Question: Why is the current session file path no longer shown in the Trace panel?

## Question

The Trace / Inspector panel (追踪) previously showed the current session file location. I can no longer find that location in the panel.

Was this entry intentionally removed or moved elsewhere? What was the reasoning behind the change?

When something goes wrong in a conversation, my workflow is to copy the session file path and give it to an AI assistant so it can read the session data and help diagnose the problem. Without an accessible path, I cannot easily do that from the UI.

Where should users now find and copy the current session's file location, or what is the intended replacement workflow for having an AI assistant inspect a problematic session?

This issue is only a question about the change and the intended troubleshooting workflow, not a bug report about cost estimates or a request for a specific implementation.

中文说明

之前「追踪」面板里添加过当前会话文件位置，现在找不到了。想请问这个入口是有意移除了，还是移到了其他地方？当时是怎么考虑的？

我的使用场景是：当某个会话出现问题时，直接复制当前会话文件的地址，交给 AI 读取会话数据、帮助排查。现在看不到这个位置，就没办法方便地从界面复制地址让 AI 看问题。

现在应该在哪里找到并复制当前会话文件位置？如果不再提供这个入口，预期用什么方式让 AI 检查有问题的会话？

这个 Issue 仅提问，想了解改动原因和目前推荐的排查方式，不涉及费用估算问题，也不要求某种具体实现。

The issue names only the Trace / Inspector panel and its missing session-file-location entry; no source file or test is identified. Start by locating that panel and reviewing the relevant UI history, then document whether the path was removed or moved and state the supported workflow for copying or inspecting a session.
