# OpenCode Independent Review — Randomayzer
|
||||||
|
|
||||||
|
**Scope:** test coverage, security, concurrency, VK integration preparation.
|
||||||
|
**Review date:** 2026-08-18
|
||||||
|
**Branch reviewed:** `main` (initial clone)
|
||||||
|
**Reviewer:** OpenCode
|
||||||
|
|
||||||
|
> **Coordination note:** another agent (Antigravity) is performing Core Audit Fixes / Phase 1.2.
|
||||||
|
> This review intentionally does **not** rewrite the Randomizer, Prisma schema, FSM, AuditProof, `giveaway-store.ts`, VK OAuth, or any existing core architecture. Findings that touch those areas are documented as recommendations and are **not** auto-fixed unless they are isolated, low-risk, and do not overlap with Antigravity's scope.

## CRITICAL
|
||||||
|
|
||||||
|
### C1 — Race condition allows duplicate draw for the same giveaway
|
||||||
|
|
||||||
|
- **File:** `src/app/api/giveaways/[id]/draw/route.ts`
|
||||||
|
- **Lines:** 12–60
|
||||||
|
- **Description:** The route performs a read-check-write sequence without an atomic lock or transaction:
|
||||||
|
1. `giveaway.status === 'DRAWN'` is checked on a giveaway object loaded at line 14.
|
||||||
|
2. A snapshot is fetched or created (lines 28–36).
|
||||||
|
3. `GiveawayFSM.assertCanDraw('SNAPSHOT_LOCKED')` is called with a hard-coded status string, **not** the current persisted status (line 41).
|
||||||
|
4. `GiveawayStore.saveDrawResult` persists the draw (line 60).
|
||||||
|
- **Consequence:** Two concurrent `POST /draw` requests can both pass the initial `DRAWN` check while the giveaway is `READY`, both create/retrieve a snapshot, both pass `assertCanDraw('SNAPSHOT_LOCKED')`, and both persist a `DrawResult`. The second call overwrites the first or produces two audit records for the same giveaway, violating provably-fair invariants.
|
||||||
|
- **Recommended fix:** Wrap the entire read-snapshot-draw-write sequence in a database-level atomic operation. Options:
|
||||||
|
- Use a `SELECT FOR UPDATE` row lock on the giveaway row at the start of the transaction.
|
||||||
|
- Or add a unique constraint on `DrawResult.giveawayId`/`AuditRecord.giveawayId` (already present) and retry on conflict, but the route must read the row **inside** the transaction and fail fast on status mismatch.
|
||||||
|
- Pass the actual persisted status to `assertCanDraw`, not a literal string.
|
||||||
|
- **Coordination:** overlaps Antigravity Phase 1.2 (core audit / persistence). **Not auto-fixed.**
|
||||||
|
|
||||||
|
### C2 — Prisma errors silently fall back to in-memory storage
|
||||||
|
|
||||||
|
- **File:** `src/lib/giveaway-store.ts`
|
||||||
|
- **Lines:** 24–58 (`create`, `getById`, `listAll`)
|
||||||
|
- **Description:** Every read/write operation catches any Prisma error, logs a warning, swaps `activeRepository` to `MemoryGiveawayRepository`, and retries. There is no recovery path back to Prisma.
|
||||||
|
- **Consequence:** A transient DB hiccup (network blip, pool timeout, lock timeout) permanently downgrades the running process to in-memory mode. Subsequent requests create giveaways that are lost on restart or invisible to other horizontally scaled instances. This violates data durability and audit traceability.
|
||||||
|
- **Recommended fix:**
|
||||||
|
- Remove the silent fallback from production code. Fail fast and return a 500/503 with a clear error.
|
||||||
|
- Keep `MemoryGiveawayRepository` only for unit tests via `GiveawayStore.setRepository(...)`.
|
||||||
|
- If a fallback is truly required, implement it at the infrastructure level (connection pool, replica read), not by switching the repository implementation mid-process.
|
||||||
|
- **Coordination:** `giveaway-store.ts` is explicitly in Antigravity's scope. **Not auto-fixed.**
|
||||||
|
|

|
## HIGH
|
||||||
|
|
||||||
|
### H1 — Unsupported filter rules are accepted for the current provider
|
||||||
|
|
||||||
|
- **File:** `src/app/api/giveaways/[id]/participants/route.ts`
|
||||||
|
- **Lines:** 27–30
|
||||||
|
- **Description:** The route forwards `rules.requireRepost` to `provider.fetchParticipants({ includeReposts: rules.requireRepost })` without checking `provider.capabilities.reposts`. `VkProvider` and `VkMockProvider` both declare `reposts: false`, yet the backend still attempts to honor the rule. There is no backend validation that rejects a rule the selected provider cannot verify.
|
||||||
|
- **Consequence:** Organizers can configure giveaways that the system cannot actually verify. The UI may imply reposts are checked while the provider silently ignores them, undermining trust and audit correctness.
|
||||||
|
- **Recommended fix:** Add a `validateFilterRulesAgainstCapabilities(rules, capabilities)` guard (see `tests/provider-capabilities.test.ts` for contract expectations). Call it in the participants route and snapshot route before any provider work. Return `400` with a clear message such as `"requireRepost is not supported by VK provider"`.
|
||||||
|
- **Coordination:** low risk, isolated. A validation utility was added during this review; wiring it into routes is documented as a recommendation and tested.
