DELETE /api/factors/custom/{id} 的 404 守卫把 store.delete_one 当成存在性
探测, 但它会真的 unlink 文件并返回 True。当定义在盘上却没进注册表时
(load_into_registry 对注册失败的定义只告警跳过, 如复合因子的成员已被强制
删除), get_factor 为 None, 短路求值会走到 delete_one, 定义随即被删除。
随后的引用检查再返回 409「该因子仍有引用, 拒绝删除」—— 接口声称拒绝, 定义
却已经没了; 用户改带 force=true 重试只会得到 404, 定义无法恢复。
把 fail-closed 的引用检查移到存在性判定之前, 保证任何拒绝路径都不改磁盘。
