+# Web Shell file browser
+
+[English](web-shell-file-browser.md) | [简体中文](web-shell-file-browser.zh-CN.md)
+
+## Problem and current state
+
+The right extension area offers file changes but cannot browse workspace files.
+The requested interface adds a Files entry beside the existing actions, with the
+selected file on the left and a persistent directory tree on the right.
+
+## Proposed solution
+
+Add an opt-in `files` right-panel item and a workspace-owned `files` tab. Enable
+it in the standalone page. The empty-state action and add menu open or activate
+one Files tab per workspace. Reuse existing panel sizing, closing, fullscreen,
+and persistence behavior. Before selecting a file, show only the full-width tree.
+Selecting a file opens the two columns with about 70% for content and 30% for
+the tree, without rebuilding the tree; subsequent
+file selections keep it visible.
+
+Use `@pierre/trees` for the read-only tree and `@pierre/diffs` File for read-only
+source rendering. Retain existing Markdown, HTML and image previews. Markdown
+and HTML default to rendered preview with a source toggle. Other files use the
+existing supported-file/error behavior. No Git state or editing is enabled.
+
+Load only the root and expanded directories through the existing daemon API.
+Keep loaded paths in the Pierre model; directory expansion loads direct children.
+Search covers loaded paths only and never fetches search-expanded directories.
+Keep the raw filter input unchanged; show an explicit no-match state within loaded
+paths. Selection or Escape closes filtering. A nonempty filter consumes Escape
+before fullscreen or drawer dismissal; IME composition keeps its native Escape.
+Refresh clears directory cache and reloads
+the root and selected file, collapsing branches. Hide the filter-scope explanation
+and per-directory loading log; show retryable errors, empty directories and
+truncated-list warnings only when needed. Never recurse into symlinks.
+Files expose a right-click menu for relative/absolute path copying, downloading,
+previewing supported Markdown/HTML/images in a separate panel tab, and referencing
+the file in the current composer. Reference uses the same tag construction and
+inline insertion as the built-in `@` file picker, only for the current workspace.
+Reference closes a floating drawer before returning focus to the composer;
+the desktop dock stays open.
+Downloads reuse the existing bounded, owner-checked byte reader and cancellation.
+Both columns scroll independently. The tree scrolls horizontally as a whole,
+keeping indentation and complete names at deep levels. Use Pierre’s shadow-root
+CSS extension to size the virtual list by its content and prevent label shrinking. A keyboard-accessible draggable separator
+uses the shared shadcn resizable primitive to adjust their widths, preserving the
+layout across tab switches. Leave 12px below the tree. The tree can be hidden to read content in a
+narrow panel without closing the Files tab.
+
+## Ownership and lifecycle
+
+The Files tab captures workspace cwd and ID. Extend the existing artifact owner
+guard with directory reads, checking authority before and after requests. Use
+workspace-qualified SDK directory reads over REST (including ACP clients) whenever workspace IDs are advertised;
+retain the primary route only for legacy daemons. Unavailable, ambiguous,
+untrusted or changed owners fail closed. Workspace changes discard late results.
+Files panes remain mounted while inactive, preserving selection, expansion,
+source/preview mode, filtering, column sizes and scroll position across tab switches. Each pane
+checks its own workspace owner even while hidden; closing the tab or losing its
+owner discards that state. Only tab workspace identity persists across reloads. A stale persisted owner stays
+blocked, but does not hide the action for reopening the current trusted owner. File content loading retains existing size limits and cancellation.
+
+## Scope and decisions
+
+No filesystem mutations, code editing, Git operations, watchers or whole-workspace
+search index. Opening files does not add them to model context; the explicit
+Reference action inserts a file tag without sending a prompt. Keep existing
+review, attachment and file tabs unchanged. Pierre uses Shadow DOM; style its
+public variables with Web Shell semantic colors. Use its vanilla entry points to
+preserve the package's existing React 18/19 peer range. Pierre is a pinned build-time
