+测试可显式启用持久解析/向量缓存；解析按真实源内容、影响锚点的名称和解析/切分指纹寻址，向量按嵌入文本序列、模型资产及执行指纹寻址。缓存不包含 workspace/document ID、绝对临时路径、数据库或 job 状态，绑定和索引写入始终在当前隔离存储完成。依赖指纹变化、快照结构/向量形状或完整性不匹配时重新计算，原子发布避免半成品。测试调度、预热与强制冷跑规则见 [测试规范](../test.md#调度与缓存)。

 ### 共享用户 Skill 资产
 
 `userData/skills/{name}/` 保存用户导入或手动创建的标准 Skill 文件夹，包含 `SKILL.md` 与可选的 `scripts/`、`references/`、`assets/` 及其他普通文件。导入复制整个所选目录，不引用源路径，也不扫描平台账号或用户主目录。原始 YAML（包括未知字段）和资源字节保持不变。共享资产不是伙伴运行缓存，删除伙伴或清理 runtime 不删除它。
