The inherited R19 switch and measured DNA γ

The nose volume inherits two primitives byte-identical to the eye and ear seeds: the R19 switch ds/dt = γ·s − s³ + h and the DNA reading γ plus A4 shape. It inherits no wave module, because smell has no wave. 20 olfactory master genes are measured from NCBI promoters, γ never fitted.

The foundation is the shared R19 bistable switch and a two-layer DNA reading (γ LEVEL + A4 SHAPE) over 20 olfactory master genes, with corr(γ, GC) = 0.998. No wave/angle module is inherited — smell's stimulus is a molecule, not a wave.

The two inherited primitives — and the one that is missing

The volume inherits exactly two things, byte-identical to the eye/ear sibling seeds: the R19 bistable switch ds/dt = γ·s − s³ + h, and the DNA reading that measures each gene's promoter as a stiffness LEVEL γ plus an orthogonal SHAPE (the A4 coordinate). Nothing here is re-derived.

What is not inherited is a wave/angle module. Vision and hearing read a wave as a single physical place; smell has no wave, so no such module carries over. That absence is the volume's first honest structural statement, not an omission.

The measured atlas — 20 olfactory master genes

Every γ below is measured from public NCBI promoters (GRCh38) and cached so the reading reproduces offline bit-for-bit; γ is measured, never fitted. The reading correlates with GC content at corr(γ, GC) = 0.998, and all 20 genes carry a non-trivial A4 SHAPE — the regime where reading γ alone would be lossy.

These genes split into four groups by atlas node: the transduction cascade (6 genes), the olfactory-receptor panel (7 genes), the OSN-identity organisers (3 genes), and the congenital-anosmia genes (4 Kallmann genes). The chapters that follow read each group through the same R19 switch.