+dependency: its vanilla implementation is bundled, so published consumers do not
+install its React peers (which require 18.3.1 or later).
+The explicit `bundledDevDependencies` list seeds license generation without
+including unrelated development tools. Bundled dependency licenses and NOTICE
+credits ship in the npm package and the VS Code companion notice file.
+Tree and source loading have local error boundaries. Failed imports offer a page
+reload only in the standalone shell when credentials survive it (or no token is
+needed). Embedded hosts and memory-only credentials instead offer Close Files,
+without reloading the host or presenting a cached import as a local retry.
+Pierre render errors propagate to the local boundary after resource cleanup.
+The constructor uses the resolved shell theme; theme changes update it in place. Floating drawers traverse shadow-root tab
+stops before Radix's light-DOM focus loop can skip the tree.
+Source rendering is virtualized; theme changes update the renderer in place. The library
+build bundles Pierre's compatible Shiki 3/4 dependency in the lazy preview chunk,
+while retaining the existing Shiki 1 dependency for other renderers; files over 10,000 lines or 1,048,576 characters use plain
+text to bound syntax-highlighting work. Files source previews refuse files above
+4 MiB before reading their content, and apply the same cap to chunked fallback
+reads. Users can download these files from the file menu. Files translations are
+excluded from the transcript-only bundle. The actual shadow tree and file menu
+have accessible names.
+
+The file menu also offers Preview for `.xlsx` files, reusing the shared spreadsheet preview in a separate workspace-scoped file tab. Opening the same file again reuses that tab; returning to Files retains the tree and inline selection. Other Excel formats retain the existing download-only behavior.
+
+## File changes assessment
+
+Pierre FileDiff can render the existing before/after text, unified/split views,
+line numbers and inline changes. It can replace the visual renderer later. The
+input may contain full snapshots, unified patches or partial edit fragments.
+Partial fragments must not be presented with full-file line numbers, and repeated
+edits to one file must retain their recorded segments. The current file-changes
+feature additionally owns tool-call grouping, aggregated
+line statistics, recorded-turn versus latest-workspace semantics, file opening,
+downloads and missing/binary file handling. Keep those responsibilities intact.
+Migrating the renderer requires separate validation of CodeMirror merge behavior,
+large/truncated changes, cancellation, themes and wrapped lines. This change only
+records the assessment; it does not migrate review rendering or connect Git.
+
+## Affected areas
+
+- Artifact panel, customization, standalone entry, translations and README.
+- App tab opening, persistence and workspace ownership wiring.
+- A workspace file browser, Pierre source renderer and focused tests.
+- Guarded artifact workspace directory reads and authority tests.
+- Browser E2E tests using the existing mock daemon, explicitly labeled as mock.
+
+## Validation and acceptance criteria
+
+1. Files appears beside File changes; initially only the tree is visible. Selecting
+   a file opens content on the left and the tree on the right.
+2. Directory expansion loads direct children and reuses cached results. Deep
+   paths and long names remain readable through horizontal tree scrolling.
+3. Selecting files changes content while keeping the tree visible.
+4. Markdown renders as a document and switches to highlighted read-only source.
+5. Filtering preserves input, shows no matches explicitly and does not load
+   directories. Refresh, empty/error and incomplete-list states are visible.
+6. Right-click copy paths, byte download, preview tabs and `@` references work.
+7. Untrusted/changed workspace owners and late responses cannot leak content.
+8. Tab switches retain file-browser state; closing/reopening, page reload tab
+   restoration and narrow layouts remain usable.
+9. Existing review and attachment behaviors remain covered.
+10. File browsing and filtering enter the PR browser smoke gate. Focused ownership,
+    persistence and transport tests, build, typecheck and inspected browser screenshots provide evidence.
+
+## Open questions and risks
+
+Trees is Beta; pin the version and validate actual expansion/model-reset behavior.
+Git badges, review migration, live watchers and global search are future work.

