[Bug]: Set to use worktrees, but the AI appears to still be working from my original code path

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

Not sure

Steps to reproduce

I create a new chat, it's set to use worktrees by default.
I work through some issues and the AI claims to have a fix - often it's NOT actually in the worktree but in the original code path of my original checkout.

Expected behavior

Makes it really hard to know where the changes are being made and how to test. I have to double check every time changes are made that they are in the right place.

Actual behavior

When I create a new chat and it's set to use worktrees. I should be safe in knowing all modifications are being made in that worktree, and not in the main code repository path (outside of ~/.t3)

Impact

Major degradation or frequent failure

Version or commit

No response

Workaround

I tell the AI to re-apply the changes in the worktree, which it then does.
