- RequestInput::queryArray() — no callers
- LocaleResolver::getAvailableLocales() / getDefaultLocale() — unused getters
- EmailVerificationService::getExpiryMinutes() — constant wrapper, never called
- AuthService::loginAndRedirect() — convenience wrapper, never called
- DepartmentService::listForUserAssignments() — no callers
- UserTenantContextService::getAvailableDepartmentsByTenant() — no callers

Dead functions (3):
- navActivePublicPages(), appNormalizeStringList(), appNormalizePositiveIntList()

Dead constant (1):

Orphaned file (1):
- bin/cli-bootstrap.php — never included anywhere