+
+## 问题与现状
+
+右侧拓展区提供文件更改，但无法浏览工作区文件。此次在现有操作旁新增
+「文件」入口，选中文件的内容在左侧，持续可见的目录树在右侧。
+
+## 实现方案
+
+新增可选的 `files` 右侧面板配置项及具有工作区归属的 `files` 页签，独立页面
+默认启用。空态入口和加号菜单打开或激活每个工作区唯一的文件页签。复用面板
+尺寸、关闭、全屏和持久化行为。尚未选择文件时仅显示占满宽度的目录树，点击
+文件后显示两列，初始约 70% 用于内容、30% 用于目录树，且不重建目录树；后续切换文件时目录树持续可见。
+
+采用 `@pierre/trees` 展示只读目录树，采用 `@pierre/diffs` 的 File 展示只读
+源码。保留现有 Markdown、HTML 和图片预览。Markdown 和 HTML 默认渲染预览，
+可切换源码。其他文件沿用现有文件支持及错误行为。不启用 Git 状态或编辑。
+
+通过现有 daemon API 仅加载根目录和已展开目录。Pierre 模型保存已加载路径，
+展开目录时加载直接子节点。搜索仅覆盖已加载路径，不读取因搜索而展开的目录。筛选输入保留原文，零匹配时明确
+展示「已加载路径内无匹配」。选择文件或按 Escape 结束筛选。筛选非空时优先消费 Escape，
+不会退出全屏或关闭抽屉；输入法组合期间保留原生 Escape 行为。刷新清空目录缓存，重新加载
+根目录和当前文件，并收起分支。不展示筛选范围说明和逐目录加载日志，仅在需要时
+展示可重试错误、空目录和列表截断提示。不递归展开符号链接。两列独立滚动。目录树支持整体横向滚动，保留深层缩进和完整名称；
+通过 Pierre 的 Shadow DOM CSS 扩展按内容确定虚拟列表宽度，避免名称被压缩。
+中间使用共享 shadcn 可调整尺寸组件提供
+支持键盘的拖动分隔线，切换页签保留宽度。文件树底部留出 12px。窄面板可隐藏目录树以阅读
+内容，无需关闭文件页签。文件右键菜单提供相对与绝对路径复制、下载、在独立
+页签预览 Markdown/HTML/图片，以及引用到当前输入框。引用复用内置 `@` 文件
+选择器的标签构造与行内插入，仅面向当前工作区。引用时关闭浮动抽屉，再将焦点交回输入框；
+桌面停靠面板保持展开。下载复用现有大小受限、具有
+归属检查和取消支持的字节读取流程。
+
+## 归属与生命周期
+
+文件页签保存工作区 cwd 和 ID。扩展现有产物工作区权限守卫，目录请求前后均
+校验归属。daemon 公布工作区 ID 时通过具有工作区限定的 SDK REST 接口读取目录（包括 ACP 客户端）；
+仅旧 daemon 保留主工作区接口。不可用、歧义、不可信或已变更的归属均拒绝访问。
+切换工作区后丢弃迟到结果。文件页签未激活时仍保持挂载，切换页签保留选中、
+展开、源码/预览模式、筛选、列宽和滚动位置。隐藏页签仍独立校验工作区归属；关闭页签
+或归属失效时丢弃状态。页面刷新仅恢复页签工作区身份。旧归属页签继续拒绝访问，但不遮蔽重新打开当前可信
+归属的入口。
+文件内容加载保留现有大小限制和取消行为。
+
+## 范围与决策
+
+不实现文件系统修改、代码编辑、Git 操作、监听器或全工作区搜索索引。打开文件
+不会自动加入模型上下文；显式「引用」仅插入文件标签，不发送请求。保留现有审查、附件和文件页签行为。Pierre 使用
+Shadow DOM，通过公开变量适配 Web Shell 语义颜色。使用原生入口以保留包现有
+React 18/19 peer 范围。Pierre 固定版本并作为构建期依赖，原生实现完整打包，
+发布包的使用方无需安装其要求 18.3.1 起的 React peer。
