New platform/telegram connector (own container, bot token only there): - go-telegram/bot long-poll loop: /start deep-links + Mini App launch button. - gRPC API pkg/proto/telegram/v1 (Telegram service): ValidateInitData, Notify (renders a localized message + deep-link button), SendToUser/SendToGameChannel (admin, wired in Stage 10). Generic methods are platform-agnostic (external_id). - Bot API base override for Telegram's test environment; Dockerfile + compose (VPN sidecar, no public ingress); README. Gateway: - initData validation relocated from the gateway into the connector; the gateway calls ValidateInitData over gRPC (GATEWAY_CONNECTOR_ADDR), drops the bot token, and deletes internal/auth. - Out-of-app push: runPushPump routes events whose recipient has no live in-app stream to connector.Notify, gated by /internal/push-target + the in-app-only flag (race-free de-dup); HasSubscribers added to the push hub. Backend: - Migration 00007 accounts.notifications_in_app_only (default true) + jetgen. - ProvisionTelegram seeds a new account's language/display name from the launch fields; IdentityExternalID reverse lookup; /internal/push-target handler. UI: - Telegram Mini App launch: detect initData, apply themeParams, authTelegram, route the deep-link start_param (g/i/f); /telegram/ guard redirects outside Telegram. Vite relative base + telegram-web-app.js. In-app-only profile toggle; share-to-Telegram link for a friend code. Vitest + Playwright coverage. Wire/docs/CI: fbs Profile/UpdateProfileRequest gain notifications_in_app_only (Go + TS); go.work uses ./platform/telegram; go-unit.yaml covers it; PLAN, ARCHITECTURE, FUNCTIONAL (+ru), UI_DESIGN, READMEs updated.
