+# Agent Note: Plugin market Discover page and index reader
+
+Status: implemented
+
+English | [中文](2026-10-02-plugin-market-discover.zh.md)
+
+## Problem
+
+The [plugin market index format](2026-10-02-plugin-market-index-format.md) lets a market publish installable bundles in one document, but DSH needs a reader that fetches indexes safely, a place where users choose index sources and browse entries, and a path from an entry to the existing installation flow. No official market exists, so DSH cannot ship a default source; the sources are user data.
+
+The plugin manager owns profile package operations and must not remount while an installation runs. Market configuration that a user edits from the Web therefore cannot be an ordinary configuration field of `plugin-manager`.
+
+## Decision
+
+The feature ships as the experimental optional [custom plugin markets bundle](../../../../packages/experimental/plugin-market-bundle/README.md), off by default, which mounts both rows below; with it off, neither the service, the Discover tab, nor the `plugin_market` tool exists, and the Plugins page shows no tabs. A separate Host service, [`pluginMarket`](../../../../packages/boot/plugin-market/README.md), reads indexes. It requires `pluginManager` for read-only calls and never writes the profile. Its `indexes` configuration field is volatile: Settings writes only volatile fields, and the Loader commits a volatile-only change into the running reference without remounting any plugin. Other fields (`fetchTimeoutMs`, `maxBytes`, `cacheTtlMs`) are ordinary configuration.
+
+Index URLs use `http:` or `https:`, without credentials or fragment. `file:` is excluded because relative icon references would resolve to URLs a browser cannot load. `search` and `entry` accept only a configured URL, so the Host never fetches an address a client supplies. The Host fetches through the process proxy, refuses redirects, bounds the body, and validates with the shared format package; an invalid index affects only its own URL.
+
+Indexes can reach the default 128 MiB `maxBytes`, so clients never receive or filter a whole index. `search` filters, matches text, orders, and pages on the Host and returns at most 100 entries; `entry` returns one plugin by name for the tool. Text matching is fuzzy and covers the package name, author, keywords, and every language of the title, description, and category and label titles, because a person may search in any language a market writes. A Chinese, Japanese, or Korean run is indexed as overlapping character pairs and its last character, so queries match without a word dictionary. [MiniSearch](https://github.com/lucaong/minisearch) builds the text index on the first text query of each document and yields between chunks. Each page carries its document's `fetchedAt`, and a later page sent with it is answered from that document while it is cached, so paging stays consistent across cache expiry; a client whose document was replaced starts again from the first page.
+
+Each returned entry carries the profile's installation status, its compatibility computed by `evaluatePluginCompatibility` with the profile's version exemptions, and `install`, the exact arguments from `marketInstallTarget`. That is the only place install arguments are built; the Web page and the model tool consume it.
+
+The Web [Discover tab](../../../../packages/client/ui-plugin-market/README.md) is its own client plugin. [`ui-plugin-manager`](../../../../packages/client/ui-plugin-manager/README.md) declares a `plugins.tab` slot and shows **Installed** and each contributed tab under the page header, because browsing a market and managing installed bundles are separate tasks of equal rank. The owner props provide `install(spec, registry?)` for a spec the person confirmed in the tab, which opens the existing install dialog at its check screen without the spec form, and `openPackage(name)`, which opens an installed bundle's page. A registry an entry names applies to that install only and is never remembered as the dialog's choice, so one market cannot redirect later manual installs. Discover confirms each install with the entry's origin and a trust notice, and keeps source management, which adds a code origin, in a dialog with its own trust notice. Each entry has a page with its full description, source facts, and every listed version; **Install** on a card chooses the default version, and the page can install any other version installation accepts. Indexes are browsed one at a time; categories, labels, and sort keys stay opaque and display in localized title order; entries missing the selected sort value come last in both directions.
+
+A read-only `plugin_market` tool lists indexes and pages entries, returning the `target` and `registry` that `plugin_manager`'s `install_bundle` accepts. It requires no approval; installation keeps `plugin_manager`'s approval. The tool cannot change index sources, because adding a source introduces a new code origin.
+
+## Alternatives considered
+
+**Market fields on `plugin-manager`.** A non-volatile field would remount `plugin-manager` when the Web edits it and interrupt package operations it owns. Even with a volatile field, a separate service guarantees that market configuration never reaches `plugin-manager`, at the cost of one more package and service.
+
+**Configuring indexes only in `cordis.yml`.** Most users do not edit `cordis.yml`, so Discover would stay empty for them.
+
+**Fetching indexes in the browser.** CORS, the Host's proxy configuration, and validation where untrusted data enters favor Host fetches.
+
+**Filtering in the browser.** It needs the whole annotated index in every client, which grows with the index and recomputes compatibility for every entry on each read.
+
+**A query protocol on the index host.** It would keep large indexes off the Host but requires a server for every market, which a static index file avoids. It remains the next step if indexes outgrow the Host.
+
+**Merging all configured indexes into one list.** Opaque ids from different markets may collide with different meanings, and duplicate package names need a conflict rule. Per-index browsing avoids both.
+
+**Rendering Discover inside `ui-plugin-manager`.** The page would depend on the market Remote and grow further; a slot keeps the page usable without the market and lets the market plugin own its copy and state.
+
+**Discover as a section under the Installed groups, installing through the spec form.** Finding it requires scrolling past every installed bundle, and the form asks a person to review a spec they never typed. Tabs give browsing its own entry point, and a confirmation with the entry's origin followed by the check screen replaces the form.
+
+**An approval for `plugin_market`.** Listing changes nothing and reads only sources the user configured; requiring approval would add a prompt without protecting an operation. The installation step keeps its approval.
+
+**An upgrade action.** Upgrading changes the documented "uninstall, then install" behavior and is deferred; Discover shows `update-available` as a status.
+
+## Consequences
+
+- Users browse and install third-party bundles without knowing a spec, and the existing install dialog, registry fallback, build-script approval, and compatibility refusal apply unchanged.
+- The Settings form also shows `indexes`, because Settings lists every volatile field.
+- An `http:` index, including the install specs it lists, can be altered in transit; a market reached over an untrusted network needs `https:`.
+- URL icons are requested by the browser and disclose the user's IP address to image hosts; Discover loads them without a referrer.
+- Market text reaches users and, through `plugin_market`, models; the tool description marks it as third-party content.
+- A real-composition test proves that `setIndexes` persists through the profile without remounting the service, and unit tests cover fetch limits, cache sharing, removal, and search matching, ordering, and paging.

+# Agent Note: 插件市场发现页与索引读取器
+
+Status: implemented
+
+[English](2026-10-02-plugin-market-discover.md) | 中文
+
+## 问题
+
+[插件市场索引格式](2026-10-02-plugin-market-index-format.zh.md)让市场能在一份文档中发布可安装的组合包（bundle），但 DSH 还需要：一个安全获取索引的读取器，一个让用户选择索引源并浏览条目的位置，以及一条从条目进入现有安装流程的路径。目前没有官方市场，因此 DSH 无法随附默认源；索引源属于用户数据。
+
+插件管理器拥有 profile 的包操作，安装运行期间不得重新挂载。因此，用户从 Web 编辑的市场配置不能是 `plugin-manager` 的普通配置字段。
+
+## 决策
+
+该功能以实验性的可选[自定义插件市场组合包](../../../../packages/experimental/plugin-market-bundle/README.zh.md)发布，默认关闭，并挂载下面两行；关闭时，服务、「发现」标签页和 `plugin_market` 工具都不存在，插件页也不显示标签页。由独立的 Host 服务 [`pluginMarket`](../../../../packages/boot/plugin-market/README.zh.md) 读取索引。它依赖 `pluginManager` 进行只读调用，从不写入 profile。它的 `indexes` 配置字段是 volatile 字段：Settings 只写入 volatile 字段，Loader 把只涉及 volatile 字段的变更提交到运行中的引用，不重新挂载任何插件。其他字段（`fetchTimeoutMs`、`maxBytes`、`cacheTtlMs`）是普通配置。
+
+索引 URL 使用 `http:` 或 `https:`，不含凭据或片段。排除 `file:`，因为相对图标引用会解析为浏览器无法加载的 URL。`search` 和 `entry` 只接受已配置的 URL，因此 Host 从不获取客户端提供的地址。Host 通过进程代理获取，拒绝重定向，限制响应体大小，并用共享的格式包校验；无效索引只影响它自己的 URL。
+
+索引可能达到默认 128 MiB 的 `maxBytes`，因此客户端从不接收或过滤整个索引。`search` 在 Host 上完成过滤、文本匹配、排序和分页，最多返回 100 个条目；`entry` 按名称为工具返回一个插件。文本匹配是模糊的，覆盖包名、作者、关键词，以及标题、描述、分类标题和标签标题的所有语言，因为用户可能使用市场所写的任意语言搜索。中文、日文或韩文片段被索引为相邻的两字组合及其最后一个字符，因此查询无需分词词典即可匹配。[MiniSearch](https://github.com/lucaong/minisearch) 在每份文档第一次带文本的查询时构建文本索引，并在分块之间让出事件循环。每页都携带其文档的 `fetchedAt`，之后带着它发送的页请求只要该文档仍在缓存中就用它回答，因此分页在缓存过期后仍保持一致；文档被替换的客户端从第一页重新开始。
+
+每个返回的条目携带 profile 中的安装状态、由 `evaluatePluginCompatibility` 结合 profile 版本豁免计算出的兼容性，以及 `install`，即 `marketInstallTarget` 给出的精确参数。这是唯一构建安装参数的位置；Web 页面和模型工具都使用它。
+
+Web 的[发现标签页](../../../../packages/client/ui-plugin-market/README.zh.md)是独立的 Client 插件。[`ui-plugin-manager`](../../../../packages/client/ui-plugin-manager/README.zh.md) 声明 `plugins.tab` slot，并在页头下方显示**已安装**和每个贡献的标签页，因为浏览市场与管理已安装组合包是两项同等重要的独立任务。owner props 提供 `install(spec, registry?)` 和 `openPackage(name)`：前者用于用户已在标签页中确认的 spec，在检查界面打开现有的安装对话框，不显示 spec 表单；后者打开已安装组合包的页面。条目指定的注册表只用于这一次安装，从不作为对话框的选择被记住，因此一个市场无法改变之后手动安装所用的注册表。发现标签页在每次安装前显示条目来源和信任提示以供确认，并把会引入代码来源的索引源管理放在带有自身信任提示的对话框中。每个条目都有一个页面，显示其完整描述、来源信息和列出的每个版本；卡片上的**安装**选择默认版本，页面可以安装安装检查接受的任何其他版本。索引一次浏览一个；分类、标签和排序键保持不透明，按本地化标题顺序显示；缺少所选排序值的条目在两个方向上都排在最后。
+
+只读的 `plugin_market` 工具列出索引并分页列出条目，返回 `plugin_manager` 的 `install_bundle` 接受的 `target` 和 `registry`。它不需要批准；安装仍保留 `plugin_manager` 的批准。该工具不能修改索引源，因为添加索引源会引入新的代码来源。
+
+## 考虑过的替代方案
+
+**把市场字段放在 `plugin-manager` 上。** 非 volatile 字段在 Web 编辑它时会重新挂载 `plugin-manager`，中断它拥有的包操作。即使使用 volatile 字段，独立服务也能保证市场配置永远不会到达 `plugin-manager`，代价是多一个包和服务。
+
+**只在 `cordis.yml` 中配置索引。** 大多数用户不编辑 `cordis.yml`，发现区对他们会一直为空。
+
+**在浏览器中获取索引。** CORS、Host 的代理配置，以及在不可信数据进入处进行校验，都支持由 Host 获取。
+
+**在浏览器中过滤。** 这需要每个客户端都拿到整个带注解的索引，其大小随索引增长，并且每次读取都要为每个条目重新计算兼容性。
+
+**在索引主机上提供查询协议。** 它能让大索引不进入 Host，但每个市场都需要一台服务器，而静态索引文件不需要。如果索引超出 Host 的承受能力，这是下一步。
+
+**把所有已配置索引合并成一个列表。** 不同市场的不透明 id 可能相同但含义不同，重复的包名也需要冲突规则。按索引分别浏览可以避免这两个问题。
+
+**在 `ui-plugin-manager` 内渲染发现区。** 该页面会依赖市场 Remote，代码量也会继续增加；使用 slot 时，没有市场该页面仍可使用，市场插件也能拥有自己的文案和状态。
+
+**把发现作为「已安装」分组下方的区域，并通过 spec 表单安装。** 找到它需要滚动经过每个已安装组合包，而且该表单要求用户审核一个自己从未输入的 spec。标签页为浏览提供独立入口，先显示条目来源以供确认、再进入检查界面的流程取代了该表单。
+
+**为 `plugin_market` 要求批准。** 列出操作不做任何改动，只读取用户配置的源；要求批准只会增加一次提示，而不保护任何操作。安装步骤保留其批准。
+
+**升级操作。** 升级会改变已记录的「先卸载再安装」行为，因此延后；发现区把 `update-available` 显示为状态。
+
+## 后果
+
+- 用户无需知道 spec 即可浏览并安装第三方组合包，现有的安装对话框、registry 回退、构建脚本批准和兼容性拒绝照常适用。
+- 设置表单也显示 `indexes`，因为设置会列出每个 volatile 字段。
+- `http:` 索引（包括其中列出的安装 spec）可能在传输途中被篡改；经由不可信网络访问的市场需要使用 `https:`。
+- URL 图标由浏览器请求，会向图片主机暴露用户的 IP 地址；发现区加载图标时不发送 referrer。
+- 市场文本会到达用户，并通过 `plugin_market` 到达模型；工具描述将其标记为第三方内容。
+- 一个真实组合测试证明 `setIndexes` 会经由 profile 持久化而不重新挂载服务，单元测试覆盖获取限制、缓存共享、移除，以及搜索的匹配、排序和分页。

 - A validator accepts the example above and rejects one violation of each rule in Root fields, Plugin fields, Version fields, and the `source` forms, with a diagnostic naming the JSON path.
 - Install arguments built from every example version are accepted by DSH's install-spec parser and by pnpm.

