AI 工具链签名，所以严格的签名闸门会把 §3.3 恰恰要求展示的东西悄悄过滤掉。因此 admitCriticalNames（默认 true）总是放行匹配 \.lock$|\.sqlite3?$|\.db$|auth|config|token|credential 的文件名。实机在同一目录同一秒验证：Win11SDK_*.msi → 被过滤；pip-*.log → 🟢 被跟踪；credentials.json → 🔴 被跟踪。设 noiseGate: audit 可只计数不丢弃，off 走旧直通。
谁占着被锁文件，走的是另一条路：Windows 重启管理器（lib/lock-owner.js，PRD §3.3）。classify() 是同步的，不可能为一次约 140 ms 的 PowerShell 往返而等待，所以 locked_by_pid 是在记录持久化之后回填的。因为 PRD §5 的 DDL 是固定的、没有持有者名字段，持有者进程名搭在 source_process 列上，且仅在尚无更好的值占据该列时。批量（每 250 ms 窗口一次 spawn）、带缓存（命中 30 s，未命中 5 s）、且只对真正被锁的记录触发 —— 罕见事件 —— 所以 PRD §6.1 的预算在结构上不受影响。设 resolveLockOwner: false 可关闭。实际后果：未加锁文件的 source_process 保持 null；只有 🔴 记录会获得持有者名字。
归属是尽力而为的，所以 dsh 会话期间有外部进程往 %TEMP% 写，可能被错误归属。%TEMP% 是共享目录；AI 签名过滤缩小了这个残差但没有消除它。正因如此，默认动作才是只把 🟢 项送入回收站。
诚实地说，残差很大。 规则 #2 是名字形状启发式，而 PRD 自己给出的示意签名列表（tmp*、*.log、*.tmp、*.pyc……）在 Windows 上很弱 —— 这些形状是操作系统和其他厂商不断产出的东西。按「该模式是否指向某个 AI 工具链」给被跟踪集合分桶（test/_lead-p2-noise-composition.mjs）：
| 桶 | 记录数 | 占比 |
|---|---|---|
A —— 工具链专属（pip-*、torch*、hf-*、node-*、*-cache） | 431 | 24.2 % |
| B —— 仅通用扩展名（、……） |

通过 plugin_manager { action: "install_bundle", target: "F:\\work\\dsh-c-cleaner" } 安装
→ {"changed":true,"application":"applied","warnings":[]}。
0.5.0 的清单修正之后，又通过 dsh plugin CLI 重装了一遍，一个临时 profile 和本机正在跑的 tauri profile 都装过：
$ node <DSH_BIN> plugin --profile <p> add F:/work/dsh-c-cleaner
dependencies:
+ dsh-c-cleaner link:F:/work/dsh-c-cleaner
Done in 347ms using pnpm v11.7.0
# 之后的 profile package.json：
# "dependencies": { "dsh-c-cleaner": "link:F:/work/dsh-c-cleaner" }
# "dsh.profile.bundles": ["dsh-c-cleaner"] <-- 由 reconcile() 注册
dsh --profile tauri --dump-config 随后把 overlay 组合为 # == dsh-c-cleaner / id: dsh-c-cleaner / name: dsh-c-cleaner，且 evaluatePluginCompatibility(manifest) 对运行时 0.2.1-rc.2 报告无问题。
（a）劫持确实到达真实子进程。 安装后的一次普通 harness bash 调用：
$ node -e "console.log(process.env.TEMP, '|', process.env.PIP_CACHE_DIR)"
E:\dsh_escape_cache\temp | E:\dsh_escape_cache\pip
$ cmd //c "echo TEMP=%TEMP%"
TEMP=E:\dsh_escape_cache\temp
Git Bash 对 $TEMP 打印 /tmp，看起来像失败但不是：MSYS 把 /tmp 别名到 $TEMP，cd /tmp && pwd -W 报告的是 E:/dsh_escape_cache/temp。原生 cmd 和原生 node 运行时都确认了被重定向的值。E:\dsh_escape_cache\ 现在包含 temp/ pip/ uv/ huggingface/ torch/ npm/ playwright/。
（b）监听器把真实的 C 盘写入记录进 SQLite。 往真实的 C 盘 %TEMP% 写一个文件（C:\Users\kiuhg\AppData\Local\Temp\lead-live-proof-1837.tmp），等过防抖窗口后，在活的 state.db 里得到：
{"file_path":"C:\\Users\\kiuhg\\AppData\\Local\\Temp\\lead-live-proof-1837.tmp",
"category":"SAFE_TO_DELETE","file_size":10,"is_locked":0}
（c）schema 就是 PRD §5 的 schema，由运行中的插件在 E:\dsh\.dsh\plugins\c_cleaner\state.db 创建：CREATE TABLE tracked_files (...) 带全部九个 PRD 列，加上 idx_tracked_files_category 和 idx_tracked_files_checked。唯一的偏差是 CREATE TABLE IF NOT EXISTS，这是 migrate() 幂等所必需的。
（d）PRD §6.1 达标。 同一个 10 秒、约 92 个文件的写入负载跑两遍 —— 一遍不挂监听器，一遍挂上 —— 得到插件的边际开销：
baseline : 10028ms, cpu 63.0ms => 0.63%
watcher : 10025ms, cpu 156.0ms => 1.56%
PLUGIN MARGINAL CPU : 93.0ms over 10025ms = 0.93 % (PRD <= 2%) -> PASS
RSS delta (plugin) : 2.7 MB (PRD <= 30MB) -> PASS
朴素测法（整个进程，包含 harness 自己的 fs.writeFileSync 调用）读到 2.65%，看起来像失败；插件自己的份额是 0.93%。递归保护同样拒绝了在 C:\ 和 C:\Users\kiuhg 上的 recursive:true —— recursiveForcedOff: 2。
插件一旦安装就运行在 harness 进程里，所以它的劫持在任何测试开始之前就已经生效。一个断言 process.env.TEMP !== <环境原值> 的测试会因此伪失败。要在构造 hijacker 之前为 TEMP/TMP/TMPDIR 设一个哨兵值，才能独立于安装状态测试真正的性质。
与此相关，插件活着之后 os.tmpdir() 返回的是被劫持后的逃逸根。用 os.tmpdir() 创建测试夹具，等于写进 protectRoot，监听器会正确地拒绝产出 —— 于是这样的测试测的是保护，不是监听器。要被观察到的夹具必须建在真实的 C 盘 %TEMP% 下。
已安装的包是指向本工作目录的符号链接（$DSH_PROFILE_DIR/node_modules/dsh-c-cleaner -> F:/work/dsh-c-cleaner），所以改动会立刻反映在磁盘上 —— 但运行中的 harness 继续用着它已经 import 的那一代模块。这在本机实测过，不是假设：用一个真实的 FileShare.None 句柄占住文件（正向对照：openSync(p,'r+') 抛出 EBUSY），活的监听器把记录持久化成 LOCKED_CRITICAL、is_locked=1，却让 locked_by_pid/source_process 保持 null —— 也就是运行中的进程仍在执行改动前的 index.js，那一版还没接线 LockOwnerResolver。同一个文件在现有模块下会解析出持有者。
harness 自带的 HMR 模块根是空的（@deepseek-ai/dsh-base/cordis.patch.yml 里 @deepseek-ai/dsh-hmr 的 config.root: []）—— profile 配置会热重载，模块代码不会。所以：改完 lib/ 或 index.js 之后要重启 harness，改动才会在活进程里生效。首次全新安装仍可通过 HMR 直接激活，因为没有旧的代际需要替换。

A C-drive escape monitor and safe cleaner for DeepSeek Harness: it keeps AI-toolchain caches and temp files off the C: drive, and reclaims the part that has already escaped.
