  # Guards against issue #40: the sdist embeds the Rust workspace root to resolve the
  # `core` path dependency, but ships only the crates in the dependency graph. If the
  # workspace manifest ever references a member it doesn't ship (e.g. `wasm`), `cargo`
  # can't load it and downstream packaging (OpenSUSE/OBS `cargo vendor`) breaks. This
  # builds the real sdist and confirms its embedded workspace manifest actually loads.
