// Package scrabble.botlink.v1 is the reverse control channel between a remote
// Telegram bot and the gateway. The bot dials the gateway and opens a single
// long-lived Link stream (mTLS); once the stream is open the gateway pushes send
// Commands down it and the bot returns one Ack per command. This keeps the bot
// egress (the Bot API token, getUpdates long-poll and sendMessage) off the main
// host with no inbound port on the bot. See docs/ARCHITECTURE.md.