 A profile directory holds a `package.json` (out-of-tree plugin dependencies plus the profile manifest `dsh.profile` with its ordered `bundles` list) and a `cordis.patch.yml` (the user's own patch layer). `dsh-hmr`, when enabled in YAML, watches the profile manifest and both profile and home patch files, then recomposes all layers through one serialized reload. Without HMR, changes apply on restart. Edits arriving during watcher registration use the same nonfatal reload reporting as later edits. [Plugin Manager](../../packages/boot/plugin-manager/README.md) shares package operations and the profile write lock with `dsh plugin`; package updates retain disabled bundle selections. CLI package commands inherit authentication variables and terminal descriptors, including interactive build approval; service calls retain their scrubbed environment and captured diagnostics.

+# Plugin market index generator
+
+English | [中文](README.zh.md)
+
+A reference generator for [plugin market index](../../.agents/notes/implemented/feature/2026-10-02-plugin-market-index-format.md) files. It reads a plain list of npm package names and Git repository URLs and writes one `index.json` that the DSH **Discover** page can show without further requests. It is a standalone Node program, not a Cordis application, and it never installs or runs the code of the packages it describes.
+
+## Usage
+
+Write a source list, one entry per line. Blank lines and lines starting with `#` are ignored.
+
+```text
+# npm packages: every non-deprecated bundle version is listed
+@scope/dsh-example
+dsh-another-plugin
+# Git repositories: release tags and the default branch are listed
+https://github.com/author/dsh-plugin
+https://gitlab.example.com/group/dsh-plugins
+```
+
+Run the generator from the repository:
+
+```sh
+pnpm --filter @deepseek-ai/dsh-plugin-market-generator start \
+  --input plugins.txt --output site/index.json --title "Example Market"
+```
+
+`--input` and `--output` are relative to the directory where you run pnpm. Publish the output directory over https, then add the `index.json` URL as an index source in Discover.
+
+| Option | Default | Meaning |
+|---|---|---|
+| `--input <file>` | required | Source list. |
+| `--output <file>` | required | Index file. Icons too large to inline are written to `icons/` next to it; generated icon files the index no longer uses are removed from there. |
+| `--title <text>` | required | Market title. |
+| `--description <text>` | none | Market description. |
+| `--cache <dir>` | `.plugin-market-cache` next to the input list | Result cache. It stays out of the output directory, which is published. |
+| `--registry <url>` | `https://registry.npmjs.org/` | npm registry. Any other registry is recorded in each npm version. |
+| `--inline-icon-bytes <n>` | `16384` | Largest icon embedded as a `data:` URL, at most 32768, the format's inline icon limit. |
+| `--concurrency <n>` | `4` | Sources read at the same time. |
+| `--timeout-ms <n>` | `60000` | Deadline for one request or Git command. |
+| `-h`, `--help` | | Print these options and the exit statuses. |
+
+The exit status is 0 when every source was read, 1 when a source could not be read, and 2 for invalid arguments or an invalid list. A list line that the index format would reject, such as an `http:` URL, a URL with credentials, a query, or a fragment, a URL with fewer than two path segments, or a tarball URL, is an invalid list. A source that cannot be read keeps its last successful result, so a temporary outage does not remove plugins from the index; the failure is still reported.
+
+## What gets listed
+
+Each package becomes one plugin with one or more versions. A version is listed only when its `package.json` declares `dsh.bundle` with `patch` set to a file path or a list of file paths.
+
+- **npm package**: every version in the registry document that is not deprecated, declares a bundle, and has a publish time. Versions come from the registry document alone; only the tarball of the highest listed version is downloaded, for its display fields. Its `package.json` must name the requested package and version.
+- **Git repository**: bundle packages are found on the default branch, in this order:
+  1. the root `package.json` declares `dsh.bundle`: the root package only;
+  2. `package.json` `workspaces` or `pnpm-workspace.yaml` `packages` match packages that declare `dsh.bundle`: those packages. Each glob segment is a literal name, a name with `*`, or `**`; negated globs are ignored, and a glob that matches nothing is reported;
+  3. otherwise, every package declaring `dsh.bundle` within three directory levels, outside `node_modules`, `test`, `tests`, `fixtures`, `example`, and `examples`.
+
+  Each package's versions come from release tags and the default branch. A `vX.Y.Z` or `X.Y.Z` tag applies to every package, and a `<name>@X.Y.Z` tag, such as `@scope/dsh-a@1.2.0`, to the package with that name; the tag version must be an exact SemVer version. A tag lists a package when the package's directory at the tagged commit holds a bundle manifest with the same name and the tag's version. The default branch commit lists each package's current version unless a tag already lists it. When several tags list one version, a `<name>@` tag wins over a unified tag, then the earlier commit wins. The publish time is the commit's committer time.
+
+`engines.dsh` is the manifest's `engines.dsh`, trimmed. Without one, it is the conjunction of the manifest's `@deepseek-ai/dsh` and `@deepseek-ai/dsh-*` `peerDependencies` ranges; a peer of exactly `workspace:*`, `workspace:^`, or `workspace:~` means the running DSH version and adds nothing, and identical ranges appear once. A `*` range admits every version, so a version whose ranges are all `*` lists no `engines.dsh`. A version is skipped with a warning when installation would refuse it on every DSH version: an empty range, a `workspace:` value in `engines.dsh` or any other `workspace:` peer, an invalid range, or ranges that no version satisfies together.
+
+Display fields come from the highest listed version and follow the rules DSH uses for installed plugins. `./locale/en.json` and `./locale/<language>.json` are resolved through the package `exports` map with the `import`, `node`, and `default` conditions, or literally without one, and every locale file must sit in the English file's directory; their `meta.title` and `meta.description` fall back to the manifest `name` and `description`. The icon is the manifest `icon`, a relative path, or else the exported `./icon`: SVG, PNG, JPEG, or WebP, at most 256 KiB, inside the package. `author` is the name part of the manifest `author` string, without its `<email>` and `(url)`, or the `name` of an author object. `homepage` is the manifest `homepage` as written when it is an absolute http(s) URL; nothing else, such as `repository`, stands in for a missing one. `repository` is the web page of the manifest `repository`, a shorthand such as `github:o/r` or a URL, through [hosted-git-info](https://github.com/npm/hosted-git-info) for hosts it knows, without any `#` committish; another http(s) URL loses a `git+` prefix, credentials, query, fragment, and `.git` suffix. Its `directory` is copied when the format accepts it. A repository with no http(s) page, or an unusable `directory`, is reported and omitted. Malformed locale files, invalid locale names, and rejected icons are reported as warnings. Translations without English text or a manifest fallback are dropped because the format requires English. Every entry is checked with [`dsh-plugin-market-index`](../../packages/util/plugin-market-index/README.md) before it is written.
+
+`metadata.keywords` is an optional array of strings for discovery. npm `package.json` `keywords` is the convention; index generators may supplement or adjust it. This reference generator copies the highest listed version's manifest `keywords` unchanged, including empty strings, duplicates, and an empty array. An absent field is omitted; a non-array value or an array containing any non-string produces a warning and omits the whole field without dropping the package.
+
+When several sources produce the same package name, the first one in the list wins.
+
+## Caching and repeated runs
+
+Each run reads the registry document of every npm source and the refs of every Git repository. Results are cached per immutable input: an npm plugin per registry, icon threshold, package, and set of listed versions; a Git repository per default branch commit and release tags; and each Git package per commit and directory. A Git run therefore fetches only the commits whose packages are not cached. Cache files are written atomically, and a cache file that is damaged or that the index format rejects is rebuilt. Output is deterministic: entries follow the list order, and the index and icon files are rewritten only when their contents change, so running the generator again without upstream changes leaves the output untouched.
+
+## Security
+
+The generator downloads and reads files only. npm tarballs are read in memory: a tarball and its unpacked files may not exceed 64 MiB each, the bytes must match the registry integrity hash, and only regular files outside `node_modules` are kept, without paths that leave the package. Git objects are fetched with depth 1 into a private temporary bare repository and read as blobs, so no working tree exists and no checkout filter, LFS download, or symbolic link takes effect; symbolic links and submodules count as absent. Git runs with hooks and the file-system monitor disabled, no submodules, only the https and ssh transports, and without inherited `GIT_*` variables except `GIT_SSH` and `GIT_SSH_COMMAND`. Your ssh program and `GIT_SSH_COMMAND` keep precedence; without either, ssh runs in batch mode, so it never waits for a prompt. Manifests, locale files, and workspace files over 1 MiB are refused. Private repositories use your Git credential configuration; an https URL can be routed to ssh with `url.<base>.insteadOf`.
+
+Index content is what the packages claim about themselves. Review the list you publish: a listed repository can use any package name.
+
+## Limits
+
+- A Git server must allow fetching a commit by its SHA, as GitHub, GitLab, and Gitea do. When a server refuses, the generator fetches the tags and the default branch by name, which fails if a ref moved after it was listed.
+- Registry tokens from `.npmrc` are not applied; only public or unauthenticated registries work.
+- Git never prompts for credentials. A repository that needs them must be readable through a credential helper or an ssh agent.

