+# Backend Architecture Refactor
+
+Дата: 2026-06-25
+Статус: draft
+
+## Контекст
+
+После аудита backend-архитектуры от 2026-06-25 и последующей фичи
+`backend-architecture-improvements` большая часть первого слоя долга закрыта: общий envelope DTO,
+domain exceptions, dependency-aware health checks, DI-подключение middleware и разделение
+`MoexClientService`.
+
+Оставшийся долг неоднороден. Часть пунктов требует новых продуктовых или доменных решений
+(`T-Bank` multi-tenancy, локальный read-path истории операций, device sessions, ledger-модель). Эти
+изменения не должны попадать в локальный рефакторинг без отдельной спецификации, потому что меняют
+поведение, модель данных или threat model.
+
+Текущая фича фиксирует только refactor-only итерацию: привести существующий backend к более
+правильным архитектурным границам без добавления новых пользовательских возможностей и без изменения
+публичной формы API, кроме уточнения валидации некорректных входных данных.
+
+## Цель
+
+Снизить backend technical debt в существующем поведении за счёт точечных архитектурных правок:
+безопаснее обрабатывать ошибки, формализовать production-конфигурацию, усилить DTO-валидацию,
+сузить `any` на границе T-Bank gRPC, улучшить cache metadata и синхронизировать опубликованную
+backend-документацию с текущим кодом.
+
+## Требования
+
+### 1. Error masking для необработанных исключений
+
+Backend не должен возвращать клиенту внутренние сообщения необработанных `Error` в ответах `500`.
+Подробности должны оставаться в backend-логах. Публичный ответ для unknown/internal errors должен быть
+стабильным и безопасным.
+
+### 2. Production configuration hardening
+
+Backend должен явно отделять dev defaults от production-конфигурации:
+
+- production-запуск не должен молча использовать дефолтные JWT access/refresh secrets;
+- CORS с credentials не должен отражать произвольный origin в production;
+- список допустимых origins должен задаваться конфигурацией окружения.
+
+### 3. DTO validation hardening
+
+Существующие DTO должны отсеивать заведомо некорректные значения до попадания в service-layer:
+
+- даты покупки позиции должны валидироваться как ISO/date строки;
+- количество позиции не должно допускать `0` там, где service-layer уже трактует это как ошибку;
+- изменения должны сохранять существующий успешный пользовательский сценарий для валидных данных.
+
+### 4. T-Bank gRPC typed boundary
+
+Динамическая природа protobuf/gRPC клиента должна быть локализована в одном typed boundary, чтобы
+доменные broker-сервисы не приводили service clients к `any` напрямую. Цель — улучшить compile-time
+границы без переписывания vendored proto contract и без изменения внешнего T-Bank API behavior.
+
+### 5. Cache metadata consistency
+
+Cache helper должен сохранять полезность `meta.cachedAt`: cache hit не должен выглядеть как состояние
+без времени кеширования, если timestamp уже можно сохранить вместе с cached payload.
+
+### 6. Backend documentation sync
+
+Опубликованные docs в `apps/docs/docs/backend/` должны отражать текущее состояние backend после
+закрытых refactor-работ:
+
+- split MOEX clients вместо устаревшего `MoexClientService` как единого God Service;
+- актуальный envelope contract;
+- актуальные health response и broker operations sync endpoint.
+
+## Ограничения
+
+- Не добавлять новые user-facing возможности.
+- Не менять публичный API shape для успешных ответов.
+- Не вводить multi-tenancy или пользовательские T-Bank connections в рамках этой фичи.
+- Не переводить операции T-Bank на локальный read-path в рамках этой фичи.
+- Не менять модель сессий на device/session table в рамках этой фичи.
+- Не менять финансовую модель хранения (`Float`, `Int`, JSON/string fields) и не создавать ledger ADR в
+  рамках этой фичи.
+- Не выполнять механическое дробление больших сервисов без проверяемой архитектурной цели.
+- Не редактировать Prisma migrations вручную.
+
+## Acceptance Criteria
+
+- Необработанные backend exceptions логируются, но `500` response не раскрывает внутренний
+  `Error.message`.
+- Production-конфигурация не стартует с дефолтными JWT secrets и не использует wildcard/reflected CORS
+  для credentialed requests.
+- DTO портфельных позиций валидируют даты и количество на boundary-уровне; добавлены regression tests.
+- Production-код broker-сервисов не содержит прямых `as any` для получения T-Bank gRPC service clients;
+  небезопасное приведение, если оно необходимо, локализовано и покрыто типом/facade.
+- Cache metadata на hit/miss согласована тестами и не ломает `ApiEnvelopePayload`/`ApiResponse` contract.
+- Backend docs обновлены и не ссылаются на удалённый `MoexClientService` как primary abstraction,
+  устаревший `/operations/refresh` endpoint или raw health response без envelope.
+- Затронутые backend tests проходят.
+- Backend build проходит.
+- OpenAPI/types обновляются только если реально меняется Swagger contract; `apps/frontend/src/api/types.ts`
+  не редактируется вручную.
+
+## Out Of Scope
+
+- T-Bank data isolation and multi-tenancy.
+- Local T-Bank operations read-path.
+- Device-level sessions, refresh-token rotation и reuse detection.
+- Ledger/financial data model migration.
+- Rate limiting, CSRF и security headers, если они требуют отдельной threat model или middleware policy.
+- Декомпозиция `PortfolioService` или `tbank/` на новые модули без отдельного плана.

+- [x] Task 1: Mask unhandled `500` errors without changing `HttpException` responses.
+- [x] Task 2: Harden production runtime config for JWT secrets and credentialed CORS.
+- [x] Task 3: Harden portfolio position DTO validation for quantity and buyDate.
+- [x] Task 4: Localize T-Bank gRPC `any` casts behind typed facade methods.

+- [x] Task 6: Synchronize published backend docs with current MOEX/envelope/health/T-Bank contracts.
+- [x] Task 7: Run final lint/test/build/docs quality gate and inspect final diff.
+
+## Verification Log
+
+- Baseline backend tests: 30 files, 141 tests — PASS.
+- Baseline backend build: PASS.
+- Final backend lint: PASS.
+- Final backend tests: 34 files, 158 tests — PASS.
+- Final backend build: PASS.
+- Final docs build: PASS.
+- No `getServiceClient('X') as any` in production broker services: 0 matches.
+- No `MoexClientService` or `operations/refresh` in docs: 0 matches.
