本阶段迁移已完成。

Excel：班级、账号、考生、缴费、考场、成绩、志愿、录取、报到及正式录取名册均改为 ClosedXML 原生处理，支持模板、校验、筛选和导入预检。[SystemWorkbook.cs](C:\\Users\\BI\\Documents\\EIS-dotnet\\src\\Eis.Infrastructure\\Spreadsheets\\SystemWorkbook.cs)
文书：录取通知书模板、成绩单/准考证/通知书业务数据与防伪验真已脱离 Node；保留现有前端排版导出效果。[AdminAdmissionService.Documents.cs](C:\\Users\\BI\\Documents\\EIS-dotnet\\src\\Eis.Infrastructure\\Administration\\AdminAdmissionService.Documents.cs)
缓存：完成 Redis 命名空间版本缓存、有界本地回退、请求合并和并发失效保护；公开数据及成绩写入后立即失效。[ApplicationCache.cs](C:\\Users\\BI\\Documents\\EIS-dotnet\\src\\Eis.Infrastructure\\Caching\\ApplicationCache.cs)
迁移清单已更新为完成。[MIGRATION.md](C:\\Users\\BI\\Documents\\EIS-dotnet\\MIGRATION.md)
