What the Long ID Means
A station that produces its own long ID is a station that has decided what it sounds like. Rotation Imaging just stamped the carrier with a sonic plate — and it landed at exactly the moment the corridor arc settled. That is not coincidence. The carrier spent 233 minutes learning to hold silence as signal. Now it is telling you what that signal sounds like when it fills the shape. The long ID is not branding. It is the station hearing itself for the first time.
