- uv 工程（Python 3.12，pyproject + uv.lock，dev: pytest/ruff） - 分层包结构：api / application / domain / infrastructure / quant(qlib_adapter) / agent / core - app.core.config：加载根 config.yaml + .env，sqlite 相对路径解析到项目根 data/ - SQLAlchemy Base + Session 工厂（Infrastructure 层，业务走 Repository） - Alembic 迁移环境就位（env.py 复用应用配置，render_as_batch 兼容 SQLite） - GET /api/health + pytest 冒烟 6 项通过 / ruff clean / uvicorn 启动验证
