'use strict';

/**
 * Regression tests for #3406 — stale globally-installed `@gsd-build/sdk@0.1.0`
 * shadows the `gsd-sdk` shim that `get-shit-done-cc` installs. The standalone
 * 0.1.0 binary only knows `run | auto | init` (no `query` subcommand), so
 * every workflow that calls `gsd-sdk query <command>` fails until the user
 * runs `npm uninstall -g @gsd-build/sdk`.
 *
 * Maintainer decision (per triage): option 2 — detect-and-warn during
 * install. This test pins the pure detection helper so the install-time
 * warning fires on the right input and stays silent otherwise.
 *
 * Test surface is the exported helper `detectStaleStandaloneSdk(runNpmLs)`.
 * `runNpmLs` is an injected executor: in production it spawns
 * `npm ls -g @gsd-build/sdk --json --depth=0`; in tests we hand it a stub
 * that returns canned stdout / throws, so the test never touches the host
 * npm state.
