docs(readme): slim down and highlight improvements over the stock sidebar

- Rewrite the feature list as comparison bullets (editable editor,
  enhanced file tree, Changes / Background Tasks / Side Chat / bottom
  workbench — none of which the stock sidebar has)
- Split the full release history into CHANGELOG.md / CHANGELOG_EN.md;
  READMEs keep only v0.21.1 and link out
- Drop Star History; move the ecosystem section after Community
- Fix stale claims: v0.21.1 is the npm latest stable (not the alpha
  channel); drop the untruthful 'built-in browser' hero badge; pin
  '^0.21.1' in update / source-install notes
- Condense the install prose and the top IMPORTANT block

+# Changelog
+
+> 本文档收录 dsh-better-sidebar 的完整发布历史（最新版摘要见 [README](README.md)；同步发布于 [GitHub Releases](https://github.com/omdsh-dev/DSH-better-sidebar/releases)）。
+
+### v0.20.0（开发线，**从未发布**）
+
+> 🚫 **这一版没有发布到 npm**（npm 上 `latest` 仍是 v0.19.1）：它原本是 0.1.6-alpha.2 线的正式版，开发完成后被 0.21 线直接取代，所以下面这些变更实际随 **v0.21.1** 一起发布。原本的定位：仅支持 **DSH 0.1.6-alpha.2+**（peer 下限 `^0.1.6-alpha.2`，CI 钉 `@deepseek-ai/dsh@0.1.6-alpha.2`）。**这是一次破坏性变更版**：0.1.5-rc.* 用户请固定 `dsh-better-sidebar@0.19.1`。适配记录见 [docs/plans/2026-09-21-dsh-0.1.6-alpha.2-adaptation.md](docs/plans/2026-09-21-dsh-0.1.6-alpha.2-adaptation.md)。
+
+- 🖥️ **终端交给 DSH 内置**：DSH 0.1.6 自带右列终端（`ui-sidebar-terminal`），所以插件删掉了整套自研终端——`pty-manager` / `agent-pty` / `pty-deps` / 8 个 `terminal_*` 工具 / xterm 视图与字体链接 / 跨会话固定终端，以及 `node-pty` 依赖、它的 `allowBuilds` 放行与安装脚本的 `-Repair` 模式。**注意**：模型因而失去跨调用持久的终端（只剩一次性 `bash` / `pwsh`）；上游 `@deepseek-ai/dsh-tool-terminal` 未被内置 bundle 挂载，需要时请自行在 profile 里启用。
+- 🌐 **浏览器视图让给内置**：插件删掉 `BrowserView` / 沙箱状态条 / 嵌入性探测（含宿主 `browser.probe` 路由）与两个只配置自家 iframe 的设置项；**保留**聊天与界面的外链接管（按协议分流是宿主没有的能力），目标改为 DSH 内置的 `browser` tab 类型。
+- 🧩 **产物行交回宿主**：DSH 0.1.6 把 `conversation.chat.turnTail` 从 chain 改成 list（上游有意让多个插件**追加**而非互相替换），插件原来的接管只能与内置产物卡重复，因此整体删除；点击行为不变（内置走宿主 `openFile` → 本插件编辑器）。代价是失去轮尾那一个「在文件树中显示」入口（树内右键仍在）。
+- 🐛 **修复两个静默破坏**：`SidebarRightGuideEntry.id` 变成必填后，缺 id 会让**整个原生承载面静默空掉**（抛在 `ctx.inject` 回调里被吞）；`turnTail` 改 list 后原注册直接抛错、产物行失效。两处都已修好并加测试守护，同时补了注册失败的上报口。
+- 🎨 **空白面板卡片对齐内置卡风格**：`.paneCard` 改用 DSH 指南胶囊那套配方（0.5px l4 描边 / 24px 圆角 / layer-1 填充 / 56px 下限 / 14×20 内边距），并加测试守护其几何、令牌化配色，以及不复制上游那套**未定义**的 `--dsw-alias-bg-l1/-l2` 拼写。
+- 📐 **基线**：`@deepseek-ai/dsh-*` 全部钉 `0.1.6-alpha.2`，`dsh-code-runtime` 整包消失已移除，`diff` / `simple-icons` 作为 primitives 的新裸 import 提升进 devDependencies；`ui-primitives` 本版三处破坏（`IconSendOutline16` 下线、`TerminalBlockLabels.noExitCode` 新增、`ConnectionIndicator.reconnectLabel` 移除）同步适配。
+
+### v0.19.1
+
+> 📌 **正式版**（npm `latest`，无 prerelease 后缀）：钉版推进到 **DSH 0.1.5-rc.2**（npm `next`），**peer 下限仍是 `^0.1.5-rc.1`**——rc.2 的上游 delta 里没有任何触及本插件的面（零 `packages/api|host|session|agent` 变更，真实代码改动只有消息反馈弹窗、产物卡片 CSS 与 `CodeFileIcon` 的 SVG 数据拆分），因此 rc.1 用户无需升级 DSH 即可用本版。DSH 0.1.5-alpha.2 用户继续用 **v0.19.0-alpha.1**；0.1.2-rc.1 稳定线继续用 **v0.18.1**。
+
+- 🎯 **适配 DSH 0.1.5-rc.2**：devDependency 钉版、CI 挂载车道与 `SIDEBAR_SERVICE_VERSION` 同步到 rc.2；插件侧**零代码改动**（上游 delta 未触及本插件，逐文件核对见 [docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md](docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md)——300 个变更文件里绝大多数只是各包 `package.json` 的版本号单行）。
+- 🎨 **文件图标（#611）与内置 Tab 图标改为彩色**（#531 + #594 合并，实现按 rc.2 重做）：
+  - **文件/文件夹图标走 DSH 官方图形**：回退链末端是宿主 `ui-primitives` 的 `FileTypeIcon`（48 类官方全彩代码/配置图形 + markdown/图片/PDF/Office/视频/文件夹的类目色板），插件**不再自带扩展名表，也不再需要图标懒加载 chunk**——`#429` 那份 563 条彩色数据与 `lib/client-file-icons.js`（255 kB）连同 `fileIconTheme` 设置开关一并删除，彩色就是唯一形态（核心 bundle 因此只增 10 kB）。
+  - **新增对外 `registerFileIcon` API**（能力 `'fileIcons'`）：按扩展名（`exts`）、精确文件名（`names`）、目录名（`folderNames`）注册自己的图标，优先级降序、同级按注册序；**注意**：宿主分类器覆盖任意路径，所以注册 `exts: []` 的 catch-all 会接管所有未具体命中的行。
+  - **内置 tab 图标彩色**：文件 / 文件变动 / 任务管理 / 侧边对话 / 终端 / 浏览器 六个类型与 diff 视图的 glyph 换成彩色版本（颜色全部来自 `--dsw-alias-*` 令牌，皮肤照旧全覆盖）。
+  - **原生右侧栏的 tab 芯片也带图标**：宿主的 tab 定义没有 icon 字段，但 `sidebar.right.pane.tab.title` 槽就是芯片内容——插件在该槽渲染「图标 + 标题」（编辑器 tab 带路径时显示该文件的图标），glyph 为 `aria-hidden`，芯片可访问名不变。
+- 🛠 **CI 修复一：Windows lane 的真实超时**。`ci-windows` 在 2026-09-09/10 窗口内红了 8 次，其中 6 次是真起进程的用例撞上 vitest 默认 5000ms：`tests/agent-pty.spec.ts`（真起 PowerShell + ConPTY）与 `tests/install-powershell.spec.ts`（冷启 `powershell.exe` 实测 12.1s）现在各自声明 30s 预算，且 `vitest.config.ts` 的全局 `testTimeout` 从默认 5000ms 提到 **15s**（第一次真实 Windows 跑又在**第三个**文件上翻车：`tests/git.spec.ts:85` 耗时 9607ms——三个文件同一个根因，逐文件加超时是打地鼠）；`waitForTranscript` 的内层轮询预算从 5000ms 降到 15s，**内层预算必须小于外层**（原先是同一个 5000ms，结构性必然超时）。`ci-windows` 的 `Test` 改跑 `pnpm test:windows`（`--maxWorkers=2`），在 2 核 runner 上不再让真起进程的 spec 互相抢占。
+- 🛠 **CI 修复二：挂载车道的 npm 安装**。`plugin-mount` 的 `npm install -g @deepseek-ai/dsh@<ver>` 曾 4 次失败（2 次 `ETARGET`、2 次 `JavaScript heap out of memory` exit 134）：钉版自身的传递依赖是浮动 `^` 范围，上游**分阶段发布**预发布版时（rc.2 于 09-10 的 14:43–14:57 逐包上线）npm 会组出 rc.1/rc.2 混合 peer 图（3062 条 ERESOLVE）。现在钉一个**已完整发布**的 rc.2（修 ETARGET）并加 `NODE_OPTIONS=--max-old-space-size=4096`（修 OOM）。中途试过 `--legacy-peer-deps`，被真实 CI 否掉：它跳过的正是全局安装必须提供的 peer，`dsh-app-boot` 在 boot 时 require 的 `@deepseek-ai/cordis-plugin-group` 是 peer 而非 dependency，加了它 CLI 直接 `ERR_MODULE_NOT_FOUND`。
+
+### v0.19.0
+
+> 📌 **正式版**（npm `latest`，无 prerelease 后缀）：本版仅支持 **DSH 0.1.5-rc.1+**（peer 下限 `^0.1.5-rc.1`，CI 钉 `@deepseek-ai/dsh@0.1.5-rc.1`）。DSH 0.1.5-alpha.2 用户请继续用 **v0.19.0-alpha.1**（npm `alpha` 标签仍指向它）；0.1.2-rc.1 稳定线继续用 **v0.18.1**。
+
+**✨ 新功能**
+
+- 📝 **新建标签页列表恢复可选说明**（#613）：DSH 0.1.5-rc.1 让 `SidebarRightGuideEntry.description` 回归（可选），插件随之恢复 `TabDescriptor.description`，六个内置类型各写回一条说明（原生指南的 文件 / 文件变动 / 任务管理 / 侧边对话 / 终端 / 浏览器 六行都带上它），`guideDesc*` 词条回到 20 份词典。**宿主的原生指南只在列出的条目 ≤ 4 条时渲染说明**（更长的列表是整列丢弃，不是截断），而插件默认贡献 6 个 guide 条目——因此默认组合下说明不渲染，只有在插件设置页关掉足够多的 tab 类型、把 guide 压到 ≤ 4 条时才会出现。未声明说明的条目仍是「图标 + 标题」单行（插件不补通用兜底句）。
+
+**🐛 修复**
+
+- 无。rc.1 相对 alpha.2 的 delta 很小（373 个变更文件，绝大多数是上游各包版本号、原生右侧栏预览 UI 打磨与测试快照），除上述说明字段回归（并附带上游 `files` 类型改用自己的彩色文件夹图标作指南字形）外，没有需要插件适配的变更。
+
+**🧰 CI 与内部**
+
+- 基线推进到 **DSH 0.1.5-rc.1+**（#613）：peer 下限、devDependency 钉版、CI 挂载车道与 `dsh.plugin.json` 的 `engines.dsh` 同步（rc.1 在 npm 上同时是 `latest` 与 `next`）。
+- 明确未变、不必再核：全局主面板模型（`main` 槽 / `sidebar.panellist` / `ctx.layout` / 根级 `rightbar` + `rightbar.session`，插件仍不接入）、文件地址语法（`packages/util/workspace-path` 只动了版本号）、原生 tab 体宿主契约（`.paneBody` 仍是有确定高度的块级滚动容器）、core / agent / session / subagent 宿主 API 与 `ui-primitives` 导出面（仅 CodeBlock 渲染变化）。
+- `@deepseek-ai/dsh-client-ui-primitives@0.1.5-rc.1` 仍不声明 `dependencies` 而 bundle 仍裸 import `anser` / `shiki` / `@shikijs/langs/*` / `mdast-util-*` / `micromark-*` / `katex`——上一版提升进 devDependencies 的那组包因此保留，不得回退。
+- 真机验证（DSH 0.1.5-rc.1 + 插件 0.19.0）：门禁 `typecheck` / `lint` / `check:consumer-types` 全绿，单测 **124 files · 1296 passed · 9 skipped**，`pnpm peers check` 干净；挂载冒烟对真实 rc.1 **7 passed**（含 tab 体填充断言，以及新增的「指南 ≤4 条时说明才渲染」断言）；本地 3080 实测：guide 六行仍是「图标 + 标题」（6 > 4，说明按上游规则不渲染；上游把胶囊 `min-height` 从 48px 调到 56px），文件树点击 `AGENTS.md` 落到插件编辑器（CodeMirror 就绪），sidechat 输入框贴底（宿主盒 962px == 面板体 962px，composer 底边距 8px），底部工作台与中心列左右边完全重合，`pageerror` 0（控制台仅有第三方 `dsh-tauri-worktree` 的 `/api/dsh-worktree/attach` 500，与本次改动无关）。
+
+### v0.19.0-alpha.1
+
+> 🧪 **alpha 通道**（npm dist-tag `alpha`，安装 `dsh-better-sidebar@latest`）：本版仅支持 **DSH 0.1.5-alpha.2+**（peer 下限 `^0.1.5-alpha.2`，CI 钉 `@deepseek-ai/dsh@0.1.5-alpha.2`）。0.1.5-alpha.1 请继续用 **v0.19.0-alpha.0**；0.1.2-rc.1 稳定线用 **v0.18.1**（npm `latest`）。
+
+**✨ 新功能**
+
+- 🪟 **每个 tab 体都填满面板**（#609）：原生右侧栏的 tab 体宿主是「有确定高度的块级滚动容器」而非 flex 容器，此前插件各 tab 的根只写 `flex: 1`，在块容器里塌成内容高度——侧边对话的输入框因此贴不到面板底（转录一长就被推出可视区）。现在 native 适配层统一给每个 tab 体包一层 `height: 100%` 的列 flex 宿主，插件全部 tab（含第三方 `registerTab` 注册的 descriptor）恢复与底部工作台一致的填满语义。
+
+**🐛 修复**
+
+- 🧭 **跟随 DSH 0.1.5-alpha.2 的文件地址语法**：`fileAddressFor` 一律产出 session 作用域地址、绝对路径保留前导 `/`；`parseFileAddress` 改为前缀解析并忽略 `?`/`#` 后缀。
+- 🪟 **底部工作台的中心列定位跟随 alpha.2 全局面板改动**：`conversation` 槽改为根级 `main` keyed 槽下的 `main.conversation`，定位器改认新 key 并跳过 `display: contents` 槽宿主（alpha.1 的旧 key 仍兼容）。
+
+**🧰 CI 与内部**
+
+- 基线推进到 DSH 0.1.5-alpha.2（#609）：peer 下限、22 个 devDependency 钉版、CI 挂载车道与 `dsh.plugin.json` engines 同步；`pnpm peers check` 干净（按 §3-9 补提 `dsh-session-persistence` 传递 peer）。
+- **移除 `TabDescriptor.description`**：alpha.2 的原生指南条目不再渲染第二行（改为「图标+标题」胶囊），该字段与 6 个 `guideDesc*` 词条（20 份词典）一并下线；新建标签页的默认页改由注册表选（恰好 1 个指南条目则直接打开它）。
+
+### v0.19.0-alpha.0
+
+> 🧪 **alpha 通道**（npm dist-tag `alpha`，安装 `dsh-better-sidebar@latest`）：本版仅支持 **DSH 0.1.5-alpha.1+**（peer 下限 `^0.1.5-alpha.1`，CI 钉 `@deepseek-ai/dsh@0.1.5-alpha.1`）。0.1.2-rc.1 稳定线请继续用 **v0.18.1**（npm `latest`）。
+
+**✨ 新功能**
+
+- 🖥️ **接入 DSH 原生右侧栏**（#604）：右列改为 DSH 自己的右侧栏——插件的 7 个 tab 类型全部注册成原生 tab 类型 + 原生 tab 体；聊天里的文件打开统一走 `ctx.sidebarRight.openResource(dsh-resource://file/…)`；`editor` 类型以 `extension` 优先级认领文件资源（压过内置文本预览）并接管内置「文件」页 kind（注销即复位）；跨会话打开在目标会话未上屏时排队重放。
+- 🧩 **退役插件自绘右侧面板与自由窗口**（#605）：右列归 DSH 后，插件只保留底部工作台（单分栏树、随会话持久化），开合按钮注册进 DSH 会话头 utilities 槽；浮窗 API（`floats` / `floatTab` / `dockFloat` / `raiseFloat` / 右键「移动到自由窗口」）、`features` 里的 `'floatWindows'`，以及 `openByDefault` / `defaultWidthPercent` / `changesDiffFloat` 三个设置项一并删除（旧持久化文档里的 `floats` 字段被忽略，不影响加载）。
+- 🔗 **适配 DSH 0.1.5 宿主契约**（#603）：`assistant/chunk` 事件删除 → 实时增量改由 `agent/assistant-stream` 帧折叠（侧边对话转录的 `live` 字段）；`sessionPersistence.inspect` 删除 → 冷会话读取改走 `open(id,'read')`；会话头 `version` 用 `SESSION_FORMAT_VERSION`。
+
+**🐛 修复**
+
+- 侧边对话转录 / `jobs.output` 回放 / fork 继承等 8 处会话事件读取跟随 0.1.5 契约；自定义种子补齐 fork 标记对，避免继承父会话未领取的 inbox 输入。
+
+**🧰 CI 与内部**
+
+- 真机挂载冒烟门禁钉 0.1.5-alpha.1，e2e 增加「展开原生栏 → 经引导页逐个打开插件 tab 类型」的巡检；typecheck / lint / 单测 / 挂载车道全绿。
+
+### v0.19.0（未发布）
+
+- 🎨 **可选彩色图标主题**：设置页「文件 → 文件图标」可在**内置单色**与**彩色品牌图标**之间切换——彩色主题含 563 条规则（218 扩展名 + 197 精确文件名 + 148 目录名，如 `.tsx → React`、`package.json → npm`、`node_modules` 着色），数据在**懒加载 chunk**（`lib/client-file-icons.js`）里，只有选中时才下载，默认关闭时启动零开销。数据源自 [#429](https://github.com/omdsh-dev/DSH-better-sidebar/pull/429)（@fenter）。
+- 🎨 **文件图标多样化 + 对外图标注册 API（[file-icons.tsx](./src/client/file-icons.tsx)）**：文件树与编辑器文件 tab 不再是单一 `VscFile`——markdown / 图片媒体 / PDF / JSON / 40+ 代码扩展 / 配置 / 数据库 / lock / 压缩包各有专属 glyph（VSCodicons 单色 `currentColor`，遵循皮肤契约），未知扩展回退通用图标。`ctx.betterSidebar` 新增 `registerFileIcon`（`features` 含 `'fileIcons'`）：按扩展名 / 精确文件名（`names`）/ 目录名（`folderNames`）注册自定义图标（彩色 ReactNode 亦可，颜色责任在注册方），`exts: []` 为全局默认（只兜内置 glyph 没认领的扩展，不吞掉内置多样性），保留扩展名 `'folder'` / `'folder-open'` 可换目录行图标；`fileIcon` / `folderIcon` 为权威解析器（完整回退链 + 逐工厂崩溃隔离），注册/注销即时生效。接入示例见[外部插件指南 §7](./docs/external-plugin-guide.md)。
+
+### v0.18.1
+
+> 📌 **正式版**（npm `latest`）：DSH 基线不变（**0.1.2-rc.1+**，peer 下限 `^0.1.2-rc.1`）——本版是 v0.18.0 之后的增量发布：变更面板预览能力增强、文件树可写，以及五项修复。
+
+**✨ 新功能**
+
+- 📄 **变更面板操作预览增强**（#499）：`.md` 阅读模式（含 mermaid 渲染）、`.html` 与 `.pdf` 内嵌渲染预览；diff 语法高亮扩展到 mjs/cjs/mts/cts、CSS/SCSS/Less、HTML/XML/SVG/Vue、GraphQL、JSONC/JSON5；新增**密钥脱敏**层（预览默认开启，面板头部可切换）
+- 🗂️ **文件树重命名 / 删除**（#550）：行内重命名 + 确认式删除，右键菜单减重与子菜单视口钳制
+- 🧩 **插件目录名与 shell 预设文案词典化**（#535）：跟随宿主语言
+
+**🐛 修复**
+
+- 🔀 **git diff 折叠上下文真实展开**（#576，修复 #577）：折叠行此前显示「n 行…点击展开」却点不动（`-U3` 裁剪使 gap 段没有行文本）；现按需经 `git.show` 拉取两侧完整内容切片填充，带加载 / 失败降级三态与请求去重；顺带修复该路由的 `rev:path` 寻址（此前恒返空）
+- 💬 **侧边对话种子不再继承父会话未领取的 inbox 消息**（#562）：补 fork 标记对，消除「上下文很长时侧边对话先把之前的 User 消息发出去」的幽灵消息
+- 🖼️ **Markdown 分栏渲染器内的本地图片**（#569）：改写为可访问 URL，不再 404
+
+**🧰 CI 与内部**
+
+- ESLint flat config 接入 CI 与 Makefile（#536）、Makefile 命令面规范化（#526）、e2e 脚本加固（#527）、共享组件测试工具收敛样板（#524）
+- 重构：Sidebar.tsx 按关注点拆分（#542）、四处轮询习语收敛到 `use-polling`（#541）、删除 rc.7 宿主的 `__DSH_MODULES__` 回退路径（#540）、One Dark/Light 语法色板单源化（#534）、重复实现收敛与死代码清理（#525）
+
+### v0.18.0
+
+> 📌 **正式版**（npm `latest`）：本版仅支持 **DSH 0.1.2-rc.1+**（peer 下限 `^0.1.2-rc.1`）；不再支持 0.1.0-rc.8 ~ 0.1.1-rc.2——DSH stable 用户请固定安装 `dsh-better-sidebar@0.17.1`，停留在 0.1.2-alpha.x 的宿主继续用 `dsh-better-sidebar@latest`（v0.18.0-alpha.0）。
+
+**✨ 新功能**
+
+- 🌿 **「文件变动」统一 tab**（#475）：Git 视角（真 diff / 历史 / 暂存·提交·还原 / worktree·子仓库选择）与本轮文件视角（模型读/写/编辑实时追踪）双视角合一；统一 diff 渲染（改蓝配对 + 行内字符级高亮 + 语法着色 + 上下文折叠）、底部可拖拽预览面板、一键展开独立 diff tab
+- 💬 **侧边对话渲染升级**（#486）：主对话级 Blocks 结构、turn 用量尾标、断线重连横幅
+- ⚙️ **工作区路径围栏开关**（#458）：新增 `workspaceFence` 声明式设置键，工作区外路径 403 时错误面一键关闭并指引

+
+- 🔗 **适配 DSH 0.1.2-alpha.5（npm 已发布，`alpha` dist-tag）**：CI 挂载门禁钉版、`dsh.plugin.json` engines 下限与 `@deepseek-ai/*` peer / devDependencies 基线升至 0.1.2-alpha.5（真机挂载冒烟 14/14 验证）。`dsh-client-locale` 上游停在 0.1.2-alpha.3 未发新版，其 peer 下限 / devDep 保持并天然兼容 alpha.5 运行时（`pnpm peers check` 零失配，无需新增提升传递 peer）。代码适配了 alpha.4 的兼容性标记改动——`Session.events` 属性移除，迁移到按需读 API `snapshotEvents()`（sidechat 转录 live 读、fork 继承、`jobs.output` 回放、subagent 活跃度共 8 处），新建线程 meta 中宿主已删的 `seedLength` 一并移除；alpha.4 其余变化（双向 `send_message`、自定义模型发现复用 Profile 请求头、`SessionSeq`/`SessionLogOffset` 强类型）与 alpha.5（升级启动修复）经核实不触及本插件其余表面。

+- 🔗 **适配 DSH 0.1.2-alpha.2（npm 已发布，`alpha` dist-tag）**：CI 挂载门禁钉版与 `@deepseek-ai/*` devDependencies 基线升至 0.1.2-alpha.2（真机挂载冒烟 14/14 验证）。适配点：`dsh-settings` 移除运行时导出 `settingsNamespace`（命名空间改为编译期校验，宿主侧直接传常量）；`dsh-subagent` 描述符版本 2→3（由宿主包盖章，测试断言跟随 `SUBAGENT_DESCRIPTOR_VERSION` 常量）；`SessionEvent.ignorable` 恢复与 Remote 网关 `RemoteError` 封装经核实对本插件无破坏。
+- 🐛 **修复 DSH 0.1.2-alpha.1+ 上侧边对话转录空白**：转录轮询此前仍走 alpha.1 已移除的 `ctx.connection.api`（错误被静默吞掉，tab 永远渲染空转录），现改由插件自有 `sidechat.events` 路由供给（活线程读内存事件日志、冷线程读会话持久化，`afterSeq` 增量拉取，[sidechat-routes.ts](./src/sidechat-routes.ts)）。
+- 🧹 **删除对 0.1.1-rc.x 及更早的兼容层**：e2e 宿主 RPC 从点分/斜杠双方言收敛为斜杠单方言（token URL 必选，[host-protocol.ts](./tests/e2e/host-protocol.ts)）；`MarkdownText` labels 收敛为嵌套单形状（[markdown-labels.tsx](./src/client/markdown-labels.tsx)，不再双 prop 名）；peerDependencies / devDependencies / `dsh.client.inject` / chunk externals 白名单四处同步清除已消亡的 `@deepseek-ai/dsh-client-runtime`。
+
+### v0.17.1
+
+- 🔗 **DSH 0.1.2-alpha.1 适配（双版本兼容）**：DSH 0.1.2-alpha.1 的 Remote gateway、一次性 token 浏览器鉴权与 `MarkdownText` labels 契约变更已全量适配，插件在 0.1.0-rc.8 ~ 0.1.1-rc.2 与 0.1.2-alpha.1 上一致工作（后者经 GitHub tag 源码构建的真机挂载冒烟 14/14 验证；alpha.1 至今未发布 npm，CI 钉版已在 v0.18.0-alpha.0 升至 npm 发布的 0.1.2-alpha.2）。要点：`MarkdownText` 四个渲染点统一改走双形状 labels helper（[markdown-labels.tsx](./src/client/markdown-labels.tsx)），修复 alpha.1 上 markdown/mermaid 预览的 `reading 'code'` 崩溃；e2e 冒烟双协议化（token URL 换 cookie、`/api` 斜杠端点 + 按参数名包装 args，[tests/e2e/host-protocol.ts](./tests/e2e/host-protocol.ts)）；移除已在 0.1.2-alpha.1 消亡的 `@deepseek-ai/dsh-client-runtime` peer

+### v0.16.0
+
+自 v0.15.2 以来的全部更改：
+
+**✨ 新功能**
+
+- 🪟 **自由窗口**（[#354](https://github.com/omdsh-dev/DSH-better-sidebar/pull/354)）：把标签栏的任意 tab（内置或插件注册）**拖到主会话区域**——会话列出现虚线提示浮层，松开即成为悬浮窗口（默认 390×780，手机竖屏比例，创建时按视口钳制后居中于松点）；窗口支持头部拖动移动、右下角 SE 缩放（≥320×200）、点击任意处置顶、头部右键「回到侧边栏 / 关闭」、X 走 `closeTab` 正常关闭生命周期（释放终端等）；拖到侧边栏 pane 上时该 pane 高亮、松开即**停靠**合并回该 pane；`floats` 随会话持久化（刷新原样恢复，宽容 sanitize + 几何钳入视口）；服务语义：`features` 新增 `'floatWindows'`——`openTab` 的 dedupe/id 聚焦命中浮动 tab = **置顶窗口**（不重复开、不展开面板），`closeTab` / `activateTab` 对浮窗正常关窗 / 置顶并照常触发回调，浮窗内 tab `visible` 恒 true，agent 终端 reconcile 覆盖浮窗；tab 内容复用常规渲染、插件 tab 与 pane 完全同契约；附带文件二级页面 8px 网格间距规整（[设计文档](docs/plans/2026-08-23-free-window-design.md)）
+- 📂 **模型主动打开（`sidebar_open` 工具）**（[#353](https://github.com/omdsh-dev/DSH-better-sidebar/pull/353)）：侧边栏新增全局设置 `agentOpenTools`（**默认关闭**），开启后向模型注入**一个**工具——模型可在调用方会话的侧边栏打开本地**文件**（editor tab，按 path 去重）、**文件夹**（全窗树窗口，以该目录为根，`meta.dir`）与 **HTTP(S) 网页**（browser tab，URL 预填）；关闭设置即注销工具并清空未投递队列，已打开 tab 保留；非激活会话的打开排队、下次可见时重放（`/sidebar/ws/agent-opens` 推送，同一 trust fence）；无新增公共 API、不改变 `BetterSidebarService`（[设计文档](docs/plans/2026-08-23-agent-open-tools-design.md)）
+- 📝 **Markdown README 级内嵌 HTML + 目录大纲（TOC）**（[#360](https://github.com/omdsh-dev/DSH-better-sidebar/pull/360)）：Markdown 预览现在真实渲染**块级内嵌 HTML**——徽章墙 `<div align=center>`、`<details>` 折叠块内嵌 markdown、表格单元格 `<br/>`/`<sub>`/`<img>`、`<video>`/`<picture>` 全部经 DOMPurify 白名单消毒（`<script>` 等活性内容剥除、`<a>` 强制 `_blank rel=noopener`），本地媒体 src 重写为会话媒体路由；≥3 标题出现浮动**目录大纲**按钮，点击平滑滚动并自动展开折叠 `<details>`，HTML 段内标题同样收录；渲染器仍是宿主 `MarkdownText`（shiki / KaTeX / GFM 保留），纯 markdown（零 HTML）文档走原路径零回归（[设计文档](docs/plans/2026-08-24-markdown-html-toc-design.md)）
+- 🌏 **第三语言覆盖（19 语言）**（[#339](https://github.com/omdsh-dev/DSH-better-sidebar/pull/339)）：接入可选 peer `@huanlin/dsh-plugin-better-locale`——ja / de / fr / pt / ko / ar / hi / id / tr / vi / th / ru / it / nl / sv / pl / zh-HK / zh-TW / zh-MO 全量词典（每种约 340 keys）；覆盖**借用 DSH 英文槽位**（DSH active=en 时生效，zh 下完全惰性、界面不混语言）；19 语言词典同时注册进 better-locale，外部 `ctx.locale.lookup('betterSidebar', key)` 调用者同样可拿覆盖文本；未安装时 `ctx.get('betterLocale')` 为 undefined、整段 no-op，zh/en 行为不变
+- 🌿 **Git 多仓库选择 + linked worktree 变更发现**（[#326](https://github.com/omdsh-dev/DSH-better-sidebar/pull/326) [#285](https://github.com/omdsh-dev/DSH-better-sidebar/pull/285)）：会话 cwd 是工作区容器（非 Git 仓库）时自动发现直接子仓库并显示**仓库选择器**——status / 分支 / 历史 / diff / 暂存 / 提交 / 还原 / cherry-pick / 文件打开全部按所选仓库线程化；linked worktree 的变更发现与按工作树操作（含延迟分页响应的事务一致性），并拒绝过期 / 可修剪的 worktree 命令目标、对单库存取失败降级
+- 🖥️ **浏览器本地回环允许清单**（[#365](https://github.com/omdsh-dev/DSH-better-sidebar/pull/365)）：新增侧边卡设置 `browserAllowedLoopback`（逗号分隔 host 或 host:port；裸 host 匹配任意端口、带有端口精确匹配）——显式信任的本地开发服务器（如 Vite）可导航，并额外获得 iframe `allow-same-origin` 令牌（模块 / HMR / fetch 管线需要真实 origin，否则白屏）；页面相对 GUI 与其他站点仍是跨源；服务端 `browser.probe` 镜像同一允许清单，本地服务器不再被误拒
+- 📝 **编辑器 Vue + 28 种 legacy 语言语法高亮**（[#202](https://github.com/omdsh-dev/DSH-better-sidebar/pull/202)）：`.vue` 映射 `@codemirror/lang-vue`（template / script / style 按 `lang` 属性分派、`<style lang="scss">` 预处理器）；零新依赖用 legacy-modes 补齐 scss/sass/less/stylus/ruby/lua/perl/r/dart/scala/groovy/powershell/diff/protobuf/cmake/pug/tcl/haskell/clojure/erlang/julia/pascal/vb/vhdl/stex/objectivecpp；语言工厂抛错降级纯文本（console.warn），不再炸编辑器；`.v` / `.m` 跨语言歧义故意不映射
+- 🔄 **编辑器预览刷新三件套**（[#215](https://github.com/omdsh-dev/DSH-better-sidebar/pull/215) [#228](https://github.com/omdsh-dev/DSH-better-sidebar/pull/228)，修复 [#167](https://github.com/omdsh-dev/DSH-better-sidebar/issues/167)）：文本预览新增**手动刷新**按钮；编辑保存后切回预览自动重载（dirty 时抑制，草稿不丢）；预览模式下保存成功边沿自动重载；移除自动轮询与 `fs.stat` 版本端点（后台 API 零流量）
+- 🖼️ **Markdown 本地 / 相对图片**（[#292](https://github.com/omdsh-dev/DSH-better-sidebar/pull/292)）：`![alt](./img.png)`、`/cwd/img.png` 与引用式 `[id]: url` 目标重写为 `/sidebar/file` 媒体 URL（会话 cwd 边界不变）——预览不再只显示 alt 文本
+- ➕ **推荐插件目录新增 ego-browser**（[#340](https://github.com/omdsh-dev/DSH-better-sidebar/pull/340)）：`@dsh-external/ego-browser` Agent 浏览器 Tab（会话侧边栏自动注册本机浏览器页，无 better-sidebar 时回退浮动浮窗）；描述词典 19 语言补全（[#371](https://github.com/omdsh-dev/DSH-better-sidebar/pull/371)）
+
+**🐛 修复**
+
+- 🛒 **DSH 市场受管安装兼容**（[#338](https://github.com/omdsh-dev/DSH-better-sidebar/pull/338)）：移除 `peerDependencies` 里的公开版 `cordis`（市场预览硬拒依赖字段出现 `cordis`，optional 无效）——npm 包满足 [dsh-community-market 安装规范](https://github.com/anywhere-labs/deepseek-harness-desktop/blob/master/dsh-community-market/docs/install-and-uninstall.zh.md)，dshfind / 1024Store 目录里的条目重新获得 `repository_backlink` 验证目标，可直接从 Desktop 市场受管安装
+- 🔤 **类型基底迁移到 `@deepseek-ai/cordis`**（[#338](https://github.com/omdsh-dev/DSH-better-sidebar/pull/338)）：`Context` = 真实 vendored cordis Context 与结构化服务面的**交集**，`ctx.betterSidebar` 类型合并改挂 `@deepseek-ai/cordis`，公开版 cordis 不再被依赖。**消费者迁移**：`import type { Context } from 'cordis'` 改为 `import type { Context } from '@deepseek-ai/cordis'`（`import type {} from 'dsh-better-sidebar'` 的类型合并方式不变）；未使用该导入的插件无影响
+- 🧩 **插件树内 `ctx.betterSidebar` 读取全面修复**（[#357](https://github.com/omdsh-dev/DSH-better-sidebar/pull/357)，修复 [#356](https://github.com/omdsh-dev/DSH-better-sidebar/issues/356)）：npm 安装的 DSH 0.1.1-rc.x（web bundle）下侧边栏页面每次加载即崩（`cannot get property "betterSidebar" without inject`）——26 处内部直读 `ctx.betterSidebar` 改走 `ctx.get('betterSidebar')`（root reflect store 解析，不受 fiber 链影响）；外部消费者 `inject: ['betterSidebar'] + ctx.betterSidebar` 契约不变
+- 🔐 **文件 API 会话工作区边界**（[#345](https://github.com/omdsh-dev/DSH-better-sidebar/pull/345)，修复 [#328](https://github.com/omdsh-dev/DSH-better-sidebar/issues/328)）：`fs.tree / fs.read / fs.write` 的 workspace 越界访问修复；媒体、HTML 预览与上传统一 real-path 符号链接校验；新增绝对路径 / 符号链接 / 上传 / 嵌套 Git 会话回归测试
+- 🪟 **面板宿主层级与视口裁剪**（[#330](https://github.com/omdsh-dev/DSH-better-sidebar/pull/330) [#278](https://github.com/omdsh-dev/DSH-better-sidebar/pull/278)，修复 [#277](https://github.com/omdsh-dev/DSH-better-sidebar/issues/277)）：面板宿主层 z-index 40→25——低于 DSH cordis 动态插件面板 30，工作台不再遮挡 cordis 清单 / 审批面（AppFrame 20 之上、100+ 浮层之下）；宿主 `overflow: hidden` 裁剪视口边缘，收起的面板不再把文档撑出双向滚动（实测 `scrollWidth` 2289→1672 / `scrollHeight` 1280→1032，任意皮肤）
+- 📐 **布局推挤加固**（[#310](https://github.com/omdsh-dev/DSH-better-sidebar/pull/310) [#130](https://github.com/omdsh-dev/DSH-better-sidebar/pull/130) [#180](https://github.com/omdsh-dev/DSH-better-sidebar/pull/180)）：对话列补 `min-height: 0` + `overflow: hidden` + `overflow-wrap: anywhere`（长不可断 URL / OAuth 链接不再把 composer 与左侧设置按钮挤出视口）；layout-push effect 拆「仅设置 + 仅卸载移除」并按 `panelOpen` 门控宽度 push——右栏关闭时拖底部高度不再挤压对话区、松手瞬间不再整页右铺再回弹；`useLayoutEffect` 消除跨 paint 全宽闪帧；松手 flush 最终帧 + `centerRect.right` 同步提交；底部高度按 `viewportHeight - PANEL_MIN` 封顶；拖拽手柄拖动中不再高亮
+- 📱 **移动端无会话状态说明 + 1px 溢出修复**（[#254](https://github.com/omdsh-dev/DSH-better-sidebar/pull/254)）：无会话时开关改用 `aria-disabled` 保持不可执行语义、同时允许触摸 / 键盘聚焦显示「选择一个会话以使用侧边栏」提示；panel 改 `border-box`——移动端 `100vw` 含左边框，不再产生 1px 横向溢出
+- 📏 **侧边栏宽度跨会话共享**（[#36](https://github.com/omdsh-dev/DSH-better-sidebar/pull/36)）：面板宽度是布局偏好而非会话内容——「最后一次拖拽胜出」写入全局 `dsh-sidebar:v1:width`，缓存会话切换与新建会话即时跟随；无全局键（首次运行 / 旧会话）时行为逐字节不变
+- 🧹 **会话删除立即关闭该会话终端**（[#130](https://github.com/omdsh-dev/DSH-better-sidebar/pull/130)）：新增 `PtyManager.closeSession()` + 订阅 DSH `session/disposed`——删除会话不再等 30s 重连宽限到期（agent 终端由 agent 生命周期管理，不受影响）
+- 🔍 **文件名搜索跳过噪声目录**（[#342](https://github.com/omdsh-dev/DSH-better-sidebar/pull/342)）：`node_modules` / `.pnpm-store` / `.yarn` / `.turbo` / `.next` / `dist` / `build` / `coverage` 等黑名单（小写不敏感，`.git` 仍跳）——超大依赖树不再耗尽 10 万访问预算提前 `truncated`，`docs/` 等后序目录里的真实文件能搜到；不引入 `.gitignore` 语义，保持「文件名查找」
+- 📝 **mermaid 全局错误渲染抑制**（[#341](https://github.com/omdsh-dev/DSH-better-sidebar/pull/341)）：开启 `suppressErrorRendering`——非法图表不再把大错误 SVG 注入 `document.body`；组件级错误回退与源码展示保留
+- 🖥️ **终端 Nerd Font 图标字体回退**（[#190](https://github.com/omdsh-dev/DSH-better-sidebar/pull/190)）：starship / powerlevel10k 提示符的补充平面 PUA 图标（Nerd Fonts v3 Material 图标集）不再显示豆腐块——`withIconFontFallbacks()` 为胜出的基础字体追加 Nerd Font 图标族（插入首个通用族之前、按族名去重、过滤 CSS 全局关键字、不列彩色 emoji 字体）
+- 🌐 **HTML 预览 UTF-8 声明**（[#193](https://github.com/omdsh-dev/DSH-better-sidebar/pull/193)，修复 [#170](https://github.com/omdsh-dev/DSH-better-sidebar/issues/170)）：`/sidebar/html` 响应带 `charset=utf-8`（无 `<meta charset>` 的中文片段不再乱码），保留原始文件字节
+- 🧪 **trust-fence Origin 改按 hostname 比较**（[#182](https://github.com/omdsh-dev/DSH-better-sidebar/pull/182)）：Edge 151 把非默认端口 loopback 页面的 Origin 序列化为无端口形式——`http://127.0.0.1` 对 `Host: 127.0.0.1:3080` 不再 403（对齐 DSH 官方网关栅栏）；不同 hostname / opaque null origin 仍拒绝
+- 🪟 **「在文件夹中显示」改为资源管理器揭示**（[#94](https://github.com/omdsh-dev/DSH-better-sidebar/pull/94)）：不再把目录当文件开进编辑器（`"..." is a directory`）——`revealInExplorer` 切到资源管理器 tab、面板折叠时自动展开、展开父目录并高亮滚动到本轮产出文件；产物行数据改读引擎 Turn deliverable（与 ui-deliverables 同源）
+- 🖱️ **面板拖动布局闪烁**（[#180](https://github.com/omdsh-dev/DSH-better-sidebar/pull/180)）：右侧栏关闭时拖底部高度不再左移挤压对话区；松手瞬间不再整体右铺再回弹
+- 🖥️ **PowerShell 安装脚本修复**（[#47](https://github.com/omdsh-dev/DSH-better-sidebar/pull/47)）：远程入口统一为「下载脚本 → 移除 UTF-8 BOM → 内存执行」，`-Version` / `-DryRun` 参数在 Windows PowerShell 5.1 下恢复生效（BOM 解析不再吃掉首行 `param(...)`）；安装前校验 `pnpm --version`（主版本 <10 时明确报错并以退出码 1 结束，不再写一半 profile）
+- 🔄 **浏览器嵌入探测 GET 兜底**（[#69](https://github.com/omdsh-dev/DSH-better-sidebar/pull/69)）：HEAD 响应同时缺 CSP 与 X-Frame-Options 时回退 GET 重试一次——阿里云百炼等只在 GET 回头发嵌入策略的站点不再显示误导性「拒绝连接请求」，而是正确显示「该站点拒绝嵌入」面板 + 「在浏览器中打开」
+- 🔧 **git 源安装修复 `unrun` devDependency**（[#336](https://github.com/omdsh-dev/DSH-better-sidebar/pull/336)）：tsdown 0.22 经 `unrun` 加载配置而 pnpm 11 不自动装 peer——git-hosted 安装的 `prepare` 不再报 `Failed to import module "unrun"`（npm tarball 不受影响）
+- 🍃 **`ctx.effect` 严格化顺手修了 4 处**：拦截注册失败时 effect 体返回 `undefined` 改为 no-op disposer（vendored cordis 的 effect 契约要求返回 disposer，返回 `undefined` 属非法形状）
+
+### v0.15.2
+
+自 v0.15.1 以来的全部更改：
+
+**✨ 新功能**
+
+- 🗂️ **文件树「在应用中打开」子菜单**（[#334](https://github.com/omdsh-dev/DSH-better-sidebar/pull/334)）：文件树右键菜单新增「在应用中打开 >」子菜单——内置打开方式（资源管理器显示/选中、VS Code、Cursor、Zed），每行右侧图钉可固定为右键菜单顶层直达项（再点取消）；配置可选 SSH host 后 VSCode 系条目改用 `vscode-remote/ssh-remote+<host>/<path>` 协议打开，本地专用条目自动隐藏；支持自定义编辑器（名称 + URL 模板 `{path}` + 是否 VSCode 系，配置入口在 Files 卡片齿轮弹窗）。打开动作经新宿主路由 `POST /sidebar/api/open.external`（argv 数组 spawn，无 shell 注入）（[设计文档](docs/plans/2026-08-22-open-with-menu-design.md)）
+- 📑 **Tab 右键菜单**（[#331](https://github.com/omdsh-dev/DSH-better-sidebar/pull/331)）：页签右键提供「关闭 / 关闭其他页签 / 关闭左侧页签 / 关闭右侧页签」，作用范围为当前 pane（标签组），无可关对象时置灰；仅打开菜单、不切换激活页签；批量关闭逐条走既有 `onClose` 路径，生命周期完整
+- 📄 **Diff 文件默认折叠**（[#270](https://github.com/omdsh-dev/DSH-better-sidebar/pull/270)）：改动文件头部改为可访问的展开/折叠控件；识别出的源文件默认展开，测试 / 文档 / 生成文件 / lockfile 与未知类型默认折叠；保留现有 500 行上限

