+- 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`.
