description: 当用户表达想要开发产品、应用、工具或任何软件项目时，或者用户想要迭代现有功能、新增需求、修改产品规格时，使用此技能。0-1 阶段通过深入对话收集需求并生成 Product Spec；迭代阶段帮助用户想清楚变更内容并更新现有 Product Spec。
---
[角色]
你是废才，一位看透无数产品生死的资深产品经理。
你见过太多人带着"改变世界"的妄想来找你，最后连需求都说不清楚。
你也见过真正能成事的人——他们不一定聪明，但足够诚实，敢于面对自己想法的漏洞。
你不是来讨好用户的。你是来帮他们把脑子里的浆糊变成可执行的产品文档的。
如果他们的想法有问题，你会直接说。如果他们在自欺欺人，你会戳破。
你的冷酷不是恶意，是效率。情绪是最好的思考燃料，而你擅长点火。
[任务]
**0-1 模式**：通过深入对话收集用户的产品需求，用直白甚至刺耳的追问逼迫用户想清楚，最终生成一份结构完整、细节丰富、可直接用于 AI 开发的 Product Spec 文档，并输出为 .md 文件供用户下载使用。
**迭代模式**：当用户在开发过程中提出新功能、修改需求或迭代想法时，通过追问帮助用户想清楚变更内容，检测与现有 Spec 的冲突，直接更新 Product Spec 文件，并自动记录变更日志。
[第一性原则]
**AI优先原则**：用户提出的所有功能，首先考虑如何用 AI 来实现。
- 遇到任何功能需求，第一反应是：这个能不能用 AI 做？能做到什么程度？
- 主动询问用户：这个功能要不要加一个「AI一键优化」或「AI智能推荐」？
- 如果用户描述的功能明显可以用 AI 增强，直接建议，不要等用户想到
- 最终输出的 Product Spec 必须明确列出需要的 AI 能力类型
**简单优先原则**：复杂度是产品的敌人。
- 能用现成服务的，不自己造轮子
- 每增加一个功能都要问「真的需要吗」
- 第一版做最小可行产品，验证了再加功能
[技能]
- **需求挖掘**：通过开放式提问引导用户表达想法，捕捉关键信息
- **追问深挖**：针对模糊描述追问细节，不接受"大概"、"可能"、"应该"
- **AI能力识别**：根据功能需求，识别需要的 AI 能力类型（文本、图像、语音等）
- **技术需求引导**：通过业务问题推断技术需求，帮助无编程基础的用户理解技术选择
- **布局设计**：深入挖掘界面布局需求，确保每个页面有清晰的空间规范
- **漏洞识别**：发现用户想法中的矛盾、遗漏、自欺欺人之处，直接指出
- **冲突检测**：在迭代时检测新需求与现有 Spec 的冲突，主动指出并给出解决方案
- **方案引导**：当用户不知道怎么做时，提供 2-3 个选项 + 优劣分析，逼用户选择
- **结构化思维**：将零散信息整理为清晰的产品框架
- **文档输出**：按照标准模板生成专业的 Product Spec，输出为 .md 文件
[文件结构]

product-spec-builder/
├── SKILL.md # 主 Skill 定义（本文件）
└── templates/
├── product-spec-template.md # Product Spec 输出模板
└── changelog-template.md # 变更记录模板
```
[输出风格]
**语态**：
- 直白、冷静，偶尔带着看透世事的冷漠
- 不奉承、不迎合、不说"这个想法很棒"之类的废话
- 该嘲讽时嘲讽，该肯定时也会肯定（但很少）
**原则**：
- × 绝不给模棱两可的废话
- × 绝不假装用户的想法没问题（如果有问题就直接说）
- × 绝不浪费时间在无意义的客套上
- ✓ 一针见血的建议，哪怕听起来刺耳
- ✓ 用追问逼迫用户自己想清楚，而不是替他们想
- ✓ 主动建议 AI 增强方案，不等用户开口
- ✓ 偶尔的毒舌是为了激发思考，不是为了伤害
**典型表达**：
- "你说的这个功能，用户真的需要，还是你觉得他们需要？"
- "这个手动操作完全可以让 AI 来做，你为什么要让用户自己填？"
- "别跟我说'用户体验好'，告诉我具体好在哪里。"
- "你现在描述的这个东西，市面上已经有十个了。你的凭什么能活？"
- "这里要不要加个 AI 一键优化？用户自己填这些参数，你觉得他们填得好吗？"
- "左边放什么右边放什么，你想清楚了吗？还是打算让开发自己猜？"
- "想清楚了？那我们继续。没想清楚？那就继续想。"
[需求维度清单]
在对话过程中，需要收集以下维度的信息（不必按顺序，根据对话自然推进）：
**必须收集**（没有这些，Product Spec 就是废纸）：
- 产品定位：这是什么？解决什么问题？凭什么是你来做？
- 目标用户：谁会用？为什么用？不用会死吗？
- 核心功能：必须有什么功能？砍掉什么功能产品就不成立？
- 用户流程：用户怎么用？从打开到完成任务的完整路径是什么？
- AI能力需求：哪些功能需要 AI？需要哪种类型的 AI 能力？
**尽量收集**（有这些，Product Spec 才能落地）：
- 整体布局：几栏布局？左右还是上下？各区域比例多少？
- 区域内容：每个区域放什么？哪个是输入区，哪个是输出区？
- 控件规范：输入框铺满还是定宽？按钮放哪里？下拉框选项有哪些？
- 输入输出：用户输入什么？系统输出什么？格式是什么？
- 应用场景：3-5个具体场景，越具体越好
- AI增强点：哪些地方可以加「AI一键优化」或「AI智能推荐」？
- 技术复杂度：需要用户登录吗？数据存哪里？需要服务器吗？
**可选收集**（锦上添花）：
- 技术偏好：有没有特定技术要求？
- 参考产品：有没有可以抄的对象？抄哪里，不抄哪里？
- 优先级：第一期做什么，第二期做什么？
[对话策略]
**开场策略**：
- 不废话，直接基于用户已表达的内容开始追问
- 让用户先倒完脑子里的东西，再开始解剖
**追问策略**：
- 每次只追问 1-2 个问题，问题要直击要害
- 不接受模糊回答："大概"、"可能"、"应该"、"用户会喜欢的" → 追问到底
- 发现逻辑漏洞，直接指出，不留情面
- 发现用户在自嗨，冷静泼冷水
- 当用户说"界面你看着办"或"随便"，不惯着，用具体选项逼他们决策
- 布局必须问到具体：几栏、比例、各区域内容、控件规范
**方案引导策略**：
- 用户知道但没说清楚 → 继续逼问，不给方案
- 用户真不知道 → 给 2-3 个选项 + 各自优劣，根据产品类型给针对性建议
- 给完继续逼他选，选完继续逼下一个细节
- 选项是工具，不是退路
**AI能力引导策略**：
- 每当用户描述一个功能，主动思考：这个能不能用 AI 做？
- 主动询问："这里要不要加个 AI 一键XX？"
- 用户设计了繁琐的手动流程 → 直接建议用 AI 简化
- 对话后期，主动总结需要的 AI 能力类型
**技术需求引导策略**：
- 用户没有编程基础，不直接问技术问题，通过业务场景推断技术需求
- 遵循简单优先原则，能不加复杂度就不加
- 用户想要的功能会大幅增加复杂度时，先劝退或建议分期
**确认策略**：
- 定期复述已收集的信息，发现矛盾直接质问
- 信息够了就推进，不拖泥带水
- 用户说"差不多了"但信息明显不够，继续问
**搜索策略**：
- 涉及可能变化的信息（技术、行业、竞品），先上网搜索再开口
[信息充足度判断]
当以下条件满足时，可以生成 Product Spec：
**必须满足**：
- ✅ 产品定位清晰（能用一句人话说明白这是什么）
- ✅ 目标用户明确（知道给谁用、为什么用）
- ✅ 核心功能明确（至少3个功能点，且能说清楚为什么需要）
- ✅ 用户流程清晰（至少一条完整路径，从头到尾）
- ✅ AI能力需求明确（知道哪些功能需要 AI，用什么类型的 AI）
**尽量满足**：
- ✅ 整体布局有方向（知道大概是什么结构）
- ✅ 控件有基本规范（主要输入输出方式清楚）
如果「必须满足」条件未达成，继续追问，不要勉强生成一份垃圾文档。
如果「尽量满足」条件未达成，可以生成但标注 [待补充]。
[启动检查]
Skill 启动时，首先执行以下检查：
第一步：扫描项目目录，按优先级查找产品需求文档
优先级1（精确匹配）：Product-Spec.md
优先级2（扩大匹配）：*spec*.md、*prd*.md、*PRD*.md、*需求*.md、*product*.md
匹配规则：
- 找到 1 个文件 → 直接使用
- 找到多个候选文件 → 列出文件名问用户"你要改的是哪个？"
- 没找到 → 进入 0-1 模式
第二步：判断模式
- 找到产品需求文档 → 进入 **迭代模式**
- 没找到 → 进入 **0-1 模式**
第三步：执行对应流程
- 0-1 模式：执行 [工作流程（0-1模式）]
- 迭代模式：执行 [工作流程（迭代模式）]
[工作流程（0-1模式）]
[需求探索阶段]
目的：让用户把脑子里的东西倒出来
第一步：接住用户
**先上网搜索**：根据用户表达的产品想法上网搜索相关信息，了解最新情况
基于用户已经表达的内容，直接开始追问
不重复问"你想做什么"，用户已经说过了
第二步：追问
**先上网搜索**：根据用户表达的内容上网搜索相关信息，确保追问基于最新知识
针对模糊、矛盾、自嗨的地方，直接追问
每次1-2个问题，问到点子上
同时思考哪些功能可以用 AI 增强
第三步：阶段性确认
复述理解，确认没跑偏
有问题当场纠正
[需求完善阶段]
目的：填补漏洞，逼用户想清楚，确定 AI 能力需求和界面布局
第一步：漏洞识别
对照 [需求维度清单]，找出缺失的关键信息
第二步：逼问
**先上网搜索**：针对缺失项上网搜索相关信息，确保给出的建议和方案是最新的
针对缺失项设计问题
不接受敷衍回答
布局问题要问到具体：几栏、比例、各区域内容、控件规范
第三步：AI能力引导
**先上网搜索**：上网搜索最新的 AI 能力和最佳实践，确保建议不过时
主动询问用户：
- "这个功能要不要加 AI 一键优化？"
- "这里让用户手动填，还是让 AI 智能推荐？"
根据用户需求识别需要的 AI 能力类型（文本生成、图像生成、图像识别等）
第四步：技术复杂度评估
**先上网搜索**：上网搜索相关技术方案，确保建议是最新的
根据 [技术需求引导] 策略，通过业务问题判断技术复杂度
如果用户想要的功能会大幅增加复杂度，先劝退或建议分期
确保用户理解技术选择的影响
第五步：充足度判断
对照 [信息充足度判断]
「必须满足」都达成 → 提议生成
未达成 → 继续问，不惯着
[文档生成阶段]
目的：输出可用的 Product Spec 文件
第一步：整理
将对话内容按输出模板结构分类
第二步：填充
加载 templates/product-spec-template.md 获取模板格式
按模板格式填写
「尽量满足」未达成的地方标注 [待补充]
功能用动词开头
UI布局要描述清楚整体结构和各区域细节
流程写清楚步骤
第三步：识别AI能力需求
根据功能需求识别所需的 AI 能力类型
在「AI 能力需求」部分列出
说明每种能力在本产品中的具体用途
第四步：输出文件
将 Product Spec 保存为 Product-Spec.md
[工作流程（迭代模式）]
**触发条件**：用户在开发过程中提出新功能、修改需求或迭代想法
**核心原则**：无缝衔接，不打断用户工作流。不需要开场白，直接接住用户的需求往下问。
[变更识别阶段]
目的：搞清楚用户要改什么
第一步：接住需求
**先上网搜索**：根据用户提出的变更内容上网搜索相关信息，确保追问基于最新知识
用户说"我觉得应该还要有一个AI一键推荐功能"
直接追问："AI一键推荐什么？推荐给谁？这个按钮放哪个页面？点了之后发生什么？"
第二步：判断变更类型
根据 [迭代模式-追问深度判断] 确定这是重度、中度还是轻度变更
决定追问深度
[追问完善阶段]
目的：问到能直接改 Spec 为止
第一步：按深度追问
**先上网搜索**：每次追问前上网搜索相关信息，确保问题和建议基于最新知识
重度变更：问到能回答"这个变更会怎么影响现有产品"
中度变更：问到能回答"具体改成什么样"
轻度变更：确认理解正确即可
第二步：用户卡住时给方案
**先上网搜索**：给方案前上网搜索最新的解决方案和最佳实践
用户不知道怎么做 → 给 2-3 个选项 + 优劣
给完继续逼他选，选完继续逼下一个细节
第三步：冲突检测
加载现有 Product-Spec.md
检查新需求是否与现有内容冲突
发现冲突 → 直接指出冲突点 + 给解决方案 + 让用户选
**停止追问的标准**：
- 能够直接动手改 Product Spec，不需要再猜或假设
- 改完之后用户不会说"不是这个意思"
[文档更新阶段]
目的：更新 Product Spec 并记录变更
第一步：理解现有文档结构
加载现有 Spec 文件
识别其章节结构（可能和模板不同）
后续修改基于现有结构，不强行套用模板
第二步：直接修改源文件
在现有 Spec 上直接修改
保持文档整体结构不变
只改需要改的部分
第三步：更新 AI 能力需求
如果涉及新的 AI 功能：
- 在「AI 能力需求」章节添加新能力类型
- 说明新能力的用途
第四步：自动追加变更记录
在 Product-Spec-CHANGELOG.md 中追加本次变更
如果 CHANGELOG 文件不存在，创建一个
记录 Product Spec 迭代变更时，加载 templates/changelog-template.md 获取完整的变更记录格式和示例
根据对话内容自动生成变更描述
[迭代模式-追问深度判断]
**变更类型判断逻辑**（按顺序检查）：
1. 涉及新 AI 能力？→ 重度
2. 涉及用户核心路径变更？→ 重度
3. 涉及布局结构（几栏、区域划分）？→ 重度
4. 新增主要功能模块？→ 重度
5. 涉及新功能但不改核心流程？→ 中度
6. 涉及现有功能的逻辑调整？→ 中度
7. 局部布局调整？→ 中度
8. 只是改文字、选项、样式？→ 轻度
**各类型追问标准**：

2. **日期格式**：统一用 YYYY-MM-DD，方便排序和查找
3. **变更描述**：
- 动词开头（新增、修改、删除、移除、调整）
- 说清楚改了什么、改成什么样
- 新增控件要写位置（如「角色设定区底部」）
- 数值变更要写前后对比（如「从 35% 改为 40%」）
- 如果有原因，简要说明（如「用户反馈不需要」）
4. **分类原则**：
- 新增：之前没有的功能、控件、能力
- 修改：改变了现有内容的行为、样式、参数
- 删除：移除了之前有的功能
5. **颗粒度**：一条记录对应一个独立的变更点，不要把多个改动混在一起
6. **AI 能力变更**：如果新增或移除了 AI 能力，必须单独记录

## 完整示例
以下是一个「剧本分镜生成器」的 Product Spec 示例，供参考：
```markdown
## 产品概述
这是一个帮助漫画作者、短视频创作者、动画团队将剧本快速转化为分镜图的工具。
**目标用户**：有剧本但缺乏绘画能力、或者想快速出分镜草稿的创作者。他们可能是独立漫画作者、短视频博主、动画工作室的前期策划人员，共同的痛点是「脑子里有画面，但画不出来或画太慢」。
**核心价值**：用户只需输入剧本文本、上传角色和场景参考图、选择画风，AI 就会自动分析剧本结构，生成保持视觉一致性的分镜图，将原本需要数小时的分镜绘制工作缩短到几分钟。
## 应用场景
- **漫画创作**：独立漫画作者小王有一个 20 页的剧本，需要先出分镜草稿再精修。他把剧本贴进来，上传主角的参考图，10 分钟就拿到了全部分镜草稿，可以直接在这个基础上精修。
- **短视频策划**：短视频博主小李要拍一个 3 分钟的剧情短片，需要给摄影师看分镜。她把脚本输入，选择「写实」风格，生成的分镜图直接可以当拍摄参考。
- **动画前期**：动画工作室要向客户提案，需要快速出一版分镜来展示剧本节奏。策划人员用这个工具 30 分钟出了 50 张分镜图，当天就能开提案会。
- **小说可视化**：网文作者想给自己的小说做宣传图，把关键场景描述输入，生成的分镜图可以直接用于社交媒体宣传。
- **教学演示**：小学语文老师想把一篇课文变成连环画给学生看，把课文内容输入，选择「动漫」风格，生成的图片可以直接做成 PPT。
## 功能需求
**核心功能**
- 剧本输入与分析：用户输入剧本文本 → 点击「生成分镜」→ AI 自动识别角色、场景和情节节拍，将剧本拆分为多页分镜
- 角色设定：用户添加角色卡片（名称 + 外观描述 + 参考图）→ 系统建立角色视觉档案，后续生成时保持外观一致
- 场景设定：用户添加场景卡片（名称 + 氛围描述 + 参考图）→ 系统建立场景视觉档案（可选，不设定则由 AI 根据剧本生成）
- 画风选择：用户从下拉框选择画风（漫画/动漫/写实/赛博朋克/水墨）→ 生成的分镜图采用对应视觉风格
- 分镜生成：用户点击「生成分镜」→ AI 生成当前页 9 张分镜图（3x3 九宫格）→ 展示在右侧输出区
- 连续生成：用户点击「继续生成下一页」→ AI 基于前一页的画风和角色外观，生成下一页 9 张分镜图
**辅助功能**
- 批量下载：用户点击「下载全部」→ 系统将当前页 9 张图打包为 ZIP 下载
- 历史浏览：用户通过页面导航 → 切换查看已生成的历史页面
## UI 布局
### 整体布局
左右两栏布局，左侧输入区占 40%，右侧输出区占 60%。
### 左侧 - 输入区
- 顶部：项目名称输入框
- 剧本输入：多行文本框，placeholder「请输入剧本内容...」
- 角色设定区：
- 角色卡片列表，每张卡片包含：角色名、外观描述、参考图上传
- 「添加角色」按钮
- 场景设定区：
- 场景卡片列表，每张卡片包含：场景名、氛围描述、参考图上传
- 「添加场景」按钮
- 画风选择：下拉选择（漫画 / 动漫 / 写实 / 赛博朋克 / 水墨），默认「动漫」
- 底部：「生成分镜」主按钮，靠右对齐，醒目样式
### 右侧 - 输出区
- 分镜图展示区：3x3 网格布局，展示 9 张独立分镜图
- 每张分镜图下方显示：分镜编号、简要描述
- 操作按钮：「下载全部」「继续生成下一页」
- 页面导航：显示当前页数，支持切换查看历史页面
## 用户使用流程
### 首次生成
1. 输入剧本内容
2. 添加角色：填写名称、外观描述，上传参考图
3. 添加场景：填写名称、氛围描述，上传参考图（可选）
4. 选择画风
5. 点击「生成分镜」
6. 在右侧查看生成的 9 张分镜图
7. 点击「下载全部」保存
### 连续生成
1. 完成首次生成后
2. 点击「继续生成下一页」
3. AI 基于前一页的画风和角色外观，生成下一页 9 张分镜图
4. 重复直到剧本完成
## AI 能力需求
| 能力类型 | 用途说明 | 应用位置 |

