- factor_definition 表（migration b7f2a5e81c33，MySQL 已应用）：name 主键 + 元数据 （formula/brief/frequency/lookback/direction/requires JSON/version）+ FactorDefinition entity（from_registry_def 由代码注册表构造） - FactorRepository Protocol + SQLAlchemy 实现（幂等 upsert/list/get） - /api/factors 改读 DB；目录为空自动 seed 注册表（幂等）—— 保留自定义因子登记能力 （计算仍须代码注册，引用未注册因子照常 FactorError，防伪因子） - tests/test_factor_catalog.py（repo 幂等/roundtrip/registry seed、API seed+字段齐全）； test_api 的 client fixture 补 tmp sqlite session（factors 读库）；全量 pytest 通过