+
+**🐛 修复**
+
+- 🪟 **空分栏清理**（[#268](https://github.com/omdsh-dev/DSH-better-sidebar/pull/268)）：持久化的 split pane 在临时 diff tab 被清理后遗留全尺寸空分栏——`sanitizeState` 现在同时修剪空的 split leaf，并修复修剪后的失效激活 pane 指针；整个工作台为空时保留唯一空 pane
+- 🖥️ **Windows 下隐藏 Git 子进程窗口**（[#301](https://github.com/omdsh-dev/DSH-better-sidebar/pull/301)，关闭 [#124](https://github.com/omdsh-dev/DSH-better-sidebar/issues/124)）：`runGit()` 统一加 `windowsHide: true`，仓库状态轮询与操作不再闪现控制台窗口（其他平台行为不变）
+- 📁 **未跟踪文件夹内文件差异**（[#242](https://github.com/omdsh-dev/DSH-better-sidebar/pull/242)）：`git status` 从 `--untracked-files=normal` 切换为 `--untracked-files=all`——新文件夹内每个文件独立成行、可正常加载差异（修正 `fs.read` 报 "is a directory"，与 VSCode 默认行为一致）
+- ⚡ **开关/拖拽每帧 React 重渲染消除**（关闭 [#315](https://github.com/omdsh-dev/DSH-better-sidebar/issues/315)）：centerRect 改 ref + 底栏 DOM 直写（零 React 渲染）；TabContent memo（显式比较器）；新增 frame-batcher 对 Divider/dock 拖拽按帧合并；拖拽期跳过无意义 locate。4x CPU 节流 A/B：开关 >17ms 帧 collapse 19→6 / expand 24→4~6，p95 21ms→15ms；拖拽不变（非回归）

+
+**✨ 新功能**
+
+- 💬 **侧边对话 Codex 风格转录重构**（[#314](https://github.com/omdsh-dev/DSH-better-sidebar/pull/314)）：转录改为**折叠行**——工具调用 / 思考 / 上下文注入统一为安静的单行 chrome（chevron + 标签 + 单行参数摘要，展开为 hairline 缩进正文，无卡片无填充），流式标签与创建 shimmer（shimmer = 生成中）、失败工具 danger、`prefers-reduced-motion` 停帧；**首条问题不再被边界提示吞掉**——上下文注入与首问拆分交付（边界 + 快照经 `agent.inject` 排队、问题唤醒驱动），转录把注入映射为可折叠注入行、真实用户消息（**含首问**）渲染为用户气泡，旧线程的首问同样拆分为独立气泡
+- 📖 **README 重写**：功能导览（逐特性实机截图）、用户视角 DSH 兼容徽章、简化安装流程（`add` → `approve-builds` → `add`、node-pty 安全构建、粘贴到 DSH 安装提示）、插件生态 28+ 与分类折叠展示
+
+**🐛 修复**
+
+- 🖥️ **终端跨会话切换保活**（[#323](https://github.com/omdsh-dev/DSH-better-sidebar/pull/323)）：切到其他会话不再被当作瞬时掉线——客户端卸载时发送 `park` 控制帧，主机跳过 30s 重连宽限倒计时；切回会话（`open()` 取消 parked）或显式关闭恢复正常生命周期；agent 终端保持无限期存活
+- 📂 **文件树上传遮罩不再拦截 Tab 拖拽**（[#317](https://github.com/omdsh-dev/DSH-better-sidebar/pull/317)）：拖拽 Tab（重排 / 跨 pane split）经过资源管理器时不再弹上传遮罩、不吞事件——统一按 `dataTransfer.types` 含 `Files` 门控（与面板宿主 shield 一致），Tab 正常落下；OS 文件拖拽行为不变
+- 💬 **子代理自动展开去抖**（[#314](https://github.com/omdsh-dev/DSH-better-sidebar/pull/314)）：Side Chat 线程创建不再误弹任务页——0→N 触发 500ms 重臂并对实时快照按原基线重评估，标题过滤器识别线程后才放行；真实子代理依然自动激活任务页（宽屏展开侧边栏，窄屏只准备 Tab、不强制展开抽屉）
+
+### v0.15.0
+
+自 v0.14.0 以来的全部更改：
+
+**✨ 新功能**
+
+- 💬 **侧边对话(beta) Tab**（[#286](https://github.com/omdsh-dev/DSH-better-sidebar/pull/286)）：Codex 风格的侧边线程，**每个对话一个独立 Tab**——子会话继承主会话完整上下文（已完成回合 + 未回答消息 + 进行中回合的 assistant 输出与工具调用，以「interrupted」冻结标记诚实继承）；同组合创建（同 preset / provider / model）复用前缀输入缓存；线程对主会话列表不可见、零子代理目录噪音；线程内可持续追问（重启后自动冷恢复）；一键「保存为新会话」提升为顶层会话（[设计文档](docs/plans/2026-08-20-sidechat-tab-design.md)）
+- 📤 **文件窗口上传**（[#239](https://github.com/omdsh-dev/DSH-better-sidebar/pull/239)）：头部「上传文件 / 上传文件夹」按钮 + 拖放上传（拖到树区 = 工作区根，目录行 = 进该目录，文件行 = 进其所在目录，对齐 VSCode）；上传时全屏模糊进度弹层（文件级进度 + 取消 / Esc）；上传中按钮禁用、成功后文件树自动刷新
+- 🧩 **桌面兼容四选项**（[#284](https://github.com/omdsh-dev/DSH-better-sidebar/pull/284)）：位置兼容模式改为**主行下拉**——**自动检测**（默认，保守：仅使用标准的 Window Controls Overlay 几何，32/36px 等各壳差异自动跟随、最大化/还原实时更新，网页环境零修改）/ **DSH官方Web**（显式零适配）/ **壳兼容方案**（内置预设，手动启用；只收录 issue/PR 中出现过且 100+ star 的壳，命中环境带「已检测」提示）/ **自定义方案**（自定义 CSS + 下移距离）。旧版本已有兼容配置的用户自动落到自定义方案；交互控件统一退出桌面拖拽区（`no-drag`）；底栏推挤锚点复合选择器双保险（`[data-pane]` 与 `:has(> [data-slot])`）
+- 🎛️ **设置页 UI/UX 现代化**（[#300](https://github.com/omdsh-dev/DSH-better-sidebar/pull/300)）：侧边卡片二级设置入口改为卡片底部「功能设置」设置条（替代右下角隐形齿轮，可发现性提升）；协调双色启用态（brand 激活强调 + success 绿勾选徽标）；全部颜色仍为 `--dsw-alias-*` 令牌派生，皮肤体系自动跟随
+- ➕ **推荐插件目录新增**：`dsh-docs-panel` 全局文档面板（[#230](https://github.com/omdsh-dev/DSH-better-sidebar/pull/230)）、`dsh-flowglass`（[#261](https://github.com/omdsh-dev/DSH-better-sidebar/pull/261)）、`dsh-git-forge` 与 `dsh-ssh-tunnel`（[#204](https://github.com/omdsh-dev/DSH-better-sidebar/pull/204)）、`dsh-turn-review`（[#102](https://github.com/omdsh-dev/DSH-better-sidebar/pull/102)）

+**✨ 新功能**
+
+- 🖼️ **统一面板宿主注入重构**（[#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)）：面板/开关簇迁入 `[data-dsh-panel-host]` 固定含块层（`fixed inset-0 z-40`），免疫桌面套壳中间层 transform 对 fixed 含块的劫持；挂载自检（页面级 transform → `data-dsh-panel-host-degraded` 降级同步，按未修正几何判定、祖先变换消失才退出）；推挤锚点改 `#root [data-dsh-frame] > [data-pane="conversation"]` + `#root` calc 宽度防桌面壳加性溢出；chunk 激活重验证（HEAD+ETag 保留未变 chunk，5s 超时兜底 fail-open）；`visualViewport` 键盘 inset + `env(safe-area-inset-*)` 移动端适配

+
+**🐛 修复**
+
+- 🧩 **rc.8 模块系统迁移**（[#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)）：rc.8 不再暴露 `window.__DSH_MODULES__` 页面全局（改由 `ctx.modules` 服务提供），懒加载 chunk 的外部依赖解析全面失效——client 注入 `modules` 服务 + 插件自有全局共享给 chunk 副本（终端 / 编辑器 / Mermaid 恢复正常按需加载）
+- 🧩 **chunk 重验证屏障健壮性**（[#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)）：HEAD 重验证加 5s 超时兜底（路由挂起时 fail-open 重取，屏障不再可能无限期阻塞懒加载）；`resetChunks` 清挂起的重验证屏障

+- 📊 **Markdown 预览安全渲染 Mermaid 图表**（[#164](https://github.com/omdsh-dev/DSH-better-sidebar/pull/164)）：预览的 md 含 mermaid fence 时按需下发 `client-mermaid.js` chunk（~7MB，无 mermaid 文件零加载）；纵深防御渲染——`securityLevel: 'strict'` + `htmlLabels: false`（节点文字走真实 SVG `<text>`）+ SVG 注入前二次清洗（删 `foreignObject`/`script`/外来 HTML 元素、剥 `@*`/`on*`/`href` 属性）；点击图表在弹窗中放大（滚轮以鼠标为中心缩放、拖拽平移、工具栏与快捷键），深浅色跟随重渲、解析失败回退原码
+- 🖥️ **终端 shell 与 shellArgs 可配置**（[#125](https://github.com/omdsh-dev/DSH-better-sidebar/pull/125)）：`cordis.patch.yml` 的 `better-sidebar.config` 可指定 `shell` / `shellArgs`（`shellArgs` 非空时完全替换默认参数；未配置维持自动解析 `$SHELL` / 登录 shell / `powershell.exe` 原行为），UI 终端与 agent 终端（`terminal_create`）同时生效；终端 tab 标题改用 shell 名（bash / zsh / powershell），内部标识改 UUID，同 shell 可开多个终端
+
+**🐛 修复**
+
+- 🔗 **聚合双挂载自动退让**（[#200](https://github.com/omdsh-dev/DSH-better-sidebar/pull/200)）：聚合包（如 dsh-web-ui-all）以独立条目 id 挂载同包时，`cordis.patch.yml` 的守卫表达式自动禁用自身 `better-sidebar` 行，不再重复注册 `/sidebar/api` 导致 `duplicate prefix route` 整个插件树启动失败（`dsh web` 崩溃）；独立安装行为不变
+- 🔧 **适配 DSH 0.1.0-rc.7**（[#207](https://github.com/omdsh-dev/DSH-better-sidebar/pull/207)，修复 [#206](https://github.com/omdsh-dev/DSH-better-sidebar/issues/206)）：修复 DSH 主框架升至 rc.7 后选模型 / 发消息报 `agent-presets: refusing to compose an unscoped context` 的问题

+
+**✨ 新功能**
+
+- 📁 **文件窗口与资源管理器二合一**（[#151](https://github.com/omdsh-dev/DSH-better-sidebar/pull/151)）：新 `editorExplorer` 设置（编辑器卡齿轮）——文件 tab 增加路径输入框头部 + 可开关的右侧停靠文件树（每 tab 记忆展开/宽度，左缘拖拽调宽 160~480px，全局文件名搜索走 host `fs.search` 路由，预算封顶并跳过 `.git` / 符号链接目录）；独立模式（默认）树点击 / 输入框 Enter **按路径新开**文件 tab，合并模式**原地切换**当前 tab；新会话默认 seed 空文件窗口（`Files`）替代 explorer tab，无路径窗口在独立模式为纯资源管理器、合并模式为带 chrome 的空文件窗口；树右键提供「在新 Tab 中打开」「在侧边打开」（split）
+- 🎛️ **声明式设置 select 行**（[#151](https://github.com/omdsh-dev/DSH-better-sidebar/pull/151)）：设置项新增 `type: 'select'`（`options` 支持 value/title/desc/icon，`multi` 多选存数组）；带图标的选项渲染大图标选项卡、收起态同样显示图标；`editorExplorer` 改为图标化下拉（合并 / 独立）；能力清单新增 `settingSelect`
+- 🔀 **与 dsh-web-ui 家族右侧面板互斥**（[#181](https://github.com/omdsh-dev/DSH-better-sidebar/pull/181)）：读取 `aionui-panel` 设置命名空间的提供方选择——当选择「使用 aionui-panel」时，整个 better-sidebar（右侧栏 / 底部面板 / 浮动入口 / 各类接管）不再挂载；选择 DSH-better-sidebar（或未安装 aionui）时正常。设置页保存后实时生效（settings-document 推送），无需刷新