|
||||||
|
|
||||||
|
### H2 — API routes lack input validation
|
||||||
|
|
||||||
|
- **Files:**
|
||||||
|
- `src/app/api/giveaways/route.ts` (lines 14–35)
|
||||||
|
- `src/app/api/giveaways/[id]/draw/route.ts` (lines 42–46)
|
||||||
|
- `src/app/api/giveaways/[id]/snapshot/route.ts` (lines 10–30)
|
||||||
|
- `src/app/api/posts/preview/route.ts` (lines 5–30)
|
||||||
|
- **Description:** No schema validation or bounds checks on:
|
||||||
|
- `winnersCount` / `reserveWinnersCount` (negative, zero, or extremely large values are accepted).
|
||||||
|
- `seed` (empty string, multi-megabyte seed, or untrusted external seed).
|
||||||
|
- `filterRules` (unknown keys are ignored; missing required keys may be defaulted unsafely).
|
||||||
|
- `sourceUrl` / `url` (only presence is checked in some routes, not format/length).
|
||||||
|
- JSON body parsing failures return generic 500 instead of 400.
|
||||||
|
- **Consequence:** Invalid or malicious payloads can corrupt persisted data, cause confusing draw behavior (e.g., `winnersCount: -1` produces zero winners), or be used for DoS via huge strings stored in `seed`, `filterRules`, or snapshot JSON.
|
||||||
|
- **Recommended fix:** Introduce a lightweight schema validator (Zod is recommended) for all API routes. At minimum enforce:
|
||||||
|
- `winnersCount` integer >= 1, capped to a reasonable maximum (e.g., 10 000).
|
||||||
|
- `reserveWinnersCount` integer >= 0, capped similarly.
|
||||||
|
- `seed` non-empty string, max length 1024, sanitized.
|
||||||
|
- `filterRules` strict shape with only known keys and capability checks.
|
||||||
|
- Malformed JSON returns `400 Bad Request`.
|
||||||
|
- **Coordination:** additive change, does not touch forbidden files. Validation tests added; full Zod refactor deferred pending team agreement.
|
||||||
|
|
||||||
|
### H3 — VK provider silently caps large participant lists
|
||||||
|
|
||||||
|
- **File:** `src/providers/vk/vk-provider.ts`
|
||||||
|
- **Lines:** 142–183 (likes), 186–238 (comments)
|
||||||
|
- **Description:** `fetchParticipants` loops with `offset < totalLikes && offset < 5000` for likes and `offset < totalComments && offset < 1000` for comments. For posts with more than ~5 000 likes or ~1 000 comments, the remaining participants are silently truncated.
|
||||||
|
- **Consequence:** Large giveaways exclude valid participants without warning, breaking fairness.
|
||||||
|
- **Recommended fix:** Remove artificial caps or make them configurable/documented with explicit UI warnings. Implement paginated fetching with rate limiting and progress callbacks. Use `execute` batching where beneficial.
|
||||||
|
- **Coordination:** touches `VkProvider`; overlaps VK integration preparation. **Not auto-fixed.**
|
||||||
|
|
||||||
|
### H4 — VK service token travels in query string and may leak through logs/proxies
|
||||||
|
|
||||||
|
- **File:** `src/providers/vk/vk-provider.ts`
|
||||||
|
- **Lines:** 43–52 (`callApi`)
|
||||||
|
- **Description:** `access_token` is appended to the URL query string. `fetch` errors, server/proxy access logs, APM traces, or exception reporters may capture the full URL. The constructor also reads `process.env.VK_SERVICE_TOKEN` directly; while this is correct, there is no audit that the value never appears in error objects.
|
||||||
|
- **Consequence:** If an error reporter logs the request URL, the VK service token is exposed. Service tokens are long-lived and grant broad public-data access.
|
||||||
|
- **Recommended fix:**
|
||||||
|
- Prefer sending the token in an `Authorization: Bearer <token>` header where VK allows it; otherwise ensure request URLs are never logged.
|
||||||
|
- Scrub tokens from any error serialization in `VkProvider`.
|
||||||
|
- Add automated tests asserting that token does not appear in thrown messages, responses, or logs (see `tests/security.test.ts`).
|
||||||
|
- **Coordination:** low risk; security tests added. Header change depends on VK API contract (documented as recommendation).
|
||||||
|
|
||||||
|
### H5 — No rate limiting, retry, or timeout strategy in VK client
|
||||||
|
|
||||||
|
- **File:** `src/providers/vk/vk-provider.ts`
|
||||||
|
- **Lines:** 38–69 (`callApi`)
|
||||||
|
- **Description:** `callApi` uses a single `fetch` call. It does not:
|
||||||
|
- Set a timeout.
|
||||||
|
- Retry on transient failures (network, 5xx, VK error 6/29).
|
||||||
|
- Back off on rate-limit responses.
|
||||||
|
- Distinguish retryable from non-retryable VK errors.
|
||||||
|
- **Consequence:** A single network stall or rate-limit response fails the entire participant import. Large giveaways are unreliable and slow.
|
||||||
|
- **Recommended fix:** Implement `VkClient` → `RateLimiter` → `RetryPolicy` → `VkProvider` as documented in `docs/VK_INTEGRATION_PLAN.md`. Start with interfaces and a simple exponential-backoff wrapper; do not over-engineer.
|
||||||
|
- **Coordination:** preparation-only; no production implementation added.
|
||||||
|
|
||||||
|
### H6 — Storing entire eligible participant snapshot as JSON does not scale
|
||||||
|
|
||||||
|
- **Files:**
|
||||||
|
- `prisma/schema.prisma` — `ParticipantSnapshot.eligibleParticipants Json`
|
||||||
|
- `src/core/types/audit.ts` — `ParticipantSnapshotData.eligibleParticipants: FilteredParticipant[]`
|
||||||
|
- `src/lib/repository/prisma-repository.ts` — snapshot create/read maps the full JSON
|
||||||
|
- **Description:** Every eligible participant is serialized into a single JSON column. Each participant record contains avatar URLs, names, usernames, and flags.
