Executive Summary + +Устранена проблема хранения OAuth-состояний и пользовательских сессий исключительно в памяти одного процесса Node.js (`MemoryOAuthTransactionStore` и `MemorySessionStore`), из-за которой в multi-instance / serverless среде или при перезапуске сервера происходили сбои аутентификации VK ID и сброс активных сессий пользователей. + +Реализованы персистентные хранилища на базе PostgreSQL / Prisma: +1. В `prisma/schema.prisma` добавлены модели `OAuthTransaction` (с полями `state`, `codeVerifier`, `redirectTarget`, `createdAt`, `expiresAt`) и `Session` (с полями `sessionId`, `userId`, `user`, `createdAt`, `expiresAt`), а также индексы по `expiresAt` и `userId`. +2. Создана SQL-миграция `prisma/migrations/20260821120000_persistent_auth_stores/migration.sql`. +3. В `src/lib/auth/oauth-state.ts` реализован `PrismaOAuthTransactionStore` с атомарной транзакционной операцией `consumeTransaction` (`$transaction` find + delete), предотвращающей race conditions и гарантирующей single-use семантику OAuth state. +4. В `src/lib/auth/session.ts` реализован `PrismaSessionStore` со строгой валидацией TTL и каскадным удалением сессий при удалении пользователя. +5. Настроены фабрики `createOAuthTransactionStore()` и `createSessionStore()`: при `STORAGE_DRIVER=memory` или `NODE_ENV=test` используются in-memory реализации, в остальных случаях — Prisma-драйверы. +6.