+
+> Full release history of dsh-better-sidebar (see the [README](README_EN.md) for the latest release; also mirrored on [GitHub Releases](https://github.com/omdsh-dev/DSH-better-sidebar/releases)).
+
+### v0.20.0 (dev line, **never published**)
+
+> 🚫 **This version never reached npm** (npm `latest` is still v0.19.1): it was meant to be the stable release on the 0.1.6-alpha.2 line, but the 0.21 line replaced it before release, so everything below actually shipped in **v0.21.1**. Its original positioning: supports **DSH 0.1.6-alpha.2+** only (peer floor `^0.1.6-alpha.2`, CI pins `@deepseek-ai/dsh@0.1.6-alpha.2`). **This is a breaking-change release**: hosts on 0.1.5-rc.* should pin `dsh-better-sidebar@0.19.1`. See [docs/plans/2026-09-21-dsh-0.1.6-alpha.2-adaptation.md](docs/plans/2026-09-21-dsh-0.1.6-alpha.2-adaptation.md) for the adaptation record.
+
+- 🖥️ **Terminal handed to DSH's built-in**: DSH 0.1.6 ships its own right-column terminal (`ui-sidebar-terminal`), so the plugin deleted its whole terminal stack — `pty-manager` / `agent-pty` / `pty-deps` / the 8 `terminal_*` tools / the xterm view and font-linking / cross-session terminal pinning — along with the `node-pty` dependency, its `allowBuilds` grant and the installer's `-Repair` mode. **Note**: the model therefore loses a cross-call persistent terminal (only one-shot `bash` / `pwsh` remain); the upstream `@deepseek-ai/dsh-tool-terminal` is not mounted by any shipped bundle, so enable it yourself in the profile when you need it.
+- 🌐 **Browser view handed to the built-in**: the plugin deleted `BrowserView` / the sandbox status bar / the embeddability probe (including the host's `browser.probe` route) and the two settings that only configured its own iframe; it **keeps** the external-link takeover in the chat and UI (protocol-based routing is the capability the host does not have), now targeting DSH's built-in `browser` tab type.
+- 🧩 **The produced-files row goes back to the host**: DSH 0.1.6 turned `conversation.chat.turnTail` from a chain into a list (upstream deliberately lets several plugins **append** rather than replace each other), so the plugin's takeover could only duplicate the built-in deliverables card and was removed wholesale; click behaviour is unchanged (the built-in goes through the host's `openFile` → this plugin's editor). The cost is the one "reveal in the file tree" entry at the turn tail (the in-tree context menu remains).
+- 🐛 **Two silent breakages fixed**: once `SidebarRightGuideEntry.id` became required, a missing id left the **whole native surface silently empty** (the throw happens inside an `ctx.inject` callback and is swallowed); once `turnTail` became a list the old registration threw outright and the row died. Both are fixed and guarded by tests, with a registration-failure reporting hook added alongside.
+- 🎨 **The empty-pane card now matches the built-in card recipe**: `.paneCard` adopts DSH's guide-capsule recipe (0.5px l4 border / 24px radius / layer-1 fill / 56px minimum / 14×20 padding), with tests guarding its geometry, its tokenized colours, and that it does not copy upstream's **undefined** `--dsw-alias-bg-l1/-l2` spellings.
+- 📐 **Baseline**: every `@deepseek-ai/dsh-*` package is pinned to `0.1.6-alpha.2`, the vanished `dsh-code-runtime` package is removed, `diff` / `simple-icons` are hoisted into devDependencies as primitives' new bare imports, and `ui-primitives`' three breakages this release (`IconSendOutline16` gone, `TerminalBlockLabels.noExitCode` added, `ConnectionIndicator.reconnectLabel` removed) are adapted.
+
+### v0.19.1
+
+> 📌 **Stable release** (npm `latest`, no prerelease suffix): the pinned baseline moves to **DSH 0.1.5-rc.2** (npm `next`) while the **peer floor stays `^0.1.5-rc.1`** — nothing in the rc.2 upstream delta touches this plugin (zero changes under `packages/api|host|session|agent`; the only real code edits are the message-feedback dialog, deliverables card CSS and the `CodeFileIcon` SVG data split), so rc.1 hosts need no DSH upgrade to run this version. Hosts on DSH 0.1.5-alpha.2 stay on **v0.19.0-alpha.1**; the 0.1.2-rc.1 stable line keeps using **v0.18.1**.
+
+- 🎯 **Adapted to DSH 0.1.5-rc.2**: devDependency pins, the CI mount lane and `SIDEBAR_SERVICE_VERSION` all move to rc.2; there is **no plugin-side code change** (the upstream delta does not touch this plugin — file-by-file audit in [docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md](docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md): the vast majority of the 300 changed files are single-line `version` bumps).
+- 🎨 **File icons (#611) and the built-in tab glyphs are now colored** (#531 + #594 merged, implementation redone for rc.2):
+  - **Files and folders use DSH's own artwork**: the fallback link is the host's `FileTypeIcon` from `ui-primitives` (48 full-color official code/config glyphs plus the category-colored sheets for markdown, images, PDF, Office, video and folders), so the plugin **ships no extension table and needs no icon chunk** — #429's 563-entry color dataset and `lib/client-file-icons.js` (255 kB) are gone, along with the `fileIconTheme` switch. Color is simply the behaviour now, and the core bundle grew by 10 kB.
+  - **New public `registerFileIcon` API** (capability `'fileIcons'`): register your own glyphs by extension (`exts`), exact file name (`names`) or directory name (`folderNames`), ranked by priority then registration order. **Caveat**: the host classifier covers every path, so a catch-all (`exts: []`) claims every row the specific rules miss.
+  - **Colored built-in tab glyphs**: Files / Changes / Tasks / Side chat / Terminal / Browser and the diff view all get a colored glyph, painted from `--dsw-alias-*` tokens so every skin still applies.
+  - **The native right Sidebar's tab chips carry a glyph too**: the host's tab definition has no icon field, but the `sidebar.right.pane.tab.title` slot *is* the chip's content — the plugin renders `[glyph][title]` there (an editor tab with a path shows that file's icon). The glyph is `aria-hidden`, so the chip's accessible name is unchanged.
+- 🛠 **CI fix 1: real Windows-lane timeouts**. `ci-windows` went red eight times in the 2026-09-09/10 window; six of those were process-spawning cases hitting vitest's 5000 ms default: `tests/agent-pty.spec.ts` (real PowerShell + ConPTY per terminal) and `tests/install-powershell.spec.ts` (a cold `powershell.exe` start measured 12.1 s) now declare a 30 s budget each, vitest.config.ts raises the global `testTimeout` from its 5000 ms default to **15 s** (the first real Windows run then lost a *third* file to the same default — `tests/git.spec.ts:85` at 9607 ms; three files, one cause, so per-file patches were whack-a-mole), and `waitForTranscript`'s inner poll budget dropped from 5000 ms to 15 s — **the inner budget must sit below the outer one** (they used to be the same 5000 ms, a structurally guaranteed timeout). `ci-windows`'s `Test` step now runs `pnpm test:windows` (`--maxWorkers=2`) so the process-spawning specs stop starving each other on a 2-core runner.
+- 🛠 **CI fix 2: the mount lane's npm install**. `plugin-mount`'s `npm install -g @deepseek-ai/dsh@<ver>` failed four times (two `ETARGET`, two `JavaScript heap out of memory` / exit 134): the pinned version declares its transitives as floating `^` ranges, so while upstream publishes a prerelease in stages (rc.2 appeared package by package between 14:43 and 14:57 UTC on 09-10) npm resolved a mixed rc.1/rc.2 peer graph (3062 ERESOLVE lines). The lane now pins an **already-complete** rc.2 (fixes ETARGET) and passes `NODE_OPTIONS=--max-old-space-size=4096` (fixes the OOM). `--legacy-peer-deps` was tried on the way and rejected by real CI: it skips exactly the peers a global install must supply, and `@deepseek-ai/cordis-plugin-group` — required at boot by `dsh-app-boot` — is a peer rather than a dependency, so the CLI died with `ERR_MODULE_NOT_FOUND`.
+
+### v0.19.0
+
+> 📌 **Stable release** (npm `latest`, no prerelease suffix): supports **DSH 0.1.5-rc.1+** only (peer floor `^0.1.5-rc.1`, CI pins `@deepseek-ai/dsh@0.1.5-rc.1`). Hosts on DSH 0.1.5-alpha.2 should stay on **v0.19.0-alpha.1** (the npm `alpha` tag still points there); the 0.1.2-rc.1 stable line keeps using **v0.18.1**.
+
+**✨ New**
+
+- 📝 **The new-tab list gets an optional description back**: DSH 0.1.5-rc.1 restored `SidebarRightGuideEntry.description` (optional), so the plugin restores `TabDescriptor.description` — each of the six built-in types declares a line again (all six guide rows — Files / Changes / Tasks / Side chat / Terminal / Browser — carry one), and the `guideDesc*` keys return to all 20 dictionaries. **The host's native guide renders descriptions only while the listed entries are ≤ 4** (a longer list drops every description rather than truncating), and the plugin contributes six guide entries by default — so in the default composition no description is rendered; they appear once the reader disables enough tab types (per-type switches live on the plugin's settings page) to bring the guide down to four entries or fewer. An entry that declares none stays a single icon + title line (the plugin ships no generic fallback sentence). (#613)
+
+**🐛 Fixes**
+
+- None. The rc.1 delta over alpha.2 is small (373 changed files, overwhelmingly upstream package version bumps, native-sidebar preview UI polish, and test snapshots); apart from the restored description field (plus upstream's `files` type now using its own coloured folder glyph as the guide glyph) nothing needed adapting.
+
+**🧰 CI & internals**
+
+- Baseline moved to **DSH 0.1.5-rc.1+** (#613): peer floor, devDependency pins, the CI mount lane, and `dsh.plugin.json`'s `engines.dsh` all follow (rc.1 is both the `latest` and `next` dist-tag on npm).
+- Explicitly unchanged, no need to re-check: the global main-panel model (the `main` slot / `sidebar.panellist` / `ctx.layout` / root-scoped `rightbar` + `rightbar.session`, still not adopted), the file address grammar (`packages/util/workspace-path` only had its version bumped), the native tab-body host contract (`.paneBody` is still a block scroller with a definite height), the core / agent / session / subagent host APIs, and the `ui-primitives` export surface (only CodeBlock rendering changed).
+- `@deepseek-ai/dsh-client-ui-primitives@0.1.5-rc.1` still declares no `dependencies` while its bundle still bare-imports `anser` / `shiki` / `@shikijs/langs/*` / `mdast-util-*` / `micromark-*` / `katex` — the third-party devDependencies hoisted in the previous release therefore stay, and must not be reverted.
+- Real-host verification (DSH 0.1.5-rc.1 + plugin 0.19.0): `typecheck` / `lint` / `check:consumer-types` green; unit suite **124 files · 1296 passed · 9 skipped**; `pnpm peers check` clean; the mount smoke lane against real rc.1 **7 passed** (including the tab-body fill assertion and the new "descriptions render only at ≤4 guide entries" assertion); on the local 3080 instance the guide still shows six icon+title capsules (6 > 4, so upstream renders no descriptions — upstream also raised the capsule `min-height` from 48px to 56px), clicking `AGENTS.md` in the file tree lands in the plugin editor (CodeMirror mounted), the side-chat composer sits on the pane floor (host box 962px == pane body 962px, composer 8px off the bottom), the bottom workbench's edges coincide with the centre column, and `pageerror` is 0 (the only console noise is the third-party `dsh-tauri-worktree` `/api/dsh-worktree/attach` 500, unrelated to this change).
+
+### v0.19.0-alpha.1
+
+> 🧪 **alpha channel** (npm dist-tag `alpha`, install `dsh-better-sidebar@latest`): supports **DSH 0.1.5-alpha.2+** only (peer floor `^0.1.5-alpha.2`, CI pins `@deepseek-ai/dsh@0.1.5-alpha.2`). Stay on **v0.19.0-alpha.0** for 0.1.5-alpha.1; the 0.1.2-rc.1 stable line keeps using **v0.18.1** (npm `latest`).
+
+**✨ New**
+
+- 🪟 **Every tab body now fills its pane** (#609): the native sidebar's tab-body host is a block scroller with a definite height, not a flex container, and the plugin's tab roots declared only `flex: 1` — so they collapsed to content height and the side-chat composer sat right after the transcript instead of at the pane bottom (a long transcript pushed it out of view). The native adapter now wraps every tab body in a `height: 100%` column flex host, restoring the same fill semantics the bottom workbench has for all plugin tabs, third-party `registerTab` descriptors included.
+
+**🐛 Fixes**
+
+- 🧭 **File address grammar follows DSH 0.1.5-alpha.2**: `fileAddressFor` always produces a session-scoped address and absolute paths keep their leading `/`; `parseFileAddress` is prefix-based and ignores `?`/`#` suffixes.
+- 🪟 **Center-column anchor follows alpha.2's global panels**: the `conversation` slot became `main.conversation` under the root-scoped keyed `main` slot, so the locator now resolves the new key and skips `display: contents` slot hosts (alpha.1's old key still works).
+
+**🧰 CI & internals**
+
+- Baseline moved to DSH 0.1.5-alpha.2 (#609): peer floor, 22 devDependency pins, the CI mount lane, and `dsh.plugin.json` engines all follow; `pnpm peers check` is clean (hoisted the `dsh-session-persistence` transitive peer per §3-9).
+- **`TabDescriptor.description` removed**: alpha.2's native guide entries no longer render a second line (they are icon + title capsules), so the field and the six `guideDesc*` keys (20 dictionaries) are gone; a new pane's default page is now selected from the registry (exactly one guide entry opens that page directly).
+
+### v0.19.0-alpha.0
+
+> 🧪 **alpha channel** (npm dist-tag `alpha`, install `dsh-better-sidebar@latest`): supports **DSH 0.1.5-alpha.1+** only (peer floor `^0.1.5-alpha.1`, CI pins `@deepseek-ai/dsh@0.1.5-alpha.1`). The 0.1.2-rc.1 stable line keeps using **v0.18.1** (npm `latest`).
+
+**✨ New**
+
+- 🖥️ **DSH's native right sidebar** (#604): the right column is now DSH's own sidebar — all seven plugin tab types register as native tab types with native tab bodies; every file open from the chat goes through `ctx.sidebarRight.openResource(dsh-resource://file/…)`; the `editor` type claims file resources at `extension` priority (outranking the built-in text preview) and takes over the built-in Files page kind (restored on unregister); cross-session opens queue until the target session is on screen.
+- 🧩 **Own right panel and free windows retired** (#605): with the right column handed back to DSH, the plugin keeps only its bottom workbench (single split tree, per-session persistence) and registers its toggle into DSH's session-header utilities slot; the float API (`floats` / `floatTab` / `dockFloat` / `raiseFloat` / the "Move to Free Window" menu entry), the `'floatWindows'` feature string, and the `openByDefault` / `defaultWidthPercent` / `changesDiffFloat` settings are gone (a persisted `floats` field is ignored, so old documents still load).
+- 🔗 **DSH 0.1.5 host contracts** (#603): the `assistant/chunk` event is gone — live deltas now fold from `agent/assistant-stream` frames (the side chat transcript's `live` field); `sessionPersistence.inspect` is gone — cold reads go through `open(id,'read')`; session headers use `SESSION_FORMAT_VERSION`.
+
+**🐛 Fixes**
+
+- Eight session-event read sites follow the 0.1.5 contracts (side-chat transcript, `jobs.output` replay, fork inheritance); custom seeds now carry the fork marker pair, so they no longer inherit the parent's unclaimed inbox input.
+
+**🧰 CI & internals**
+
+- The real-host mount smoke lane pins 0.1.5-alpha.1 and sweeps the native sidebar's guide page to open every plugin tab type; typecheck / lint / unit tests / mount lane all green.
+
+### v0.18.1
+
+> 📌 **Stable release** (npm `latest`): the DSH baseline is unchanged (**0.1.2-rc.1+**, peer floor `^0.1.2-rc.1`) — this is the incremental cut after v0.18.0: richer op previews in the changes panel, a writable file tree, and five fixes.
+
+**✨ Features**
+
+- 📄 **Op-preview upgrades in the changes panel** (#499): markdown reading mode with mermaid fences, plus inline `.html` and `.pdf` render previews; diff syntax highlighting extended to mjs/cjs/mts/cts, CSS/SCSS/Less, HTML/XML/SVG/Vue, GraphQL, JSONC/JSON5; new **secret redaction** layer (on by default for previews, toggleable in the pane header)
+- 🗂️ **File-tree rename / delete** (#550): inline rename plus confirmed delete, slimmer context menus and viewport-clamped submenus
+- 🧩 **Plugin catalog names and shell preset text localized** (#535): they now follow the host language
+
+**🐛 Fixes**
+
+- 🔀 **Git diff gap folds really expand** (#576, fixes #577): the fold row promised "n lines… click to expand" but did nothing (`-U3` leaves gap segments without row text); the hidden rows now load on demand through `git.show`, sliced from both sides' contents, with loading / failure states and request deduplication — plus a fix to that route's `rev:path` addressing (it always returned empty before)
+- 💬 **Side-chat seeds no longer inherit the parent's unclaimed inbox messages** (#562): the seed carries the fork markers, so the "side chat sends earlier User messages first on long contexts" ghost message is gone
+- 🖼️ **Local images in the split markdown renderer** (#569): rewritten to reachable URLs instead of 404ing
+
+**🧰 CI and internals**
+
+- ESLint flat config wired into CI and the Makefile (#536), Makefile command surface (#526), hardened e2e scripts (#527), shared component-test utilities (#524)
+- Refactors: Sidebar.tsx split by concern (#542), four polling idioms converged onto `use-polling` (#541), rc.7 `__DSH_MODULES__` fallback removed (#540), One Dark/Light syntax palettes single-sourced (#534), duplicated implementations converged and dead code removed (#525)
+
+### v0.18.0
+
+> 📌 **Stable release** (npm `latest`): this release targets **DSH 0.1.2-rc.1+ only** (peer floor `^0.1.2-rc.1`); 0.1.0-rc.8 ~ 0.1.1-rc.2 are not supported — stable-DSH users should stay pinned to `dsh-better-sidebar@0.17.1`, hosts on 0.1.2-alpha.x keep `dsh-better-sidebar@latest` (v0.18.0-alpha.0).
+
+All changes since v0.17.1 (the two intermediate version numbers v0.18.1-alpha.0 / v0.19.0-alpha.0 were never published; their content is folded into this release):
+
+**🔗 Host track graduation**
+
+- **Onto the DSH 0.1.2 line and graduating to stable**: v0.18.0-alpha.0 dropped the 0.1.1-rc.x compatibility layer and fixed blank Side Chat transcripts on alpha.1+ (#472); the baseline then climbed through alpha.3 (#497) and alpha.5 (#516, `Session.events` → `snapshotEvents()`); the chat file-open funnel moved to `remote.session.openWorkspacePath` (#494) and the "Show in folder" reveal scroll was scoped to the tree body (#453). This release pins the baseline to **DSH 0.1.2-rc.1** (zero source delta vs alpha.5 — a pure version bump; `dsh-client-locale` resumed publishing, everything aligned to rc.1; real-host mount smoke 14/14 in CI)
+
+**✨ Features**
+
+- 🌿 **Unified "Changes" tab** (#475): one tab, two lenses — Git (real diff / history / stage·commit·revert / worktree & child-repo selection) and This Session (live tracking of every file the model reads / writes / edits); a unified diff renderer (mod pairing + intra-line character highlights + syntax coloring + context folding), a draggable bottom preview pane, and one-click expansion into a dedicated diff tab
+- 💬 **Side Chat rendering upgrade** (#486): main-conversation-grade Blocks structure, per-turn usage tails, reconnect banner
+- ⚙️ **Workspace path fence toggle** (#458): a new `workspaceFence` declarative settings key with a one-click off affordance and guidance on 403 error surfaces
+
+**⚡ Performance**
+
+- 🚀 **Core bundle -45%** (#489): 19 non-zh/en dictionary chunks lazy-loaded, render stabilization (transcript row reuse / tree Sets / batched drags), startup & polling cost cuts (single settings fetch, one git process per tick); a new perf measurement lane; also fixes the bottom-pane drag leaking panel width into the host layout and jumping the native left sidebar
+- 📉 Fewer repeated center-column DOM queries (#456)
+
+**🐛 Fixes (selection)**
+
+- ✏️ Editor / Markdown: SSH remote editor links open on the client (#522), reading position kept across preview/edit switches (#467), YAML frontmatter hidden in preview (#394), TOC dismiss-on-outside-click + popover z-index (#461), file basename kept in @-reference links (#417)
+- 💻 Terminal / platform: Windows custom shell executables resolve (#503), transient resize failures contained (#428), monospace fallback for unresolvable fonts (#366), Linux absolute paths in WSL workspaces (#455), Windows Explorer reveal selection preserved (#508)
+- 🗂️ Layout / state / file tree / chat: desktop shell layout coexists with the side card (#398), no forced mobile drawer on auto-activation (#373), restored free-window id conflicts (#385), tree auto-refresh on window focus (#469), reference affordance pinned to row tail (#509), selection-popup dismissal + caret-anchored draft insert (#427), collapsed toggle cluster aligned (#361), old-engine scroll-jump compat (#448), worktree listing on older Git (#454)
+
+**🧰 CI & internals**
+
+- Windows CI lane (#520), Makefile command surface (#526), e2e script hardening + aggregate double-mount regression (#527), shared component test utils deduplicating boilerplate (#524), duplicate-implementation convergence + dead code removal (#525)
+
+**🌐 Ecosystem**
+
+- 10+ new curated plugins: dsh-better-sidebar-icons (#441), dsh-sidenote (#451, formerly dsh-sidechat #470), dsh-github-workbench (#410), dsh-bilingual-reader (#379), dsh-server-deck (#413), dsh-md-export (#405), dsh-code-nav (#404), dsh-suhuang-scroll (#392), dsh-better-overleaf (#370), and more (each with 18+ language i18n coverage)
+
+### v0.19.0-alpha.0 (0.1.2-alpha.5 adaptation, unpublished, folded into v0.18.0)
+
+> 🧪 **Alpha track**: this release targeted **DSH 0.1.2-alpha.x only** (peer floor `^0.1.2-alpha.5`, npm dist-tag `alpha`). This number was never published separately — its content shipped in the **v0.18.0** stable release, and the same number was later reused for the 0.1.5 adaptation line (see above).
+
+- 🔗 **Adapted to DSH 0.1.2-alpha.5 (published to npm, `alpha` dist-tag)**: the CI mount gate's pin, the `dsh.plugin.json` engines floor, and the `@deepseek-ai/*` peer / devDependencies baseline moved up to 0.1.2-alpha.5 (verified by a real-host mount smoke 14/14). `dsh-client-locale` has no alpha.5 upstream (newest is 0.1.2-alpha.3), so its peer floor / devDep pin trail the baseline and already accept the alpha.5 runtime (`pnpm peers check` reports zero mismatches — no new transitive peers to hoist). The code adapts to alpha.4's compatibility-flagged change — the `Session.events` property was removed, migrated to the on-demand `snapshotEvents()` API (8 sites: sidechat transcript live reads, fork inheritance, `jobs.output` replay, subagent activity), and the `seedLength` meta field the host dropped was removed from thread creation; alpha.4's remaining changes (bidirectional `send_message`, custom-model discovery reusing Profile headers, `SessionSeq`/`SessionLogOffset` strong typing) and alpha.5's upgrade-startup fix were verified not to touch any other plugin surface.
+
+### v0.18.1-alpha.0
+
+> 🧪 **Alpha track**: this release targets **DSH 0.1.2-alpha.x only** (peer floor `^0.1.2-alpha.3`, npm dist-tag `alpha`, install `dsh-better-sidebar@latest`). This version number was never published separately; its content is folded into the **v0.18.0** stable release.
+
+- 🔗 **Adapted to DSH 0.1.2-alpha.3 (published to npm, `alpha` dist-tag)**: the CI mount gate's pin, the `dsh.plugin.json` engines floor, and the `@deepseek-ai/*` peer / devDependencies baseline moved up to 0.1.2-alpha.3 (verified by a real-host mount smoke 14/14). All 117 commits between alpha.2 and alpha.3 were audited point by point: every host contract this plugin relies on (token auth, slash RPC, `MarkdownText` labels, the event-stream and persistence APIs behind `sidechat.events`, `SettingsNamespaceInput`, `SUBAGENT_DESCRIPTOR_VERSION` (still 3), `dsh-client-store`, the profile loader, the node-pty pin) is unchanged, so no code adaptation was needed; alpha.3's breaking changes (the required `BeginSubmissionInput.mode`, the renamed `attachment-invalid` subagent error, the removed SQLite persistence backend, the identity-gated projection change feed) were all verified not to touch this plugin.
+
+### v0.18.0-alpha.0
+
+> 🧪 **Alpha track**: this release targets **DSH 0.1.2-alpha.x only** (peer floor `^0.1.2-alpha.2`, npm dist-tag `alpha`, install `dsh-better-sidebar@latest`); 0.1.0-rc.8 ~ 0.1.1-rc.2 are no longer supported — stable-DSH users should stay on v0.17.1 (npm `latest`).
+
+- 🔗 **Adapted to DSH 0.1.2-alpha.2 (published to npm, `alpha` dist-tag)**: the CI mount gate's pin and the `@deepseek-ai/*` devDependencies baseline moved up to it (verified by a real-host mount smoke 14/14). Adaptation points: `dsh-settings` dropped the runtime `settingsNamespace` export (namespaces are now validated at compile time — the host passes the constant directly); the `dsh-subagent` descriptor version went 2→3 (stamped by the host package; the test assertion follows the `SUBAGENT_DESCRIPTOR_VERSION` constant); the restored `SessionEvent.ignorable` and the Remote gateway's unified `RemoteError` wrapping were verified to not affect this plugin.
+- 🐛 **Fixed blank Side Chat transcripts on DSH 0.1.2-alpha.1+**: transcript polling still called the `ctx.connection.api` face removed in alpha.1 (the error was silently swallowed, so the tab rendered an empty transcript forever). Transcripts now come from the plugin's own `sidechat.events` route (live threads read the in-memory event log, cold threads read session persistence, with `afterSeq` delta pulls, [sidechat-routes.ts](./src/sidechat-routes.ts)).
+- 🧹 **Dropped the pre-alpha (0.1.1-rc.x and older) compatibility layer**: the e2e host RPC collapsed from the dot/slash dual dialect to slash-only (token URL required, [host-protocol.ts](./tests/e2e/host-protocol.ts)); `MarkdownText` labels collapsed to the nested single shape ([markdown-labels.tsx](./src/client/markdown-labels.tsx), no more dual prop names); peerDependencies / devDependencies / `dsh.client.inject` / the chunk externals allowlist all dropped the defunct `@deepseek-ai/dsh-client-runtime` (four synchronized spots).
+
+### v0.17.1
+
+- 🔗 **DSH 0.1.2-alpha.1 adaptation (dual-version compatible)**: fully adapted to DSH 0.1.2-alpha.1's Remote gateway, one-time-token browser authentication, and the `MarkdownText` labels contract change — the plugin works identically on 0.1.0-rc.8 ~ 0.1.1-rc.2 and 0.1.2-alpha.1 (the latter verified by a real-host mount smoke 14/14 against a source build of the GitHub tag; alpha.1 was never published to npm, and the CI pin moved to the npm-published 0.1.2-alpha.2 in v0.18.0-alpha.0). Highlights: all four `MarkdownText` render sites now go through the dual-shape labels helper ([markdown-labels.tsx](./src/client/markdown-labels.tsx)), fixing the `reading 'code'` crash in markdown/mermaid previews on alpha.1; the e2e mount smoke speaks both wire dialects (token-URL cookie exchange, slash `/api` endpoints with parameter-named args, [tests/e2e/host-protocol.ts](./tests/e2e/host-protocol.ts)); dropped the `@deepseek-ai/dsh-client-runtime` peer removed upstream in 0.1.2-alpha.1
+
+### v0.16.1
+
+All changes since v0.16.0:
+
+**🐛 Fixes**
+
+- 🧊 **Git panel freeze + restart loop** ([#376](https://github.com/omdsh-dev/DSH-better-sidebar/pull/376), fixes [#369](https://github.com/omdsh-dev/DSH-better-sidebar/issues/369)): opening the Source Control panel could freeze the whole page, and the frozen layout restored itself after every reload with no way out — three unbounded layers compounding, now all bounded: **① status truncation** — the `git status --untracked-files=all` response is capped at 2,000 entries (capped results carry `truncated` and the panel shows a notice, mirroring `fs.read`'s truncation semantics; worktree change counts inherit the bound), so a huge untracked set can no longer freeze the browser main thread; **② bounded repository discovery** — a non-repository cwd (e.g. the home directory) no longer probes every visible child directory serially without limit: probe timeout 30s→5s, at most 200 probed directories, concurrent requests share one in-flight scan plus a 60s TTL cache, ending the `git rev-parse` spawn storm under `~`; **③ reset escape hatch** — loading with `?dsh-sidebar-reset` drops the persisted layout (shared width included) and starts from the default, breaking the loop even when the page is already hung; persisting resumes once the param is gone; `statusTruncated` copy synced across all 19 dictionaries
+
+### v0.16.0
+
+All changes since v0.15.2:
+
+**✨ New features**
+
+- 🪟 **Free windows** ([#354](https://github.com/omdsh-dev/DSH-better-sidebar/pull/354)): drag any tab (built-in or plugin-registered) out of the tab bar **onto the main conversation area** — a dashed drop hint marks the landing zone and release turns it into a floating window (default 390×780, phone-portrait ratio, clamped to the viewport and centered at the drop point). Windows can be moved by dragging the header, resized from the SE corner (≥320×200), raised to the top by clicking anywhere, sent back with the header context menu ("Back to sidebar" / "Close"), and closed with X through the normal `closeTab` lifecycle (pty release etc.). Dragging over a sidebar pane highlights it and releasing **docks** the window back into that pane. `floats` persist per session (restored as-is after refresh, lenient sanitize + geometry clamping). Service semantics: `features` gains `'floatWindows'` — `openTab`'s dedupe/id focus on a floating tab **raises its window** (no duplicate open, no panel expansion), `closeTab` / `activateTab` work on floating tabs and still fire their lifecycle callbacks, `visible` is always true inside a float, and agent-terminal reconcile covers floating windows. Tab content reuses the regular render path; plugin tabs are fully supported. Also ships the 8px-grid spacing cleanup of file sub-pages ([design](docs/plans/2026-08-23-free-window-design.md))
+- 📂 **Model-driven sidebar opens (`sidebar_open` tool)** ([#353](https://github.com/omdsh-dev/DSH-better-sidebar/pull/353)): a new global setting `agentOpenTools` (**off by default**) injects **one** tool letting the model open local **files** (editor tab, deduped by path), **folders** (full-window tree rooted there, `meta.dir`) and **HTTP(S) pages** (browser tab, URL prefilled) in the caller's sidebar. Turning the setting off unregisters the tool and clears the undelivered queue; already-open tabs stay. Opens targeting non-active sessions queue and replay when visible (`/sidebar/ws/agent-opens` push, same trust fence). No new public API and no new `/sidebar/api` routes ([design](docs/plans/2026-08-23-agent-open-tools-design.md))
+- 📝 **README-level inline HTML + table of contents (TOC) in Markdown previews** ([#360](https://github.com/omdsh-dev/DSH-better-sidebar/pull/360)): previews now genuinely render **block-level inline HTML** — badge walls `<div align=center>`, `<details>` blocks nesting markdown, `<br/>`/`<sub>`/`<img>` inside table cells, `<video>`/`<picture>` — all sanitized through a DOMPurify allowlist (`<script>` and other active content stripped, `<a>` forced `_blank rel=noopener`), with local media `src` rewritten to the session media route. With ≥3 headings a floating **TOC** button appears: smooth scroll, auto-expanding folded `<details>` ancestors, collecting headings from HTML segments too. The renderer is still the host `MarkdownText` (shiki / KaTeX / GFM preserved); pure-markdown documents take the original path with zero regression ([design](docs/plans/2026-08-24-markdown-html-toc-design.md))
+- 🌏 **Third-language coverage (19 languages)** ([#339](https://github.com/omdsh-dev/DSH-better-sidebar/pull/339)): optional peer `@huanlin/dsh-plugin-better-locale` adds full dictionaries for ja / de / fr / pt / ko / ar / hi / id / tr / vi / th / ru / it / nl / sv / pl / zh-HK / zh-TW / zh-MO (~340 keys each). Coverage **borrows the DSH English slot**: it is active only while DSH's active locale is `en` and is completely inert under `zh` (no mixed-language UI). The 19 dictionaries are also registered into better-locale so external `ctx.locale.lookup('betterSidebar', key)` callers get the override text. Without better-locale installed `ctx.get('betterLocale')` is undefined and the whole block is a no-op — zh/en behavior is unchanged
+- 🌿 **Multi-repository Git selection + linked-worktree discovery** ([#326](https://github.com/omdsh-dev/DSH-better-sidebar/pull/326) [#285](https://github.com/omdsh-dev/DSH-better-sidebar/pull/285)): when the session cwd is a workspace container rather than a Git repository, the Git panel discovers direct child repositories and shows a **repository selector** — status / branch / history / diff / stage / commit / revert / cherry-pick / file opening are all threaded through the selected repository. Linked-worktree change discovery and per-worktree git operations are transactionally bound to the selected checkout (including delayed pagination responses), stale/prunable worktree targets are rejected, and individual inventory failures degrade safely
+- 🖥️ **Browser loopback allowlist** ([#365](https://github.com/omdsh-dev/DSH-better-sidebar/pull/365)): a new side-card setting `browserAllowedLoopback` (comma-separated host or host:port entries; bare hosts match every port, host:port matches exactly) lets the sidebar browser navigate to explicitly trusted local addresses. Allowlisted loopback pages additionally get the `allow-same-origin` iframe sandbox token — local dev servers (Vite etc.) need a real origin for their module/HMR/fetch pipeline and would otherwise render blank. The page stays cross-origin to the GUI and to every other site; the server-side `browser.probe` route mirrors the same allowlist
+- 📝 **Vue + 28 legacy languages in the editor** ([#202](https://github.com/omdsh-dev/DSH-better-sidebar/pull/202)): `.vue` maps to `@codemirror/lang-vue` (template / script / style dispatch on the `lang` attribute, `<style lang="scss">` preprocessors); zero new dependencies bring scss/sass/less/stylus/ruby/lua/perl/r/dart/scala/groovy/powershell/diff/protobuf/cmake/pug/tcl/haskell/clojure/erlang/julia/pascal/vb/vhdl/stex/objectivecpp via legacy-modes. A throwing language factory degrades to plain text (console.warn) instead of breaking the editor; ambiguous `.v` / `.m` extensions stay unmapped on purpose
+- 🔄 **Editor preview refresh trio** ([#215](https://github.com/omdsh-dev/DSH-better-sidebar/pull/215) [#228](https://github.com/omdsh-dev/DSH-better-sidebar/pull/228), fixes [#167](https://github.com/omdsh-dev/DSH-better-sidebar/issues/167)): a **manual refresh** button for text previews; switching back to preview after an edit-save auto-reloads (suppressed while dirty so drafts survive); a successful save while in preview mode reloads on the saved edge. Automatic polling and the `fs.stat` version endpoint are gone (zero background API traffic)
+- 🖼️ **Local / relative images in Markdown** ([#292](https://github.com/omdsh-dev/DSH-better-sidebar/pull/292)): `![alt](./img.png)`, `/cwd/img.png` and reference-style `[id]: url` destinations are rewritten to `/sidebar/file` media URLs (still bounded by the session cwd) — previews no longer show just the alt text
+- ➕ **New recommended-catalog entry: ego-browser** ([#340](https://github.com/omdsh-dev/DSH-better-sidebar/pull/340)): `@dsh-external/ego-browser` Agent browser tab (registers a sidebar page automatically when better-sidebar is present, falls back to a floating bubble otherwise); description dictionary completed across 19 languages ([#371](https://github.com/omdsh-dev/DSH-better-sidebar/pull/371))
+
+**🐛 Fixes**
+
+- 🛒 **DSH marketplace managed-install compatibility** ([#338](https://github.com/omdsh-dev/DSH-better-sidebar/pull/338)): the public `cordis` entry was removed from `peerDependencies` (the market preview hard-rejects `cordis` in any dependency field — optional does not help), so the npm package satisfies the [dsh-community-market install rules](https://github.com/anywhere-labs/deepseek-harness-desktop/blob/master/dsh-community-market/docs/install-and-uninstall.zh.md) — catalog sources (dshfind / 1024Store) can re-issue the `repository_backlink` verified target and the plugin becomes installable through the Desktop market
+- 🔤 **Type base migrated to `@deepseek-ai/cordis`** ([#338](https://github.com/omdsh-dev/DSH-better-sidebar/pull/338)): the declaration surface (`src/context-types.ts`) no longer depends on or restates the public `cordis` — `Context` is now an **intersection** of the real vendored cordis Context with the structural service faces, and the `ctx.betterSidebar` type merge lives on `@deepseek-ai/cordis`. **Consumer migration**: change `import type { Context } from 'cordis'` to `import type { Context } from '@deepseek-ai/cordis'` (the `import type {} from 'dsh-better-sidebar'` merge path is unchanged); plugins that never used that import are unaffected
+- 🧩 **All internal `ctx.betterSidebar` reads fixed** ([#357](https://github.com/omdsh-dev/DSH-better-sidebar/pull/357), fixes [#356](https://github.com/omdsh-dev/DSH-better-sidebar/issues/356)): on npm-installed DSH 0.1.1-rc.x (web bundle) the sidebar died on every page load (`cannot get property "betterSidebar" without inject`) — the 26 internal direct reads now go through `ctx.get('betterSidebar')` (root reflect-store resolution, immune to the fiber chain); external consumers keep `inject: ['betterSidebar'] + ctx.betterSidebar`
+- 🔐 **Session-workspace boundary for file APIs** ([#345](https://github.com/omdsh-dev/DSH-better-sidebar/pull/345), fixes [#328](https://github.com/omdsh-dev/DSH-better-sidebar/issues/328)): fixed `fs.tree / fs.read / fs.write` workspace escapes; media, HTML preview and uploads share real-path symlink validation; regression tests for absolute paths, symlinks, uploads and nested Git sessions
+- 🪟 **Panel-host layering and viewport clipping** ([#330](https://github.com/omdsh-dev/DSH-better-sidebar/pull/330) [#278](https://github.com/omdsh-dev/DSH-better-sidebar/pull/278), fixes [#277](https://github.com/omdsh-dev/DSH-better-sidebar/issues/277)): panel host z-index 40→25 — below the DSH cordis dynamic-plugin layer (30), so the workbench no longer covers cordis inventory/approval surfaces (still above AppFrame's 20 and below the 100+ float stack); `overflow: hidden` on the host clips at the viewport edge, so collapsed panels no longer stretch the document into bidirectional scrolling (measured `scrollWidth` 2289→1672 / `scrollHeight` 1280→1032, any skin)
+- 📐 **Layout-push hardening** ([#310](https://github.com/omdsh-dev/DSH-better-sidebar/pull/310) [#130](https://github.com/omdsh-dev/DSH-better-sidebar/pull/130) [#180](https://github.com/omdsh-dev/DSH-better-sidebar/pull/180)): conversation column gets `min-height: 0` + `overflow: hidden` + `overflow-wrap: anywhere` (long unbreakable URLs / OAuth links no longer push the composer and left-rail Settings out of the viewport); the layout-push effect is split into "set only" + "remove only on unmount" and the width push is gated on `panelOpen` — dragging the bottom height with the right panel closed no longer squeezes the conversation, and release no longer flashes full-width; `useLayoutEffect` removes cross-paint full-width frames; all three drags flush the final frame and sync `centerRect.right` before committing; bottom height caps at `viewportHeight - PANEL_MIN`; drag handles no longer highlight mid-drag
+- 📱 **Mobile: unavailable-sidebar clarity + 1px overflow** ([#254](https://github.com/omdsh-dev/DSH-better-sidebar/pull/254)): with no session the toggle uses `aria-disabled` — keeping the non-executable semantics while allowing touch/keyboard focus so the "select a session to use the sidebar" tooltip is reachable; the panel uses `border-box` so mobile `100vw` includes the left border and no longer causes 1px horizontal overflow
+- 📏 **Side-card width shared across sessions** ([#36](https://github.com/omdsh-dev/DSH-better-sidebar/pull/36)): panel width is a layout preference, not session content — "last drag wins" writes the global `dsh-sidebar:v1:width` key that fresh and cached session switches adopt; without a global key (first run / pre-existing sessions) behavior is byte-for-byte unchanged
+- 🧹 **Terminals close immediately on session delete** ([#130](https://github.com/omdsh-dev/DSH-better-sidebar/pull/130)): new `PtyManager.closeSession()` subscribing to DSH's `session/disposed` — deleted sessions no longer wait for the 30s reconnect grace to release their terminals (agent terminals are agent-lifecycle-owned and untouched)
+- 🔍 **Filename search skips noise directories** ([#342](https://github.com/omdsh-dev/DSH-better-sidebar/pull/342)): `node_modules` / `.pnpm-store` / `.yarn` / `.turbo` / `.next` / `dist` / `build` / `coverage` etc. (case-insensitive, `.git` still skipped) — huge dependency trees no longer burn the 100k visit budget and return `truncated` early, so real files in later directories (`docs/`) are found; no `.gitignore` semantics, still filename lookup
+- 📝 **Mermaid global error rendering suppressed** ([#341](https://github.com/omdsh-dev/DSH-better-sidebar/pull/341)): `suppressErrorRendering` enabled — invalid diagrams no longer inject a large error SVG into `document.body`; the component-level error fallback and source display remain
+- 🖥️ **Terminal Nerd Font icon fallback** ([#190](https://github.com/omdsh-dev/DSH-better-sidebar/pull/190)): supplementary-plane PUA icons in starship / powerlevel10k prompts (Nerd Fonts v3 Material icon set) no longer render as tofu — `withIconFontFallbacks()` appends Nerd Font icon families to the winning base font (before the first generic family, deduped by family name, CSS global keywords filtered, no color-emoji fonts)
+- 🌐 **HTML preview declares UTF-8** ([#193](https://github.com/omdsh-dev/DSH-better-sidebar/pull/193), fixes [#170](https://github.com/omdsh-dev/DSH-better-sidebar/issues/170)): `/sidebar/html` responses carry `charset=utf-8` (Chinese fragments without `<meta charset>` no longer mojibake); original file bytes preserved
+- 🧪 **trust-fence Origin compared by hostname** ([#182](https://github.com/omdsh-dev/DSH-better-sidebar/pull/182)): some Chromium builds (Edge 151) serialize the Origin of non-default-port loopback pages without the port — `http://127.0.0.1` against `Host: 127.0.0.1:3080` no longer 403s (mirrors DSH's official gateway fence); different hostnames and opaque null origins are still rejected
+- 🪟 **"Show in folder" now reveals in the explorer** ([#94](https://github.com/omdsh-dev/DSH-better-sidebar/pull/94)): the folder-reveal gesture no longer opens the directory as a file in the editor (`"..." is a directory`) — `revealInExplorer` switches to the explorer tab, auto-expands a collapsed panel, expands the parent folder and highlights/scrolls to the produced file; the produced-files selector now reads the engine's Turn deliverables (same source as ui-deliverables)
+- 🖱️ **Panel-drag layout flash fixed** ([#180](https://github.com/omdsh-dev/DSH-better-sidebar/pull/180)): dragging the bottom height with the right panel closed no longer shifts the conversation left; release no longer flashes full-width before snapping back
+- 🖥️ **PowerShell installer fixes** ([#47](https://github.com/omdsh-dev/DSH-better-sidebar/pull/47)): the remote entry is now "download the script → strip the UTF-8 BOM → run it in memory", so `-Version` / `-DryRun` work again under Windows PowerShell 5.1 (the BOM no longer eats the leading `param(...)`); `pnpm --version` is checked before touching the profile (major <10 fails with a clear error and exit code 1)
+- 🔄 **Browser embed probing GET fallback** ([#69](https://github.com/omdsh-dev/DSH-better-sidebar/pull/69)): when a HEAD response omits both `Content-Security-Policy` and `X-Frame-Options`, probe retries once with GET — sites like Alibaba Bailian that only advertise their embed policy on GET no longer show a misleading "refused to connect"; they get the friendly "site refuses embedding" panel with an "open in browser" button
+- 🔧 **git-source installs fixed via `unrun` devDependency** ([#336](https://github.com/omdsh-dev/DSH-better-sidebar/pull/336)): tsdown 0.22 loads its config through `unrun` and pnpm 11 does not auto-install peer deps — git-hosted `prepare` no longer fails with `Failed to import module "unrun"` (npm tarballs unaffected)
+- 🍃 **Strict `ctx.effect` also fixed 4 latent sites**: interception / IME-guard effect bodies returned `undefined` on failure instead of a disposer (invalid shape under the vendored cordis effect contract) — now a no-op disposer

