-## 1.4.1 — 修「装完就用不了」的 cwd 变量崩溃
-
-### 症状
-
-装完插件、**还没点「应用」**，每一轮对话都失败：
-
-```
-unknown prompt variable "{{cwd}}" in section "deployment:persona-suffix";
-registered variables: provider, model
-```
-
-### 根因
-
-0.2.1 的 `dsh-agent-loop` 只注册两个提示词变量：
-
-```js
-ctx.systemPrompt.variable("provider", …)
-ctx.systemPrompt.variable("model",    …)
-```
-
-`cwd` 在 0.1.x 还有，0.2 拿掉了。而宿主的 `interpolate()` 遇到未注册变量不是留空，
-是**抛异常**：
-
-```js
-if (!Object.hasOwn(variables, name)) {
-  throw new Error(`unknown prompt variable "{{{name}}}" in ${kind} "${input.name}"; …`)
-}
-```
-
-旧版 `cordis.patch.yml` 给 `system-prompt` 配了：
-
-```yaml
-personaSuffix: Your working directory is {{cwd}}.
-```
-
-`deployment:persona-suffix` 是**每轮都参与渲染**的段，所以这个错在插件一装上就发生，
-与是否点过「应用」无关——这就是「基本上下载安装后都有」的原因。
-
-### 修法（三层，逐层收窄）
-
-| 层 | 文件 | 做法 |
-| --- | --- | --- |
-| **1. 配置** | `cordis.patch.yml` | `personaSuffix` 改为 `""`。persona 不再发任何变量；工作目录由宿主 runtime context 提供，persona 里重复一遍没有收益。 |
-| **2. 注册** | `lib/cwd-variable.js`（新） | 插件在 `systemPrompt` 全局层补一个 `cwd` provider，取值优先级 `agent.options.cwd` → `session.header.cwd` → `process.cwd()`。这样**用户自己 preset 里写的** `{{cwd}}` 也能解析。宿主已注册同名变量时抛 `already registered`，按成功处理。 |
-| **3. 兜底** | `lib/identity.js` | ① `overlayOfficialIdentity` 写出的 persona-suffix 改成纯文本；② 旧的 `Working directory: {{cwd}}.` 剥离后不再留变量；③ `sanitizeAssemblySections` 把任何残留的 `{{cwd}}` 降级成 `{ {cwd} }`——变量注册失败时也不会炸整轮。 |
-
-关键取舍：**不依赖「宿主会留空未注册变量」**。三层里任何一层单独生效都不会崩，
-三层齐全时 `{{cwd}}` 正常解析出真实路径。
-
-### 验证
-
-`npm run test:cwd`（`test/cwd-variable.mjs`，21 项）直接加载**宿主真实的**
-`dsh-system-prompt` 渲染器，逐条断言：
-
- 旧配置在 `provider/model` 两个变量下**确实抛错**，且报错文本与用户反馈一致（复现）
- 当前 `cordis.patch.yml` 的活动配置里没有 `{{cwd}}`
- `overlayOfficialIdentity` 的产物能渲染通过，输出里没有裸 `{{cwd}}`
- `registerCwdVariable` 注册后 `{{cwd}}` 解析出真实路径（含三条 fallback）
- 重复注册不算失败
- 转义后的文本能被宿主渲染（证明兜底不是装饰）
-
-找不到宿主模块时，依赖渲染器的断言会显式 `skip`，不会假装通过——上一版正是
-这种「看起来没问题」的验证方式漏掉了这个 bug。

 ## 1.4.0 — 借 IG5 的做法加固四处工程细节

 参考 [Minglink/dsh-infinite-gen-5](https://github.com/Minglink/dsh-infinite-gen-5) 的 `source/json_output.js`、`source/attachment_lease.js`、审批门与 CAS 修订号模式，挑了四处**与本插件能力相符**的改进。不搬它的逆向引擎、worker 协议、Ghidra / x64dbg 适配层——那些属于另一类插件。
@@ -289,6 +223,6 @@ DSH **0.2.1-rc.2**，82 条补丁：
 ## 七、已知限制 / Known limitations

 - **密封 `app.asar` 的桌面端**：补丁写在解开的 `resources/app` 里，必须走「应用」流程把 asar 挪走并重启才生效；只重启不换包，看到的仍是归档里的旧代码。
- **`{{cwd}}` 变量**：0.2.1 的 `dsh-agent-loop` 只注册 `provider` / `model`，裸写 `{{cwd}}` 会让宿主抛 `unknown prompt variable` 并打断整轮。**1.4.1 已修**：`lib/cwd-variable.js` 补注册该变量，`cordis.patch.yml` 不再发变量，`sanitizeAssemblySections` 兜底转义。详见上方 1.4.1 一节。
+- **`{{cwd}}` 变量**：0.2.1 的 `dsh-agent-loop` 不再注册该变量，提示词里写裸 `{{cwd}}` 会硬失败；需要工作目录时用宿主自带的 `personaSuffix` 或本地 `dsh-cwd-variable` 插件，`lib/identity.js#escapeDshInterpolation` 会把不安全的花括号转义。
 - **导航图标**：依赖「按 label 找到自己那一行」，设置外壳若改文案渲染方式，图标会回落成齿轮（功能不受影响）。
 - **未做**：插件市场发布、Web 端与桌面端一键同步、i18n 化全部文案（目前中英双语硬编码在 `client.js` 的 `zh` / `en` 两套字典里）。

-/**
- * `{{cwd}}` 变量兼容层。
- *
- * ## 为什么需要这个文件
- *
- * 0.2.1 的 `dsh-agent-loop` 只注册了两个提示词变量：
- *
- *     ctx.systemPrompt.variable("provider", …)
- *     ctx.systemPrompt.variable("model",    …)
- *
- * `cwd` 在 0.1.x 还有，0.2 拿掉了。而宿主的 `interpolate()` 遇到未注册变量是
- * **硬失败**，不是留空：
- *
- *     unknown prompt variable "{{cwd}}" in section "deployment:persona-suffix";
- *     registered variables: provider, model
- *
- * 这是每个新装用户都会撞上的错，因为本插件的 `cordis.patch.yml` 给
- * `system-prompt` 配了 `personaSuffix: Your working directory is {{cwd}}.`，
- * 而那条 section 每轮都会参与渲染。装完插件、还没点「应用」就已经炸了。
- *
- * ## 怎么修
- *
- * 两种做法，这里两个都做，因为它们解决不同层面：
- *
- * 1. **注册变量**（首选）。插件在 `systemPrompt` 的全局层补一个 `cwd` provider，
- *    这样任何引用 `{{cwd}}` 的段（包括我们自己的 personaSuffix，也包括用户自己
- *    在 preset 里写的）都能正常解析。宿主已注册同名变量时会抛 "already
- *    registered"，那时直接跳过——说明这份宿主本来就有，不需要我们补。
- *
- * 2. **改写配置**（兜底）。`cordis.patch.yml` 里的 `personaSuffix` 不再发裸
- *    `{{cwd}}`，改成不含变量的静态句。这样即使变量注册失败（比如宿主把
- *    `systemPrompt.variable` 藏起来），那一行也不会再把整轮打挂。
- *
- * 值从哪来：`context.agent.options.cwd` → `session.header.cwd` → `process.cwd()`。
- * 前两个是宿主的真实字段；最后一个只是「别让它是 undefined」的兜底——返回
- * `undefined` 会触发另一条硬失败（`has no value for this assembly`）。