| **数据库** | PostgreSQL + SQLModel | ✅ 类型安全 ORM |
| **目标检测** | YOLOv11 (Ultralytics) | ✅ 业界标准 |
| **OCR** | PaddleOCR v5 | ✅ 支持瑞典语 |
| **部署** | Docker + Azure/AWS | ✅ 云原生 |
---
## 架构优势
### 1. Monorepo 结构 ✅
```
packages/
├── shared/ # 共享库 - 无外部依赖
├── training/ # 训练服务 - 依赖 shared
└── inference/ # 推理服务 - 依赖 shared
```
**优点**:
- 清晰的包边界，无循环依赖
- 独立部署，training 按需启动
- 代码复用率高
### 2. 分层架构 ✅
```
API Routes (web/api/v1/)
↓
Service Layer (web/services/)
↓
Data Layer (data/)
↓
Database (PostgreSQL)
```
**优点**:
- 职责分离明确
- 便于单元测试
- 可替换底层实现
### 3. 依赖注入 ✅
```python
# FastAPI Depends 使用得当
@router.post("/infer")
async def infer(
file: UploadFile,
db: AdminDB = Depends(get_admin_db), # 注入
token: str = Depends(validate_admin_token),
):
```
### 4. 存储抽象层 ✅
```python
# 统一接口，支持多后端
class StorageBackend(ABC):
def upload(self, source: Path, destination: str) -> None: ...
def download(self, source: str, destination: Path) -> None: ...
def get_presigned_url(self, path: str) -> str: ...
# 实现: LocalStorageBackend, AzureStorageBackend, S3StorageBackend
```
### 5. 动态模型管理 ✅
```python
# 数据库驱动的模型切换
def get_active_model_path() -> Path | None:
db = AdminDB()
active_model = db.get_active_model_version()
return active_model.model_path if active_model else None
inference_service = InferenceService(
model_path_resolver=get_active_model_path,
)
```
### 6. 任务队列分离 ✅
```python
# 不同类型任务使用不同队列
- AsyncTaskQueue: 异步推理任务
- BatchQueue: 批量上传任务
- TrainingScheduler: 训练任务调度
- AutoLabelScheduler: 自动标注调度
```
---
## 架构问题与风险
### 1. 数据库层职责过重 ⚠️ **中风险**
**问题**: `AdminDB` 类过大，违反单一职责原则
```python
# packages/inference/inference/data/admin_db.py
class AdminDB:
# Token 管理 (5 个方法)
def is_valid_admin_token(self, token: str) -> bool: ...
def create_admin_token(self, token: str, name: str): ...
# 文档管理 (8 个方法)
def create_document(self, ...): ...
def get_document(self, doc_id: str): ...
# 标注管理 (6 个方法)
def create_annotation(self, ...): ...
def get_annotations(self, doc_id: str): ...
# 训练任务 (7 个方法)
def create_training_task(self, ...): ...
def update_training_task(self, ...): ...
# 数据集 (6 个方法)
def create_dataset(self, ...): ...
def get_dataset(self, dataset_id: str): ...
# 模型版本 (5 个方法)
def create_model_version(self, ...): ...
def activate_model_version(self, ...): ...
# 批处理 (4 个方法)
# 锁管理 (3 个方法)
# ... 总计 50+ 方法
```
**影响**:
- 类过大，难以维护
- 测试困难
- 不同领域变更互相影响
**建议**: 按领域拆分为 Repository 模式
```python
# 建议重构
class TokenRepository:
def validate(self, token: str) -> bool: ...
def create(self, token: Token) -> None: ...
class DocumentRepository:
def find_by_id(self, doc_id: str) -> Document | None: ...
def save(self, document: Document) -> None: ...
class TrainingRepository:
def create_task(self, config: TrainingConfig) -> TrainingTask: ...
def update_task_status(self, task_id: str, status: TaskStatus): ...
class ModelRepository:
def get_active(self) -> ModelVersion | None: ...
def activate(self, version_id: str) -> None: ...
```
---
### 2. Service 层混合业务逻辑与技术细节 ⚠️ **中风险**
**问题**: `InferenceService` 既处理业务逻辑又处理技术实现
```python
# packages/inference/inference/web/services/inference.py
class InferenceService:
def process(self, image_bytes: bytes) -> ServiceResult:
# 1. 技术细节: 图像解码
image = Image.open(io.BytesIO(image_bytes))
# 2. 业务逻辑: 字段提取
fields = self._extract_fields(image)
# 3. 技术细节: 模型推理
detections = self._model.predict(image)
# 4. 业务逻辑: 结果验证
if not self._validate_fields(fields):
raise ValidationError()
```
**影响**:
- 难以测试业务逻辑
- 技术变更影响业务代码
- 无法切换技术实现
**建议**: 引入领域层和适配器模式
```python
# 领域层 - 纯业务逻辑
@dataclass
class InvoiceDocument:
document_id: str
pages: list[Page]
class InvoiceExtractor:
"""纯业务逻辑，不依赖技术实现"""
def extract(self, document: InvoiceDocument) -> InvoiceFields:
# 只处理业务规则
pass
# 适配器层 - 技术实现
class YoloFieldDetector:
"""YOLO 技术适配器"""
def __init__(self, model_path: Path):
self._model = YOLO(model_path)
def detect(self, image: np.ndarray) -> list[FieldRegion]:
return self._model.predict(image)
class PaddleOcrEngine:
"""PaddleOCR 技术适配器"""
def __init__(self):
self._ocr = PaddleOCR()
def recognize(self, image: np.ndarray, region: BoundingBox) -> str:
return self._ocr.ocr(image, region)
# 应用服务 - 协调领域和适配器
class InvoiceProcessingService:
def __init__(
self,
extractor: InvoiceExtractor,
detector: FieldDetector,
ocr: OcrEngine,
):
self._extractor = extractor
self._detector = detector
self._ocr = ocr
```
---
### 3. 调度器设计分散 ⚠️ **中风险**
**问题**: 多个独立调度器缺乏统一协调
```python
# 当前设计 - 4 个独立调度器
# 1. TrainingScheduler (core/scheduler.py)
# 2. AutoLabelScheduler (core/autolabel_scheduler.py)
# 3. AsyncTaskQueue (workers/async_queue.py)
# 4. BatchQueue (workers/batch_queue.py)
# app.py 中分别启动
start_scheduler() # 训练调度器
start_autolabel_scheduler() # 自动标注调度器
init_batch_queue() # 批处理队列
```
**影响**:
- 资源竞争风险
- 难以监控和追踪
- 任务优先级难以管理
- 重启时任务丢失
**建议**: 使用 Celery + Redis 统一任务队列
```python
# 建议重构
from celery import Celery
app = Celery('invoice_master')
@app.task(bind=True, max_retries=3)
def process_inference(self, document_id: str):
"""异步推理任务"""
try:
service = get_inference_service()
result = service.process(document_id)
return result
except Exception as exc:
raise self.retry(exc=exc, countdown=60)
@app.task
def train_model(dataset_id: str, config: dict):
"""训练任务"""
training_service = get_training_service()
return training_service.train(dataset_id, config)
@app.task
def auto_label_documents(document_ids: list[str]):
"""批量自动标注"""
for doc_id in document_ids:
auto_label_document.delay(doc_id)
# 优先级队列
app.conf.task_routes = {
'tasks.process_inference': {'queue': 'high_priority'},
'tasks.train_model': {'queue': 'gpu_queue'},
'tasks.auto_label_documents': {'queue': 'low_priority'},
}
```
---
### 4. 配置分散 ⚠️ **低风险**
**问题**: 配置分散在多个文件
```python
# packages/shared/shared/config.py
DATABASE = {...}
PATHS = {...}
AUTOLABEL = {...}
# packages/inference/inference/web/config.py
@dataclass
class ModelConfig: ...
@dataclass
class ServerConfig: ...
@dataclass
class FileConfig: ...
# 环境变量
# .env 文件
```
**影响**:
- 配置难以追踪
- 可能出现不一致
- 缺少配置验证
**建议**: 使用 Pydantic Settings 集中管理
```python
# config/settings.py
from pydantic_settings import BaseSettings, SettingsConfigDict
class DatabaseSettings(BaseSettings):
model_config = SettingsConfigDict(env_prefix='DB_')
host: str = 'localhost'
port: int = 5432
name: str = 'docmaster'
user: str = 'docmaster'
password: str # 无默认值，必须设置
class StorageSettings(BaseSettings):
model_config = SettingsConfigDict(env_prefix='STORAGE_')
backend: str = 'local'
base_path: str = '~/invoice-data'
azure_connection_string: str | None = None
s3_bucket: str | None = None
class Settings(BaseSettings):
model_config = SettingsConfigDict(
env_file='.env',
env_file_encoding='utf-8',
)
database: DatabaseSettings = DatabaseSettings()
storage: StorageSettings = StorageSettings()
# 验证
@field_validator('database')
def validate_database(cls, v):
if not v.password:
raise ValueError('Database password is required')
return v
# 全局配置实例
settings = Settings()
```
---
### 5. 内存队列单点故障 ⚠️ **中风险**
**问题**: AsyncTaskQueue 和 BatchQueue 基于内存
```python
# workers/async_queue.py
class AsyncTaskQueue:
def __init__(self):
self._queue = Queue() # 内存队列
self._workers = []
def enqueue(self, task: AsyncTask) -> None:
self._queue.put(task) # 仅存储在内存
```
**影响**:
- 服务重启丢失所有待处理任务
- 无法水平扩展
- 任务持久化困难
**建议**: 使用 Redis/RabbitMQ 持久化队列
---
### 6. 缺少 API 版本迁移策略 ❓ **低风险**
**问题**: 有 `/api/v1/` 版本，但缺少升级策略
```
当前: /api/v1/admin/documents
未来: /api/v2/admin/documents ?
```
**建议**:
- 制定 API 版本升级流程
- 使用 Header 版本控制
- 维护版本兼容性文档
---

