Telegram

The first channel: Telegram chats where the people it knows talk to the host.

• Talking: a message from one of its people in one of its chats is a question to the chief, asked as that person, and the answer goes back to the chat.
• Approvals: a board decision that waits for a person is posted to the approvals chat with what, why, the risk, and Approve / Decline buttons. Approving acts as the person who pressed; anyone the channel does not act for changes nothing.
• Notifications: webhooks and the scheduler tell a chat at once when something happens.

The bot token is a secret setting; the people it acts for are configured by a person - a module acts for a person only when that person was named in its settings.