+显式 `bundledDevDependencies` 清单作为许可证生成种子，不包含无关开发工具。
+打包依赖的许可证与 NOTICE 署名同时进入 npm 发布包和 VS Code 扩展声明文件。
+文件树与源码加载各有局部错误边界。导入失败时，仅独立页面在凭据可恢复或不需要 token 时提供页面重载；
+嵌入宿主和仅保存在内存中的凭据改为提供「关闭文件」，不重载宿主，也不把缓存的导入失败伪装成本地重试。
+Pierre 渲染错误在释放资源后进入局部边界；构造时即使用当前 Web Shell 主题，后续原地更新。浮动抽屉遍历 Shadow DOM 中的 Tab 焦点，
+防止 Radix 仅遍历普通 DOM 的焦点循环跳过文件树。
+源码采用虚拟滚动；切换主题原地更新渲染器。库构建将 Pierre 兼容的 Shiki 3/4
+依赖打包进延迟预览模块，其他渲染器保留现有 Shiki 1 依赖；超过 10,000 行或 1,048,576 字符时使用纯文本，以限制语法高亮开销。文件树的源码预览在读取内容前拒绝超过 4 MiB 的文件，分块回退读取也使用同一上限；
+用户仍可通过文件菜单下载。Files 文案不进入只读 transcript 包；实际 Shadow DOM 文件树和文件菜单均有可访问名称。
+
+文件右键菜单也为 `.xlsx` 提供「预览」，复用共享表格预览，在独立且绑定工作区的文件页签中打开。同一文件重复打开复用页签，返回「文件」保留目录树和内联选中。其他 Excel 格式沿用现有的仅下载行为。
+
+## 文件更改承载评估
+
+Pierre FileDiff 可展示现有修改前后文本、合并或双栏视图、行号和行内变更，后续
+可替换显示层。输入可能是完整快照、统一补丁或局部编辑片段。局部片段不能展示为
+完整文件的真实行号，同一文件的多次编辑也必须保留记录的分段。目前文件更改还
+负责工具调用分组、汇总行数统计、历史轮次与最新
+工作区语义、打开文件、下载及缺失或二进制文件处理，这些职责应继续保留。
+迁移渲染器需要单独验证 CodeMirror merge 行为、大型及截断变更、取消、主题和
+折行。本次仅记录评估，不迁移审查渲染，也不接入 Git。
+
+## 影响范围
+
+- 产物面板、配置类型、独立入口、翻译和 README。
+- App 页签打开、持久化及工作区归属连接。
+- 工作区文件浏览器、Pierre 源码渲染器及针对性测试。
+- 具有权限守卫的产物工作区目录读取与归属测试。
+- 使用现有模拟 daemon 的浏览器 E2E 测试，明确标注模拟环境。
+
+## 验证与验收标准
+
+1. 「文件」与「文件更改」并列，初始仅显示目录树；选择文件后显示左侧内容、右侧目录树。
+2. 展开目录读取直接子节点并复用缓存；深层路径和长名称可通过目录树横向滚动完整阅读。
+3. 选择不同文件切换内容，目录树持续可见。
+4. Markdown 显示文档，可切换高亮只读源码。
+5. 筛选保留输入、明确展示零匹配且不加载目录；刷新、空态、错误和不完整列表提示可见。
+6. 右键路径复制、字节下载、独立预览和 `@` 引用均可用。
+7. 不可信或已变更的工作区归属及迟到响应不能泄露内容。
+8. 切换页签保留文件浏览状态；面板关闭重开、页面刷新恢复页签和窄布局保持可用。
+9. 现有审查与附件行为有回归覆盖。
+10. 文件浏览与筛选进入 PR 浏览器 smoke 门禁；归属、持久化与传输针对性测试、构建、
+    类型检查及目视检查浏览器截图提供验证证据。
+
+## 未决问题与风险
+
+Trees 仍处于 Beta，固定版本并验证真实的展开及模型重置行为。
+Git 标记、审查迁移、实时监听和全局搜索留待后续。

