A domain built so span integration holds by construction: sums of
nonnegative compact ellipsoid kernels in a mass-conserving multiplicative
cascade, per-kernel affine warp, all nonlinearity moved into placement.
Measured on Yggdrasil against the shipped void and wells, with a physical
reference (Beer-Lambert, single scattering with HG).

Measured on the shipped void and the Aetheria wells at warp 60: affine warp
spans, simplex cells and lattice points per span, exact-against-march cost and
error per octave, high-octave variance, clamp crossings and transmittance
error; plus Aetheria's triangle noise. Verdict: exact integration does not
beat sampling for optical depth on either field.

Eyes pass for variants❓read-only-record-signal. ORMs, embedded
stores, serializers, file systems and object stores; signal shape and
time-of-check pitfalls for each, with evidence pointers.
