Backend:
- max_ai_messages_per_day + max_ai_tokens_per_day on User model (nullable, override)
- Migration 008: add columns + seed default settings (100 msgs, 500K tokens)
- usage_service: count today's messages + tokens, check quota, get limits
- GET /chats/quota returns usage vs limits + reset time
- POST /chats/{id}/messages checks quota before streaming (429 if exceeded)
- Admin user schemas expose both limit fields
- GET /admin/usage returns per-user daily message + token counts
- admin_user_service allows updating both limit fields
Frontend:
- Chat header shows "X/Y messages · XK/YK tokens" with red highlight at limit
- Quota refreshes every 30s via TanStack Query
- Admin usage page with table: user, messages today, tokens today
- Route + sidebar entry for admin usage
- English + Russian translations

# Phase 10: Per-User Rate Limits — Subplan
|
|
|
|
## Goal
|
|
|
|
Enforce per-user daily AI message limits with admin-configurable defaults, per-user overrides, usage tracking, and frontend quota visibility.
|
|
|
|
## Prerequisites
|
|
|
|
- Settings table + service, admin panel, chat/message system
|
|
|
|
---
|
|
|
|
## Tasks
|
|
|
|
- [x] **10.1** Add `max_ai_messages_per_day` nullable int to User model. Migration 008 (or 009).
|
|
- [x] **10.2** Seed `default_max_ai_messages_per_day` setting (default: 100).
|
|
- [x] **10.3** Create `backend/app/services/usage_service.py`: get_user_message_count_today, get_user_daily_limit.
|
|
- [x] **10.4** Enforce limit in `POST /chats/{id}/messages` before streaming (429 if exceeded).
|
|
- [x] **10.5** Add `GET /chats/quota` endpoint (used, limit, resets_at).
|
|
- [x] **10.6** Expose max_ai_messages_per_day in admin user schemas + service.
|
|
- [x] **10.7** Add `GET /admin/usage` stats endpoint (per-user daily counts).
|
|
- [x] **10.8** Frontend: show quota in chat header ("X/Y messages today").
|
|
- [x] **10.9** Frontend: admin usage page.
|
|
- [x] **10.10** Frontend: handle 429 in chat, routes, sidebar, i18n.
|
|
- [x] **10.11** Tests + verification.

|
|
4. Chat header shows usage counter
|
|
5. Admin usage page shows per-user stats
|
|
6. All UI text in en/ru