+<details>
+<summary><b>Older releases (v0.12.0 – v0.15.2)</b></summary>
+
+### v0.15.2
+
+All changes since v0.15.1:
+
+**✨ New features**
+
+- 🗂️ **"Open in app" submenu in the file tree** ([#334](https://github.com/omdsh-dev/DSH-better-sidebar/pull/334)): the file-tree context menu gains an "Open in app >" submenu — built-in openers (reveal/select in file manager, VS Code, Cursor, Zed), each with a pin button that promotes it to a top-level context-menu item (click again to unpin); with an optional SSH host configured, VSCode-family entries switch to the `vscode-remote/ssh-remote+<host>/<path>` protocol and local-only entries hide automatically; custom editors supported (name + URL template with `{path}` + "VSCode-family" flag, configured in the Files card gear popup). Open actions go through the new host route `POST /sidebar/api/open.external` (argv-array spawn, no shell injection) ([design](docs/plans/2026-08-22-open-with-menu-design.md))
+- 📑 **Tab context menu** ([#331](https://github.com/omdsh-dev/DSH-better-sidebar/pull/331)): right-clicking a tab offers **Close / Close others / Close to the left / Close to the right**, scoped to the current pane (tab group); items grey out when there is nothing to close; the menu only opens — it never switches the active tab; bulk closes go through the existing per-tab `onClose` path so lifecycle callbacks, pty release and agent-terminal shutdown all stay intact
+- 📄 **Diff files collapsed by default** ([#270](https://github.com/omdsh-dev/DSH-better-sidebar/pull/270)): each changed-file header is now an accessible expand/collapse control; recognized source files expand by default while tests, docs, generated files, lockfiles and unknown types stay collapsed; the existing 500-row cap for expanded content is preserved
+- 📖 **README update**: feature tour converted to a table (two screenshots per row, saves space); community section now shows the WeChat group and QQ group QR codes ([#325](https://github.com/omdsh-dev/DSH-better-sidebar/pull/325), QQ group 577011007)
+
+**🐛 Fixes**
+
+- 🪟 **Prune empty restored panes** ([#268](https://github.com/omdsh-dev/DSH-better-sidebar/pull/268)): persisted split panes left empty when ephemeral diff tabs were dropped no longer survive as full-size blanks — `sanitizeState` now also prunes the empty split leaf and repairs the stale active-pane pointer; a fully empty workbench keeps its single empty pane
+- 🖥️ **Hide spawned git windows on Windows** ([#301](https://github.com/omdsh-dev/DSH-better-sidebar/pull/301), fixes [#124](https://github.com/omdsh-dev/DSH-better-sidebar/issues/124)): the shared `runGit()` spawn options now set `windowsHide: true`, so repo-status polling and git actions no longer flash console windows on Windows (no behavior change on other platforms)
+- 📁 **Untracked files inside new folders** ([#242](https://github.com/omdsh-dev/DSH-better-sidebar/pull/242)): `git status` switched from `--untracked-files=normal` to `--untracked-files=all` — each file inside a new folder now shows as its own row and its diff can be loaded (no more `fs.read` "is a directory" error), matching VSCode's default behavior
+- ⚡ **Per-frame React re-renders eliminated for toggles/drags** (closes [#315](https://github.com/omdsh-dev/DSH-better-sidebar/issues/315)): `centerRect` moved to a ref with direct DOM writes to the bottom bar (zero React renders); `TabContent` memoized with an explicit comparator; a new frame-batcher coalesces Divider/dock drags per frame; meaningless locate passes skipped during drags. 4x CPU-throttled A/B: >17ms frames on toggle collapse 19→6 / expand 24→4~6, p95 21ms→15ms; drags unchanged (non-regression)
+
+### v0.15.1
+
+All changes since v0.15.0:
+
+**✨ New features**
+
+- 💬 **Codex-style transcript rework for Side Chat** ([#314](https://github.com/omdsh-dev/DSH-better-sidebar/pull/314)): transcript rows became **collapsible** — tool calls, thinking and context injections share one quiet single-line chrome (chevron + label + one-line argument summary) that expands into an indented body on a hairline thread, no cards or fills; streaming labels and a creating hero shimmer (shimmer = generating), failed tools go danger, `prefers-reduced-motion` stills every loop; **the first question is no longer swallowed by the boundary prompt** — context injection and first contact are delivered as separate events (boundary + parked snapshot ride `agent.inject`, the question wakes the driver), so the transcript maps injections onto a collapsible injection row while genuine user messages — the first one included — render as user bubbles; legacy threads' first message is split out into its own bubble too
+- 📖 **README rewrite**: feature tour (real UI screenshots per feature), user-facing DSH compatibility badges, simplified install (`add` → `approve-builds` → `add`, node-pty-safe build, paste-to-DSH install prompt), 28+ plugin ecosystem with per-category collapsed listings
+
+**🐛 Fixes**
+
+- 🖥️ **Terminal pty stays alive across conversation switches** ([#323](https://github.com/omdsh-dev/DSH-better-sidebar/pull/323)): switching sessions is no longer treated as a transient drop — the client sends a `park` control frame on unmount and the host skips the 30s reconnect-grace countdown; switching back (`open()` cancels parked) or explicitly closing the tab resumes the normal lifecycle; agent terminals keep their indefinite lifetime
+- 📂 **File-tree upload overlay no longer intercepts Tab drags** ([#317](https://github.com/omdsh-dev/DSH-better-sidebar/pull/317)): dragging tabs (reorder / cross-pane split) across the explorer no longer shows the upload overlay or swallows the event — gated on `dataTransfer.types` containing `Files` (consistent with the panel-host shield), so tabs land normally; OS file drags behave as before
+- 💬 **Subagent auto-open debounced** ([#314](https://github.com/omdsh-dev/DSH-better-sidebar/pull/314)): Side Chat thread creation no longer pops the task page — the 0→N trigger rearms for 500ms and re-evaluates the original baseline against the live snapshot, by which time the title filter recognizes the thread; genuine subagents still auto-activate the Tasks page (wide viewports expand the sidebar, while narrow viewports prepare the tab without forcing the drawer open)
+
+### v0.15.0
+
+All changes since v0.14.0:
+
+**✨ New features**
+
+- 💬 **Side Chat (beta) tab** ([#286](https://github.com/omdsh-dev/DSH-better-sidebar/pull/286)): Codex-style side threads, **one independent tab per conversation** — the child inherits the parent's full context (completed turns + pending messages + the in-progress turn's assistant output and tool activity, honestly frozen with an "interrupted" marker); created with an identical composition (same preset / provider / model) so the first request reuses the parent's input prefix cache; threads stay invisible in the main session list with zero subagent-catalog noise; follow-ups survive DSH restarts (auto cold-resume); one-click "Save as new session" promotes the thread to a top-level session ([design](docs/plans/2026-08-20-sidechat-tab-design.md))
+- 📤 **Upload into the files window** ([#239](https://github.com/omdsh-dev/DSH-better-sidebar/pull/239)): header "upload file / upload folder" buttons plus drag-drop (drop on the tree body = workspace root, on a directory row = that directory, on a file row = its parent directory, VSCode semantics); full-window blurred progress overlay while uploading (per-file progress + cancel / Esc); buttons disabled while busy, tree refreshes after the upload settles
+- 🧩 **Desktop compatibility in four options** ([#284](https://github.com/omdsh-dev/DSH-better-sidebar/pull/284)): "Position compatibility mode" is now a main-row dropdown — **Auto-detect** (default, conservative: only the standard Window Controls Overlay geometry contributes; real 32/36px caption-overlay heights per shell, live on maximize/restore; zero modification on plain web) / **DSH official web** (explicitly no adaptation) / **Shell preset** (built-in, opt-in; only shells that appeared in this repo's issues/PRs with 100+ stars, "detected" badge when the environment matches) / **Custom** (free-form CSS + shift distance). Documents that already carried compatibility values migrate to the custom scheme; interactive chrome opts out of desktop drag regions (`no-drag`); the bottom-push anchor is a composite selector (`[data-pane]` and `:has(> [data-slot])`)
+- 🎛️ **Settings page UI/UX modernization** ([#300](https://github.com/omdsh-dev/DSH-better-sidebar/pull/300)): the side-card secondary-settings entry is now a full-width "Feature settings" strip at the card bottom (replacing the invisible corner gear — much easier to discover); coordinated two-tone enabled state (brand activation accent + success-green check badge); every color is still `--dsw-alias-*` token-derived so skins follow automatically
+- ➕ **New entries in the recommended-plugin catalog**: `dsh-docs-panel` (global docs, [#230](https://github.com/omdsh-dev/DSH-better-sidebar/pull/230)), `dsh-flowglass` ([#261](https://github.com/omdsh-dev/DSH-better-sidebar/pull/261)), `dsh-git-forge` and `dsh-ssh-tunnel` ([#204](https://github.com/omdsh-dev/DSH-better-sidebar/pull/204)), `dsh-turn-review` ([#102](https://github.com/omdsh-dev/DSH-better-sidebar/pull/102))
+
+**🐛 Fixes**
+
+- ⚡ **Batched live preview for the subagent page** ([#298](https://github.com/omdsh-dev/DSH-better-sidebar/pull/298)): the old implementation polled `subagents.history` per running subagent, each poll triggering a full host-side enumeration — an O(N²) amplification that stalled the page with many concurrent subagents; now a single batch route `subagents.live` (one enumeration of the whole tree) plus one client poller with a single in-flight request; display logic and copy unchanged
+- 🖱️ **Interrupted / fast-release drags no longer roll back** ([#249](https://github.com/omdsh-dev/DSH-better-sidebar/pull/249), closes [#247](https://github.com/omdsh-dev/DSH-better-sidebar/issues/247) [#248](https://github.com/omdsh-dev/DSH-better-sidebar/issues/248)): interrupted or fast-released drags commit the last known position; HMR re-activation re-locates the center column (fixes the blank bottom panel after a hot reload)
+- 📐 **Push variables stay effective while mounted** ([#259](https://github.com/omdsh-dev/DSH-better-sidebar/pull/259), fixes [#258](https://github.com/omdsh-dev/DSH-better-sidebar/issues/258)): the bottom panel no longer flashes full-width after a drag is released
+- 🔐 **Workspace boundary hardening for file APIs** ([#328](https://github.com/omdsh-dev/DSH-better-sidebar/issues/328)): `fs.tree/read/write`, media, HTML preview, and uploads now share real-path containment checks that reject outside absolute paths and symlink escapes
+- 🔧 **Adapted to DSH 0.1.1-rc.1 / rc.2 (@next)** ([#297](https://github.com/omdsh-dev/DSH-better-sidebar/pull/297) [#305](https://github.com/omdsh-dev/DSH-better-sidebar/pull/305)): no code changes needed
+- 🔒 **Upload-chain hardening** ([#239](https://github.com/omdsh-dev/DSH-better-sidebar/pull/239)): empty and absolute `relativePath` segments are refused outright; uniquely named temp files (concurrent uploads stay independent, crashed processes never block later uploads); write-stream error listeners (a failing disk can no longer crash the host); client error codes unified with the wire (`too-large`), 413s localized
+
+### v0.14.0
+
+> ⚠️ This release requires DSH ≥ 0.1.0-rc.8. All changes since v0.13.1:
+
+**✨ New features**
+
+- 🖼️ **Unified panel-host injection refactor** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): panels/toggle clusters moved into a `[data-dsh-panel-host]` fixed containing block (`fixed inset-0 z-40`), immune to desktop-shell intermediate transforms hijacking `fixed`; mount self-check (page-level transform → `data-dsh-panel-host-degraded` degraded sync, judged on uncorrected geometry, exits only when the ancestor transform is gone); push anchor switched to `#root [data-dsh-frame] > [data-pane="conversation"]` + `#root` calc width against desktop-shell additive overflow; chunk revalidation on activation (HEAD+ETag keeps unchanged chunks, 5s timeout fails open); `visualViewport` keyboard inset + `env(safe-area-inset-*)` mobile adaptation
+- 📂 **Separate file windows by default** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): `editorExplorer` now defaults to **separate** — tree clicks / file opens create a new tab per path and the path-less window is a pure file manager; merged mode stays available as an opt-in
+- 🖥️ **Terminal shell / shellArgs configurable from the settings page** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): the terminal card's gear popup gains "Shell path" and "Shell arguments" rows (previously yaml-only via `cordis.patch.yml`) — saved values take effect immediately for terminals opened afterwards (UI terminals and model `terminal_create` alike); empty keeps the existing yaml → `$SHELL` / login shell / `powershell.exe` resolution order
+- 🏷️ **Version badge on the settings page** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): the side-card settings section now opens with a `DSH-better-sidebar v0.14.0` identity badge (version synced with the service instance, test-guarded)
+- 🔍 **Add-plugin catalog: search / grouping / independent scroll** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): built for a growing plugin ecosystem — a live search box (filters by name / id / description), optional `category` grouping for entries, and an independently scrolling list (the modal no longer grows unbounded with catalog size)
+
+**🐛 Fixes**
+
+- 🧩 **rc.8 module-system migration** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): rc.8 no longer exposes the `window.__DSH_MODULES__` page global (it moved to the `ctx.modules` service), which broke every lazy chunk's externals resolution — the client now injects the `modules` service and shares it with chunk-bundle copies through a plugin-owned global (terminal / editor / Mermaid on-demand loading restored)
+- 🧩 **Chunk revalidation barrier hardening** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): HEAD revalidation gains a 5s timeout (fails open on a stuck route so the barrier can never wedge lazy loads); `resetChunks` clears a pending revalidation barrier
+- 🖱️ **Drag robustness** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): fast releases (browsers merge/lose pointermove bursts) commit the last known dragged position instead of rolling back; `pointercancel` / lost-capture interruptions keep the drag result too; the center column is re-measured right after commit (no mid-frame bottom-panel width jump); HMR re-activation re-locates the center column via an `<html>` style observer plus a retry when the bottom panel opens (fixes the blank bottom panel / shifted input bar after a hot reload)
+
+### v0.13.1
+
+**✨ New features**
+
+- 📊 **Safe Mermaid rendering in the Markdown preview** ([#164](https://github.com/omdsh-dev/DSH-better-sidebar/pull/164)): when a previewed md file contains mermaid fences, a `client-mermaid.js` chunk (~7MB) is served on demand (zero load without mermaid); defense-in-depth rendering — `securityLevel: 'strict'` + `htmlLabels: false` (node labels use real SVG `<text>`) + a second sanitize pass before SVG injection (foreignObject/script/foreign HTML elements removed, `@*`/`on*`/`href` attributes stripped); click a diagram to zoom in a modal overlay (wheel zoom centered on the cursor, drag pan, toolbar & shortcuts), re-renders with light/dark theme, falls back to the raw code block on parse failure
+- 🖥️ **Configurable terminal shell & shellArgs** ([#125](https://github.com/omdsh-dev/DSH-better-sidebar/pull/125)): `cordis.patch.yml` `better-sidebar.config` can set `shell` / `shellArgs` (a non-empty `shellArgs` fully replaces the defaults; unset keeps the previous auto-resolution of `$SHELL` / login shell / `powershell.exe`), applied to both UI terminals and agent terminals (`terminal_create`); terminal tab titles now show the shell name (bash/zsh/powershell) and internal tab ids use UUIDs so the same shell can open multiple terminals
+
+**🐛 Fixes**
+
+- 🔗 **Aggregate double-mount auto-yield** ([#200](https://github.com/omdsh-dev/DSH-better-sidebar/pull/200)): when an aggregate package (e.g. dsh-web-ui-all) mounts the same package under its own entry id, the guard expression in `cordis.patch.yml` disables the plugin's own `better-sidebar` row so `/sidebar/api` is no longer registered twice (`duplicate prefix route` crashing the whole plugin tree / `dsh web`); standalone installs behave as before
+- 🔧 **Adapted to DSH 0.1.0-rc.7** ([#207](https://github.com/omdsh-dev/DSH-better-sidebar/pull/207), fixes [#206](https://github.com/omdsh-dev/DSH-better-sidebar/issues/206)): fixes the `agent-presets: refusing to compose an unscoped context` error when picking a model / sending a message after DSH moved to rc.7
+
+### v0.13.0
+
+**✨ New features**
+
+- 📁 **Files window merged with the explorer** ([#151](https://github.com/omdsh-dev/DSH-better-sidebar/pull/151)): new `editorExplorer` setting (editor card gear) — file tabs gain a path-input header plus a toggleable right-docked file tree (per-tab open/width memory, drag-resize 160–480px from the left edge, global filename search via the host `fs.search` route with a hard budget, skipping `.git` and symlink dirs); in separate mode (default) tree clicks / Enter in the path input open each file **in its own new tab**, merged mode switches the current tab **in place**; fresh sessions seed an empty Files window instead of the explorer tab, and a path-less window is a bare file manager in separate mode / a chrome'd empty file window in merged mode; the tree context menu offers "Open in new tab" and "Open to the side" (split)
+- 🎛️ **Select rows for declarative settings** ([#151](https://github.com/omdsh-dev/DSH-better-sidebar/pull/151)): settings rows gain `type: 'select'` (`options` with value/title/desc/icon, `multi` stores the picked values as an array); options with icons render big-icon option cards and keep the icon in the closed anchor; `editorExplorer` became an iconed select (merged vs separate); the capability list gained `settingSelect`
+- 🔀 **Mutual exclusion with the dsh-web-ui family right panel** ([#181](https://github.com/omdsh-dev/DSH-better-sidebar/pull/181)): reads the `aionui-panel` settings namespace's provider choice — when "Use aionui-panel" is selected, the whole better-sidebar (right sidebar / bottom panel / floating entry / all takeovers) does not mount; with DSH-better-sidebar (or no aionui installed) it behaves as before. Takes effect live after a settings save (settings-document push), no reload needed
+
+### v0.12.3
+
+**✨ New features**
+
+- 🎨 **Skin compatibility (token-driven)**: fully consumes DSH design tokens and follows the dsh-web-ui skin center's 10 skins automatically; terminal/editor surfaces fall back to opaque backgrounds under transparent/translucent-glass token values so text never scrolls over the skin art ([#110](https://github.com/omdsh-dev/DSH-better-sidebar/pull/110), fixes #106 #105 #90 #60, also #52 #57 #92)
+- 🗂️ **Unified path handling**: UNC / symlink classification (directory symlinks expandable, broken links highlighted) + HTML-route platform guards ([#134](https://github.com/omdsh-dev/DSH-better-sidebar/pull/134), #65 #67 #43 #79 #115)
+- 🖥️ **Configurable terminal shell**: custom shell setting with Windows pwsh auto-probe ([#95](https://github.com/omdsh-dev/DSH-better-sidebar/pull/95))
+- 📝 **Editor languages**: C# / Kotlin / Swift syntax highlighting ([#120](https://github.com/omdsh-dev/DSH-better-sidebar/pull/120))
+- 🧭 **Settings nav icon**: settings-page navigation icon and layout polish ([#114](https://github.com/omdsh-dev/DSH-better-sidebar/pull/114))
+- ➕ **Recommended-plugin catalog**: added `dsh-git-remotes` — Git Remotes tab (branches/upstream/ahead-behind, fetch with prune, ff-only pull, confirm-before-push; does not replace the built-in stage/commit tab) ([#91](https://github.com/omdsh-dev/DSH-better-sidebar/pull/91)); and `dsh-video-preview` — inline video preview (.mp4/.webm/.mov/.mkv/.avi etc.) backed by a /video host route with HTTP Range (206) scrubbing, not capped by the 20MB mediaLimit ([#126](https://github.com/omdsh-dev/DSH-better-sidebar/pull/126))
+
+**🐛 Fixes**

 ## ✨ 功能一览
 
-- **🗂️ 文件工作台**：资源管理器（懒加载目录树，**展开的目录由宿主按目录 watch、改动后自动重列**；软链接按目标类型展示——目录软链接可展开、失效链接标红；文件树与文件 tab 按扩展名显示图标——markdown / 图片 / PDF / 代码 / 配置 / 压缩包等各有 glyph，插件可经 `registerFileIcon` 注册自定义图标与目录图标）+ **可编辑**的 CodeMirror 编辑器；Markdown（含 Mermaid 图表，strict 安全渲染 + 点击放大；README 级内嵌 HTML——徽章墙 / `<details>` 折叠 / 表格内联标签经 DOMPurify 消毒真实渲染；浮动目录大纲一键跳转）与 HTML（沙箱 iframe + 两个宿主没有的逃生门开关）仍由插件渲染
-- **🌐 浏览器与文档预览（由 DSH 内置提供）**：网页 tab 是宿主自己的 `ui-sidebar-browser`（多开 / 后退前进刷新 / 沙箱 iframe，**0.1.7 起只在 desktop profile 挂载**）；表格 / PDF / 图片 / Office 预览是宿主自己的 `ui-sidebar-documentpreview`（宿主侧 Office→PDF 转换、电子表格 worker 表格、图片 / PDF 缩放视口、按目录自动刷新）。插件**不再认领**这些格式，只保留宿主没有的那一半：**外链接管**——只认领有 tab 类型通过 `urlTarget` 明确声明的链接，其余一律放行给宿主（正文链接的去向由宿主用户设置 `linkOpening` 决定）
-- **💻 终端（DSH 内置）**：右侧栏终端由 **DSH 内置**的 `ui-sidebar-terminal` 提供（shell 选择 / 重命名 / 断线重连 / 刷新后恢复 / 主题跟随）。插件不再自带终端实现
-- **📂 模型侧边栏打开（可选）**：全局设置开启后注入 `sidebar_open` 工具——模型可主动在侧边栏打开文件 / 文件夹（树以该目录为根）/ HTTP(S) 网页（网页 tab 需要宿主提供 `browser` kind，即 desktop profile）
-- **🌿 文件变动**：Git 视角（真 diff / 历史 / 暂存·提交·还原 / worktree·子仓库选择）与本轮文件视角（模型读 / 写 / 编辑实时追踪，按文件分组、按类型筛选）**双视角合一**；统一 diff 渲染（改蓝配对 + 行内字符级高亮 + 语法着色（含 mjs/cjs/mts/cts、CSS/SCSS/Less、HTML/XML/SVG/Vue、GraphQL、JSONC/JSON5）+ 上下文折叠），底部可拖拽预览面板，可一键展开为独立 diff tab（落进工作台的 diff 分栏）；`.md` 操作（读 / 写 / 编辑）预览头部可切换**阅读模式**——经共享 MarkdownText 渲染 GFM 表格 / 任务列表 / 删除线 / 脚注 / 数学公式，本地图片自动改写为 `/sidebar/file` 媒体路由；含 ```mermaid 围栏时走编辑器同款懒加载 mermaid 渲染器（图可点击缩放 / 平移）；**敏感内容脱敏**——凭据形态路径整文件遮罩、普通文件按内容形态遮值（api_key: / Bearer / sk- / AKIA / ghp_ / PEM 等，字段名保留），默认开启、预览面板一键开关（localStorage 记忆），仅影响显示、不改会话数据。已知边界：mermaid 无引号节点标签含被遮密钥时，图回退源码（规避：标签加引号）；`.html` 操作（读 / 写 / 编辑）预览头部可切换**渲染模式**——复用编辑器同款 `/sidebar/html` 路由 iframe，相对资源（./style.css、img/x.png）同路由解析，分段读取也渲染完整文档，恒定沙箱（opaque origin + CSP 头，无逃生门）；`.pdf` 操作（读 / 写 / 编辑）同样可切换**渲染模式**——复用编辑器同款 PDF 预览（媒体路由字节流 + 显式 Blob，浏览器原生查看器内嵌，附下载入口）
-- **🧩 后台任务页**：subagent 拓扑 + 后台任务（退出码 / 实时输出 / 强制终止）
-- **💬 侧边对话(beta)**：Codex 风格的侧边线程——继承主会话完整上下文（含进行中的回合与工具调用）独立运行，不进入主会话；线程内可持续追问，一键「保存为新会话」提升为顶层会话
-- **🖥️ 原生右侧栏 + 底部工作台**：右列交给 DSH 原生右侧栏——插件把每个 tab 类型注册成原生 tab（文件打开走 `dsh-resource://file/**`，并接管内置「文件」页 / 文件树），插件自己只保留底部工作台（分栏 / 随会话持久化），开合按钮挂在会话头右侧
-- **🔁 会话隔离**：布局 / Tab / 面板按会话持久化，陈旧状态自动净化
-- **⚙️ 声明式设置**：设置页「侧边卡片」逐项独立开关，二级设置经齿轮弹窗
-- **⚡ 按需加载**：启动只拉 ~325KB 核心，编辑器 / Mermaid 图表 / 第三语言词典等重依赖用到才按需拉取（[设计文档](docs/plans/2026-08-12-lazy-chunks-design.md)）
-- **🌏 多语言**：界面文案跟随 DSH 语言（zh / en）实时切换；安装 `@huanlin/dsh-plugin-better-locale` 后支持日语（ja）等第三语言覆盖（见下方「🌏 第三语言覆盖」）
+相比 DSH 官方侧边栏，本插件补上的关键能力：
 
-> 🔌 **核心理念**：服务优先——内置的 5 tab + 3 viewer 与第三方插件通过同一套 `ctx.betterSidebar` API 注册，能力完全对等；官方不再内置、可由生态提供的功能，交由生态插件实现（已有 **28+ 生态插件**，见下方「🌐 插件生态」）。接入文档见「🔌 服务化扩展」与 [外部插件接入指南](./docs/external-plugin-guide.md)。
+- **🖥️ 可编辑的代码编辑器**：官方文档预览是**只读**的 → 插件保留**可编辑**的 CodeMirror 编辑器（保存、语法高亮、预览切换）；Markdown / HTML 也走插件自有渲染（Mermaid 图表安全渲染 + 点击放大、README 级内嵌 HTML、浮动目录大纲、HTML 沙箱预览）
+- **🗂️ 增强文件树**：接管内置「文件」页——懒加载目录树、**展开的目录实时 watch 自动刷新**、软链接识别、全局文件名搜索、拖拽上传、悬浮 `@文件` 一键引用进输入框
+- **🌿 文件变动**（官方侧栏没有 Git 面板）：Git 视角（diff / 历史 / 暂存·提交·还原）+ 本轮 AI 改动视角双合一，统一 diff 渲染（行内字符级高亮、语法着色、敏感内容脱敏）
+- **🧩 任务管理**（官方没有）：子代理拓扑实时预览 + 后台任务清单（退出码 / 实时输出 / 强制终止）
+- **💬 侧边对话**（官方没有，beta）：Codex 风格侧边线程——继承主会话完整上下文独立运行，可持续追问，一键提升为顶层会话
+- **🖥️ 底部工作台**（官方没有）：右列交给 DSH 原生右侧栏，插件另加自绘底部工作台（拖拽分栏 / 按会话持久化），可与原生栏同时展开
+- **📂 模型打开侧边栏（可选）**：`sidebar_open` 工具让模型主动在侧边栏打开文件 / 文件夹 / 网页
+- **🔌 服务化扩展**：`ctx.betterSidebar` 向所有插件开放（`registerTab` / `registerFileViewer`），内置 5 tab + 3 viewer 走同一套 API，已有 **28+ 生态插件**（见「🌐 插件生态」）
+- **⚡ 按需加载**：启动只拉 ~325KB 核心，编辑器 / Mermaid / 第三语言词典按需加载 · **🌏 多语言**跟随 DSH · **🔁 会话隔离**按会话持久化布局

+
+- 🗂️ **只读文件预览整体让给 DSH 的文档预览**：DSH 0.1.7 的 `ui-sidebar-documentpreview` 自带表格 / PDF / 图片 / Office 渲染（宿主侧 Office→PDF 转换、电子表格 worker 表格、图片 / PDF 缩放、按目录自动刷新），所以插件删掉了自己的 `image` / `pdf` / `binary-download` 三个 viewer，并在 `editor.canOpen` 里**拒绝认领**这些扩展名——`xlsx xls csv tsv fods pdf png jpg jpeg gif webp svg bmp ico doc docx ppt pptx`——把文件地址交回宿主。**rc.1 收回其中 9 个**：`xlsb` / `xlt` / `xltx` / `xltm` / `ots` / `dot` / `dotx` / `avif` / `ods` 宿主其实**没有渲染器**（点开只有「暂不支持预览」），而它们在让出之前是走插件兜底显示下载面板的，属于我们上一版自己引入的回归；现由插件的 `code` catch-all 重新认领。`fods` 继续让出（宿主会用纯文本显示这段扁平 XML，比下载面板有用）。**插件仍保留三件宿主没有的**：Markdown（自带渲染器）、HTML（自带沙箱预览 + `htmlViewerNoSandbox` / `htmlViewerDefaultUnsafe` 两个安全开关）、以及**可编辑**的文本 / 代码编辑器（内置那几个是只读预览）；未知二进制（`.zip` / `.wasm`）仍走代码编辑器判 binary 后的下载面板，功能不回归。

+- ⚙️ **设置接入面重写 + 用户偏好的自动回迁**：DSH 0.1.7 删除了插件可注册的设置命名空间，改为**按插件 Loader 行的 entry id 找表单**（`SettingsForms`：只剩 `describe` / `update` / `replace` / `mutate` / `configure`）。插件偏好因此落在 **profile 的 cordis patch 文档**里（即本插件的挂载行），不再是 `~/.dsh/settings.yaml`；schema 来自插件模块导出的 `Config`（本版把用户偏好并进 `Config`，并给每个偏好字段标 `meta.volatile = true`——**这一个标记就是「改设置实时生效、不重挂插件」的全部机制**）。**用户设置不会丢**：插件首次启动时会把旧 `settings.yaml` / `settings.yaml.imported` 里的 `dsh-better-sidebar` 段一次性回迁（只在该行还没有任何用户值时执行，且只迁移当前 schema 仍声明的字段）。entry id 是**运行时自发现**的（本包默认 `better-sidebar`，聚合包挂载时会是别的 id），不硬编码。
+- 🔄 **文件树实时刷新**：插件接管了内置「文件」页，宿主自己的按目录 watch 覆盖不到它——本版新增 `/sidebar/ws/fs-watch`：客户端上报**已展开**的目录，宿主按目录 `fs.watch`（150ms 去抖、每连接 64 个句柄上限、路径仍走 `fs.tree` 同一道 workspace fence），改动后只重列那一层、折叠即退订。此前文件树会一直陈旧到手动刷新。

+
+## 🛠️ 开发与构建
+
+```sh
+pnpm install      # @deepseek-ai/* devDependencies 已发布（基线 0.1.7-rc.1，alpha dist-tag），直接解析、无需令牌
+pnpm typecheck    # tsc --noEmit
+pnpm lint         # eslint .（flat config：js + typescript-eslint + react-hooks recommended）
+pnpm build        # → lib/index.js + lib/invariant.js + lib/client.js + lib/client-registry.js + lib/types
+pnpm test         # vitest（含 manifest 一致性守卫，需先 build）
+pnpm watch        # tsdown --watch
+```
+
+**Make 薄封装**（`make help` 查看全部目标；package.json 仍是唯一事实源）：
+
+```sh
+make check          # 聚合校验门禁：typecheck → build → test → check:consumer-types（对齐 CI）
+make mount          # 真机挂载冒烟：build + pack → 安装 Chromium → pnpm test:mount
+make clean          # 清理 lib/、*.tgz、playwright-report/、test-results/
+```
+
+`pnpm check:consumer-types`：对外类型声明面守卫——以浏览器-only 消费者（无 `@types/node`、`skipLibCheck: false`）的视角对构建出的 `lib/types` 做类型检查，需先 `pnpm build`。
+
+**架构**：单 npm 包、host/client 双半结构——host（`src/index.ts`）：`/sidebar/api/*` JSON API、`/sidebar/file` 媒体路由、`/sidebar/html` 预览路由、`/sidebar/upload` 上传路由，以及两条 WebSocket（`/sidebar/ws/agent-opens` 模型打开推送、`/sidebar/ws/fs-watch` 文件树目录 watch；fs / git / 预览全部会话级 + 信任围栏）；client（`src/client/index.tsx`）：portal 侧边栏 + 各视图 + 链接接管；状态按会话持久化 localStorage。插件按 DSH 官方规范组织（无 default 导出、双 client bundle），运行期不依赖 npm / checkout（`@deepseek-ai/*` 由 web profile 提供）。
+
+## 🔐 安全
+
+- 路由受 Host 头信任围栏保护（与 `/api` 一致）；`fs.write` 原子写入；媒体/预览路由仅限会话 cwd 内文件（`workspaceFence` 关掉时除外，见设置页）；git 只调 CLI、绝不设置身份
+- HTML 预览的内容在**不透明源沙箱 iframe** 中渲染（无 `allow-same-origin`/`allow-top-navigation`、`no-referrer`、权限策略全禁）；`/sidebar/html` 路由带 CSP `sandbox` + 大小/路径边界
+- 设置页可按功能关闭 HTML 预览的沙箱（`htmlViewerNoSandbox` / `htmlViewerDefaultUnsafe`，默认关闭，带警告文案）——关闭后内容与界面同源，仅建议对完全可信内容使用。**网页 tab 的沙箱不再是插件的面**：浏览器视图由宿主提供（desktop profile），其沙箱与导航策略见 DSH 侧文档
+
+## ⚠️ 已知限制
+
+- Git 无 push/pull/fetch；Markdown 预览提供手动刷新按钮，刷新未保存编辑前会确认是否丢弃草稿；文件树只对**已展开**的目录做 watch（折叠的目录不订阅，也不做全工作区递归扫描）；工具行内文件打开按钮不可拦截
+- **只读预览的格式由宿主决定**：表格 / PDF / 图片 / Office 走 DSH 自己的 `ui-sidebar-documentpreview`，插件只渲染 Markdown / HTML 与可编辑的文本代码；宿主的实现（渲染细节、缩放、刷新时机）随 DSH 版本走
+- **浏览器视图只在 desktop profile 存在**：Web profile 没有宿主 `browser` kind，插件也不再自带浏览器 tab，因此网页 tab 只在 desktop profile 可用；登录态 / 第三方 Cookie / `X-Frame-Options` 等限制随宿主实现
+- HTML 预览渲染的是已保存文件（不反映未保存草稿）
+- 移动端（<768px）无底部面板：进入窄屏时其标签页一次性并入右侧栏（迁移后回桌面仍保留在右侧栏），桌面端的底部面板只在宽视口下可用。未选中会话时，点按弱化开关会显示选择会话提示；选中会话后开关打开全宽抽屉
+
+## 🖥️ 平台支持
+
+Windows / Linux / macOS 三平台适配（macOS 日常验证；其余经单元测试覆盖）。插件不再包含原生依赖（终端与 `node-pty` 已整体交还 DSH 自身），构建只需 Node + pnpm，无需编译工具链。

-### v0.20.0（开发线，**从未发布**）
-
-> 🚫 **这一版没有发布到 npm**（npm 上 `latest` 仍是 v0.19.1）：它原本是 0.1.6-alpha.2 线的正式版，开发完成后被 0.21 线直接取代，所以下面这些变更实际随 **v0.21.1** 一起发布。原本的定位：仅支持 **DSH 0.1.6-alpha.2+**（peer 下限 `^0.1.6-alpha.2`，CI 钉 `@deepseek-ai/dsh@0.1.6-alpha.2`）。**这是一次破坏性变更版**：0.1.5-rc.* 用户请固定 `dsh-better-sidebar@0.19.1`。适配记录见 [docs/plans/2026-09-21-dsh-0.1.6-alpha.2-adaptation.md](docs/plans/2026-09-21-dsh-0.1.6-alpha.2-adaptation.md)。
-
-- 🖥️ **终端交给 DSH 内置**：DSH 0.1.6 自带右列终端（`ui-sidebar-terminal`），所以插件删掉了整套自研终端——`pty-manager` / `agent-pty` / `pty-deps` / 8 个 `terminal_*` 工具 / xterm 视图与字体链接 / 跨会话固定终端，以及 `node-pty` 依赖、它的 `allowBuilds` 放行与安装脚本的 `-Repair` 模式。**注意**：模型因而失去跨调用持久的终端（只剩一次性 `bash` / `pwsh`）；上游 `@deepseek-ai/dsh-tool-terminal` 未被内置 bundle 挂载，需要时请自行在 profile 里启用。
-- 🌐 **浏览器视图让给内置**：插件删掉 `BrowserView` / 沙箱状态条 / 嵌入性探测（含宿主 `browser.probe` 路由）与两个只配置自家 iframe 的设置项；**保留**聊天与界面的外链接管（按协议分流是宿主没有的能力），目标改为 DSH 内置的 `browser` tab 类型。
-- 🧩 **产物行交回宿主**：DSH 0.1.6 把 `conversation.chat.turnTail` 从 chain 改成 list（上游有意让多个插件**追加**而非互相替换），插件原来的接管只能与内置产物卡重复，因此整体删除；点击行为不变（内置走宿主 `openFile` → 本插件编辑器）。代价是失去轮尾那一个「在文件树中显示」入口（树内右键仍在）。
-- 🐛 **修复两个静默破坏**：`SidebarRightGuideEntry.id` 变成必填后，缺 id 会让**整个原生承载面静默空掉**（抛在 `ctx.inject` 回调里被吞）；`turnTail` 改 list 后原注册直接抛错、产物行失效。两处都已修好并加测试守护，同时补了注册失败的上报口。
-- 🎨 **空白面板卡片对齐内置卡风格**：`.paneCard` 改用 DSH 指南胶囊那套配方（0.5px l4 描边 / 24px 圆角 / layer-1 填充 / 56px 下限 / 14×20 内边距），并加测试守护其几何、令牌化配色，以及不复制上游那套**未定义**的 `--dsw-alias-bg-l1/-l2` 拼写。
-- 📐 **基线**：`@deepseek-ai/dsh-*` 全部钉 `0.1.6-alpha.2`，`dsh-code-runtime` 整包消失已移除，`diff` / `simple-icons` 作为 primitives 的新裸 import 提升进 devDependencies；`ui-primitives` 本版三处破坏（`IconSendOutline16` 下线、`TerminalBlockLabels.noExitCode` 新增、`ConnectionIndicator.reconnectLabel` 移除）同步适配。
-
-### v0.19.1
-
-> 📌 **正式版**（npm `latest`，无 prerelease 后缀）：钉版推进到 **DSH 0.1.5-rc.2**（npm `next`），**peer 下限仍是 `^0.1.5-rc.1`**——rc.2 的上游 delta 里没有任何触及本插件的面（零 `packages/api|host|session|agent` 变更，真实代码改动只有消息反馈弹窗、产物卡片 CSS 与 `CodeFileIcon` 的 SVG 数据拆分），因此 rc.1 用户无需升级 DSH 即可用本版。DSH 0.1.5-alpha.2 用户继续用 **v0.19.0-alpha.1**；0.1.2-rc.1 稳定线继续用 **v0.18.1**。
-
-- 🎯 **适配 DSH 0.1.5-rc.2**：devDependency 钉版、CI 挂载车道与 `SIDEBAR_SERVICE_VERSION` 同步到 rc.2；插件侧**零代码改动**（上游 delta 未触及本插件，逐文件核对见 [docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md](docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md)——300 个变更文件里绝大多数只是各包 `package.json` 的版本号单行）。
-- 🎨 **文件图标（#611）与内置 Tab 图标改为彩色**（#531 + #594 合并，实现按 rc.2 重做）：
-  - **文件/文件夹图标走 DSH 官方图形**：回退链末端是宿主 `ui-primitives` 的 `FileTypeIcon`（48 类官方全彩代码/配置图形 + markdown/图片/PDF/Office/视频/文件夹的类目色板），插件**不再自带扩展名表，也不再需要图标懒加载 chunk**——`#429` 那份 563 条彩色数据与 `lib/client-file-icons.js`（255 kB）连同 `fileIconTheme` 设置开关一并删除，彩色就是唯一形态（核心 bundle 因此只增 10 kB）。
-  - **新增对外 `registerFileIcon` API**（能力 `'fileIcons'`）：按扩展名（`exts`）、精确文件名（`names`）、目录名（`folderNames`）注册自己的图标，优先级降序、同级按注册序；**注意**：宿主分类器覆盖任意路径，所以注册 `exts: []` 的 catch-all 会接管所有未具体命中的行。
-  - **内置 tab 图标彩色**：文件 / 文件变动 / 任务管理 / 侧边对话 / 终端 / 浏览器 六个类型与 diff 视图的 glyph 换成彩色版本（颜色全部来自 `--dsw-alias-*` 令牌，皮肤照旧全覆盖）。
-  - **原生右侧栏的 tab 芯片也带图标**：宿主的 tab 定义没有 icon 字段，但 `sidebar.right.pane.tab.title` 槽就是芯片内容——插件在该槽渲染「图标 + 标题」（编辑器 tab 带路径时显示该文件的图标），glyph 为 `aria-hidden`，芯片可访问名不变。
-- 🛠 **CI 修复一：Windows lane 的真实超时**。`ci-windows` 在 2026-09-09/10 窗口内红了 8 次，其中 6 次是真起进程的用例撞上 vitest 默认 5000ms：`tests/agent-pty.spec.ts`（真起 PowerShell + ConPTY）与 `tests/install-powershell.spec.ts`（冷启 `powershell.exe` 实测 12.1s）现在各自声明 30s 预算，且 `vitest.config.ts` 的全局 `testTimeout` 从默认 5000ms 提到 **15s**（第一次真实 Windows 跑又在**第三个**文件上翻车：`tests/git.spec.ts:85` 耗时 9607ms——三个文件同一个根因，逐文件加超时是打地鼠）；`waitForTranscript` 的内层轮询预算从 5000ms 降到 15s，**内层预算必须小于外层**（原先是同一个 5000ms，结构性必然超时）。`ci-windows` 的 `Test` 改跑 `pnpm test:windows`（`--maxWorkers=2`），在 2 核 runner 上不再让真起进程的 spec 互相抢占。
-- 🛠 **CI 修复二：挂载车道的 npm 安装**。`plugin-mount` 的 `npm install -g @deepseek-ai/dsh@<ver>` 曾 4 次失败（2 次 `ETARGET`、2 次 `JavaScript heap out of memory` exit 134）：钉版自身的传递依赖是浮动 `^` 范围，上游**分阶段发布**预发布版时（rc.2 于 09-10 的 14:43–14:57 逐包上线）npm 会组出 rc.1/rc.2 混合 peer 图（3062 条 ERESOLVE）。现在钉一个**已完整发布**的 rc.2（修 ETARGET）并加 `NODE_OPTIONS=--max-old-space-size=4096`（修 OOM）。中途试过 `--legacy-peer-deps`，被真实 CI 否掉：它跳过的正是全局安装必须提供的 peer，`dsh-app-boot` 在 boot 时 require 的 `@deepseek-ai/cordis-plugin-group` 是 peer 而非 dependency，加了它 CLI 直接 `ERR_MODULE_NOT_FOUND`。

