### Custom Rubric Override

To use `{{rubric}}`, provide a JSON array of criteria:

```json
[
  {"name": "拼写", "weight": 0.25, "desc": "单词拼写与大小写"},
  {"name": "语法", "weight": 0.30, "desc": "时态与句法"},
  {"name": "内容", "weight": 0.25, "desc": "是否完成所有要求"},
  {"name": "书写", "weight": 0.20, "desc": "标点与格式"}
]
```

When provided, the custom rubric replaces the default 5-item rubric entirely; weights must sum to 1.0.

## Grade-Level Error Priority

| Grade | Primary Focus | Secondary Focus |
|-------|--------------|-----------------|
| 3 | 字母大小写、基础拼写、标点 | 词序 |
| 4 | 动词be/have/do形式、名词复数 | 介词搭配 |
| 5 | 一般现在/过去时态、主谓一致 | 连词使用 |
| 6 | 从句（宾语/定语）、段落衔接 | 词汇丰富度 |
