The guides load a bundled design specification through pilotr_example() rather than by a path relative to the repository. The old path resolved only inside a checkout, so a reader who had installed pilotr and copied the line met a missing-file error.
The R package gains a package-level help topic, ?pilotr, and model_formula() now binds the global environment so a formula prints without the build-varying environment tag that leaked into the rendered reference pages.
Both twins move together, so the Python distribution is republished at the shared version.
