 - **Overlays** (`overlays/`) inject dependency package sets into nixpkgs (`rpkgs`, `baseRPackages`, `basePythonPackages`, plugins). Top-level `rWrapper` and `quarto` are compatibility conveniences, but `pkgs.rpkgs` is the canonical R surface for downstream configuration.
 - **cat-packages.nix** is the single source of truth for per-category packages. Each list is gated by its cat toggle.
 - **deps.nix** wires `catPkgs` into the wrapper's runtime PATH.
-- **settings.lang_packages** holds project-specific language libraries appended to the built-in `settings.langPackageDefaults`, used by local outputs and downstream module consumers.
+- **settings.lang_packages** holds the shared defaults used by local outputs and downstream module consumers.
 - **flake.nix** exports `lib.eval`, `lib.mkWrapper`, `lib.devShellPackages`, and `lib.shellHook` as the canonical downstream helpers, and builds `packages.default` and `devShells.default` from the same module config.