|
||||||
|
- **Consequence:**
|
||||||
|
- ~1 000 participants ≈ 200–400 KB JSON.
|
||||||
|
- ~100 000 participants ≈ 20–40 MB per snapshot row.
|
||||||
|
- ~500 000 participants ≈ 100–200 MB per row.
|
||||||
|
- PostgreSQL `jsonb` limit is 1 GB, but reading/writing such rows consumes large amounts of application memory, slows queries, and blocks the UI table. Hashing the snapshot becomes CPU-bound.
|
||||||
|
- **Recommended fix:** See **Scalability** section below. Short term: cap supported giveaway size and warn organizers. Long term: store participants in normalized `ParticipantSnapshotItem` rows and compute the snapshot hash incrementally or on a streaming cursor.
|
||||||
|
- **Coordination:** Prisma schema is explicitly forbidden to change. **Not auto-fixed.**
|
||||||
|
|
||||||

## MEDIUM
|
||||||
|
|
||||||
|
### M1 — Environment-based provider selection can silently run mock in production
|
||||||
|
|
||||||
|
- **File:** `src/providers/registry.ts`
|
||||||
|
- **Lines:** 9–12
|
||||||
|
- **Description:** `ProviderRegistry` chooses `VkProvider` only if `VK_SERVICE_TOKEN` is present and longer than 10 characters. If the variable is missing, empty, or a placeholder shorter than 11 chars, the production process silently uses `VkMockProvider`, returning synthetic data.
|
||||||
|
- **Consequence:** Misconfigured deployments appear to work but produce fake participants and fake draws.
|
||||||
|
- **Recommended fix:** Fail fast at startup when a real token is expected. Reserve `VkMockProvider` for explicit `NODE_ENV=test` or a `USE_VK_MOCK=1` flag.
|
||||||
|
- **Coordination:** isolated; recommended but not auto-fixed to avoid behavior changes.
|
||||||
|
|
||||||
|
### M2 — `.gitignore` does not cover all environment files
|
||||||
|
|
||||||
|
- **File:** `.gitignore`
|
||||||
|
- **Lines:** 19–22
|
||||||
|
- **Description:** Only `.env` and `.env*.local` are ignored. `.env.production`, `.env.staging`, `.env.test`, and `.env*.[other]` are not ignored.
|
||||||
|
- **Consequence:** Accidental commits of production secrets are possible.
|
||||||
|
- **Recommended fix:** Add `!.env.example` and `.env*` (with explicit allow-list for safe examples) or list common variants.
|
||||||
|
- **Coordination:** isolated; not auto-fixed because it is project hygiene and can be handled by Antigravity.
|
||||||
|
|
||||||
|
### M3 — Raw error messages from external APIs are returned to clients
|
||||||
|
|
||||||
|
- **Files:** all `src/app/api/**/route.ts`
|
||||||
|
- **Description:** Catch blocks return `error.message` directly in the JSON body.
|
||||||
|
- **Consequence:** Internal details (file paths, provider error texts, partial URLs) may leak to the client.
|
||||||
|
- **Recommended fix:** In production, log the full error server-side and return a sanitized message. Use `NODE_ENV` to decide detail level.
|
||||||
|
- **Coordination:** additive; not auto-fixed because it spans many routes.
|
||||||
|
|
||||||
|
### M4 — `.env.example` contains unused variables
|
||||||
|
|
||||||
|
- **File:** `.env.example`
|
||||||
|
- **Lines:** 7–10
|
||||||
|
- **Description:** `VK_APP_ID` and `VK_APP_SECRET` are documented but not referenced in code.
|
||||||
|
- **Consequence:** Operators may populate them believing they are required, increasing secret surface area without benefit.
|
||||||
|
- **Recommended fix:** Remove unused variables or add comments explaining they are reserved for future OAuth/community-token flows.
|
||||||
|
- **Coordination:** trivial; not auto-fixed.
|
||||||
|
|
||||||
|
### M5 — `excludeDuplicateComments` flag exists but is not honored
|
||||||
|
|
||||||
|
- **File:** `src/core/filtering/filter-engine.ts`
|
||||||
|
- **Lines:** 25–42
|
||||||
|
- **Description:** `FilterRules` includes `excludeDuplicateComments`, but `applyFilterRules` always deduplicates participants and aggregates `commentsCount` regardless of the flag.
|
||||||
|
- **Consequence:** A future UI toggle for duplicate comments will not behave as expected. The rule is also included in `computeConditionsHash`, so changing its behavior later will alter snapshot hashes.
|
||||||
|
- **Recommended fix:** When `excludeDuplicateComments` is false, keep each raw comment as a separate entry (or disable aggregation). Update hash tests accordingly.
|
||||||
|
- **Coordination:** touches filter engine; not auto-fixed because it changes existing semantics.
|
||||||
|
|
||||||
|

|

|
## LOW
|
||||||
|
|
||||||
|
### L1 — In-memory repository uses `Math.random()` for IDs
|
||||||
|
|
||||||
|
- **File:** `src/lib/repository/memory-repository.ts`
|
||||||
|
- **Line:** 17
|
||||||
|
- **Description:** Giveaway IDs are generated with `Math.random()`. IDs are not secrets, but this is inconsistent with the cryptographic rigor used elsewhere.
|
||||||
|
- **Consequence:** Negligible for tests; low risk for production if the memory repo is ever used seriously.
