Service-agnostic refinement of the owner's idea: the sign-in service returns a set of supported game languages with the user identity, and the lobby gates the New Game variant choice by it (en -> English; ru -> Russian + Эрудит). - Connector hosts two bots in one container (one per service language, each its own token + game channel; the same telegram_id spans both). ValidateInitData tries each token and returns the validating bot's service_language + supported_languages. Per-language config (TELEGRAM_BOT_TOKEN_EN/_RU, channels). - supported_languages rides the Session (fbs, session-scoped, not persisted); the UI offers only the matching variants on New Game — gating only the START of a new game (auto-match + friend invite), not accept/open/play; backend does not enforce. - service_language persisted (accounts.service_language, migration 00010, written every login, last-login-wins) and routes the user-facing Notify push back through the right bot (push-target coalesces with preferred_language). - Admin SendToUser/SendToGameChannel gain an operator-chosen language selector in the console (unrelated to ValidateInitData). - Non-Telegram logins carry the gateway default set (GATEWAY_DEFAULT_SUPPORTED_LANGUAGES, all variants). Wire (committed regen): ValidateInitDataResponse +service_language +supported_languages; Session +supported_languages; SendToUser/SendToGameChannel +language. Docs (ARCHITECTURE/FUNCTIONAL/_ru/READMEs) + PLAN updated; stage marked done.

// Package connector is the backend's gRPC client for the Telegram platform
|
|
// connector side-service. The admin console uses it to send operator broadcasts:
|
|
// a direct message to one user, or a post to a game channel. Each broadcast
|
|
// selects the delivering bot by language (an operator choice, since the connector
|
|
// hosts one bot per service language). The connector lives on the trusted internal
|
|
// network, so the connection uses insecure (plaintext) transport credentials
|
|
// (docs/ARCHITECTURE.md §12). It mirrors gateway/internal/connector, narrowed to
|
|
// the two broadcast methods the admin surface needs.
