 - Контракт HTTP — `api/openapi.yaml`. Читай нужную операцию и связанные схемы. Generated-код (`**/gen/**`, `**/generated/**`) и lock-файлы исследуй точечно; не редактируй вручную.
 - После изменения OpenAPI: `pnpm --filter @pipu/api-client generate`, затем из `services/api`: `go generate ./...`. Проверяй и коммить результат генерации.
 - Новые правила размещай у владельца сценария, IO — в адаптере. Сохраняй явные границы транзакций и платформенные особенности. Узкий интерфейс вводи для конкретного потребителя.
-- Промежуточно запускай проверки затронутой области; перед сдачей — необходимые связанные проверки. Команды запускаются из корня, если не сказано иначе.
-- Общие проверки: `pnpm typecheck`, `pnpm test`, `pnpm i18n:check`, `pnpm test:scripts`. Go: из `services/api` — `go vet ./...`, `go test ./...`. Python: из `services/recommender` — `uv run ruff check .`, `uv run mypy pipu_rec`, `uv run pytest`.
+- Локально достаточно запускать проверки затронутой области и непосредственно связанных сценариев. Полный набор тестов и проверок повторно выполняется в CI/CD; не запускай все проверки проекта перед каждой сдачей без необходимости. Расширяй локальную проверку при изменении общих контрактов, межмодульных зависимостей или при обнаружении ошибок. Команды запускаются из корня, если не сказано иначе.
+- Справочник полных проверок (выбирай локально только относящиеся к изменению): `pnpm typecheck`, `pnpm test`, `pnpm i18n:check`, `pnpm test:scripts`. Go: из `services/api` — `go vet ./...`, `go test ./...`. Python: из `services/recommender` — `uv run ruff check .`, `uv run mypy pipu_rec`, `uv run pytest`.
 - Не меняй пользовательские артефакты, локальные бинарники и посторонние незакоммиченные файлы.
