+//! Script-provided command E2E compatibility check: a `composer.json` script naming a
+//! `Symfony\Component\Console\Command\Command` subclass is imported as an application command,
+//! and `list`, `help`, executions and the mismatched-name warning are compared between upstream
+//! Composer and Shirabe.
+//!
+//! The whole fixture is Shirabe-authored (`fixtures/e2e-script-command/`), so nothing has to be
+//! fetched; the test skips only while the PHP runtime or the Composer checkout is missing.
