Backend/Web/Android Parity Snapshot (2026-03-09)

1) Backend vs Web

Backend покрывает web-функционал почти полностью (~95-100%):

• auth: login/refresh/me, register, verify-email, resend verification, request/reset password, sessions, 2FA
• chats: list/detail, saved, discover, create/join/leave, members/bans, title/profile, pin/archive, invite-link, notifications, clear/delete
• messages: list/send/edit/delete, status, search/thread, forward/bulk, reactions
• media: upload-url, attachments create/list
• realtime: websocket + typing/read/delivered/ping-pong
• users: search/profile/blocked/contacts
• search: global search
• notifications: list

Вывод: текущие проблемы в основном на стороне клиентской интеграции/UX, не backend-contract.

2) Web endpoints not yet fully used on Android

• GET /api/v1/messages/{message_id}/thread
• GET /api/v1/search (single global endpoint; Android uses composed search calls)
• Contacts endpoints:
  • GET /api/v1/users/contacts
  • POST /api/v1/users/{user_id}/contacts
  • POST /api/v1/users/contacts/by-email
  • DELETE /api/v1/users/{user_id}/contacts
• GET /api/v1/notifications
• POST /api/v1/auth/resend-verification

3) Practical status

• Backend readiness vs Web: high
• Android parity vs Web (feature-level): ~82-87%

4) Highest-priority Android parity step

Завершить следующий parity-блок:

• GET /api/v1/messages/{message_id}/thread
• единый GET /api/v1/search для полнофункционального Telegram-like поиска
• contacts API (/users/contacts*) + экран управления контактами