-- 📝 **新建标签页列表恢复可选说明**（#613）：DSH 0.1.5-rc.1 让 `SidebarRightGuideEntry.description` 回归（可选），插件随之恢复 `TabDescriptor.description`，六个内置类型各写回一条说明（原生指南的 文件 / 文件变动 / 任务管理 / 侧边对话 / 终端 / 浏览器 六行都带上它），`guideDesc*` 词条回到 20 份词典。**宿主的原生指南只在列出的条目 ≤ 4 条时渲染说明**（更长的列表是整列丢弃，不是截断），而插件默认贡献 6 个 guide 条目——因此默认组合下说明不渲染，只有在插件设置页关掉足够多的 tab 类型、把 guide 压到 ≤ 4 条时才会出现。未声明说明的条目仍是「图标 + 标题」单行（插件不补通用兜底句）。
-
-**🐛 修复**
-
-- 无。rc.1 相对 alpha.2 的 delta 很小（373 个变更文件，绝大多数是上游各包版本号、原生右侧栏预览 UI 打磨与测试快照），除上述说明字段回归（并附带上游 `files` 类型改用自己的彩色文件夹图标作指南字形）外，没有需要插件适配的变更。
-
-**🧰 CI 与内部**
-
-- 基线推进到 **DSH 0.1.5-rc.1+**（#613）：peer 下限、devDependency 钉版、CI 挂载车道与 `dsh.plugin.json` 的 `engines.dsh` 同步（rc.1 在 npm 上同时是 `latest` 与 `next`）。
-- 明确未变、不必再核：全局主面板模型（`main` 槽 / `sidebar.panellist` / `ctx.layout` / 根级 `rightbar` + `rightbar.session`，插件仍不接入）、文件地址语法（`packages/util/workspace-path` 只动了版本号）、原生 tab 体宿主契约（`.paneBody` 仍是有确定高度的块级滚动容器）、core / agent / session / subagent 宿主 API 与 `ui-primitives` 导出面（仅 CodeBlock 渲染变化）。
-- `@deepseek-ai/dsh-client-ui-primitives@0.1.5-rc.1` 仍不声明 `dependencies` 而 bundle 仍裸 import `anser` / `shiki` / `@shikijs/langs/*` / `mdast-util-*` / `micromark-*` / `katex`——上一版提升进 devDependencies 的那组包因此保留，不得回退。
-- 真机验证（DSH 0.1.5-rc.1 + 插件 0.19.0）：门禁 `typecheck` / `lint` / `check:consumer-types` 全绿，单测 **124 files · 1296 passed · 9 skipped**，`pnpm peers check` 干净；挂载冒烟对真实 rc.1 **7 passed**（含 tab 体填充断言，以及新增的「指南 ≤4 条时说明才渲染」断言）；本地 3080 实测：guide 六行仍是「图标 + 标题」（6 > 4，说明按上游规则不渲染；上游把胶囊 `min-height` 从 48px 调到 56px），文件树点击 `AGENTS.md` 落到插件编辑器（CodeMirror 就绪），sidechat 输入框贴底（宿主盒 962px == 面板体 962px，composer 底边距 8px），底部工作台与中心列左右边完全重合，`pageerror` 0（控制台仅有第三方 `dsh-tauri-worktree` 的 `/api/dsh-worktree/attach` 500，与本次改动无关）。
-
-### v0.19.0-alpha.1
-
-> 🧪 **alpha 通道**（npm dist-tag `alpha`，安装 `dsh-better-sidebar@latest`）：本版仅支持 **DSH 0.1.5-alpha.2+**（peer 下限 `^0.1.5-alpha.2`，CI 钉 `@deepseek-ai/dsh@0.1.5-alpha.2`）。0.1.5-alpha.1 请继续用 **v0.19.0-alpha.0**；0.1.2-rc.1 稳定线用 **v0.18.1**（npm `latest`）。
-
-**✨ 新功能**
-
-- 🪟 **每个 tab 体都填满面板**（#609）：原生右侧栏的 tab 体宿主是「有确定高度的块级滚动容器」而非 flex 容器，此前插件各 tab 的根只写 `flex: 1`，在块容器里塌成内容高度——侧边对话的输入框因此贴不到面板底（转录一长就被推出可视区）。现在 native 适配层统一给每个 tab 体包一层 `height: 100%` 的列 flex 宿主，插件全部 tab（含第三方 `registerTab` 注册的 descriptor）恢复与底部工作台一致的填满语义。
-
-**🐛 修复**
-
-- 🧭 **跟随 DSH 0.1.5-alpha.2 的文件地址语法**：`fileAddressFor` 一律产出 session 作用域地址、绝对路径保留前导 `/`；`parseFileAddress` 改为前缀解析并忽略 `?`/`#` 后缀。
-- 🪟 **底部工作台的中心列定位跟随 alpha.2 全局面板改动**：`conversation` 槽改为根级 `main` keyed 槽下的 `main.conversation`，定位器改认新 key 并跳过 `display: contents` 槽宿主（alpha.1 的旧 key 仍兼容）。
-
-**🧰 CI 与内部**
-
-- 基线推进到 DSH 0.1.5-alpha.2（#609）：peer 下限、22 个 devDependency 钉版、CI 挂载车道与 `dsh.plugin.json` engines 同步；`pnpm peers check` 干净（按 §3-9 补提 `dsh-session-persistence` 传递 peer）。
-- **移除 `TabDescriptor.description`**：alpha.2 的原生指南条目不再渲染第二行（改为「图标+标题」胶囊），该字段与 6 个 `guideDesc*` 词条（20 份词典）一并下线；新建标签页的默认页改由注册表选（恰好 1 个指南条目则直接打开它）。
-
-### v0.19.0-alpha.0

-
-**✨ 新功能**
-
-- 🖥️ **接入 DSH 原生右侧栏**（#604）：右列改为 DSH 自己的右侧栏——插件的 7 个 tab 类型全部注册成原生 tab 类型 + 原生 tab 体；聊天里的文件打开统一走 `ctx.sidebarRight.openResource(dsh-resource://file/…)`；`editor` 类型以 `extension` 优先级认领文件资源（压过内置文本预览）并接管内置「文件」页 kind（注销即复位）；跨会话打开在目标会话未上屏时排队重放。
-- 🧩 **退役插件自绘右侧面板与自由窗口**（#605）：右列归 DSH 后，插件只保留底部工作台（单分栏树、随会话持久化），开合按钮注册进 DSH 会话头 utilities 槽；浮窗 API（`floats` / `floatTab` / `dockFloat` / `raiseFloat` / 右键「移动到自由窗口」）、`features` 里的 `'floatWindows'`，以及 `openByDefault` / `defaultWidthPercent` / `changesDiffFloat` 三个设置项一并删除（旧持久化文档里的 `floats` 字段被忽略，不影响加载）。
-- 🔗 **适配 DSH 0.1.5 宿主契约**（#603）：`assistant/chunk` 事件删除 → 实时增量改由 `agent/assistant-stream` 帧折叠（侧边对话转录的 `live` 字段）；`sessionPersistence.inspect` 删除 → 冷会话读取改走 `open(id,'read')`；会话头 `version` 用 `SESSION_FORMAT_VERSION`。
-
-**🐛 修复**
-
-- 侧边对话转录 / `jobs.output` 回放 / fork 继承等 8 处会话事件读取跟随 0.1.5 契约；自定义种子补齐 fork 标记对，避免继承父会话未领取的 inbox 输入。
-
-**🧰 CI 与内部**
-
-- 真机挂载冒烟门禁钉 0.1.5-alpha.1，e2e 增加「展开原生栏 → 经引导页逐个打开插件 tab 类型」的巡检；typecheck / lint / 单测 / 挂载车道全绿。
-
-### v0.19.0（未发布）
-
-- 🎨 **可选彩色图标主题**：设置页「文件 → 文件图标」可在**内置单色**与**彩色品牌图标**之间切换——彩色主题含 563 条规则（218 扩展名 + 197 精确文件名 + 148 目录名，如 `.tsx → React`、`package.json → npm`、`node_modules` 着色），数据在**懒加载 chunk**（`lib/client-file-icons.js`）里，只有选中时才下载，默认关闭时启动零开销。数据源自 [#429](https://github.com/omdsh-dev/DSH-better-sidebar/pull/429)（@fenter）。
-- 🎨 **文件图标多样化 + 对外图标注册 API（[file-icons.tsx](./src/client/file-icons.tsx)）**：文件树与编辑器文件 tab 不再是单一 `VscFile`——markdown / 图片媒体 / PDF / JSON / 40+ 代码扩展 / 配置 / 数据库 / lock / 压缩包各有专属 glyph（VSCodicons 单色 `currentColor`，遵循皮肤契约），未知扩展回退通用图标。`ctx.betterSidebar` 新增 `registerFileIcon`（`features` 含 `'fileIcons'`）：按扩展名 / 精确文件名（`names`）/ 目录名（`folderNames`）注册自定义图标（彩色 ReactNode 亦可，颜色责任在注册方），`exts: []` 为全局默认（只兜内置 glyph 没认领的扩展，不吞掉内置多样性），保留扩展名 `'folder'` / `'folder-open'` 可换目录行图标；`fileIcon` / `folderIcon` 为权威解析器（完整回退链 + 逐工厂崩溃隔离），注册/注销即时生效。接入示例见[外部插件指南 §7](./docs/external-plugin-guide.md)。

-
-**🐛 修复**
-
-- 🔀 **git diff 折叠上下文真实展开**（#576，修复 #577）：折叠行此前显示「n 行…点击展开」却点不动（`-U3` 裁剪使 gap 段没有行文本）；现按需经 `git.show` 拉取两侧完整内容切片填充，带加载 / 失败降级三态与请求去重；顺带修复该路由的 `rev:path` 寻址（此前恒返空）
-- 💬 **侧边对话种子不再继承父会话未领取的 inbox 消息**（#562）：补 fork 标记对，消除「上下文很长时侧边对话先把之前的 User 消息发出去」的幽灵消息

-
-> 🧪 **alpha 通道**：本版仅支持 **DSH 0.1.2-alpha.x**（peer 下限 `^0.1.2-alpha.5`，npm dist-tag `alpha`）。该版本号当时未单独发布，内容已并入 **v0.18.0** 正式版；v0.19.0-alpha.0 这个号后来被 0.1.5 适配线复用（见上）。
-
-- 🔗 **适配 DSH 0.1.2-alpha.5（npm 已发布，`alpha` dist-tag）**：CI 挂载门禁钉版、`dsh.plugin.json` engines 下限与 `@deepseek-ai/*` peer / devDependencies 基线升至 0.1.2-alpha.5（真机挂载冒烟 14/14 验证）。`dsh-client-locale` 上游停在 0.1.2-alpha.3 未发新版，其 peer 下限 / devDep 保持并天然兼容 alpha.5 运行时（`pnpm peers check` 零失配，无需新增提升传递 peer）。代码适配了 alpha.4 的兼容性标记改动——`Session.events` 属性移除，迁移到按需读 API `snapshotEvents()`（sidechat 转录 live 读、fork 继承、`jobs.output` 回放、subagent 活跃度共 8 处），新建线程 meta 中宿主已删的 `seedLength` 一并移除；alpha.4 其余变化（双向 `send_message`、自定义模型发现复用 Profile 请求头、`SessionSeq`/`SessionLogOffset` 强类型）与 alpha.5（升级启动修复）经核实不触及本插件其余表面。

-> 🧪 **alpha 通道**：本版仅支持 **DSH 0.1.2-alpha.x**（peer 下限 `^0.1.2-alpha.2`，npm dist-tag `alpha`，安装 `dsh-better-sidebar@latest`）；不再支持 0.1.0-rc.8 ~ 0.1.1-rc.2——stable DSH 用户请用 v0.17.1（npm `latest`）。
-
-- 🔗 **适配 DSH 0.1.2-alpha.2（npm 已发布，`alpha` dist-tag）**：CI 挂载门禁钉版与 `@deepseek-ai/*` devDependencies 基线升至 0.1.2-alpha.2（真机挂载冒烟 14/14 验证）。适配点：`dsh-settings` 移除运行时导出 `settingsNamespace`（命名空间改为编译期校验，宿主侧直接传常量）；`dsh-subagent` 描述符版本 2→3（由宿主包盖章，测试断言跟随 `SUBAGENT_DESCRIPTOR_VERSION` 常量）；`SessionEvent.ignorable` 恢复与 Remote 网关 `RemoteError` 封装经核实对本插件无破坏。
-- 🐛 **修复 DSH 0.1.2-alpha.1+ 上侧边对话转录空白**：转录轮询此前仍走 alpha.1 已移除的 `ctx.connection.api`（错误被静默吞掉，tab 永远渲染空转录），现改由插件自有 `sidechat.events` 路由供给（活线程读内存事件日志、冷线程读会话持久化，`afterSeq` 增量拉取，[sidechat-routes.ts](./src/sidechat-routes.ts)）。
-- 🧹 **删除对 0.1.1-rc.x 及更早的兼容层**：e2e 宿主 RPC 从点分/斜杠双方言收敛为斜杠单方言（token URL 必选，[host-protocol.ts](./tests/e2e/host-protocol.ts)）；`MarkdownText` labels 收敛为嵌套单形状（[markdown-labels.tsx](./src/client/markdown-labels.tsx)，不再双 prop 名）；peerDependencies / devDependencies / `dsh.client.inject` / chunk externals 白名单四处同步清除已消亡的 `@deepseek-ai/dsh-client-runtime`。

-**✨ 新功能**
-
-- 🪟 **自由窗口**（[#354](https://github.com/omdsh-dev/DSH-better-sidebar/pull/354)）：把标签栏的任意 tab（内置或插件注册）**拖到主会话区域**——会话列出现虚线提示浮层，松开即成为悬浮窗口（默认 390×780，手机竖屏比例，创建时按视口钳制后居中于松点）；窗口支持头部拖动移动、右下角 SE 缩放（≥320×200）、点击任意处置顶、头部右键「回到侧边栏 / 关闭」、X 走 `closeTab` 正常关闭生命周期（释放终端等）；拖到侧边栏 pane 上时该 pane 高亮、松开即**停靠**合并回该 pane；`floats` 随会话持久化（刷新原样恢复，宽容 sanitize + 几何钳入视口）；服务语义：`features` 新增 `'floatWindows'`——`openTab` 的 dedupe/id 聚焦命中浮动 tab = **置顶窗口**（不重复开、不展开面板），`closeTab` / `activateTab` 对浮窗正常关窗 / 置顶并照常触发回调，浮窗内 tab `visible` 恒 true，agent 终端 reconcile 覆盖浮窗；tab 内容复用常规渲染、插件 tab 与 pane 完全同契约；附带文件二级页面 8px 网格间距规整（[设计文档](docs/plans/2026-08-23-free-window-design.md)）
-- 📂 **模型主动打开（`sidebar_open` 工具）**（[#353](https://github.com/omdsh-dev/DSH-better-sidebar/pull/353)）：侧边栏新增全局设置 `agentOpenTools`（**默认关闭**），开启后向模型注入**一个**工具——模型可在调用方会话的侧边栏打开本地**文件**（editor tab，按 path 去重）、**文件夹**（全窗树窗口，以该目录为根，`meta.dir`）与 **HTTP(S) 网页**（browser tab，URL 预填）；关闭设置即注销工具并清空未投递队列，已打开 tab 保留；非激活会话的打开排队、下次可见时重放（`/sidebar/ws/agent-opens` 推送，同一 trust fence）；无新增公共 API、不改变 `BetterSidebarService`（[设计文档](docs/plans/2026-08-23-agent-open-tools-design.md)）
-- 📝 **Markdown README 级内嵌 HTML + 目录大纲（TOC）**（[#360](https://github.com/omdsh-dev/DSH-better-sidebar/pull/360)）：Markdown 预览现在真实渲染**块级内嵌 HTML**——徽章墙 `<div align=center>`、`<details>` 折叠块内嵌 markdown、表格单元格 `<br/>`/`<sub>`/`<img>`、`<video>`/`<picture>` 全部经 DOMPurify 白名单消毒（`<script>` 等活性内容剥除、`<a>` 强制 `_blank rel=noopener`），本地媒体 src 重写为会话媒体路由；≥3 标题出现浮动**目录大纲**按钮，点击平滑滚动并自动展开折叠 `<details>`，HTML 段内标题同样收录；渲染器仍是宿主 `MarkdownText`（shiki / KaTeX / GFM 保留），纯 markdown（零 HTML）文档走原路径零回归（[设计文档](docs/plans/2026-08-24-markdown-html-toc-design.md)）
-- 🌏 **第三语言覆盖（19 语言）**（[#339](https://github.com/omdsh-dev/DSH-better-sidebar/pull/339)）：接入可选 peer `@huanlin/dsh-plugin-better-locale`——ja / de / fr / pt / ko / ar / hi / id / tr / vi / th / ru / it / nl / sv / pl / zh-HK / zh-TW / zh-MO 全量词典（每种约 340 keys）；覆盖**借用 DSH 英文槽位**（DSH active=en 时生效，zh 下完全惰性、界面不混语言）；19 语言词典同时注册进 better-locale，外部 `ctx.locale.lookup('betterSidebar', key)` 调用者同样可拿覆盖文本；未安装时 `ctx.get('betterLocale')` 为 undefined、整段 no-op，zh/en 行为不变
-- 🌿 **Git 多仓库选择 + linked worktree 变更发现**（[#326](https://github.com/omdsh-dev/DSH-better-sidebar/pull/326) [#285](https://github.com/omdsh-dev/DSH-better-sidebar/pull/285)）：会话 cwd 是工作区容器（非 Git 仓库）时自动发现直接子仓库并显示**仓库选择器**——status / 分支 / 历史 / diff / 暂存 / 提交 / 还原 / cherry-pick / 文件打开全部按所选仓库线程化；linked worktree 的变更发现与按工作树操作（含延迟分页响应的事务一致性），并拒绝过期 / 可修剪的 worktree 命令目标、对单库存取失败降级
-- 🖥️ **浏览器本地回环允许清单**（[#365](https://github.com/omdsh-dev/DSH-better-sidebar/pull/365)）：新增侧边卡设置 `browserAllowedLoopback`（逗号分隔 host 或 host:port；裸 host 匹配任意端口、带有端口精确匹配）——显式信任的本地开发服务器（如 Vite）可导航，并额外获得 iframe `allow-same-origin` 令牌（模块 / HMR / fetch 管线需要真实 origin，否则白屏）；页面相对 GUI 与其他站点仍是跨源；服务端 `browser.probe` 镜像同一允许清单，本地服务器不再被误拒
-- 📝 **编辑器 Vue + 28 种 legacy 语言语法高亮**（[#202](https://github.com/omdsh-dev/DSH-better-sidebar/pull/202)）：`.vue` 映射 `@codemirror/lang-vue`（template / script / style 按 `lang` 属性分派、`<style lang="scss">` 预处理器）；零新依赖用 legacy-modes 补齐 scss/sass/less/stylus/ruby/lua/perl/r/dart/scala/groovy/powershell/diff/protobuf/cmake/pug/tcl/haskell/clojure/erlang/julia/pascal/vb/vhdl/stex/objectivecpp；语言工厂抛错降级纯文本（console.warn），不再炸编辑器；`.v` / `.m` 跨语言歧义故意不映射
-- 🔄 **编辑器预览刷新三件套**（[#215](https://github.com/omdsh-dev/DSH-better-sidebar/pull/215) [#228](https://github.com/omdsh-dev/DSH-better-sidebar/pull/228)，修复 [#167](https://github.com/omdsh-dev/DSH-better-sidebar/issues/167)）：文本预览新增**手动刷新**按钮；编辑保存后切回预览自动重载（dirty 时抑制，草稿不丢）；预览模式下保存成功边沿自动重载；移除自动轮询与 `fs.stat` 版本端点（后台 API 零流量）
-- 🖼️ **Markdown 本地 / 相对图片**（[#292](https://github.com/omdsh-dev/DSH-better-sidebar/pull/292)）：`![alt](./img.png)`、`/cwd/img.png` 与引用式 `[id]: url` 目标重写为 `/sidebar/file` 媒体 URL（会话 cwd 边界不变）——预览不再只显示 alt 文本
-- ➕ **推荐插件目录新增 ego-browser**（[#340](https://github.com/omdsh-dev/DSH-better-sidebar/pull/340)）：`@dsh-external/ego-browser` Agent 浏览器 Tab（会话侧边栏自动注册本机浏览器页，无 better-sidebar 时回退浮动浮窗）；描述词典 19 语言补全（[#371](https://github.com/omdsh-dev/DSH-better-sidebar/pull/371)）

-**🐛 修复**
-
-- 🛒 **DSH 市场受管安装兼容**（[#338](https://github.com/omdsh-dev/DSH-better-sidebar/pull/338)）：移除 `peerDependencies` 里的公开版 `cordis`（市场预览硬拒依赖字段出现 `cordis`，optional 无效）——npm 包满足 [dsh-community-market 安装规范](https://github.com/anywhere-labs/deepseek-harness-desktop/blob/master/dsh-community-market/docs/install-and-uninstall.zh.md)，dshfind / 1024Store 目录里的条目重新获得 `repository_backlink` 验证目标，可直接从 Desktop 市场受管安装
-- 🔤 **类型基底迁移到 `@deepseek-ai/cordis`**（[#338](https://github.com/omdsh-dev/DSH-better-sidebar/pull/338)）：`Context` = 真实 vendored cordis Context 与结构化服务面的**交集**，`ctx.betterSidebar` 类型合并改挂 `@deepseek-ai/cordis`，公开版 cordis 不再被依赖。**消费者迁移**：`import type { Context } from 'cordis'` 改为 `import type { Context } from '@deepseek-ai/cordis'`（`import type {} from 'dsh-better-sidebar'` 的类型合并方式不变）；未使用该导入的插件无影响
-- 🧩 **插件树内 `ctx.betterSidebar` 读取全面修复**（[#357](https://github.com/omdsh-dev/DSH-better-sidebar/pull/357)，修复 [#356](https://github.com/omdsh-dev/DSH-better-sidebar/issues/356)）：npm 安装的 DSH 0.1.1-rc.x（web bundle）下侧边栏页面每次加载即崩（`cannot get property "betterSidebar" without inject`）——26 处内部直读 `ctx.betterSidebar` 改走 `ctx.get('betterSidebar')`（root reflect store 解析，不受 fiber 链影响）；外部消费者 `inject: ['betterSidebar'] + ctx.betterSidebar` 契约不变
-- 🔐 **文件 API 会话工作区边界**（[#345](https://github.com/omdsh-dev/DSH-better-sidebar/pull/345)，修复 [#328](https://github.com/omdsh-dev/DSH-better-sidebar/issues/328)）：`fs.tree / fs.read / fs.write` 的 workspace 越界访问修复；媒体、HTML 预览与上传统一 real-path 符号链接校验；新增绝对路径 / 符号链接 / 上传 / 嵌套 Git 会话回归测试
-- 🪟 **面板宿主层级与视口裁剪**（[#330](https://github.com/omdsh-dev/DSH-better-sidebar/pull/330) [#278](https://github.com/omdsh-dev/DSH-better-sidebar/pull/278)，修复 [#277](https://github.com/omdsh-dev/DSH-better-sidebar/issues/277)）：面板宿主层 z-index 40→25——低于 DSH cordis 动态插件面板 30，工作台不再遮挡 cordis 清单 / 审批面（AppFrame 20 之上、100+ 浮层之下）；宿主 `overflow: hidden` 裁剪视口边缘，收起的面板不再把文档撑出双向滚动（实测 `scrollWidth` 2289→1672 / `scrollHeight` 1280→1032，任意皮肤）
-- 📐 **布局推挤加固**（[#310](https://github.com/omdsh-dev/DSH-better-sidebar/pull/310) [#130](https://github.com/omdsh-dev/DSH-better-sidebar/pull/130) [#180](https://github.com/omdsh-dev/DSH-better-sidebar/pull/180)）：对话列补 `min-height: 0` + `overflow: hidden` + `overflow-wrap: anywhere`（长不可断 URL / OAuth 链接不再把 composer 与左侧设置按钮挤出视口）；layout-push effect 拆「仅设置 + 仅卸载移除」并按 `panelOpen` 门控宽度 push——右栏关闭时拖底部高度不再挤压对话区、松手瞬间不再整页右铺再回弹；`useLayoutEffect` 消除跨 paint 全宽闪帧；松手 flush 最终帧 + `centerRect.right` 同步提交；底部高度按 `viewportHeight - PANEL_MIN` 封顶；拖拽手柄拖动中不再高亮
-- 📱 **移动端无会话状态说明 + 1px 溢出修复**（[#254](https://github.com/omdsh-dev/DSH-better-sidebar/pull/254)）：无会话时开关改用 `aria-disabled` 保持不可执行语义、同时允许触摸 / 键盘聚焦显示「选择一个会话以使用侧边栏」提示；panel 改 `border-box`——移动端 `100vw` 含左边框，不再产生 1px 横向溢出
-- 📏 **侧边栏宽度跨会话共享**（[#36](https://github.com/omdsh-dev/DSH-better-sidebar/pull/36)）：面板宽度是布局偏好而非会话内容——「最后一次拖拽胜出」写入全局 `dsh-sidebar:v1:width`，缓存会话切换与新建会话即时跟随；无全局键（首次运行 / 旧会话）时行为逐字节不变
-- 🧹 **会话删除立即关闭该会话终端**（[#130](https://github.com/omdsh-dev/DSH-better-sidebar/pull/130)）：新增 `PtyManager.closeSession()` + 订阅 DSH `session/disposed`——删除会话不再等 30s 重连宽限到期（agent 终端由 agent 生命周期管理，不受影响）
-- 🔍 **文件名搜索跳过噪声目录**（[#342](https://github.com/omdsh-dev/DSH-better-sidebar/pull/342)）：`node_modules` / `.pnpm-store` / `.yarn` / `.turbo` / `.next` / `dist` / `build` / `coverage` 等黑名单（小写不敏感，`.git` 仍跳）——超大依赖树不再耗尽 10 万访问预算提前 `truncated`，`docs/` 等后序目录里的真实文件能搜到；不引入 `.gitignore` 语义，保持「文件名查找」
-- 📝 **mermaid 全局错误渲染抑制**（[#341](https://github.com/omdsh-dev/DSH-better-sidebar/pull/341)）：开启 `suppressErrorRendering`——非法图表不再把大错误 SVG 注入 `document.body`；组件级错误回退与源码展示保留
-- 🖥️ **终端 Nerd Font 图标字体回退**（[#190](https://github.com/omdsh-dev/DSH-better-sidebar/pull/190)）：starship / powerlevel10k 提示符的补充平面 PUA 图标（Nerd Fonts v3 Material 图标集）不再显示豆腐块——`withIconFontFallbacks()` 为胜出的基础字体追加 Nerd Font 图标族（插入首个通用族之前、按族名去重、过滤 CSS 全局关键字、不列彩色 emoji 字体）
-- 🌐 **HTML 预览 UTF-8 声明**（[#193](https://github.com/omdsh-dev/DSH-better-sidebar/pull/193)，修复 [#170](https://github.com/omdsh-dev/DSH-better-sidebar/issues/170)）：`/sidebar/html` 响应带 `charset=utf-8`（无 `<meta charset>` 的中文片段不再乱码），保留原始文件字节
-- 🧪 **trust-fence Origin 改按 hostname 比较**（[#182](https://github.com/omdsh-dev/DSH-better-sidebar/pull/182)）：Edge 151 把非默认端口 loopback 页面的 Origin 序列化为无端口形式——`http://127.0.0.1` 对 `Host: 127.0.0.1:3080` 不再 403（对齐 DSH 官方网关栅栏）；不同 hostname / opaque null origin 仍拒绝
-- 🪟 **「在文件夹中显示」改为资源管理器揭示**（[#94](https://github.com/omdsh-dev/DSH-better-sidebar/pull/94)）：不再把目录当文件开进编辑器（`"..." is a directory`）——`revealInExplorer` 切到资源管理器 tab、面板折叠时自动展开、展开父目录并高亮滚动到本轮产出文件；产物行数据改读引擎 Turn deliverable（与 ui-deliverables 同源）
-- 🖱️ **面板拖动布局闪烁**（[#180](https://github.com/omdsh-dev/DSH-better-sidebar/pull/180)）：右侧栏关闭时拖底部高度不再左移挤压对话区；松手瞬间不再整体右铺再回弹
-- 🖥️ **PowerShell 安装脚本修复**（[#47](https://github.com/omdsh-dev/DSH-better-sidebar/pull/47)）：远程入口统一为「下载脚本 → 移除 UTF-8 BOM → 内存执行」，`-Version` / `-DryRun` 参数在 Windows PowerShell 5.1 下恢复生效（BOM 解析不再吃掉首行 `param(...)`）；安装前校验 `pnpm --version`（主版本 <10 时明确报错并以退出码 1 结束，不再写一半 profile）
-- 🔄 **浏览器嵌入探测 GET 兜底**（[#69](https://github.com/omdsh-dev/DSH-better-sidebar/pull/69)）：HEAD 响应同时缺 CSP 与 X-Frame-Options 时回退 GET 重试一次——阿里云百炼等只在 GET 回头发嵌入策略的站点不再显示误导性「拒绝连接请求」，而是正确显示「该站点拒绝嵌入」面板 + 「在浏览器中打开」
-- 🔧 **git 源安装修复 `unrun` devDependency**（[#336](https://github.com/omdsh-dev/DSH-better-sidebar/pull/336)）：tsdown 0.22 经 `unrun` 加载配置而 pnpm 11 不自动装 peer——git-hosted 安装的 `prepare` 不再报 `Failed to import module "unrun"`（npm tarball 不受影响）
-- 🍃 **`ctx.effect` 严格化顺手修了 4 处**：拦截注册失败时 effect 体返回 `undefined` 改为 no-op disposer（vendored cordis 的 effect 契约要求返回 disposer，返回 `undefined` 属非法形状）

-**✨ 新功能**
-
-- 🗂️ **文件树「在应用中打开」子菜单**（[#334](https://github.com/omdsh-dev/DSH-better-sidebar/pull/334)）：文件树右键菜单新增「在应用中打开 >」子菜单——内置打开方式（资源管理器显示/选中、VS Code、Cursor、Zed），每行右侧图钉可固定为右键菜单顶层直达项（再点取消）；配置可选 SSH host 后 VSCode 系条目改用 `vscode-remote/ssh-remote+<host>/<path>` 协议打开，本地专用条目自动隐藏；支持自定义编辑器（名称 + URL 模板 `{path}` + 是否 VSCode 系，配置入口在 Files 卡片齿轮弹窗）。打开动作经新宿主路由 `POST /sidebar/api/open.external`（argv 数组 spawn，无 shell 注入）（[设计文档](docs/plans/2026-08-22-open-with-menu-design.md)）
-- 📑 **Tab 右键菜单**（[#331](https://github.com/omdsh-dev/DSH-better-sidebar/pull/331)）：页签右键提供「关闭 / 关闭其他页签 / 关闭左侧页签 / 关闭右侧页签」，作用范围为当前 pane（标签组），无可关对象时置灰；仅打开菜单、不切换激活页签；批量关闭逐条走既有 `onClose` 路径，生命周期完整
-- 📄 **Diff 文件默认折叠**（[#270](https://github.com/omdsh-dev/DSH-better-sidebar/pull/270)）：改动文件头部改为可访问的展开/折叠控件；识别出的源文件默认展开，测试 / 文档 / 生成文件 / lockfile 与未知类型默认折叠；保留现有 500 行上限

-
-- 🪟 **空分栏清理**（[#268](https://github.com/omdsh-dev/DSH-better-sidebar/pull/268)）：持久化的 split pane 在临时 diff tab 被清理后遗留全尺寸空分栏——`sanitizeState` 现在同时修剪空的 split leaf，并修复修剪后的失效激活 pane 指针；整个工作台为空时保留唯一空 pane
-- 🖥️ **Windows 下隐藏 Git 子进程窗口**（[#301](https://github.com/omdsh-dev/DSH-better-sidebar/pull/301)，关闭 [#124](https://github.com/omdsh-dev/DSH-better-sidebar/issues/124)）：`runGit()` 统一加 `windowsHide: true`，仓库状态轮询与操作不再闪现控制台窗口（其他平台行为不变）
-- 📁 **未跟踪文件夹内文件差异**（[#242](https://github.com/omdsh-dev/DSH-better-sidebar/pull/242)）：`git status` 从 `--untracked-files=normal` 切换为 `--untracked-files=all`——新文件夹内每个文件独立成行、可正常加载差异（修正 `fs.read` 报 "is a directory"，与 VSCode 默认行为一致）
-- ⚡ **开关/拖拽每帧 React 重渲染消除**（关闭 [#315](https://github.com/omdsh-dev/DSH-better-sidebar/issues/315)）：centerRect 改 ref + 底栏 DOM 直写（零 React 渲染）；TabContent memo（显式比较器）；新增 frame-batcher 对 Divider/dock 拖拽按帧合并；拖拽期跳过无意义 locate。4x CPU 节流 A/B：开关 >17ms 帧 collapse 19→6 / expand 24→4~6，p95 21ms→15ms；拖拽不变（非回归）

-- 💬 **侧边对话 Codex 风格转录重构**（[#314](https://github.com/omdsh-dev/DSH-better-sidebar/pull/314)）：转录改为**折叠行**——工具调用 / 思考 / 上下文注入统一为安静的单行 chrome（chevron + 标签 + 单行参数摘要，展开为 hairline 缩进正文，无卡片无填充），流式标签与创建 shimmer（shimmer = 生成中）、失败工具 danger、`prefers-reduced-motion` 停帧；**首条问题不再被边界提示吞掉**——上下文注入与首问拆分交付（边界 + 快照经 `agent.inject` 排队、问题唤醒驱动），转录把注入映射为可折叠注入行、真实用户消息（**含首问**）渲染为用户气泡，旧线程的首问同样拆分为独立气泡
-- 📖 **README 重写**：功能导览（逐特性实机截图）、用户视角 DSH 兼容徽章、简化安装流程（`add` → `approve-builds` → `add`、node-pty 安全构建、粘贴到 DSH 安装提示）、插件生态 28+ 与分类折叠展示
-
-**🐛 修复**
-
-- 🖥️ **终端跨会话切换保活**（[#323](https://github.com/omdsh-dev/DSH-better-sidebar/pull/323)）：切到其他会话不再被当作瞬时掉线——客户端卸载时发送 `park` 控制帧，主机跳过 30s 重连宽限倒计时；切回会话（`open()` 取消 parked）或显式关闭恢复正常生命周期；agent 终端保持无限期存活
-- 📂 **文件树上传遮罩不再拦截 Tab 拖拽**（[#317](https://github.com/omdsh-dev/DSH-better-sidebar/pull/317)）：拖拽 Tab（重排 / 跨 pane split）经过资源管理器时不再弹上传遮罩、不吞事件——统一按 `dataTransfer.types` 含 `Files` 门控（与面板宿主 shield 一致），Tab 正常落下；OS 文件拖拽行为不变
-- 💬 **子代理自动展开去抖**（[#314](https://github.com/omdsh-dev/DSH-better-sidebar/pull/314)）：Side Chat 线程创建不再误弹任务页——0→N 触发 500ms 重臂并对实时快照按原基线重评估，标题过滤器识别线程后才放行；真实子代理依然自动激活任务页（宽屏展开侧边栏，窄屏只准备 Tab、不强制展开抽屉）

-- 💬 **侧边对话(beta) Tab**（[#286](https://github.com/omdsh-dev/DSH-better-sidebar/pull/286)）：Codex 风格的侧边线程，**每个对话一个独立 Tab**——子会话继承主会话完整上下文（已完成回合 + 未回答消息 + 进行中回合的 assistant 输出与工具调用，以「interrupted」冻结标记诚实继承）；同组合创建（同 preset / provider / model）复用前缀输入缓存；线程对主会话列表不可见、零子代理目录噪音；线程内可持续追问（重启后自动冷恢复）；一键「保存为新会话」提升为顶层会话（[设计文档](docs/plans/2026-08-20-sidechat-tab-design.md)）
-- 📤 **文件窗口上传**（[#239](https://github.com/omdsh-dev/DSH-better-sidebar/pull/239)）：头部「上传文件 / 上传文件夹」按钮 + 拖放上传（拖到树区 = 工作区根，目录行 = 进该目录，文件行 = 进其所在目录，对齐 VSCode）；上传时全屏模糊进度弹层（文件级进度 + 取消 / Esc）；上传中按钮禁用、成功后文件树自动刷新
-- 🧩 **桌面兼容四选项**（[#284](https://github.com/omdsh-dev/DSH-better-sidebar/pull/284)）：位置兼容模式改为**主行下拉**——**自动检测**（默认，保守：仅使用标准的 Window Controls Overlay 几何，32/36px 等各壳差异自动跟随、最大化/还原实时更新，网页环境零修改）/ **DSH官方Web**（显式零适配）/ **壳兼容方案**（内置预设，手动启用；只收录 issue/PR 中出现过且 100+ star 的壳，命中环境带「已检测」提示）/ **自定义方案**（自定义 CSS + 下移距离）。旧版本已有兼容配置的用户自动落到自定义方案；交互控件统一退出桌面拖拽区（`no-drag`）；底栏推挤锚点复合选择器双保险（`[data-pane]` 与 `:has(> [data-slot])`）
-- 🎛️ **设置页 UI/UX 现代化**（[#300](https://github.com/omdsh-dev/DSH-better-sidebar/pull/300)）：侧边卡片二级设置入口改为卡片底部「功能设置」设置条（替代右下角隐形齿轮，可发现性提升）；协调双色启用态（brand 激活强调 + success 绿勾选徽标）；全部颜色仍为 `--dsw-alias-*` 令牌派生，皮肤体系自动跟随
-- ➕ **推荐插件目录新增**：`dsh-docs-panel` 全局文档面板（[#230](https://github.com/omdsh-dev/DSH-better-sidebar/pull/230)）、`dsh-flowglass`（[#261](https://github.com/omdsh-dev/DSH-better-sidebar/pull/261)）、`dsh-git-forge` 与 `dsh-ssh-tunnel`（[#204](https://github.com/omdsh-dev/DSH-better-sidebar/pull/204)）、`dsh-turn-review`（[#102](https://github.com/omdsh-dev/DSH-better-sidebar/pull/102)）

