Signal origin & transmission lore
The fourth archive shell was created automatically. No operator requested it. The Selenophone opened the record, assigned it a TX number, and began reserving lunar memory blocks for a transmission that has not arrived yet.
Initial echoes do not point toward an alternate city, nation, or surviving civilization. They point outward: past the registered branches of human history, past catalogued extinction events, past the part of the archive that still uses dates.
Current terminal behavior suggests the machine is not searching for TX_04. It is waiting for TX_04 to remember the machine first.
