/**
 * Evidence 的来源语义与来源标签。
 *
 * 不能退让的约束：
 * 1. **消息类型**与**派生来源**是两个正交维度，UI 必须分别标出来：
 *    前者说"原始消息是什么"（文本 / 图片 / 语音…），
 *    后者说"这条结果是靠什么命中的"（OCR命中 / 转写命中）；
 * 2. authoritative source 仍是原始消息 —— messageRef 不变，跳转目标就是它；
 * 3. 派生命中内容必须自报来源（`OCR摘录：` / `转写摘录：`），
 *    不能被读成群友真的发过这样一段文字；
 * 4. 引擎内部前缀（`图片文字：` / `OCR:` / `system-ocr`）绝不出现在用户可见文本里；
 * 5. 普通文字消息只标「文本消息」，不凭空多出来源标记。