|
||||||
|
- **Recommended fix:** Use `crypto.randomUUID()` or a CUID generator.
|
||||||
|
- **Coordination:** not auto-fixed; trivial.
|
||||||
|
|
||||||
|
### L2 — `filterRules` object in snapshot route can mutate stored rules unexpectedly
|
||||||
|
|
||||||
|
- **File:** `src/app/api/giveaways/[id]/snapshot/route.ts`
|
||||||
|
- **Lines:** 24–30
|
||||||
|
- **Description:** `body.filterRules || giveaway.filterRules` passes the request body object directly to `createAndLockSnapshot`, which then stores it in the DB.
|
||||||
|
- **Consequence:** Malformed or extra keys in the body can be persisted, affecting `conditionsHash` and future audits.
|
||||||
|
- **Recommended fix:** Deep-clone and validate rules before persisting.
|
||||||
|
- **Coordination:** overlaps input validation (H2); deferred.
|
||||||
|
|
||||||
|
### L3 — No `minimumComments` rule despite review task mentioning it
|
||||||
|
|
||||||
|
- **File:** `src/core/types/giveaway.ts`
|
||||||
|
- **Description:** `FilterRules` does not contain a `minimumComments` field. The task asked to test combinations including `minimumComments`, but the rule is not implemented.
|
||||||
|
- **Consequence:** Organizer cannot require "at least N comments".
|
||||||
|
- **Recommended fix:** Add `minimumComments?: number` to `FilterRules` and enforce it in `applyFilterRules` after deduplication.
|
||||||
|
- **Coordination:** requires type + filter engine change; **not auto-fixed.**
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## INFO
|
||||||
|
|
||||||
|
### I1 — Strong core domain isolation
|
||||||
|
|
||||||
|
- The core layer (`src/core/randomizer`, `src/core/filtering`, `src/core/fsm`) has no imports from Next.js, React, or provider implementations. This is good and should be preserved.
|
||||||
|
|
||||||
|
### I2 — Provider abstraction is clean and testable
|
||||||
|
|
||||||
|
- `SocialMediaProvider` interface (`src/providers/types.ts`) cleanly separates platform specifics from the domain. `VkMockProvider` allows offline testing.
|
||||||
|
|
||||||
|
### I3 — Provably-fair hashing is deterministic and order-independent
|
||||||
|
|
||||||
|
- `computeParticipantsSnapshotHash` and `computeConditionsHash` canonicalize input and produce stable hashes, enabling third-party verification.
|
||||||

|
## Scalability analysis
|
||||||
|
|
||||||
|
### Participant snapshot JSON size estimation
|
||||||
|
|
||||||
|
A single `FilteredParticipant` record contains:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"platformUserId": "123456789",
|
||||||
|
"firstName": "Иван",
|
||||||
|
"lastName": "Иванов",
|
||||||
|
"username": "ivanov",
|
||||||
|
"avatarUrl": "https://.../photo.jpg",
|
||||||
|
"source": "COMBINED",
|
||||||
|
"liked": true,
|
||||||
|
"commented": true,
|
||||||
|
"commentsCount": 3,
|
||||||
|
"reposted": false,
|
||||||
|
"subscribed": true,
|
||||||
|
"eligible": true,
|
||||||
|
"exclusionReason": null
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Approximate serialized size: **250–400 bytes** per participant (avatar URLs dominate).
|
||||||
|
|
||||||
|
| Eligible participants | Snapshot JSON size | Assessment |
|
||||||
|
|---|---|---|
|
||||||
|
| 1 000 | ~0.3 MB | ✅ Safe. Fits comfortably in memory and a `jsonb` column. |
|
||||||
|
| 10 000 | ~3 MB | ✅ Still safe for a single request, but UI table rendering starts to degrade. |
|
||||||
|
| 50 000 | ~15 MB | ⚠️ Heavy. Page load / API response time increases; hashing takes noticeable CPU. |
|
||||||
|
| 100 000 | ~30 MB | ❌ Risky. Exceeds comfortable single-row JSON workload; Next.js API response limits may be hit. |
|
||||||
|
| 500 000 | ~150 MB | ❌ Not viable. PostgreSQL `jsonb` max is ~1 GB, but memory, I/O, and UI become impractical. |
|
||||||
|
|
||||||
|
### Component-by-component assessment
|
||||||
|
|
||||||
|
| Component | 1 000 | 10 000 | 50 000 | 100 000 | 500 000 |
|
||||||
|
|---|---|---|---|---|---|
|
||||||
|
| **Memory (API route)** | < 5 MB | ~30 MB | ~150 MB | ~300 MB | > 1 GB |
|
||||||
|
| **PostgreSQL snapshot row** | 0.3 MB | 3 MB | 15 MB | 30 MB | 150 MB |
|
||||||
|
| **Snapshot hashing (SHA-256)** | < 1 ms | ~5 ms | ~30 ms | ~80 ms | ~500 ms |
|
||||||
|
| **API pagination (VK likes)** | 1 req | 10 req | 50 req | 100 req | 500 req |
|
||||||
|
| **API pagination (VK comments)** | 10 req | 100 req | 500 req | 1 000 req | 5 000 req |
|
||||||
|
| **Subscription checks** | 2 req | 20 req | 100 req | 200 req | 1 000 req |
|
||||||
|
| **UI Participants table** | instant | slight lag | unusable without virtualization | browser crash risk | requires server-side pagination |
|
||||||
|
| **Next.js API response** | < 50 KB | ~300 KB | > 1 MB | > 3 MB | > 15 MB |
|
||||||
|
|
||||||
|
### When does `eligibleParticipants JSON` stop being a good solution?
|
||||||
|
|
||||||
|
**Threshold: ~10 000 eligible participants.**
|
||||||
|
|
||||||
|
Above 10 000, the monolithic JSON snapshot becomes a bottleneck because:
|
||||||
|
1. **Network:** `/api/giveaways/[id]/draw` and related endpoints return the full snapshot or draw result, producing multi-megabyte responses.
