 - Secret 值只从 YAML `sourceRef` 读取并写入目标 Secret。
 - CLI 输出只显示 `sourceRef`、`targetKey`、presence 和 fingerprint，始终保持 `valuesPrinted=false`。
+- `plan` 的数据库投影只显示 schema 和 DSN 参数 presence，不显示完整 DSN、用户名、密码或参数值。
 - 含 Secret 的 runner 文件使用 owner-only 权限，运行后立即删除；manifest 只在 runner 的临时目录存活，终态前由 trap 清理。
 - 状态和事件只记录公开 ID、阶段、typed code 和时间，不保存命令 stderr、DSN、manifest 正文或 Secret 值。
 - Secret 缺失会在连接测试集群前阻塞 `start`。
-- API 和 Worker 从同一 Secret 挂载严格的 PikaOA runtime YAML。
+- 迁移 Job、API 和 Worker 从同一 Secret key 挂载严格的 PikaOA runtime YAML，数据库 schema 与 `search_path` 因此保持一致。
 - OTel endpoint、Prometheus scrape、指标路径和探针全部由 target YAML 声明。
 - 配置一致性、镜像/commit 漂移和 OTel exporter 失败只产生 `blocking=false` warning，不作为 MVP 门禁。