Implements 产品需求与技术规格文档 (PRD).md as a native Cordis host plugin (Node.js, zero runtime dependencies beyond Node built-ins), covering the PRD's Phase 1 + Phase 2 + Phase 3.

The C-drive escape cleaner panel embedded in the Harness sidebar
Captured live: the Harness sidebar on the left with "C 盘逃逸清理" selected, and the glass panel it opened on the right — stat cards, the three-tier table, selection and the clean actions all on one screen.
The PRD's premise is "$DSH_HOME already moved to E:, so only C-drive escape writes remain". This plugin handles that residue in four layers:
| Stage | PRD | Module | Status |
|---|---|---|---|
| Pre-emptive — environment hijack | §3.1 | lib/env-hijack.js | implemented, live-proof captured |
| Live watch — C-drive writes | §3.2 | lib/watcher.js, lib/process-tree.js | implemented |
| Three-tier classification | §3.3 | lib/classifier.js | implemented |
| Cleanup — safe deletion | §3.4 | lib/cleaner.js | implemented |
Directory migration — mklink /J junction | §3.4 | lib/symlink-migrate.js | implemented (Phase 3) |
CLI/TUI — the c-clean command | §4 | lib/commands.js + lib/web-api.js + client.js | status, now, ui, migrate, unmigrate all implemented |
| Persistence — SQLite state | §5 | lib/state-db.js | implemented (node:sqlite) |
Silent clean on session close — post_session_close | §7 | lib/session-hook.js | implemented (Phase 3, opt-in) |
Both Phase 3 deliverables are in:
mklink /J junction migration (PRD §3.4/§7) — move a stubborn directory off C: wholesale, then leave a directory junction at the original path so programs that hardcode it keep working while their bytes land on the target volume. Undo is supported.post_session_close silent clean (PRD §7) — a session-close hook that quietly sweeps 🟢 files. The host has no event by that name; the hook binds session/disposed (see Known limitations #8). It is off by default (sessionCloseClean: false).ui is delivered as a Harness sidebar panel rather than a terminal TUI, because a Cordis slash command cannot render an interactive component.
dsh plugin is the official entry point: it is a pnpm front end that runs inside the profile directory and, after a successful install, rewrites dsh.profile.bundles for every new dependency that declares dsh.bundle. This package declares one (./cordis.patch.yml), so it becomes a live profile layer automatically — never hand-edit the profile's package.json or cordis.patch.yml, and never create packages under $DSH_HOME.
dsh plugin --profile <profile> add <abs path to this directory>
# e.g. dsh plugin --profile tauri add F:/work/dsh-c-cleaner
A relative directory works too, interpreted from the current working directory:
cd F:/work && dsh plugin --profile <profile> add ./dsh-c-cleaner
Both forms install a link dependency, so later edits in the checkout are visible on disk.
dsh plugin --profile <profile> add dsh-c-cleaner
Published:
dsh-c-cleaner@0.5.0, see https://www.npmjs.com/package/dsh-c-cleaner. This installs a^0.5.0registry dependency that pnpm copies into the profile'snode_modules(not a symlink), so re-runaddto upgrade later.
dsh plugin --profile <profile> add github:wuyu1327083461/dsh-c-cleaner
dsh plugin --profile <profile> add file:<abs path to dsh-c-cleaner-0.5.0.tgz>
Use a Windows-style path (file:C:/...), not an MSYS path (file:/c/...) — pnpm does not accept the latter.
plugin_manager toolThe same install, driven from an agent session rather than a shell:
plugin_manager { action: "install_bundle", target: "<abs path to this directory>" }
Replacing an already-installed copy of this package requires a harness restart to load a fresh JS module generation; a first-time install can activate via HMR.
files must containpnpm packs a git or tarball dependency according to the files array, so cordis.patch.yml must be listed there. If it is missing, the installed tree has no patch file and the install is rejected with:
dsh: installation rejected: ... failed to read overlay ... cordis.patch.yml: ENOENT
after which package.json, pnpm-lock.yaml and node_modules are rolled back. Path and link: installs bypass packing and are unaffected, which is why the omission can hide for a long time.

