    • CI tests across multiple environments or versions.
  • Linting and formatting60
    • Linter or formatter configured (.editorconfig).
  • Reproducibility25
    • No Cargo.lock found (−70 pts). Rust binary/application crates should commit Cargo.lock.Run `cargo build` and commit the resulting Cargo.lock file.
    • No Dockerfile or runtime version pin found. Adding one earns +10 pts.Add a Dockerfile, .nvmrc, or .python-version to pin the runtime version and make the environment reproducible.