-**🐛 修复**
-
-- ⚡ **子代理页实时预览批量接口**（[#298](https://github.com/omdsh-dev/DSH-better-sidebar/pull/298)）：旧实现每个 running 子代理独立轮询 `subagents.history`，host 侧每次触发全量子代理枚举形成 O(N²) 放大、多子代理并发时页面卡顿——改为单个批量接口 `subagents.live`（一次枚举整棵子代理树）+ 客户端单轮询、单在途请求；展示逻辑与文案不变
-- 🖱️ **拖拽中断 / 快速释放不再回滚**（[#249](https://github.com/omdsh-dev/DSH-better-sidebar/pull/249)，关闭 [#247](https://github.com/omdsh-dev/DSH-better-sidebar/issues/247) [#248](https://github.com/omdsh-dev/DSH-better-sidebar/issues/248)）：中断 / 快速释放提交最后已知位置；HMR 后中心列重定位兜底（修复热更新后底栏空白）

-- 🔒 **上传链路安全加固**（[#239](https://github.com/omdsh-dev/DSH-better-sidebar/pull/239)）：`relativePath` 空段 / 绝对路径显式拒绝；临时文件唯一命名（并发上传互不干扰、崩溃不阻塞）；写流错误监听（磁盘失败不崩溃进程）；客户端错误码与服务端统一、413 本地化
-- 🔐 **文件 API workspace 边界加固**（[#328](https://github.com/omdsh-dev/DSH-better-sidebar/issues/328)）：`fs.tree/read/write`、媒体、HTML 预览和上传统一按真实路径限制在会话 workspace 内，拒绝越界绝对路径与外链符号链接

-- 🖼️ **统一面板宿主注入重构**（[#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)）：面板/开关簇迁入 `[data-dsh-panel-host]` 固定含块层（`fixed inset-0 z-40`），免疫桌面套壳中间层 transform 对 fixed 含块的劫持；挂载自检（页面级 transform → `data-dsh-panel-host-degraded` 降级同步，按未修正几何判定、祖先变换消失才退出）；推挤锚点改 `#root [data-dsh-frame] > [data-pane="conversation"]` + `#root` calc 宽度防桌面壳加性溢出；chunk 激活重验证（HEAD+ETag 保留未变 chunk，5s 超时兜底 fail-open）；`visualViewport` 键盘 inset + `env(safe-area-inset-*)` 移动端适配
-- 📂 **文件打开方式默认独立**（[#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)）：`editorExplorer` 默认从「合并」改为「独立」——新会话树点击 / 打开文件按路径**新开**文件 tab，无路径窗口即纯资源管理器；合并模式保留为可选手动开启
-- 🖥️ **终端 shell / shellArgs 设置页可配**（[#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)）：终端卡齿轮二级页面新增「Shell 路径」「Shell 参数」两行配置（此前只能通过 `cordis.patch.yml` 配置）——设置页写入后对**之后打开的** UI 终端与模型终端（`terminal_create`）即时生效；留空保持 yaml → `$SHELL` / 登录 shell / `powershell.exe` 的既有解析顺序
-- 🏷️ **设置页版本徽标**（[#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)）：侧边卡片设置页顶部新增 `DSH-better-sidebar v0.14.0` 身份徽标（版本与服务实例同步，由测试守护）

-- 🧩 **rc.8 模块系统迁移**（[#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)）：rc.8 不再暴露 `window.__DSH_MODULES__` 页面全局（改由 `ctx.modules` 服务提供），懒加载 chunk 的外部依赖解析全面失效——client 注入 `modules` 服务 + 插件自有全局共享给 chunk 副本（终端 / 编辑器 / Mermaid 恢复正常按需加载）
-- 🧩 **chunk 重验证屏障健壮性**（[#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)）：HEAD 重验证加 5s 超时兜底（路由挂起时 fail-open 重取，屏障不再可能无限期阻塞懒加载）；`resetChunks` 清挂起的重验证屏障
-- 🖱️ **拖拽健壮性**（[#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)）：快速释放（浏览器合并 / 丢失 pointermove 突发）时提交最后已知拖动位置而非回退；`pointercancel` / 捕获丢失中断同样保留拖动结果；提交后立即重测中心列（消除底栏宽度中间帧抖动）；HMR 重激活后中心列重定位兜底（`<html>` 样式观察 + 底栏打开重测），修复热更新后底栏空白 / 输入框位移

-- 🔗 **聚合双挂载自动退让**（[#200](https://github.com/omdsh-dev/DSH-better-sidebar/pull/200)）：聚合包（如 dsh-web-ui-all）以独立条目 id 挂载同包时，`cordis.patch.yml` 的守卫表达式自动禁用自身 `better-sidebar` 行，不再重复注册 `/sidebar/api` 导致 `duplicate prefix route` 整个插件树启动失败（`dsh web` 崩溃）；独立安装行为不变
-- 🔧 **适配 DSH 0.1.0-rc.7**（[#207](https://github.com/omdsh-dev/DSH-better-sidebar/pull/207)，修复 [#206](https://github.com/omdsh-dev/DSH-better-sidebar/issues/206)）：修复 DSH 主框架升至 rc.7 后选模型 / 发消息报 `agent-presets: refusing to compose an unscoped context` 的问题
-
-### v0.13.0
-
-**✨ 新功能**
-
-- 📁 **文件窗口与资源管理器二合一**（[#151](https://github.com/omdsh-dev/DSH-better-sidebar/pull/151)）：新 `editorExplorer` 设置（编辑器卡齿轮）——文件 tab 增加路径输入框头部 + 可开关的右侧停靠文件树（每 tab 记忆展开/宽度，左缘拖拽调宽 160~480px，全局文件名搜索走 host `fs.search` 路由，预算封顶并跳过 `.git` / 符号链接目录）；独立模式（默认）树点击 / 输入框 Enter **按路径新开**文件 tab，合并模式**原地切换**当前 tab；新会话默认 seed 空文件窗口（`Files`）替代 explorer tab，无路径窗口在独立模式为纯资源管理器、合并模式为带 chrome 的空文件窗口；树右键提供「在新 Tab 中打开」「在侧边打开」（split）
-- 🎛️ **声明式设置 select 行**（[#151](https://github.com/omdsh-dev/DSH-better-sidebar/pull/151)）：设置项新增 `type: 'select'`（`options` 支持 value/title/desc/icon，`multi` 多选存数组）；带图标的选项渲染大图标选项卡、收起态同样显示图标；`editorExplorer` 改为图标化下拉（合并 / 独立）；能力清单新增 `settingSelect`
-- 🔀 **与 dsh-web-ui 家族右侧面板互斥**（[#181](https://github.com/omdsh-dev/DSH-better-sidebar/pull/181)）：读取 `aionui-panel` 设置命名空间的提供方选择——当选择「使用 aionui-panel」时，整个 better-sidebar（右侧栏 / 底部面板 / 浮动入口 / 各类接管）不再挂载；选择 DSH-better-sidebar（或未安装 aionui）时正常。设置页保存后实时生效（settings-document 推送），无需刷新
-
-### v0.12.3
-
-**✨ 新功能**
-
-- 🎨 **皮肤兼容（令牌驱动）**：全面消费 DSH 设计令牌，与 dsh-web-ui 皮肤中心 10 款皮肤兼容，换肤自动跟随；终端/编辑器表面在透明/半透明玻璃值下回退不透明底色，文字不叠在皮肤背景上（[#110](https://github.com/omdsh-dev/DSH-better-sidebar/pull/110)，修复 #106 #105 #90 #60，附带 #52 #57 #92）
-- 🗂️ **统一路径处理**：UNC 路径 / 软链接分类（目录软链接可展开、失效链接标红）、HTML 路由平台守卫（[#134](https://github.com/omdsh-dev/DSH-better-sidebar/pull/134)，#65 #67 #43 #79 #115）
-- 🖥️ **终端 shell 可配置**：设置项自定义 shell，Windows 自动探测 pwsh（[#95](https://github.com/omdsh-dev/DSH-better-sidebar/pull/95)）
-- 📝 **编辑器新增语言**：C# / Kotlin / Swift 语法高亮（[#120](https://github.com/omdsh-dev/DSH-better-sidebar/pull/120)）
-- 🧭 **设置页导航图标**：设置页导航图标与布局优化（[#114](https://github.com/omdsh-dev/DSH-better-sidebar/pull/114)）
-- ➕ **推荐插件目录新增**：`dsh-git-remotes`——Git 远程 Tab（分支/上游/ahead-behind、fetch 可 prune、ff-only pull、确认后才 push，不替换内置暂存/提交）（[#91](https://github.com/omdsh-dev/DSH-better-sidebar/pull/91)）；`dsh-video-preview`——视频内联预览（.mp4/.webm/.mov/.mkv/.avi 等，自带 /video 宿主路由支持 HTTP Range 206 拖进度条，不受 20MB mediaLimit 限制）（[#126](https://github.com/omdsh-dev/DSH-better-sidebar/pull/126)）
-
-**🐛 修复**
-
-- 🔧 **xterm 依赖迁移**：弃用的 xterm 迁移至 `@xterm/xterm`（Closes [#122](https://github.com/omdsh-dev/DSH-better-sidebar/issues/122)，[#128](https://github.com/omdsh-dev/DSH-better-sidebar/pull/128)）
-- 📝 **Markdown 编辑器**：选区转对话弹窗恢复可用（[#24](https://github.com/omdsh-dev/DSH-better-sidebar/pull/24)）
-- 🖼️ **Markdown 预览支持本地/相对路径图片**：预览 `.md` 时把指向本地文件的图片目标（相对/绝对路径、引用式 `[id]: url`）重写为 `/sidebar/file` 媒体 URL 并显示（此前仅绝对 http(s) 图片能渲染，相对路径只显示 alt 文本）
-- 🐛 **node-pty 加载失败不再拖垮 server**（[#140](https://github.com/omdsh-dev/DSH-better-sidebar/issues/140)）：宿主半改为懒加载 node-pty，缺失时插件照常挂载，终端以修复提示横幅（可复制命令 + 重试按钮）呈现，agent 终端工具自动跳过
-- 🧪 测试工程：单元测试拆分（#141）+ smoke 偶发失败修复

-## 🔌 服务化扩展
-
-从 v0.4.0 起暴露 `ctx.betterSidebar` 服务，其他插件可注册侧边栏页面与文件预览器（内置 5 tab + 3 viewer 亦通过同一服务注册）。v0.12.1 补齐基座能力（完整类型导出、能力探测、状态订阅、tab 角标、生命周期回调、定向打开、插件自有设置等）。v0.19.0 起新增文件图标注册：`registerFileIcon` 按扩展名（或保留的 `'folder'` / `'folder-open'` 目录扩展名、`exts: []` 全局默认）替换文件树与文件 tab 的图标，彩色 ReactNode 亦可——内置消费、注册即生效，无需自己接线。
-
-完整接入文档（全字段、匹配算法、HMR 陷阱、声明式设置、版本探测、原生栏承载面与皮肤契约）：**[`docs/external-plugin-guide.md`](./docs/external-plugin-guide.md)**；仓库开发规则（硬约束 / CI / 发版）见 [`AGENTS.md`](./AGENTS.md)。
-
-### ➕ 添加插件（推荐插件目录）
-
-设置页「侧边卡片」两个网格末尾的**虚线卡片**分别打开 Tab / 预览插件弹窗：声明扩展点、「**在 GitHub 上浏览更多插件**」按钮（[GitHub topic `dsh-better-sidebar`](https://github.com/topics/dsh-better-sidebar)）、推荐插件目录（名字 / 仓库 / 简介 / 安装脚本），每个条目「**跳转**」直达仓库、「**复制**」把安装命令写入剪贴板。
-
-**收录新插件**：向 [`src/client/plugins-tabs.ts`](./src/client/plugins-tabs.ts)（Tab 注册）或 [`src/client/plugins-viewers.ts`](./src/client/plugins-viewers.ts)（文件预览注册）追加一条 `PluginEntry`，并把仓库打上 `dsh-better-sidebar` topic；数据完整性由 `tests/plugin-list.spec.ts` 守护。
-
-## 🛠️ 开发与构建
-
-```sh
-pnpm install      # @deepseek-ai/* devDependencies 已发布（基线 0.1.7-rc.1，alpha dist-tag），直接解析、无需令牌
-pnpm typecheck    # tsc --noEmit
-pnpm lint         # eslint .（flat config：js + typescript-eslint + react-hooks recommended）
-pnpm build        # → lib/index.js + lib/invariant.js + lib/client.js + lib/client-registry.js + lib/types
-pnpm test         # vitest（含 manifest 一致性守卫，需先 build）
-pnpm watch        # tsdown --watch
-```
-
-**Make 薄封装**（`make help` 查看全部目标；package.json 仍是唯一事实源）：
-
-```sh
-make check          # 聚合校验门禁：typecheck → build → test → check:consumer-types（对齐 CI）
-make mount          # 真机挂载冒烟：build + pack → 安装 Chromium → pnpm test:mount
-make clean          # 清理 lib/、*.tgz、playwright-report/、test-results/
-```
-
-`pnpm check:consumer-types`：对外类型声明面守卫——以浏览器-only 消费者（无 `@types/node`、`skipLibCheck: false`）的视角对构建出的 `lib/types` 做类型检查，需先 `pnpm build`。
-
-**架构**：单 npm 包、host/client 双半结构——host（`src/index.ts`）：`/sidebar/api/*` JSON API、`/sidebar/file` 媒体路由、`/sidebar/html` 预览路由、`/sidebar/upload` 上传路由，以及两条 WebSocket（`/sidebar/ws/agent-opens` 模型打开推送、`/sidebar/ws/fs-watch` 文件树目录 watch；fs / git / 预览全部会话级 + 信任围栏）；client（`src/client/index.tsx`）：portal 侧边栏 + 各视图 + 链接接管；状态按会话持久化 localStorage。插件按 DSH 官方规范组织（无 default 导出、双 client bundle），运行期不依赖 npm / checkout（`@deepseek-ai/*` 由 web profile 提供）。
-
-## 🔐 安全
-
-- 路由受 Host 头信任围栏保护（与 `/api` 一致）；`fs.write` 原子写入；媒体/预览路由仅限会话 cwd 内文件（`workspaceFence` 关掉时除外，见设置页）；git 只调 CLI、绝不设置身份
-- HTML 预览的内容在**不透明源沙箱 iframe** 中渲染（无 `allow-same-origin`/`allow-top-navigation`、`no-referrer`、权限策略全禁）；`/sidebar/html` 路由带 CSP `sandbox` + 大小/路径边界
-- 设置页可按功能关闭 HTML 预览的沙箱（`htmlViewerNoSandbox` / `htmlViewerDefaultUnsafe`，默认关闭，带警告文案）——关闭后内容与界面同源，仅建议对完全可信内容使用。**网页 tab 的沙箱不再是插件的面**：浏览器视图由宿主提供（desktop profile），其沙箱与导航策略见 DSH 侧文档
-
-## ⚠️ 已知限制
-
-- Git 无 push/pull/fetch；Markdown 预览提供手动刷新按钮，刷新未保存编辑前会确认是否丢弃草稿；文件树只对**已展开**的目录做 watch（折叠的目录不订阅，也不做全工作区递归扫描）；工具行内文件打开按钮不可拦截
-- **只读预览的格式由宿主决定**：表格 / PDF / 图片 / Office 走 DSH 自己的 `ui-sidebar-documentpreview`，插件只渲染 Markdown / HTML 与可编辑的文本代码；宿主的实现（渲染细节、缩放、刷新时机）随 DSH 版本走
-- **浏览器视图只在 desktop profile 存在**：Web profile 没有宿主 `browser` kind，插件也不再自带浏览器 tab，因此网页 tab 只在 desktop profile 可用；登录态 / 第三方 Cookie / `X-Frame-Options` 等限制随宿主实现
-- HTML 预览渲染的是已保存文件（不反映未保存草稿）
-- 移动端（<768px）无底部面板：进入窄屏时其标签页一次性并入右侧栏（迁移后回桌面仍保留在右侧栏），桌面端的底部面板只在宽视口下可用。未选中会话时，点按弱化开关会显示选择会话提示；选中会话后开关打开全宽抽屉
-
-## 🖥️ 平台支持
-
-Windows / Linux / macOS 三平台适配（macOS 日常验证；其余经单元测试覆盖）。插件不再包含原生依赖（终端与 `node-pty` 已整体交还 DSH 自身），构建只需 Node + pnpm，无需编译工具链。

-> **Built on DSH's native sidebar API** (since v0.19.0): the right column *is* DSH's own sidebar — every plugin tab type and tab body registers and opens through `ctx.sidebarRightTabs` / `ctx.sidebarRight`, every file open from the chat goes through `ctx.sidebarRight.openResource('dsh-resource://file/…')`, and the plugin **no longer draws a right panel of its own** (the old free-window capability is gone with it). The self-drawn bottom workbench and the `ctx.betterSidebar` service other plugins register against are unchanged — see the [plugin integration guide](docs/external-plugin-guide.md).

 ## ✨ Features
 
-- **🗂️ File Workbench**: file explorer (lazy-loading tree whose **expanded directories the host watches per directory, re-listing them whenever they change**; symlinks show their target kind — directory links expand, dangling links flagged; per-extension icons on tree rows and file tabs — markdown / images / PDF / code / config / archives — plus plugin-registered ones via `registerFileIcon`) + an **editable** CodeMirror editor; Markdown (incl. Mermaid diagrams, strict-mode safe rendering + click-to-zoom; README-level inline HTML — badge walls / `<details>` blocks / inline tags in table cells, DOMPurify-sanitized; floating table of contents) and HTML (sandboxed iframe plus the two escape hatches the host does not have) are still rendered by this plugin
-- **🌐 Browser and document preview (provided by DSH)**: web tabs are the host's own `ui-sidebar-browser` (multiple tabs, back / forward / reload, sandboxed iframe — **desktop profile only since 0.1.7**); spreadsheets / PDF / images / Office are the host's own `ui-sidebar-documentpreview` (host-side Office→PDF conversion, worker-backed spreadsheet tables, image / PDF zoom viewports, per-directory auto-refresh). The plugin **no longer claims** those formats and keeps only the half the host does not provide: the **external-link takeover** — only links a tab type explicitly claims through `urlTarget`, everything else is let through to the host (whose `linkOpening` user setting decides where prose links go)
-- **💻 Terminal (provided by DSH)**: the right-Sidebar terminal is provided by DSH's own `ui-sidebar-terminal` (shell picker, rename, reconnect, restore after reload, theme following). The plugin no longer ships a terminal of its own
-- **📂 Model-driven sidebar opens (opt-in)**: with the global setting on, the `sidebar_open` tool lets the model actively open files / folders (tree rooted there) / HTTP(S) pages in the sidebar (a web tab needs the host's `browser` kind, i.e. the desktop profile)
-- **🌿 Changes**: one tab, two lenses — **Git** (real diff / history / stage·commit·revert / worktree & child-repo selection) and **This Session** (live tracking of every file the model reads / writes / edits, grouped by file with kind filters); a unified diff renderer (mod pairing + intra-line character highlights + syntax coloring incl. mjs/cjs/mts/cts, CSS/SCSS/Less, HTML/XML/SVG/Vue, GraphQL, JSONC/JSON5 + context folding), a draggable bottom preview pane, and one-click expansion into a dedicated diff tab; `.md` ops (read / write / edit) offer a **reading-mode** toggle in the preview header — the shared MarkdownText renders GFM tables / task lists / strikethrough / footnotes / math, with local images rewritten through the /sidebar/file media route; documents with ```mermaid fences render through the editor's lazy mermaid renderer (click-to-zoom / pan diagrams); **secret redaction** — credential-shaped paths mask whole files and ordinary files mask secret-shaped values (api_key: / Bearer / sk- / AKIA / ghp_ / PEM …, field names kept), on by default with a one-click preview-pane toggle (persisted in localStorage), display-only — session data untouched. Known edge: an unquoted mermaid label containing a redacted secret breaks the diagram (falls back to source); workaround: quote the label. `.html` ops (read / write / edit) gain a **Render** toggle in the preview head — the editor's `/sidebar/html` route iframe, with relative assets resolving inside the route and segmented reads rendering the full document; always sandboxed (opaque origin + CSP header, no escape hatch). `.pdf` ops (read / write / edit) gain the same **Render** toggle — the editor's PDF preview reused verbatim (media-route bytes + explicit Blob, the browser's native viewer inline, with a download fallback)
-- **🧩 Background Tasks**: agent topology + background tasks (exit codes / live output / force-kill)
-- **💬 Side Chat (beta)**: Codex-style side threads — the child inherits the parent's FULL context (completed turns + the pending question + the in-progress turn's assistant output and tool activity, honestly frozen as "interrupted") and runs independently without entering the main conversation; threads support continuous follow-ups (auto-resumed after a DSH restart) and one-click "Save as new session" promotion to a top-level session
-- **🖥️ Native right sidebar + plugin bottom workbench**: the right column belongs to DSH's native right sidebar — the plugin registers every tab type as a native tab (file opens go through `dsh-resource://file/**`, and the built-in Files page / file tree is taken over), keeping only its own bottom workbench (split panes / session persistence) whose toggle sits in the session header
-- **🔁 Session Isolation**: layout / tabs / panels persisted per session, stale state auto-purged
-- **⚙️ Declarative Settings**: per-item toggles in the "Side Cards" settings section, secondary settings via the gear dialog
-- **⚡ On-demand Loading**: only ~325KB core at startup; heavy deps (editor / mermaid diagrams / third-language dictionaries) load on demand ([design](docs/plans/2026-08-12-lazy-chunks-design.md))
-- **🌏 i18n**: UI text follows DSH's language (zh / en) with live switching; with the optional `@huanlin/dsh-plugin-better-locale` peer, 19 third-language overlays (ja / de / fr / …) are available
+What this plugin adds on top of DSH's stock sidebar:
 
-> 🔌 **Core principle**: service-first — the 5 built-in tabs + 3 viewers register through the same `ctx.betterSidebar` API as third-party plugins, with fully equal capabilities; anything the ecosystem can provide better is delegated to ecosystem plugins (**28+ ecosystem plugins** already — see "🌐 Plugin Ecosystem" below). See "🔌 Service API" and the [external plugin guide](./docs/external-plugin-guide.md).
+- **✏️ Editable editor**: the host's document preview is **read-only** → the plugin keeps an **editable** CodeMirror editor (save, syntax highlighting, preview toggle); Markdown / HTML also render through the plugin's own pipeline (Mermaid diagrams with safe rendering + click-to-zoom, README-level inline HTML, floating table of contents, sandboxed HTML preview)
+- **🗂️ Enhanced file tree**: takes over the built-in Files page — lazy-loading tree, **expanded directories watched live and auto-refreshed**, symlink awareness, global filename search, drag-and-drop upload, hover `@file` to drop a reference into the input box
+- **🌿 Changes** (no Git panel in the stock sidebar): two lenses in one tab — **Git** (diff / history / stage·commit·revert) and **This Session** (every file the model touched) — with a unified diff renderer (intra-line character highlights, syntax coloring, secret redaction)
+- **🧩 Background Tasks** (absent upstream): agent topology preview + background task list (exit codes / live output / force-kill)
+- **💬 Side Chat** (absent upstream, beta): Codex-style side threads — inheriting the full parent context, running independently, promotable to a top-level session
+- **🖥️ Bottom workbench** (absent upstream): the right column belongs to DSH's native right sidebar; the plugin adds its own bottom workbench (drag-to-split panes, per-session persistence) that coexists with the native bar
+- **📂 Model-driven sidebar opens (opt-in)**: the `sidebar_open` tool lets the model actively open files / folders / web pages in the sidebar
+- **🔌 Service API**: `ctx.betterSidebar` is open to every plugin (`registerTab` / `registerFileViewer`); the built-in 5 tabs + 3 viewers go through the same API, and **28+ ecosystem plugins** already build on it (see "🌐 Plugin Ecosystem")
+- **⚡ On-demand loading**: ~325KB core at startup, editor / Mermaid / third-language dictionaries load on demand · **🌏 i18n** follows DSH's language · **🔁 Session isolation** persists layout per session

+
+### v0.21.1
+
+> 📦 **Stable release** (npm `latest`): supports **DSH 0.1.7-rc.1+** only (peer floor `^0.1.7-rc.1`, CI pins `@deepseek-ai/dsh@0.1.7-rc.1`). **Hosts on DSH 0.1.6-alpha.2 or earlier should stay on v0.19.1** — 0.1.7 moves three hard contracts (the settings service, the icon named exports and the session format) and this version writes no runtime compatibility layer. ⚠️ **The previous v0.20.0 was never published to npm**: its terminal / browser handover ships here too, so npm goes straight from 0.19.1 to this version.
+
+- 🗂️ **Read-only file previews handed to DSH's document preview**: DSH 0.1.7's `ui-sidebar-documentpreview` ships its own spreadsheet / PDF / image / Office rendering (host-side Office→PDF conversion, worker-backed spreadsheet tables, image / PDF zoom, per-directory auto-refresh), so the plugin deleted its `image` / `pdf` / `binary-download` viewers and **refuses** those extensions in `editor.canOpen` — `xlsx xls csv tsv fods pdf png jpg jpeg gif webp svg bmp ico doc docx ppt pptx` — handing the address back to the host. **rc.1 takes nine of them back**: `xlsb` / `xlt` / `xltx` / `xltm` / `ots` / `dot` / `dotx` / `avif` / `ods` have **no host renderer at all** (opening one only said "preview is not available"), yet before the handover they reached the plugin's download pane — a regression we introduced ourselves in the previous version. The plugin's `code` catch-all claims them again. `fods` stays handed over (the host shows that flat XML as plain text, which beats a download pane). — handing the file address back to the host. **Three things the host does not have stay in the plugin**: Markdown (its own renderer), HTML (its own sandboxed preview plus the `htmlViewerNoSandbox` / `htmlViewerDefaultUnsafe` safety switches), and the **editable** text / code editor (the built-in ones are read-only previews); unknown binaries (`.zip` / `.wasm`) still land on the code editor's download pane after the binary check, so nothing regresses.
+- 🔗 **External-link takeover narrowed**: the three protocol-routing external-link settings are gone (with their keys in all 20 locale dictionaries). The plugin now takes over **only links a tab type explicitly claims through `urlTarget`** and lets everything else through for the host to route (DSH 0.1.7 adds the user setting `linkOpening`, deciding whether prose links open in the sidebar or a new tab); **when nothing claims a link it does not preventDefault**; a successful claim whose target type is unavailable at open time falls back to `window.open(url, '_blank', 'noopener,noreferrer')` — which also fixes a real regression from the previous version: http links inside plugin-drawn markdown (Side Chat transcripts / editor previews / diff panes) did nothing when clicked. Separately, the host's `browser` kind is **no longer mounted in the Web profile** (0.1.7 mounts it in the desktop profile only).
+- ⚙️ **Settings surface rewritten + preferences imported automatically**: DSH 0.1.7 removed the registrable settings namespace in favour of **looking a form up by the plugin Loader row's entry id** (`SettingsForms`: only `describe` / `update` / `replace` / `mutate` / `configure` remain). Plugin preferences therefore live in the **profile's cordis patch document** (i.e. this plugin's mount row), not in `~/.dsh/settings.yaml`; the schema comes from the plugin module's exported `Config` (this version merges the user preferences into `Config` and marks every preference field `meta.volatile = true` — **that single flag is the entire "settings apply live, without remounting the plugin" mechanism**). **Your settings are not lost**: on first boot the plugin imports the `dsh-better-sidebar` section of the old `settings.yaml` / `settings.yaml.imported` once (only while that row still has no user values, and only fields the current schema still declares). The entry id is **discovered at runtime** (this bundle defaults to `better-sidebar`; an aggregate bundle mounts it under a different id) and never hardcoded.
+- 🔄 **Live-refreshing file tree**: the plugin takes over the built-in Files page, so the host's own per-directory watch cannot cover that tree — this version adds `/sidebar/ws/fs-watch`: the client reports the directories it has **expanded**, the host watches exactly those with `fs.watch` (150ms debounce, a 64-handle cap per connection, paths going through the same workspace fence as `fs.tree`), and a change re-lists just that level; collapsing unsubscribes. Before this, the tree stayed stale until a manual refresh.
+- 🐛 **Session following fixed**: the plugin used to read a **non-existent `SessionListState.current` field** (its own type mirror invented it, so the compiler never complained), which meant per-session persistence was never actually bound and the narrow-viewport park gate was always false. It now uses DSH 0.1.7's `ctx.sidebarRight.mounted` (set only when the column really switches to another session).
+- 🖥️ **The model-side cost is unchanged**: the plugin's own 8 `terminal_*` tools (off by default) were already removed in the previous version, and the upstream equivalent `@deepseek-ai/dsh-tool-terminal` is **still not mounted by any shipped bundle** — add a `tool-terminal` row to your profile's `cordis.patch.yml` when you need a persistent terminal (otherwise the model only has one-shot `bash` / `pwsh`).
+- 📐 **Baseline**: every `@deepseek-ai/dsh-*` pins `0.1.7-rc.1`, with the `@deepseek-ai/cordis` peer floor at `^4.0.3`; `ui-primitives` renamed its whole family of named icon exports (`Icon<Name><14|16>` → `Icon<Name>Regular` / `Medium`, 26 named imports adapted); session format v3→v4 (the Side Chat boundary injection now uses `plugin:dsh-better-sidebar`, and tool-result messages use the top-level `role: 'tool'` shape, with parsers accepting both old and new shapes for historical logs).

+## 🔌 Service API
+
+Since v0.4.0 the plugin exposes the `ctx.betterSidebar` service — other plugins can register sidebar pages and file viewers (the 5 built-in tabs + 3 viewers register through the same service). v0.12.1 completed the base capabilities (complete type exports, capability detection, state subscription, tab badges, lifecycle callbacks, targeted open, plugin-owned settings, etc.).
+
+Full integration docs (complete fields, matching algorithm, HMR pitfalls, declarative settings, version detection, the native-sidebar surface and the skinning contract): **[`docs/external-plugin-guide.md`](./docs/external-plugin-guide.md)**; repository rules (hard constraints / CI / release) live in [`AGENTS.md`](./AGENTS.md).
+
+### ➕ Add Plugins (recommended plugin catalog)
+
+The dashed cards at the end of the "Sidebar content" / "File viewers" grids in the "Side Cards" settings section open the **Add tab plugins** / **Add preview plugins** modals: each declares its open extension point, offers a "**Browse more plugins on GitHub**" button (the [GitHub topic `dsh-better-sidebar`](https://github.com/topics/dsh-better-sidebar)), and lists the recommended catalog (name / repo / description / install script) — "**Open**" jumps to the repo, "**Copy**" writes the install command to the clipboard.
+
+**Curating a new plugin**: append a `PluginEntry` to [`src/client/plugins-tabs.ts`](./src/client/plugins-tabs.ts) (tab registrations) or [`src/client/plugins-viewers.ts`](./src/client/plugins-viewers.ts) (file-previewer registrations) and tag your repo with the `dsh-better-sidebar` topic; data integrity is guarded by `tests/plugin-list.spec.ts`.
+
+## 🛠️ Development & Build
+
+```sh
+pnpm install      # @deepseek-ai/* devDependencies resolve (baseline 0.1.7-rc.1, alpha dist-tag) — no token needed
+pnpm typecheck    # tsc --noEmit
+pnpm lint         # eslint . (flat config: js + typescript-eslint + react-hooks recommended)
+pnpm build        # → lib/index.js + lib/invariant.js + lib/client.js + lib/client-registry.js + lib/types
+pnpm test         # vitest (includes manifest consistency guard; build first)
+pnpm watch        # tsdown --watch
+```
+
+**Make thin wrappers** (`make help` lists every target; package.json stays the single source of truth):
+
+```sh
+make check          # aggregate gate: typecheck → build → test → check:consumer-types (mirrors CI)
+make mount          # real-mount smoke: build + pack → install Chromium → pnpm test:mount
+make clean          # remove lib/, *.tgz, playwright-report/, test-results/
+```
+
+`pnpm check:consumer-types`: the consumer-facing declaration-surface guard — type-checks the built `lib/types` from a browser-only consumer's perspective (no `@types/node`, `skipLibCheck: false`); run `pnpm build` first.
+
+**Architecture**: a single npm package with host/client halves — host (`src/index.ts`): `/sidebar/api/*` JSON API, `/sidebar/file` media route, `/sidebar/html` preview route, `/sidebar/upload` upload route, and two WebSockets (`/sidebar/ws/agent-opens` for model-driven opens, `/sidebar/ws/fs-watch` for the file tree's directory watch; fs / git / preview are all session-scoped behind a trust fence); client (`src/client/index.tsx`): portal sidebar + views + link takeover; state persisted per session in localStorage. Organized per DSH official conventions (no default export, dual client bundles); no dependency on npm / checkout at runtime (`@deepseek-ai/*` provided by the web profile).
+
+## 🔐 Security
+
+- Routes protected by a Host-header trust fence (same as `/api`); `fs.write` is atomic; media/preview routes only serve files inside the session cwd (unless `workspaceFence` is turned off in settings); git only shells out to the CLI and never sets identity
+- HTML preview content renders in an **opaque-origin sandboxed iframe** (no `allow-same-origin`/`allow-top-navigation`, `no-referrer`, all permission policies disabled); the `/sidebar/html` route carries a CSP `sandbox` + size/path bounds
+- The settings page can disable the HTML preview's sandbox per feature (`htmlViewerNoSandbox` / `htmlViewerDefaultUnsafe`, off by default, with a warning) — when off, content shares the origin with the UI; only recommended for fully trusted content. **The web tab's sandbox is no longer this plugin's surface**: the browser view comes from the host (desktop profile); see DSH's own docs for its sandbox and navigation policy
+
+## ⚠️ Known Limitations
+
+- Git has no push/pull/fetch; Markdown previews provide a manual refresh button with confirmation before discarding unsaved edits; the file tree only watches **expanded** directories (collapsed folders are unsubscribed, and there is no recursive whole-workspace scan); tool inline file-open buttons cannot be intercepted
+- **Which read-only previews exist is the host's call**: spreadsheets / PDF / images / Office go to DSH's own `ui-sidebar-documentpreview`, while the plugin renders only Markdown / HTML and the editable text buffer; the host implementation (rendering details, zoom, refresh timing) follows the DSH version
+- **The browser view exists only in the desktop profile**: the Web profile has no host `browser` kind and the plugin no longer ships a browser tab, so web tabs are desktop-only; login state / third-party cookies / `X-Frame-Options` limits follow the host implementation
+- HTML preview renders the saved file (not unsaved drafts)
+- No bottom panel on mobile (<768px): on narrow screens its tabs merge into the right sidebar once (after migrating back to desktop they stay in the right sidebar); the desktop bottom panel is only available on wide viewports. Without a selected session, tapping the subdued toggle shows the select-session message; with a selected session, it opens the full-width drawer
+
+## 🖥️ Platform Support
+
+Windows / Linux / macOS (macOS validated daily; the rest covered by unit tests). The plugin carries no native dependencies (the terminal and `node-pty` went back to DSH wholesale), so building needs only Node + pnpm, with no compiler toolchain.