+# 插件市场索引生成器
+
+[English](README.md) | 中文
+
+[插件市场索引](../../.agents/notes/implemented/feature/2026-10-02-plugin-market-index-format.zh.md)文件的参考生成器。它读取一份由 npm 包名和 Git 仓库 URL 组成的纯文本列表，写出一个 `index.json`，DSH 的 **发现** 页面无需额外请求即可展示该文件。它是独立的 Node 程序，不是 Cordis 应用，也从不安装或运行其所描述包的代码。
+
+## 用法
+
+编写来源列表，每行一个条目。生成器忽略空行和以 `#` 开头的行。
+
+```text
+# npm packages: every non-deprecated bundle version is listed
+@scope/dsh-example
+dsh-another-plugin
+# Git repositories: release tags and the default branch are listed
+https://github.com/author/dsh-plugin
+https://gitlab.example.com/group/dsh-plugins
+```
+
+在仓库中运行生成器：
+
+```sh
+pnpm --filter @deepseek-ai/dsh-plugin-market-generator start \
+  --input plugins.txt --output site/index.json --title "Example Market"
+```
+
+`--input` 和 `--output` 相对于你运行 pnpm 的目录。通过 https 发布输出目录，然后在「发现」中把该 `index.json` 的 URL 添加为索引来源。
+
+| 选项 | 默认值 | 含义 |
+|---|---|---|
+| `--input <file>` | 必填 | 来源列表。 |
+| `--output <file>` | 必填 | 索引文件。过大而无法内联的图标写入其旁边的 `icons/`；索引不再使用的已生成图标文件会从该目录删除。 |
+| `--title <text>` | 必填 | 市场标题。 |
+| `--description <text>` | 无 | 市场描述。 |
+| `--cache <dir>` | 输入列表旁的 `.plugin-market-cache` | 结果缓存。它不在会被发布的输出目录中。 |
+| `--registry <url>` | `https://registry.npmjs.org/` | npm 注册表。使用其他注册表时，该注册表会记录在每个 npm 版本中。 |
+| `--inline-icon-bytes <n>` | `16384` | 以 `data:` URL 内嵌的图标的最大字节数，不超过格式的内联图标上限 32768。 |
+| `--concurrency <n>` | `4` | 同时读取的来源数。 |
+| `--timeout-ms <n>` | `60000` | 单个请求或 Git 命令的时限。 |
+| `-h`、`--help` | | 打印这些选项和退出状态。 |
+
+所有来源都读取成功时退出状态为 0，有来源无法读取时为 1，参数无效或列表无效时为 2。索引格式会拒绝的列表行属于无效列表，例如 `http:` URL、带凭据、查询或片段的 URL、路径段少于两个的 URL，以及 tarball URL。无法读取的来源保留其上一次成功的结果，因此临时故障不会把插件从索引中移除；生成器仍会报告该失败。
+
+## 列出的内容
+
+每个包成为一个插件，带有一个或多个版本。只有 `package.json` 声明了 `dsh.bundle`、且其 `patch` 是一个文件路径或文件路径列表的版本才会列出。
+
+- **npm 包**：注册表文档中未弃用、声明了组合包（bundle）且有发布时间的每个版本。版本只取自注册表文档；生成器只下载最高列出版本的 tarball，用于读取展示字段。该 tarball 的 `package.json` 必须与所请求的包名和版本一致。
+- **Git 仓库**：生成器按以下顺序在默认分支上查找组合包：
+  1. 根 `package.json` 声明了 `dsh.bundle`：仅使用根包；
+  2. `package.json` 的 `workspaces` 或 `pnpm-workspace.yaml` 的 `packages` 匹配到声明了 `dsh.bundle` 的包：使用这些包。每个 glob 段可以是字面名称、含 `*` 的名称或 `**`；生成器忽略否定 glob，并报告未匹配任何内容的 glob；
+  3. 否则，使用三层目录以内、位于 `node_modules`、`test`、`tests`、`fixtures`、`example` 和 `examples` 之外的所有声明了 `dsh.bundle` 的包。
+
+  每个包的版本来自发布标签（tag）和默认分支。`vX.Y.Z` 或 `X.Y.Z` 标签适用于所有包，`<name>@X.Y.Z` 标签（例如 `@scope/dsh-a@1.2.0`）适用于同名的包；标签中的版本必须是确切的 SemVer 版本。当包目录在打标签的提交中有一个组合包 manifest（元数据清单），且其名称相同、版本等于标签版本时，该标签列出这个包。默认分支的提交列出每个包的当前版本，除非某个标签已经列出该版本。多个标签列出同一版本时，`<name>@` 标签优先于统一标签，其次是较早的提交。发布时间是该提交的提交者时间。
+
+`engines.dsh` 取 manifest 的 `engines.dsh` 并去掉首尾空白。没有该字段时，它是 manifest 中 `@deepseek-ai/dsh` 和 `@deepseek-ai/dsh-*` 的 `peerDependencies` 范围的合取；恰为 `workspace:*`、`workspace:^` 或 `workspace:~` 的 peer 表示当前运行的 DSH 版本，不增加限制；相同的范围只出现一次。`*` 范围接受所有版本，因此范围全为 `*` 的版本不列出 `engines.dsh`。如果安装时在所有 DSH 版本上都会拒绝某个版本，该版本会被跳过并发出警告：范围为空、`engines.dsh` 中出现 `workspace:` 值或 peer 中出现其他 `workspace:` 范围、范围无效，或者没有任何版本能同时满足这些范围。
+
+展示字段来自最高的列出版本，并遵循 DSH 读取已安装插件时的规则。`./locale/en.json` 和 `./locale/<language>.json` 通过包的 `exports` 映射以 `import`、`node` 和 `default` 条件解析，没有该映射时按字面路径读取，并且每个 locale 文件都必须与英文文件位于同一目录；其 `meta.title` 和 `meta.description` 缺失时回退到 manifest 的 `name` 和 `description`。图标是 manifest 的 `icon`（相对路径），否则是导出的 `./icon`：格式为 SVG、PNG、JPEG 或 WebP，不超过 256 KiB，并位于包内。`author` 是 manifest `author` 字符串中去掉 `<email>` 和 `(url)` 后的名字部分，或 author 对象的 `name`。`homepage` 在 manifest 的 `homepage` 是绝对 http(s) URL 时按原样复制；缺少时不会用 `repository` 等其他字段代替。`repository` 是 manifest `repository`（如 `github:o/r` 这样的简写或 URL）对应的网页：已知主机通过 [hosted-git-info](https://github.com/npm/hosted-git-info) 转换，并去掉 `#` 后的 committish；其他 http(s) URL 去掉 `git+` 前缀、凭据、查询、片段和 `.git` 后缀。格式接受时复制其 `directory`。没有 http(s) 网页的仓库或不可用的 `directory` 会被报告并省略。格式错误的 locale 文件、无效的 locale 名称和被拒绝的图标会作为警告报告。由于该格式要求英文，没有英文文本也没有 manifest 回退值的翻译会被丢弃。每个条目在写出前都经过 [`dsh-plugin-market-index`](../../packages/util/plugin-market-index/README.zh.md) 校验。
+
+`metadata.keywords` 是用于发现插件的可选字符串数组。按约定使用 npm `package.json` 的 `keywords`；索引生成器可以补充或调整它。本参考生成器原样复制最高列出版本 manifest 的 `keywords`，包括空字符串、重复值和空数组。字段缺省时省略；如果值不是数组，或数组包含任何非字符串成员，则发出警告并省略整个字段，但保留该包。
+
+多个来源产生相同包名时，列表中靠前的来源生效。
+
+## 缓存与重复运行
+
+每次运行时，生成器读取每个 npm 来源的注册表文档和每个 Git 仓库的引用（ref）。结果按不可变的输入缓存：npm 插件按注册表、图标阈值、包和列出版本的集合缓存；Git 仓库按默认分支提交和发布标签缓存；每个 Git 包按提交和目录缓存。因此 Git 运行只拉取其包尚未缓存的提交。生成器以原子方式写入缓存文件，并重建损坏的或索引格式会拒绝的缓存文件。输出是确定性的：条目按列表顺序排列，索引文件和图标文件只在内容变化时才重写，因此上游没有变化时再次运行生成器不会改动输出。
+
+## 安全
+
+生成器只下载和读取文件。npm tarball 在内存中读取：tarball 及其解包后的文件各自不能超过 64 MiB，字节必须与注册表的完整性哈希一致，并且只保留 `node_modules` 之外的普通文件，不接受离开包目录的路径。Git 对象以深度 1 拉取到一个私有的临时裸仓库，并作为 blob 读取，因此不存在工作树，检出过滤器、LFS 下载和符号链接都不会生效；符号链接和子模块视为不存在。Git 运行时禁用钩子和文件系统监视器、不处理子模块、只允许 https 和 ssh 传输协议，并且不继承除 `GIT_SSH` 和 `GIT_SSH_COMMAND` 之外的 `GIT_*` 变量。你配置的 ssh 程序和 `GIT_SSH_COMMAND` 优先；两者都没有时，ssh 以批处理模式运行，因此不会等待输入。超过 1 MiB 的 manifest、语言文件和工作区文件会被拒绝。私有仓库使用你的 Git 凭据配置；可以用 `url.<base>.insteadOf` 把 https URL 改为通过 ssh 访问。
+
+索引内容是各个包对自身的声明。请审查你发布的列表：列出的仓库可以使用任意包名。
+
+## 限制
+
+- Git 服务器必须允许按 SHA 拉取提交，GitHub、GitLab 和 Gitea 都允许。服务器拒绝时，生成器按名称拉取标签和默认分支；如果某个引用在列出之后移动了，这一步会失败。
+- 生成器不使用 `.npmrc` 中的注册表令牌；只支持公开或无需认证的注册表。
+- Git 从不提示输入凭据。需要凭据的仓库必须能通过凭据助手或 ssh agent 读取。

 `ChangeResult.changed` reports a disk edit independently of `application`: `applied`, `restart-required`, `overridden` or `failed`. Optional `error` carries a localizable code and external diagnostic. `packageResult` records the pnpm exit code, bounded output, truncation flag and complete diagnostic log path, plus `timedOut` when the manager terminated a run that stopped printing. A terminated run is classified `timeout` whatever exit status the signal left behind, so installation and removal report failure instead of success and no further registry is asked. `pendingBuilds` lists undecided packages across the profile; `approvedBuilds` records the names granted permission by this operation; `registries` lists the registries an installation asked, in order; `bundle` and `version` name the package a finished installation added and its manifest version; `failedAt` says whether the last failed run could not reach the registry it asked or the host a git or tarball spec is fetched from.
 
+## Market records
+
+[Plugin Market](../../packages/boot/plugin-market/README.md) reads index format 1, validated by [`dsh-plugin-market-index`](../../packages/util/plugin-market-index/README.md).
+
+`MarketIndexSummary` carries one configured index URL with the `title` and `description` of its last successful read and, when the last read failed, its `error`.
+
+`MarketQuery` selects one page of an index: fuzzy `text`, a `category`, `labels` that must all be present, a `MarketSort`, `offset`, `limit` up to 100, `refresh` to fetch again instead of using a cached document, and `fetchedAt` to continue the pages of one document. `MarketSearchResult` carries the index URL, `title`, optional `description`, market `metadata`, the document's `fetchedAt`, the page's `entries`, the `total` number of matches, and the `nextOffset`. Each `MarketListingEntry` adds `defaultVersion`, the version installed by default, and `installation`, the profile's status for the package name; each of its `versions` adds `install`, the exact spec and optional first registry for `installBundle`, and `compatibility`, the evaluation of its `engines.dsh` including a version exemption.

+---
+
+# Plugin compatibility reads `engines.dsh` first
+
+English | [中文](guide.zh.md)
+
+## Change
+
+In v0.2.1-alpha.3, installation and profile startup judged a plugin or bundle only by its `peerDependencies` on `@deepseek-ai/dsh` and `@deepseek-ai/dsh-*`, and ignored `engines.dsh`. In the next release, an own `engines.dsh` range decides alone and those peers are ignored; the peer rule applies only when `engines.dsh` is absent. `workspace:` values are valid only in peers; in `engines.dsh` they are incompatible. A non-object `engines` or a non-string `engines.dsh` makes the manifest unreadable for compatibility, which refuses the package. Plugin authors whose package declares `engines.dsh`, or declares `engines` as something other than an object, are affected.
+
+The `incompatible-version` refusal record that the plugin manager returns to clients, `IncompatiblePlugin`, and the app-boot `PluginCompatibility` result rename `peers` to `requirements`. Keys are `engines.dsh` for the engines rule or the peer package name for the fallback. Code that reads these records is affected.
+
+## Migration
+
+1. If your package declares `engines.dsh`, make that range cover every DSH release the package supports, because DSH peer ranges no longer widen or narrow it. Remove `engines.dsh` to keep peer-based checking.
+2. Replace `workspace:` values in `engines.dsh` with a semantic version range.
+3. Read `requirements` instead of `peers` from `IncompatiblePlugin` and `PluginCompatibility`.
+4. Confirm by installing the package with `dsh plugin --profile <profile> add <package@version>` or the plugin manager: a mismatch names `engines.dsh` or the peer package in the refusal.

+# 插件兼容性先读 `engines.dsh`
+
+[English](guide.md) | 中文
+
+## 变更
+
+在 v0.2.1-alpha.3 中，安装和 profile 启动只依据插件或组合包在 `peerDependencies` 中对 `@deepseek-ai/dsh` 和 `@deepseek-ai/dsh-*` 的声明判定兼容性，忽略 `engines.dsh`。下一版本中，包自身的 `engines.dsh` 范围单独决定结果，并忽略这些 peer；只有缺少 `engines.dsh` 时才使用 peer 规则。`workspace:` 值只在 peer 中有效；出现在 `engines.dsh` 中时视为不兼容。`engines` 不是对象或 `engines.dsh` 不是字符串时，兼容性检查无法读取清单，该包会被拒绝。受影响的是声明了 `engines.dsh`，或把 `engines` 声明为非对象值的插件作者。
+
+插件管理器返回给客户端的 `incompatible-version` 拒绝记录 `IncompatiblePlugin`，以及 app-boot 的 `PluginCompatibility` 结果，将 `peers` 重命名为 `requirements`。按 engines 规则判定时键为 `engines.dsh`，回退到 peer 规则时键为 peer 包名。读取这些记录的代码受影响。
+
+## 迁移
+
+1. 如果包声明了 `engines.dsh`，让该范围覆盖包支持的所有 DSH 版本，因为 DSH peer 范围不再放宽或收窄它。删除 `engines.dsh` 可保留基于 peer 的检查。
+2. 将 `engines.dsh` 中的 `workspace:` 值替换为语义化版本范围。
+3. 从 `IncompatiblePlugin` 和 `PluginCompatibility` 读取 `requirements`，不再读取 `peers`。
+4. 用 `dsh plugin --profile <profile> add <package@version>` 或插件管理器安装该包确认迁移：不匹配时，拒绝信息会列出 `engines.dsh` 或对应 peer 包。

+# Plugin markets
+
+English | [中文](plugin-market.zh.md)
+
+## Summary
+
+A plugin market is one JSON index file that lists installable DSH bundles with their titles, icons, authors, and versions. Turn on the experimental **Custom plugin markets** bundle to browse markets in a **Discover** tab on the Plugins page and install a listed version after a confirmation. To publish a market, write or generate an index file and serve it, together with its icon files, from any static host.