status output, first line is the PRD §4 contract format:
🟢 可清理: 342.0 MB (128个文件) | 🟡 缓存驻留: 1.2 GB | 🔴 正在占用: 3个文件
环境变量劫持: ✅ 已生效 (9/9 变量) → E:\dsh_escape_cache
ui)A slash command cannot render a component, so c-clean ui returns a pointer plus the live headline, and the actual UI is a Client-slot React panel in the Harness sidebar. Look for the C 盘逃逸清理 icon in the sidebar rail:
The panel is a full-page main-slot component fed by a fenced JSON API on the Host half:
| Endpoint | Method | Returns |
|---|---|---|
/c-cleaner/api/state | GET | {rows, hijack, escapeRoot, useRecycleBin, escapeWritable} |
/c-cleaner/api/refresh | POST | re-polls the process tree, then the same snapshot shape |
/c-cleaner/api/clean | POST | {report, rejected, rows} |
/c-cleaner/api/stale | GET | {count, bytes, scanned, kept} — how many tracked rows today's gate would reject |
/c-cleaner/api/purge | POST | forgets those rows, then {forgotten, bytes, remaining, rows} |
/c-cleaner/api/migrate | POST | {path} → moves it to E: and leaves a junction: {result, migrated, rows, migrations} |
/c-cleaner/api/unmigrate | POST | {path} → reverses a recorded migration: {result, migrated, rows, migrations} |
/state and /refresh deliberately return an identical snapshot shape. Returning a rows-only payload from /refresh made the header render "env hijack inactive" right after a refresh — a false alarm about the escape root on the panel's most load-bearing status line.
/stale + /purge)The PRD §3.2 noise gate (see Known limitations items 1–2 below) only applies to writes the watcher sees from now on. Rows written before it existed — measured live: 1079 of 2205 green rows, ~1.09 GB, mostly Windows SDK installers and Visual Studio DLLs that belong to other software — stayed in the table. They are not dangerous to delete: they are unlocked files in %TEMP%. But 全选可清理项 / 清理全部可清理 act on all green rows, so one click would have swept other software's installer payloads into the recycle bin, and they buried the dsh-authored rows the PRD actually asks this panel to show.
「清理过期条目」 removes exactly those rows from the view. It is bookkeeping only:
classifyName() the watcher uses, so there is one implementation of the admission rule, not two that can drift;SAFE_TO_DELETE rows are eligible — a 🔴 or 🟡 row is never forgotten, whatever its name;credentials.json survives), andGET /stale only counts, so the panel can show the number before the user commits.
/clean deletes files, and 127.0.0.1:3080 is reachable from any page on the machine. So every request must pass isTrustedApiRequest() (lib/web-api.js), which refuses a request unless its Host is loopback (or in trustedHosts), refuses sec-fetch-site: cross-site outright, and otherwise requires the Origin hostname to equal the Host hostname (with dsh-app://app, the desktop shell's own origin, allowed explicitly). A foreign Origin on an otherwise-loopback request is refused — proven live:
# live, against the running harness
curl -H 'Host: evil.example.com' http://127.0.0.1:3080/c-cleaner/api/state -> 403
curl -X POST .../c-cleaner/api/clean -d '{"paths":["C:\\Windows\\System32\\kernel32.dll"]}'
-> rejected, deletedCount 0
The second one is the load-bearing guard: the panel may only clean what the plugin already tracked. Every requested path is matched (case-insensitively) against the persisted rows, and each record handed to the cleaner is rebuilt from the persisted columns — a client that forges {"category":"SAFE_TO_DELETE"} for a 🔴 file cannot promote it. test/_lead-phase2-api.mjs asserts exactly that with a forged body.
The panel's own transport uses the page's directory base rather than an origin-rooted path (hostRouteUrl in client.js), because a leading-slash URL pins itself to the origin root and 404s behind a reverse-proxy directory. In the desktop shell the page is dsh-app://app/ and the shell's protocol handler forwards non-module paths to the Host same-origin.
/c-cleaner/ui)The React main-slot panel above is one of two renderings, and the second one is the one worth looking at. c-clean ui also opens the glass panel at http://127.0.0.1:3080/c-cleaner/ui/index.html — a self-contained document (2650 lines, zero external requests, no CDN, no framework) served by the plugin itself:
| Endpoint | Method | Returns |
|---|---|---|
/c-cleaner/ui/api/get_state | POST | the full snapshot: env groups, watch roots, tier rows |
/c-cleaner/ui/api/clean | POST | flat {ok, cleaned, skipped, freed_bytes} |
/c-cleaner/ui/api/migrate | POST | {ok, target, bytes_moved} — junction to E: |
/c-cleaner/ui/api/unmigrate | POST | reverses a recorded migration |
/c-cleaner/ui/api/poll_events | POST | {cursor, events} — the ⚡ 实时捕获 live channel |
It is served as-is instead of being rewritten as React components, because a 2500-line already-verified interface ported by hand is guaranteed visual drift. lib/panel-ui.js registers the route on a second prefix (/c-cleaner/ui, longest-prefix-wins over the existing /c-cleaner/api) and translates its flat dialect into this plugin's own {ok, value} envelope and category names — the document itself needed no edit, since its REST_BASE='api/' is a relative path the browser resolves against the document's own directory.