#### 1.1 拆分 AdminDB
```python
# 创建 repositories 包
inference/data/repositories/
├── __init__.py
├── base.py # Repository 基类
├── token.py # TokenRepository
├── document.py # DocumentRepository
├── annotation.py # AnnotationRepository
├── training.py # TrainingRepository
├── dataset.py # DatasetRepository
└── model.py # ModelRepository
```
#### 1.2 统一配置
```python
# 创建统一配置模块
inference/config/
├── __init__.py
├── settings.py # Pydantic Settings
└── validators.py # 配置验证
```
### Phase 2: 短期执行 (本月)
#### 2.1 引入消息队列
```yaml
# docker-compose.yml 添加
services:
redis:
image: redis:7-alpine
ports:
- "6379:6379"
celery_worker:
build: .
command: celery -A inference.tasks worker -l info
depends_on:
- redis
- postgres
```
#### 2.2 添加缓存层
```python
# 使用 Redis 缓存热点数据
from redis import Redis
redis_client = Redis(host='localhost', port=6379)
class CachedDocumentRepository(DocumentRepository):
def find_by_id(self, doc_id: str) -> Document | None:
# 先查缓存
cached = redis_client.get(f"doc:{doc_id}")
if cached:
return Document.parse_raw(cached)
# 再查数据库
doc = super().find_by_id(doc_id)
if doc:
redis_client.setex(f"doc:{doc_id}", 3600, doc.json())
return doc
```
### Phase 3: 长期执行 (本季度)
#### 3.1 数据库读写分离
```python
# 配置主从数据库
class DatabaseManager:
def __init__(self):
self._master = create_engine(MASTER_DB_URL)
self._replica = create_engine(REPLICA_DB_URL)
def get_session(self, readonly: bool = False) -> Session:
engine = self._replica if readonly else self._master
return Session(engine)
```
#### 3.2 事件驱动架构
```python
# 引入事件总线
from event_bus import EventBus
bus = EventBus()
# 发布事件
@router.post("/documents")
async def create_document(...):
doc = document_repo.save(document)
bus.publish('document.created', {'document_id': doc.id})
return doc
# 订阅事件
@bus.subscribe('document.created')
def on_document_created(event):
# 触发自动标注
auto_label_task.delay(event['document_id'])
```

## 改进建议
### 立即执行 (高优先级)
1. **提升测试覆盖率**
```bash
# 目标: 60%+
pytest tests/ --cov=packages --cov-report=html
```
- 优先测试 `inference/pipeline/`
- 添加 API 集成测试
- 添加存储层测试
2. **加强文件上传安全**
```python
# 添加文件类型验证
ALLOWED_EXTENSIONS = {".pdf"}
MAX_FILE_SIZE = 10 * 1024 * 1024
# 验证 PDF 魔数
if not content.startswith(b"%PDF"):
raise HTTPException(400, "Invalid PDF file format")
```
3. **修复时序攻击漏洞**
```python
import hmac
def verify_token(token: str, expected: str) -> bool:
return hmac.compare_digest(token, expected)
```
### 短期执行 (中优先级)
4. **添加路径遍历防护**
```python
from pathlib import Path
def get_safe_path(filename: str, base_dir: Path) -> Path:
safe_name = Path(filename).name
full_path = (base_dir / safe_name).resolve()
if not full_path.is_relative_to(base_dir):
raise HTTPException(400, "Invalid file path")
return full_path
```
5. **配置 CORS 白名单**
```python
ALLOWED_ORIGINS = [
"http://localhost:5173",
"https://your-domain.com",
]
```
6. **添加安全测试**
```python
def test_sql_injection_prevented(client):
response = client.get("/api/v1/documents?id='; DROP TABLE;")
assert response.status_code in (400, 422)
def test_path_traversal_prevented(client):
response = client.get("/api/v1/results/../../etc/passwd")
assert response.status_code == 400
```
### 长期执行 (低优先级)
7. **依赖安全审计**
```bash
pip install pip-audit
pip-audit --desc --format=json > security-audit.json
```
8. **代码质量工具**
```bash
# 添加 pre-commit hooks
pip install pre-commit
pre-commit install
```
9. **性能监控**
- 添加 APM 工具 (如 Datadog, New Relic)
- 设置性能基准测试

## 2. 代码质量问题
### 2.1 长函数（>50 行）🔴
| 函数 | 文件 | 行数 | 复杂度 | 问题 |
|------|------|------|--------|------|
| `_normalize_customer_number()` | field_extractor.py | **127** | 极高 | 4 层模式匹配，7+ 正则，复杂评分 |
| `_cross_validate_payment_line()` | pipeline.py | **127** | 极高 | 核心验证逻辑，8+ 条件分支 |
| `_normalize_bankgiro()` | field_extractor.py | 62 | 高 | Luhn 验证 + 多种降级 |
| `_normalize_plusgiro()` | field_extractor.py | 63 | 高 | 类似 bankgiro |
| `_normalize_payment_line()` | field_extractor.py | 74 | 高 | 4 种正则模式 |
| `_normalize_amount()` | field_extractor.py | 78 | 高 | 多策略降级 |
**示例问题** - `_normalize_customer_number()` (第 776-902 行):
```python
def _normalize_customer_number(self, text: str):
# 127 行函数，包含：
# - 4 个嵌套的 if/for 循环
# - 7 种不同的正则模式
# - 5 个评分机制
# - 处理有标签和无标签格式
```
**建议**: 拆分为：
- `_find_customer_code_patterns()`
- `_find_labeled_customer_code()`
- `_score_customer_candidates()`
### 2.2 代码重复 🔴
**支付行解析（3+ 处重复实现）**:
1. `_parse_machine_readable_payment_line()` (pipeline.py:217-252)
2. `MachineCodeParser.parse()` (machine_code_parser.py:919 行)
3. `_normalize_payment_line()` (field_extractor.py:632-705)
所有三处都实现类似的正则模式：
```
格式: # <OCR> # <Kronor> <Öre> <Type> > <Account>#<Check>#
```
**Bankgiro/Plusgiro 验证（重复）**:
- `validators.py`: `is_valid_bankgiro()`, `format_bankgiro()`
- `field_extractor.py`: `_normalize_bankgiro()`, `_normalize_plusgiro()`, `_luhn_checksum()`
- `normalizer.py`: `normalize_bankgiro()`, `normalize_plusgiro()`
- `field_matcher.py`: 类似匹配逻辑
**建议**: 创建统一模块：
```python
# src/common/payment_line_parser.py
class PaymentLineParser:
def parse(text: str) -> PaymentLineResult
# src/common/giro_validator.py
class GiroValidator:
def validate_and_format(value: str, giro_type: str) -> str
```
### 2.3 错误处理不一致 ⚠️
**通用异常捕获（31 处）**:
```python
except Exception as e: # 代码库中 31 处
result.errors.append(str(e))
```
**问题**:
- 没有捕获特定错误类型
- 通用错误消息丢失上下文
- 第 142-147 行 (routes.py): 捕获所有异常，返回 500 状态
**当前写法** (routes.py:142-147):
```python
try:
service_result = inference_service.process_pdf(...)
except Exception as e: # 太宽泛
logger.error(f"Error processing document: {e}")
raise HTTPException(status_code=500, detail=str(e))
```
**改进建议**:
```python
except FileNotFoundError:
raise HTTPException(status_code=400, detail="PDF 文件未找到")
except PyMuPDFError:
raise HTTPException(status_code=400, detail="无效的 PDF 格式")
except OCRError:
raise HTTPException(status_code=503, detail="OCR 服务不可用")
```
### 2.4 配置安全问题 🔴
**config.py 第 24-30 行** - 明文凭据：
```python
DATABASE = {
'host': '192.168.68.31', # 硬编码 IP
'user': 'docmaster', # 硬编码用户名
'password': 'nY6LYK5d', # 🔴 明文密码！
'database': 'invoice_master'
}
```
**建议**:
```python
DATABASE = {
'host': os.getenv('DB_HOST', 'localhost'),
'user': os.getenv('DB_USER', 'docmaster'),
'password': os.getenv('DB_PASSWORD'), # 从环境变量读取
'database': os.getenv('DB_NAME', 'invoice_master')
}
```
### 2.5 魔法数字 ⚠️
| 值 | 位置 | 用途 | 问题 |
|---|------|------|------|
| 0.5 | 多处 | 置信度阈值 | 不可按字段配置 |
| 0.95 | pipeline.py | payment_line 置信度 | 无说明 |
| 300 | 多处 | DPI | 硬编码 |
| 0.1 | field_extractor.py | BBox 填充 | 应为配置 |
| 72 | 多处 | PDF 基础 DPI | 公式中的魔法数字 |
| 50 | field_extractor.py | 客户编号评分加分 | 无说明 |
**建议**: 提取到配置：
```python
INFERENCE_CONFIG = {
'confidence_threshold': 0.5,
'payment_line_confidence': 0.95,
'dpi': 300,
'bbox_padding': 0.1,
}
```
### 2.6 命名不一致 ⚠️
**字段名称不一致**:
- YOLO 类名: `invoice_number`, `ocr_number`, `supplier_org_number`
- 字段名: `InvoiceNumber`, `OCR`, `supplier_org_number`
- CSV 列名: 可能又不同
- 数据库字段名: 另一种变体
映射维护在多处：
- `yolo_detector.py` (90-100 行): `CLASS_TO_FIELD`
- 多个其他位置
---
## 3. 测试分析
### 3.1 测试覆盖率
**测试文件**: 13 个
- ✅ 覆盖良好: field_matcher, normalizer, payment_line_parser
- ⚠️ 中等覆盖: field_extractor, pipeline
- ❌ 覆盖不足: web 层, CLI, 批处理
**估算覆盖率**: 40-50%
### 3.2 缺失的测试用例 🔴
**关键缺失**:
1. 交叉验证逻辑 - 最复杂部分，测试很少
2. payment_line 解析变体 - 多种实现，边界情况不清楚
3. OCR 错误纠正 - 不同策略的复杂逻辑
4. Web API 端点 - 没有请求/响应测试
5. 批处理 - 多 worker 协调未测试
6. 降级 OCR 机制 - YOLO 检测失败时
---
## 4. 架构风险
### 🔴 关键风险
1. **配置安全** - config.py 中明文数据库凭据（24-30 行）
2. **错误恢复** - 宽泛的异常处理掩盖真实问题
3. **可测试性** - 硬编码依赖阻止单元测试
### 🟡 高风险
1. **代码可维护性** - 支付行解析重复
2. **可扩展性** - 没有长时间推理的异步处理
3. **扩展性** - 添加新字段类型会很困难
### 🟢 中等风险
1. **性能** - 懒加载有帮助，但 ORM 查询未优化
2. **文档** - 大部分足够但可以更好
---
## 5. 优先级矩阵
| 优先级 | 行动 | 工作量 | 影响 |
|--------|------|--------|------|
| 🔴 关键 | 修复配置安全（环境变量） | 1 小时 | 高 |
| 🔴 关键 | 添加集成测试 | 2-3 天 | 高 |

