- 移除 bd/mg 两平台及磁盘残留产物；清理 api-test 死脚本、musicSdk/message+options 死模块、infSign vendor - musicSdk/ 改名 sdk/；src/common、src/auth、src/apis 整体移入 sdk/，依赖方向定为 src → sdk 严格单向 - src/ 手写 JS 全量转 .ts，删除 JS 类型垫片 modules.d.ts；源码 import 统一 .ts 后缀 - Node 原生类型剥离直接运行 .ts（engines >=22.18），取消 tsc 发射产物，tsc 仅类型检查（pnpm typecheck） - 删除 kwdes 备用实现与 src/index.ts 转发垫片；测试移至 test/smoke-test.ts - common/request.ts 补显式导出类型；修复 set-cookie 单值形态、ApiError 类字段等隐患 验证：tsc 零错误，smoke-test 41/41
