"""Transport for the `check` domain — args in, delegate, format out. **Zero logic lives here.** Every command should read as: parse, call a service, turn the result into output. If a command grows a branch that is about the *problem* rather than about *presentation*, that branch belongs in `service.py`. Note what the commands below no longer do: no `console.verdict(..., ok=False)` followed by `raise typer.Exit(1)` at each failing branch. They raise `ReachError` with a remedy and `@command` does the rest — renders the verdict once, last, and exits non-zero. That is the difference between a contract and a habit, and it is why every command here wears `@command`. The service import is deliberately at module level: by the time this module is imported at all, `reach` has decided to run a `check` command, so there is nothing left to defer. Laziness lives one level up, in `main.py`.