+<a id="turn-on"></a>
+## Turn on Discover
+
+Open **Plugins**, select **More** beside **Experimental plugins**, find **Custom plugin markets**, and switch it on. A **Discover** tab appears next to **Installed**, and Creator mode gains the read-only `plugin_market` tool. Switching the bundle off removes both again.
+
+DSH ships no index source. Select **Discover**, choose **Add index source**, and enter the URL of an index file. A URL must use `http:` or `https:` and must not contain a user name, password, or `#` fragment. Anyone on the network path can change an `http:` index, including the install specs it lists, so use `https:` for a market reached over a network you do not control. Each source belongs to the current profile.
+
+<a id="browse-and-install"></a>
+## Browse and install
+
+The market menu at the left of the toolbar switches between sources and opens **Manage index sources…**, where each source shows its last error. Search matches names, authors, keywords, and titles, descriptions, categories, and labels in every language, and tolerates typos; results come in best-match order until you choose another. The **Labels** menu, category pills, and **Sort** menu use the categories, labels, and sort keys that the market declares, and **Publish date** sorts by each plugin's latest version.
+
+Each card shows the plugin's recommended version: the highest version compatible with the running DSH that is not a prerelease, or the highest compatible prerelease when the plugin lists no version without a prerelease tag. **Install** opens a confirmation with that version's source: the npm package and registry, or the Git repository, commit, and directory. Confirming starts the normal plugin installation, including its compatibility and registry checks; nothing is installed without that confirmation.
+
+Select a card to open its page. The **Versions** list shows every listed version with its compatibility and offers **Install** for any version DSH accepts, including older releases and prereleases. A card that shows **Installed**, **Update available**, or **Provided by DSH** opens the installed bundle instead.
+
+Markets are third-party content. A market chooses each plugin's title, description, icon, author, and source; DSH checks the file format but not those claims. Add only sources you trust, and check the source in the confirmation before installing.
+
+<a id="publish-an-index"></a>
+## Publish an index
+
+An index is a UTF-8 JSON file, at most 128 MiB by default, served with a 2xx status and without redirects. Put it on any static host, for example GitLab Pages, GitHub Pages, or an object store behind https.
+
+Icons can be inline or separate files. An inline icon is a base64 `data:` URL in the index; it needs no extra request but makes the index larger. A separate icon is a URL. A relative icon resolves against the index URL, the way an image in a web page resolves against the page: for an index at `https://market.example/dsh/index.json`, `"icon": "icons/foo.svg"` loads `https://market.example/dsh/icons/foo.svg`. Publishing the index and an `icons/` directory side by side therefore works on any host without editing the file. An absolute icon URL on another origin (scheme, host, and port) must use `https:`.
+
+This is a minimal index with one npm plugin and one plugin from a Git monorepo:
+
+```json
+{
+  "format": 1,
+  "title": { "en": "Team plugins", "zh": "团队插件" },
+  "plugins": [
+    {
+      "name": "dsh-plugin-foo",
+      "title": "Foo",
+      "description": "Adds the foo tool",
+      "icon": "icons/foo.svg",
+      "author": "Jane Doe",
+      "homepage": "https://github.com/jane/dsh-plugin-foo#readme",
+      "repository": { "url": "https://github.com/jane/dsh-plugin-foo" },
+      "versions": [
+        { "version": "1.1.0", "publishTimestamp": 1790476800, "source": { "type": "npm" }, "engines": { "dsh": ">=0.2.0-rc.2" } },
+        { "version": "1.0.0", "publishTimestamp": 1788000000, "source": { "type": "npm" } }
+      ]
+    },
+    {
+      "name": "@team/dsh-bar",
+      "versions": [
+        {
+          "version": "0.3.0",
+          "publishTimestamp": 1789000000,
+          "source": {
+            "type": "git",
+            "url": "https://gitlab.example.com/team/dsh-plugins",
+            "commit": "3f9c2e1d8a4b6c0e7f1a2b3c4d5e6f708192a3b4",
+            "path": "packages/bar"
+          }
+        }
+      ]
+    }
+  ]
+}
+```
+
+DSH rejects the whole index when any rule below is violated and shows the reason, with the JSON path of the offending value, under the source in **Manage index sources…**.
+
+<a id="generate-an-index"></a>
+## Generate an index with the reference generator
+
+The repository includes a [reference generator](../../../apps/plugin-market-generator/README.md) that builds an index from a plain list. Write one npm package name or https Git repository URL per line; blank lines and lines starting with `#` are ignored:
+
+```text
+@team/dsh-foo
+https://gitlab.example.com/team/dsh-plugins
+```
+
+Run it from a DSH checkout:
+
+```sh
+pnpm --filter @deepseek-ai/dsh-plugin-market-generator start --input plugins.txt --output site/index.json --title "Team plugins"
+```
+
+For an npm package, the index lists every version that is not deprecated and declares `dsh.bundle`. For a Git repository, it finds the bundle packages on the default branch and lists their versions at `vX.Y.Z`, `X.Y.Z`, and `<name>@X.Y.Z` tags, plus each package's version on the default branch. Titles, descriptions, icons, authors, and homepages come from each plugin's highest version. Paths are relative to the directory where you run pnpm.
+
+The generator only downloads and reads files; it never installs packages or runs their code. It keeps a cache in `.plugin-market-cache` next to the list, so a repeated run downloads only new versions and commits. Publish the output directory, `index.json` together with its `icons/` directory, as described above.
+
+<a id="index-format"></a>
+## Index format reference
+
+Text fields marked `LocalizedText` are a string or an object of strings keyed by lowercase language ids, such as `{ "en": "Foo", "zh": "甲" }`; an object must contain `en`. Members DSH does not know are ignored.
+
+| Index field | Required | Meaning |
+|---|---|---|
+| `format` | yes | `1`. |
+| `title`, `description` | `title` only | Market name and description, `LocalizedText`. |
+| `metadata.categories`, `metadata.labels` | no | Objects mapping an id to `{ "title": LocalizedText }`. |
+| `metadata.sortKeys` | no | Object mapping an id to `{ "title": LocalizedText, "order": "asc" \| "desc" }`; `order` is the initial direction. |
+| `plugins` | yes | Plugins in the market's default order. |
+
+| Plugin field | Required | Meaning |
+|---|---|---|
+| `name` | yes | npm package name, unique in the index. |
+| `title`, `description` | no | `LocalizedText`; the card shows `name` without a title. |
+| `icon` | no | Inline `data:` URL (SVG, PNG, JPEG, or WebP, at most 32 KiB) or URL, as described above. |
+| `author` | no | Display text. |
+| `homepage` | no | Absolute `https:` or `http:` URL of a page about the plugin; the plugin page links it. |
+| `repository` | no | `{ "url": string, "directory"?: string }`: the source repository's web page, and the package directory inside it. The plugin page links it as **Source code**. |
+| `metadata.category` | no | One declared category id. |
+| `metadata.labels` | no | Declared label ids. |
+| `metadata.sortKeys` | no | Object mapping declared sort-key ids to numbers, such as downloads or ratings. |
+| `versions` | yes | At least one version, in any order. |
+
+| Version field | Required | Meaning |
+|---|---|---|
+| `version` | yes | Exact SemVer version, unique within the plugin. |
+| `publishTimestamp` | yes | Publish time in Unix seconds. |
+| `source` | yes | `{ "type": "npm", "registry"?: url }`, or `{ "type": "git", "url": https-url, "commit": 40-hex-sha, "path"?: directory }`. |
+| `engines.dsh` | no | SemVer range of DSH versions this version runs on; absent means any. |
+
+DSH installs an npm version as `name@version`, asking `registry` first when present, and a Git version as `git+<url>.git#<commit>` with `&path:/<path>` for a package in a subdirectory. `engines.dsh` should match the package's own `engines.dsh`, which DSH checks again at installation; a package without one is checked against its `@deepseek-ai/dsh*` peer dependencies instead. The [format note](../../../.agents/notes/implemented/feature/2026-10-02-plugin-market-index-format.md) defines every rule.

+# 插件市场
+
+[English](plugin-market.md) | 中文
+
+## 概述
+
+插件市场是一个 JSON 索引文件，列出可安装的 DSH 组合包（bundle）及其标题、图标、作者和版本。打开实验性的**自定义插件市场**组合包后，可以在插件页的**发现**标签页中浏览市场，并在确认后安装列出的版本。要发布市场，编写或生成一个索引文件，并把它和图标文件一起放到任意静态主机上。
+
+## 目录
+
+- [打开「发现」](#turn-on)
+- [浏览和安装](#browse-and-install)
+- [发布索引](#publish-an-index)
+- [用参考生成器生成索引](#generate-an-index)
+- [索引格式参考](#index-format)
+- [延伸阅读](#further-exploration)
+
+<a id="turn-on"></a>
+## 打开「发现」
+
+打开**插件**，点击**实验性插件**旁的**更多**，找到**自定义插件市场**并打开开关。**已安装**旁边会出现**发现**标签页，Creator 模式也会获得只读的 `plugin_market` 工具。关闭该组合包会再次移除这两者。
+
+DSH 不内置任何索引源。选择**发现**，点击**添加索引源**，输入一个索引文件的 URL。URL 必须使用 `http:` 或 `https:`，并且不能包含用户名、密码或 `#` 片段。网络路径上的任何人都能修改 `http:` 索引，包括其中列出的安装 spec，因此经由不受你控制的网络访问的市场应使用 `https:`。每个索引源属于当前 profile。
+
+<a id="browse-and-install"></a>
+## 浏览和安装
+
+工具栏左侧的市场菜单用于切换索引源，并可打开**管理索引源…**，其中每个索引源显示它最近一次的错误。搜索匹配名称、作者、关键词，以及所有语言的标题、描述、分类和标签，并容忍拼写错误；在你选择其他排序之前，结果按最佳匹配排序。**标签**菜单、分类按钮和**排序**菜单使用市场声明的分类、标签和排序键，**发布时间**按每个插件最新版本的时间排序。
+
+每张卡片显示插件的推荐版本：与当前运行的 DSH 兼容、且不是预发布版本的最高版本；插件没有列出任何非预发布版本时，则是兼容的最高预发布版本。**安装**会打开确认框，显示该版本的来源：npm 包和注册表，或 Git 仓库、提交和目录。确认后开始常规的插件安装，包括其中的兼容性检查和注册表检查；未经确认不会安装任何内容。
+
+选择卡片会打开插件页面。**版本**列表显示列出的每个版本及其兼容性，并为 DSH 接受的任何版本提供**安装**，包括旧版本和预发布版本。显示**已安装**、**有新版本**或**随 DSH 提供**的卡片会改为打开已安装的组合包。
+
+市场是第三方内容。每个插件的标题、描述、图标、作者和来源都由市场决定；DSH 检查文件格式，但不验证这些声明。只添加你信任的索引源，并在安装前核对确认框中的来源。
+
+<a id="publish-an-index"></a>
+## 发布索引
+
+索引是 UTF-8 编码的 JSON 文件，默认不超过 128 MiB，以 2xx 状态码返回且不经过重定向。把它放到任意静态主机上即可，例如 GitLab Pages、GitHub Pages，或通过 https 访问的对象存储。
+
+图标可以内联，也可以是单独的文件。内联图标是索引中的 base64 `data:` URL；它不需要额外请求，但会使索引变大。单独的图标是一个 URL。相对图标相对于索引 URL 解析，与网页中的图片相对于页面解析的方式相同：对于位于 `https://market.example/dsh/index.json` 的索引，`"icon": "icons/foo.svg"` 会加载 `https://market.example/dsh/icons/foo.svg`。因此把索引和 `icons/` 目录并排发布，在任何主机上都能使用，无需修改文件。指向其他源（协议、主机和端口）的绝对图标 URL 必须使用 `https:`。
+
+下面是一个最小的索引，包含一个 npm 插件和一个来自 Git monorepo 的插件：
+
+```json
+{
+  "format": 1,
+  "title": { "en": "Team plugins", "zh": "团队插件" },
+  "plugins": [
+    {
+      "name": "dsh-plugin-foo",
+      "title": "Foo",
+      "description": "Adds the foo tool",
+      "icon": "icons/foo.svg",
+      "author": "Jane Doe",
+      "homepage": "https://github.com/jane/dsh-plugin-foo#readme",
+      "repository": { "url": "https://github.com/jane/dsh-plugin-foo" },
+      "versions": [
+        { "version": "1.1.0", "publishTimestamp": 1790476800, "source": { "type": "npm" }, "engines": { "dsh": ">=0.2.0-rc.2" } },
+        { "version": "1.0.0", "publishTimestamp": 1788000000, "source": { "type": "npm" } }
+      ]
+    },
+    {
+      "name": "@team/dsh-bar",
+      "versions": [
+        {
+          "version": "0.3.0",
+          "publishTimestamp": 1789000000,
+          "source": {
+            "type": "git",
+            "url": "https://gitlab.example.com/team/dsh-plugins",
+            "commit": "3f9c2e1d8a4b6c0e7f1a2b3c4d5e6f708192a3b4",
+            "path": "packages/bar"
+          }
+        }
+      ]
+    }
+  ]
+}
+```
+
+违反下列任何一条规则时，DSH 会拒绝整个索引，并在**管理索引源…**中该索引源下方显示原因及违规值的 JSON 路径。
+
+<a id="generate-an-index"></a>
+## 用参考生成器生成索引
+
+仓库包含一个[参考生成器](../../../apps/plugin-market-generator/README.zh.md)，可以从一份纯文本列表构建索引。每行写一个 npm 包名或 https Git 仓库 URL；空行和以 `#` 开头的行会被忽略：
+
+```text
+@team/dsh-foo
+https://gitlab.example.com/team/dsh-plugins
+```
+
+在 DSH 代码仓库中运行它：
+
+```sh
+pnpm --filter @deepseek-ai/dsh-plugin-market-generator start --input plugins.txt --output site/index.json --title "Team plugins"
+```
+
+对于 npm 包，索引列出所有未弃用且声明了 `dsh.bundle` 的版本。对于 Git 仓库，生成器在默认分支上查找组合包，列出它们在 `vX.Y.Z`、`X.Y.Z` 和 `<name>@X.Y.Z` 标签处的版本，以及每个包在默认分支上的版本。标题、描述、图标、作者和主页取自每个插件的最高版本。路径相对于你运行 pnpm 的目录。
+
+生成器只下载和读取文件，从不安装包或运行其代码。它在列表旁的 `.plugin-market-cache` 中保存缓存，因此再次运行时只下载新的版本和提交。按上文所述发布输出目录，即 `index.json` 及其 `icons/` 目录。
+
+<a id="index-format"></a>
+## 索引格式参考
+
+标为 `LocalizedText` 的文本字段是字符串，或以小写语言 id 为键的字符串对象，例如 `{ "en": "Foo", "zh": "甲" }`；对象必须包含 `en`。DSH 不认识的成员会被忽略。
+
+| 索引字段 | 必填 | 含义 |
+|---|---|---|
+| `format` | 是 | `1`。 |
+| `title`、`description` | 仅 `title` | 市场名称和描述，类型为 `LocalizedText`。 |
+| `metadata.categories`、`metadata.labels` | 否 | 将 id 映射为 `{ "title": LocalizedText }` 的对象。 |
+| `metadata.sortKeys` | 否 | 将 id 映射为 `{ "title": LocalizedText, "order": "asc" \| "desc" }` 的对象；`order` 是初始方向。 |
+| `plugins` | 是 | 按市场默认顺序排列的插件。 |
+
+| 插件字段 | 必填 | 含义 |
+|---|---|---|
+| `name` | 是 | npm 包名，在索引内唯一。 |
+| `title`、`description` | 否 | `LocalizedText`；没有标题时卡片显示 `name`。 |
+| `icon` | 否 | 内联 `data:` URL（SVG、PNG、JPEG 或 WebP，不超过 32 KiB）或 URL，见上文。 |
+| `author` | 否 | 显示文本。 |
+| `homepage` | 否 | 介绍该插件的页面的绝对 `https:` 或 `http:` URL；插件页面会链接到它。 |
+| `repository` | 否 | `{ "url": string, "directory"?: string }`：源代码仓库的网页，以及包在其中的目录。插件页面以**源代码**链接到它。 |
+| `metadata.category` | 否 | 一个已声明的分类 id。 |
+| `metadata.labels` | 否 | 已声明的标签 id。 |
+| `metadata.sortKeys` | 否 | 将已声明的排序键 id 映射为数值的对象，例如下载量或评分。 |
+| `versions` | 是 | 至少一个版本，顺序不限。 |
+
+| 版本字段 | 必填 | 含义 |
+|---|---|---|
+| `version` | 是 | 精确的 SemVer 版本，在插件内唯一。 |
+| `publishTimestamp` | 是 | 发布时间，Unix 秒。 |
+| `source` | 是 | `{ "type": "npm", "registry"?: url }`，或 `{ "type": "git", "url": https-url, "commit": 40 位十六进制 SHA, "path"?: 目录 }`。 |
+| `engines.dsh` | 否 | 该版本可运行的 DSH 版本的 SemVer 范围；缺省表示任意版本。 |
+
+DSH 将 npm 版本安装为 `name@version`，存在 `registry` 时先询问它；将 Git 版本安装为 `git+<url>.git#<commit>`，包位于子目录时追加 `&path:/<path>`。`engines.dsh` 应与包自身的 `engines.dsh` 一致，DSH 会在安装时再次检查；没有该字段的包改为按其 `@deepseek-ai/dsh*` peer 依赖检查。[格式说明](../../../.agents/notes/implemented/feature/2026-10-02-plugin-market-index-format.zh.md)定义了全部规则。

 A profile is how one dsh installation ships different app surfaces: `web`, `headless`, `acp`, `sdk`, and `sdk-minimal` start distinct compositions from the same launcher. A profile lives at `$DSH_HOME/profiles/<name>` and combines installable bundles with its own `cordis.patch.yml`. A bundle's `dsh.bundle.patch` names one patch file or an ordered list of files; `bundlePatchFiles` validates the declaration and `bundlePatchPaths` resolves it to absolute paths; the layer concatenates their patch lists in that order. The YAML composition enables or disables HMR. The shipped `web` template uses live reload, while the other shipped templates apply patches only at startup. `sdk-minimal` names only its standalone bundle; the other templates retain base-plus-mode stacks. `dsh --profile <name> --from-default-profile <template>` creates or replaces a custom profile at a non-shipped name from one shipped template, while `dsh plugin` initializes a base-backed profile and manages its installed bundles. Bundle resolution, manifest, and patch-loading failures skip that bundle without changing its selection; the loaded profile lists each skip in `skippedBundles`, and the launcher prints them once per start with `reportSkippedBundles`. Remaining bundles keep their order; profile and user-patch errors still fail startup. Skipping a bundle does not guarantee that the remaining composition can provide the required services. Application-owned npm projects, such as Electron's reserved Desktop profile, use `loadProfileDirectory` to load an already initialized directory without exposing it through CLI profile lookup.
 