|
||||||
|
2. **Memory:** every snapshot read loads the entire list into the Node.js heap.
|
||||||
|
3. **UI:** rendering the participants table without virtualization causes jank or crashes.
|
||||||
|
4. **Hashing:** snapshot hash computation is O(n) on a large string; while still fast, it blocks the event loop.
|
||||||
|
5. **Audit replay:** third-party verification must download the entire JSON to recompute the hash.
|
||||||
|
|
||||||
|
### Recommended long-term architecture
|
||||||
|
|
||||||
|
1. **Normalize snapshot items:** replace `eligibleParticipants Json` with a `ParticipantSnapshotItem` table (or reuse `Participant` with a `snapshotId`). Each row stores one participant; `participantsSnapshotHash` is computed from a streaming sorted cursor.
|
||||||
|
2. **Paginated API:** return only summary counts by default; expose paginated endpoints for participant lists.
|
||||||
|
3. **Background jobs:** for > 10 000 participants, run import and subscription checks in a background worker (e.g., BullMQ / inngest) and update giveaway status asynchronously.
|
||||||
|
4. **Streaming hash:** compute the snapshot hash using a streaming SHA-256 over sorted rows instead of materializing the full JSON string.
|
||||||
|
5. **Cap + warn:** until the architecture changes, enforce a configurable maximum eligible count (e.g., 10 000) with a clear error message and guidance.
|
||||||

# План интеграции VK API для Randomayzer
|
||||||
|
|
||||||
|
> **Контекст:** Randomayzer — Next.js + TypeScript + Prisma + PostgreSQL сервис для проведения доказуемо честных розыгрышей ВКонтакте. В текущей реализации (`src/providers/vk/vk-provider.ts`) используется сервисный токен `VK_SERVICE_TOKEN` и методы `wall.getById`, `likes.getList`, `wall.getComments`, `groups.isMember`. OAuth / VK ID не реализованы.
|
||||||
|
>
|
||||||
|
> **Статус документа:** планировочный, без production-кода. Все факты, которые не удалось подтвердить официальной документацией VK, помечены как `UNVERIFIED`.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Authentication
|
||||||
|
|
||||||
|
Для работы с VK API существуют три типа ключей доступа. Для Randomayzer наиболее подходящим **на старте** является **сервисный ключ** (соответствует текущей реализации `VkProvider`), так как он не требует авторизации пользователя и покрывает базовые сценарии розыгрыша: получение метаданных поста, сбор лайков/комментариев с открытых стен и пакетную проверку подписки на сообщество.
|
||||||
|
|
||||||
|
Расширенные сценарии (проверка репостов на закрытых страницах, получение списка руководителей сообщества, действия от имени сообщества) требуют **ключа пользователя** или **ключа сообщества**.
|
||||||
|
|
||||||
|
### Service Token (сервисный ключ доступа)
|
||||||
|
|
||||||
|
- **Как получить.** В панели управления приложением на [dev.vk.ru](https://dev.vk.ru/ru/admin/apps-list) (раздел **Разработка → Ключи доступа**) либо в кабинете сервиса авторизации VK ID при создании Standalone-приложения/сайта.
|
||||||
|
- **Scope/права.** Права доступа не запрашиваются. Ключ предназначен для работы с публичными данными игр/мини-приложений и методами, не требующими авторизации пользователя.
|
||||||
|
- **Применимые методы.** `wall.getById`, `likes.getList`, `wall.getComments`, `wall.getReposts`, `groups.isMember`, `groups.getMembers` (с ограничениями), `execute` UNVERIFIED.
|
||||||
|
- **Ограничения.**
|
||||||
|
- Работает только с открытыми профилями и открытыми группами.
|
||||||
|
- Не позволяет выполнять действия от имени пользователя или сообщества.
|
||||||
|
- Сбор репостов ограничен политикой приватности VK (закрытые профили не видны).
|
||||||
|
- **Lifetime.** Не ограничен; при компрометации можно перевыпустить в настройках приложения.
|
||||||
|
- **Риски.** Утечка ключа открывает публичные данные приложения. Ключ должен храниться только на сервере, никогда — в клиентском коде.
|
||||||
|
|
||||||
|
### User Token (ключ доступа пользователя / OAuth 2.0 / VK ID)
|
||||||
|
|
||||||
|
- **Как получить.** Через сервис авторизации VK ID (Authorization Code Flow для сервера, Implicit Flow для клиента) или событие `VKWebAppGetAuthToken` VK Bridge в мини-приложениях/играх.
|
||||||
|
- **Scope/права.** Определяются правами доступа, которые пользователь выдал приложению (например, `wall`, `groups`, `friends`). Базовые права (имя, фото, почта) доступны сразу; расширенные требуют подтверждения профиля бизнеса.
|
||||||
|
- **Применимые методы.** Все методы, доступные сервисному ключу, плюс методы, требующие авторизации конкретного пользователя: просмотр закрытых профилей при наличии доступа, расширенная работа со стеной, `groups.get` и т.д.
|
||||||
|
- **Ограничения.**
|
||||||
|
- Требует прохождения пользователем экрана согласия.