Two panel-specific behaviours are deliberate and load-bearing (lib/panel-snapshot.js):
findCandidates groups by path.dirname, which turns uv-cache/wheels/<1000 .whl> into 1000 rows that each refuse to migrate. The panel groups by the first directory under a watch root instead, so one 🟡 row == one migratable directory.realpath would print the E: path and destroy the one fact the row exists to convey — "already tunneled, but still occupying its C: slot".The live channel is a bounded ring buffer (LIVE_BUFFER_MAX = 500, index.js), not an unbounded log: the panel only ever asks for events newer than its last cursor, and a long-idle session must not grow it without limit. Rows are pushed to the buffer before any autoClean can remove the file, so the panel shows the capture even when the file is gone a moment later.
The PRD's premise is "$DSH_HOME already moved to E:, so only C-drive escape writes remain". Module 3.1 is what stops new ones.
There are two ways to feed a child process an environment variable in this harness, and only one of them can carry TEMP/PIP_CACHE_DIR:
ctx.shellEnv.register() contributes DSH_*-namespaced keys only (dsh-subprocess/lib/index.js:13 → const DSH_ENV_PREFIX = "DSH_"). It cannot carry TEMP.process.env works, because every harness child is spawned from a live read of the parent environment: dsh-subprocess/lib/index.js:50-56 scrubbedParentEnv() builds the child env from Object.entries(process.env), filtering only names matching /KEY|PASSWORD|SECRET|TOKEN/i and names starting with DSH_.So the plugin mutates process.env and nothing else. Verified against the real installed scrubbedParentEnv, with negative controls:
=== scrubbedParentEnv() AFTER hijack (what every harness child inherits) ===
PASS TEMP = E:\dsh_escape_cache\temp
PASS PIP_CACHE_DIR = E:\dsh_escape_cache\pip_cache_dir
... 9/9 hijacked variables survive the harness env scrub
--- negative control (proves the scrub is live) ---
MY_FAKE_API_KEY present : false (expect false — matches KEY)
DSH_SHOULD_BE_STRIPPED present: false (expect false — DSH_ prefix)
--- end-to-end: real child process ---
child cmd.exe saw TEMP = E:\dsh_escape_cache\temp
Reproduce with node test/_env-propagation.mjs.
Variables redirected (lib/config.js → DEFAULT_ENV_MAP): TEMP, TMP, TMPDIR → temp; PIP_CACHE_DIR → pip; UV_CACHE_DIR → uv; HF_HOME → huggingface; TORCH_HOME → torch; NPM_CONFIG_CACHE → npm; PLAYWRIGHT_BROWSERS_PATH → playwright — all under escapeRoot, which is derived from the drive of $DSH_HOME (path.parse(dshHome).root), so with DSH_HOME=E:\dsh\.dsh the escape root is E:\dsh_escape_cache. Nothing is hardcoded to E:.
Two deliberate properties:
process.env is mutated; nothing is written to the registry or to a user/system-wide environment block.restore() puts back exactly what was there. A variable that did not previously exist is deleted on restore, not set to the string "undefined". The prior value is captured, never hardcoded. SCRUB_PATTERN (/KEY|PASSWORD|SECRET|TOKEN/i) is checked before assigning, so a user who adds e.g. MY_API_KEY to envMap gets it skipped with a reason instead of a credential silently relocated.| Tier | Condition | Default |
|---|---|---|
🟢 SAFE_TO_DELETE | not locked and (in a Temp dir or suffix .tmp/.log/.pyc/.bak or known one-time unzip cache) | checked |
🟡 CAUTION_CACHE | not locked and AppData toolchain cache / model weights / browser kernel / precompiled pkg | unchecked |
🔴 LOCKED_CRITICAL | locked (WinError 32 / PermissionError) or a persistence-shaped name (.lock, .sqlite, .db, auth, config, token) | locked, non-selectable |
The conditions are AND-ed. Lock detection probes whether the file can actually be deleted (fs.renameSync(path, path) → EBUSY/EPERM means locked; ENOENT means not locked). A self-rename needs exactly the delete permission, which is the operation that matters. openSync(path,'r+') was the Phase 1 probe and measurement proved it wrong: a process can hold a file open with read+write sharing but WITHOUT delete sharing, so r+ succeeds on files that cannot be deleted (see CONTRACTS.md §8.1).
For a 🔴 file, who holds it is then resolved out-of-band through the Windows Restart Manager (lib/lock-owner.js), which yields a real holder PID and process name; that name is what gets displayed alongside the PID. This is asynchronous and cached, because a synchronous classify() cannot block on a ~140 ms PowerShell round trip. See limitation 3 below.
These are the properties that make automatic deletion defensible, and each is backed by a test:
C:\Windows, C:\Program Files*, Desktop, Documents. clean() applies its own veto, independent of what classify() returned, so a classification bug cannot widen the delete set. Demonstrated: a file under C:\Windows\Temp classified SAFE_TO_DELETE is still refused by clean() with reason protected path (PRD 6.2 hardcoded blacklist) — refused.clean() never throws — a vanished file, a locked file, an empty record set, or a PermissionError mid-run all resolve to a report entry; the run continues (PRD 6.3).Microsoft.VisualBasic.FileIO.FileSystem.DeleteFile(..., RecycleOption.SendToRecycleBin), batched ≤50 paths per invocation. --force / useRecycleBin: false opts into physical removal.fs.watch({recursive:true}) is permitted only under %LOCALAPPDATA%\Temp. The watcher refuses recursion on drive roots, %USERPROFILE%, C:\Users, C:\Windows*, C:\Program Files*, C:\ProgramData, and reports the refusal in stats().recursiveForcedOff.Every field is optional; all have defaults. Set them in the bundle row's config:
- insert:
- id: dsh-c-cleaner
name: 'dsh-c-cleaner'
config:
debounceMs: 3000
useRecycleBin: true
| Key | Default | Meaning |
|---|---|---|
enabled | true | master switch |
dshHome | $DSH_HOME | escape root drive is derived from this |
escapeRoot | <dshHome drive>:\dsh_escape_cache | hijack destination |
stateDir | $DSH_HOME/plugins/c_cleaner | state directory |
dbPath | <stateDir>/state.db | SQLite file |
envMap | see above | variable → subdirectory |
watchDirs | %LOCALAPPDATA%\Temp (recursive), AppData Local + Roaming (depth 1) | monitored roots |
protectRoots | C:\Windows, C:\Program Files*, Desktop, Documents | never deleted |
excludeNames | [".dsh"] | path segments excluded (.dsh itself is never monitored) |
aiSignatureGlobs | AI toolchain name patterns | session-window attribution |
debounceMs | 3000 | coalesce streaming writes |
pollIntervalMs | 5000 | process-tree poll |
sessionWindowMs | 1800000 | session window |
useRecycleBin | true | recycle bin vs physical delete |
maxBatch | 50 | paths per recycle-bin invocation |
resolveLockOwner | true | resolve a 🔴 file's holder PID via the Windows Restart Manager (PRD 3.3) |
noiseGate | 'enforce' | PRD §3.2 admission: enforce drops non-admitted files, audit counts but still records, is the Phase 1 passthrough |
Config is validated by a hand-rolled Standard Schema (lib/config-schema.js). Cordis only requires { '~standard': { version, vendor, validate } } (cordis/lib/index.js:956-962), and implementing it directly avoids statically importing schemastery, which resolves from $DSH_PROFILE_DIR/node_modules — a plugin that fails that resolution fails to load entirely, which is too high a price for an optional convenience.