+    "Derivative Works" shall mean any work, whether in Source or Object form,
+    that is based on (or derived from) the Work and for which the editorial
+    revisions, annotations, elaborations, or other modifications represent, as a

+    Derivative Works shall not include works that remain separable from, or
+    merely link (or bind by name) to the interfaces of, the Work and Derivative
+    Works thereof.

+    Contribution."
+
+    "Contributor" shall mean Licensor and any individual or Legal Entity on
+    behalf of whom a Contribution has been received by Licensor and subsequently

+
+2.  Grant of Copyright License. Subject to the terms and conditions of this
+    License, each Contributor hereby grants to You a perpetual, worldwide,
+    non-exclusive, no-charge, royalty-free, irrevocable copyright license to
+    reproduce, prepare Derivative Works of, publicly display, publicly perform,
+    sublicense, and distribute the Work and such Derivative Works in Source or
+    Object form.
+
+3.  Grant of Patent License. Subject to the terms and conditions of this
+    License, each Contributor hereby grants to You a perpetual, worldwide,
+    non-exclusive, no-charge, royalty-free, irrevocable (except as stated in
+    this section) patent license to make, have made, use, offer to sell, sell,
+    import, and otherwise transfer the Work, where such license applies only to
+    those patent claims licensable by such Contributor that are necessarily
+    infringed by their Contribution(s) alone or by combination of their
+    Contribution(s) with the Work to which such Contribution(s) was submitted.
+    If You institute patent litigation against any entity (including a
+    cross-claim or counterclaim in a lawsuit) alleging that the Work or a
+    Contribution incorporated within the Work constitutes direct or contributory
+    patent infringement, then any patent licenses granted to You under this
+    License for that Work shall terminate as of the date such litigation is
+    filed.
+
+4.  Redistribution. You may reproduce and distribute copies of the Work or
+    Derivative Works thereof in any medium, with or without modifications, and
+    in Source or Object form, provided that You meet the following conditions:
+
+    (a) You must give any other recipients of the Work or Derivative Works a
+    copy of this License; and
+
+    (b) You must cause any modified files to carry prominent notices stating
+    that You changed the files; and
+
+    (c) You must retain, in the Source form of any Derivative Works that You
+    distribute, all copyright, patent, trademark, and attribution notices from
+    the Source form of the Work, excluding those notices that do not pertain to
+    any part of the Derivative Works; and
+
+    (d) If the Work includes a "NOTICE" text file as part of its distribution,
+    then any Derivative Works that You distribute must include a readable copy
+    of the attribution notices contained within such NOTICE file, excluding
+    those notices that do not pertain to any part of the Derivative Works, in at
+    least one of the following places: within a NOTICE text file distributed as
+    part of the Derivative Works; within the Source form or documentation, if
+    provided along with the Derivative Works; or, within a display generated by
+    the Derivative Works, if and wherever such third-party notices normally
+    appear. The contents of the NOTICE file are for informational purposes only
+    and do not modify the License. You may add Your own attribution notices
+    within Derivative Works that You distribute, alongside or as an addendum to
+    the NOTICE text from the Work, provided that such additional attribution
+    notices cannot be construed as modifying the License.
+
+    You may add Your own copyright statement to Your modifications and may
+    provide additional or different license terms and conditions for use,
+    reproduction, or distribution of Your modifications, or for any such
+    Derivative Works as a whole, provided Your use, reproduction, and
+    distribution of the Work otherwise complies with the conditions stated in
+    this License.
+
+5.  Submission of Contributions. Unless You explicitly state otherwise, any
+    Contribution intentionally submitted for inclusion in the Work by You to the
+    Licensor shall be under the terms and conditions of this License, without
+    any additional terms or conditions. Notwithstanding the above, nothing
+    herein shall supersede or modify the terms of any separate license agreement
+    you may have executed with Licensor regarding such Contributions.
+
+6.  Trademarks. This License does not grant permission to use the trade names,
+    trademarks, service marks, or product names of the Licensor, except as
+    required for reasonable and customary use in describing the origin of the
+    Work and reproducing the content of the NOTICE file.
+
+7.  Disclaimer of Warranty. Unless required by applicable law or agreed to in
+    writing, Licensor provides the Work (and each Contributor provides its
+    Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+    KIND, either express or implied, including, without limitation, any
+    warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or
+    FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for determining
+    the appropriateness of using or redistributing the Work and assume any risks
+    associated with Your exercise of permissions under this License.
+
+8.  Limitation of Liability. In no event and under no legal theory, whether in
+    tort (including negligence), contract, or otherwise, unless required by
+    applicable law (such as deliberate and grossly negligent acts) or agreed to
+    in writing, shall any Contributor be liable to You for damages, including
+    any direct, indirect, special, incidental, or consequential damages of any
+    character arising as a result of this License or out of the use or inability
+    to use the Work (including but not limited to damages for loss of goodwill,
+    work stoppage, computer failure or malfunction, or any and all other
+    commercial damages or losses), even if such Contributor has been advised of
+    the possibility of such damages.
+
+9.  Accepting Warranty or Additional Liability. While redistributing the Work or
+    Derivative Works thereof, You may choose to offer, and charge a fee for,
+    acceptance of support, warranty, indemnity, or other liability obligations
+    and/or rights consistent with this License. However, in accepting such
+    obligations, You may act only on Your own behalf and on Your sole
+    responsibility, not on behalf of any other Contributor, and only if You
+    agree to indemnify, defend, and hold each Contributor harmless for any
+    liability incurred by, or claims asserted against, such Contributor by
+    reason of your accepting any such warranty or additional liability.

+    associated with Your exercise of permissions under this License.
+
+8.  Limitation of Liability. In no event and under no legal theory, whether in
+    tort (including negligence), contract, or otherwise, unless required by
+    applicable law (such as deliberate and grossly negligent acts) or agreed to
+    in writing, shall any Contributor be liable to You for damages, including

+    agree to indemnify, defend, and hold each Contributor harmless for any
+    liability incurred by, or claims asserted against, such Contributor by
+    reason of your accepting any such warranty or additional liability.

