The file tree is scoped to one lane at a time. Switching lanes changes the worktree you are editing. Check the lane selector before saving if you have several lanes open.
When a merge or rebase produces conflicts, Files shows the conflicted files and lets you resolve them in the editor. After resolving, continue the Git operation from the lane or PR workflow.
Use Files as the final human checkpoint. Even when an agent says tests passed, inspect the diff yourself before pushing.