Stated plainly, because each one bounds what this plugin can promise:
ProcessTree.ownerOf() returns null unless the handle index is enabled. Node exposes no cheap handle→PID mapping on Windows, so PRD §3.2 rule #1 is served by lib/handle-index.js, an opt-in psutil-backed index. It is off by default because a handle sweep over an 11-member tree measures ~2.0 s of CPU (psutil's open_files() re-walks the system handle table per process), which on a 60 s interval is already ≈3.4 % of one core — over the PRD's own ≤2 % marginal-CPU budget (PRD §6.1). It never fabricates a PID, caches each sweep, and auto-disables if sweeps run over budget. Practical consequence with the default handleIndex: false: rule #2 (session window + AI-toolchain signature) is what populates candidates, plus the §3.3 credential valve below.
The noise gate adds a deliberate PRD §3.3 safety valve. PRD §3.2 says to record only dsh-attributable or AI-signature files — but PRD §3.3 requires a credential-shaped file in %TEMP% to surface as 🔴 LOCKED_CRITICAL with its holder. A credentials.json matches no AI-toolchain signature, so a strict signature gate would silently noise-filter away exactly what §3.3 orders us to show. admitCriticalNames (default true) therefore always admits a basename matching \.lock$|\.sqlite3?$|\.db$|auth|config|token|credential. Verified live in the same directory and second: Win11SDK_*.msi → filtered; pip-*.log → 🟢 tracked; credentials.json → 🔴 tracked. Set noiseGate: audit to count without dropping, or off for the legacy passthrough.
Who holds a locked file is resolved by a different route: the Windows Restart Manager (lib/lock-owner.js, PRD §3.3). classify() is synchronous and cannot wait ~140 ms for a PowerShell round trip, so locked_by_pid is filled in after the row is persisted and patched back in. Because PRD §5's DDL is fixed and has no holder-name column, the holding process name rides in source_process, and only when nothing better already claimed that column. Batched (one spawn per 250 ms window), cached (30 s for a hit, 5 s for a miss), and reached only for rows that are genuinely locked — a rare event — so the PRD §6.1 budget is untouched by construction. Set resolveLockOwner: false to disable. Practical consequence: source_process for a non-locked file stays null; only 🔴 rows acquire a holder name.

$ node <DSH_BIN> plugin --profile <p> add F:/work/dsh-c-cleaner
dependencies:
+ dsh-c-cleaner link:F:/work/dsh-c-cleaner
Done in 347ms using pnpm v11.7.0
# profile package.json afterwards:
# "dependencies": { "dsh-c-cleaner": "link:F:/work/dsh-c-cleaner" }
# "dsh.profile.bundles": ["dsh-c-cleaner"] <-- registered by reconcile()
dsh --profile tauri --dump-config then composes the overlay as # == dsh-c-cleaner / id: dsh-c-cleaner / name: dsh-c-cleaner, and evaluatePluginCompatibility(manifest) reports no issue against runtime 0.2.1-rc.2.
(a) The hijack reaches real children. A plain harness bash call after installation:
$ node -e "console.log(process.env.TEMP, '|', process.env.PIP_CACHE_DIR)"
E:\dsh_escape_cache\temp | E:\dsh_escape_cache\pip
$ cmd //c "echo TEMP=%TEMP%"
TEMP=E:\dsh_escape_cache\temp
Git Bash prints /tmp for $TEMP, which looks like a failure but is not: MSYS aliases /tmp to $TEMP, and cd /tmp && pwd -W reports E:/dsh_escape_cache/temp. The native cmd and the native node runtime both confirm the redirected value. E:\dsh_escape_cache\ now contains temp/ pip/ uv/ huggingface/ torch/ npm/ playwright/.
(b) The watcher records real C: writes into SQLite. Writing one file into the real C-drive %TEMP% (C:\Users\kiuhg\AppData\Local\Temp\lead-live-proof-1837.tmp) and waiting out the debounce produced, in the live state.db:
{"file_path":"C:\\Users\\kiuhg\\AppData\\Local\\Temp\\lead-live-proof-1837.tmp",
"category":"SAFE_TO_DELETE","file_size":10,"is_locked":0}
(c) The schema is the PRD §5 schema, created by the running plugin at E:\dsh\.dsh\plugins\c_cleaner\state.db: CREATE TABLE tracked_files (...) with all nine PRD columns, plus idx_tracked_files_category and idx_tracked_files_checked. The only deviation is CREATE TABLE IF NOT EXISTS, required for migrate() idempotency.
