+### 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
+- 📏 **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 `irm` 下载 → `.TrimStart([char]0xFEFF)` 去 BOM → `ScriptBlock.Create` 执行（`-Version` / `-DryRun` 参数在 Windows PowerShell 5.1 下恢复生效）；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）

 - ⚡ **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）
-- 🛒 **DSH 市场受管安装兼容**：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），使 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)——目录（dshfind / 1024Store）里的本插件条目将重新获得 `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`**：声明面（`src/context-types.ts`）不再依赖/重述公开版 cordis——`Context` = 真实 vendored cordis Context 与结构化服务面的**交集**，`ctx.betterSidebar` 类型合并改挂在 `@deepseek-ai/cordis` 上。**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）；对未使用该导入的插件无影响
-- 🍃 **`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）

+### v0.16.0
+
+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
+- 📏 **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)): remote entry unified as `irm` download → `.TrimStart([char]0xFEFF)` BOM removal → `ScriptBlock.Create` execution (`-Version` / `-DryRun` work again under Windows PowerShell 5.1); `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

 ### v0.15.2
 
 All changes since v0.15.1:
@@ -275,12 +319,6 @@ All changes since v0.15.1:
 - 🖥️ **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)
-- 🛒 **DSH marketplace managed-install compatibility**: 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 now 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`**: 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
-- 🍃 **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
