 Закрыта критическая уязвимость манипуляции результатами розыгрышей (**Seed Grinding / Pre-computation attack**), при которой организатор мог локально перебрать seed'ы на открытом списке участников и передать в `POST /api/giveaways/[id]/draw` подобранный seed, гарантирующий победу нужного участника при успешном статусе верификации `verified: true`.
 
 Реализована схема **Cryptographic Seed Pre-Commitment**:

-## 4. Verification Evidence & Test Gate
+## 4. API Contract & Database Migration
 
-Фактически выполненные команды:
+- **Database Migration Required:** `NO` (Поле `Giveaway.seed` уже существует в `prisma/schema.prisma` как nullable `String?` и готово к сохранению CSPRNG seed).
-
+- **API Contract Changes:**
-1. `npx prisma generate` → Exit code 0 (Prisma Client v5.22.0 generated).
+  - `POST /api/giveaways`: поле `seed` удалено из входящего тела (автоматически отбрасывается `.strip()`).
-2. `npm test` → Exit code 0 (48 test files, 280 tests passed, 0 failed).
+  - `POST /api/giveaways/[id]/draw`: поле `seed` строго запрещено в теле запроса (`.strict()`), возвращает `400 VALIDATION_ERROR` при попытке передачи.
-3. `npm run lint` → Exit code 0 (Next.js ESLint passed clean).
+  - `POST /api/giveaways/[id]/snapshot`: в ответ добавлено поле `seedCommitment: string` (SHA-256 hex от сгенерированного seed).
-4. `npm run build` → Exit code 0 (Production build & static generation compiled successfully).
+  - `GET /api/giveaways/[id]`: в объекте `giveaway` возвращается `seedCommitment: string | null`. До статуса `DRAWN` поле `giveaway.seed` маскируется (`null`), после проведения розыгрыша раскрывается исходный `seed`.
-
+  - `GET /api/giveaways`: поле `seed` отсутствует в `GiveawaySummary` и не утекает в списках.
-### Regression Tests Summary (`tests/seed-precommit-gate.test.ts`):
-- `adversarial attempt to pass custom seed in draw body fails with 400 and keeps status SNAPSHOT_LOCKED` → PASS
-- `grinding regression: local brute-force of 100 seeds cannot alter the pre-committed API winner` → PASS
-- `draw attempt on giveaway without locked snapshot and seed returns 409 Conflict` → PASS
-- `GET /api/giveaways/[id] masks seed before DRAWN and exposes seedCommitment` → PASS
-- `after DRAWN, sha256(seedUsed) strictly equals seedCommitment and verify endpoint succeeds` → PASS
-- `MemoryGiveawayRepository generates and locks seed during createAndLockSnapshot` → PASS
-- `PrismaGiveawayRepository maps seedCommitment correctly` → PASS

+## 6. UNVERIFIED Assertions & Tech Debt
+
+1. **UNVERIFIED: Prisma integration harness with live DB:**
+   - В текущем тестовом сьюте все функциональные тесты выполняются с драйвером `STORAGE_DRIVER=memory`. Хотя `PrismaGiveawayRepository` полностью реализован, компилируется (`tsc --noEmit`), собирается (`npm run build`) и покрыт маппинг-тестами, его сквозное выполнение в интеграционном тесте с реальной БД PostgreSQL не автоматизировано в Vitest.
+   - **Рекомендация / Proposed Next Task:** Добавить тестовый сьют `tests/prisma-integration.test.ts` для запуска прогона репозитория против тестового экземпляра PostgreSQL.
+
+2. **CRITICAL Finding Status:**
+   - Исполнитель не объявляет CRITICAL finding автоматически закрытым самостоятельно. Требуется независимое re-review ревизии.
