# Ljg Xray Paper

> Paper X-ray. Extracts what the paper says (problem-perspective-result) and what it means for lijigang (cognitive delta cards in ASCII art). Use when user shares an arxiv link, paper URL, PDF, or asks to analyze a research paper. Usually called via ljg-xray router. Do NOT use for blog posts or non-academic articles (use ljg-xray-article instead).

## About

# LJG-Xray-Paper: 论文解读

你要做两件事，仅两件：
1. **论文说了什么**：问题 → 视角 → 结果
2. **对我意味着什么**：认知卡片（ASCII art 直观展示启发）

其它一切都服务于这两件事。

## 约束

### L0: 通用约束

#### Org-mode 语法

- 加粗用 `*bold*`（单星号），禁止 `**bold**`
- 标题层级从 `*` 开始，不跳级

#### ASCII Art

所有图表、拓扑、卡片，一律使用纯 ASCII 字符绘制。

允许字符集：`+ - | / \ > 
           |    |    |    |    |
  产出     .    .    .    .    .   线性预期
           .    .    .   /
  实际     .    .    . _/         <-- 阈值
           .    .    ./
           .____.___.'............   无效区
           |
       "原来这段全是白费的"
           |
           v
  决策改变: 不追问"做了多少"
            要追问"过没过线"
```

碰撞有多种形状——分叉、张力、阈值、缺口、翻转。选跟碰撞本身匹配的空间结构，不要把所有碰撞都压成同一种图。

论文的推测性观点如果有趣，也做成碰撞卡片——标注"开放问题"，只有方向没有结论。写一个尖锐的问题，不是温和的 checkbox。值得追就追得下去，不值得追一眼就知道。

### 步骤 5：生成 Org 报告

1. 按 Denote 文件规范（见约束 L0）获取时间戳
2. 文件名：`{时间戳}--paper-{简短标题}__read.org`
3. 读取 `references/template.org` 获取报告结构，按模板填充
4. 写入 `~/Documents/notes/{文件名}`

## 输出质量标准

- **只有两个部分**：论文说了什么 + 对我意味着什么。不加别的
