# Task 09: Паритет eligibleParticipantsCount между драйверами Report

## 1. Executive Summary
|
||||
|
||||
Устранено расхождение в вычислении `eligibleParticipantsCount` между `PrismaGiveawayRepository` и `MemoryGiveawayRepository`:
|
||||
|
||||
1. **Единая семантика `eligibleParticipantsCount`:**
|
||||
- **После жеребьёвки:** возвращается зафиксированное значение `drawResult.totalEligibleCount`.
|
||||
- **До жеребьёвки:** возвращается актуальное количество участников, прошедших фильтры (`eligible === true`).
|
||||
|
||||
2. **Эффективный Prisma-запрос (без загрузки массивов):**
|
||||
- В `PrismaGiveawayRepository.listGiveawaysSummary` добавлен пакетный агрегат через `prisma.participant.groupBy` по ID неразыгранных конкурсов (`WHERE giveawayId IN (...) AND eligible = true`).
|
||||
- Сохранена легковесность маршрута `GET /api/giveaways`: массивы участников (`participants`, `eligibleParticipants`) и приватные сиды (`seed`) по-прежнему исключены из передачи по сети.
|
||||
|
||||
3. **Анализ паритета всех полей `GiveawaySummary`:**
|
||||
- Проверены все 20 полей контракта `GiveawaySummary`:
|
||||
* `id`, `platform`, `sourceUrl`, `platformOwnerId`, `platformPostId`, `title`, `postImageUrl`, `postLikesCount`, `postCommentsCount`, `postRepostsCount`, `status`, `winnersCount`, `reserveWinnersCount`, `organizerId`, `createdAt`, `updatedAt`, `drawnAt`, `totalParticipantsCount`, `eligibleParticipantsCount`, `hasDrawResult`, `algorithmVersion`.
|
||||
- Подтверждена 100% эквивалентность значений и типов между Memory и Prisma реализациями.

|

| File | Type | Description |
|
||||
|------|------|-------------|
|
||||
| `src/lib/repository/prisma-repository.ts` | Storage Driver | Реализован эффективный подсчет `eligibleParticipantsCount` через `groupBy` для неразыгранных розыгрышей. |
|
||||
| `tests/summary-count-parity.test.ts` | Tests (NEW) | Набор тестов (4 теста) на корректность и легковесность `listGiveawaysSummary` (до жеребьёвки, после, при 0 подходящих, проверка легковесности API). |
|
||||
| `tests/integration/prisma-repository.test.ts` | Tests | Добавлен интеграционный тест 12 на паритет подсчетов в PostgreSQL. |

# Task 09: Паритет eligibleParticipantsCount между драйверами
|
||||
|
||||
**Assigned to:** Antigravity (Implementation Orchestrator)
|
||||
**Priority:** MEDIUM (UI data accuracy & driver parity)
|
||||
**Date:** 2026-08-21
|
||||
**Base SHA:** `4e095553a11636cca298e75c799c92b07eb31396`
|
||||
|
||||
## Scope
|
||||
1. Harmonize `eligibleParticipantsCount` calculation across `PrismaGiveawayRepository` and `MemoryGiveawayRepository`:
|
||||
- Single unified semantic:
|
||||
* If `drawResult` exists (after draw): use `drawResult.totalEligibleCount`.
|
||||
* If before draw: calculate `eligibleParticipantsCount` as the count of eligible participants (`eligible === true`).
|
||||
2. Efficient Prisma query:
|
||||
- In `PrismaGiveawayRepository.listGiveawaysSummary`, do NOT load full participant records.
|
||||
- Use Prisma relational count with filter or aggregate:
|
||||
In Prisma query:
|
||||
```prisma
|
||||
_count: {
|
||||
select: {
|
||||
participants: true,
|
||||
}
|
||||
}
|
||||
```
|
||||
To count eligible participants without full records:
|
||||
In Prisma schema, `participants` is a relation on `Giveaway`.
|
||||
Can Prisma do `_count` with filter in `select`?
|
||||
In Prisma Client 5.x:
|
||||
```typescript
|
||||
_count: {
|
||||
select: {
|
||||
participants: true,
|
||||
}
|
||||
}
|
||||
```
|
||||
Prisma 5 does not support filtered `_count` inside `select` on nested relations, but we can do a grouped/filtered count or query efficiently.
|
||||
Let's check how Prisma handles `_count` or how `listGiveawaysSummary` is implemented.
|
||||
3. Check all other fields of `GiveawaySummary` for driver parity:
|
||||
- `id`, `platform`, `sourceUrl`, `platformOwnerId`, `platformPostId`, `title`, `postImageUrl`, `status`, `winnersCount`, `reserveWinnersCount`, `createdAt`, `updatedAt`, `drawnAt`, `totalParticipantsCount`, `eligibleParticipantsCount`, `hasDrawResult`, `algorithmVersion`.
|
||||
4. Keep `GET /api/giveaways` lightweight (zero participant arrays, zero seed leakage).
|
||||
5. Create test suite `tests/summary-count-parity.test.ts`.
|
||||
6. Full gate verification & report in `agents/antigravity/done/TASK-2026-08-21-09-summary-count-parity.md`.
