Forward and reflected
throughVoid(n) = 1 − n mod 9 is an involution fixed only at 5. It maps the forward reading onto its mirror — a re-valuing, not a reversal. Both lines are computed from one constant.
Sequence dual
The vortex sequence, its reflection through the void, and a kernel that computes both rather than asserting them.
The arithmetic here is exact and checkable. The presentation layer built on top of it — colour mappings, a 432 Hz reference pitch — is a chosen convention, not a discovery. Those two things are kept apart deliberately, because the arithmetic is strong enough that dressing it as physics would only make it easier to dismiss.
hue = 36d; the CMYK transform; A432 as reference pitch (the ISO 16 standard is 440 Hz).Every generated page on this site carries a content-addressed receipt folded over its own body, so a change to what a page says moves its stamp.
npm run checkThat runs the kernel smoke tests, the ambient-Math ban, the bundle and skills seals, regenerates every projection, and re-derives the next development tip. It fails closed.