-Before a profile imports a plugin, DSH checks its `peerDependencies` on `@deepseek-ai/dsh` and `@deepseek-ai/dsh-*` against the single runtime version returned by `getDshRuntimeVersion()`. Every declared range must match; prereleases participate in range matching. Source-workspace `workspace:^`, `workspace:~`, and `workspace:*` refer to that same runtime. Missing DSH peers impose no constraint; invalid ranges are incompatible. These checks use peer declarations, not `engines.dsh`, and are not a sandbox against malicious package code.
+Before a profile imports a plugin, DSH checks its declared DSH requirement against the single runtime version returned by `getDshRuntimeVersion()`. When the manifest declares `engines.dsh`, that range alone decides and `peerDependencies` are ignored. Otherwise every `peerDependencies` range on `@deepseek-ai/dsh` and `@deepseek-ai/dsh-*` must match, and source-workspace `workspace:^`, `workspace:~`, and `workspace:*` peers refer to that same runtime. Prereleases participate in range matching. A manifest with neither declaration imposes no constraint; empty or invalid ranges, including a `workspace:` value in `engines.dsh`, are incompatible. A non-object `engines` or a non-string `engines.dsh` is a malformed manifest. A refusal names the unmet requirements, keyed `engines.dsh` or by peer package name. These checks are not a sandbox against malicious package code.
 
-Admission happens only at composition boundaries DSH owns, and a denied row is denied in the launcher's own copy of the composition: no profile patch layer, dependency manifest, or bundle list changes. `prepareProfilePatches` composes over the launcher's empty profile root and runs while the root Include is mounted and on every profile recomposition, so a denied plugin never imports its module. `prepareProfileEntries` does the same for a preset's rows. A denied ordinary row becomes a detached `disabled: true` row; a native group stays mounted and its denied children do not load; a native Include that reaches a denied plugin is omitted whole, because its file is never rewritten. A row denied by policy keeps its configured `disabled` value in the profile, and every refusal is reported with the package, versions, and risk. A bundle is not a row, so `loadProfileDirectory` checks each bundle's own DSH peers when it loads the profile's bundle layers, at startup and on every recomposition; an incompatible bundle without an exemption is skipped like an unreadable one and listed in `skippedBundles`. These boundaries do not cover plugins another embedder mounts through its own `ctx.plugin` call. Two edits made directly to files during a session are judged only at the next recomposition or startup: a running plugin's own `package.json` peer declaration, and an entry-list file the Loader reads itself, such as the launcher's root config or a nested `cordis:include` file. `--dump-config` reports the configured composition, so a denied plugin row still appears there while a denied bundle contributes no rows, and `--dump-config-schema` imports each composed module to read its schema; run it only against a profile whose plugins you already trust.

 Exact-version exemptions live in the profile's own `compatibility.json`, not in its `package.json`, so an exemption write never touches the dependency manifest, the bundle list, or Cordis patch files. It maps exact `package-name@version` keys to lists of exact DSH runtime versions; neither a plugin upgrade nor a DSH upgrade inherits permission. A missing file means no exemptions. A malformed one never stops the profile from starting: records the reader accepts still apply, each rejected record is reported on stderr beside the plugin denials, and the file is then treated as read-only, so a grant or revocation refuses and asks the user to repair it by hand instead of overwriting their content. [Plugin Manager](../plugin-manager/README.md#version-compatibility-and-exemptions) owns the grant, revocation, and risk confirmation each change requires.

 profile 是同一套 dsh 安装提供不同应用界面的方式：`web`、`headless`、`acp`、`sdk` 与 `sdk-minimal` 从同一 launcher 启动不同组合。profile 位于 `$DSH_HOME/profiles/<name>`，由可安装组合包和自身 `cordis.patch.yml` 组成。组合包的 `dsh.bundle.patch` 指定一个 patch 文件或一个有序的文件列表；`bundlePatchFiles` 校验该声明，`bundlePatchPaths` 把它解析为绝对路径；该层按此顺序拼接各文件的 patch 列表。YAML 组合决定是否启用 HMR。随产品交付的 `web` 模板实时重载，其他随附模板只在启动时应用 patch。`sdk-minimal` 只列出自身的独立组合包，其他模板保留 base 加模式的组合包栈。`dsh --profile <name> --from-default-profile <template>` 从一个随附模板，在非内置名称处创建或替换自定义 profile；`dsh plugin` 则初始化以 base 为基础的 profile，并管理其中安装的组合包。组合包解析、manifest 读取或 patch 加载失败时会跳过该组合包，不改变其选择状态；加载结果在 `skippedBundles` 中列出每个被跳过的组合包，启动器每次启动时通过 `reportSkippedBundles` 输出一次。其余组合包保持原顺序；profile 和用户 patch 错误仍会导致启动失败。跳过组合包不保证剩余组合能够提供所需服务。由应用持有的 npm 项目（例如 Electron 保留的 Desktop profile）通过 `loadProfileDirectory` 加载已经初始化的目录，而不会将它暴露给 CLI profile 查找。
 
-profile 导入插件前，DSH 会检查其 `peerDependencies` 中对 `@deepseek-ai/dsh` 和 `@deepseek-ai/dsh-*` 的依赖，与 `getDshRuntimeVersion()` 返回的唯一运行时版本比较。每个声明的版本范围都必须匹配；预发布版本参与范围匹配。源码工作区的 `workspace:^`、`workspace:~` 和 `workspace:*` 指向同一个运行时。未声明 DSH peer 时不施加版本约束；无效范围视为不兼容。这些检查使用 peer 声明，而不是 `engines.dsh`，也不是防范恶意包代码的沙箱。
+profile 导入插件前，DSH 会将其声明的 DSH 版本要求与 `getDshRuntimeVersion()` 返回的唯一运行时版本比较。清单声明了 `engines.dsh` 时，只由该范围决定，忽略 `peerDependencies`。否则 `peerDependencies` 中对 `@deepseek-ai/dsh` 和 `@deepseek-ai/dsh-*` 的每个范围都必须匹配，源码工作区的 `workspace:^`、`workspace:~` 和 `workspace:*` peer 指向同一个运行时。预发布版本参与范围匹配。两者都未声明时不施加版本约束；空范围或无效范围视为不兼容，`engines.dsh` 中的 `workspace:` 值也属于无效范围。`engines` 不是对象或 `engines.dsh` 不是字符串时，清单视为格式错误。拒绝结果会列出未满足的要求，键为 `engines.dsh` 或 peer 包名。这些检查不是防范恶意包代码的沙箱。
 
-检查只发生在 DSH 自己持有的组合入口，改写的是启动器自己的那份组合：profile 的 patch 层、依赖清单与组合包列表都不会改变。`prepareProfilePatches` 在启动器的空 profile 根之上组合，并在挂载根 Include 时以及每次 profile 重新组合时执行，因此被拒绝的插件永远不会导入其模块；`prepareProfileEntries` 对 preset 行做同样的事。被拒绝的普通行会变成游离的 `disabled: true` 行；原生 group 保持挂载，其被拒绝的子行不会加载；若某个原生 Include 会到达被拒绝的插件，则整体省略该 Include，因为它的文件不会被改写。被策略拒绝的行在 profile 中保留其配置的 `disabled` 值，每次拒绝都会报告包名、版本与风险。组合包本身不是行，因此 `loadProfileDirectory` 在启动和每次重新组合加载 profile 的组合包层时，检查每个组合包自己声明的 DSH peer；没有豁免的不兼容组合包会像无法读取的组合包一样被跳过，并列入 `skippedBundles`。这些入口不覆盖其他嵌入方通过自己的 `ctx.plugin` 调用挂载的插件。会话中直接改文件的两类编辑只在下一次重新组合或启动时才被判定：正在运行的插件自己的 `package.json` peer 声明，以及 Loader 自己读取的入口清单文件（如启动器的根配置或嵌套的 `cordis:include` 文件）。`--dump-config` 报告的是配置出的组合，因此被拒绝的插件行仍会出现在其中，而被拒绝的组合包不提供任何行；`--dump-config-schema` 会导入每个组合模块以读取其 schema，请只对已经信任其插件的 profile 运行。

 精确版本豁免保存在 profile 自己的 `compatibility.json` 中，而不是 `package.json`，因此写豁免不会触及依赖清单、组合包列表或 Cordis patch 文件。它把精确的 `package-name@version` 键映射到精确 DSH 运行时版本列表；插件升级和 DSH 升级都不继承授权。文件缺失表示没有豁免。文件损坏绝不会阻止 profile 启动：读取器接受的记录仍然生效，每条被拒绝的记录会与插件拒绝信息一起输出到 stderr，此后该文件被视为只读，因此授予或撤销会拒绝执行并要求用户手工修复，而不是覆盖用户的内容。[插件管理器](../plugin-manager/README.zh.md#version-compatibility-and-exemptions)负责每次变更所需的授权、撤销与风险确认。

 ### Version compatibility and exemptions
 
-An install command that names packages (`add`, or `install` with specs) is checked before pnpm runs: a local path is read from its own `package.json`, and a registry spec is resolved through pnpm's registry lookup for the version its range selects and the peers that version declares. An incompatible DSH peer rejects the operation before pnpm runs, so nothing is downloaded and no build script runs; a build approval the caller supplied with the request is recorded before this check and remains. A git or tarball spec needs the fetch itself, so it is judged after installation: the operation then restores the profile manifest and lockfile, reinstalls the restored lockfile (or, when the profile had none, reinstalls from the restored manifest without creating one), and reports whether that recovery succeeded; already permitted build-script effects may remain. A dependency the run did not change never blocks an unrelated operation: it stays installed, the run reports a warning naming it, and profile startup denies it. Installation requests with `enabled: false` are checked the same way. Startup checks run independently; see [App boot](../app-boot/README.md#profiles) for range semantics. Version exemptions do not authorize dependency scripts.
+An install command that names packages (`add`, or `install` with specs) is checked before pnpm runs: a local path is read from its own `package.json`, and a registry spec is resolved through pnpm's registry lookup for the version its range selects and the `engines` and `peerDependencies` that version declares. An unmet DSH requirement rejects the operation before pnpm runs, so nothing is downloaded and no build script runs; a build approval the caller supplied with the request is recorded before this check and remains. A git or tarball spec needs the fetch itself, so it is judged after installation: the operation then restores the profile manifest and lockfile, reinstalls the restored lockfile (or, when the profile had none, reinstalls from the restored manifest without creating one), and reports whether that recovery succeeded; already permitted build-script effects may remain.

Installation requests with `enabled: false` are checked the same way. Startup checks run independently; see [App boot](../app-boot/README.md#profiles) for range semantics. Version exemptions do not authorize dependency scripts.
 
 An exemption is an exact `package-name@version` mapped to a list of exact DSH runtime versions in the profile's own `compatibility.json`, beside `package.json` and `cordis.patch.yml`. Writing it changes no dependency, no bundle selection, and no patch layer. Neither plugin upgrades nor DSH upgrades inherit permission. Use `plugin_manager` with `list_version_exemptions` to obtain the runtime version and saved grants, then `set_version_exemption` with `target`, `runtimeVersion`, and `enabled`. Granting also requires `acceptRisk: true`, only after warning the user that incompatible plugins may cause crashes or data loss and receiving explicit permission for that pair. The service checks the acknowledgement and versions, not conversation history. Revocation can remove historical runtime grants.
 
 A grant takes effect on the next composition. A live profile recomposes, so the granted plugin mounts in the running session and the result reports `applied`; a startup-only profile keeps its current entries until restart and reports `restart-required`.
 
-The CLI exposes `dsh plugin --profile <profile> version-exemptions`, `allow-version <package@version> --dsh-version <runtime> --accept-risk`, and `revoke-version <package@version> --dsh-version <runtime>`. A grant prints a risk warning before saving. A compatibility refusal carries the `incompatible-version` code with each refused package's `name`, `version`, `runtimeVersion`, and unsatisfied `peers`; each surface renders that record itself. The Web page words it through its locale dictionary, and a CLI refusal prints the exact `allow-version` command. Use the tool or CLI to grant an exemption and retry the original operation.

