+
+## 入口与数据边界
+
+[`cloud_sync.rs`](../openless-all/app/crates/openless-core/src/cloud_sync.rs) 从共享 Core 仓储生成快照，使用现有 `MarketplaceConfig` 的官方地址和同一个 Marketplace 登录实例。GitHub OAuth token 只从 `CredentialStore` 读取，不经过 React，不包含在状态、事件或错误中；注销标记同样对云同步生效。带凭据的请求不跟随重定向，正式地址要求 HTTPS，本机 HTTP 仅用于回环测试。

+| 同步内容 | 保持在本机的内容 |
+| --- | --- |
+| 词典、纠正规则、风格包文本与 PNG 图标 | API 密钥、OAuth token、渠道配置 |

+
+具体允许字段由 [`cloud_sync_types.rs`](../openless-all/app/crates/openless-core/src/cloud_sync_types.rs) 定义；不自动映射整个 `UserPreferences`。图标只读取 Core 拥有的资源目录，云端传输的是最多 64 KiB 的 PNG base64，恢复时重新分配本机文件路径。旧风格包的 JPEG/WebP 图标不进入这一版 PNG 同步字段。
+
+## IPC 与冲突处理
+
+Tauri 命令位于 [`commands/cloud_sync.rs`](../openless-all/app/src-tauri/src/commands/cloud_sync.rs)，仅委托 Core：
+
+| 命令 | 参数 | 结果 |
+| --- | --- | --- |
+| `cloud_sync_status` | 无 | `CloudSyncStatus`：schemaVersion、revision、updatedAt、hasSnapshot、三类数据数量 |
+| `cloud_sync_upload` | baseRevision、uiPreferences（locale / fontScale） | 更新后的状态 |
+| `cloud_sync_restore` | 无；界面须先确认覆盖本机可同步数据 | status 与 uiPreferences |
+| `cloud_sync_delete` | baseRevision；界面须先确认删除云端备份 | 空备份的新状态；本机数据不删除 |
+
+界面只接收数量和版本，不接收完整私有快照。上传与删除使用上次读取的版本，服务端原子比较版本；HTTP 409 转成 `BackendErrorCode::Busy`，`details.reason=revision_conflict`，同时给出 `currentRevision`。客户端不自动改版本重试。上传或删除发生网络错误且无法确认结果时返回 `OutcomeUnknown`，应先刷新状态再决定下一步。
+
+HTTP 请求和存储内容限 2 MiB；输入有条数、文本、PNG 结构及尺寸限制。服务端返回的所有内容均按同一严格 DTO 与限额校验。`translationTargetLanguage` 的空字符串保留“沿用默认输出语言”语义。
+
+## 本地恢复
+
+下载并完整验证后，Core 依次取得设置写入锁、词典锁、纠错锁、风格包锁和偏好锁，生成所有替换文件。凭据和设备字段从当前本机偏好保留；缺少的内置风格包由已有仓储规则补齐。
+
+[`cloud_sync_transaction.rs`](../openless-all/app/crates/openless-core/src/cloud_sync_transaction.rs) 先在目标文件所在目录准备新文件与原文件备份，再依次原子替换。某个写入失败时，以备份反向回滚已经替换的文件；全部文件完成后才更新仓储内存与 PreferencesChanged、VocabularyChanged、StylePacksChanged 事件。若回滚本身失败，保留 `.cloud-sync-*.backup` 并返回 `OutcomeUnknown` 和 `recoveryRequired=true`，不报告成功。
+
+正常完成或成功回滚后删除临时文件。该机制处理进程中可返回的文件错误；它不是 SQLite 式的跨文件崩溃恢复日志。
+
+## 验证
+
+[`cloud_sync_contract.rs`](../openless-all/app/crates/openless-core/tests/cloud_sync_contract.rs) 使用临时 App 数据目录、内存凭据与本机假服务，覆盖同步往返、账号凭据不出界、设备设置保留、版本冲突、删除、错误服务与无效内容，以及恢复准备失败。事务单元测试覆盖中途替换失败后的回滚和回滚失败的真实状态反馈。
+
+在应用目录运行：
+
+```bash
+cargo test -p openless-core --locked --test cloud_sync_contract
+cargo test -p openless-core --locked --lib cloud_sync_transaction
+```
+
+真实服务上线、GitHub 登录和安装包内的设备交互需要另按平台验收；本机假服务测试不代表生产服务已部署。
