+
+## Problem
+
+Client feature plugins can share React components only through `@deepseek-ai/dsh-client-ui-primitives`, but file cards had no shared file-type presentation. `LinkIcon` owned the only extension table and deliberately collapsed paths into six link categories, while attachment cards, sent-message attachments, queued files, and workspace file rows used one generic document glyph. Two of those consumers also carried separate extension-display helpers. Adding a precise file icon anywhere else would have required another extension table or a runtime import between feature plugins.
+
+## Decision
+
+`ui-primitives` owns one Cordis-free file classification and rendering API. `fileExtension(path)` applies the shared basename and final-dot semantics to either path separator. `classifyFileType(path)` matches without case sensitivity and returns the closed `FileType` union: the traditional `code`, `excel`, `folder`, `html`, `image`, `markdown`, `other`, `pdf`, `ppt`, `video`, and `word` categories plus the detailed `CodeFileType` set imported from the supplied `square-code-icons` map. Exact filenames, filename prefixes, filename suffixes, optional project context, and extensions run in that order. The path classifier returns every member except `folder`; callers use the explicit `FileTypeIcon` `type` override when they know an entry is a directory. Unknown extensions, missing extensions, and trailing dots resolve to `other`, except the shared table recognizes named files such as `Dockerfile`, `Makefile`, `package.json`, `.gitignore`, `README`, and `CHANGELOG`.
+
+`FileTypeIcon` accepts a path, shared `IconProps`, the optional explicit type, and an optional project-file snapshot. Traditional file types render the supplied 28px document and folder contours as inline SVG. Excel, Markdown, PDF, PPT, and Word foreground marks scale to 122% around their visual center; the remaining marked traditional glyphs use 112%, while the file body and folded corner retain their source geometry and the generic file has no invented center mark. The sheet is a solid category color, the foreground mark and ordinary folded corner are white, and the generic file has a darker grey corner. CSS assigns the supplied category palette through static design tokens: DeepSeek blue for code/HTML/Markdown, the lighter DeepSeek blue for Word, green for Excel, two amber steps for folder/PPT, red for PDF, and neutral grey for unknown files. Image and video share the supplied violet through a component-local variable because the design platform has no matching violet token. A caller may override a traditional sheet through `--dsh-file-type-icon-color`.
+
+Recognized code and configuration files render the corresponding 20px square artwork scaled to the requested icon size. These technology marks retain their embedded multicolor fills and are the explicit exception to the ordinary current-color icon rule. The map selects React before TypeScript/JavaScript, Angular filename suffixes before their base extension, Docker/Node/Git/Make/CMake by filename rules, and Flutter only when the optional project snapshot contains a `pubspec.yaml` whose text includes `flutter:`. Markdown and SVG remain owned by the traditional Markdown and image categories. Every traditional and technology SVG is `aria-hidden`, and the card, row, or button that owns the file identity supplies the accessible name.
+
+`LinkIcon` delegates extension classification to `classifyFileType` and folds the detailed result into its existing link vocabulary: code and HTML use `code`, images use `image`, PDF/Word/Excel/PPT use `document`, and Markdown/video/unknown files use `other`. Extensionless names remain `other` in link contexts, so the 14px clickable-link appearance defined by the [clickable-link decision](2026-09-04-web-clickable-link-styles.md) does not change.
+
+Attachment upload cards, sent-message file cards, queued-file rows, and workspace file rows render `FileTypeIcon`. The two metadata rows use `fileExtension` rather than local parsers; a leading-dot basename such as `.env` therefore displays `ENV`, while an absent or trailing suffix displays no extension label. Image content continues to render as a preview rather than a file-type glyph, and produced-file links and Markdown file mentions continue to use `LinkIcon` because they are link surfaces.
+
+## Alternatives considered
+
+**Use `LinkIcon` for every file surface.** Rejected. Its six categories and 14px outline drawings communicate link destinations at text size; a 28px file card has room for the supplied HTML, Markdown, PDF, Word, Excel, PPT, and video identities.
+
+**Keep a second extension table beside `LinkIcon`.** Rejected. The same path could drift to different categories as either list grows. One detailed table plus an explicit detailed-to-link adapter preserves both consumers' semantics.
+
+**Put the supplied traditional-file colors directly in each SVG path.** Rejected. Traditional SVG geometry stays reusable and follows the icon set's `currentColor` rule; the component stylesheet owns the default category palette, and render sites retain one CSS-variable override instead of rewriting path fills. The technology artwork is exempt because its embedded multicolor marks identify the language or tool rather than decorating a generic file silhouette.
