/**
 * ReverseGuard — Recipe→Code 反向验证
 *
 * 正向: 代码 → Guard → "代码是否符合知识？"  ✅ 已有
 * 反向: Recipe → Guard → "知识是否还符合代码？" ← 本文件
 *
 * 对每条 active rule Recipe:
 *   1. 提取 coreCode 中的 API 引用（类名、方法名）
 *   2. 在 code_entities 表中查找这些符号
 *   3. 符号不存在 → PatternDrift
 *   4. 提取 guard regex pattern → 对项目代码运行匹配
 *   5. 匹配率骤降 → 代码模式正在迁移