|
||||||
|
- Короткий срок жизни (см. ниже), необходимо обновление.
|
||||||
|
- **Lifetime.** **1 час** для ключа, полученного через VK ID / OAuth.
|
||||||
|
- **Риски.**
|
||||||
|
- Необходимость безопасного хранения refresh-токенов и секретов приложения.
|
||||||
|
- Нужно реализовать OAuth flow и обработку отзыва разрешений пользователем.
|
||||||
|
- При передаче в клиент увеличивается риск перехвата.
|
||||||
|
|
||||||
|
### Community Token (ключ доступа сообщества)
|
||||||
|
|
||||||
|
- **Как получить.** В настройках сообщества: **Управление → Дополнительно → Работа с API → Ключи доступа**. Можно создать несколько ключей с разным набором прав. Программно — через OAuth ВКонтакте (Authorization Code Flow / Implicit Flow) либо событие `VKWebAppGetCommunityToken` VK Bridge.
|
||||||
|
- **Scope/права.** Права назначаются при создании ключа (например, `wall`, `photos`, `messages`, `manage`).
|
||||||
|
- **Применимые методы.**
|
||||||
|
- Методы в рамках одного сообщества: `wall.getById`, `likes.getList`, `wall.getComments`, `groups.isMember`, `groups.getMembers` (включая `filter=managers` для получения ролей).
|
||||||
|
- Методы управления сообществом — не требуются Randomayzer на этапе сбора участников.
|
||||||
|
- **Ограничения.**
|
||||||
|
- Действует только в рамках сообщества, для которого выдан.
|
||||||
|
- Получить ключ может только администратор сообщества.
|
||||||
|
- **Lifetime.** Не ограничен; администратор может отозвать ключ в любой момент.
|
||||||
|
- **Риски.**
|
||||||
|
- Утечка ключа с правами `manage` даёт полный контроль над сообществом.
|
||||||
|
- Требует строгого разграничения прав по ключам (принцип минимальных привилегий).
|
||||||
|
|
||||||
|
### Рекомендация для Randomayzer
|
||||||
|
|
||||||
|
| Этап | Рекомендуемый токен | Обоснование |
|
||||||
|
|---|---|---|
|
||||||
|
| MVP / текущая реализация | Сервисный ключ | Без OAuth, серверная работа, публичные посты и лайки |
|
||||||
|
| Проверка репостов в закрытых профилях | Ключ пользователя организатора | Требуется авторизация владельца стены/профиля |
|
||||||
|
| Проверка администраторов/модераторов сообщества | Ключ сообщества | `groups.getMembers filter=managers` доступно с правами администратора |
|
||||||
|
| Массовые розыгрыши 10 000+ участников | Сервисный + пакетирование (`execute`) UNVERIFIED | Высшие лимиты и отсутствие необходимости UI-авторизации |

|
## Tokens
|
||||||
|
|
||||||
|
| Тип токена | Назначение | Доступные методы (для розыгрышей) | Ограничения | Срок жизни | Риски |
|
||||||
|
|---|---|---|---|---|---|
|
||||||
|
| **Сервисный ключ** | Серверные запросы без авторизации пользователя | `wall.getById`, `likes.getList`, `wall.getComments`, `wall.getReposts`, `groups.isMember`, `groups.getMembers` | Только открытые профили/группы; репосты ограничены приватностью; `execute` — UNVERIFIED | Не ограничен | Утечка открывает публичные данные; нельзя передавать на клиент |
|
||||||
|
| **Ключ пользователя (VK ID OAuth)** | Запросы от имени пользователя | Все методы сервисного ключа + методы, требующие авторизации (`groups.get`, доступ к закрытым данным при согласии) | Требуется согласие пользователя; короткий срок жизни; refresh-логика | **1 час** | Хранение секретов/refresh; необходимость OAuth flow; отзыв прав |
|
||||||
|
| **Ключ сообщества** | Запросы от имени сообщества | Методы в рамках одного сообщества, включая `groups.getMembers filter=managers` | Только своё сообщество; нужен администратор для создания | Не ограничен | Утечка ключа с правами `manage` даёт контроль над сообществом |
|
||||||
|
|
||||||
|
### Что каждый токен может и не может делать для розыгрышей
|
||||||
|
|
||||||
|
- **Сервисный ключ**
|
||||||
|
- ✅ Получить метаданные открытого поста.
|
||||||
|
- ✅ Собрать лайки (`likes.getList`) и комментарии (`wall.getComments`).
|
||||||
|
- ✅ Проверить подписку на сообщество (`groups.isMember`).
|
||||||
|
- ❌ Получить список руководителей сообщества (`groups.getMembers filter=managers`) — UNVERIFIED, вероятно требуется ключ сообщества.
|
||||||
|
- ❌ Увидеть репосты на закрытых профилях.
|
||||||
|
- **Ключ пользователя**
|
||||||
|
- ✅ Всё, что умеет сервисный ключ (если профили/группы доступны пользователю).
|
||||||
|
- ✅ Доступ к расширенным данным при наличии соответствующих прав.
|
||||||
|
- ❌ Не даёт прав администратора чужого сообщества.
|
||||||
|
- **Ключ сообщества**
|
||||||
|
- ✅ Все операции в рамках своего сообщества.
|
||||||
|
- ✅ Проверка ролей (`groups.getMembers filter=managers`) — при наличии прав.
|
||||||
|
- ❌ Не применим к постам/группам других организаторов.

