// Сценарии решений владельца (ожидаемо КРАСНЫЕ до этапа 4 Codex).
// Публичного API для ролей точки/бухгалтера/директора, пакетов зарплаты и согласия
// на биометрию пока нет, поэтому тесты написаны против наиболее вероятного контракта,
// описанного в tests/e2e/NOTES-FOR-EXECUTORS.md (C1–C3). Если Codex выберет другой
// контракт — меняется только этот файл и NOTES, смысл проверок остаётся.
