VS Code extension shows the same global 51 conversations in every workspace

I am experiencing the same issue（#3550） in the current VS Code Codex extension.

Every VS Code project shows the same 51 conversations. This is not caused by
opening a parent directory or the wrong workspace: I open each repository in
its own pinned VS Code window.

I inspected the local Codex state database:

• 93 total threads
• 20 distinct cwd values
• only 4 threads belong to the currently opened repository
• nevertheless, the extension displays the same 51 conversations in every repository

This confirms that workspace detection and per-thread cwd metadata are
correct, but the VS Code conversation list is not filtering by the active
workspace. The usability problem becomes progressively worse as global
conversation history accumulates.

In-product feedback IDs:

• 019f6010-c0fc-7031-97b6-d2f6e7c40fd4
• 019f6e18-144a-7672-9309-a6612fa03193

VS Code Codex extension version: 26.609.30741
Platform: Windows + WSL

Related issues:

• #3550 described the same workspace-scoping problem, but it is closed and the

problem is still reproducible in the current extension.

• #15368 documents a 50-thread recent-conversation page limit, which may explain

why the extension displays 51 conversations.
