A fixed centerline carrier fires through a 27-gate mountain bore while three phase waves orbit it. At gate 27, the packet compresses into 0, then reappears as 27 on the far side.
The white carrier remains on the bore axis. It is the coherence reference: every colored wave rotates around it, but the center pulse never leaves the center.
Three rails wrap around the carrier like a wave-beam helix. They represent phase, pressure, and envelope timing.
The end of the tunnel is a singular gate. The packet folds to zero, then exits into a new 27-count domain.
