 - CC/Direct 工具桥的执行前后成果指纹、回执结算 JoinError/落盘失败，以及外部 MCP journal 的读取/JSON 行解析原先仍会被 `.ok()`、固定回执句或“无记录”吞掉；现分别保留指纹阶段、回执任务/落盘原因、journal 行号和底层正文，只有真实 `NotFound` 才视为空记录。
 - 外部 MCP `resources/read` 仍把已能返回具体原因的 Codex journal 读取错误 `unwrap_or_default()` 成空资源；现把读取失败按 MCP 错误响应返回，Direct 执行会话当前项目 canonicalize 也保留底层 I/O 正文。
