Add a second standalone promo bot to the bot container (answers /start with a localized message + a URL button into the main bot's Mini App) and gate write access in a channel's linked discussion chat: grant on join when the Telegram user is registered and neither admin-suspended nor holding a new chat_muted role, and revoke/grant on the matching moderation change for a member currently in the chat. Eligibility (registered AND NOT suspended AND NOT chat_muted; the game suspension dominates) is resolved once in the backend and reached two ways: the bot's join-time unary ResolveChatEligibility over the existing mTLS bot-link, and a backend chat_access_changed event -> gateway -> ChatGate command (idempotent; a temporary-block-expiry sweeper may over-emit). The bot guards the block/unblock path with getChatMember, since bots cannot list members. A web_app button cannot open another bot's Mini App (it signs initData with the sending bot's token), so the promo button is a t.me ?startapp URL reusing the UI's VITE_TELEGRAM_LINK. The bot must be a chat admin with the restrict-members right and chat_member in its allowed updates. No schema change: chat_muted reuses the data-driven account_roles table.
