message: |
  A file that imports `std::process::Command` via `use` must also `use command_error::CommandExt` (import it as
  `use command_error::CommandExt as _;`) so command execution goes through the checked methods
  (`status_checked` / `output_checked` / `spawn_checked`), whose errors carry the command line and exit status --
  a raw `std` `Command`'s `.status()` / `.output()` / `.spawn()` errors carry none of that. If a call genuinely
  needs the raw outcome (e.g. a test that asserts a non-zero exit, or an exit-code proxy), fully-qualify
  `std::process::Command` at the call site instead of importing it, so this rule does not apply.