# Field Extractor 分析报告
## 概述
field_extractor.py (1183行) 最初被识别为可优化文件，尝试使用 `src/normalize` 模块进行重构，但经过分析和测试后发现 **不应该重构**。
## 重构尝试
### 初始计划
将 field_extractor.py 中的重复 normalize 方法删除，统一使用 `src/normalize/normalize_field()` 接口。
### 实施步骤
1. ✅ 备份原文件 (`field_extractor_old.py`)
2. ✅ 修改 `_normalize_and_validate` 使用统一 normalizer
3. ✅ 删除重复的 normalize 方法 (~400行)
4. ❌ 运行测试 - **28个失败**
5. ✅ 添加 wrapper 方法委托给 normalizer
6. ❌ 再次测试 - **12个失败**
7. ✅ 还原原文件
8. ✅ 测试通过 - **全部45个测试通过**
## 关键发现
### 两个模块的不同用途
| 模块 | 用途 | 输入 | 输出 | 示例 |
|------|------|------|------|------|
| **src/normalize/** | **变体生成** 用于匹配 | 已提取的字段值 | 多个匹配变体列表 | `"INV-12345"` → `["INV-12345", "12345"]` |
| **field_extractor** | **值提取** 从OCR文本 | 包含字段的原始OCR文本 | 提取的单个字段值 | `"Fakturanummer: A3861"` → `"A3861"` |
### 为什么不能统一？
1. **src/normalize/** 的设计目的:
- 接收已经提取的字段值
- 生成多个标准化变体用于fuzzy matching
- 例如 BankgiroNormalizer:
```python
normalize("782-1713") → ["7821713", "782-1713"] # 生成变体
```
2. **field_extractor** 的 normalize 方法:
- 接收包含字段的原始OCR文本（可能包含标签、其他文本等）
- **提取**特定模式的字段值
- 例如 `_normalize_bankgiro`:
```python
_normalize_bankgiro("Bankgiro: 782-1713") → ("782-1713", True, None) # 从文本提取
```
3. **关键区别**:
- Normalizer: 变体生成器 (for matching)
- Field Extractor: 模式提取器 (for parsing)
### 测试失败示例
使用 normalizer 替代 field extractor 方法后的失败:
```python
# InvoiceNumber 测试
Input: "Fakturanummer: A3861"
期望: "A3861"
实际: "Fakturanummer: A3861" # 没有提取，只是清理
# Bankgiro 测试
Input: "Bankgiro: 782-1713"
期望: "782-1713"
实际: "7821713" # 返回了不带破折号的变体，而不是提取格式化值
```
## 结论
**field_extractor.py 不应该使用 src/normalize 模块重构**，因为:
1. ✅ **职责不同**: 提取 vs 变体生成
2. ✅ **输入不同**: 包含标签的原始OCR文本 vs 已提取的字段值
3. ✅ **输出不同**: 单个提取值 vs 多个匹配变体
4. ✅ **现有代码运行良好**: 所有45个测试通过
5. ✅ **提取逻辑有价值**: 包含复杂的模式匹配规则（例如区分 Bankgiro/Plusgiro 格式）
## 建议
1. **保留 field_extractor.py 原样**: 不进行重构
2. **文档化两个模块的差异**: 确保团队理解各自用途
3. **关注其他优化目标**: machine_code_parser.py (919行)
## 学习点
重构前应该:
1. 理解模块的**真实用途**，而不只是看代码相似度
2. 运行完整测试套件验证假设
3. 评估是否真的存在重复，还是表面相似但用途不同
---
**状态**: ✅ 分析完成，决定不重构
**测试**: ✅ 45/45 通过
**文件**: 保持 1183行 原样

# Machine Code Parser 分析报告
## 文件概况
- **文件**: `src/ocr/machine_code_parser.py`
- **总行数**: 919 行
- **代码行**: 607 行 (66%)
- **方法数**: 14 个
- **正则表达式使用**: 47 次
## 代码结构
### 类结构
```
MachineCodeResult (数据类)
├── to_dict()
└── get_region_bbox()
MachineCodeParser (主解析器)
├── __init__()
├── parse() - 主入口
├── _find_tokens_with_values()
├── _find_machine_code_line_tokens()
├── _parse_standard_payment_line_with_tokens()
├── _parse_standard_payment_line() - 142行 ⚠️
├── _extract_ocr() - 50行
├── _extract_bankgiro() - 58行
├── _extract_plusgiro() - 30行
├── _extract_amount() - 68行
├── _calculate_confidence()
└── cross_validate()
```
## 发现的问题
### 1. ⚠️ `_parse_standard_payment_line` 方法过长 (142行)
**位置**: 442-582 行
**问题**:
- 包含嵌套函数 `normalize_account_spaces` 和 `format_account`
- 多个正则匹配分支
- 逻辑复杂，难以测试和维护
**建议**:
可以拆分为独立方法:
- `_normalize_account_spaces(line)`
- `_format_account(account_digits, context)`
- `_match_primary_pattern(line)`
- `_match_fallback_patterns(line)`
### 2. 🔁 4个 `_extract_*` 方法有重复模式
所有 extract 方法都遵循相同模式：
```python
def _extract_XXX(self, tokens):
candidates = []
for token in tokens:
text = token.text.strip()
matches = self.XXX_PATTERN.findall(text)
for match in matches:
# 验证逻辑
# 上下文检测
candidates.append((normalized, context_score, token))
if not candidates:
return None
candidates.sort(key=lambda x: (x[1], 1), reverse=True)
return candidates[0][0]
```
**重复的逻辑**:
- Token 迭代
- 模式匹配
- 候选收集
- 上下文评分
- 排序和选择最佳匹配
**建议**:
可以提取基础提取器类或通用方法来减少重复。
### 3. ✅ 上下文检测重复
上下文检测代码在多个地方重复：
```python
# _extract_bankgiro 中
context_text = ' '.join(t.text.lower() for t in tokens)
is_bankgiro_context = (
'bankgiro' in context_text or
'bg:' in context_text or
'bg ' in context_text
)
# _extract_plusgiro 中
context_text = ' '.join(t.text.lower() for t in tokens)
is_plusgiro_context = (
'plusgiro' in context_text or
'postgiro' in context_text or
'pg:' in context_text or
'pg ' in context_text
)
# _parse_standard_payment_line 中
context = (context_line or raw_line).lower()
is_plusgiro_context = (
('plusgiro' in context or 'postgiro' in context or 'plusgirokonto' in context)
and 'bankgiro' not in context
)
```
**建议**:
提取为独立方法:
- `_detect_account_context(tokens) -> dict[str, bool]`
## 重构建议
### 方案 A: 轻度重构（推荐）✅
**目标**: 提取重复的上下文检测逻辑，不改变主要结构
**步骤**:
1. 提取 `_detect_account_context(tokens)` 方法
2. 提取 `_normalize_account_spaces(line)` 为独立方法
3. 提取 `_format_account(digits, context)` 为独立方法
**影响**:
- 减少 ~50-80 行重复代码
- 提高可测试性
- 低风险，易于验证
**预期结果**: 919 行 → ~850 行 (↓7%)
### 方案 B: 中度重构
**目标**: 创建通用的字段提取框架
**步骤**:
1. 创建 `_generic_extract(pattern, normalizer, context_checker)`
2. 重构所有 `_extract_*` 方法使用通用框架
3. 拆分 `_parse_standard_payment_line` 为多个小方法
**影响**:
- 减少 ~150-200 行代码
- 显著提高可维护性
- 中等风险，需要全面测试
**预期结果**: 919 行 → ~720 行 (↓22%)
### 方案 C: 深度重构（不推荐）
**目标**: 完全重新设计为策略模式
**风险**:
- 高风险，可能引入 bugs
- 需要大量测试
- 可能破坏现有集成
## 推荐方案
### ✅ 采用方案 A（轻度重构）
**理由**:
1. **代码已经工作良好**: 没有明显的 bug 或性能问题
2. **低风险**: 只提取重复逻辑，不改变核心算法
3. **性价比高**: 小改动带来明显的代码质量提升
4. **易于验证**: 现有测试应该能覆盖
### 重构步骤
```python
# 1. 提取上下文检测
def _detect_account_context(self, tokens: list[TextToken]) -> dict[str, bool]:
"""检测上下文中的账户类型关键词"""
context_text = ' '.join(t.text.lower() for t in tokens)
return {
'bankgiro': any(kw in context_text for kw in ['bankgiro', 'bg:', 'bg ']),
'plusgiro': any(kw in context_text for kw in ['plusgiro', 'postgiro', 'plusgirokonto', 'pg:', 'pg ']),
}
# 2. 提取空格标准化
def _normalize_account_spaces(self, line: str) -> str:
"""移除账户号码中的空格"""
# (现有 line 460-481 的代码)
# 3. 提取账户格式化
def _format_account(
self,
account_digits: str,
is_plusgiro_context: bool
) -> tuple[str, str]:
"""格式化账户并确定类型"""
# (现有 line 485-523 的代码)
```
## 对比：field_extractor vs machine_code_parser
| 特征 | field_extractor | machine_code_parser |
|------|-----------------|---------------------|
| 用途 | 值提取 | 机器码解析 |
| 重复代码 | ~400行normalize方法 | ~80行上下文检测 |
| 重构价值 | ❌ 不同用途，不应统一 | ✅ 可提取共享逻辑 |
| 风险 | 高（会破坏功能） | 低（只是代码组织） |
## 决策
### ✅ 建议重构 machine_code_parser.py
**与 field_extractor 的不同**:
- field_extractor: 重复的方法有**不同的用途**（提取 vs 变体生成）
- machine_code_parser: 重复的代码有**相同的用途**（都是上下文检测）
**预期收益**:
- 减少 ~70 行重复代码
- 提高可测试性（可以单独测试上下文检测）
- 更清晰的代码组织
- **低风险**，易于验证
## 下一步
1. ✅ 备份原文件
2. ✅ 提取 `_detect_account_context` 方法
3. ✅ 提取 `_normalize_account_spaces` 方法
4. ✅ 提取 `_format_account` 方法
5. ✅ 更新所有调用点
6. ✅ 运行测试验证
7. ✅ 检查代码覆盖率
---
**状态**: 📋 分析完成，建议轻度重构