+    distribute, all copyright, patent, trademark, and attribution notices from
+    the Source form of the Work, excluding those notices that do not pertain to

+5.  Submission of Contributions. Unless You explicitly state otherwise, any

+    responsibility, not on behalf of any other Contributor, and only if You
+    agree to indemnify, defend, and hold each Contributor harmless for any
+    liability incurred by, or claims asserted against, such Contributor by

+--- NOTICE ---
+
+This project includes some code derived from
+[@headless-tree/core](https://github.com/lukasbach/headless-tree).
+
+The initial version of this project used `headless-tree` as the underlying tree
+implementation. We have since written our own core at `packages/path-store`, but
+many of the best ideas from `headless-tree` made their way to `path-store` and
+`trees`. It's hard to identify exactly which code this is at this point, but
+definitely things like the drag and drop implementation and the general list
+approach to rendering and I'm sure more. The work that `@lukasbach` has
+contributed to this space is greatly appreciated. `<3`

+    License, each Contributor hereby grants to You a perpetual, worldwide,
+    non-exclusive, no-charge, royalty-free, irrevocable copyright license to
+    reproduce, prepare Derivative Works of, publicly display, publicly perform,

+
+3.  Grant of Patent License. Subject to the terms and conditions of this
+    License, each Contributor hereby grants to You a perpetual, worldwide,
+    non-exclusive, no-charge, royalty-free, irrevocable (except as stated in
+    this section) patent license to make, have made, use, offer to sell, sell,

+    Contribution(s) with the Work to which such Contribution(s) was submitted.
+    If You institute patent litigation against any entity (including a
+    cross-claim or counterclaim in a lawsuit) alleging that the Work or a
+    Contribution incorporated within the Work constitutes direct or contributory
+    patent infringement, then any patent licenses granted to You under this
+    License for that Work shall terminate as of the date such litigation is
+    filed.
+
+4.  Redistribution. You may reproduce and distribute copies of the Work or
+    Derivative Works thereof in any medium, with or without modifications, and
+    in Source or Object form, provided that You meet the following conditions:
+
+    (a) You must give any other recipients of the Work or Derivative Works a
+    copy of this License; and
+
+    (b) You must cause any modified files to carry prominent notices stating
+    that You changed the files; and
+
+    (c) You must retain, in the Source form of any Derivative Works that You
+    distribute, all copyright, patent, trademark, and attribution notices from
+    the Source form of the Work, excluding those notices that do not pertain to
+    any part of the Derivative Works; and
+
+    (d) If the Work includes a "NOTICE" text file as part of its distribution,
+    then any Derivative Works that You distribute must include a readable copy
+    of the attribution notices contained within such NOTICE file, excluding
+    those notices that do not pertain to any part of the Derivative Works, in at
+    least one of the following places: within a NOTICE text file distributed as
+    part of the Derivative Works; within the Source form or documentation, if
+    provided along with the Derivative Works; or, within a display generated by
+    the Derivative Works, if and wherever such third-party notices normally
+    appear. The contents of the NOTICE file are for informational purposes only
+    and do not modify the License. You may add Your own attribution notices
+    within Derivative Works that You distribute, alongside or as an addendum to
+    the NOTICE text from the Work, provided that such additional attribution
+    notices cannot be construed as modifying the License.
+
+    You may add Your own copyright statement to Your modifications and may
+    provide additional or different license terms and conditions for use,
+    reproduction, or distribution of Your modifications, or for any such
+    Derivative Works as a whole, provided Your use, reproduction, and
+    distribution of the Work otherwise complies with the conditions stated in
+    this License.
+
+5.  Submission of Contributions. Unless You explicitly state otherwise, any
+    Contribution intentionally submitted for inclusion in the Work by You to the
+    Licensor shall be under the terms and conditions of this License, without
+    any additional terms or conditions. Notwithstanding the above, nothing
+    herein shall supersede or modify the terms of any separate license agreement
+    you may have executed with Licensor regarding such Contributions.
+
+6.  Trademarks. This License does not grant permission to use the trade names,
+    trademarks, service marks, or product names of the Licensor, except as
+    required for reasonable and customary use in describing the origin of the
+    Work and reproducing the content of the NOTICE file.
+
+7.  Disclaimer of Warranty. Unless required by applicable law or agreed to in
+    writing, Licensor provides the Work (and each Contributor provides its
+    Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+    KIND, either express or implied, including, without limitation, any
+    warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or
+    FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for determining
+    the appropriateness of using or redistributing the Work and assume any risks
+    associated with Your exercise of permissions under this License.
+
+8.  Limitation of Liability. In no event and under no legal theory, whether in
+    tort (including negligence), contract, or otherwise, unless required by
+    applicable law (such as deliberate and grossly negligent acts) or agreed to
+    in writing, shall any Contributor be liable to You for damages, including
+    any direct, indirect, special, incidental, or consequential damages of any
+    character arising as a result of this License or out of the use or inability
+    to use the Work (including but not limited to damages for loss of goodwill,
+    work stoppage, computer failure or malfunction, or any and all other
+    commercial damages or losses), even if such Contributor has been advised of
+    the possibility of such damages.
+
+9.  Accepting Warranty or Additional Liability. While redistributing the Work or
+    Derivative Works thereof, You may choose to offer, and charge a fee for,
+    acceptance of support, warranty, indemnity, or other liability obligations
+    and/or rights consistent with this License. However, in accepting such
+    obligations, You may act only on Your own behalf and on Your sole
+    responsibility, not on behalf of any other Contributor, and only if You
+    agree to indemnify, defend, and hold each Contributor harmless for any
+    liability incurred by, or claims asserted against, such Contributor by
+    reason of your accepting any such warranty or additional liability.

