A Telegram group bot, ported from Python (aiogram + LangChain) to TypeScript on Val Town (Deno + grammY). It only responds inside a configured allowlist of groups.

All text commands accept the text either as an argument (/ai привет) or by replying to a message.

Command	What it does
/t	Fixes wrong keyboard layout (RU↔EN transliteration), shows original struck-through
/ai	Asks Groq for an assistant reply (in Russian)
/argue	Generates aggressive counterarguments to the target message
/google, /g	Returns a Google search link for the text
/current_map, /cm	Apex Legends map rotation (ranked default, battle_royale/br, ltm)

1. Create a bot via @BotFather and grab the token.
2. Set the environment variables below.
3. The webhook registers itself automatically on the first request to the HTTP endpoint (open the val's URL once, or just message the bot).

Key	Required	Description
TELEGRAM_TOKEN	yes	Bot token from @BotFather
GROQ_API_KEY	yes	Groq API key (for /ai and /argue)
MOZAMBIQUE_API_KEY	yes	mozambiquehe.re key (for /current_map)
GROQ_MODEL	no	Defaults to deepseek-r1-distill-llama-70b
ALLOWED_GROUPS	no	Comma/space-separated negative group chat IDs the bot replies in
TARGET_ACCOUNTS	no	Comma/space-separated positive user IDs that get the extra /argue jab

Rendering mermaid diagram...

• main.ts — HTTP webhook handler + grammY command wiring
• config.ts — env var parsing/validation (was the pydantic Settings)
• keyboard.ts — RU↔EN keyboard-layout transliteration
• llm.ts — Groq chat helpers (replaces LangChain ChatGroq)
• maprotation.ts — Apex map rotation lookup

• aiogram → grammY: middleware, command handlers, and reply-to logic map over directly. Long polling is replaced by a self-registering webhook, which is how bots run on Val Town.
• LangChain + ChatGroq → OpenAI SDK: Groq exposes an OpenAI-compatible API, so llm.ts uses npm:openai pointed at https://api.groq.com/openai/v1. The <think>…</think> stripping for deepseek-r1 is preserved.
• pydantic → plain validation in config.ts (positive target accounts, negative group IDs).
