-当前 Windows 自动更新已启用差分下载。
+当前 Windows 自动更新统一使用全量安装包下载。
 
 依赖产物为：
 
 - `CipherTalk-x.y.z-Setup.exe`
 - `latest.yml`
-- 至少一个 `*.blockmap`
 
-工作流会在构建、GitHub Release 发布、R2 镜像同步阶段强校验 `*.blockmap` 是否存在；缺失时直接失败，避免退回全量更新而未被发现。
+工作流会在构建与发布阶段校验安装包和 `latest.yml` 的哈希是否一致，避免元数据与真实安装包不匹配。
 
 说明：
 
 - 当前仍是未签名发布
-- 未签名状态下差分更新可以工作
 - 公开分发时稳定性仍可能受 SmartScreen / 杀软 / 系统策略影响
-- 若差分下载失败，`electron-updater` 应回退到完整包更新，不修改现有 UI 交互
+- 当前已禁用差分更新，客户端始终下载完整安装包
