//! The closed vocabulary of command outcomes.
//!
//! `Outcome` has exactly one variant per command, named after the command and
//! ordered to mirror `cli.rs`'s subcommand tree, so the two can be diffed at a
//! glance. Per-command message structs live in their own command modules; this
//! enum only aggregates and delegates. A command with multiple terminal shapes
//! (e.g. `deploy approve`) owns a command-local enum in its own module, and
//! the top-level variant here wraps it.
//!
//! `reason` strings are an external, stable contract: kebab-case, named
//! deliberately, never renamed after release.
