## CR-07验收口径
|
||||
|
||||
- iFinD、图表、实时观察器和Provider适配器必须只在`build_data_gateway`创建，并由容器共享。
|
||||
- Tushare必须继续通过实时Token供应器按需创建，不能为了减少对象数量缓存过期Token。
|
||||
- 市场服务中为原版隔离测试桩保留的一处`TushareClient(self.token)`是明确兼容例外，不得被误判为
|
||||
第二条正式数据链路。
|
||||
- 不得合并Tushare、iFinD、东方财富和腾讯的传输、缓存、重试或降级逻辑。
|
||||
|
||||
## CR-07结果
|
||||
|
||||
- 全后端构造点扫描确认iFinD、MarketChart、东方财富图表和实时观察器均只有网关一个创建位置；
|
||||
`ApplicationContainer`暴露的是同一对象引用，没有第二份客户端。
|
||||
- Tushare Provider使用动态Token供应器，市场服务只有一处已登记测试兼容回退；本批没有发现可安全
|
||||
删除的生产实现，因此不为追求行数强行修改运行代码。
|
||||
- 架构清单新增Provider创建所有权，自动测试会在未来出现第二个未登记构造点时失败。
|
||||
- 候选322项、纯`app/`导出259项、24个JavaScript文件、API/架构注册表、Git空白检查和SQLite
|
||||
完整性检查通过；本批不涉及页面、CSS或浏览器行为。
|
||||
- 本批不修改请求频率、缓存、重试、Token更新、数据源选择、计算口径、API、数据库或前端。