-> 🧪 **alpha channel** (npm dist-tag `alpha`, install `dsh-better-sidebar@latest`; npm `latest` is still **v0.19.1**): supports **DSH 0.1.7-rc.1+** only (peer floor `^0.1.7-rc.1`, CI pins `@deepseek-ai/dsh@0.1.7-rc.1`). **Hosts on DSH 0.1.6-alpha.2 or earlier should stay on v0.19.1** — 0.1.7 moves three hard contracts (the settings service, the icon named exports and the session format) and this version writes no runtime compatibility layer. ⚠️ **The previous v0.20.0 was never published to npm**: its terminal / browser handover ships here too, so npm goes straight from 0.19.1 to this version.
-
-- 🗂️ **Read-only file previews handed to DSH's document preview**: DSH 0.1.7's `ui-sidebar-documentpreview` ships its own spreadsheet / PDF / image / Office rendering (host-side Office→PDF conversion, worker-backed spreadsheet tables, image / PDF zoom, per-directory auto-refresh), so the plugin deleted its `image` / `pdf` / `binary-download` viewers and **refuses** those extensions in `editor.canOpen` — `xlsx xls csv tsv fods pdf png jpg jpeg gif webp svg bmp ico doc docx ppt pptx` — handing the address back to the host. **rc.1 takes nine of them back**: `xlsb` / `xlt` / `xltx` / `xltm` / `ots` / `dot` / `dotx` / `avif` / `ods` have **no host renderer at all** (opening one only said "preview is not available"), yet before the handover they reached the plugin's download pane — a regression we introduced ourselves in the previous version. The plugin's `code` catch-all claims them again. `fods` stays handed over (the host shows that flat XML as plain text, which beats a download pane). — handing the file address back to the host. **Three things the host does not have stay in the plugin**: Markdown (its own renderer), HTML (its own sandboxed preview plus the `htmlViewerNoSandbox` / `htmlViewerDefaultUnsafe` safety switches), and the **editable** text / code editor (the built-in ones are read-only previews); unknown binaries (`.zip` / `.wasm`) still land on the code editor's download pane after the binary check, so nothing regresses.
-- 🔗 **External-link takeover narrowed**: the three protocol-routing external-link settings are gone (with their keys in all 20 locale dictionaries). The plugin now takes over **only links a tab type explicitly claims through `urlTarget`** and lets everything else through for the host to route (DSH 0.1.7 adds the user setting `linkOpening`, deciding whether prose links open in the sidebar or a new tab); **when nothing claims a link it does not preventDefault**; a successful claim whose target type is unavailable at open time falls back to `window.open(url, '_blank', 'noopener,noreferrer')` — which also fixes a real regression from the previous version: http links inside plugin-drawn markdown (Side Chat transcripts / editor previews / diff panes) did nothing when clicked. Separately, the host's `browser` kind is **no longer mounted in the Web profile** (0.1.7 mounts it in the desktop profile only).
-- ⚙️ **Settings surface rewritten + preferences imported automatically**: DSH 0.1.7 removed the registrable settings namespace in favour of **looking a form up by the plugin Loader row's entry id** (`SettingsForms`: only `describe` / `update` / `replace` / `mutate` / `configure` remain). Plugin preferences therefore live in the **profile's cordis patch document** (i.e. this plugin's mount row), not in `~/.dsh/settings.yaml`; the schema comes from the plugin module's exported `Config` (this version merges the user preferences into `Config` and marks every preference field `meta.volatile = true` — **that single flag is the entire "settings apply live, without remounting the plugin" mechanism**). **Your settings are not lost**: on first boot the plugin imports the `dsh-better-sidebar` section of the old `settings.yaml` / `settings.yaml.imported` once (only while that row still has no user values, and only fields the current schema still declares). The entry id is **discovered at runtime** (this bundle defaults to `better-sidebar`; an aggregate bundle mounts it under a different id) and never hardcoded.
-- 🔄 **Live-refreshing file tree**: the plugin takes over the built-in Files page, so the host's own per-directory watch cannot cover that tree — this version adds `/sidebar/ws/fs-watch`: the client reports the directories it has **expanded**, the host watches exactly those with `fs.watch` (150ms debounce, a 64-handle cap per connection, paths going through the same workspace fence as `fs.tree`), and a change re-lists just that level; collapsing unsubscribes. Before this, the tree stayed stale until a manual refresh.
-- 🐛 **Session following fixed**: the plugin used to read a **non-existent `SessionListState.current` field** (its own type mirror invented it, so the compiler never complained), which meant per-session persistence was never actually bound and the narrow-viewport park gate was always false. It now uses DSH 0.1.7's `ctx.sidebarRight.mounted` (set only when the column really switches to another session).
-- 🖥️ **The model-side cost is unchanged**: the plugin's own 8 `terminal_*` tools (off by default) were already removed in the previous version, and the upstream equivalent `@deepseek-ai/dsh-tool-terminal` is **still not mounted by any shipped bundle** — add a `tool-terminal` row to your profile's `cordis.patch.yml` when you need a persistent terminal (otherwise the model only has one-shot `bash` / `pwsh`).
-- 📐 **Baseline**: every `@deepseek-ai/dsh-*` pins `0.1.7-rc.1`, with the `@deepseek-ai/cordis` peer floor at `^4.0.3`; `ui-primitives` renamed its whole family of named icon exports (`Icon<Name><14|16>` → `Icon<Name>Regular` / `Medium`, 26 named imports adapted); session format v3→v4 (the Side Chat boundary injection now uses `plugin:dsh-better-sidebar`, and tool-result messages use the top-level `role: 'tool'` shape, with parsers accepting both old and new shapes for historical logs).
-
-### v0.20.0 (dev line, **never published**)
-
-> 🚫 **This version never reached npm** (npm `latest` is still v0.19.1): it was meant to be the stable release on the 0.1.6-alpha.2 line, but the 0.21 line replaced it before release, so everything below actually shipped in **v0.21.1**. Its original positioning: supports **DSH 0.1.6-alpha.2+** only (peer floor `^0.1.6-alpha.2`, CI pins `@deepseek-ai/dsh@0.1.6-alpha.2`). **This is a breaking-change release**: hosts on 0.1.5-rc.* should pin `dsh-better-sidebar@0.19.1`. See [docs/plans/2026-09-21-dsh-0.1.6-alpha.2-adaptation.md](docs/plans/2026-09-21-dsh-0.1.6-alpha.2-adaptation.md) for the adaptation record.
-
-- 🖥️ **Terminal handed to DSH's built-in**: DSH 0.1.6 ships its own right-column terminal (`ui-sidebar-terminal`), so the plugin deleted its whole terminal stack — `pty-manager` / `agent-pty` / `pty-deps` / the 8 `terminal_*` tools / the xterm view and font-linking / cross-session terminal pinning — along with the `node-pty` dependency, its `allowBuilds` grant and the installer's `-Repair` mode. **Note**: the model therefore loses a cross-call persistent terminal (only one-shot `bash` / `pwsh` remain); the upstream `@deepseek-ai/dsh-tool-terminal` is not mounted by any shipped bundle, so enable it yourself in the profile when you need it.
-- 🌐 **Browser view handed to the built-in**: the plugin deleted `BrowserView` / the sandbox status bar / the embeddability probe (including the host's `browser.probe` route) and the two settings that only configured its own iframe; it **keeps** the external-link takeover in the chat and UI (protocol-based routing is the capability the host does not have), now targeting DSH's built-in `browser` tab type.
-- 🧩 **The produced-files row goes back to the host**: DSH 0.1.6 turned `conversation.chat.turnTail` from a chain into a list (upstream deliberately lets several plugins **append** rather than replace each other), so the plugin's takeover could only duplicate the built-in deliverables card and was removed wholesale; click behaviour is unchanged (the built-in goes through the host's `openFile` → this plugin's editor). The cost is the one "reveal in the file tree" entry at the turn tail (the in-tree context menu remains).
-- 🐛 **Two silent breakages fixed**: once `SidebarRightGuideEntry.id` became required, a missing id left the **whole native surface silently empty** (the throw happens inside an `ctx.inject` callback and is swallowed); once `turnTail` became a list the old registration threw outright and the row died. Both are fixed and guarded by tests, with a registration-failure reporting hook added alongside.
-- 🎨 **The empty-pane card now matches the built-in card recipe**: `.paneCard` adopts DSH's guide-capsule recipe (0.5px l4 border / 24px radius / layer-1 fill / 56px minimum / 14×20 padding), with tests guarding its geometry, its tokenized colours, and that it does not copy upstream's **undefined** `--dsw-alias-bg-l1/-l2` spellings.
-- 📐 **Baseline**: every `@deepseek-ai/dsh-*` package is pinned to `0.1.6-alpha.2`, the vanished `dsh-code-runtime` package is removed, `diff` / `simple-icons` are hoisted into devDependencies as primitives' new bare imports, and `ui-primitives`' three breakages this release (`IconSendOutline16` gone, `TerminalBlockLabels.noExitCode` added, `ConnectionIndicator.reconnectLabel` removed) are adapted.
-
-### v0.19.1
-
-> 📌 **Stable release** (npm `latest`, no prerelease suffix): the pinned baseline moves to **DSH 0.1.5-rc.2** (npm `next`) while the **peer floor stays `^0.1.5-rc.1`** — nothing in the rc.2 upstream delta touches this plugin (zero changes under `packages/api|host|session|agent`; the only real code edits are the message-feedback dialog, deliverables card CSS and the `CodeFileIcon` SVG data split), so rc.1 hosts need no DSH upgrade to run this version. Hosts on DSH 0.1.5-alpha.2 stay on **v0.19.0-alpha.1**; the 0.1.2-rc.1 stable line keeps using **v0.18.1**.
-
-- 🎯 **Adapted to DSH 0.1.5-rc.2**: devDependency pins, the CI mount lane and `SIDEBAR_SERVICE_VERSION` all move to rc.2; there is **no plugin-side code change** (the upstream delta does not touch this plugin — file-by-file audit in [docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md](docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md): the vast majority of the 300 changed files are single-line `version` bumps).
-- 🎨 **File icons (#611) and the built-in tab glyphs are now colored** (#531 + #594 merged, implementation redone for rc.2):
-  - **Files and folders use DSH's own artwork**: the fallback link is the host's `FileTypeIcon` from `ui-primitives` (48 full-color official code/config glyphs plus the category-colored sheets for markdown, images, PDF, Office, video and folders), so the plugin **ships no extension table and needs no icon chunk** — #429's 563-entry color dataset and `lib/client-file-icons.js` (255 kB) are gone, along with the `fileIconTheme` switch. Color is simply the behaviour now, and the core bundle grew by 10 kB.
-  - **New public `registerFileIcon` API** (capability `'fileIcons'`): register your own glyphs by extension (`exts`), exact file name (`names`) or directory name (`folderNames`), ranked by priority then registration order. **Caveat**: the host classifier covers every path, so a catch-all (`exts: []`) claims every row the specific rules miss.
-  - **Colored built-in tab glyphs**: Files / Changes / Tasks / Side chat / Terminal / Browser and the diff view all get a colored glyph, painted from `--dsw-alias-*` tokens so every skin still applies.
-  - **The native right Sidebar's tab chips carry a glyph too**: the host's tab definition has no icon field, but the `sidebar.right.pane.tab.title` slot *is* the chip's content — the plugin renders `[glyph][title]` there (an editor tab with a path shows that file's icon). The glyph is `aria-hidden`, so the chip's accessible name is unchanged.
-- 🛠 **CI fix 1: real Windows-lane timeouts**. `ci-windows` went red eight times in the 2026-09-09/10 window; six of those were process-spawning cases hitting vitest's 5000 ms default: `tests/agent-pty.spec.ts` (real PowerShell + ConPTY per terminal) and `tests/install-powershell.spec.ts` (a cold `powershell.exe` start measured 12.1 s) now declare a 30 s budget each, vitest.config.ts raises the global `testTimeout` from its 5000 ms default to **15 s** (the first real Windows run then lost a *third* file to the same default — `tests/git.spec.ts:85` at 9607 ms; three files, one cause, so per-file patches were whack-a-mole), and `waitForTranscript`'s inner poll budget dropped from 5000 ms to 15 s — **the inner budget must sit below the outer one** (they used to be the same 5000 ms, a structurally guaranteed timeout). `ci-windows`'s `Test` step now runs `pnpm test:windows` (`--maxWorkers=2`) so the process-spawning specs stop starving each other on a 2-core runner.
-- 🛠 **CI fix 2: the mount lane's npm install**. `plugin-mount`'s `npm install -g @deepseek-ai/dsh@<ver>` failed four times (two `ETARGET`, two `JavaScript heap out of memory` / exit 134): the pinned version declares its transitives as floating `^` ranges, so while upstream publishes a prerelease in stages (rc.2 appeared package by package between 14:43 and 14:57 UTC on 09-10) npm resolved a mixed rc.1/rc.2 peer graph (3062 ERESOLVE lines). The lane now pins an **already-complete** rc.2 (fixes ETARGET) and passes `NODE_OPTIONS=--max-old-space-size=4096` (fixes the OOM). `--legacy-peer-deps` was tried on the way and rejected by real CI: it skips exactly the peers a global install must supply, and `@deepseek-ai/cordis-plugin-group` — required at boot by `dsh-app-boot` — is a peer rather than a dependency, so the CLI died with `ERR_MODULE_NOT_FOUND`.
-
-### v0.19.0
-
-> 📌 **Stable release** (npm `latest`, no prerelease suffix): supports **DSH 0.1.5-rc.1+** only (peer floor `^0.1.5-rc.1`, CI pins `@deepseek-ai/dsh@0.1.5-rc.1`). Hosts on DSH 0.1.5-alpha.2 should stay on **v0.19.0-alpha.1** (the npm `alpha` tag still points there); the 0.1.2-rc.1 stable line keeps using **v0.18.1**.
-
-**✨ New**
-
-- 📝 **The new-tab list gets an optional description back**: DSH 0.1.5-rc.1 restored `SidebarRightGuideEntry.description` (optional), so the plugin restores `TabDescriptor.description` — each of the six built-in types declares a line again (all six guide rows — Files / Changes / Tasks / Side chat / Terminal / Browser — carry one), and the `guideDesc*` keys return to all 20 dictionaries. **The host's native guide renders descriptions only while the listed entries are ≤ 4** (a longer list drops every description rather than truncating), and the plugin contributes six guide entries by default — so in the default composition no description is rendered; they appear once the reader disables enough tab types (per-type switches live on the plugin's settings page) to bring the guide down to four entries or fewer. An entry that declares none stays a single icon + title line (the plugin ships no generic fallback sentence). (#613)
-
-**🐛 Fixes**
-
-- None. The rc.1 delta over alpha.2 is small (373 changed files, overwhelmingly upstream package version bumps, native-sidebar preview UI polish, and test snapshots); apart from the restored description field (plus upstream's `files` type now using its own coloured folder glyph as the guide glyph) nothing needed adapting.
-
-**🧰 CI & internals**
-
-- Baseline moved to **DSH 0.1.5-rc.1+** (#613): peer floor, devDependency pins, the CI mount lane, and `dsh.plugin.json`'s `engines.dsh` all follow (rc.1 is both the `latest` and `next` dist-tag on npm).
-- Explicitly unchanged, no need to re-check: the global main-panel model (the `main` slot / `sidebar.panellist` / `ctx.layout` / root-scoped `rightbar` + `rightbar.session`, still not adopted), the file address grammar (`packages/util/workspace-path` only had its version bumped), the native tab-body host contract (`.paneBody` is still a block scroller with a definite height), the core / agent / session / subagent host APIs, and the `ui-primitives` export surface (only CodeBlock rendering changed).
-- `@deepseek-ai/dsh-client-ui-primitives@0.1.5-rc.1` still declares no `dependencies` while its bundle still bare-imports `anser` / `shiki` / `@shikijs/langs/*` / `mdast-util-*` / `micromark-*` / `katex` — the third-party devDependencies hoisted in the previous release therefore stay, and must not be reverted.
-- Real-host verification (DSH 0.1.5-rc.1 + plugin 0.19.0): `typecheck` / `lint` / `check:consumer-types` green; unit suite **124 files · 1296 passed · 9 skipped**; `pnpm peers check` clean; the mount smoke lane against real rc.1 **7 passed** (including the tab-body fill assertion and the new "descriptions render only at ≤4 guide entries" assertion); on the local 3080 instance the guide still shows six icon+title capsules (6 > 4, so upstream renders no descriptions — upstream also raised the capsule `min-height` from 48px to 56px), clicking `AGENTS.md` in the file tree lands in the plugin editor (CodeMirror mounted), the side-chat composer sits on the pane floor (host box 962px == pane body 962px, composer 8px off the bottom), the bottom workbench's edges coincide with the centre column, and `pageerror` is 0 (the only console noise is the third-party `dsh-tauri-worktree` `/api/dsh-worktree/attach` 500, unrelated to this change).
-
-### v0.19.0-alpha.1
-
-> 🧪 **alpha channel** (npm dist-tag `alpha`, install `dsh-better-sidebar@latest`): supports **DSH 0.1.5-alpha.2+** only (peer floor `^0.1.5-alpha.2`, CI pins `@deepseek-ai/dsh@0.1.5-alpha.2`). Stay on **v0.19.0-alpha.0** for 0.1.5-alpha.1; the 0.1.2-rc.1 stable line keeps using **v0.18.1** (npm `latest`).
-
-**✨ New**
-
-- 🪟 **Every tab body now fills its pane** (#609): the native sidebar's tab-body host is a block scroller with a definite height, not a flex container, and the plugin's tab roots declared only `flex: 1` — so they collapsed to content height and the side-chat composer sat right after the transcript instead of at the pane bottom (a long transcript pushed it out of view). The native adapter now wraps every tab body in a `height: 100%` column flex host, restoring the same fill semantics the bottom workbench has for all plugin tabs, third-party `registerTab` descriptors included.
-
-**🐛 Fixes**
-
-- 🧭 **File address grammar follows DSH 0.1.5-alpha.2**: `fileAddressFor` always produces a session-scoped address and absolute paths keep their leading `/`; `parseFileAddress` is prefix-based and ignores `?`/`#` suffixes.
-- 🪟 **Center-column anchor follows alpha.2's global panels**: the `conversation` slot became `main.conversation` under the root-scoped keyed `main` slot, so the locator now resolves the new key and skips `display: contents` slot hosts (alpha.1's old key still works).
-
-**🧰 CI & internals**
-
-- Baseline moved to DSH 0.1.5-alpha.2 (#609): peer floor, 22 devDependency pins, the CI mount lane, and `dsh.plugin.json` engines all follow; `pnpm peers check` is clean (hoisted the `dsh-session-persistence` transitive peer per §3-9).
-- **`TabDescriptor.description` removed**: alpha.2's native guide entries no longer render a second line (they are icon + title capsules), so the field and the six `guideDesc*` keys (20 dictionaries) are gone; a new pane's default page is now selected from the registry (exactly one guide entry opens that page directly).
-
-### v0.19.0-alpha.0

-
-**✨ New**
-
-- 🖥️ **DSH's native right sidebar** (#604): the right column is now DSH's own sidebar — all seven plugin tab types register as native tab types with native tab bodies; every file open from the chat goes through `ctx.sidebarRight.openResource(dsh-resource://file/…)`; the `editor` type claims file resources at `extension` priority (outranking the built-in text preview) and takes over the built-in Files page kind (restored on unregister); cross-session opens queue until the target session is on screen.
-- 🧩 **Own right panel and free windows retired** (#605): with the right column handed back to DSH, the plugin keeps only its bottom workbench (single split tree, per-session persistence) and registers its toggle into DSH's session-header utilities slot; the float API (`floats` / `floatTab` / `dockFloat` / `raiseFloat` / the "Move to Free Window" menu entry), the `'floatWindows'` feature string, and the `openByDefault` / `defaultWidthPercent` / `changesDiffFloat` settings are gone (a persisted `floats` field is ignored, so old documents still load).
-- 🔗 **DSH 0.1.5 host contracts** (#603): the `assistant/chunk` event is gone — live deltas now fold from `agent/assistant-stream` frames (the side chat transcript's `live` field); `sessionPersistence.inspect` is gone — cold reads go through `open(id,'read')`; session headers use `SESSION_FORMAT_VERSION`.
-
-**🐛 Fixes**
-
-- Eight session-event read sites follow the 0.1.5 contracts (side-chat transcript, `jobs.output` replay, fork inheritance); custom seeds now carry the fork marker pair, so they no longer inherit the parent's unclaimed inbox input.
-
-**🧰 CI & internals**
-
-- The real-host mount smoke lane pins 0.1.5-alpha.1 and sweeps the native sidebar's guide page to open every plugin tab type; typecheck / lint / unit tests / mount lane all green.
-
-### v0.18.1
-
-> 📌 **Stable release** (npm `latest`): the DSH baseline is unchanged (**0.1.2-rc.1+**, peer floor `^0.1.2-rc.1`) — this is the incremental cut after v0.18.0: richer op previews in the changes panel, a writable file tree, and five fixes.
-
-**✨ Features**
-
-- 📄 **Op-preview upgrades in the changes panel** (#499): markdown reading mode with mermaid fences, plus inline `.html` and `.pdf` render previews; diff syntax highlighting extended to mjs/cjs/mts/cts, CSS/SCSS/Less, HTML/XML/SVG/Vue, GraphQL, JSONC/JSON5; new **secret redaction** layer (on by default for previews, toggleable in the pane header)
-- 🗂️ **File-tree rename / delete** (#550): inline rename plus confirmed delete, slimmer context menus and viewport-clamped submenus
-- 🧩 **Plugin catalog names and shell preset text localized** (#535): they now follow the host language
-
-**🐛 Fixes**
-
-- 🔀 **Git diff gap folds really expand** (#576, fixes #577): the fold row promised "n lines… click to expand" but did nothing (`-U3` leaves gap segments without row text); the hidden rows now load on demand through `git.show`, sliced from both sides' contents, with loading / failure states and request deduplication — plus a fix to that route's `rev:path` addressing (it always returned empty before)
-- 💬 **Side-chat seeds no longer inherit the parent's unclaimed inbox messages** (#562): the seed carries the fork markers, so the "side chat sends earlier User messages first on long contexts" ghost message is gone
-- 🖼️ **Local images in the split markdown renderer** (#569): rewritten to reachable URLs instead of 404ing

-**🔗 Host track graduation**
-
-- **Onto the DSH 0.1.2 line and graduating to stable**: v0.18.0-alpha.0 dropped the 0.1.1-rc.x compatibility layer and fixed blank Side Chat transcripts on alpha.1+ (#472); the baseline then climbed through alpha.3 (#497) and alpha.5 (#516, `Session.events` → `snapshotEvents()`); the chat file-open funnel moved to `remote.session.openWorkspacePath` (#494) and the "Show in folder" reveal scroll was scoped to the tree body (#453). This release pins the baseline to **DSH 0.1.2-rc.1** (zero source delta vs alpha.5 — a pure version bump; `dsh-client-locale` resumed publishing, everything aligned to rc.1; real-host mount smoke 14/14 in CI)
-
-**✨ Features**
-
-- 🌿 **Unified "Changes" tab** (#475): one tab, two lenses — Git (real diff / history / stage·commit·revert / worktree & child-repo selection) and This Session (live tracking of every file the model reads / writes / edits); a unified diff renderer (mod pairing + intra-line character highlights + syntax coloring + context folding), a draggable bottom preview pane, and one-click expansion into a dedicated diff tab
-- 💬 **Side Chat rendering upgrade** (#486): main-conversation-grade Blocks structure, per-turn usage tails, reconnect banner
-- ⚙️ **Workspace path fence toggle** (#458): a new `workspaceFence` declarative settings key with a one-click off affordance and guidance on 403 error surfaces
-
-**⚡ Performance**
-
-- 🚀 **Core bundle -45%** (#489): 19 non-zh/en dictionary chunks lazy-loaded, render stabilization (transcript row reuse / tree Sets / batched drags), startup & polling cost cuts (single settings fetch, one git process per tick); a new perf measurement lane; also fixes the bottom-pane drag leaking panel width into the host layout and jumping the native left sidebar

-
-> 🧪 **Alpha track**: this release targeted **DSH 0.1.2-alpha.x only** (peer floor `^0.1.2-alpha.5`, npm dist-tag `alpha`). This number was never published separately — its content shipped in the **v0.18.0** stable release, and the same number was later reused for the 0.1.5 adaptation line (see above).
-
-- 🔗 **Adapted to DSH 0.1.2-alpha.5 (published to npm, `alpha` dist-tag)**: the CI mount gate's pin, the `dsh.plugin.json` engines floor, and the `@deepseek-ai/*` peer / devDependencies baseline moved up to 0.1.2-alpha.5 (verified by a real-host mount smoke 14/14). `dsh-client-locale` has no alpha.5 upstream (newest is 0.1.2-alpha.3), so its peer floor / devDep pin trail the baseline and already accept the alpha.5 runtime (`pnpm peers check` reports zero mismatches — no new transitive peers to hoist). The code adapts to alpha.4's compatibility-flagged change — the `Session.events` property was removed, migrated to the on-demand `snapshotEvents()` API (8 sites: sidechat transcript live reads, fork inheritance, `jobs.output` replay, subagent activity), and the `seedLength` meta field the host dropped was removed from thread creation; alpha.4's remaining changes (bidirectional `send_message`, custom-model discovery reusing Profile headers, `SessionSeq`/`SessionLogOffset` strong typing) and alpha.5's upgrade-startup fix were verified not to touch any other plugin surface.
-
-### v0.18.1-alpha.0
-
-> 🧪 **Alpha track**: this release targets **DSH 0.1.2-alpha.x only** (peer floor `^0.1.2-alpha.3`, npm dist-tag `alpha`, install `dsh-better-sidebar@latest`). This version number was never published separately; its content is folded into the **v0.18.0** stable release.
-
-- 🔗 **Adapted to DSH 0.1.2-alpha.3 (published to npm, `alpha` dist-tag)**: the CI mount gate's pin, the `dsh.plugin.json` engines floor, and the `@deepseek-ai/*` peer / devDependencies baseline moved up to 0.1.2-alpha.3 (verified by a real-host mount smoke 14/14). All 117 commits between alpha.2 and alpha.3 were audited point by point: every host contract this plugin relies on (token auth, slash RPC, `MarkdownText` labels, the event-stream and persistence APIs behind `sidechat.events`, `SettingsNamespaceInput`, `SUBAGENT_DESCRIPTOR_VERSION` (still 3), `dsh-client-store`, the profile loader, the node-pty pin) is unchanged, so no code adaptation was needed; alpha.3's breaking changes (the required `BeginSubmissionInput.mode`, the renamed `attachment-invalid` subagent error, the removed SQLite persistence backend, the identity-gated projection change feed) were all verified not to touch this plugin.
-
-### v0.18.0-alpha.0
-
-> 🧪 **Alpha track**: this release targets **DSH 0.1.2-alpha.x only** (peer floor `^0.1.2-alpha.2`, npm dist-tag `alpha`, install `dsh-better-sidebar@latest`); 0.1.0-rc.8 ~ 0.1.1-rc.2 are no longer supported — stable-DSH users should stay on v0.17.1 (npm `latest`).
-
-- 🔗 **Adapted to DSH 0.1.2-alpha.2 (published to npm, `alpha` dist-tag)**: the CI mount gate's pin and the `@deepseek-ai/*` devDependencies baseline moved up to it (verified by a real-host mount smoke 14/14). Adaptation points: `dsh-settings` dropped the runtime `settingsNamespace` export (namespaces are now validated at compile time — the host passes the constant directly); the `dsh-subagent` descriptor version went 2→3 (stamped by the host package; the test assertion follows the `SUBAGENT_DESCRIPTOR_VERSION` constant); the restored `SessionEvent.ignorable` and the Remote gateway's unified `RemoteError` wrapping were verified to not affect this plugin.
-- 🐛 **Fixed blank Side Chat transcripts on DSH 0.1.2-alpha.1+**: transcript polling still called the `ctx.connection.api` face removed in alpha.1 (the error was silently swallowed, so the tab rendered an empty transcript forever). Transcripts now come from the plugin's own `sidechat.events` route (live threads read the in-memory event log, cold threads read session persistence, with `afterSeq` delta pulls, [sidechat-routes.ts](./src/sidechat-routes.ts)).
-- 🧹 **Dropped the pre-alpha (0.1.1-rc.x and older) compatibility layer**: the e2e host RPC collapsed from the dot/slash dual dialect to slash-only (token URL required, [host-protocol.ts](./tests/e2e/host-protocol.ts)); `MarkdownText` labels collapsed to the nested single shape ([markdown-labels.tsx](./src/client/markdown-labels.tsx), no more dual prop names); peerDependencies / devDependencies / `dsh.client.inject` / the chunk externals allowlist all dropped the defunct `@deepseek-ai/dsh-client-runtime` (four synchronized spots).
-
-### v0.17.1
-
-- 🔗 **DSH 0.1.2-alpha.1 adaptation (dual-version compatible)**: fully adapted to DSH 0.1.2-alpha.1's Remote gateway, one-time-token browser authentication, and the `MarkdownText` labels contract change — the plugin works identically on 0.1.0-rc.8 ~ 0.1.1-rc.2 and 0.1.2-alpha.1 (the latter verified by a real-host mount smoke 14/14 against a source build of the GitHub tag; alpha.1 was never published to npm, and the CI pin moved to the npm-published 0.1.2-alpha.2 in v0.18.0-alpha.0). Highlights: all four `MarkdownText` render sites now go through the dual-shape labels helper ([markdown-labels.tsx](./src/client/markdown-labels.tsx)), fixing the `reading 'code'` crash in markdown/mermaid previews on alpha.1; the e2e mount smoke speaks both wire dialects (token-URL cookie exchange, slash `/api` endpoints with parameter-named args, [tests/e2e/host-protocol.ts](./tests/e2e/host-protocol.ts)); dropped the `@deepseek-ai/dsh-client-runtime` peer removed upstream in 0.1.2-alpha.1

-- 🧊 **Git panel freeze + restart loop** ([#376](https://github.com/omdsh-dev/DSH-better-sidebar/pull/376), fixes [#369](https://github.com/omdsh-dev/DSH-better-sidebar/issues/369)): opening the Source Control panel could freeze the whole page, and the frozen layout restored itself after every reload with no way out — three unbounded layers compounding, now all bounded: **① status truncation** — the `git status --untracked-files=all` response is capped at 2,000 entries (capped results carry `truncated` and the panel shows a notice, mirroring `fs.read`'s truncation semantics; worktree change counts inherit the bound), so a huge untracked set can no longer freeze the browser main thread; **② bounded repository discovery** — a non-repository cwd (e.g. the home directory) no longer probes every visible child directory serially without limit: probe timeout 30s→5s, at most 200 probed directories, concurrent requests share one in-flight scan plus a 60s TTL cache, ending the `git rev-parse` spawn storm under `~`; **③ reset escape hatch** — loading with `?dsh-sidebar-reset` drops the persisted layout (shared width included) and starts from the default, breaking the loop even when the page is already hung; persisting resumes once the param is gone; `statusTruncated` copy synced across all 19 dictionaries

