`add channel <type>:<id>` appends an existing artifact to `channels`, by type and id, and never touches a number. At `deploy`, `wireChannels` in `channels/wire.ts` points the artifact's webhook at the function and remembers the previous value, and one route for it goes into the list passed to `channelRoutes` in `.telnyx/index.ts`.

`channels/index.ts` serves every route at `/webhooks/<type>/<id>` and verifies each webhook against the account's public key before reading it. A `messaging_profile` route runs `messagingWebhook`, a `call_control_application` route runs the call handler, and an `email_domain` route runs `emailWebhook`.

> [!WARNING]
>
> **Beta.** A `texml_application` channel is declared and validated, but its handler is not implemented yet. A webhook to it answers 501.
