Summary

After running compact, the session lost the active git worktree context and switched back to the main repository directory.

The expected behavior is that the session should continue operating inside the previously active worktree. Instead, after compacting the context, the execution environment appears to have fallen back to the main repository path and branch, which creates a risk of applying changes to the wrong branch.

Current State After Compact

After compacting, the actual execution context is:

pwd
/Users/clouds3n/Coding/open-source/ai/Tron

git branch --show-current
master

git status
clean

The registered git worktrees are:

/Users/clouds3n/Coding/open-source/ai/Tron
  -> master

/Users/clouds3n/.codex/worktrees/Tron/feature/clouds3n/openapi-open-app-management/base
  -> feature/clouds3n/openapi-open-app-management/base

What steps can reproduce the bug?

1. Create a new chat with new git worktree, and start long-time working inside the worktree
2. Let it automatic trigger compact
3. After compacted, observe or ask the assistant to verify the current execution context

What is the expected behavior?

After compact, the session should preserve:

• the active working directory
• the active git worktree
• the active branch
• the intended execution context for future file edits and shell commands
