 ## Environment Configuration
 
 All config is in `.env` at project root. Key settings:
-- `FLASK_HOST` / `FLASK_PORT` (default 127.0.0.1:8023)
+- `FLASK_HOST` / `FLASK_PORT` (default 127.0.0.1:8021)
 - `FLASK_SECRET_KEY` — must be >= 16 chars or app refuses to start
 - `DB_*` — 数据库连接，**多库支持**（`config/database.py` 的 `_build_database_url()` 按 `DB_DRIVER` 构建 URL）：`mysql`(默认)/`postgresql`/`mssql`/`sqlite`/`oracle`（oracledb 驱动，thin 模式无需 Oracle Client；`DB_DATABASE` 填 SERVICE_NAME）。切换只需改 `DB_DRIVER` + 账号，然后运行 `python scripts/setup_db.py`（`create_all` 建表 + 种子数据，幂等）。注意：`flask db migrate/upgrade`（方案 B）仍针对 MySQL，新建其它库请用 `scripts/setup_db.py`
 - **跨库数据迁移**：`python scripts/migrate_db.py --src-driver=mysql --src-host=127.0.0.1 --src-port=3306 --src-db=<源库名> --src-user=root --src-pass=<密码> --dst-driver=postgresql --dst-host=127.0.0.1 --dst-port=5432 --dst-db=<目标库名> --dst-user=postgres --dst-pass=<密码> --drop-target-first`。CLI 显式参数、不依赖 `.env`；源/目标均支持 `mysql/postgresql/mssql/sqlite/oracle`（别名 `postgres=postgresql`、`sqlserver=mssql`、`sqlite3=sqlite`），自动建目标库 + `create_all` 建表 + 逐表泵数据 + 按方言重置自增（PG setval / MSSQL CHECKIDENT / Oracle 补 sequence+触发器）+ 逐表行数校验；先加 `--dry-run` 干跑核对计划
