 ## Critical: git worktrees for every branch and PR
 
 Never create a branch, commit, or open a pull request in the primary checkout. Always use a linked git worktree so the main working tree stays on `main` and stays clean. Do not `git switch` / `git checkout` a feature branch in the primary directory, and do not leave it dirty.