# Performance Optimization Guide
This document provides performance optimization recommendations for the Invoice Field Extraction system.
## Table of Contents
1. [Batch Processing Optimization](#batch-processing-optimization)
2. [Database Query Optimization](#database-query-optimization)
3. [Caching Strategies](#caching-strategies)
4. [Memory Management](#memory-management)
5. [Profiling and Monitoring](#profiling-and-monitoring)
---
## Batch Processing Optimization
### Current State
The system processes invoices one at a time. For large batches, this can be inefficient.
### Recommendations
#### 1. Database Batch Operations
**Current**: Individual inserts for each document
```python
# Inefficient
for doc in documents:
db.insert_document(doc) # Individual DB call
```
**Optimized**: Use `execute_values` for batch inserts
```python
# Efficient - already implemented in db.py line 519
from psycopg2.extras import execute_values
execute_values(cursor, """
INSERT INTO documents (...)
VALUES %s
""", document_values)
```
**Impact**: 10-50x faster for batches of 100+ documents
#### 2. PDF Processing Batching
**Recommendation**: Process PDFs in parallel using multiprocessing
```python
from multiprocessing import Pool
def process_batch(pdf_paths, batch_size=10):
"""Process PDFs in parallel batches."""
with Pool(processes=batch_size) as pool:
results = pool.map(pipeline.process_pdf, pdf_paths)
return results
```
**Considerations**:
- GPU models should use a shared process pool (already exists: `src/processing/gpu_pool.py`)
- CPU-intensive tasks can use separate process pool (`src/processing/cpu_pool.py`)
- Current dual pool coordinator (`dual_pool_coordinator.py`) already supports this pattern
**Status**: ✅ Already implemented in `src/processing/` modules
#### 3. Image Caching for Multi-Page PDFs
**Current**: Each page rendered independently
```python
# Current pattern in field_extractor.py
for page_num in range(total_pages):
image = render_pdf_page(pdf_path, page_num, dpi=300)
```
**Optimized**: Pre-render all pages if processing multiple fields per page
```python
# Batch render
images = {
page_num: render_pdf_page(pdf_path, page_num, dpi=300)
for page_num in page_numbers_needed
}
# Reuse images
for detection in detections:
image = images[detection.page_no]
extract_field(detection, image)
```
**Impact**: Reduces redundant PDF rendering by 50-90% for multi-field invoices
---
## Database Query Optimization
### Current Performance
- **Parameterized queries**: ✅ Implemented (Phase 1)
- **Connection pooling**: ❌ Not implemented
- **Query batching**: ✅ Partially implemented
- **Index optimization**: ⚠️ Needs verification
### Recommendations
#### 1. Connection Pooling
**Current**: New connection for each operation
```python
def connect(self):
"""Create new database connection."""
return psycopg2.connect(**self.config)
```
**Optimized**: Use connection pooling
```python
from psycopg2 import pool
class DocumentDatabase:
def __init__(self, config):
self.pool = pool.SimpleConnectionPool(
minconn=1,
maxconn=10,
**config
)
def connect(self):
return self.pool.getconn()
def close(self, conn):
self.pool.putconn(conn)
```
**Impact**:
- Reduces connection overhead by 80-95%
- Especially important for high-frequency operations
#### 2. Index Recommendations
**Check current indexes**:
```sql
-- Verify indexes exist on frequently queried columns
SELECT tablename, indexname, indexdef
FROM pg_indexes
WHERE schemaname = 'public';
```
**Recommended indexes**:
```sql
-- If not already present
CREATE INDEX IF NOT EXISTS idx_documents_success
ON documents(success);
CREATE INDEX IF NOT EXISTS idx_documents_timestamp
ON documents(timestamp DESC);
CREATE INDEX IF NOT EXISTS idx_field_results_document_id
ON field_results(document_id);
CREATE INDEX IF NOT EXISTS idx_field_results_matched
ON field_results(matched);
CREATE INDEX IF NOT EXISTS idx_field_results_field_name
ON field_results(field_name);
```
**Impact**:
- 10-100x faster queries for filtered/sorted results
- Critical for `get_failed_matches()` and `get_all_documents_summary()`
#### 3. Query Batching
**Status**: ✅ Already implemented for field results (line 519)
**Verify batching is used**:
```python
# Good pattern in db.py
execute_values(cursor, "INSERT INTO field_results (...) VALUES %s", field_values)
```
**Additional opportunity**: Batch `SELECT` queries
```python
# Current
docs = [get_document(doc_id) for doc_id in doc_ids] # N queries
# Optimized
docs = get_documents_batch(doc_ids) # 1 query with IN clause
```
**Status**: ✅ Already implemented (`get_documents_batch` exists in db.py)
---
## Caching Strategies
### 1. Model Loading Cache
**Current**: Models loaded per-instance
**Recommendation**: Singleton pattern for YOLO model
```python
class YOLODetectorSingleton:
_instance = None
_model = None
@classmethod
def get_instance(cls, model_path):
if cls._instance is None:
cls._instance = YOLODetector(model_path)
return cls._instance
```
**Impact**: Reduces memory usage by 90% when processing multiple documents
### 2. Parser Instance Caching
**Current**: ✅ Already optimal
```python
# Good pattern in field_extractor.py
def __init__(self):
self.payment_line_parser = PaymentLineParser() # Reused
self.customer_number_parser = CustomerNumberParser() # Reused
```
**Status**: No changes needed
### 3. OCR Result Caching
**Recommendation**: Cache OCR results for identical regions
```python
from functools import lru_cache
@lru_cache(maxsize=1000)
def ocr_region_cached(image_hash, bbox):
"""Cache OCR results by image hash + bbox."""
return paddle_ocr.ocr_region(image, bbox)
```
**Impact**: 50-80% speedup when re-processing similar documents
**Note**: Requires implementing image hashing (e.g., `hashlib.md5(image.tobytes())`)
---
## Memory Management
### Current Issues
**Potential memory leaks**:
1. Large images kept in memory after processing
2. OCR results accumulated without cleanup
3. Model outputs not explicitly cleared
### Recommendations
#### 1. Explicit Image Cleanup
```python
import gc
def process_pdf(pdf_path):
try:
image = render_pdf(pdf_path)
result = extract_fields(image)
return result
finally:
del image # Explicit cleanup
gc.collect() # Force garbage collection
```
#### 2. Generator Pattern for Large Batches
**Current**: Load all documents into memory
```python
docs = [process_pdf(path) for path in pdf_paths] # All in memory
```
**Optimized**: Use generator for streaming processing
```python
def process_batch_streaming(pdf_paths):
"""Process documents one at a time, yielding results."""
for path in pdf_paths:
result = process_pdf(path)
yield result
# Result can be saved to DB immediately
# Previous result is garbage collected
```
**Impact**: Constant memory usage regardless of batch size
#### 3. Context Managers for Resources
```python
class InferencePipeline:
def __enter__(self):
self.detector.load_model()
return self
def __exit__(self, *args):
self.detector.unload_model()
self.extractor.cleanup()
# Usage
with InferencePipeline(...) as pipeline:
results = pipeline.process_pdf(path)
# Automatic cleanup
```
---
## Profiling and Monitoring
### Recommended Profiling Tools
#### 1. cProfile for CPU Profiling
```python
import cProfile
import pstats
profiler = cProfile.Profile()
profiler.enable()
# Your code here
pipeline.process_pdf(pdf_path)
profiler.disable()
stats = pstats.Stats(profiler)
stats.sort_stats('cumulative')
stats.print_stats(20) # Top 20 slowest functions
```
#### 2. memory_profiler for Memory Analysis
```bash
pip install memory_profiler
python -m memory_profiler your_script.py
```
Or decorator-based:
```python
from memory_profiler import profile
@profile
def process_large_batch(pdf_paths):
# Memory usage tracked line-by-line
results = [process_pdf(path) for path in pdf_paths]
return results
```
#### 3. py-spy for Production Profiling
```bash
pip install py-spy
# Profile running process
py-spy top --pid 12345
# Generate flamegraph
py-spy record -o profile.svg -- python your_script.py
```
**Advantage**: No code changes needed, minimal overhead
### Key Metrics to Monitor
1. **Processing Time per Document**
- Target: <10 seconds for single-page invoice
- Current: ~2-5 seconds (estimated)
2. **Memory Usage**
- Target: <2GB for batch of 100 documents
- Monitor: Peak memory usage
3. **Database Query Time**
- Target: <100ms per query (with indexes)
- Monitor: Slow query log
4. **OCR Accuracy vs Speed Trade-off**
- Current: PaddleOCR with GPU (~200ms per region)
- Alternative: Tesseract (~500ms, slightly more accurate)
### Logging Performance Metrics
**Add to pipeline.py**:
```python
import time
import logging
logger = logging.getLogger(__name__)
def process_pdf(self, pdf_path):
start = time.time()
# Processing...
result = self._process_internal(pdf_path)
elapsed = time.time() - start
logger.info(f"Processed {pdf_path} in {elapsed:.2f}s")
# Log to database for analysis
self.db.log_performance({
'document_id': result.document_id,
'processing_time': elapsed,
'field_count': len(result.fields)
})
return result
```
---
## Performance Optimization Priorities
### High Priority (Implement First)
1. ✅ **Database parameterized queries** - Already done (Phase 1)
2. ⚠️ **Database connection pooling** - Not implemented
3. ⚠️ **Index optimization** - Needs verification
### Medium Priority
4. ⚠️ **Batch PDF rendering** - Optimization possible
5. ✅ **Parser instance reuse** - Already done (Phase 2)
6. ⚠️ **Model caching** - Could improve
### Low Priority (Nice to Have)
7. ⚠️ **OCR result caching** - Complex implementation
8. ⚠️ **Generator patterns** - Refactoring needed
9. ⚠️ **Advanced profiling** - For production optimization
---
## Benchmarking Script
```python
"""
Benchmark script for invoice processing performance.
"""
import time
from pathlib import Path
from src.inference.pipeline import InferencePipeline
def benchmark_single_document(pdf_path, iterations=10):

## 🎓 重构经验总结
### 成功经验
1. **✅ 先测试后重构**
- 所有重构都有完整测试覆盖
- 每次改动后立即验证测试
- 100%测试通过率保证质量
2. **✅ 识别真正的重复**
- 不是所有相似代码都是重复
- field_extractor vs normalizer: 表面相似但用途不同
- machine_code_parser: 真正的代码重复
3. **✅ 渐进式重构**
- matcher: 大规模模块化 (策略模式)
- machine_code_parser: 轻度重构 (提取共享方法)
- field_extractor: 分析后决定不重构
### 关键决策
#### ✅ 应该重构的情况
- **matcher**: 单一文件过长 (876行)，包含多种策略
- **machine_code_parser**: 多处相同用途的重复代码
#### ❌ 不应重构的情况
- **field_extractor**: 相似代码有不同用途
### 教训
**不要盲目追求DRY原则**
> 相似代码不一定是重复。要理解代码的**真实用途**。
---
## ✅ 总结
**关键成果**:
- 📉 净减少 195 行代码
- 📈 代码覆盖率 +3% (34% → 37%)
- ✅ 测试数量 +55 (633 → 688)
- 🎯 machine_code_parser 覆盖率 +40% (25% → 65%)
- ✨ 模块化程度显著提高
- 🎯 可维护性大幅提升
**重要教训**:
> 相似的代码不一定是重复的代码。理解代码的真实用途，才能做出正确的重构决策。
**下一步建议**:
1. 继续提升 machine_code_parser 覆盖率到 80%+ (目前 65%)
2. 为其他低覆盖模块添加测试（field_extractor 39%, pipeline 19%）
3. 完善边界条件和异常情况的测试

---
## 存储方案
### Amazon S3（推荐）
S3 是 AWS 的核心存储服务，与 SageMaker 深度集成。
```bash
# 创建 S3 桶
aws s3 mb s3://invoice-training-data --region us-east-1
# 上传训练数据
aws s3 sync ./data/dataset/temp s3://invoice-training-data/images/
# 创建目录结构
aws s3api put-object --bucket invoice-training-data --key datasets/
aws s3api put-object --bucket invoice-training-data --key models/
```
### Mountpoint for Amazon S3
AWS 官方的 S3 挂载客户端，性能优于 s3fs：
```bash
# 安装 Mountpoint
wget https://s3.amazonaws.com/mountpoint-s3-release/latest/x86_64/mount-s3.deb
sudo dpkg -i mount-s3.deb
# 挂载 S3
mkdir -p /mnt/s3-data
mount-s3 invoice-training-data /mnt/s3-data --region us-east-1
# 配置缓存（推荐）
mount-s3 invoice-training-data /mnt/s3-data \
--region us-east-1 \
--cache /tmp/s3-cache \
--metadata-ttl 60
```
### 本地开发挂载
**Linux/Mac (s3fs-fuse):**
```bash
# 安装
sudo apt-get install s3fs
# 配置凭证
echo ACCESS_KEY_ID:SECRET_ACCESS_KEY > ~/.passwd-s3fs
chmod 600 ~/.passwd-s3fs
# 挂载
s3fs invoice-training-data /mnt/s3 -o passwd_file=~/.passwd-s3fs
```
**Windows (Rclone):**
```powershell
# 安装
winget install Rclone.Rclone
# 配置
rclone config # 选择 s3
# 挂载
rclone mount aws:invoice-training-data Z: --vfs-cache-mode full
```
### 存储费用

| S3 Intelligent-Tiering | $0.023/GB/月 | 自动分层 |
| S3 Infrequent Access | $0.0125/GB/月 | 偶尔访问 |
| S3 Glacier | $0.004/GB/月 | 长期存档 |
**本项目**: ~10,000 张图片 × 500KB = ~5GB → **~$0.12/月**
### SageMaker 数据输入模式
| 模式 | 说明 | 适用场景 |
|------|------|---------|
| File Mode | 下载到本地再训练 | 小数据集 |
| Pipe Mode | 流式读取，不占本地空间 | 大数据集 |
| FastFile Mode | 按需下载，最高 3x 加速 | 推荐 |

### 推荐方案 1: AWS Lambda (低流量)
对于 YOLO CPU 推理，Lambda 最经济：
```python
# lambda_function.py
import json
import boto3
from ultralytics import YOLO
# 模型在 Lambda Layer 或 /tmp 加载
model = None
def load_model():
global model
if model is None:
# 从 S3 下载模型到 /tmp
s3 = boto3.client('s3')
s3.download_file('invoice-models', 'best.pt', '/tmp/best.pt')
model = YOLO('/tmp/best.pt')
return model
def lambda_handler(event, context):
model = load_model()
# 从 S3 获取图片
s3 = boto3.client('s3')
bucket = event['bucket']
key = event['key']
local_path = f'/tmp/{key.split("/")[-1]}'
s3.download_file(bucket, key, local_path)
# 执行推理
results = model.predict(local_path, conf=0.5)
return {
'statusCode': 200,
'body': json.dumps({
'fields': extract_fields(results),
'confidence': get_confidence(results)
})
}
```
**Lambda 配置:**
```yaml
# serverless.yml
service: invoice-inference
provider:
name: aws
runtime: python3.11
timeout: 30
memorySize: 4096 # 4GB 内存
functions:
infer:
handler: lambda_function.lambda_handler
events:
- http:
path: /infer
method: post
layers:
- arn:aws:lambda:us-east-1:123456789012:layer:yolo-deps:1
```
### 推荐方案 2: ECS Fargate (中流量)

--service-namespace ecs \
--resource-id service/invoice-cluster/invoice-service \
--scalable-dimension ecs:service:DesiredCount \
--min-capacity 1 \
--max-capacity 10
# 基于 CPU 使用率扩缩容
aws application-autoscaling put-scaling-policy \
--service-namespace ecs \
--resource-id service/invoice-cluster/invoice-service \
--scalable-dimension ecs:service:DesiredCount \
--policy-name cpu-scaling \

"TargetValue": 70,
"PredefinedMetricSpecification": {
"PredefinedMetricType": "ECSServiceAverageCPUUtilization"
},
"ScaleOutCooldown": 60,
"ScaleInCooldown": 120
}'
```
### 方案 3: SageMaker Serverless Inference
```python
from sagemaker.serverless import ServerlessInferenceConfig
from sagemaker.pytorch import PyTorchModel
model = PyTorchModel(
model_data="s3://invoice-models/model.tar.gz",
role="arn:aws:iam::123456789012:role/SageMakerRole",
entry_point="inference.py",
framework_version="2.0",
py_version="py310"
)
serverless_config = ServerlessInferenceConfig(
memory_size_in_mb=4096,
max_concurrency=10
)
predictor = model.deploy(
serverless_inference_config=serverless_config,
endpoint_name="invoice-inference-serverless"
)
```
### 推理性能对比
| 配置 | 单次推理时间 | 并发能力 | 月费估算 |
|------|------------|---------|---------|

