 - 第二轮 Agent/CC 旁路扫描继续发现执行许可/执行会话/MCP 本地读取/编辑器 worker/Cocos worker 的 JoinError，以及 MCP future panic，会被固定成“任务未返回/异常/需要核对”；现把 join/panic 正文并入既有 ToolFailure / MCP 错误载荷，保留 `needs-reconciliation` 的不可自动重放语义。Native 定向测试：Direct MCP 33 项、Direct Tool Bridge 41 项、CC 14 项均通过。
 - 最新漏扫又补出 Direct Tools MCP 启动/运行退出码、Skill `resources/read` 索引与资源读取、交付 `finish_sealing` 错误三处固定句；现在分别写入 stderr、MCP 错误正文和交付复核底层原因，避免只剩退出码或“暂不可用/复核失败”。
 - 前端继续实测发现预览活体复用的 IPC / 权限拒绝会被当成“没有活体”并静默重启，资源生成事件订阅失败也只回退轮询；现在两条回退仍保留，但分别把复用失败正文附到重启结果、把订阅失败正文附到任务阶段。预览与生成队列定向测试 25 项通过。
+- 继续扫前端外围又发现 Direct 回合后的清单刷新、资源卡片预览未知错误、UI 编辑器单图预览读取失败仍会静默或使用无因固定句；现分别进入运行错误出口、保留脱敏后的预览错误正文并在编辑器状态提示中显示。
+- 资源依赖图读取失败原先只切到 fallback 布局状态，用户看不到 IPC/权限正文；现把安全错误保存到状态并在依赖画布内联显示。
