/**

 * Every companyable list endpoint is exercised as a NON-SUPERUSER caller
 * scoped to company A, with a matching row present in company B. If any
 * row belonging to company B appears in the response, the test fails and
 * we know a scoping regression is loose in HTTP land, even if the
 * model-level scope tests are still green (e.g. a controller called
 * withoutGlobalScopes, joined bypassed a scope, or used a raw query).
 *
 * Users are covered by tests/Feature/Users/Api/IndexUsersTest;
 * tests/Unit/CompanyScopingTest covers the model-level equivalents. This
 * suite is the outer defense — controller-level and route-level.
