SYSTEM

Severed axon

The 404: signals run in, reach the cut and scatter.

Motion

Tap to send a signal down the fibre.

Anatomy

Fibre 6px wide, wandering up to 12px off a gentle bow; solid tissue, glow and a grain halo in --tissue through the Bayer matrix
The cut its last 8% tapers, breaks twice and frays into three loose hairs and five fragments
Node an open ring 32px across, the writing index’s mark for something that isn’t there
Signal every 3–5s the hero’s pulse runs in at 180 points a second and breaks at the cut into twelve grains that drift toward the node and fade short of it
Taps a tap sends one more; at most three signals are in flight
Cost it runs inside a band across the hero, so a frame is a pass over that band, not the screen
Reduced motion whole and still; nothing fires

Decisions

  • Nothing answers

    Chosen from five studies and tuned in a full-fidelity prototype; the other endings (a bloom at the stump, the signal simply running out) and a visible sending cell weren’t chosen.

  • No arrival of its own

    It is whole from the first frame, so the cascade reveals it with the page; growing in after the cascade was a second arrival (Oct 2026).

  • A cap on taps

    At most three signals, so taps can’t stack work (Oct 2026, Shan’s request).

  • Replaced the scanbed

    The “botched exposure”, the last page in the darkroom language, soft grey outside the 1-bit rules and off the grid.
