//! Exit codes.

//! These are the CLI's contract with CI systems and pre-commit hooks, so a
//! caller can gate on a scan without parsing the report.
//!
//! An execution error outranks findings: if the scan could not complete, the
//! caller must not read a `1` and conclude the code merely has issues.
