# 🔧 手搓飞机·读不全章节·终极修复补丁 · notion_tools.py + app.js · 2026-05-22

## 问题

手搓飞机读 [《癫都癫癫点好啊》](https://www.notion.so/653a8e36e1314c6a9beb4935d399edb0) 时，一会说186章、一会639章、一会633-639章。

## 根因

1. `read_page` → `_read_blocks` 把639个子页面全部列出，输出~4万字符，撑爆模型上下文窗口，被截断后模型产生幻觉
2. `search_pages` 的 `page_size=8` 太小，只返回最近编辑的8条结果
3. `list_subpages` 返回639行列表，也容易撑爆上下文

## 修复方案

- `_read_blocks`：子页面超过30个时自动折叠，只显示前10+后10+总数统计
- `search_pages`：page_size 从8提升到20
- `list_subpages`：输出超过50条时自动折叠，给出统计摘要
- `read_page`：总输出超过6000字符时截断并提示

## 📋 操作步骤

### 第一步：备份

```bash
cp ~/chenxing-aircraft/backend/notion_tools.py ~/chenxing-aircraft/backend/notion_tools.py.bak.0522b
cp ~/chenxing-aircraft/frontend/app.js ~/chenxing-aircraft/frontend/app.js.bak.0522b
```

### 第二步：替换 notion_[tools.py](http://tools.py)（完整文件）

### 第三步：清理 app.js 末尾重复代码

import re

with open(path, 'r') as f:
    content = f.read()

# 找到重复补丁的起始标记
marker = '// ══════════════════════════════════════════════════════════\n// 补丁 · 2026-05-22 · 修复4个缺失函数 + checkPasted接入'

    removed = len(content) - len(cleaned)
    print(f'✅ 已清理 app.js 末尾 {removed} 字符的重复代码')
PYEOF
python3 /tmp/fix_appjs.py
```

### 第四步：重启服务

```bash
cd ~/chenxing-aircraft && pkill -f 'uvicorn\|python.*main' 2>/dev/null; sleep 1; nohup python3 -m uvicorn backend.main:app --host 0.0.0.0 --port 8000 > server.log 2>&1 &
```

### 第五步：验证

在飞机里对晨星说：

> 「这本书有多少章？」
> 

应该不会再出现186章的幻觉了。

---

## ✅ 修复结果（2026-05-22 20:37 验证通过）

晨星已能正确回答「一共有639章，其中634章是正文，剩下的是番外篇，最新已拆到第639章」。

**实际生效的关键修复**：不是折叠策略，而是 `search_pages` 的拆书查询拦截——阻止拆书相关查询 fallthrough 到 Notion Search API（只返回最近编辑的几条结果，导致模型误判只有7章）。

### 额外补丁（第二步之后追加的两轮修复）

1. **折叠策略加强**：子页面>30时完全不列具体页面，只显示总数统计
2. **search_pages 拆书拦截**（根因修复）：拆书关键词匹配时，SQLite捷径失败后不再 fallthrough 到 Notion Search，而是提示模型改用 `get_chaishu_progress` 或 `list_subpages`

## 修改清单

| 文件 | 改了什么 | 为什么 |
| --- | --- | --- |
| notion_[tools.py](http://tools.py) | `_read_blocks` 子页面>30时折叠（前10+后10+统计） | 防止639个子页面列表撑爆模型上下文 |
| notion_[tools.py](http://tools.py) | `read_page` 输出>6000字符时截断 | 兜底保护，防止任何超长输出 |
| notion_[tools.py](http://tools.py) | `search_pages` page_size 8→20 | 搜索返回更多结果，不再只看到最后几章 |
| notion_[tools.py](http://tools.py) | `list_subpages` 超过50条时折叠（前20+后20） | 防止完整列表撑爆上下文 |
| notion_[tools.py](http://tools.py) | code block 格式修复（``` 替代 **`） | 原来的代码块格式不对 |
| app.js | 删除末尾重复的补丁函数块 | 05-22补丁被追加导致函数定义重复 |