(d) PRD §6.1 is met. Running the identical 10-second, ~92-file churn workload twice — once with no watcher, once with the watcher attached — gives the plugin's marginal cost:
baseline : 10028ms, cpu 63.0ms => 0.63%
watcher : 10025ms, cpu 156.0ms => 1.56%
PLUGIN MARGINAL CPU : 93.0ms over 10025ms = 0.93 % (PRD <= 2%) -> PASS
RSS delta (plugin) : 2.7 MB (PRD <= 30MB) -> PASS
The naive measurement (whole process, including the harness's own fs.writeFileSync calls) reads 2.65% and would look like a failure; the plugin's own share is 0.93%. The recursion guard also refuses recursive:true on C:\ and C:\Users\kiuhg — recursiveForcedOff: 2.
Once the plugin is installed it is running in the harness process, so its hijack is already applied before any test starts. A test that asserts process.env.TEMP !== <ambient prior> will therefore fail spuriously. Set a sentinel value for TEMP/TMP/TMPDIR before constructing the hijacker to test the real property independently of installation state.
Relatedly, os.tmpdir() returns the hijacked escape root once the plugin is live. A test that creates its fixture directory with os.tmpdir() is writing into a protectRoot, where the watcher correctly refuses to emit — so such a test measures the protection, not the watcher. Fixtures that are meant to be observed must be created under the real C: %TEMP%.
The installed package is a symlink to this working directory ($DSH_PROFILE_DIR/node_modules/dsh-c-cleaner -> F:/work/dsh-c-cleaner), so an edit is immediately visible on disk — but the running harness keeps the module generation it already imported. Verified on this host, not assumed: with a file held under a real FileShare.None handle (positive control: openSync(p,'r+') threw EBUSY), the live watcher persisted the row as LOCKED_CRITICAL with is_locked=1 and yet left locked_by_pid/source_process null — i.e. the running process was still executing the pre-change index.js, which did not yet wire LockOwnerResolver. The same file against the current modules resolves the holder.
The harness ships HMR with module roots empty (@deepseek-ai/dsh-hmr, config.root: [] in @deepseek-ai/dsh-base/cordis.patch.yml) — profile configuration hot-reloads, module code does not. So: restart the harness after editing lib/ or index.js for the change to take effect in the live process. A fresh first-time install can still activate via HMR because there is no stale generation to replace.

| D —— 无任何签名（闸门之前的遗留） | 32 | 1.8 % |
桶 B 的真实样本是其他软件的文件：BITS 的 BIT450E.tmp（Edge）、dd_BackgroundDownload_*.log、Adobe 的 dunamis-*.log、Visual Studio 的 tmp.edb。所以闸门能可靠地剔除大二进制形状（.msi、.dll、.exe —— 真正占盘的东西），但并不会把 %TEMP% 的产出收窄到只剩 dsh 写的文件。要真正补上这个缺口，需要规则 #1（句柄反查，被 §6.1 的 CPU 预算推成了可选项 handleIndex），或把 aiSignatureGlobs 收窄到工具链专属模式 —— 例如去掉 tmp*/*.log —— 那是用召回换精度的一行配置改动。
保护路径做了规范化，但没有哪种规范化是完美的。 isProtectedPath() 现在会解析 \\?\/\\.\ 设备前缀、UNC 与管理共享拼写、重复分隔符、每个路径段末尾的点和空格、8.3 短名（C:\PROGRA~1）、联接点/重解析点，并做大小写不敏感比较 —— 而且删除时的检查会重新解析，而不是信任分类时的缓存。这关闭了对抗测试发现的四个真实 PRD §6.2 绕过（见 test/run.js 的 A1/A6/A9/A10 探针）。但它仍然是一份「已知良好规范化形式」的黑名单，不是证明；还没人想到的文件系统写法不在覆盖范围内。
ui（PRD §4）以 Harness 面板交付，不是终端 TUI。 PRD 要求的是带热键的 Textual 风格终端面板；Cordis 的斜杠命令无法渲染交互式组件，所以面板是 Harness 侧边栏里的 Client-slot React 页面，c-clean ui 返回指向它的指针。PRD 的热键在面板内部得到保留（Space 切换勾选、Enter 清理所选、M 把所选目录迁移到 E 盘、R 刷新）。
迁移是移动，不是复制 —— 而且 PRD 的 mklink /J 不经 shell 完成。 PRD 点名 mklink /J；调用它意味着用 cmd.exe 拼接用户可控的带引号路径，这是经典的注入面。fs.symlinkSync(target, link, 'junction') 生成的是同一个 NTFS 联接点，无需 shell、无需管理员权限（由探针 P3 钉住）。跨卷 fs.renameSync 在 Windows 上不可能（实测 EXDEV），所以移动是 cpSync → 独立重新测量两侧目录树 → rmSync 源；账目不匹配就删掉半成品副本并保持源不动。日志行让被中断的迁移可恢复而不是丢数据。目录内有文件被打开时会在复制之前直接拒绝：inspectDirectory 探测每个文件并回答 FILES_IN_USE（并给出持有者），因为 rmSync 删不掉一个未给删除共享的文件，却会先把能删的删掉。关掉占用程序再重试。