 豁免保存在 profile 自己的 `compatibility.json` 中（与 `package.json`、`cordis.patch.yml` 并列），将精确的 `package-name@version` 映射到精确 DSH 运行时版本列表。写豁免不改变依赖、组合包选择或 patch 层。插件升级和 DSH 升级都不继承授权。使用 `plugin_manager` 的 `list_version_exemptions` 获取运行时版本与已有授权，再通过 `set_version_exemption` 提交 `target`、`runtimeVersion` 和 `enabled`。授权还要求 `acceptRisk: true`；只能在警告用户不兼容插件可能导致崩溃或数据丢失，并获得用户对此版本组合的明确许可后传入。服务校验确认参数和版本，不核实对话历史。撤销可以移除历史运行时版本的授权。
 
 授权在下一次组合时生效。在线 profile 会重新组合，被授权的插件会在当前会话中挂载，结果报告 `applied`；仅启动型 profile 在重启前保留当前条目并报告 `restart-required`。

+## Summary
+
+`pluginMarket` reads the plugin market indexes the user configures, validates them with [`dsh-plugin-market-index`](../../util/plugin-market-index/README.md), and annotates every entry with the profile's installation status, DSH compatibility, and the exact arguments that install it. The Web [Discover tab](../../client/ui-plugin-market/README.md) and the `plugin_market` agent tool read through it; installation itself goes through [`pluginManager.installBundle`](../plugin-manager/README.md). The format and its rationale live in the [index format Agent Note](../../../.agents/notes/implemented/feature/2026-10-02-plugin-market-index-format.md); the Host and Web design lives in the [Discover Agent Note](../../../.agents/notes/implemented/feature/2026-10-02-plugin-market-discover.md).

+## Use this package
+
+The optional [custom plugin markets bundle](../../experimental/plugin-market-bundle/README.md) mounts the service as the `plugin-market` row; shipped profiles leave the bundle off. Like `plugin-manager`, the row is disabled without a profile, and it waits for `pluginManager`. No index source is configured by default, so the Host sends no market request until a user adds one.
+
+| Config | Default | Meaning |
+|---|---|---|
+| `indexes` | `[]` | Index URLs in display order. A usable URL is in canonical form and uses `http:` or `https:`, without credentials or fragment. The field is volatile: Discover, Settings, and `setIndexes` change it without remounting this service or `plugin-manager`. |
+| `fetchTimeoutMs` | `15000` | Deadline for one index fetch, including its body. |
+| `maxBytes` | `134217728` | Largest accepted index body. |
+| `cacheTtlMs` | `600000` | Lifetime of a successfully read document. |
+
+Settings and profile files can store any http(s) string, so the service validates each URL when it lists or reads it. `listIndexes` reports an unusable URL with its refusal, `search` and `entry` refuse it, and no request is sent to it; a repeated URL is listed once.
+
+The Remote methods are:
+
+- `listIndexes()` returns each configured URL with the title and description of its last successful read and, when the last read failed, its error. It never fetches.
+- `setIndexes(urls)` normalizes and validates each URL not already configured, keeps configured ones as written, refuses a repeated URL, and writes it through `settings.update` to this service's profile entry. It fails with `plugin-market/settings-unavailable` without Settings or a profile entry. The committed list is announced by `plugin-market/changed`.
+- `search(url, query)` accepts only a configured URL, so the service never fetches an arbitrary address. It returns one page of the plugins that match `query`, with the index title, description, and declarations, the document's `fetchedAt`, the `total` number of matches, and the `nextOffset`; each plugin carries its `defaultVersion` and `installation`, and each version its `install` and `compatibility`.
+
+The service method `entry(url, name)`, which is not a Remote method, returns one plugin of a configured index in the same form, or `undefined` when the index does not list it.
+
+A query selects plugins with every one of its conditions:
+
+| Field | Meaning |
+|---|---|
+| `text` | Fuzzy words; see below. Text without letters or digits selects every plugin. |
+| `category` | The plugin's category id. |
+| `labels` | Label ids the plugin must all have. An undeclared category or label id matches no plugin. |
+| `sort` | `index` order; `relevance`, best text match first and index order without text; latest `published` time; or a declared sort `key`, with plugins lacking the value last. Each takes `asc` or `desc` where it has a direction, and ties keep index order. An undeclared sort key leaves index order. |
+| `offset`, `limit` | The page: `offset` is a non-negative integer and `limit` an integer from 1 to 100; other values fail with `plugin-market/invalid-query`. |
+| `refresh` | Fetch again instead of using the cached document. |
+| `fetchedAt` | `fetchedAt` of an earlier page: answer from that document while it is cached, even after `cacheTtlMs`, so later pages continue the same results. |
+
+Text matches the package name, author, keywords, and every language of the title, description, and category and label titles. It is split into runs of letters, marks, and digits; a run of Chinese, Japanese, or Korean characters becomes its overlapping character pairs and its last character, so text written without spaces matches without a dictionary. Words are compared after NFKC normalization and without case. Every query word must match an indexed word as a prefix or, from four characters, within an edit distance of one fifth of its length rounded to the nearest integer, at most 2. Name and title matches weigh three times, and keyword matches twice, a match elsewhere.
+
+Failures use `plugin-market/invalid-query`, `plugin-market/invalid-index-url`, `plugin-market/unknown-index`, `plugin-market/fetch-failed`, and `plugin-market/invalid-index`; the last carries the JSON path of the offending value.
+
+The `plugin_market` tool lists the configured indexes, pages the plugins of one index in index order or, with a `query`, by best match, or pages one plugin's versions. It requires no approval because it reads only the sources the user configured and changes nothing; each version it returns carries the `target` and `registry` to pass to `plugin_manager`'s `install_bundle`, which keeps its own approval. The tool cannot change index sources. Creator mode keeps its row beside `plugin_manager`, and the row registers the tool only while `pluginMarket` is mounted; other presets keep it disabled.
+
+-----
+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+The Host fetches with the process `fetch`, so the configured outbound proxy applies, and refuses redirects. The body is read up to `maxBytes`, then a fresh Worker Thread decodes it as strict UTF-8, parses it as JSON, and validates it; relative icon references resolve against the configured URL. The body's buffer moves to the Worker, and the validated index returns to the Host by structured clone. The Worker is the self-contained `lib/worker.cjs` bundle; disposal terminates it, and a Worker failure is reported as `plugin-market/fetch-failed`.
+
+Concurrent reads of one URL share one fetch. A successful document is cached for `cacheTtlMs`; `refresh` bypasses the cache. Each fetched document gets a new `fetchedAt`, and the cached document stays answerable by its `fetchedAt` until a later fetch replaces it. A failed read records its message for `listIndexes` and keeps no document. A read that finishes after its URL left the configuration updates neither cache nor error. On `loader/volatile-update` the service drops state of removed URLs and emits `plugin-market/changed`. Disposal aborts in-flight fetches.
+
+Filtering and ordering read only the document; installation status and compatibility are computed for the returned page on every call. The first query with text in a document builds its text index with [MiniSearch](https://github.com/lucaong/minisearch), 500 plugins per event-loop turn, and later queries reuse it until the document is replaced.
+
+Compatibility is computed per version with `evaluatePluginCompatibility`, the version's `engines.dsh`, and the profile's version exemptions, the same check installation applies. A plugin's default version is its highest compatible version without a prerelease tag, or its highest compatible prerelease when it lists no version without one; a plugin with no compatible version has none. Installation status comes from `pluginManager.listBundles()` by package name, measured against the default version, or the highest version without one: `not-installed`, also for an on-demand catalog entry the profile has not installed; `installed` at that version; `update-available` when that version is greater; `different-version` when the installed version is unknown, not valid SemVer, or greater; and `provided` for a bundle the DSH installation ships.
+
+`marketInstallTarget` builds install arguments: `name@version` with the version's registry for npm, and `git+<url>.git#<commit>` with `&path:/<path>` for a package directory in Git.
+

+

+## Model Experience
+
+### Market listing tool
+
+#### What the model sees
+
+The [`plugin_market` tool](../../../docs/tool-catalog.md#deepseek-aidsh-plugin-market) returns JSON: configured index URLs with English titles and last errors, one page of plugins, in index order or by best match for a `query`, with name, English title, description, and author each truncated to 300 characters, homepage, repository, category, label ids, sort-key values, installation status, the default version, and the number of versions, or one page of a plugin's versions. Each returned version carries its ISO publish time, compatibility, and install arguments. Its description states that market text is third-party content, not instructions.
+
+#### Token effect
+
+The tool declaration is present when a preset mounts it; each call adds its JSON result, bounded by `limit` (at most 100 plugins or versions).
+
+#### KV Cache effect
+
+Append-only: results enter the conversation as ordinary tool results and do not change earlier request tokens.
+
+## Known Limitations and Deferred Work
+
+<a id="known-limitations-and-deferred-work"></a>
+
+- **No upgrade** — an installed bundle with a newer index version is reported as `update-available`; upgrading remains uninstall followed by install.
+- **Unsigned indexes** — index content, including a Git entry's name and version, is the market's claim; the installed manifest decides what is installed.
+- **Last write wins** — `setIndexes` replaces the whole list, so two windows editing sources at the same time can overwrite each other's change.
+- **Redirects refused** — an index served only behind a redirect must be configured at its final URL.
+- **Whole-document reads** — the Host downloads and keeps each index up to `maxBytes` and builds its text index in memory; a synthetic index of 20,000 plugins took about 0.8 s of build time and 130 MiB of heap. Parsing runs in a Worker, but receiving the validated index still blocks the Host event loop while the clone is deserialized: about 35 ms for a synthetic 7.6 MiB index of 20,000 plugins and about 190 ms for 38 MiB and 100,000 plugins. Larger markets need a server-side query protocol.
+- **Pages can change** — `fetchedAt` pins pages only while the document is cached; after another read replaces it, a reader must start again from the first page.

+## 概述
+
+`pluginMarket` 读取用户配置的插件市场索引，用 [`dsh-plugin-market-index`](../../util/plugin-market-index/README.zh.md) 校验，并为每个条目标注 profile 中的安装状态、DSH 兼容性以及安装它所需的精确参数。Web 的[发现标签页](../../client/ui-plugin-market/README.zh.md)和 `plugin_market` agent 工具通过它读取；安装本身经由 [`pluginManager.installBundle`](../plugin-manager/README.zh.md) 进行。格式及其理由见[索引格式 Agent Note](../../../.agents/notes/implemented/feature/2026-10-02-plugin-market-index-format.zh.md)；Host 与 Web 的设计见[发现 Agent Note](../../../.agents/notes/implemented/feature/2026-10-02-plugin-market-discover.zh.md)。