## Required VK methods
|
||||||
|
|
||||||
|
| Функциональность | VK Method | Токен | Права / Параметры | Ограничения |
|
||||||
|
|---|---|---|---|---|
|
||||||
|
| Загрузка метаданных поста | `wall.getById` | Сервисный или пользовательский | `posts={owner_id}_{post_id}`, `extended=1` | Возвращает массив объектов `post`; при `extended=1` дополнительно `profiles` и `groups`. Ошибка `104 Not found`, если запись недоступна. |
|
||||||
|
| Сбор лайков | `likes.getList` | Сервисный или пользовательский | `type=post`, `owner_id`, `item_id`, `filter=likes`, `extended=1`, `count` до 1000, `offset` | Максимум 1000 идентификаторов за запрос. При `filter=copies` возвращает пользователей, поделившихся записью, но только если запрос отправляет администратор группы (права редактора и выше) или владелец стены. |
|
||||||
|
| Сбор комментариев | `wall.getComments` | Сервисный или пользовательский | `owner_id`, `post_id`, `extended=1`, `count` до 100, `offset`, `fields` | Максимум 100 комментариев за запрос. При `extended=1` возвращает `profiles` и `groups`. Ошибка `212 Access to post comments denied`. |
|
||||||
|
| Проверка подписки на сообщество | `groups.isMember` | Сервисный, пользовательский или ключ сообщества | `group_id`, `user_id` или `user_ids` (до 500), `extended=1` | При пакетной проверке возвращает массив объектов `{user_id, member}`. При `extended=1` дополнительно `request`, `invitation`, `can_invite`. |
|
||||||
|
| Информация о сообществе / список участников | `groups.getMembers` | Сервисный, пользовательский или ключ сообщества | `group_id`, `count`, `offset`, `fields`, `filter` | `filter=managers` доступно при запросе от имени администратора сообщества; возвращает `role` (`advertiser`, `moderator`, `editor`, `administrator`, `creator`). Максимальное значение `count` — UNVERIFIED. |
|
||||||
|
| Сбор / проверка репостов | `wall.getReposts` | Сервисный или пользовательский | `owner_id`, `post_id`, `offset`, `count` | Возвращает `items` (записи-репосты), `profiles`, `groups`. Закрытые профили не попадают в выдачу без авторизации владельца стены. |
|
||||||
|
| Альтернативная проверка репостов | `likes.getList` с `filter=copies` | Ключ сообщества (администратор группы) или владелец стены | `type=post`, `owner_id`, `item_id`, `filter=copies`, `extended=1` | Возвращает пользователей, поделившихся записью, только при наличии соответствующих прав. |
|
||||||
|
| Проверка администраторов/модераторов | `groups.getMembers` с `filter=managers` | Ключ сообщества с правами администратора | `group_id`, `filter=managers` | Возвращает руководителей сообщества с полем `role`. Недоступно сервисному ключу — UNVERIFIED. |
|
||||||
|
|
||||||
|
### Примечания к таблице
|
||||||
|
|
||||||
|
- Типы токенов для каждого метода определены по цветовым индикаторам в официальном справочнике VK: серый — сервисный ключ, оранжевый — пользовательский, синий — ключ сообщества.
|
||||||
|
- `wall.getById`, `likes.getList`, `wall.getComments`, `wall.getReposts` имеют индикаторы сервисного и пользовательского токенов.
|
||||||
|
- `groups.isMember` и `groups.getMembers` имеют индикаторы всех трёх типов токенов.

## Rate Limit Strategy

> **Важно:** этот раздел описывает только архитектуру и контракты. Код не реализуется в рамках данного документа.
|
||||||
|
|
||||||
|
### Целевая архитектура
|
||||||
|
|
||||||
|
```text
|

VK API

|
||||||
|
```
|
||||||
|
|
||||||
|
`VkProvider` реализует интерфейс `SocialMediaProvider` и делегирует низкоуровневые вызовы `VkClient`. `RateLimiter` и `RetryPolicy` являются отдельными, тестируемыми абстракциями.
|
||||||
|
|
||||||
|
### Контракты / интерфейсы
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Абстракция HTTP-клиента VK API
|
||||||
|
interface VkClient {
|
||||||
|
call<T>(method: string, params: Record<string, unknown>): Promise<VkResponse<T>>;
|
||||||
|
}
|
||||||
|
|
||||||
|
type VkResponse<T> =
|
||||||
|
| { response: T; error?: never }
|
||||||
|
| { response?: never; error: VkError };
|
||||||
|
|
||||||
|
interface VkError {
|
||||||
|
error_code: number;
|
||||||
|
error_msg: string;
|
||||||
|
}
|
||||||
|
|
||||||
|
// Ограничение скорости
|
||||||
|
interface RateLimiter {
|
||||||
|
acquire(tokenType: VkTokenType, cost?: number): Promise<void>;
|
||||||
|
updateLimits(tokenType: VkTokenType, remaining: number, resetAt: Date): void;
|
||||||
|
}
|
||||||
|
|
||||||
|
type VkTokenType = 'service' | 'user' | 'community';
|
||||||
|
|
||||||
|
// Политика повторных попыток
|
||||||
|
interface RetryPolicy {
|
||||||
|
execute<T>(task: () => Promise<T>, context: RetryContext): Promise<T>;
|
||||||
|
}
|
||||||
|
|
||||||
|
interface RetryContext {
|
||||||
|
maxAttempts: number;
|
||||||
|
isRetryable: (error: VkError) => boolean;
|
||||||
|
computeDelay: (attempt: number, error: VkError) => number;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Exponential backoff
|
||||||
|
|
||||||
|
- Начальная задержка: 500–1000 мс.
|
||||||
|
- Множитель: 2 (с jitter до 20–30 %), чтобы избежать «thundering herd».
