+`.gitea/workflows/project-ci.yml` 的 `Native shell tests` 在运行原生壳门禁前，必须使用 `cargo fetch --locked` 预取 `server-rs/Cargo.toml`、桌面壳和 AGC 壳三份依赖。AGC 壳检查还会运行 `platform-llm` 与 `shared-contracts` 的 server-rs workspace 测试，这些命令以及 AGC 壳测试必须带 `--locked`，避免在测试阶段重新解析 registry index；锁文件发生变化时应先更新受信任 CI 镜像缓存，再重跑门禁。

 - 严格图集崩溃补充：规范图和背景图的两文件 rollback 不覆盖严格图集事务已经整体修改的 `.agent/manifest.json`、私有回执、公开清单、主图集、四切片和切片清单。必须在严格调用前持久化 pending 及九项旧合同身份；重启恢复先对账底层严格事务，完整新合同直接收口完成，完整旧合同才补偿前两阶段，混合或漂移状态失败关闭。不要在严格提交成功后局部恢复前两张图。
 - 部分旧包补充：rollback 的规范图/背景图必须保存旧字节与旧 manifest entry，不能把这两项缺失隐式当成空内容；显式 `regenerate` 因此只在这两项可信可回滚时开放。历史主图集、私有回执、公开清单或 canonical 切片可以缺失，但八个严格路径与受管顶层 asset identity 必须逐项冻结其真实 `Present/Some` 或 `Missing/None` 状态，补偿也必须恢复相同存在性。不要因为旧美术包缺切片而阻断重生成，也不要把本轮新建的严格文件误记成旧文件。
 - 对话扫描与 claim 补充：历史中出现 `User A / User B / Assistant B` 时，B 已回答不代表 A 已回答，扫描必须继续寻找 A。成功 Direct 回复在 Rust 返回前已经落盘，前端冗余 append 失败不能据此重跑；普通错误回复的显式落盘失败时，恢复 claim 要保持到 React fallback writer 的同一 messageId append 明确收敛。writer 成功或明确失败后才释放；失败路径要停止该消息的自动迟到重试，再由显式 `/history` 复用原 stable turn。终态后及时删除 claim，避免 Set 无界增长。

+## Native shell CI 不能在测试阶段重新解析 Cargo registry（2026-08-26）
+
+- 现象：原生壳 job 的依赖预取成功后，AGC 检查仍在 `platform-llm` 测试阶段重新更新 registry index，并因 `symphonia` 下载的 TLS EOF 失败。
+- 原因：native job 没有显式预取 `server-rs/Cargo.toml`；`ai-game-creator-shell:check` 的 server-rs workspace 命令没有 `--locked`。
+- 处理：native job 预取 server-rs、桌面壳和 AGC 壳三份 lockfile；`platform-llm`、`shared-contracts` 与 AGC 壳测试统一使用 `--locked`，不降低原生测试门禁。
+- 验证：workflow 回归测试、锁定的 Rust 测试和原生壳门禁均需运行；若本地 EAS CLI 版本漂移，应单独报告环境阻塞，不把它误判为本次 Cargo CI 修复失败。