+    "Derivative Works" shall mean any work, whether in Source or Object form,
+    that is based on (or derived from) the Work and for which the editorial
+    revisions, annotations, elaborations, or other modifications represent, as a

+    Contribution."
+
+    "Contributor" shall mean Licensor and any individual or Legal Entity on
+    behalf of whom a Contribution has been received by Licensor and subsequently
+    incorporated within the Work.
+
+2.  Grant of Copyright License. Subject to the terms and conditions of this
+    License, each Contributor hereby grants to You a perpetual, worldwide,
+    non-exclusive, no-charge, royalty-free, irrevocable copyright license to
+    reproduce, prepare Derivative Works of, publicly display, publicly perform,
+    sublicense, and distribute the Work and such Derivative Works in Source or
+    Object form.
+
+3.  Grant of Patent License. Subject to the terms and conditions of this
+    License, each Contributor hereby grants to You a perpetual, worldwide,
+    non-exclusive, no-charge, royalty-free, irrevocable (except as stated in
+    this section) patent license to make, have made, use, offer to sell, sell,
+    import, and otherwise transfer the Work, where such license applies only to
+    those patent claims licensable by such Contributor that are necessarily
+    infringed by their Contribution(s) alone or by combination of their
+    Contribution(s) with the Work to which such Contribution(s) was submitted.
+    If You institute patent litigation against any entity (including a
+    cross-claim or counterclaim in a lawsuit) alleging that the Work or a
+    Contribution incorporated within the Work constitutes direct or contributory
+    patent infringement, then any patent licenses granted to You under this
+    License for that Work shall terminate as of the date such litigation is
+    filed.
+
+4.  Redistribution. You may reproduce and distribute copies of the Work or
+    Derivative Works thereof in any medium, with or without modifications, and
+    in Source or Object form, provided that You meet the following conditions:
+
+    (a) You must give any other recipients of the Work or Derivative Works a
+    copy of this License; and
+
+    (b) You must cause any modified files to carry prominent notices stating
+    that You changed the files; and
+
+    (c) You must retain, in the Source form of any Derivative Works that You
+    distribute, all copyright, patent, trademark, and attribution notices from
+    the Source form of the Work, excluding those notices that do not pertain to
+    any part of the Derivative Works; and
+
+    (d) If the Work includes a "NOTICE" text file as part of its distribution,
+    then any Derivative Works that You distribute must include a readable copy
+    of the attribution notices contained within such NOTICE file, excluding
+    those notices that do not pertain to any part of the Derivative Works, in at
+    least one of the following places: within a NOTICE text file distributed as
+    part of the Derivative Works; within the Source form or documentation, if
+    provided along with the Derivative Works; or, within a display generated by
+    the Derivative Works, if and wherever such third-party notices normally
+    appear. The contents of the NOTICE file are for informational purposes only
+    and do not modify the License. You may add Your own attribution notices
+    within Derivative Works that You distribute, alongside or as an addendum to
+    the NOTICE text from the Work, provided that such additional attribution
+    notices cannot be construed as modifying the License.
+
+    You may add Your own copyright statement to Your modifications and may
+    provide additional or different license terms and conditions for use,
+    reproduction, or distribution of Your modifications, or for any such
+    Derivative Works as a whole, provided Your use, reproduction, and
+    distribution of the Work otherwise complies with the conditions stated in
+    this License.
+
+5.  Submission of Contributions. Unless You explicitly state otherwise, any
+    Contribution intentionally submitted for inclusion in the Work by You to the
+    Licensor shall be under the terms and conditions of this License, without
+    any additional terms or conditions. Notwithstanding the above, nothing
+    herein shall supersede or modify the terms of any separate license agreement
+    you may have executed with Licensor regarding such Contributions.
+
+6.  Trademarks. This License does not grant permission to use the trade names,
+    trademarks, service marks, or product names of the Licensor, except as
+    required for reasonable and customary use in describing the origin of the
+    Work and reproducing the content of the NOTICE file.
+
+7.  Disclaimer of Warranty. Unless required by applicable law or agreed to in
+    writing, Licensor provides the Work (and each Contributor provides its
+    Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+    KIND, either express or implied, including, without limitation, any
+    warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or
+    FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for determining
+    the appropriateness of using or redistributing the Work and assume any risks
+    associated with Your exercise of permissions under this License.
+
+8.  Limitation of Liability. In no event and under no legal theory, whether in
+    tort (including negligence), contract, or otherwise, unless required by
+    applicable law (such as deliberate and grossly negligent acts) or agreed to
+    in writing, shall any Contributor be liable to You for damages, including
+    any direct, indirect, special, incidental, or consequential damages of any
+    character arising as a result of this License or out of the use or inability
+    to use the Work (including but not limited to damages for loss of goodwill,
+    work stoppage, computer failure or malfunction, or any and all other
+    commercial damages or losses), even if such Contributor has been advised of