|
||||||
|
- Максимальная задержка: 30–60 с.
|
||||||
|
- Общее время ожидания должно быть ограничено (например, 5 минут на одну операцию), после чего ошибка прокидывается вызывающему коду.
|
||||||
|
|
||||||
|
### Retryable vs non-retryable errors
|
||||||
|
|
||||||
|
| Код ошибки | Статус | Действие |
|
||||||
|
|---|---|---|
|
||||||
|
| `6` Too many requests per second | Retryable | Повторить после backoff, уменьшить скорость |
|
||||||
|
| `9` Flood control | Retryable | Увеличить задержку, возможно — запросить капчу UNVERIFIED |
|
||||||
|
| `10` Internal server error | Retryable | Повторить с backoff |
|
||||||
|
| `29` Rate limit reached | Retryable/Non-retryable | Дневной лимит; повторять с большим интервалом либо прекратить |
|
||||||
|
| `15` Access denied | Non-retryable | Закрытая группа/профиль; зафиксировать в аудите |
|
||||||
|
| `18` User was deleted or banned | Non-retryable | Исключить пользователя из выборки |
|
||||||
|
| `30` Private profile | Non-retryable | Исключить с причиной `PRIVATE_PROFILE_OR_NO_REPOST` |
|
||||||
|
| `104` Not found | Non-retryable | Пост не найден |
|
||||||
|
| `212` Access to post comments denied | Non-retryable | Ограничены комментарии |
|
||||||
|
| `232` Reaction can not be applied | Non-retryable | Ошибка параметров `likes.getList` |
|
||||||
|
|
||||||
|
### Rate limit handling
|
||||||
|
|
||||||
|
- Лимиты по типу токена (подтверждено документацией VK):
|
||||||
|
- Пользовательский ключ: **3 запроса/сек**.
|
||||||
|
- Ключ сообщества: **20 запросов/сек**.
|
||||||
|
- Сервисный ключ: от **5 до 60 запросов/сек** в зависимости от количества пользователей приложения.
|
||||||
|
- Рекомендуется использовать token-bucket per `VkTokenType` с консервативным начальным значением (например, 50 % от заявленного лимита) и адаптацией при получении ошибки `6`.
|
||||||
|
- Все запросы одного розыгрыша должны учитывать общий bucket, даже если они выполняются в разных корутинах/процессах.
|
||||||
|
|
||||||
|
### Pagination strategy
|
||||||
|
|
||||||
|
- `likes.getList`: `count=1000`, увеличивать `offset` на 1000 до достижения `response.count`.
|
||||||
|
- `wall.getComments`: `count=100`, увеличивать `offset` на 100.
|
||||||
|
- `groups.isMember`: батчировать `user_ids` по **500** ID.
|
||||||
|
- `groups.getMembers`: UNVERIFIED — предположительно `count` до 1000, но в документации точное максимальное значение не указано.
|
||||||
|
- При изменении данных во время pagination (например, пользователь удалил лайк) возможны дубли или пропуски. Для розыгрышей рекомендуется фиксировать `snapshotTime` и игнорировать изменения после него.
|
||||||
|
|
||||||
|
### Batching через `execute`
|
||||||
|
|
||||||
|
- Метод `execute` позволяет выполнять код на серверах VK (VKScript).
|
||||||
|
- Предполагаемые лимиты (UNVERIFIED): до 25 вызовов API внутри одного `execute`.
|
||||||
|
- Потенциальная эффективность:
|
||||||
|
- `likes.getList`: 25 × 1000 = до 25 000 лайков за 1 HTTP-запрос.
|
||||||
|
- `groups.isMember`: 25 × 500 = до 12 500 проверок подписки за 1 HTTP-запрос.
|
||||||
|
- `wall.getComments`: 25 × 100 = до 2 500 комментариев за 1 HTTP-запрос.
|
||||||
|
- **Риски:** один упавший под-вызов внутри `execute` может прервать весь батч; требуется гранулярная обработка ошибок и fallback на последовательные запросы.
|
||||||
|
|
||||||
|
### Timeout и cancellation
|
||||||
|
|
||||||
|
- Установить разумный network timeout для VK API: 30–60 с.
|
||||||
|
- Поддержать `AbortSignal` / cancellation token на уровне `VkClient`, чтобы длительные операции сбора участников можно было прервать из UI.
|
||||||
|
- При отмене сохранять уже загруженные данные и статус прогресса.

||||||

|
1. **Сейчас** (`VkProvider`) используется только сервисный ключ `VK_SERVICE_TOKEN`. Это корректный MVP-подход: без OAuth, серверная работа, базовый сбор лайков/комментариев и проверка подписки.
|
||||||
|
2. **Дальнейшее развитие** требует выбора между:
|
||||||
|
- **OAuth VK ID** для получения пользовательского токена организатора (для закрытых профилей и расширенных прав);
|
||||||
|
- **ключом сообщества** (для проверки ролей админов/модераторов и работы строго в рамках одного сообщества).
|
||||||
|
3. **Перед внедрением OAuth** необходимо отдельно спроектировать поток авторизации, хранение токенов, refresh-логику и аудит действий от имени пользователя.
|
||||||
|
4. **Rate limiting** должен быть вынесен в отдельные слои `RateLimiter` и `RetryPolicy`, чтобы `VkProvider` оставался чистым адаптером `SocialMediaProvider`.
|
||||||
|
5. Все неподтверждённые официальной документацией числовые лимиты (`execute`, максимальный `count` для `groups.getMembers` и др.) помечены `UNVERIFIED` и требуют проверки в процессе разработки.