+## 使用本包
+
+可选的[自定义插件市场组合包](../../experimental/plugin-market-bundle/README.zh.md)把该服务挂载为 `plugin-market` 行；随附的 profile 默认不启用该组合包。与 `plugin-manager` 一样，该行在没有 profile 时被禁用，并等待 `pluginManager`。默认不配置任何索引源，因此在用户添加索引源之前，Host 不发送任何市场请求。
+
+| 配置 | 默认值 | 含义 |
+|---|---|---|
+| `indexes` | `[]` | 按显示顺序排列的索引 URL。可用的 URL 采用规范形式，使用 `http:` 或 `https:`，不含凭据或片段。该字段是 volatile 字段：发现区、设置和 `setIndexes` 修改它时，不会重新挂载本服务或 `plugin-manager`。 |
+| `fetchTimeoutMs` | `15000` | 单次索引获取（包括响应体）的时限。 |
+| `maxBytes` | `134217728` | 接受的最大索引响应体。 |
+| `cacheTtlMs` | `600000` | 成功读取的文档的缓存时长。 |
+
+设置和 profile 文件可以存储任意 http(s) 字符串，因此服务在列出或读取每个 URL 时校验它。`listIndexes` 报告不可用的 URL 及其拒绝原因，`search` 和 `entry` 拒绝该 URL，且不会向它发送请求；重复的 URL 只列出一次。
+
+Remote 方法如下：
+
+- `listIndexes()` 返回每个已配置 URL，以及其最近一次成功读取得到的标题和描述；最近一次读取失败时，还返回其错误。它从不发起获取。
+- `setIndexes(urls)` 规范化并校验每个尚未配置的 URL，已配置的 URL 保持原样，拒绝重复的 URL，并通过 `settings.update` 把列表写入本服务的 profile 条目。没有 Settings 或 profile 条目时，以 `plugin-market/settings-unavailable` 失败。提交后的列表通过 `plugin-market/changed` 通告。
+- `search(url, query)` 只接受已配置的 URL，因此服务从不获取任意地址。它返回匹配 `query` 的一页插件，并附带索引的标题、描述和声明、该文档的 `fetchedAt`、匹配总数 `total` 和 `nextOffset`；每个插件携带 `defaultVersion` 和 `installation`，每个版本携带 `install` 和 `compatibility`。
+
+服务方法 `entry(url, name)` 不是 Remote 方法，它以相同形式返回已配置索引中的一个插件；索引未列出该插件时返回 `undefined`。
+
+查询选出同时满足其全部条件的插件：
+
+| 字段 | 含义 |
+|---|---|
+| `text` | 模糊匹配的词，见下文。不含字母或数字的文本选出所有插件。 |
+| `category` | 插件的分类 id。 |
+| `labels` | 插件必须全部具备的标签 id。未声明的分类或标签 id 不匹配任何插件。 |
+| `sort` | `index` 为索引顺序；`relevance` 为文本匹配最好的在前，没有文本时为索引顺序；`published` 为最新发布时间；`key` 为已声明的排序键，缺少该值的插件排在最后。有方向的排序取 `asc` 或 `desc`，相同时保持索引顺序。未声明的排序键保持索引顺序。 |
+| `offset`、`limit` | 页：`offset` 是非负整数，`limit` 是 1 到 100 的整数；其他值以 `plugin-market/invalid-query` 失败。 |
+| `refresh` | 重新获取，而不使用缓存的文档。 |
+| `fetchedAt` | 先前某页的 `fetchedAt`：只要该文档仍在缓存中，即使超过 `cacheTtlMs` 也用它回答，使后续页延续同一份结果。 |
+
+文本匹配包名、作者、关键词，以及标题、描述、分类标题和标签标题的所有语言。文本被拆分为由字母、组合符号和数字构成的连续片段；由中文、日文或韩文字符构成的片段变为相邻的两字组合及其最后一个字符，因此不带空格书写的文本无需词典也能匹配。词在 NFKC 规范化后不区分大小写地比较。查询中的每个词都必须匹配某个已索引的词，可以是前缀，或者在词长至少四个字符时，编辑距离不超过其长度的五分之一（四舍五入），且最多为 2。名称和标题匹配的权重是其他位置的三倍，关键词匹配是两倍。
+
+失败使用 `plugin-market/invalid-query`、`plugin-market/invalid-index-url`、`plugin-market/unknown-index`、`plugin-market/fetch-failed` 和 `plugin-market/invalid-index`；最后一种携带违规值的 JSON 路径。
+
+`plugin_market` 工具列出已配置的索引，按索引顺序分页列出某个索引的插件，或在给出 `query` 时按最佳匹配分页列出，或分页列出某个插件的版本。它不需要批准，因为它只读取用户配置的源且不做任何改动；它返回的每个版本都携带要传给 `plugin_manager` 的 `install_bundle` 的 `target` 和 `registry`，`install_bundle` 仍保留自己的批准要求。该工具不能修改索引源。Creator 模式在 `plugin_manager` 旁边保留它的行，该行只在 `pluginMarket` 已挂载时注册工具；其他预设保持禁用。
+
+-----
+
+<a id="understand-the-implementation"></a>
+## 理解实现
+
+Host 使用进程的 `fetch` 获取，因此配置的出站代理生效，并拒绝重定向。响应体最多读取 `maxBytes`，随后由一个新的 Worker Thread 按严格 UTF-8 解码、解析为 JSON 并校验；相对图标引用基于配置的 URL 解析。响应体的缓冲区转移给 Worker，校验后的索引通过 structured clone 返回 Host。Worker 是自包含的 `lib/worker.cjs` bundle；销毁时终止它，Worker 失败报告为 `plugin-market/fetch-failed`。
+
+对同一 URL 的并发读取共享一次获取。成功的文档缓存 `cacheTtlMs`；`refresh` 绕过缓存。每份获取到的文档都有新的 `fetchedAt`，缓存的文档在被之后的获取替换前，都可以按其 `fetchedAt` 回答。失败的读取为 `listIndexes` 记录错误消息，不保留文档。读取完成时其 URL 已不在配置中的，既不更新缓存也不更新错误。收到 `loader/volatile-update` 时，服务丢弃已移除 URL 的状态并发出 `plugin-market/changed`。销毁时中止进行中的获取。
+
+过滤和排序只读取文档；安装状态和兼容性在每次调用时只为返回的页计算。一份文档上第一次带文本的查询使用 [MiniSearch](https://github.com/lucaong/minisearch) 构建其文本索引，每轮事件循环处理 500 个插件，之后的查询复用该索引，直到文档被替换。
+
+兼容性按版本计算：使用 `evaluatePluginCompatibility`，传入该版本的 `engines.dsh` 和 profile 的版本豁免，与安装时执行的检查相同。插件的默认版本是其不带先行版本号的最高兼容版本；插件完全没有此类版本时，使用其最高兼容的先行版本；没有兼容版本的插件没有默认版本。安装状态按包名根据 `pluginManager.listBundles()` 计算，以默认版本为准，没有默认版本时以最高版本为准：`not-installed`（包括当前 profile 尚未安装的按需目录条目）；版本相同时为 `installed`；该版本更高时为 `update-available`；已安装版本未知、不是有效的 SemVer 或更高时为 `different-version`；DSH 安装随附的组合包（bundle）为 `provided`。
+
+`marketInstallTarget` 构建安装参数：npm 为 `name@version` 加该版本的 registry，Git 为 `git+<url>.git#<commit>`，包位于子目录时追加 `&path:/<path>`。

+## 模型体验
+
+### 市场列表工具
+
+#### 模型看到什么
+
+[`plugin_market` 工具](../../../docs/tool-catalog.zh.md#deepseek-aidsh-plugin-market)返回 JSON：已配置的索引 URL 及其英文标题和最近错误，一页插件（按索引顺序，或给出 `query` 时按最佳匹配），包含名称、英文标题、描述和作者（各截断为 300 个字符）、主页、仓库、分类、标签 id、排序键值、安装状态、默认版本和版本数量，或者某个插件的一页版本。返回的每个版本都携带 ISO 发布时间、兼容性和安装参数。其描述声明市场文本是第三方内容，不是指令。
+
+#### Token 影响
+
+预设挂载该工具时提供工具声明；每次调用追加其 JSON 结果，大小受 `limit` 限制（最多 100 个插件或版本）。
+
+#### KV Cache 影响
+
+仅追加：结果作为普通工具结果进入对话，不改变先前的请求 token。
+
+## 已知限制与延期工作
+
+<a id="known-limitations-and-deferred-work"></a>
+
+- **不支持升级**——索引版本更新的已安装组合包报告为 `update-available`；升级仍需先卸载再安装。
+- **索引没有签名**——索引内容（包括 Git 条目的名称和版本）是市场的声明；实际安装什么由已安装的 manifest（元数据清单）决定。
+- **后写入者覆盖**——`setIndexes` 会替换整个列表，因此两个窗口同时编辑索引源时，可能互相覆盖对方的修改。
+- **拒绝重定向**——只能经重定向访问的索引必须以其最终 URL 配置。
+- **读取整份文档**——Host 下载并保留每个不超过 `maxBytes` 的索引，并在内存中构建其文本索引；一个包含 20,000 个插件的合成索引构建用时约 0.8 秒，占用约 130 MiB 堆内存。解析在 Worker 中运行，但接收校验后的索引时，反序列化 clone 仍会阻塞 Host 事件循环：包含 20,000 个插件的 7.6 MiB 合成索引约 35 毫秒，包含 100,000 个插件的 38 MiB 索引约 190 毫秒。更大的市场需要服务端查询协议。
+- **分页可能变化**——`fetchedAt` 只在文档仍被缓存时固定分页；另一次读取替换文档后，读取方必须从第一页重新开始。

 A row's page exists only while a `plugins.row.config` entry names the row, so a contribution meant for a row renders on the page that configuration opens.
 
+### Page tabs
+
+Another plugin adds a tab after the page's own **Installed** tab by registering into the `plugins.tab` list slot; the entry's `label` names the tab and `order` places it. The tabs appear under the page header once one entry exists and are hidden on a bundle's, row's, or official plugin's page; the selected tab survives leaving **Plugins**, and a tab whose entry leaves falls back to **Installed**. The page renders the selected entry in place of its groups and hides its own refresh and add buttons there. The owner props carry `install({ spec, registry?, title, version })` and `openPackage(name)`. `install` is for a version the person already confirmed in the tab: the install dialog opens at its check screen, without the spec form, names the plugin with `title` and `version` above the spec, which it shows in smaller monospace text, keeps that name on the progress and result screens, with the installed version once done, asks `registry` first for that install only and never remembers it, and offers **Retry** after a refusal; a hidden installation reopens instead. `openPackage` switches to **Installed** and opens the bundle's page when that tab lists it; a bundle the page leaves out, such as a built-in profile bundle, leaves the Installed list open. A confirmed install offers no GitHub mirror recovery, since that recovery reopens the spec form, and its back button cancels a running install. [`ui-plugin-market`](../ui-plugin-market/README.md) contributes the **Discover** tab here.

+
+## Summary
+
+Discover is the second tab of the **Plugins** page, after **Installed**. It lists the bundles that plugin market indexes offer; users manage index sources, switch between markets, search, filter by category and label, sort, open an entry's page, and install an entry after confirming it. The Host [`pluginMarket`](../../boot/plugin-market/README.md) service fetches and validates indexes; this package only presents them.

+
+-----
+
+<a id="use-this-package"></a>
+## Use this package
+
+Open **Plugins** and select **Discover**. With no index source, the tab shows an empty state whose **Add index source** button opens the **Index sources** dialog. The dialog lists each source by market title, or by host before the first read, with its URL, the error of its last failed read, and a remove button, and keeps a notice that indexes come from third parties. A refused URL keeps the draft and says why: an unsupported scheme, credentials, or fragment; a URL already listed; or a deployment that cannot save sources. A newly added source becomes the selected market.
+
+The toolbar holds the market menu, which switches markets and ends with **Manage index sources…**; the search field; a **Labels** menu with multi-select checkmarks when the market declares labels; the **Sort** menu; and a refresh button. Category pills, with **All** first, follow when the market declares categories.
+
+Each card shows the icon, localized title, label tags, a one-line description, and the default version, author, and publish date, with one action: **Install** for an installable entry; a disabled **Install** whose tooltip says no version is compatible with the running DSH when the plugin has no default version and its highest version is neither compatible nor exempted; or **Installed**, **Update available**, or **Provided by DSH**, which switches to the Installed tab and opens that bundle's page when that tab lists it. Selecting a card opens the entry's page with its full description, compatibility notice, and the default version's facts: author; homepage and source code repository, as links that open in a new tab, with the package directory beside the repository; the npm package and registry, or the Git repository, full commit, and directory; publish date; category; labels; and market. A **Versions** list follows in descending SemVer order; each row tags the recommended, prerelease, installed, incompatible, and exempted versions and offers **Install** for any other version installation accepts, except for a bundle DSH provides. The page's back link returns to the list with its search, filters, and sort intact.
+
+**Install** chooses the default version and opens a confirmation dialog with the entry's icon, title, that version, the author, its source facts, an exemption notice when one applies, and a trust notice. Confirming opens the Plugins install dialog at its check screen with the entry's exact spec and registry; there is no spec form, and a refusal offers **Retry**. The registry an entry names applies to that install only.
+
+The Host [`pluginMarket.search`](../../boot/plugin-market/README.md#use-this-package) matches, filters, orders, and pages; the tab sends the search text 250 ms after typing stops. Search matches names, authors, keywords, and every language of titles, descriptions, categories, and labels, fuzzily. Label filters must all match. **Sort** offers **Best match** while there is search text, **Default order**, **Publish date**, and each declared sort key, which starts in its declared direction; a directed sort adds a row that reverses it. Typing switches **Default order** to **Best match**, and clearing the text switches back. Categories, labels, and sort keys are listed by localized title. The list loads 50 entries and adds 50 with each **Show more**.
+
+Reading a market shows card skeletons. A failed read shows a short sentence with **Retry**, the Host's reason appears under the source in **Index sources**, and keeps the market's last listing; a failed read of the source list shows **Retry** in place of the tab. Discover re-reads sources on `plugin-market/changed` and connection reset, and recomputes installation status on `plugin-manager/changed`.
+
+-----
+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+The plugin registers the `discover` entry, labelled **Discover**, into `plugins.tab`, the tab slot that [`ui-plugin-manager`](../ui-plugin-manager/README.md) declares; the owner props provide `install({ spec, registry?, title, version })` and `openPackage(name)`; Discover passes the entry's localized title and the chosen version. A React-free controller owns source reads, source edits, and the selected index's query and loaded pages in a snapshot store; selecting another market starts from the initial query. Later pages send the first page's `fetchedAt`, and a page from a replaced document reloads the list once; a second replacement fails the read. The listing keeps the query its results answer, so the empty-state wording follows the shown results while a new query loads or after it fails, and **Retry** repeats the read that failed: the first pages of a query or the next page. A change to the profile's bundles reloads every loaded page to refresh installation status, and a filter or sort key the index no longer declares leaves the query. The unsent search text, the open entry, and the confirmation are component state. Pure helpers in `presentation.ts` derive the query order from the text, drop undeclared ids, order declarations with `Intl.Collator` in the active UI language, and list source facts. Icons load lazily with `referrerpolicy="no-referrer"` and fall back to the default artwork.

