 - MySQL 是**已有数据库**，应用只通过向导写入的 `DB_URL`、`DB_USERNAME`、`DB_PASSWORD` 连接它；安装器不安装 MySQL、不创建数据库、不修改数据库服务。填写 `127.0.0.1` 表示 MySQL 与 Java 应用在同一台服务器，端口以实际监听端口为准，不默认假设 `3307`。
 - 安装阶段只校验 JDBC 配置格式，不调用 `mysql`/`mariadb` 客户端，也不执行 `CREATE`、`INSERT`、`UPDATE`、`DELETE` 或 `DROP`。首次向导点击“完成安装”后，应用才会在**专用空 schema**中运行 Flyway 建表并初始化管理员；这是业务初始化，不是安装 MySQL 服务。在线更新默认跳过数据库备份；需要备份时由运维显式设置 `KAIDI_DB_BACKUP_MODE=mysqldump`，更新器只调用已有工具，不会安装数据库。
 - `KAIDI_APP_PORT` 只决定 Java 回环监听端口，默认 `18080`；反向代理必须指向安装器输出的 `PROXY_TARGET`。安装器不会替你修改 Nginx 或宝塔站点配置。

+本版本修复在线更新完成后后台看不到 Release 更新日志的问题。
+
+• 更新日志继续以签名 release-manifest.json 为唯一发布来源，Gitea Release 正文与清单使用同一份内容。
+• 发布制品新增 release-metadata.json，并由签名制品携带版本、发布时间和完整更新说明。
+• 应用重启后会从当前已验签制品恢复更新说明；即使由旧版更新器完成版本切换，也不会再丢失日志。
+• 更新完成后的终态审计会保存 Release 更新说明，系统更新页按版本显示完整日志，而不是只显示“更新成功”。
+• 增加发布清单与制品内元数据的一致性校验，避免版本、发布时间和更新说明发生漂移。
+
+升级说明：本版本不要求安装 MySQL，也不会自动修改数据库服务；更新器默认跳过数据库备份，仅使用已验签的 Release 制品完成应用切换。
