- alembic init + env.py 接 settings/models metadata（asyncpg->psycopg2 同步 URL） - 补 3 个 CheckConstraint 到 models（原只在裸 DDL） - 离线生成初始迁移（31 表+约束+95 索引，全 sa.* 通用类型） - init_db 用 _run_alembic_migrations（自动基线+upgrade head）替换 create_tables+ensure_schema_updates（删 92 行裸 DDL） - 删破坏性 migrate_db.py（drop_all） - 既有 DB 首次启动自动 stamp 基线，无需手动 Co-Authored-By: Claude <noreply@anthropic.com>