+
+## 概述
+
+「发现」是**插件**页的第二个标签页，位于**已安装**之后。它列出插件市场索引提供的组合包（bundle）；用户可以管理索引源、在插件市场之间切换、搜索、按分类和标签筛选、排序、打开条目页面，并在确认后安装条目。Host 的 [`pluginMarket`](../../boot/plugin-market/README.zh.md) 服务负责获取和校验索引；本包只负责展示。
+
+## 目录
+
+- [使用本包](#use-this-package)
+- [理解实现](#understand-the-implementation)
+- [模型体验](#model-experience)
+- [已知限制与延期工作](#known-limitations-and-deferred-work)
+- [开发备注](#dev-note)
+
+-----
+
+<a id="use-this-package"></a>
+## 使用本包
+
+打开**插件**并选择**发现**。没有索引源时，该标签页显示空状态，其中的**添加索引源**按钮打开**索引源**对话框。对话框按插件市场标题列出每个索引源（首次读取前按主机名），并显示其 URL、最近一次读取失败的错误和删除按钮，同时保留一条提示，说明索引由第三方提供。URL 被拒绝时保留草稿并说明原因：不支持的协议、包含凭据或片段、URL 已在列表中，或当前部署无法保存索引源。新添加的索引源成为所选插件市场。
+
+工具栏包含：插件市场菜单，用于切换插件市场，最后一项为**管理索引源…**；搜索框；插件市场声明了标签时显示的**标签**菜单，以勾选标记支持多选；**排序**菜单；以及刷新按钮。插件市场声明了分类时，其后显示分类按钮，**全部**排在第一位。
+
+每张卡片显示图标、本地化标题、标签、一行描述，以及默认版本、作者和发布日期，并只有一个操作：可安装的条目显示**安装**；没有默认版本、且最高版本既不兼容也未豁免的条目显示禁用的**安装**，其提示框说明没有与当前运行的 DSH 兼容的版本；其余条目显示**已安装**、**有新版本**或**随 DSH 提供**，点击后切换到「已安装」标签页，并在该标签页列出该组合包时打开其页面。选择卡片会打开条目页面，显示其完整描述、兼容性提示和默认版本的信息：作者；主页和源代码仓库（在新标签页中打开的链接，仓库旁显示包所在目录）；npm 包和注册表，或 Git 仓库、完整提交和目录；发布日期；分类；标签；以及插件市场。其后是按 SemVer 降序排列的**版本**列表；每行标出推荐、预发布、已安装、不兼容和已豁免的版本，并为安装检查接受的其他版本提供**安装**，DSH 随附的组合包除外。页面的返回链接回到列表，搜索、筛选和排序保持不变。
+
+**安装**选择默认版本并打开确认对话框，显示条目的图标、标题、该版本、作者、来源信息、适用时的豁免提示，以及信任提示。确认后，插件页的安装对话框以该条目的精确 spec 和注册表在检查界面打开；不显示 spec 表单，被拒绝时提供**重试**。条目指定的注册表只用于这一次安装。
+
+Host 的 [`pluginMarket.search`](../../boot/plugin-market/README.zh.md#use-this-package) 负责匹配、过滤、排序和分页；标签页在停止输入 250 毫秒后发送搜索文本。搜索模糊匹配名称、作者、关键词，以及标题、描述、分类和标签的所有语言。所选标签必须全部匹配。有搜索文本时，**排序**提供**最佳匹配**，此外还提供**默认顺序**、**发布时间**以及每个已声明的排序键，排序键以其声明的方向开始；有方向的排序会额外显示一行，用于反转方向。输入文本会把**默认顺序**切换为**最佳匹配**，清空文本时切换回来。分类、标签和排序键按本地化标题列出。列表加载 50 个条目，每次点击**显示更多**再增加 50 个。
+
+读取插件市场时显示卡片骨架屏。读取失败时显示一句简短说明和**重试**，Host 给出的原因显示在**索引源**中对应索引源的下方，并保留该插件市场上一次的列表；读取索引源列表失败时，在该标签页的位置显示**重试**。「发现」在收到 `plugin-market/changed` 和连接重置时重新读取索引源，在收到 `plugin-manager/changed` 时重新计算安装状态。
+
+-----
+
+<a id="understand-the-implementation"></a>
+## 理解实现
+
+本插件把标签为**发现**的 `discover` 条目注册到 `plugins.tab`，即 [`ui-plugin-manager`](../ui-plugin-manager/README.zh.md) 声明的标签页 slot；owner props 提供 `install({ spec, registry?, title, version })` 和 `openPackage(name)`；发现页传入条目的本地化标题和所选版本。一个不依赖 React 的控制器在快照存储中拥有索引源读取、索引源编辑，以及所选索引的查询和已加载的页；选择另一个插件市场时从初始查询开始。之后的页发送第一页的 `fetchedAt`，来自已替换文档的页会让列表重新加载一次；再次被替换时读取失败。列表保留其结果所回答的查询，因此新查询加载期间或失败后，空状态文案仍与显示的结果一致；**重试**重新执行失败的读取：某个查询的前几页，或下一页。profile 的组合包变化时，重新加载所有已加载的页以刷新安装状态；索引不再声明的过滤条件或排序键会从查询中移除。尚未发送的搜索文本、打开的条目和确认对话框是组件状态。`presentation.ts` 中的纯函数根据文本得出查询顺序、移除未声明的 id、使用当前界面语言的 `Intl.Collator` 对声明排序，以及列出来源信息。图标以 `referrerpolicy="no-referrer"` 延迟加载，失败时回退到默认插画。

+## Summary
+
+This optional bundle mounts custom plugin markets: the Host [`pluginMarket`](../../boot/plugin-market/README.md) service, which reads the plugin market indexes the user adds, and the Web [Discover tab](../../client/ui-plugin-market/README.md) of the Plugins page. Shipped profiles leave it disabled.

+## Use this package
+
+Open **Plugins** in the Web sidebar, select **More** beside **Experimental plugins**, and switch on **Custom plugin markets**; once on, it also appears on the main list. The page then shows the **Installed** and **Discover** tabs; **Discover** adds index sources and installs their bundles. Switching the bundle off removes the Discover tab and the `plugin_market` tool; the saved index sources stay in the profile.

+## Understand the implementation
+
+<details>
+<summary>Maintainer details — click to expand</summary>
+
+The static `cordis.patch.yml` inserts the `plugin-market` service row, disabled without a profile like `plugin-manager`, and the `ui-plugin-market` browser row. The Creator preset keeps its `tool-plugin-market` row; that plugin registers `plugin_market` only while `pluginMarket` is mounted, so the row neither waits nor shows the tool without this bundle. The Plugins page shows its tabs only when a `plugins.tab` entry exists, so it needs no knowledge of this bundle.
+
+</details>
+
+-----
+
+<a id="model-experience"></a>
+## Model Experience
+
+Indirectly, through the `pluginMarket` service: with the bundle switched on, the Creator preset gains the read-only `plugin_market` tool documented in [`dsh-plugin-market`](../../boot/plugin-market/README.md#model-experience).
+
+#### KV Cache effect
+
+Switching the bundle on or off adds or removes one tool schema in Creator sessions, which changes the cached request prefix of later requests.
+
+## Known Limitations and Deferred Work
+
+<a id="known-limitations-and-deferred-work"></a>
+
+- There is no official market; Discover lists only the index sources the user adds.

+
+## 概述
+
+此可选组合包（bundle）挂载自定义插件市场：Host 的 [`pluginMarket`](../../boot/plugin-market/README.zh.md) 服务读取用户添加的插件市场索引，Web 端提供插件页的[发现标签页](../../client/ui-plugin-market/README.zh.md)。随包配置默认禁用。

+## 使用此包
+
+打开 Web 侧栏中的**插件**，点击**实验性插件**旁的**更多**，启用**自定义插件市场**；启用后它也会出现在主列表中。页面随后显示**已安装**和**发现**两个标签页；**发现**用于添加索引源并安装其中的组合包。禁用此组合包会移除发现标签页和 `plugin_market` 工具；已保存的索引源保留在 profile 中。
+
+-----
+
+<a id="understand-the-implementation"></a>
+## 理解实现
+
+<details>
+<summary>维护者信息 — 点击展开</summary>
+
+静态 `cordis.patch.yml` 插入 `plugin-market` 服务行和 `ui-plugin-market` 浏览器行；与 `plugin-manager` 一样，服务行在没有 profile 时被禁用。Creator 预设保留其 `tool-plugin-market` 行；该插件只在 `pluginMarket` 已挂载时注册 `plugin_market`，因此没有此组合包时，该行既不等待，也不显示该工具。插件页只在存在 `plugins.tab` 条目时显示标签页，因此无需了解此组合包。
+
+</details>
+
+-----
+
+<a id="model-experience"></a>
+## 模型体验
+
+该包通过 `pluginMarket` 服务间接影响模型：启用此组合包后，Creator 预设获得只读的 `plugin_market` 工具，其说明见 [`dsh-plugin-market`](../../boot/plugin-market/README.zh.md#model-experience)。
+
+#### KV Cache 影响
+
+启用或禁用此组合包会在 Creator 会话中增加或移除一个工具 schema，从而改变后续请求的缓存请求前缀。
+
+## 已知限制与后续工作
+
+<a id="known-limitations-and-deferred-work"></a>
+
+- 目前没有官方插件市场；发现标签页只列出用户添加的索引源。

+
+## Summary
+
+Validator without runtime dependencies for format 1 of the plugin market index, the single JSON file that lists installable DSH bundles with their display metadata. [The format Agent Note](../../../.agents/notes/implemented/feature/2026-10-02-plugin-market-index-format.md) defines the document; this package is its executable rule set. DSH's [`dsh-plugin-market`](../../boot/plugin-market/README.md) reads indexes with it, and index generators validate their output with it before publishing.

+## Use this package
+
+It is a library, not a service or plugin: no `ctx`, no registrations, no state, no I/O.
+
+Parse the fetched document as JSON, then pass the value and the URL it was read from to `parseMarketIndex`. The first violated rule throws `MarketIndexError` with the JSON path of the offending value. A successful result drops members the format does not define, fills absent `metadata` groups, `keywords`, `labels`, `sortKeys`, and `engines` with empty values, orders each plugin's `versions` by descending SemVer precedence, and replaces each relative `icon` reference with its absolute URL.
+
+Install one version with `marketInstallTarget(name, version)`: it returns the exact pnpm spec, `name@version` for npm and a commit-pinned `git+https` URL with an optional `path:` parameter for Git, and the registry to ask first when the version names one.
+
+-----
+
+<a id="api"></a>
+## API
+
+```ts
+import { MarketIndexError, marketInstallTarget, parseMarketIndex } from '@deepseek-ai/dsh-plugin-market-index'
+```
+
+| Export | Role |
+|---|---|
+| `parseMarketIndex(value, indexUrl)` | Validated `MarketIndex`; throws `MarketIndexError` for the first violated rule. |
+| `marketInstallTarget(name, version)` | `{ spec, registry? }` that installs that exact version. |
+| `MarketIndexError` | Validation failure carrying `path` and `reason`. |
+| `MAX_INLINE_ICON_BYTES` | Largest decoded payload of an inline `data:` icon, 32 KiB. |
+| `MarketIndex`, `MarketPlugin`, `MarketVersion`, `MarketEngines`, `MarketSource`, `MarketRepository`, `MarketIndexMetadata`, `MarketPluginMetadata`, `MarketDeclaration`, `MarketSortKeyDeclaration`, `MarketInstallTarget` | Validated record types. |
+
+<a id="model-experience"></a>
+## Model Experience
+
+Indirectly, through `dsh-plugin-market`, whose `plugin_market` tool returns validated plugins to the model.
+
+#### KV Cache effect
+
+None of its own. The tool result that carries plugins owns its request's cache behavior.
+
+## Known Limitations and Deferred Work
+
+<a id="known-limitations-and-deferred-work"></a>
+
+- **Generator obligations are unchecked** — the validator cannot verify that `name`, `version`, `publishTimestamp`, `engines.dsh`, or display fields match the package they describe, or that the package declares a bundle.
+- **No size bound** — the caller bounds the document before parsing it.

+
+[English](README.md) | 中文
+
+## 概述
+
+插件市场索引格式 1 的校验器，没有运行时依赖。插件市场索引是一份 JSON 文件，列出可安装的 DSH 组合包（bundle）及其展示元数据。[格式 Agent Note](../../../.agents/notes/implemented/feature/2026-10-02-plugin-market-index-format.zh.md) 定义该文档；本包是其可执行的规则集。DSH 的 [`dsh-plugin-market`](../../boot/plugin-market/README.zh.md) 用它读取索引，索引生成器在发布前用它校验输出。
+
+## 目录
+
+- [使用本包](#use-this-package)
+- [API](#api)
+- [模型体验](#model-experience)
+- [已知限制与延期工作](#known-limitations-and-deferred-work)
+- [开发备注](#dev-note)

+## 使用本包
+
+本包是库，不是服务或插件：没有 `ctx`、没有注册、没有状态，也没有 I/O。
+
+先把获取到的文档解析为 JSON，再把该值和读取它的 URL 传给 `parseMarketIndex`。遇到第一条被违反的规则时，它抛出 `MarketIndexError`，并附带违规值的 JSON 路径。成功的结果会丢弃格式未定义的成员，用空值填充缺失的 `metadata` 分组、`keywords`、`labels`、`sortKeys` 和 `engines`，按 SemVer 优先级降序排列每个插件的 `versions`，并把每个相对 `icon` 引用替换为其绝对 URL。
+
+使用 `marketInstallTarget(name, version)` 安装一个版本：它返回精确的 pnpm spec（npm 为 `name@version`，Git 为固定到提交、可带 `path:` 参数的 `git+https` URL），该版本指定了 registry 时还返回首先询问的 registry。
+
+-----
+
+<a id="api"></a>
+## API
+
+```ts
+import { MarketIndexError, marketInstallTarget, parseMarketIndex } from '@deepseek-ai/dsh-plugin-market-index'
+```
+
+| 导出 | 作用 |
+|---|---|
+| `parseMarketIndex(value, indexUrl)` | 经过校验的 `MarketIndex`；遇到第一条被违反的规则时抛出 `MarketIndexError`。 |
+| `marketInstallTarget(name, version)` | 安装该精确版本的 `{ spec, registry? }`。 |
+| `MarketIndexError` | 携带 `path` 和 `reason` 的校验失败。 |
+| `MAX_INLINE_ICON_BYTES` | 内联 `data:` 图标解码后载荷的最大字节数，即 32 KiB。 |
+| `MarketIndex`, `MarketPlugin`, `MarketVersion`, `MarketEngines`, `MarketSource`, `MarketRepository`, `MarketIndexMetadata`, `MarketPluginMetadata`, `MarketDeclaration`, `MarketSortKeyDeclaration`, `MarketInstallTarget` | 经过校验的记录类型。 |
+
+<a id="model-experience"></a>
+## 模型体验
+
+间接存在：通过 `dsh-plugin-market`，其 `plugin_market` 工具把经过校验的插件返回给模型。
+
+#### KV Cache 影响
+
+本包自身没有。携带插件的工具结果决定其请求的缓存行为。
+
+## 已知限制与延期工作
+
+<a id="known-limitations-and-deferred-work"></a>
+
+- **不检查生成器义务**——校验器无法验证 `name`、`version`、`publishTimestamp`、`engines.dsh` 或展示字段是否与其描述的包一致，也无法验证该包是否声明了组合包。
+- **没有大小上限**——调用方在解析前限制文档大小。
