- app.ts 单体路由拆分为 routes/ + helpers + middleware + static 独立模块 - 类型去重：CheckFailure/CheckResult 以 shared/api.ts 为唯一源头，收紧 phase 联合类型 - es-toolkit 替换：isPlainObject/isNil/isEmptyObject/isEqual/isError/Semaphore/groupBy - Bun 内置 API：Object.fromEntries 替代手写 headersToRecord - bun:sqlite 规范：prepare() → query() 利用内置缓存，避免 N+1 查询 - 新增 getLatestChecksMap/allGetTargetStats 批量查询方法 - 新增 backend-code-quality/api-route-separation/batch-data-queries 规范 - 补充 openspec/config.yaml 后端开发规范与 DEVELOPMENT.md 后端开发指引
