//! The parts of the CLI that are worth running from somewhere other than the
//! command line.
//!
//! [`invariants`] holds the conversion properties: what must survive a format
//! conversion, stated once. `powerio-cli/tests/conversion_matrix_report.rs`
//! holds the vendored cases to them and [`corpus`] holds an arbitrary corpus
//! to the same ones, so the gate in CI and the harness pointed at private data
//! cannot drift apart.
//!
//! The `powerio` binary is the CLI proper; everything else about it lives in
//! `src/main.rs`.
