+  /**
+   * 把识别接口返回的**单据标准字段**合并进 `state.documents`。
+   *
+   * 为什么必须合并：邮件详情的 `attachments[].documents[]` 只是一个**摘要**
+   * （`task_id` / `document_type` / `status` / `operator_decision`），
+   * 基金代码、申请日期、申购金额、机构这些字段**只在识别接口的返回里**
+   * （`_mail_detail` vs `_recognition_payload`）。只用摘要渲染，
+   * "单据核对与运营动作"里的单据信息就全是 `--`。
+   *
+   * 合并口径（**逐条按 task_id 匹配**，不是整段替换）：
+   *   - 两侧都有 → 识别侧字段优先，摘要里独有的键（status/operator_decision）保留；
+   *   - 只有摘要侧 → 原样保留（不能因为识别接口没提到就丢掉单据）；
+   *   - 只有识别侧 → 也要出现（例如刚生成、邮件摘要还没刷新）。
