Agent Notes (dotfiles)

Never use Git worktrees

Never create, enter, or use a Git worktree for this repository. Work only in the primary checkout at /srv/dotfiles.
Do not use Codex/Claude task modes or helpers that create a worktree for this repository.
Do not place worktrees for nested repositories anywhere under /srv/dotfiles.
Run NixOS activation only as just switch from /srv/dotfiles/nixos (or the /etc/nixos symlink to it). Never activate from another checkout and never point DOTFILES_WORKTREE at a temporary path.
This repository uses Home Manager out-of-store links. Activating from a disposable checkout makes live dotfiles point into that checkout and breaks them when it is removed.
