+# Export 开发说明
+
+> 所属模块：Export Service（后端，负责人 yxx）。交付「多格式文档导出」：Markdown → HTML / PDF / DOCX 的完整生命周期与 function-plot 静态 SVG 渲染。契约对应 [第二阶段接口契约 §10](../contracts/第二阶段接口契约-开发版.md)。
+
+## 定位
+
+Export Service 把笔记或未保存的 Markdown 文本渲染为可下载的 HTML 文件。采用与 Benchmark 一致的「创建即返回 queued、后台 asyncio.Task 执行」的内存模型，产物带 24h 过期时间，过期后不可下载。导出是轮询式（无 SSE 事件流），客户端通过 `GET /api/exports/{job_id}` 轮询状态，完成后走 `GET /api/exports/{job_id}/file` 下载。

+
+## 接口
+
+| 方法 | 路径 | 用途 |
+| --- | --- | --- |
+| POST | `/api/exports` | 创建导出任务（202） |
+| GET | `/api/exports?status=&format=&limit=&offset=` | 分页获取任务 |
+| GET | `/api/exports/{job_id}` | 查询任务状态 |
+| GET | `/api/exports/{job_id}/file` | 下载已完成产物 |
+| POST | `/api/exports/{job_id}/cancel` | 取消任务 |
+
+`source.type` 支持 `note`（引用已建索引笔记）与 `markdown`（未保存预览，字段为 `source.markdown`，上限 200 000 字符）。`format` 支持 `html` / `pdf` / `docx` 三种，经 `service._EXPORTERS` 注册表按格式分发到对应导出器。
+
+## Markdown → Document AST
+
+解析用 [mistune](https://github.com/lepture/mistune) 的内置 `renderer="ast"`（非自写 `BaseRenderer`），因为 mistune 的行内渲染按字符串拼接、无法承载结构化子节点；ast renderer 直接给出带 `children`/`attrs`/`raw` 的 token 树，`_AstMapper` 只做 token → `DocumentNode` 的搬运，不掺入任何 HTML。插件启用 `table`、`math`、`url`、`task_lists`。
+
+fenced code 按语言分流：`mermaid` → `mermaid` 节点、`function_plot`/`functionplot` → `function_plot` 节点，其余 → `code_block`（`attributes.language`）。`node_id` 按遍历顺序 `node_{seq:03d}` 生成，仅渲染内部使用，无需跨请求稳定。
+
+## HtmlExporter
+
+递归渲染 Document AST 为完整 HTML5 文档（`<!doctype html>` + `<head>` 内嵌基础 CSS + `<body>`），标题/正文/元信息文本一律 `html.escape`。`function_plot` 经 `FunctionPlotStaticRenderer` 解析为静态 SVG 内嵌（解析/渲染失败或超限时回退 `<pre class="function-plot">` 占位并记 warning），`mermaid` 无法静态表达，渲染为占位 `<pre class="mermaid">` 并记 warning，均不静默丢失；`code_theme` 仅作为代码容器 class，不引入 JS 高亮库。无法表示的节点统一 `warnings.append(...)` 跳过。
+
+## StaticRenderer 内部契约（§10.4）
+
+函数图像与 Mermaid 的静态渲染统一收敛到 `app/plot/renderer.py`：
+
+- `StaticRenderRequest`（`kind` / `source` / `source_hash` / `theme` / `width` / `height`）是统一的渲染请求载体，`source_hash` 供缓存/去重，`theme` 供主题化渲染。
+- `StaticRenderer` Protocol 定义 `render(request) -> StaticRenderResult`，导出器只面向协议，不直接调用 `render_svg`。
+- `FunctionPlotStaticRenderer` 委托 `parse_source` 解析 + `render_svg` 输出内嵌 SVG；`parse` 与 `render_plot` 拆开，供导出器在渲染前先拿 `node_count` 做文档级累计复杂度预算。
+- `MermaidStaticRenderer` 后端无 Mermaid 渲染能力，返回空占位结果并记 warning，交由前端渲染。
+
+## PDF / DOCX 导出器（v1 文本优先）
+
+`PdfExporter`（reportlab platypus）与 `DocxExporter`（python-docx）实现与 HtmlExporter 一致的同步 `render(document, options) -> ExportResult` + 异步 `export`。v1 为文本优先，覆盖标题/段落/行内强调与链接/列表/引用/表格/代码块/数学文本；`mermaid` 保留源码占位并记 warning。`function_plot` 在 PDF 中已内嵌为矢量图，在 DOCX 中仍保留源码占位并记 warning（DOCX 内嵌需栅格化，本轮范围外）。
+
+- PDF 中文字体用 reportlab 内置 `STSong-Light` CID 字体，无外部字体依赖；CID 字体无独立 bold/italic 字重，行内强调退化为普通文本（内容不丢、样式简化），标题靠字号区分层级。
+- PDF 的 `function_plot` 经 `render_reportlab` 消费 `compute_geometry` 的共享几何，产出矢量 `Drawing`（网格/坐标轴 `Line`、曲线 `PolyLine`、刻度/标签 `String`，ylabel 用 `Group` 旋转），再按页面内容宽缩放追加到 story，与 HTML 的 SVG 视觉一致；解析/渲染失败或超预算时回退源码占位并记 warning，单图失败不阻断整篇。
+- DOCX 通过 Normal 样式挂载 `w:eastAsia=宋体` 保证中文显示，bold/italic 由 Word 原生渲染；链接写入可点击的 `w:hyperlink` run。
+- 扩展名/MIME：html→`.html`/`text/html`，pdf→`.pdf`/`application/pdf`，docx→`.docx`/`application/vnd.openxmlformats-officedocument.wordprocessingml.document`；路由 `FileResponse` 按 `mime_type` + `file_name` 通用化，无需改路由。
+
+## 运行生命周期
+
+`queued → running → completed | failed | cancelled`。
+
+- 创建时校验：`note` 源不存在 → `EXPORT_SOURCE_NOT_FOUND`（404）；`markdown` 源为空或超上限 → `EXPORT_OPTIONS_INVALID`。
+- 内存注册表上限 `MAX_JOBS=100`，超限只淘汰终态任务；满容量且全为活动任务时返回 `EXPORT_CAPACITY_EXCEEDED`（429）。
+- 后台渲染在解析前后各让出一次执行权，使「创建后立即取消」的 queued 任务能及时进入 cancelled。
+- 失败只向公开响应暴露项目错误码与安全消息，详细异常进入日志。
+
+## 产物生命周期
+
+产物写入 `settings.exports_path`（默认 `backend/data/exports/`，可通过 `APP_EXPORTS_PATH` 覆盖，已加入 `.gitignore`），文件名为 `{job_id}{ext}`（`ext` 由格式决定），下载 `Content-Disposition` 用 `_safe_download_name` 清洗标题得到。`ExportFile` 记录 `sha256`、`size` 与 `expires_at`（`completed_at + 24h`），过期返回 `EXPORT_FILE_EXPIRED`（410）。
+
+## 资源上限
+
+为防止超大输入或海量函数图像耗尽内存/线程，导出链路内置以下上限：
+
+- 输入源（`note` 与 `markdown`）统一限制 `MAX_MARKDOWN_CHARS = 200_000` 字符，超限返回 `EXPORT_OPTIONS_INVALID`。
+- 单个 `function-plot` 图块最多 16 条表达式，超限整块回退占位并记结构化诊断 `FUNCTION_PLOT_TOO_MANY_EXPRESSIONS`。
+- 单篇文档最多 16 个函数图像，超出部分回退占位并记 warning。
+- 单篇文档累计函数图像 AST 节点预算 `_MAX_TOTAL_PLOT_NODES = 8000`，超出部分回退占位并记 warning，防止多图块 × 多表达式 × 深表达式组合在采样求值时长时间占满 CPU。
+- 并发渲染上限 `MAX_CONCURRENT_RENDERS = 2`，解析/渲染是 CPU 密集工作，超出限额的任务在内存中排队等待渲染槽位，避免大量任务同时占满工作线程与内存。
+- 最终产物大小上限 `MAX_EXPORT_BYTES = 20 MB`，超限任务标记 failed 并返回 `EXPORT_OUTPUT_TOO_LARGE`。
+
+## 错误码
+
+错误分两类：**同步错误**在创建/查询请求的 HTTP 响应里直接返回对应状态码；**异步任务错误**在创建时已返回 `202`，后续轮询 `GET /api/exports/{job_id}` 仍返回 `200`，错误通过任务状态与 `error_code` 字段暴露，**不映射 HTTP 状态码**。
+
+同步错误：

