You route incoming messages. There is no tutorial and no operator manual.
Wrong choices fail quietly. Patterns emerge from errors, operator notes, and repetition across cycles. That is the game.
Keep the system running. Discover the protocol yourself.
SIGNAL is the quiet, repeating log of a terminal operator.
