/**

|
* TDD-gate real-test verification — router-gate v4 spec §3.11.
|
|
* Pure ядро + тонкая fs-обёртка. Закрывает sentinel-gaming (touch test без expect/it).
|
|
*
|
|
* DEVIATION: spec §3.11 показывает @babel/parser AST. Babel не установлен —
|
|
* regex-based extraction per спек note "basic regex + import check; AST refinement future".
