 ## Tooling

   For example, use `nix shell nixpkgs#python3 -c python3 <script>` for one-off Python commands.
 - Stage new files that Nix discovers through flake evaluation before testing.
-  Flake evaluation ignores untracked files, so auto-loaded modules must be tracked before `nixos-rebuild --flake` can see them.

 - Never manually modify `CHANGELOG.md` files or files marked as auto-generated.
   Detect auto-generated files with a layered check.
   Trust an explicit in-file marker first, for example `AUTO-GENERATED, DO NOT EDIT`.
-  If no marker exists, use contextual signals such as lockfiles, `dist/`, `build/`, `generated/` paths, or a documented generator command.

 ## Corrections