+    associated with Your exercise of permissions under this License.
+
+8.  Limitation of Liability. In no event and under no legal theory, whether in
+    tort (including negligence), contract, or otherwise, unless required by
+    applicable law (such as deliberate and grossly negligent acts) or agreed to
+    in writing, shall any Contributor be liable to You for damages, including

+--- NOTICE ---
+
+This project includes some code derived from
+[@headless-tree/core](https://github.com/lukasbach/headless-tree).
+
+The initial version of this project used `headless-tree` as the underlying tree
+implementation. We have since written our own core at `packages/path-store`, but
+many of the best ideas from `headless-tree` made their way to `path-store` and
+`trees`. It's hard to identify exactly which code this is at this point, but
+definitely things like the drag and drop implementation and the general list
+approach to rendering and I'm sure more. The work that `@lukasbach` has
+contributed to this space is greatly appreciated. `<3`

+    provided along with the Derivative Works; or, within a display generated by
+    the Derivative Works, if and wherever such third-party notices normally
+    appear. The contents of the NOTICE file are for informational purposes only
+    and do not modify the License. You may add Your own attribution notices
+    within Derivative Works that You distribute, alongside or as an addendum to
+    the NOTICE text from the Work, provided that such additional attribution
+    notices cannot be construed as modifying the License.
+
+    You may add Your own copyright statement to Your modifications and may
+    provide additional or different license terms and conditions for use,
+    reproduction, or distribution of Your modifications, or for any such
+    Derivative Works as a whole, provided Your use, reproduction, and

+
+5.  Submission of Contributions. Unless You explicitly state otherwise, any
+    Contribution intentionally submitted for inclusion in the Work by You to the

+    FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for determining
+    the appropriateness of using or redistributing the Work and assume any risks
+    associated with Your exercise of permissions under this License.
+
+8.  Limitation of Liability. In no event and under no legal theory, whether in
+    tort (including negligence), contract, or otherwise, unless required by
+    applicable law (such as deliberate and grossly negligent acts) or agreed to
+    in writing, shall any Contributor be liable to You for damages, including
+    any direct, indirect, special, incidental, or consequential damages of any

+9.  Accepting Warranty or Additional Liability. While redistributing the Work or
+    Derivative Works thereof, You may choose to offer, and charge a fee for,
+    acceptance of support, warranty, indemnity, or other liability obligations
+    and/or rights consistent with this License. However, in accepting such
+    obligations, You may act only on Your own behalf and on Your sole
+    responsibility, not on behalf of any other Contributor, and only if You
+    agree to indemnify, defend, and hold each Contributor harmless for any
+    liability incurred by, or claims asserted against, such Contributor by
+    reason of your accepting any such warranty or additional liability.
