This spec covers the reflection-based routing pattern declared in `deputy-webapp/app/api/v1/routers/ResourceRouter.php`, enumerated over every ORM class registered in `DeputecApplication::$arrSystems` in `app/prepend.inc.php`.\n\nResources support create/update/delete only if they also appear in `$arrSystemsAPIEditable` — read-only resources expose GET / QUERY / INFO / PREDICT / HISTORY only."