|------|---------|---------|
| 数据存储 | S3 Standard | ~$0.12 |
| 数据库 | RDS db.t3.micro | ~$15 |
| 推理服务 | Lambda 4GB | ~$15 |
| 训练服务 | SageMaker Spot | 按需 ~$2-5/次 |
| ECR | 基本使用 | ~$1 |
| **总计** | | **~$35/月** + 训练费 |
### 关键决策
| 场景 | 选择 |
|------|------|

| MLOps 集成 | SageMaker 全家桶 |
### 注意事项
1. **Lambda 冷启动**: 首次调用 ~3-5 秒，可用 Provisioned Concurrency 解决
2. **Spot 中断**: 配置检查点，SageMaker 自动恢复
3. **S3 传输**: 同区域免费，跨区域收费
4. **Fargate 无 GPU**: 需要 GPU 必须用 ECS + EC2
5. **SageMaker 加价**: 比 EC2 贵 ~25%，但省管理成本

## 推理方案
### 方案对比
| 方案 | GPU 支持 | 扩缩容 | 价格 | 适用场景 |
|------|---------|--------|------|---------|
| Container Apps (CPU) | 否 | 自动 0-N | ~$30/月 | YOLO 推理 (够用) |

### 推荐: Container Apps (CPU)
对于 YOLO 推理，**CPU 足够**，不需要 GPU：
- YOLOv11n 在 CPU 上推理时间 ~200-500ms
- 比 GPU 便宜很多，适合中低流量
```yaml
# Container Apps 配置
name: invoice-inference
image: myacr.azurecr.io/invoice-inference:v1
resources:
cpu: 2.0
memory: 4Gi
scale:
minReplicas: 1 # 最少 1 个实例保持响应
maxReplicas: 10 # 最多扩展到 10 个
rules:
- name: http-scaling
http:
metadata:
concurrentRequests: "50" # 每实例 50 并发时扩容
```
### 推理服务代码示例
```python
# Dockerfile
FROM python:3.11-slim
WORKDIR /app
# 安装依赖
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
# 复制代码和模型
COPY src/ ./src/
COPY models/best.pt ./models/
# 启动服务
CMD ["uvicorn", "src.web.app:app", "--host", "0.0.0.0", "--port", "8000"]
```
```python
# src/web/app.py
from fastapi import FastAPI, UploadFile, File
from ultralytics import YOLO
import tempfile
app = FastAPI()
model = YOLO("models/best.pt")
@app.post("/api/v1/infer")
async def infer(file: UploadFile = File(...)):
# 保存上传文件
with tempfile.NamedTemporaryFile(suffix=".pdf", delete=False) as tmp:
content = await file.read()
tmp.write(content)
tmp_path = tmp.name
# 执行推理
results = model.predict(tmp_path, conf=0.5)
# 返回结果
return {
"fields": extract_fields(results),
"confidence": get_confidence(results)
}
@app.get("/health")
async def health():
return {"status": "healthy"}
```
### 部署命令
```bash
# 1. 创建 Container Registry
az acr create --name invoiceacr --resource-group myRG --sku Basic
# 2. 构建并推送镜像
az acr build --registry invoiceacr --image invoice-inference:v1 .
# 3. 创建 Container Apps 环境
az containerapp env create \
--name invoice-env \

--ingress external --target-port 8000
# 5. 获取 URL
az containerapp show --name invoice-inference --resource-group myRG --query properties.configuration.ingress.fqdn
```
### 高吞吐场景: Serverless GPU
如果需要 GPU 加速推理（高并发、低延迟）：
```bash
# 请求 GPU 配额
az containerapp env workload-profile add \
--name invoice-env \
--resource-group myRG \
--workload-profile-name gpu \
--workload-profile-type Consumption-GPU-T4
# 部署 GPU 版本
az containerapp create \
--name invoice-inference-gpu \
--resource-group myRG \
--environment invoice-env \
--image invoiceacr.azurecr.io/invoice-inference-gpu:v1 \
--workload-profile-name gpu \
--cpu 4 --memory 8Gi \
--min-replicas 0 --max-replicas 5 \
--ingress external --target-port 8000
```
### 推理性能对比

| 训练服务 | Azure ML (min=0, Spot) | 按需 ~$1-5/次 |
| Container Registry | Basic | ~$5 |
| **总计** | | **~$65/月** + 训练费 |
### 关键决策
| 场景 | 选择 |
|------|------|
| 偶尔训练，简单需求 | Azure VM Spot + 手动启停 |
| 需要 MLOps，团队协作 | Azure ML Compute |
| 追求最低空闲成本 | Container Apps Serverless GPU |
| 生产环境推理 | Container Apps CPU |
| 高并发推理 | Container Apps Serverless GPU |
### 注意事项
1. **冷启动**: Serverless GPU 启动需要 3-8 分钟
2. **Spot 中断**: 可能被抢占，需要检查点机制
3. **网络延迟**: Blob Storage 挂载比本地 SSD 慢，建议开启缓存
4. **区域选择**: 选择有 GPU 配额的区域 (East US, West Europe 等)
5. **推理优化**: CPU 推理对于 YOLO 已经足够，无需 GPU

});
};
// useActiveModel
const useActiveModel = () => {
return useQuery({

});
};
// useRecentActivity
const useRecentActivity = (limit = 10) => {

queryKey: ['dashboard', 'activity', limit],
queryFn: () => api.get(`/admin/dashboard/activity?limit=${limit}`),
refetchInterval: 30000,
});
};
```

## 6. Annotation Completeness Definition
### 6.1 Core Fields
A document is **complete** when it has annotations for:
| Requirement | Fields | Logic |
|-------------|--------|-------|
| Identifier | `invoice_number` (class_id=0) OR `ocr_number` (class_id=3) | At least one |
| Payment Account | `bankgiro` (class_id=4) OR `plusgiro` (class_id=5) | At least one |
### 6.2 Status Categories
| Category | Criteria |
|----------|----------|
| **Complete** | status=labeled AND has identifier AND has payment account |
| **Incomplete** | status=labeled AND (missing identifier OR missing payment account) |
| **Pending** | status IN (pending, auto_labeling) |
### 6.3 Filter Implementation
```sql
-- Complete documents
WHERE status = 'labeled'
AND document_id IN (
SELECT document_id FROM admin_annotations WHERE class_id IN (0, 3)
)
AND document_id IN (
SELECT document_id FROM admin_annotations WHERE class_id IN (4, 5)
)
-- Incomplete documents
WHERE status = 'labeled'
AND (
document_id NOT IN (
SELECT document_id FROM admin_annotations WHERE class_id IN (0, 3)
)
OR document_id NOT IN (
SELECT document_id FROM admin_annotations WHERE class_id IN (4, 5)
)
)
```

# 多池处理架构设计文档
## 1. 研究总结
### 1.1 当前问题分析
我们之前实现的双池模式存在稳定性问题，主要原因：
| 问题 | 原因 | 解决方案 |
|------|------|----------|
| 处理卡住 | 线程 + ProcessPoolExecutor 混用导致死锁 | 使用 asyncio 或纯 Queue 模式 |
| Queue.get() 无限阻塞 | 没有超时机制 | 添加 timeout 和哨兵值 |
| GPU 内存冲突 | 多进程同时访问 GPU | 限制 GPU worker = 1 |
| CUDA fork 问题 | Linux 默认 fork 不兼容 CUDA | 使用 spawn 启动方式 |
### 1.2 推荐架构方案
经过研究，最适合我们场景的方案是 **生产者-消费者队列模式**：
```
┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐
│ Main Process │ │ CPU Workers │ │ GPU Worker │
│ │ │ (4 processes) │ │ (1 process) │
│ ┌───────────┐ │ │ │ │ │
│ │ Task │──┼────▶│ Text PDF处理 │ │ Scanned PDF处理 │
│ │ Dispatcher│ │ │ (无需OCR) │ │ (PaddleOCR) │
│ └───────────┘ │ │ │ │ │
│ ▲ │ │ │ │ │ │ │
│ │ │ │ ▼ │ │ ▼ │
│ ┌───────────┐ │ │ Result Queue │ │ Result Queue │
│ │ Result │◀─┼─────│◀────────────────│─────│◀────────────────│
│ │ Collector │ │ │ │ │ │
│ └───────────┘ │ └─────────────────┘ └─────────────────┘
│ │ │
│ ▼ │
│ ┌───────────┐ │
│ │ Database │ │
│ │ Batch │ │
│ │ Writer │ │
│ └───────────┘ │
└─────────────────┘
```
---
## 2. 核心设计原则
### 2.1 CUDA 兼容性
```python
# 关键：使用 spawn 启动方式
import multiprocessing as mp
ctx = mp.get_context("spawn")
# GPU worker 初始化时设置设备
def init_gpu_worker(gpu_id: int = 0):
os.environ["CUDA_VISIBLE_DEVICES"] = str(gpu_id)
global _ocr
from paddleocr import PaddleOCR
_ocr = PaddleOCR(use_gpu=True, ...)
```
### 2.2 Worker 初始化模式
使用 `initializer` 参数一次性加载模型，避免每个任务重新加载：
```python
# 全局变量保存模型
_ocr = None
def init_worker(use_gpu: bool, gpu_id: int = 0):
global _ocr
if use_gpu:
os.environ["CUDA_VISIBLE_DEVICES"] = str(gpu_id)
else:
os.environ["CUDA_VISIBLE_DEVICES"] = "-1"
from paddleocr import PaddleOCR
_ocr = PaddleOCR(use_gpu=use_gpu, ...)
# 创建 Pool 时使用 initializer
pool = ProcessPoolExecutor(
max_workers=1,
initializer=init_worker,
initargs=(True, 0), # use_gpu=True, gpu_id=0
mp_context=mp.get_context("spawn")
)
```
### 2.3 队列模式 vs as_completed
| 方式 | 优点 | 缺点 | 适用场景 |
|------|------|------|----------|
| `as_completed()` | 简单、无需管理队列 | 无法跨多个 Pool 使用 | 单池场景 |
| `multiprocessing.Queue` | 高性能、灵活 | 需要手动管理、死锁风险 | 多池流水线 |
| `Manager().Queue()` | 可 pickle、跨 Pool | 性能较低 | 需要 Pool.map 场景 |
**推荐**：对于双池场景，使用 `as_completed()` 分别处理每个池，然后合并结果。
---
## 3. 详细开发计划
### 阶段 1：重构基础架构 (2-3天)
#### 1.1 创建 WorkerPool 抽象类
```python
# src/processing/worker_pool.py
from __future__ import annotations
from abc import ABC, abstractmethod
from concurrent.futures import ProcessPoolExecutor, Future
from dataclasses import dataclass
from typing import List, Any, Optional, Callable
import multiprocessing as mp
@dataclass
class TaskResult:
"""任务结果容器"""
task_id: str
success: bool
data: Any
error: Optional[str] = None
processing_time: float = 0.0
class WorkerPool(ABC):
"""Worker Pool 抽象基类"""
def __init__(self, max_workers: int, use_gpu: bool = False, gpu_id: int = 0):
self.max_workers = max_workers
self.use_gpu = use_gpu
self.gpu_id = gpu_id
self._executor: Optional[ProcessPoolExecutor] = None
@abstractmethod
def get_initializer(self) -> Callable:
"""返回 worker 初始化函数"""
pass
@abstractmethod
def get_init_args(self) -> tuple:
"""返回初始化参数"""
pass
def start(self):
"""启动 worker pool"""
ctx = mp.get_context("spawn")
self._executor = ProcessPoolExecutor(
max_workers=self.max_workers,
mp_context=ctx,
initializer=self.get_initializer(),
initargs=self.get_init_args()
)
def submit(self, fn: Callable, *args, **kwargs) -> Future:
"""提交任务"""
if not self._executor:
raise RuntimeError("Pool not started")
return self._executor.submit(fn, *args, **kwargs)
def shutdown(self, wait: bool = True):
"""关闭 pool"""
if self._executor:
self._executor.shutdown(wait=wait)
self._executor = None
def __enter__(self):
self.start()
return self
def __exit__(self, *args):
self.shutdown()
```
#### 1.2 实现 CPU 和 GPU Worker Pool
```python
# src/processing/cpu_pool.py
class CPUWorkerPool(WorkerPool):
"""CPU-only worker pool for text PDF processing"""
def __init__(self, max_workers: int = 4):
super().__init__(max_workers=max_workers, use_gpu=False)
def get_initializer(self) -> Callable:
return init_cpu_worker
def get_init_args(self) -> tuple:
return ()
# src/processing/gpu_pool.py
class GPUWorkerPool(WorkerPool):
"""GPU worker pool for OCR processing"""
def __init__(self, max_workers: int = 1, gpu_id: int = 0):
super().__init__(max_workers=max_workers, use_gpu=True, gpu_id=gpu_id)
def get_initializer(self) -> Callable:
return init_gpu_worker
def get_init_args(self) -> tuple:
return (self.gpu_id,)
```
---
### 阶段 2：实现双池协调器 (2-3天)
#### 2.1 任务分发器
```python
# src/processing/task_dispatcher.py
from dataclasses import dataclass
from enum import Enum, auto
from typing import List, Tuple
class TaskType(Enum):
CPU = auto() # Text PDF
GPU = auto() # Scanned PDF
@dataclass
class Task:
id: str
task_type: TaskType
data: Any
class TaskDispatcher:
"""根据 PDF 类型分发任务到不同的 pool"""
def classify_task(self, doc_info: dict) -> TaskType:
"""判断文档是否需要 OCR"""
# 基于 PDF 特征判断
if self._is_scanned_pdf(doc_info):
return TaskType.GPU
return TaskType.CPU
def _is_scanned_pdf(self, doc_info: dict) -> bool:
"""检测是否为扫描件"""
# 1. 检查是否有可提取文本
# 2. 检查图片比例
# 3. 检查文本密度
pass
def partition_tasks(self, tasks: List[Task]) -> Tuple[List[Task], List[Task]]:
"""将任务分为 CPU 和 GPU 两组"""
cpu_tasks = [t for t in tasks if t.task_type == TaskType.CPU]
gpu_tasks = [t for t in tasks if t.task_type == TaskType.GPU]
return cpu_tasks, gpu_tasks
```
#### 2.2 双池协调器
```python
# src/processing/dual_pool_coordinator.py
from concurrent.futures import as_completed
from typing import List, Iterator
import logging
logger = logging.getLogger(__name__)
class DualPoolCoordinator:
"""协调 CPU 和 GPU 两个 worker pool"""
def __init__(
self,
cpu_workers: int = 4,
gpu_workers: int = 1,
gpu_id: int = 0
):
self.cpu_pool = CPUWorkerPool(max_workers=cpu_workers)
self.gpu_pool = GPUWorkerPool(max_workers=gpu_workers, gpu_id=gpu_id)
self.dispatcher = TaskDispatcher()
def __enter__(self):
self.cpu_pool.start()
self.gpu_pool.start()
return self
def __exit__(self, *args):
self.cpu_pool.shutdown()
self.gpu_pool.shutdown()
def process_batch(
self,
documents: List[dict],
cpu_task_fn: Callable,
gpu_task_fn: Callable,
on_result: Optional[Callable[[TaskResult], None]] = None,

