//! Unit tests for the bare-`tm`-outside-a-git-work-tree menu (#6666).
//!
//! Why: the whole point of `guided_outside_git` is that the routing decision,
//! the input parse, the advertised commands, and the orchestrator are all
//! reachable without a daemon, a terminal, or a spawned process. These tests
//! exercise each of those seams directly.
//! What: routing table, choice parsing, argv construction, the options block's
//! agreement with that argv, and the orchestrator's static / interactive /
//! quit / listing-failure paths.
//! Test: this file.
