已完成本轮迁移：管理后台、审批流和考务编排的业务 API 已全部由 ASP.NET Core 10 原生处理。

主要完成：
管理端招生工作台、指标资格、招生学校账号。
招生计划审核、分数优先多志愿投档、退档监督。
逐轮录取公示、报到审批、补录轮次推进、最低录取线公示。
成绩预览导入与管理员账号禁止物理删除。
新增迁移开关及健康状态：[MIGRATION.md (line 57)](C:\\Users\\BI\\Documents\\EIS-dotnet\\MIGRATION.md:57)
核心实现：[AdminAdmissionService.cs (line 10)](C:\\Users\\BI\\Documents\\EIS-dotnet\\src\\Eis.Infrastructure\\Administration\\AdminAdmissionService.cs:10)
原生路由：[NativeAdminReadEndpoints.cs (line 209)](C:\\Users\\BI\\Documents\\EIS-dotnet\\src\\Eis.Web\\Administration\\NativeAdminReadEndpoints.cs:209)