Phase 3 的 post_session_close 是个名字，不是一个事件。 @deepseek-ai/* 里根本不存在这个标识符；真正的接缝是 Cordis 的 session/disposed（@deepseek-ai/dsh-session/lib/index.js:1813-1821，从第 1780 行的 detachEntered 到达），也是 dsh-session-telemetry、dsh-session-persistence-jsonl、dsh-session-projection-cache 订阅的同一个事件。钩子把 PRD 的名字保留在配置键里，好让需求可追溯。它是排在 clean() 前面的调度器，不是第二条删除路径：§6.2 / 目录 / 重解析点的每一项拒绝在删除时依然生效。
面板是进程启动时从清单里发现的。 @deepseek-ai/dsh-client-modules（lib/index.js:510,703,707,715,729 —— grep -n pkgMeta 找不到删除操作）只在那一刻读清单，所以一个在 harness 启动之后才获得 Client 半侧的插件，会一直缺席浏览器的启动图，直到重启。lib/client-graph.js 在进程内从磁盘清单重建那一条缓存项，并请注册表重新处理本插件自己的 loader 行，这就是面板无需重启即可出现的原因。它有特性探测，任何疑问下都空转；设 recoverClientGraph: false 可关闭。
插件只重定向它认识的变量。 一个不认这九个变量中的任何一个（或硬编码了 C 盘路径）的工具链仍然会逃逸；那部分残留正是模块 3.2–3.4 存在的理由。
由早于原始句柄注册表的模块代际武装的监听器，无法在进程内回收 —— 必须重启 harness。 在运行中的 harness 下编辑 lib/ 会热重载模块（HMR 层把这个目录当模块根监听），但 Cordis 并不总会在新代际启动前释放被取代的那一代。在本机用模块初始化/start() 标记实测：START live=1 … START live=2 而没有任何配对的 STOP，即两代监听器共存，且旧的那代继续按旧闸门规则写记录。现在有三道保护让 apply() 可重入安全：一个进程全局 Symbol.for('dsh-c-cleaner.active-generation') 槽位保存上一代的 disposer（模块级绑定不行，因为 HMR 会重新 import 模块体，每代都拿到新的空变量）；一个 Symbol.for('dsh-c-cleaner.live-watchers') 登记表，新代际会强制停掉其中的活 CWatcher；以及一个 Symbol.for('dsh-c-cleaner.raw-watchers') 登记表，记录原始 fs.FSWatcher 句柄，新代际直接关闭它们。真正治好泄漏的是原始登记表：_getActiveHandles() 返回 []，getActiveResourcesInfo() 也点不出本插件那套 watch 选项（{recursive:false, persistent:false} + unref()）对应的 FSEventWrap，所以没人登记过的句柄根本无法被发现 —— 这是用一个在完整句柄扫描之后仍能投递（delivered after scan-close: 2）的泄漏监听器测出来的。后果：在原始登记表存在之前泄漏过句柄的代际，三道保护都够不着它，所以它的记录会一直冒出来直到 harness 重启。损害是有界的：test/_lead-p2-gate-residue.mjs 把每条持久化记录按出厂闸门重新分类，报告0 条可删记录被闸门拒绝（全部残留在灰色 🔴/🟡 层，永远不会被删），所以这是一个准确性缺陷，而不是删除风险。
由早于认领槽位的模块代际注册的路由，必须按路径回收，因为 harness 的路由表只按路径删除。 实机实测：一次 HMR 重载之后，面板对每个动词都回答 500 {"code":"internal","message":"database is not open"}。原因：更早的一代仍然占着 /c-cleaner/api，于是新一代的 webServer.register 抛出 webserver: duplicate prefix route "/c-cleaner/api"，这个异常被吞掉了，所有请求继续打到死掉的那一代处理器上，而它捕获的 StateDB 早已被自己的 teardown 关闭。两道保护修好了它。(a) 路由的 disposer 停放在进程全局 Symbol.for('dsh-c-cleaner.web-api-route') 认领槽里，每次 dispose 都做归属校验 —— register 返回的是 () => table.delete(route.path)，它按路径而不是按身份删除，所以被取代的代际在 teardown 里无条件 dispose 会删掉新代际的路由、把 404 重新造出来。(b) registerWebApi 在注册之前直接从服务的 prefix 表（WebServer.prefixes，一个普通 Map）里回收自己的前缀，这才是治好「早于槽位的幽灵」的东西。只删除本插件自己的路径。探针：test/_lead-p2-coldboot-route.mjs 植入一个幽灵处理器，断言活着的代际替换它并回答 200（由 test/_lead-p2-coldboot-route-mutation.mjs 的 4 处变异证明）。

Attribution is best-effort, so a foreign process writing to %TEMP% during a dsh session can be mis-attributed. %TEMP% is a shared directory; the AI-signature filter narrows this but does not eliminate it. This is why the default action is recycle-bin deletion of 🟢 items only.
Measured honestly, the residual is large. Rule #2 is a name-shape heuristic, and the PRD's own illustrative signature list (tmp*, *.log, *.tmp, *.pyc, …) is weak on Windows, where those shapes are what the OS and other vendors emit constantly. Bucketing the tracked set by whether a pattern names an AI toolchain at all (test/_lead-p2-noise-composition.mjs):
| Bucket | Rows | Share |
|---|---|---|
A — toolchain-specific (pip-*, torch*, hf-*, node-*, *-cache) | 431 | 24.2 % |
B — generic extension only (*.tmp, *.log, …) | 778 | 43.7 % |
| C — PRD §3.3 credential valve | 539 | 30.3 % |
| D — no signature at all (pre-gate stragglers) | 32 | 1.8 % |
Real examples in bucket B are other software's files: BITS BIT450E.tmp (Edge), dd_BackgroundDownload_*.log, Adobe dunamis-*.log, Visual Studio tmp.edb. So the gate reliably removes large binary shapes (.msi, .dll, .exe — the stuff that actually fills the drive) but does not reduce %TEMP% churn to dsh-authored files only. Closing that gap properly needs rule #1 (handle reverse-lookup), which the §6.1 CPU budget pushes to opt-in (handleIndex), or an aiSignatureGlobs narrowed to toolchain-specific patterns — e.g. dropping tmp*/*.log — which trades recall for precision and is a one-line config change.
