Verification and troubleshooting

Use the smallest check that proves the package source and hook converged.

High-signal checks

brew bundle check --global
mise ls --current
cargo install --list
uv tool list
yarn global list
gh extension list

For one tool:

command -v <tool>
<tool> --version

If a package disappeared

Check	Why
Is it declared in the right source list/template?	declarative cleanup removes undeclared packages
Did the corresponding hook run?	run_onchange hashes decide whether a hook re-runs
Is it scoped to the current .isWork profile?	template branches can hide personal/work-only tools
For Homebrew, is it in the assembled Brewfile?	cleanup uses ~/.Brewfile, not the partial you edited in isolation
For Go, did this tooling install it?	the state ledger prevents deleting hand-installed binaries

Rollback pattern

For managers with cleanup support:

1. Remove the declaration from the source list.
2. Run chezmoi apply.
3. Run the manager-specific verification command.

For managers without cleanup support, removal from the list only stops future installs. Check Reconcile behavior and follow the recipe-specific manual uninstall step, such as gem uninstall <gemname> for Ruby gems.

For custom DMG apps and single-file binaries, manually remove residual app/binary files only when the installer cannot safely do it.