+
+**Add archive, audio, and data categories for symmetry.** Rejected. The supplied artwork and current consumers require no such glyphs. New `FileType` members require a shipped render site and artwork that remains legible at the 28px seat.
+
+## Testing
+
+The `ui-primitives` specs cover case-insensitive suffixes, both path separators, leading-dot files, missing and trailing suffixes, common named files, unknown fallback, all detailed code mappings, rule priority, Flutter context, every supplied technology SVG, instance-safe gradient ids, `aria-hidden`, sizing/class forwarding, distinct artwork, the 112% and 122% foreground-mark transforms, and the traditional solid-sheet/contrast-mark layers without literal SVG colors. A stylesheet spec pins every traditional category-to-color mapping, the caller override, and the local violet value. The existing `LinkIcon` classification table pins its coarse output, including `Makefile` remaining `other`. Attachment, chat, queue, and sidebar component suites exercise the migrated render paths; their accessibility output does not change because the glyphs remain decorative.
+
+## Consequences
+
+- Client packages use one filename parser and one detailed file-type table instead of importing or recreating feature-local logic.
+- A new suffix joins the detailed table only when an existing glyph truthfully represents it. If its link category differs from the current adapter, the change must also decide whether the 14px link appearance changes.
+- Code and configuration artwork preserves its embedded palette and does not accept the traditional `--dsh-file-type-icon-color` override.
+- The primitive owns no copy but does own the default file-type palette. Consumers continue to own accessible labels and surrounding text, and may replace the category color through `--dsh-file-type-icon-color`.
+- The detailed category names describe presentation, not MIME validation. A suffix is a display hint and does not establish file contents or trust.

+# Agent Note: 共享文件类型图标
+
+Status: implemented
+
+[English](2026-09-08-shared-file-type-icons.md) | 中文
+
+## 问题
+
+客户端功能插件只能通过 `@deepseek-ai/dsh-client-ui-primitives` 共享 React 组件，但文件卡片没有共享的文件类型呈现。`LinkIcon` 拥有唯一一份扩展名表，并有意把路径折叠为六种链接类别；附件卡片、已发送消息附件、排队文件和工作区文件行则统一使用一个通用文档图形。其中两个消费方还各自带着一份扩展名展示辅助函数。在其他位置增加精细文件图标，需要再复制一份扩展名表或让功能插件之间产生运行时 import。
+
+## 决策
+
+`ui-primitives` 统一拥有一套 Cordis-free 的文件分类与渲染 API。`fileExtension(path)` 对两种路径分隔符采用共享的 basename 与最终点号语义。`classifyFileType(path)` 不区分大小写，并返回闭合的 `FileType` 联合：传统的 `code`、`excel`、`folder`、`html`、`image`、`markdown`、`other`、`pdf`、`ppt`、`video`、`word` 类别，以及从所提供 `square-code-icons` 映射接入的细分 `CodeFileType` 集合。解析按完整文件名、文件名前缀、文件名后缀、可选项目上下文、扩展名的顺序执行。路径分类器返回 `folder` 之外的全部成员；调用方确认条目是目录时，通过 `FileTypeIcon` 的显式 `type` 覆盖指定目录。未知扩展名、无扩展名和末尾点号回退到 `other`，但共享表识别 `Dockerfile`、`Makefile`、`package.json`、`.gitignore`、`README`、`CHANGELOG` 等具名文件。