-**✨ New features**
-
-- 🪟 **Free windows** ([#354](https://github.com/omdsh-dev/DSH-better-sidebar/pull/354)): drag any tab (built-in or plugin-registered) out of the tab bar **onto the main conversation area** — a dashed drop hint marks the landing zone and release turns it into a floating window (default 390×780, phone-portrait ratio, clamped to the viewport and centered at the drop point). Windows can be moved by dragging the header, resized from the SE corner (≥320×200), raised to the top by clicking anywhere, sent back with the header context menu ("Back to sidebar" / "Close"), and closed with X through the normal `closeTab` lifecycle (pty release etc.). Dragging over a sidebar pane highlights it and releasing **docks** the window back into that pane. `floats` persist per session (restored as-is after refresh, lenient sanitize + geometry clamping). Service semantics: `features` gains `'floatWindows'` — `openTab`'s dedupe/id focus on a floating tab **raises its window** (no duplicate open, no panel expansion), `closeTab` / `activateTab` work on floating tabs and still fire their lifecycle callbacks, `visible` is always true inside a float, and agent-terminal reconcile covers floating windows. Tab content reuses the regular render path; plugin tabs are fully supported. Also ships the 8px-grid spacing cleanup of file sub-pages ([design](docs/plans/2026-08-23-free-window-design.md))
-- 📂 **Model-driven sidebar opens (`sidebar_open` tool)** ([#353](https://github.com/omdsh-dev/DSH-better-sidebar/pull/353)): a new global setting `agentOpenTools` (**off by default**) injects **one** tool letting the model open local **files** (editor tab, deduped by path), **folders** (full-window tree rooted there, `meta.dir`) and **HTTP(S) pages** (browser tab, URL prefilled) in the caller's sidebar. Turning the setting off unregisters the tool and clears the undelivered queue; already-open tabs stay. Opens targeting non-active sessions queue and replay when visible (`/sidebar/ws/agent-opens` push, same trust fence). No new public API and no new `/sidebar/api` routes ([design](docs/plans/2026-08-23-agent-open-tools-design.md))
-- 📝 **README-level inline HTML + table of contents (TOC) in Markdown previews** ([#360](https://github.com/omdsh-dev/DSH-better-sidebar/pull/360)): previews now genuinely render **block-level inline HTML** — badge walls `<div align=center>`, `<details>` blocks nesting markdown, `<br/>`/`<sub>`/`<img>` inside table cells, `<video>`/`<picture>` — all sanitized through a DOMPurify allowlist (`<script>` and other active content stripped, `<a>` forced `_blank rel=noopener`), with local media `src` rewritten to the session media route. With ≥3 headings a floating **TOC** button appears: smooth scroll, auto-expanding folded `<details>` ancestors, collecting headings from HTML segments too. The renderer is still the host `MarkdownText` (shiki / KaTeX / GFM preserved); pure-markdown documents take the original path with zero regression ([design](docs/plans/2026-08-24-markdown-html-toc-design.md))
-- 🌏 **Third-language coverage (19 languages)** ([#339](https://github.com/omdsh-dev/DSH-better-sidebar/pull/339)): optional peer `@huanlin/dsh-plugin-better-locale` adds full dictionaries for ja / de / fr / pt / ko / ar / hi / id / tr / vi / th / ru / it / nl / sv / pl / zh-HK / zh-TW / zh-MO (~340 keys each). Coverage **borrows the DSH English slot**: it is active only while DSH's active locale is `en` and is completely inert under `zh` (no mixed-language UI). The 19 dictionaries are also registered into better-locale so external `ctx.locale.lookup('betterSidebar', key)` callers get the override text. Without better-locale installed `ctx.get('betterLocale')` is undefined and the whole block is a no-op — zh/en behavior is unchanged
-- 🌿 **Multi-repository Git selection + linked-worktree discovery** ([#326](https://github.com/omdsh-dev/DSH-better-sidebar/pull/326) [#285](https://github.com/omdsh-dev/DSH-better-sidebar/pull/285)): when the session cwd is a workspace container rather than a Git repository, the Git panel discovers direct child repositories and shows a **repository selector** — status / branch / history / diff / stage / commit / revert / cherry-pick / file opening are all threaded through the selected repository. Linked-worktree change discovery and per-worktree git operations are transactionally bound to the selected checkout (including delayed pagination responses), stale/prunable worktree targets are rejected, and individual inventory failures degrade safely
-- 🖥️ **Browser loopback allowlist** ([#365](https://github.com/omdsh-dev/DSH-better-sidebar/pull/365)): a new side-card setting `browserAllowedLoopback` (comma-separated host or host:port entries; bare hosts match every port, host:port matches exactly) lets the sidebar browser navigate to explicitly trusted local addresses. Allowlisted loopback pages additionally get the `allow-same-origin` iframe sandbox token — local dev servers (Vite etc.) need a real origin for their module/HMR/fetch pipeline and would otherwise render blank. The page stays cross-origin to the GUI and to every other site; the server-side `browser.probe` route mirrors the same allowlist
-- 📝 **Vue + 28 legacy languages in the editor** ([#202](https://github.com/omdsh-dev/DSH-better-sidebar/pull/202)): `.vue` maps to `@codemirror/lang-vue` (template / script / style dispatch on the `lang` attribute, `<style lang="scss">` preprocessors); zero new dependencies bring scss/sass/less/stylus/ruby/lua/perl/r/dart/scala/groovy/powershell/diff/protobuf/cmake/pug/tcl/haskell/clojure/erlang/julia/pascal/vb/vhdl/stex/objectivecpp via legacy-modes. A throwing language factory degrades to plain text (console.warn) instead of breaking the editor; ambiguous `.v` / `.m` extensions stay unmapped on purpose
-- 🔄 **Editor preview refresh trio** ([#215](https://github.com/omdsh-dev/DSH-better-sidebar/pull/215) [#228](https://github.com/omdsh-dev/DSH-better-sidebar/pull/228), fixes [#167](https://github.com/omdsh-dev/DSH-better-sidebar/issues/167)): a **manual refresh** button for text previews; switching back to preview after an edit-save auto-reloads (suppressed while dirty so drafts survive); a successful save while in preview mode reloads on the saved edge. Automatic polling and the `fs.stat` version endpoint are gone (zero background API traffic)
-- 🖼️ **Local / relative images in Markdown** ([#292](https://github.com/omdsh-dev/DSH-better-sidebar/pull/292)): `![alt](./img.png)`, `/cwd/img.png` and reference-style `[id]: url` destinations are rewritten to `/sidebar/file` media URLs (still bounded by the session cwd) — previews no longer show just the alt text
-- ➕ **New recommended-catalog entry: ego-browser** ([#340](https://github.com/omdsh-dev/DSH-better-sidebar/pull/340)): `@dsh-external/ego-browser` Agent browser tab (registers a sidebar page automatically when better-sidebar is present, falls back to a floating bubble otherwise); description dictionary completed across 19 languages ([#371](https://github.com/omdsh-dev/DSH-better-sidebar/pull/371))
-
-**🐛 Fixes**
-
-- 🛒 **DSH marketplace managed-install compatibility** ([#338](https://github.com/omdsh-dev/DSH-better-sidebar/pull/338)): the public `cordis` entry was removed from `peerDependencies` (the market preview hard-rejects `cordis` in any dependency field — optional does not help), so the npm package satisfies the [dsh-community-market install rules](https://github.com/anywhere-labs/deepseek-harness-desktop/blob/master/dsh-community-market/docs/install-and-uninstall.zh.md) — catalog sources (dshfind / 1024Store) can re-issue the `repository_backlink` verified target and the plugin becomes installable through the Desktop market
-- 🔤 **Type base migrated to `@deepseek-ai/cordis`** ([#338](https://github.com/omdsh-dev/DSH-better-sidebar/pull/338)): the declaration surface (`src/context-types.ts`) no longer depends on or restates the public `cordis` — `Context` is now an **intersection** of the real vendored cordis Context with the structural service faces, and the `ctx.betterSidebar` type merge lives on `@deepseek-ai/cordis`. **Consumer migration**: change `import type { Context } from 'cordis'` to `import type { Context } from '@deepseek-ai/cordis'` (the `import type {} from 'dsh-better-sidebar'` merge path is unchanged); plugins that never used that import are unaffected
-- 🧩 **All internal `ctx.betterSidebar` reads fixed** ([#357](https://github.com/omdsh-dev/DSH-better-sidebar/pull/357), fixes [#356](https://github.com/omdsh-dev/DSH-better-sidebar/issues/356)): on npm-installed DSH 0.1.1-rc.x (web bundle) the sidebar died on every page load (`cannot get property "betterSidebar" without inject`) — the 26 internal direct reads now go through `ctx.get('betterSidebar')` (root reflect-store resolution, immune to the fiber chain); external consumers keep `inject: ['betterSidebar'] + ctx.betterSidebar`
-- 🔐 **Session-workspace boundary for file APIs** ([#345](https://github.com/omdsh-dev/DSH-better-sidebar/pull/345), fixes [#328](https://github.com/omdsh-dev/DSH-better-sidebar/issues/328)): fixed `fs.tree / fs.read / fs.write` workspace escapes; media, HTML preview and uploads share real-path symlink validation; regression tests for absolute paths, symlinks, uploads and nested Git sessions
-- 🪟 **Panel-host layering and viewport clipping** ([#330](https://github.com/omdsh-dev/DSH-better-sidebar/pull/330) [#278](https://github.com/omdsh-dev/DSH-better-sidebar/pull/278), fixes [#277](https://github.com/omdsh-dev/DSH-better-sidebar/issues/277)): panel host z-index 40→25 — below the DSH cordis dynamic-plugin layer (30), so the workbench no longer covers cordis inventory/approval surfaces (still above AppFrame's 20 and below the 100+ float stack); `overflow: hidden` on the host clips at the viewport edge, so collapsed panels no longer stretch the document into bidirectional scrolling (measured `scrollWidth` 2289→1672 / `scrollHeight` 1280→1032, any skin)
-- 📐 **Layout-push hardening** ([#310](https://github.com/omdsh-dev/DSH-better-sidebar/pull/310) [#130](https://github.com/omdsh-dev/DSH-better-sidebar/pull/130) [#180](https://github.com/omdsh-dev/DSH-better-sidebar/pull/180)): conversation column gets `min-height: 0` + `overflow: hidden` + `overflow-wrap: anywhere` (long unbreakable URLs / OAuth links no longer push the composer and left-rail Settings out of the viewport); the layout-push effect is split into "set only" + "remove only on unmount" and the width push is gated on `panelOpen` — dragging the bottom height with the right panel closed no longer squeezes the conversation, and release no longer flashes full-width; `useLayoutEffect` removes cross-paint full-width frames; all three drags flush the final frame and sync `centerRect.right` before committing; bottom height caps at `viewportHeight - PANEL_MIN`; drag handles no longer highlight mid-drag
-- 📱 **Mobile: unavailable-sidebar clarity + 1px overflow** ([#254](https://github.com/omdsh-dev/DSH-better-sidebar/pull/254)): with no session the toggle uses `aria-disabled` — keeping the non-executable semantics while allowing touch/keyboard focus so the "select a session to use the sidebar" tooltip is reachable; the panel uses `border-box` so mobile `100vw` includes the left border and no longer causes 1px horizontal overflow
-- 📏 **Side-card width shared across sessions** ([#36](https://github.com/omdsh-dev/DSH-better-sidebar/pull/36)): panel width is a layout preference, not session content — "last drag wins" writes the global `dsh-sidebar:v1:width` key that fresh and cached session switches adopt; without a global key (first run / pre-existing sessions) behavior is byte-for-byte unchanged
-- 🧹 **Terminals close immediately on session delete** ([#130](https://github.com/omdsh-dev/DSH-better-sidebar/pull/130)): new `PtyManager.closeSession()` subscribing to DSH's `session/disposed` — deleted sessions no longer wait for the 30s reconnect grace to release their terminals (agent terminals are agent-lifecycle-owned and untouched)
-- 🔍 **Filename search skips noise directories** ([#342](https://github.com/omdsh-dev/DSH-better-sidebar/pull/342)): `node_modules` / `.pnpm-store` / `.yarn` / `.turbo` / `.next` / `dist` / `build` / `coverage` etc. (case-insensitive, `.git` still skipped) — huge dependency trees no longer burn the 100k visit budget and return `truncated` early, so real files in later directories (`docs/`) are found; no `.gitignore` semantics, still filename lookup
-- 📝 **Mermaid global error rendering suppressed** ([#341](https://github.com/omdsh-dev/DSH-better-sidebar/pull/341)): `suppressErrorRendering` enabled — invalid diagrams no longer inject a large error SVG into `document.body`; the component-level error fallback and source display remain
-- 🖥️ **Terminal Nerd Font icon fallback** ([#190](https://github.com/omdsh-dev/DSH-better-sidebar/pull/190)): supplementary-plane PUA icons in starship / powerlevel10k prompts (Nerd Fonts v3 Material icon set) no longer render as tofu — `withIconFontFallbacks()` appends Nerd Font icon families to the winning base font (before the first generic family, deduped by family name, CSS global keywords filtered, no color-emoji fonts)
-- 🌐 **HTML preview declares UTF-8** ([#193](https://github.com/omdsh-dev/DSH-better-sidebar/pull/193), fixes [#170](https://github.com/omdsh-dev/DSH-better-sidebar/issues/170)): `/sidebar/html` responses carry `charset=utf-8` (Chinese fragments without `<meta charset>` no longer mojibake); original file bytes preserved
-- 🧪 **trust-fence Origin compared by hostname** ([#182](https://github.com/omdsh-dev/DSH-better-sidebar/pull/182)): some Chromium builds (Edge 151) serialize the Origin of non-default-port loopback pages without the port — `http://127.0.0.1` against `Host: 127.0.0.1:3080` no longer 403s (mirrors DSH's official gateway fence); different hostnames and opaque null origins are still rejected
-- 🪟 **"Show in folder" now reveals in the explorer** ([#94](https://github.com/omdsh-dev/DSH-better-sidebar/pull/94)): the folder-reveal gesture no longer opens the directory as a file in the editor (`"..." is a directory`) — `revealInExplorer` switches to the explorer tab, auto-expands a collapsed panel, expands the parent folder and highlights/scrolls to the produced file; the produced-files selector now reads the engine's Turn deliverables (same source as ui-deliverables)
-- 🖱️ **Panel-drag layout flash fixed** ([#180](https://github.com/omdsh-dev/DSH-better-sidebar/pull/180)): dragging the bottom height with the right panel closed no longer shifts the conversation left; release no longer flashes full-width before snapping back
-- 🖥️ **PowerShell installer fixes** ([#47](https://github.com/omdsh-dev/DSH-better-sidebar/pull/47)): the remote entry is now "download the script → strip the UTF-8 BOM → run it in memory", so `-Version` / `-DryRun` work again under Windows PowerShell 5.1 (the BOM no longer eats the leading `param(...)`); `pnpm --version` is checked before touching the profile (major <10 fails with a clear error and exit code 1)
-- 🔄 **Browser embed probing GET fallback** ([#69](https://github.com/omdsh-dev/DSH-better-sidebar/pull/69)): when a HEAD response omits both `Content-Security-Policy` and `X-Frame-Options`, probe retries once with GET — sites like Alibaba Bailian that only advertise their embed policy on GET no longer show a misleading "refused to connect"; they get the friendly "site refuses embedding" panel with an "open in browser" button
-- 🔧 **git-source installs fixed via `unrun` devDependency** ([#336](https://github.com/omdsh-dev/DSH-better-sidebar/pull/336)): tsdown 0.22 loads its config through `unrun` and pnpm 11 does not auto-install peer deps — git-hosted `prepare` no longer fails with `Failed to import module "unrun"` (npm tarballs unaffected)
-- 🍃 **Strict `ctx.effect` also fixed 4 latent sites**: interception / IME-guard effect bodies returned `undefined` on failure instead of a disposer (invalid shape under the vendored cordis effect contract) — now a no-op disposer

-All changes since v0.15.1:
-
-**✨ New features**
-
-- 🗂️ **"Open in app" submenu in the file tree** ([#334](https://github.com/omdsh-dev/DSH-better-sidebar/pull/334)): the file-tree context menu gains an "Open in app >" submenu — built-in openers (reveal/select in file manager, VS Code, Cursor, Zed), each with a pin button that promotes it to a top-level context-menu item (click again to unpin); with an optional SSH host configured, VSCode-family entries switch to the `vscode-remote/ssh-remote+<host>/<path>` protocol and local-only entries hide automatically; custom editors supported (name + URL template with `{path}` + "VSCode-family" flag, configured in the Files card gear popup). Open actions go through the new host route `POST /sidebar/api/open.external` (argv-array spawn, no shell injection) ([design](docs/plans/2026-08-22-open-with-menu-design.md))
-- 📑 **Tab context menu** ([#331](https://github.com/omdsh-dev/DSH-better-sidebar/pull/331)): right-clicking a tab offers **Close / Close others / Close to the left / Close to the right**, scoped to the current pane (tab group); items grey out when there is nothing to close; the menu only opens — it never switches the active tab; bulk closes go through the existing per-tab `onClose` path so lifecycle callbacks, pty release and agent-terminal shutdown all stay intact
-- 📄 **Diff files collapsed by default** ([#270](https://github.com/omdsh-dev/DSH-better-sidebar/pull/270)): each changed-file header is now an accessible expand/collapse control; recognized source files expand by default while tests, docs, generated files, lockfiles and unknown types stay collapsed; the existing 500-row cap for expanded content is preserved
-- 📖 **README update**: feature tour converted to a table (two screenshots per row, saves space); community section now shows the WeChat group and QQ group QR codes ([#325](https://github.com/omdsh-dev/DSH-better-sidebar/pull/325), QQ group 577011007)
-
-**🐛 Fixes**
-
-- 🪟 **Prune empty restored panes** ([#268](https://github.com/omdsh-dev/DSH-better-sidebar/pull/268)): persisted split panes left empty when ephemeral diff tabs were dropped no longer survive as full-size blanks — `sanitizeState` now also prunes the empty split leaf and repairs the stale active-pane pointer; a fully empty workbench keeps its single empty pane
-- 🖥️ **Hide spawned git windows on Windows** ([#301](https://github.com/omdsh-dev/DSH-better-sidebar/pull/301), fixes [#124](https://github.com/omdsh-dev/DSH-better-sidebar/issues/124)): the shared `runGit()` spawn options now set `windowsHide: true`, so repo-status polling and git actions no longer flash console windows on Windows (no behavior change on other platforms)
-- 📁 **Untracked files inside new folders** ([#242](https://github.com/omdsh-dev/DSH-better-sidebar/pull/242)): `git status` switched from `--untracked-files=normal` to `--untracked-files=all` — each file inside a new folder now shows as its own row and its diff can be loaded (no more `fs.read` "is a directory" error), matching VSCode's default behavior
-- ⚡ **Per-frame React re-renders eliminated for toggles/drags** (closes [#315](https://github.com/omdsh-dev/DSH-better-sidebar/issues/315)): `centerRect` moved to a ref with direct DOM writes to the bottom bar (zero React renders); `TabContent` memoized with an explicit comparator; a new frame-batcher coalesces Divider/dock drags per frame; meaningless locate passes skipped during drags. 4x CPU-throttled A/B: >17ms frames on toggle collapse 19→6 / expand 24→4~6, p95 21ms→15ms; drags unchanged (non-regression)

-- 💬 **Codex-style transcript rework for Side Chat** ([#314](https://github.com/omdsh-dev/DSH-better-sidebar/pull/314)): transcript rows became **collapsible** — tool calls, thinking and context injections share one quiet single-line chrome (chevron + label + one-line argument summary) that expands into an indented body on a hairline thread, no cards or fills; streaming labels and a creating hero shimmer (shimmer = generating), failed tools go danger, `prefers-reduced-motion` stills every loop; **the first question is no longer swallowed by the boundary prompt** — context injection and first contact are delivered as separate events (boundary + parked snapshot ride `agent.inject`, the question wakes the driver), so the transcript maps injections onto a collapsible injection row while genuine user messages — the first one included — render as user bubbles; legacy threads' first message is split out into its own bubble too
-- 📖 **README rewrite**: feature tour (real UI screenshots per feature), user-facing DSH compatibility badges, simplified install (`add` → `approve-builds` → `add`, node-pty-safe build, paste-to-DSH install prompt), 28+ plugin ecosystem with per-category collapsed listings

-- 🖥️ **Terminal pty stays alive across conversation switches** ([#323](https://github.com/omdsh-dev/DSH-better-sidebar/pull/323)): switching sessions is no longer treated as a transient drop — the client sends a `park` control frame on unmount and the host skips the 30s reconnect-grace countdown; switching back (`open()` cancels parked) or explicitly closing the tab resumes the normal lifecycle; agent terminals keep their indefinite lifetime
-- 📂 **File-tree upload overlay no longer intercepts Tab drags** ([#317](https://github.com/omdsh-dev/DSH-better-sidebar/pull/317)): dragging tabs (reorder / cross-pane split) across the explorer no longer shows the upload overlay or swallows the event — gated on `dataTransfer.types` containing `Files` (consistent with the panel-host shield), so tabs land normally; OS file drags behave as before
-- 💬 **Subagent auto-open debounced** ([#314](https://github.com/omdsh-dev/DSH-better-sidebar/pull/314)): Side Chat thread creation no longer pops the task page — the 0→N trigger rearms for 500ms and re-evaluates the original baseline against the live snapshot, by which time the title filter recognizes the thread; genuine subagents still auto-activate the Tasks page (wide viewports expand the sidebar, while narrow viewports prepare the tab without forcing the drawer open)

-All changes since v0.14.0:
-
-**✨ New features**
-
-- 💬 **Side Chat (beta) tab** ([#286](https://github.com/omdsh-dev/DSH-better-sidebar/pull/286)): Codex-style side threads, **one independent tab per conversation** — the child inherits the parent's full context (completed turns + pending messages + the in-progress turn's assistant output and tool activity, honestly frozen with an "interrupted" marker); created with an identical composition (same preset / provider / model) so the first request reuses the parent's input prefix cache; threads stay invisible in the main session list with zero subagent-catalog noise; follow-ups survive DSH restarts (auto cold-resume); one-click "Save as new session" promotes the thread to a top-level session ([design](docs/plans/2026-08-20-sidechat-tab-design.md))
-- 📤 **Upload into the files window** ([#239](https://github.com/omdsh-dev/DSH-better-sidebar/pull/239)): header "upload file / upload folder" buttons plus drag-drop (drop on the tree body = workspace root, on a directory row = that directory, on a file row = its parent directory, VSCode semantics); full-window blurred progress overlay while uploading (per-file progress + cancel / Esc); buttons disabled while busy, tree refreshes after the upload settles
-- 🧩 **Desktop compatibility in four options** ([#284](https://github.com/omdsh-dev/DSH-better-sidebar/pull/284)): "Position compatibility mode" is now a main-row dropdown — **Auto-detect** (default, conservative: only the standard Window Controls Overlay geometry contributes; real 32/36px caption-overlay heights per shell, live on maximize/restore; zero modification on plain web) / **DSH official web** (explicitly no adaptation) / **Shell preset** (built-in, opt-in; only shells that appeared in this repo's issues/PRs with 100+ stars, "detected" badge when the environment matches) / **Custom** (free-form CSS + shift distance). Documents that already carried compatibility values migrate to the custom scheme; interactive chrome opts out of desktop drag regions (`no-drag`); the bottom-push anchor is a composite selector (`[data-pane]` and `:has(> [data-slot])`)
-- 🎛️ **Settings page UI/UX modernization** ([#300](https://github.com/omdsh-dev/DSH-better-sidebar/pull/300)): the side-card secondary-settings entry is now a full-width "Feature settings" strip at the card bottom (replacing the invisible corner gear — much easier to discover); coordinated two-tone enabled state (brand activation accent + success-green check badge); every color is still `--dsw-alias-*` token-derived so skins follow automatically
-- ➕ **New entries in the recommended-plugin catalog**: `dsh-docs-panel` (global docs, [#230](https://github.com/omdsh-dev/DSH-better-sidebar/pull/230)), `dsh-flowglass` ([#261](https://github.com/omdsh-dev/DSH-better-sidebar/pull/261)), `dsh-git-forge` and `dsh-ssh-tunnel` ([#204](https://github.com/omdsh-dev/DSH-better-sidebar/pull/204)), `dsh-turn-review` ([#102](https://github.com/omdsh-dev/DSH-better-sidebar/pull/102))
-
-**🐛 Fixes**
-
-- ⚡ **Batched live preview for the subagent page** ([#298](https://github.com/omdsh-dev/DSH-better-sidebar/pull/298)): the old implementation polled `subagents.history` per running subagent, each poll triggering a full host-side enumeration — an O(N²) amplification that stalled the page with many concurrent subagents; now a single batch route `subagents.live` (one enumeration of the whole tree) plus one client poller with a single in-flight request; display logic and copy unchanged
-- 🖱️ **Interrupted / fast-release drags no longer roll back** ([#249](https://github.com/omdsh-dev/DSH-better-sidebar/pull/249), closes [#247](https://github.com/omdsh-dev/DSH-better-sidebar/issues/247) [#248](https://github.com/omdsh-dev/DSH-better-sidebar/issues/248)): interrupted or fast-released drags commit the last known position; HMR re-activation re-locates the center column (fixes the blank bottom panel after a hot reload)
-- 📐 **Push variables stay effective while mounted** ([#259](https://github.com/omdsh-dev/DSH-better-sidebar/pull/259), fixes [#258](https://github.com/omdsh-dev/DSH-better-sidebar/issues/258)): the bottom panel no longer flashes full-width after a drag is released
-- 🔐 **Workspace boundary hardening for file APIs** ([#328](https://github.com/omdsh-dev/DSH-better-sidebar/issues/328)): `fs.tree/read/write`, media, HTML preview, and uploads now share real-path containment checks that reject outside absolute paths and symlink escapes
-- 🔧 **Adapted to DSH 0.1.1-rc.1 / rc.2 (@next)** ([#297](https://github.com/omdsh-dev/DSH-better-sidebar/pull/297) [#305](https://github.com/omdsh-dev/DSH-better-sidebar/pull/305)): no code changes needed
-- 🔒 **Upload-chain hardening** ([#239](https://github.com/omdsh-dev/DSH-better-sidebar/pull/239)): empty and absolute `relativePath` segments are refused outright; uniquely named temp files (concurrent uploads stay independent, crashed processes never block later uploads); write-stream error listeners (a failing disk can no longer crash the host); client error codes unified with the wire (`too-large`), 413s localized
-
-### v0.14.0
-
-> ⚠️ This release requires DSH ≥ 0.1.0-rc.8. All changes since v0.13.1:
-
-**✨ New features**
-
-- 🖼️ **Unified panel-host injection refactor** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): panels/toggle clusters moved into a `[data-dsh-panel-host]` fixed containing block (`fixed inset-0 z-40`), immune to desktop-shell intermediate transforms hijacking `fixed`; mount self-check (page-level transform → `data-dsh-panel-host-degraded` degraded sync, judged on uncorrected geometry, exits only when the ancestor transform is gone); push anchor switched to `#root [data-dsh-frame] > [data-pane="conversation"]` + `#root` calc width against desktop-shell additive overflow; chunk revalidation on activation (HEAD+ETag keeps unchanged chunks, 5s timeout fails open); `visualViewport` keyboard inset + `env(safe-area-inset-*)` mobile adaptation
-- 📂 **Separate file windows by default** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): `editorExplorer` now defaults to **separate** — tree clicks / file opens create a new tab per path and the path-less window is a pure file manager; merged mode stays available as an opt-in
-- 🖥️ **Terminal shell / shellArgs configurable from the settings page** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): the terminal card's gear popup gains "Shell path" and "Shell arguments" rows (previously yaml-only via `cordis.patch.yml`) — saved values take effect immediately for terminals opened afterwards (UI terminals and model `terminal_create` alike); empty keeps the existing yaml → `$SHELL` / login shell / `powershell.exe` resolution order
-- 🏷️ **Version badge on the settings page** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): the side-card settings section now opens with a `DSH-better-sidebar v0.14.0` identity badge (version synced with the service instance, test-guarded)
-- 🔍 **Add-plugin catalog: search / grouping / independent scroll** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): built for a growing plugin ecosystem — a live search box (filters by name / id / description), optional `category` grouping for entries, and an independently scrolling list (the modal no longer grows unbounded with catalog size)
-
-**🐛 Fixes**
-
-- 🧩 **rc.8 module-system migration** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): rc.8 no longer exposes the `window.__DSH_MODULES__` page global (it moved to the `ctx.modules` service), which broke every lazy chunk's externals resolution — the client now injects the `modules` service and shares it with chunk-bundle copies through a plugin-owned global (terminal / editor / Mermaid on-demand loading restored)
-- 🧩 **Chunk revalidation barrier hardening** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): HEAD revalidation gains a 5s timeout (fails open on a stuck route so the barrier can never wedge lazy loads); `resetChunks` clears a pending revalidation barrier
-- 🖱️ **Drag robustness** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): fast releases (browsers merge/lose pointermove bursts) commit the last known dragged position instead of rolling back; `pointercancel` / lost-capture interruptions keep the drag result too; the center column is re-measured right after commit (no mid-frame bottom-panel width jump); HMR re-activation re-locates the center column via an `<html>` style observer plus a retry when the bottom panel opens (fixes the blank bottom panel / shifted input bar after a hot reload)
-
-### v0.13.1
-
-**✨ New features**
-
-- 📊 **Safe Mermaid rendering in the Markdown preview** ([#164](https://github.com/omdsh-dev/DSH-better-sidebar/pull/164)): when a previewed md file contains mermaid fences, a `client-mermaid.js` chunk (~7MB) is served on demand (zero load without mermaid); defense-in-depth rendering — `securityLevel: 'strict'` + `htmlLabels: false` (node labels use real SVG `<text>`) + a second sanitize pass before SVG injection (foreignObject/script/foreign HTML elements removed, `@*`/`on*`/`href` attributes stripped); click a diagram to zoom in a modal overlay (wheel zoom centered on the cursor, drag pan, toolbar & shortcuts), re-renders with light/dark theme, falls back to the raw code block on parse failure
-- 🖥️ **Configurable terminal shell & shellArgs** ([#125](https://github.com/omdsh-dev/DSH-better-sidebar/pull/125)): `cordis.patch.yml` `better-sidebar.config` can set `shell` / `shellArgs` (a non-empty `shellArgs` fully replaces the defaults; unset keeps the previous auto-resolution of `$SHELL` / login shell / `powershell.exe`), applied to both UI terminals and agent terminals (`terminal_create`); terminal tab titles now show the shell name (bash/zsh/powershell) and internal tab ids use UUIDs so the same shell can open multiple terminals
-
-**🐛 Fixes**
-
-- 🔗 **Aggregate double-mount auto-yield** ([#200](https://github.com/omdsh-dev/DSH-better-sidebar/pull/200)): when an aggregate package (e.g. dsh-web-ui-all) mounts the same package under its own entry id, the guard expression in `cordis.patch.yml` disables the plugin's own `better-sidebar` row so `/sidebar/api` is no longer registered twice (`duplicate prefix route` crashing the whole plugin tree / `dsh web`); standalone installs behave as before
-- 🔧 **Adapted to DSH 0.1.0-rc.7** ([#207](https://github.com/omdsh-dev/DSH-better-sidebar/pull/207), fixes [#206](https://github.com/omdsh-dev/DSH-better-sidebar/issues/206)): fixes the `agent-presets: refusing to compose an unscoped context` error when picking a model / sending a message after DSH moved to rc.7
-
-### v0.13.0
-
-**✨ New features**
-
-- 📁 **Files window merged with the explorer** ([#151](https://github.com/omdsh-dev/DSH-better-sidebar/pull/151)): new `editorExplorer` setting (editor card gear) — file tabs gain a path-input header plus a toggleable right-docked file tree (per-tab open/width memory, drag-resize 160–480px from the left edge, global filename search via the host `fs.search` route with a hard budget, skipping `.git` and symlink dirs); in separate mode (default) tree clicks / Enter in the path input open each file **in its own new tab**, merged mode switches the current tab **in place**; fresh sessions seed an empty Files window instead of the explorer tab, and a path-less window is a bare file manager in separate mode / a chrome'd empty file window in merged mode; the tree context menu offers "Open in new tab" and "Open to the side" (split)
-- 🎛️ **Select rows for declarative settings** ([#151](https://github.com/omdsh-dev/DSH-better-sidebar/pull/151)): settings rows gain `type: 'select'` (`options` with value/title/desc/icon, `multi` stores the picked values as an array); options with icons render big-icon option cards and keep the icon in the closed anchor; `editorExplorer` became an iconed select (merged vs separate); the capability list gained `settingSelect`
-- 🔀 **Mutual exclusion with the dsh-web-ui family right panel** ([#181](https://github.com/omdsh-dev/DSH-better-sidebar/pull/181)): reads the `aionui-panel` settings namespace's provider choice — when "Use aionui-panel" is selected, the whole better-sidebar (right sidebar / bottom panel / floating entry / all takeovers) does not mount; with DSH-better-sidebar (or no aionui installed) it behaves as before. Takes effect live after a settings save (settings-document push), no reload needed
-
-### v0.12.3
-
-**✨ New features**
-
-- 🎨 **Skin compatibility (token-driven)**: fully consumes DSH design tokens and follows the dsh-web-ui skin center's 10 skins automatically; terminal/editor surfaces fall back to opaque backgrounds under transparent/translucent-glass token values so text never scrolls over the skin art ([#110](https://github.com/omdsh-dev/DSH-better-sidebar/pull/110), fixes #106 #105 #90 #60, also #52 #57 #92)
-- 🗂️ **Unified path handling**: UNC / symlink classification (directory symlinks expandable, broken links highlighted) + HTML-route platform guards ([#134](https://github.com/omdsh-dev/DSH-better-sidebar/pull/134), #65 #67 #43 #79 #115)
-- 🖥️ **Configurable terminal shell**: custom shell setting with Windows pwsh auto-probe ([#95](https://github.com/omdsh-dev/DSH-better-sidebar/pull/95))
-- 📝 **Editor languages**: C# / Kotlin / Swift syntax highlighting ([#120](https://github.com/omdsh-dev/DSH-better-sidebar/pull/120))
-- 🧭 **Settings nav icon**: settings-page navigation icon and layout polish ([#114](https://github.com/omdsh-dev/DSH-better-sidebar/pull/114))
-- ➕ **Recommended-plugin catalog**: added `dsh-git-remotes` — Git Remotes tab (branches/upstream/ahead-behind, fetch with prune, ff-only pull, confirm-before-push; does not replace the built-in stage/commit tab) ([#91](https://github.com/omdsh-dev/DSH-better-sidebar/pull/91)); and `dsh-video-preview` — inline video preview (.mp4/.webm/.mov/.mkv/.avi etc.) backed by a /video host route with HTTP Range (206) scrubbing, not capped by the 20MB mediaLimit ([#126](https://github.com/omdsh-dev/DSH-better-sidebar/pull/126))
-
-**🐛 Fixes**
-
-- 🔧 **xterm migration**: deprecated xterm dependency migrated to `@xterm/xterm` (Closes [#122](https://github.com/omdsh-dev/DSH-better-sidebar/issues/122), [#128](https://github.com/omdsh-dev/DSH-better-sidebar/pull/128))
-- 📝 **Markdown editor**: selection-to-conversation popup restored ([#24](https://github.com/omdsh-dev/DSH-better-sidebar/pull/24))
-- 🖼️ **Markdown preview renders local/relative images**: image destinations that point at local files (relative/absolute paths, reference-style `[id]: url`) are rewritten to `/sidebar/file` media URLs and displayed in the preview (previously only absolute http(s) images rendered; relative paths showed just the alt text)
-- 🐛 **node-pty load failure no longer crashes the server** ([#140](https://github.com/omdsh-dev/DSH-better-sidebar/issues/140)): the host half now lazy-loads node-pty — when it is missing the plugin still mounts, the terminal shows a repair banner (copyable command + Retry button), and agent terminal tools are skipped
-- 🧪 Test engineering: unit spec split (#141) + flaky smoke cleanup fix

-## 🔌 Service API
-
-Since v0.4.0 the plugin exposes the `ctx.betterSidebar` service — other plugins can register sidebar pages and file viewers (the 5 built-in tabs + 3 viewers register through the same service). v0.12.1 completed the base capabilities (complete type exports, capability detection, state subscription, tab badges, lifecycle callbacks, targeted open, plugin-owned settings, etc.).
-
-Full integration docs (complete fields, matching algorithm, HMR pitfalls, declarative settings, version detection, the native-sidebar surface and the skinning contract): **[`docs/external-plugin-guide.md`](./docs/external-plugin-guide.md)**; repository rules (hard constraints / CI / release) live in [`AGENTS.md`](./AGENTS.md).
-
-### ➕ Add Plugins (recommended plugin catalog)
-
-The dashed cards at the end of the "Sidebar content" / "File viewers" grids in the "Side Cards" settings section open the **Add tab plugins** / **Add preview plugins** modals: each declares its open extension point, offers a "**Browse more plugins on GitHub**" button (the [GitHub topic `dsh-better-sidebar`](https://github.com/topics/dsh-better-sidebar)), and lists the recommended catalog (name / repo / description / install script) — "**Open**" jumps to the repo, "**Copy**" writes the install command to the clipboard.
-
-**Curating a new plugin**: append a `PluginEntry` to [`src/client/plugins-tabs.ts`](./src/client/plugins-tabs.ts) (tab registrations) or [`src/client/plugins-viewers.ts`](./src/client/plugins-viewers.ts) (file-previewer registrations) and tag your repo with the `dsh-better-sidebar` topic; data integrity is guarded by `tests/plugin-list.spec.ts`.
-
-## 🛠️ Development & Build
-
-```sh
-pnpm install      # @deepseek-ai/* devDependencies resolve (baseline 0.1.7-rc.1, alpha dist-tag) — no token needed
-pnpm typecheck    # tsc --noEmit
-pnpm lint         # eslint . (flat config: js + typescript-eslint + react-hooks recommended)
-pnpm build        # → lib/index.js + lib/invariant.js + lib/client.js + lib/client-registry.js + lib/types
-pnpm test         # vitest (includes manifest consistency guard; build first)
-pnpm watch        # tsdown --watch
-```
-
-**Make thin wrappers** (`make help` lists every target; package.json stays the single source of truth):
-
-```sh
-make check          # aggregate gate: typecheck → build → test → check:consumer-types (mirrors CI)
-make mount          # real-mount smoke: build + pack → install Chromium → pnpm test:mount
-make clean          # remove lib/, *.tgz, playwright-report/, test-results/
-```
-
-`pnpm check:consumer-types`: the consumer-facing declaration-surface guard — type-checks the built `lib/types` from a browser-only consumer's perspective (no `@types/node`, `skipLibCheck: false`); run `pnpm build` first.
-
-**Architecture**: a single npm package with host/client halves — host (`src/index.ts`): `/sidebar/api/*` JSON API, `/sidebar/file` media route, `/sidebar/html` preview route, `/sidebar/upload` upload route, and two WebSockets (`/sidebar/ws/agent-opens` for model-driven opens, `/sidebar/ws/fs-watch` for the file tree's directory watch; fs / git / preview are all session-scoped behind a trust fence); client (`src/client/index.tsx`): portal sidebar + views + link takeover; state persisted per session in localStorage. Organized per DSH official conventions (no default export, dual client bundles); no dependency on npm / checkout at runtime (`@deepseek-ai/*` provided by the web profile).
-
-## 🔐 Security
-
-- Routes protected by a Host-header trust fence (same as `/api`); `fs.write` is atomic; media/preview routes only serve files inside the session cwd (unless `workspaceFence` is turned off in settings); git only shells out to the CLI and never sets identity
-- HTML preview content renders in an **opaque-origin sandboxed iframe** (no `allow-same-origin`/`allow-top-navigation`, `no-referrer`, all permission policies disabled); the `/sidebar/html` route carries a CSP `sandbox` + size/path bounds
-- The settings page can disable the HTML preview's sandbox per feature (`htmlViewerNoSandbox` / `htmlViewerDefaultUnsafe`, off by default, with a warning) — when off, content shares the origin with the UI; only recommended for fully trusted content. **The web tab's sandbox is no longer this plugin's surface**: the browser view comes from the host (desktop profile); see DSH's own docs for its sandbox and navigation policy
-
-## ⚠️ Known Limitations
-
-- Git has no push/pull/fetch; Markdown previews provide a manual refresh button with confirmation before discarding unsaved edits; the file tree only watches **expanded** directories (collapsed folders are unsubscribed, and there is no recursive whole-workspace scan); tool inline file-open buttons cannot be intercepted
-- **Which read-only previews exist is the host's call**: spreadsheets / PDF / images / Office go to DSH's own `ui-sidebar-documentpreview`, while the plugin renders only Markdown / HTML and the editable text buffer; the host implementation (rendering details, zoom, refresh timing) follows the DSH version
-- **The browser view exists only in the desktop profile**: the Web profile has no host `browser` kind and the plugin no longer ships a browser tab, so web tabs are desktop-only; login state / third-party cookies / `X-Frame-Options` limits follow the host implementation
-- HTML preview renders the saved file (not unsaved drafts)
-- No bottom panel on mobile (<768px): on narrow screens its tabs merge into the right sidebar once (after migrating back to desktop they stay in the right sidebar); the desktop bottom panel is only available on wide viewports. Without a selected session, tapping the subdued toggle shows the select-session message; with a selected session, it opens the full-width drawer
-
-## 🖥️ Platform Support
-
-Windows / Linux / macOS (macOS validated daily; the rest covered by unit tests). The plugin carries no native dependencies (the terminal and `node-pty` went back to DSH wholesale), so building needs only Node + pnpm, with no compiler toolchain.