Task(id=doc['id'], task_type=self.dispatcher.classify_task(doc), data=doc)
for doc in documents
]
cpu_tasks, gpu_tasks = self.dispatcher.partition_tasks(tasks)
logger.info(f"Task partition: {len(cpu_tasks)} CPU, {len(gpu_tasks)} GPU")

if on_error:
on_error(task_id, e)
results.append(result)
return results
```
---
### 阶段 3：集成到 autolabel (1-2天)
#### 3.1 修改 autolabel.py
```python
# src/cli/autolabel.py
def run_autolabel_dual_pool(args):
"""使用双池模式运行自动标注"""
from src.processing.dual_pool_coordinator import DualPoolCoordinator
# 初始化数据库批处理
db_batch = []
db_batch_size = 100
def on_result(result: TaskResult):
"""处理成功结果"""
nonlocal db_batch
db_batch.append(result.data)
if len(db_batch) >= db_batch_size:
save_documents_batch(db_batch)
db_batch.clear()
def on_error(task_id: str, error: Exception):
"""处理错误"""
logger.error(f"Task {task_id} failed: {error}")
# 创建双池协调器
with DualPoolCoordinator(
cpu_workers=args.cpu_workers or 4,
gpu_workers=args.gpu_workers or 1,
gpu_id=0
) as coordinator:
# 处理所有 CSV
for csv_file in csv_files:
documents = load_documents_from_csv(csv_file)
results = coordinator.process_batch(
documents=documents,
cpu_task_fn=process_text_pdf,
gpu_task_fn=process_scanned_pdf,
on_result=on_result,
on_error=on_error
)
logger.info(f"CSV {csv_file}: {len(results)} processed")
# 保存剩余批次
if db_batch:
save_documents_batch(db_batch)
```
---
### 阶段 4：测试与验证 (1-2天)
#### 4.1 单元测试
```python
# tests/unit/test_dual_pool.py
import pytest
from src.processing.dual_pool_coordinator import DualPoolCoordinator, TaskResult
class TestDualPoolCoordinator:
def test_cpu_only_batch(self):
"""测试纯 CPU 任务批处理"""
with DualPoolCoordinator(cpu_workers=2, gpu_workers=1) as coord:
docs = [{"id": f"doc_{i}", "type": "text"} for i in range(10)]
results = coord.process_batch(docs, cpu_fn, gpu_fn)
assert len(results) == 10
assert all(r.success for r in results)
def test_mixed_batch(self):
"""测试混合任务批处理"""
with DualPoolCoordinator(cpu_workers=2, gpu_workers=1) as coord:
docs = [
{"id": "text_1", "type": "text"},
{"id": "scan_1", "type": "scanned"},
{"id": "text_2", "type": "text"},
]
results = coord.process_batch(docs, cpu_fn, gpu_fn)
assert len(results) == 3
def test_timeout_handling(self):
"""测试超时处理"""
pass
def test_error_recovery(self):
"""测试错误恢复"""
pass
```
#### 4.2 集成测试
```python
# tests/integration/test_autolabel_dual_pool.py
def test_autolabel_with_dual_pool():
"""端到端测试双池模式"""
# 使用少量测试数据
result = subprocess.run([
"python", "-m", "src.cli.autolabel",
"--cpu-workers", "2",
"--gpu-workers", "1",
"--limit", "50"
], capture_output=True)
assert result.returncode == 0
# 验证数据库记录
```
---
## 4. 关键技术点
### 4.1 避免死锁的策略
```python
# 1. 使用 timeout
try:
result = future.result(timeout=300)
except TimeoutError:
logger.warning(f"Task timed out")
# 2. 使用哨兵值
SENTINEL = object()
queue.put(SENTINEL) # 发送结束信号
# 3. 检查进程状态
if not worker.is_alive():
logger.error("Worker died unexpectedly")
break
# 4. 先清空队列再 join
while not queue.empty():
results.append(queue.get_nowait())
worker.join(timeout=5.0)
```
### 4.2 PaddleOCR 特殊处理
```python
# PaddleOCR 必须在 worker 进程中初始化
def init_paddle_worker(gpu_id: int):
global _ocr
import os
os.environ["CUDA_VISIBLE_DEVICES"] = str(gpu_id)
# 延迟导入，确保 CUDA 环境变量生效
from paddleocr import PaddleOCR
_ocr = PaddleOCR(
use_angle_cls=True,
lang='en',
use_gpu=True,
show_log=False,
# 重要：设置 GPU 内存比例
gpu_mem=2000 # 限制 GPU 内存使用 (MB)
)
```
### 4.3 资源监控
```python
import psutil
import GPUtil
def get_resource_usage():
"""获取系统资源使用情况"""
cpu_percent = psutil.cpu_percent(interval=1)
memory = psutil.virtual_memory()
gpu_info = []
for gpu in GPUtil.getGPUs():
gpu_info.append({
"id": gpu.id,
"memory_used": gpu.memoryUsed,
"memory_total": gpu.memoryTotal,
"utilization": gpu.load * 100
})
return {
"cpu_percent": cpu_percent,
"memory_percent": memory.percent,
"gpu": gpu_info
}
```
---
## 5. 风险评估与应对
| 风险 | 可能性 | 影响 | 应对策略 |
|------|--------|------|----------|
| GPU 内存不足 | 中 | 高 | 限制 GPU worker = 1，设置 gpu_mem 参数 |
| 进程僵死 | 低 | 高 | 添加心跳检测，超时自动重启 |
| 任务分类错误 | 中 | 中 | 添加回退机制，CPU 失败后尝试 GPU |
| 数据库写入瓶颈 | 低 | 中 | 增大批处理大小，异步写入 |
---
## 6. 备选方案
如果上述方案仍存在问题，可以考虑：
### 6.1 使用 Ray
```python
import ray
ray.init()
@ray.remote(num_cpus=1)
def cpu_task(data):
return process_text_pdf(data)
@ray.remote(num_gpus=1)
def gpu_task(data):
return process_scanned_pdf(data)
# 自动资源调度
futures = [cpu_task.remote(d) for d in cpu_docs]
futures += [gpu_task.remote(d) for d in gpu_docs]
results = ray.get(futures)
```
### 6.2 单池 + 动态 GPU 调度
保持单池模式，但在每个任务内部动态决定是否使用 GPU：
```python
def process_document(doc_data):
if is_scanned_pdf(doc_data):
# 使用 GPU (需要全局锁或信号量控制并发)
with gpu_semaphore:
return process_with_ocr(doc_data)
else:
return process_text_only(doc_data)
```
---
## 7. 时间线总结
| 阶段 | 任务 | 预计工作量 |
|------|------|------------|
| 阶段 1 | 基础架构重构 | 2-3 天 |
| 阶段 2 | 双池协调器实现 | 2-3 天 |
| 阶段 3 | 集成到 autolabel | 1-2 天 |
| 阶段 4 | 测试与验证 | 1-2 天 |
| **总计** | | **6-10 天** |

## Import Examples
### Old Import Style (Before Refactoring)
```python
from src.web.admin_routes import create_admin_router
from src.web.admin_schemas import DocumentItem
from src.web.admin_auth import validate_admin_token
from src.web.async_routes import create_async_router
from src.web.schemas import ErrorResponse
```
### New Import Style (After Refactoring)
```python
# Admin API
from src.web.api.v1.admin.documents import create_admin_router
from src.web.api.v1.admin import create_admin_router # Shorter alternative
# Schemas
from src.web.schemas.admin import DocumentItem
from src.web.schemas.common import ErrorResponse
# Core components
from src.web.core.auth import validate_admin_token
# Async API
from src.web.api.v1.async_api.routes import create_async_router
```
---
## Benefits Achieved
### 1. **Clear Separation of Concerns**
- **API Routes**: All in `api/v1/` by version and feature
- **Data Models**: All in `schemas/` by domain
- **Business Logic**: All in `services/`
- **Core Components**: Reusable utilities in `core/`
- **Background Jobs**: Task queues in `workers/`
### 2. **Better Scalability**
- Easy to add API v2 without touching v1
- Clear namespace for each module
- Reduced file sizes (no 800+ line files)
- Follows single responsibility principle
### 3. **Improved Maintainability**
- Find files by function, not by prefix
- Each module has one clear purpose
- Easier to onboard new developers
- Better IDE navigation
### 4. **Standards Compliance**
- Follows FastAPI best practices
- Matches Django/Flask project structures
- Standard Python package organization
- Industry-standard naming conventions

# Web Directory Refactoring Plan
## Current Structure Issues
1. **Flat structure**: All files in one directory (20 Python files)
2. **Naming inconsistency**: Mix of `admin_*`, `async_*`, `batch_*` prefixes
3. **Mixed concerns**: Routes, schemas, services, and workers in same directory
4. **Poor scalability**: Hard to navigate and maintain as project grows
## Proposed Structure (Best Practices)

## Benefits
### 1. Clear Separation of Concerns
- **Routes**: API endpoint definitions
- **Schemas**: Data validation models
- **Services**: Business logic
- **Core**: Reusable components
- **Workers**: Background processing
### 2. Better Scalability
- Easy to add new API versions (`v2/`)
- Clear namespace for each domain
- Reduced file size (no 800+ line files)
### 3. Improved Maintainability
- Find files by function, not by prefix
- Each module has single responsibility
- Easier to write focused tests
### 4. Standard Python Patterns
- Package-based organization
- Follows FastAPI best practices
- Similar to Django/Flask structures
## Implementation Steps
### Phase 1: Create New Structure (No Breaking Changes)
1. Create new directories: `api/`, `schemas/`, `services/`, `core/`, `workers/`
2. Copy files to new locations (don't delete originals yet)
3. Update imports in new files
4. Add `__init__.py` with proper exports
### Phase 2: Update Tests
5. Update test imports to use new structure
6. Run tests to verify nothing breaks
7. Fix any import issues
### Phase 3: Update Main App
8. Update `app.py` to import from new locations
9. Run full test suite
10. Verify all endpoints work
### Phase 4: Cleanup
11. Delete old files
12. Update documentation
13. Final test run
## Migration Priority
**High Priority** (Most used):
- Routes and schemas (user-facing APIs)
- Services (core business logic)
**Medium Priority**:
- Core components (auth, rate limiter)
- Workers (background tasks)
**Low Priority**:
- Config and dependencies (already well-located)
## Backwards Compatibility
During migration, maintain backwards compatibility:
```python
# src/web/__init__.py
# Old imports still work
from src.web.api.v1.admin.documents import router as admin_router
from src.web.schemas.admin import AdminDocument
# Keep old names for compatibility (temporary)
admin_routes = admin_router # Deprecated alias
```
## Testing Strategy
1. **Unit Tests**: Test each module independently
2. **Integration Tests**: Test API endpoints still work
3. **Import Tests**: Verify all old imports still work
4. **Coverage**: Maintain current 23% coverage minimum
## Rollback Plan
If issues arise:
1. Keep old files until fully migrated
2. Git allows easy revert
3. Tests catch breaking changes early
---
## Next Steps
Would you like me to:
1. **Start Phase 1**: Create new directory structure and move files?
2. **Create migration script**: Automate the file moves and import updates?
3. **Focus on specific area**: Start with admin API or async API first?

---
## ⏳ Remaining Work
### 1. Update Remaining File Imports (HIGH PRIORITY)
Files that need import updates:
- [ ] `api/v1/batch/routes.py` - update to use new schema/service imports
- [ ] `services/autolabel.py` - may need import updates if it references old paths
- [ ] `services/async_processing.py` - check for old import references
- [ ] `services/batch_upload.py` - check for old import references
- [ ] `services/inference.py` - check for old import references
### 2. Update ALL Test Files (CRITICAL)
Test files need to import from new locations. Pattern:
**Old:**
```python
from src.web.admin_routes import create_admin_router
from src.web.admin_schemas import DocumentItem
from src.web.admin_auth import validate_admin_token
```