+
+`FileTypeIcon` 接受路径、共享 `IconProps`、可选的显式类型和可选的项目文件快照。传统文件类型把所提供的 28px 文档与文件夹轮廓渲染为 inline SVG。Excel、Markdown、PDF、PPT、Word 的前景标记围绕自身视觉中心缩放至 122%，其余带标记的传统图形使用 112%；文件底板与折角保持源图几何，通用文件不凭空增加中心标记。底板使用实色分类颜色，前景标记与普通折角使用白色，通用文件使用较深的灰色折角。CSS 通过静态设计 token 分配所提供的分类调色板：code/HTML/Markdown 使用 DeepSeek 蓝，Word 使用较浅的 DeepSeek 蓝，Excel 使用绿色，folder/PPT 使用两档琥珀色，PDF 使用红色，未知文件使用中性灰。image 与 video 通过组件本地变量共用所提供的紫色，因为设计平台没有匹配的紫色 token。调用方可通过 `--dsh-file-type-icon-color` 覆盖传统底板颜色。
+
+已识别的代码与配置文件把对应的 20px 方形图稿缩放到请求的图标尺寸。这些技术标记保留自身内嵌的多色填充，是普通 current-color 图标规则的明确例外。映射让 React 优先于 TypeScript/JavaScript、Angular 文件名后缀优先于基础扩展名，并按文件名识别 Docker/Node/Git/Make/CMake；只有可选项目快照包含内容带 `flutter:` 的 `pubspec.yaml` 时才选择 Flutter。Markdown 与 SVG 仍由传统 Markdown 和图片类别拥有。所有传统与技术 SVG 都是 `aria-hidden` 的，拥有文件身份的卡片、行或按钮提供无障碍名称。
+
+`LinkIcon` 委托 `classifyFileType` 做扩展名分类，再把精细结果折叠进原有链接词汇：code 与 HTML 使用 `code`，图片使用 `image`，PDF/Word/Excel/PPT 使用 `document`，Markdown、video 与未知文件使用 `other`。无扩展名文件在链接语境中仍是 `other`，因此[可点击链接决策](2026-09-04-web-clickable-link-styles.zh.md)定义的 14px 外观不变。
+
+附件上传卡片、已发送消息文件卡片、排队文件行和工作区文件行渲染 `FileTypeIcon`。两处元数据行使用 `fileExtension`，不再保留本地解析器；`.env` 这样的前导点 basename 会显示 `ENV`，无后缀或末尾点号则不显示扩展名 label。图片内容继续渲染为预览而不是文件类型图形，产物文件链接与 Markdown 文件提及继续使用 `LinkIcon`，因为它们属于链接表面。
+
+## 备选方案
+
+**所有文件表面都使用 `LinkIcon`。** 否决。它的六种类别和 14px outline 图形用于在文字尺寸下表达链接目标；28px 文件卡片有空间表达所提供的 HTML、Markdown、PDF、Word、Excel、PPT 与 video 身份。
+
+**在 `LinkIcon` 旁保留第二份扩展名表。** 否决。任一列表增长后，同一路径可能漂移到不同类别。一份精细表加一个显式的精细到链接适配，能同时保住两类消费方的语义。
+
+**把所提供的传统文件颜色直接写入每一条 SVG path。** 否决。传统 SVG 几何保持可复用，并遵守图标集的 `currentColor` 规则；组件样式表拥有默认分类调色板，渲染点只需一个 CSS 变量即可覆盖颜色，不需要重写 path 填充。技术图稿是例外，因为其内嵌的多色标记用于识别语言或工具，而不是装饰通用文件轮廓。
+
+**为了对称增加 archive、audio 与 data 类别。** 否决。提供的图稿与当前消费方都不需要这些图形。新增 `FileType` 成员必须有已发布的渲染点，以及在 28px slot 中仍可辨认的图稿。
+
+## 测试
+
+`ui-primitives` 测试覆盖不区分大小写的后缀、两种路径分隔符、前导点文件、无后缀与末尾点号、常见具名文件、未知回退、全部细分代码映射、规则优先级、Flutter 上下文、每一份技术 SVG、实例安全的渐变 id、`aria-hidden`、尺寸/class 转发、不同图稿、112% 与 122% 前景标记变换，以及不含 SVG 字面颜色的传统实色底板/对比标记层。样式表测试钉住每一项传统类别到颜色的映射、调用方覆盖变量与本地紫色值。既有 `LinkIcon` 分类表钉住它的粗粒度输出，包括 `Makefile` 仍为 `other`。附件、聊天、队列和侧边栏组件测试覆盖迁移后的渲染路径；由于图形仍是装饰性的，其无障碍输出不变。
+
+## 后果
+
+- 客户端包使用一个文件名解析器与一份精细文件类型表，不再 import 或重新实现功能包本地逻辑。
+- 新后缀只在已有图形能准确表达它时加入精细表。若它的链接类别与当前适配不同，这次改动还必须决定是否改变 14px 链接外观。
+- 代码与配置图稿保留内嵌调色板，不接受传统图形的 `--dsh-file-type-icon-color` 覆盖。
+- primitive 不拥有文案，但拥有默认文件类型调色板。消费方继续拥有无障碍 label 与周围文字，并可通过 `--dsh-file-type-icon-color` 替换分类颜色。
+- 精细类别名称描述展示意图，不是 MIME 校验。后缀只是展示提示，不能证明文件内容或可信度。
