//! CLI canary smoke test. Pinned to one canonical encode round-trip; runs
//! the `md` binary via `assert_cmd::Command::cargo_bin("md")`. Run with
//! `cargo test -p md-cli --test smoke` (or `cargo test -p md-cli`) to ensure
//! the test target is built against md-cli's `[[bin]]`; a workspace-wide
//! `cargo test --workspace` works today because md-cli is the only crate
//! defining `[[bin]] name = "md"`, but pinning `-p md-cli` is robust against
//! future workspace additions.

    // due to 6-bit primary tags + 4-bit version + `is_nums` flag + kiw
    // formula change to ⌈log₂(n)⌉.
    // `--group-size 0` keeps this wire canary an exact unbroken-stdout pin; the
    // default md encode output is now space/5-grouped (mstring-grouping P1).
