+| Status | implemented-awaiting-runtime-validation |
+| Owner | 当前任务 Agent |
+
+## 修改边界
+
+- 客户端 project_snapshot 与实际窗口生命周期、相关定向测试。
+- shared-contracts 快照清单及后台 DTO、platform-oss 的受控清单枚举、api-server 管理员列表与 ZIP 下载、后台权限映射。
+- api-server 快照存储配置解析：默认目标与素材 bucket 分离，只有凭据可回退；不变更部署配置或搬迁对象。
+- admin-web 项目列表、现有路由/导航/API client 与相应测试。
+- 主规范、运维说明及必要共享约定。不修改 SpacetimeDB、External API、用户会话权威或线上配置。
+
+## 实现顺序
+
+1. 评审主规范与本里程碑，复现客户端项目枚举故障。
+2. 并行实现后台列表/ZIP、后台 UI；客户端只修已证实上传缺陷并补清单元数据。
+3. 集成契约、运行定向测试和 UI smoke，核查真实清单可还原目录；按证据更新验收状态。
+
+## 验证命令
+
+- `cargo test --locked -p platform-oss`、`cargo test --locked -p api-server project_snapshot`、`cargo test --locked -p shared-contracts`（server-rs）。
+- `cargo test --locked --manifest-path apps/ai-game-creator-shell/src-tauri/Cargo.toml project_snapshot`。
+- `npm run admin-web:typecheck`、`npm run admin-web:build`、后台相关 Vitest。
+- `npm run check:encoding`、`npm run check:doc-index`、`git diff --check`。
+
+## 风险与回滚
+
+旧清单无完整性声明，只能标记未知；完整工程含项目源码、素材和配置，排除依赖/构建缓存、凭据、会话与运行日志。下载失败不修改 OSS 或清单。本轮按用户授权提交推送，不部署；代码可独立回退。

+| Parent Spec | `docs/technical/【技术方案】AI游戏创作智能体App实施计划-2026-06-24.md` 的项目快照上传与后台工程下载合同 |
+
+## 目标与范围
+
+修复实际项目自动上传的已证实故障，并让有权限的后台管理员按项目查看远端快照、一键下载按原始目录还原的工程 ZIP。
+
+## 不在范围内
+
+客户端上传 UI、跨设备恢复、版本历史、数据库 schema、线上部署、自动补传全部未打开项目。
+
+## 依赖与前置条件
+
+延续现有私有 OSS 项目快照、平台会话与后台权限。真实 bucket 已只读确认只有两份历史模板清单；上传根因必须经确定性复现后修正。
+
+## 验收标准
+
+- [ ] 正式项目窗口可被同步调度识别；周期与关闭触发保持有界，失败有项目级诊断。
+- [ ] 未单独配置快照目标时仍使用 agc-dev，只复用资源存储凭据；显式快照目标保持有效，不迁移现存对象。
+- [ ] 后台列表显示项目名/ID、用户 ID、同步时间、文件数、体积和完整性，支持刷新与分页。
+- [ ] ZIP 按清单还原相对路径；不含对象存储摘要目录；空文件可上传与导出。
+- [ ] 清单名称/完整性变化在无内容差异时也提交，partial 可恢复 ready，历史缺字段不冒充 ready。
+- [ ] 缺失、损坏、越界路径和非完整清单失败关闭；历史未声明完整性的清单明确标记，允许导出已有文件但不称为完整工程。
+- [ ] 无后台权限不能读取项目或 ZIP；不泄漏凭据；ZIP 构建有体积、并发和临时文件清理边界。
+- [ ] 定向 Rust 测试、后台类型检查/构建、UI smoke、编码、文档索引和 diff 检查完成，运行时证据与未验证部分分别列出。
+
+## 证据要求
+
+自动化覆盖窗口身份、上传零字节、清单统计、目录还原、路径与校验和校验、后台路由权限。运行时优先只读现有 OSS 清单；测试不上传真实用户工程、不修改线上数据。
+
+## 已取得证据
+
+| 层次 | 结果 |
+| --- | --- |
+| 客户端 Rust `project_snapshot` | 22 通过、1 忽略（写入式真实上传 smoke 未运行）；含排队退出等待回归 |
+| 客户端前端生命周期与启动器 | 3 文件、10 测试通过；完整 AGC typecheck、skill-pack、check-config 通过 |
+| 后台页面、API client、路由与样式 | 44 测试通过；admin-web typecheck/build 通过 |
+| 后端快照与权限 | 14 定向测试通过；未认证路由矩阵与页签映射 2 测试通过 |
+| 默认存储目标 | 真实 AppConfig::from_env 配置回归 1 通过 |
+| OSS 存储层 | 全量 55 测试通过，含签名、特殊字符路径、读取上限与零字节 |
+| 真实 OSS 只读导出 | `project_snapshots_live_readonly_list_and_archive` 通过；limit=1 分页、2 清单、12 文件、73,424 字节，ZIP 解压路径/长度/摘要全匹配、临时文件清理通过；两份均为历史 unverified |
+| 浏览器 smoke | 模拟 API 的 1280 桌面与 390 窄屏通过；下载按钮可见，无整页横向溢出；中文 ZIP 文件名、Authorization、409 错误呈现通过 |
+| 通用门禁 | 编码、文档索引、production-ops、Rust 格式、客户端 Prettier 与 diff 检查通过 |
+
+## 剩余验证与环境边界
+
+`npm run dev:api-server -- --api-port 4198 --bgfilter-worker-port 4199 --api-timeout-seconds 600` 编译成功，但当前工作区配置的本地数据库 `xushi-p4wfr` 在 `127.0.0.1:3101` 返回 404，启动认证投影无法完成，故 `/healthz` 及完整 HTTP smoke 未通过。仅本任务启动的 API/worker 已停止；没有清库、迁移数据库、改 `.env` 或替换其它项目的验证目标。
+
+尚未替换安装版、构建新客户端发布包或部署；提交推送按用户本轮授权执行。当前条款已有上述自动化与只读存储证据，最终验收仍等待当前工作区数据库就绪后的 HTTP 联调，以及新客户端的隔离实机自动上传验证；完成后再关闭里程碑并清理两份计划。

 # 踩坑与排障记录
 
+## AGC 自动同步必须绑定真实项目生命周期
+
+- 正式客户端在单窗口中用 React 状态打开/切换工程，窗口 URL 不代表当前工程。原生后台同步应读取由当前窗口显式登记的活动工程；首次打开、离开、切换、关窗及退出等待分别验证，不能只用携带 `projectPath` 的独立测试窗口证明正式入口可用。
+- 增量文件没有变化不等于远端清单没有变化。项目名和完整性元数据也参与提交判据，避免临时跳过恢复后永久停留在 partial，或新出现超限文件后仍显示 ready。历史清单缺少完整性字段属于未知，不能默认成完整。
+- ZIP 导出按一次冻结清单恢复相对路径并逐文件核验；直接下载内容寻址的 OSS 目录不能得到可用工程。源码/素材归档不包含依赖缓存、凭据和 AGC 对话运行状态。
+
 ## 2026-09-19 资源 kind 词汇收敛后，前端判据与 fixture 必须一起按 canonical 成员重写
 
 - **现象**：工具栏入口的 `assetKind` 换成共享 `GameCreationAppAssetKind`（图集从平台词 `art-spritesheet` 改成 `icon-spritesheet`）后，「图集不接受用户参考」的判据仍写在旧的 `['art-spritesheet']` 字符串清单里，判据恒假：生成面板重新给图集渲染参考图选择器，原生提交再按合同显式拒绝多余参考。