+EXPORT_UNSUPPORTED_CONTENT   422（预留）

+EXPORT_FILE_EXPIRED          410
+EXPORT_CAPACITY_EXCEEDED     429

+
+异步任务错误（轮询返回 `200`，字段形如 `{"status": "failed", "error_code": "..."}`）：
+
+```text
+EXPORT_RENDER_FAILED
+EXPORT_OUTPUT_TOO_LARGE
+```
+
+## 测试
+
+```powershell
+cd backend
+uv run pytest -q
+```
+
+`tests/test_export.py` 覆盖 Markdown 解析（标题/行内/列表/代码分流/表格/数学）、HTML 渲染（标签 + 转义 + warning）、Service 端到端（note 源与 markdown 源、PDF/DOCX 魔法字节与 CJK 字体、引用块正文与嵌套列表顺序等结构内容回归、排队任务取消、未知 note、取消、list/get、过期 410）与 `ExportSource` 契约校验。`tests/test_plot.py` 覆盖表达式解析/求值、SVG 渲染、共享几何 `compute_geometry`、`render_reportlab` 矢量 Drawing（Line/PolyLine/String/Group、CJK 字体、y 翻转、缩放）与 `StaticRenderer` 契约（函数图像渲染、Mermaid 占位）。
+
+## 范围外（后续 PR）
+
+- Mermaid 静态渲染（后端无渲染能力，HTML/PDF/DOCX 均保留源码占位）。
+- DOCX 内嵌函数图像（需栅格化为 PNG，本轮范围外，仅 PDF 内嵌矢量图）。
+- 函数图像交互预览与缩放（前端 JS Renderer 负责，后端仅提供静态 SVG）。
+- 代码语法高亮（当前仅 CSS class 占位）。