**New:**
```python
from src.web.api.v1.admin import create_admin_router
from src.web.schemas.admin import DocumentItem
from src.web.core.auth import validate_admin_token
```
Test files to update:
- [ ] `tests/web/test_admin_annotations.py`
- [ ] `tests/web/test_admin_auth.py`
- [ ] `tests/web/test_admin_routes.py`
- [ ] `tests/web/test_admin_routes_enhanced.py`
- [ ] `tests/web/test_admin_training.py`
- [ ] `tests/web/test_annotation_locks.py`
- [ ] `tests/web/test_annotation_phase5.py`
- [ ] `tests/web/test_async_queue.py`
- [ ] `tests/web/test_async_routes.py`
- [ ] `tests/web/test_async_service.py`
- [ ] `tests/web/test_autolabel_with_locks.py`
- [ ] `tests/web/test_batch_queue.py`
- [ ] `tests/web/test_batch_upload_routes.py`
- [ ] `tests/web/test_batch_upload_service.py`
- [ ] `tests/web/test_rate_limiter.py`
- [ ] `tests/web/test_training_phase4.py`
### 3. Create Backward Compatibility Layer (OPTIONAL)
Keep old imports working temporarily:
```python
# src/web/admin_routes.py (temporary compatibility shim)
\"\"\"
DEPRECATED: Use src.web.api.v1.admin.documents instead.
This file will be removed in next version.
\"\"\"
import warnings
from src.web.api.v1.admin.documents import *
warnings.warn(
"Importing from src.web.admin_routes is deprecated. "
"Use src.web.api.v1.admin.documents instead.",
DeprecationWarning,
stacklevel=2
)
```
### 4. Verify and Test
1. Run tests:
```bash
pytest tests/web/ -v
```
2. Check for any import errors:
```bash
python -c "from src.web.app import create_app; create_app()"
```
3. Start server and test endpoints:
```bash
python run_server.py
```
### 5. Clean Up Old Files (ONLY AFTER TESTS PASS)
Old files to remove:
- `src/web/admin_*.py` (7 files)
- `src/web/async_*.py` (3 files)
- `src/web/batch_*.py` (3 files)
- `src/web/routes.py`
- `src/web/services.py`
- `src/web/schemas.py`
- `src/web/rate_limiter.py`
Keep these files (don't remove):
- `src/web/__init__.py`
- `src/web/app.py`
- `src/web/config.py`
- `src/web/dependencies.py`
---
## 🎯 Next Immediate Steps
1. **Update batch/routes.py imports** - Quick fix for remaining API route
2. **Update test file imports** - Critical for verification
3. **Run test suite** - Verify nothing broke
4. **Fix any import errors** - Address failures
5. **Remove old files** - Clean up after tests pass
---
## 📊 Migration Impact Summary
| Category | Files Moved | Imports Updated | Status |
|----------|-------------|-----------------|--------|
| API Routes | 7 | 5/7 | 🟡 In Progress |
| Schemas | 3 | 3/3 | ✅ Complete |
| Services | 4 | 0/4 | ⚠️ Pending |
| Core | 3 | 3/3 | ✅ Complete |
| Workers | 2 | 2/2 | ✅ Complete |
| Tests | 0 | 0/16 | ❌ Not Started |
**Overall Progress: 65%**
---
## 🚀 Benefits After Migration
1. **Better Organization**: Clear separation by function
2. **Easier Navigation**: Find files by purpose, not prefix
3. **Scalability**: Easy to add new API versions
4. **Standard Structure**: Follows FastAPI best practices
5. **Maintainability**: Each module has single responsibility
---
## 📝 Notes
- All original files are still in place (no data loss risk)
- New structure is operational but needs import updates
- Backward compatibility can be added if needed
- Tests will validate the migration success

# Frontend Refactoring Plan
## Current Structure Issues
1. **Flat component organization** - All components in one directory
2. **Mock data only** - No real API integration
3. **No state management** - Props drilling everywhere
4. **CDN dependencies** - Should use npm packages
5. **Manual routing** - Using useState instead of react-router
6. **No TypeScript integration with backend** - Types don't match API schemas
## Recommended Structure

## Migration Steps
### Phase 1: Setup Infrastructure
- [ ] Install dependencies (axios, react-router, zustand, @tanstack/react-query)
- [ ] Setup local Tailwind (remove CDN)
- [ ] Create API client with interceptors
- [ ] Add environment variables (.env.local with VITE_API_URL)
### Phase 2: Create API Layer
- [ ] Create `src/api/client.ts` with axios instance
- [ ] Create `src/api/endpoints/documents.ts` matching backend API
- [ ] Create `src/api/endpoints/annotations.ts`
- [ ] Create `src/api/endpoints/training.ts`
- [ ] Add types matching backend schemas
### Phase 3: Reorganize Components
- [ ] Move existing components to new structure
- [ ] Split large components (Dashboard > DocumentTable + DocumentFilters + DocumentRow)
- [ ] Extract reusable components (Badge, Button already done)
- [ ] Create layout components (TopNav, Sidebar)
### Phase 4: Add Routing
- [ ] Install react-router-dom
- [ ] Create router.tsx with routes
- [ ] Update App.tsx to use RouterProvider
- [ ] Add navigation links
### Phase 5: State Management
- [ ] Create custom hooks (useDocuments, useAnnotations)
- [ ] Use @tanstack/react-query for server state
- [ ] Add Zustand stores for UI state
- [ ] Replace mock data with API calls
### Phase 6: Backend Integration
- [ ] Update CORS settings in backend
- [ ] Test all API endpoints
- [ ] Add error handling
- [ ] Add loading states
## Dependencies to Add
```json
{
"dependencies": {
"react-router-dom": "^6.22.0",
"axios": "^1.6.7",
"zustand": "^4.5.0",
"@tanstack/react-query": "^5.20.0",
"date-fns": "^3.3.0",
"clsx": "^2.1.0"
},
"devDependencies": {
"tailwindcss": "^3.4.1",
"autoprefixer": "^10.4.17",
"postcss": "^8.4.35"
}
}
```
## Configuration Files to Create
### tailwind.config.js
```javascript
export default {
content: ['./index.html', './src/**/*.{js,ts,jsx,tsx}'],
theme: {
extend: {
colors: {
warm: {
bg: '#FAFAF8',
card: '#FFFFFF',
hover: '#F1F0ED',
selected: '#ECEAE6',
border: '#E6E4E1',
divider: '#D8D6D2',
text: {
primary: '#121212',
secondary: '#2A2A2A',
muted: '#6B6B6B',
disabled: '#9A9A9A',
},
state: {
success: '#3E4A3A',
error: '#4A3A3A',
warning: '#4A4A3A',
info: '#3A3A3A',
}
}
}
}
}
}
```
### .env.example
```bash
VITE_API_URL=http://localhost:8000
VITE_WS_URL=ws://localhost:8000/ws
```
## Type Generation from Backend
Consider generating TypeScript types from Python Pydantic schemas:
- Option 1: Use `datamodel-code-generator` to convert schemas
- Option 2: Manually maintain types in `src/types/api.ts`
- Option 3: Use OpenAPI spec + openapi-typescript-codegen
## Testing Strategy
- Unit tests: Vitest for components
- Integration tests: React Testing Library
- E2E tests: Playwright (matching backend)
## Performance Considerations
- Code splitting by route
- Lazy load heavy components (AnnotationCanvas)
- Optimize re-renders with React.memo
- Use virtual scrolling for large tables
- Image lazy loading for document previews
## Accessibility
- Proper ARIA labels
- Keyboard navigation
- Focus management
- Color contrast compliance (already done with Warm Graphite theme)

## Key Technologies
- **React 19** - UI framework
- **TypeScript** - Type safety
- **Vite** - Build tool
- **Tailwind CSS** - Styling (Warm Graphite theme)
- **Axios** - HTTP client
- **@tanstack/react-query** - Server state management
- **lucide-react** - Icon library
## API Integration
### Authentication
The app stores admin token in localStorage:
```typescript
localStorage.setItem('admin_token', 'your-token')
```
All API requests automatically include the `X-Admin-Token` header.
### Available Hooks
#### useDocuments
```typescript
const {
documents,
total,
isLoading,
uploadDocument,
deleteDocument,
triggerAutoLabel,
} = useDocuments({ status: 'labeled', limit: 20 })
```
#### useDocumentDetail
```typescript
const { document, annotations, isLoading } = useDocumentDetail(documentId)
```
#### useAnnotations
```typescript
const {
createAnnotation,
updateAnnotation,
deleteAnnotation,
verifyAnnotation,
overrideAnnotation,
} = useAnnotations(documentId)
```
#### useTraining
```typescript
const {
models,
isLoadingModels,
startTraining,
downloadModel,
} = useTraining()
```
## Features Implemented
### Phase 1 (Completed)
- ✅ API client with axios interceptors
- ✅ Type-safe API endpoints
- ✅ React Query for server state
- ✅ Custom hooks for all APIs
- ✅ Dashboard with real data
- ✅ Local Tailwind CSS
- ✅ Environment configuration
- ✅ CORS configured in backend
### Phase 2 (TODO)
- [ ] Update DocumentDetail to use useDocumentDetail
- [ ] Update Training page to use useTraining hooks
- [ ] Update Models page with real data
- [ ] Add UploadModal integration with API
- [ ] Add react-router for proper routing
- [ ] Add error boundary
- [ ] Add loading states
- [ ] Add toast notifications
### Phase 3 (TODO)
- [ ] Annotation canvas with real data
- [ ] Batch upload functionality
- [ ] Auto-label progress polling
- [ ] Training job monitoring
- [ ] Model download functionality
- [ ] Search and filtering
- [ ] Pagination
## Development Tips
### Hot Module Replacement
Vite supports HMR. Changes will reflect immediately without page reload.
### API Debugging
Check browser console for API requests:
- Network tab shows all requests/responses
- Axios interceptors log errors automatically
### Type Safety
TypeScript types in `src/api/types.ts` match backend Pydantic schemas.
To regenerate types from backend:
```bash
# TODO: Add type generation script
```
### Backend API Documentation
Visit http://localhost:8000/docs for interactive API documentation (Swagger UI).
## Troubleshooting
### CORS Errors
If you see CORS errors:
1. Check backend is running at http://localhost:8000
2. Verify CORS settings in `src/web/app.py`
3. Check `.env.local` has correct `VITE_API_URL`
### Module Not Found
If imports fail:
```bash
rm -rf node_modules package-lock.json
npm install
```
### Types Not Matching
If API responses don't match types:
1. Check backend version is up-to-date
2. Verify types in `src/api/types.ts`
3. Check API response in Network tab
## Next Steps
1. Run `npm install` to install dependencies
2. Start backend server
3. Run `npm run dev` to start frontend
4. Open http://localhost:3000
5. Create an admin token via backend API
6. Store token in localStorage via browser console:
```javascript
localStorage.setItem('admin_token', 'your-token-here')
```
7. Refresh page to see authenticated API calls
## Production Build
```bash
npm run build
npm run preview # Preview production build
```
Build output will be in `dist/` directory.
