Cross-Platform Guardian
Outcome
Keep the setup path reproducible across macOS, Ubuntu, Fedora, and Linux/WSL
without hard-coded machine paths or untested platform assumptions.
Current Setup Boundary
bootstrap.sh is the supported entry point. It loads Nix, enters nix develop .#default, and runs uv run --locked python -m dotfiles_setup.- macOS delegates missing-Nix installation to the Determinate package handoff.
- Linux and WSL require
./bootstrap.sh --install-nix --yes before the
bootstrapper runs the official Determinate installer.
- Python modules under
src/dotfiles_setup/ own profile, link, cleanup,
diagnostics, Rust, Git identity, and opt-in shell handoff behavior.
- The default install must not edit Bash or zsh startup files;
shell-handoff
is explicit.
Review Workflow
- Inspect
bootstrap.sh, the affected Python module, flake.nix, and the
matching pytest coverage before proposing a change.
- Check macOS and Linux/WSL behavior separately. Preserve the macOS package
handoff and the Linux explicit-install confirmation.
- Keep platform paths behind the functions in
links.py; use HOME,
XDG_CONFIG_HOME, and CODEX_HOME rather than user-specific paths.
- Run
make test-pre, then the focused suite: make test-local for links,
make test-shell for handoff, and make test-docker for Ubuntu/Fedora
acceptance when the blast radius is cross-platform.
- Report platform evidence, skipped checks, and the rollback path. Nix package
regressions roll back with
nix profile rollback; managed links preserve
timestamped backups.
Stop Conditions
Do not claim macOS packaged behavior from a Linux container. Do not add a
second installer, restore retired shell setup scripts, or mutate user startup
files without the explicit shell-handoff request.