Protection is canonicalized, but no normalization is perfect. isProtectedPath() now resolves \\?\/\\.\ device prefixes, UNC and admin-share spellings, repeated separators, trailing dots/spaces per path segment, 8.3 short names (C:\PROGRA~1), junctions/reparse points, and a case-insensitive comparison — and the delete-time check re-resolves fresh rather than trusting the classify-time cache. This closed four real PRD §6.2 bypasses found by adversarial testing (see test/run.js probes A1/A6/A9/A10). It is still a denylist of known-good normalizations, not a proof; a filesystem form nobody has thought of yet is not covered.
ui (PRD §4) is delivered as a Harness panel, not a terminal TUI. The PRD asked for a Textual-style terminal panel with hotkeys; a Cordis slash command cannot render an interactive component, so the panel is a Client-slot React page in the Harness sidebar and c-clean ui returns a pointer to it. The PRD's hotkeys are honoured inside the panel (Space toggle, Enter clean selected, M migrate the selected folder to E:, R refresh).
Migration is a move, not a copy — and the PRD's mklink /J is done without a shell. The PRD names mklink /J; invoking it means spawning cmd.exe with a user-controlled quoted path, the classic injection surface. fs.symlinkSync(target, link, 'junction') produces the same NTFS junction with no shell and no admin rights (pinned by probe P3). Cross-volume fs.renameSync is impossible on Windows (measured EXDEV), so the move is cpSync → independent re-measure of both trees → rmSync of the source; an accounting mismatch deletes the partial copy and leaves the source untouched. A journal row makes an interrupted migration recoverable rather than lossy. A file held open inside the directory is refused up front: inspectDirectory probes every file and answers FILES_IN_USE (naming the holders) before anything is copied, because rmSync cannot remove a file held without delete sharing and would delete the ones it could reach first. Close the holding program and retry.
Phase 3's post_session_close is a name, not an event. No such identifier exists anywhere in @deepseek-ai/*; the real seam is Cordis session/disposed (@deepseek-ai/dsh-session/lib/index.js:1813-1821, reached from detachEntered at line 1780), the same event dsh-session-telemetry, dsh-session-persistence-jsonl and dsh-session-projection-cache subscribe to. The hook keeps the PRD name in its config key so the requirement stays traceable. It is a scheduler in front of clean(), not a second delete path: every §6.2 / directory / reparse refusal still applies at delete time.
The panel is discovered from the manifest at process start. @deepseek-ai/dsh-client-modules (lib/index.js:510,703,707,715,729 — grep -n pkgMeta finds no delete), so a plugin that gains a Client half after the harness started would stay out of the browser boot graph until a restart. lib/client-graph.js rebuilds that one cache entry in-process from the on-disk manifest and asks the registry to reprocess our own loader row, which is why the panel appears without a restart. It is feature-detected and no-ops on any doubt; set recoverClientGraph: false to disable.
The plugin only redirects variables it knows about. A toolchain that honors none of the nine variables (or hardcodes a C: path) still escapes; that residue is exactly what Modules 3.2–3.4 exist to catch.
A watcher armed by a module generation that predates the raw-handle registry cannot be reaped in-process — restart the harness. Editing lib/ under a live harness hot-reloads the module (the HMR layer watches this directory as a module root), but Cordis does not always dispose the superseded generation before the new one starts. Measured on this host with module-init/start() markers: START live=1 … START live=2 with zero paired STOP, i.e. two watcher generations coexisted, and the older one kept writing rows under the old gate rules. Three guards now make apply() re-entrant-safe: a process-global Symbol.for('dsh-c-cleaner.active-generation') slot holding the previous disposer (a module-scope binding cannot work, because HMR re-imports the module body and each generation gets a fresh empty variable); a Symbol.for('dsh-c-cleaner.live-watchers') registry of live CWatchers that a new generation force-stops; and a Symbol.for('dsh-c-cleaner.raw-watchers') registry of the raw fs.FSWatcher handles, which a new generation closes directly. The raw registry is the one that actually cures the leak: _getActiveHandles() returns [] and getActiveResourcesInfo() names no FSEventWrap for the plugin's own watch options ({recursive:false, persistent:false} + unref()), so a handle nobody registered is undiscoverable — measured with a leaked watcher that still delivered (delivered after scan-close: 2) after a full handle scan. Consequence: a generation that leaked a handle before the raw registry existed cannot be reached by any of the three guards, so its rows keep appearing until the harness restarts. Its damage is bounded: test/_lead-p2-gate-residue.mjs classifies every persisted row against the shipped gate and reports 0 deletable rows gate-rejected (all residue is in the greyed 🔴/🟡 tiers, which are never deleted), so this is an accuracy defect, never a deletion hazard.
A route registered by a module generation that predates the claim slot must be reclaimed by path, because the harness route table only deletes by path. Measured live: after an HMR reload the panel answered 500 {"code":"internal","message":"database is not open"} for every verb. Cause: an earlier generation still owned /c-cleaner/api, so the new generation's webServer.register threw webserver: duplicate prefix route "/c-cleaner/api", the throw was swallowed, and every request kept reaching the dead generation's handler whose captured StateDB had already been closed by its own teardown. Two guards fix it. (a) The route disposer is parked in a process-global Symbol.for('dsh-c-cleaner.web-api-route') claim slot, and every dispose is ownership-checked — register returns () => table.delete(route.path), which deletes by path, not identity, so an unconditional dispose in a superseded generation's teardown would delete the new generation's route and re-create the 404. (b) registerWebApi reclaims its own prefix directly from the service's prefix table (WebServer.prefixes, a plain Map) before registering, which is what actually cures a phantom that predates the slot. Only this plugin's own path is ever removed. Probe: test/_lead-p2-coldboot-route.mjs plants a phantom handler and asserts the live generation replaces it and answers 200 (mutation-proven by test/_lead-p2-coldboot-route-mutation.mjs, 4 mutations).
