P1 通用查询：viewsets / app / menu / mail / gitea / mc / stats / sync_apps 等视图与命令的裸查询改委托 SDK Manager（Role/Company/Department/Position/Menu/Tenant/App）。 P2 App 体系：app_manager.py 与 app_manifests.py 实现零裸 ORM，职务多值/虚拟职务/公司下拉全部走 SDK。 P3 工具下沉：money/json_encoder/celery_utils/exception_handler/redis_lock 改为纯转发展开；ip_filter/storage 转发并注入 app.ini 配置源；common 下 DateTime/String/Naming/UUID 转发 SDK。 删除死代码 commission/strategies/engine.py（SDK 已有同物且零引用）与 payment/models.py 的 FromTenantAndPlatform；单测 patch 目标同步为 gvsdsdk.*，test_attack_detect fixture 补齐限频去重状态。
