The bot — paired, locked, and silent to strangers

The channel gets built — locked before it's useful, the reach era opening the way every capability has. The member creates the bot with BotFather (two minutes, in the Telegram app) and the token goes straight down the Module 9 key path, because the token IS the bot and leaked tokens are a scanned-for incident class. The build lands the poller — long polling, outbound-only, nothing ever knocking on the member's door — with the channel switch born in the same diff (polling stopped, dead both ways, state visible), and pairing: a one-time code shown in the app, sent by the member from their own account, pinning that chat ID as the owner. The proof is deliberately boring and deliberately complete: the owner's hello gets a fixed acknowledgement with no model anywhere near the channel; everyone else — including the member themselves before pairing — gets silence and a log line, because a reply confirms a live bot and silence gives a scanner nothing. A locked door, proven as a door before it carries a single real answer.
