The cyclic step in Ashima's 3D simplex degenerates on the lattice diagonals,
including the origin and every (t,t,t). The fix is one strict compare, giving
simplexnoise1234's total tie order. Probes show it is bit-identical off the
z = x tie set and continuous on it. SNOISE_LIPSCHITZ re-measures to 7.9640074,
and SNOISE_HESSIAN does not move. Merge order: snoise-tie first, then the
affine branch merges main.

(c)'s wells are 1.1-2.5x the 60-unit noise band deep; a 10x well (depth and
half-depth radius 600) measured on the scratch probe: interval already skips
most empty space, affine gains 1.14x/1.16x over the centred interval. (c)
becomes the deep well; the mass-derived wells stay as a printed row.

Resolves Soul's five findings on cut-interval-ops.h2 and carries the rulings
operator-wells-contract-vs-ceiling and operator-analytic-wall-body. glsl-lowering
r2 and site-ground r3 now depend on interval-ops r3; the site-ground spec names
the one shipped void with (Rc, e) derived from (Rh, S) and the body-start word.

The march is footprint-aware: step = max(k z theta_px, min(S/4, lambda_fine/2)),
one smooth weight per octave, the bound enclosing the truncated field. The
cavity cost model is a grid, not a number; the shipped point needs about 6
steps and 12 snoise per pixel against about 35 fixed steps.

Ruling operator-void-true-cavity: the void is a 3D hollow in a cloud volume,
not the 2021 bowl. The outer volume is an unbounded fill so every ray ends in
a wall; Rc grows to 640 so the hollow (198) holds the camera at 186. With no
sky the evaluation ratio for the shipped scene is predicted 1.0-1.2x; the
pre-pass's gain there is sample placement (2.0-2.6x), raised as Q8.

Ruling operator-ground-void-brush answers Q6 outside the options. The
original main menu's brush, floor, sun, orbit, camera follow, authored light
and stardust rule are read from Aetheria at e6181c11 and carried in their
units; the lighting is the original's analytic pulse made 3D; the TAA
reprojects by camera and flow; the saving test gains the void scenario and
asserts 2x on it.

Revision 2 specs for the two CultLib cuts of cultmath-tapes, as follow-ups on
hands/cultmath-interval-ops (c9bd003b) and hands/cultmath-glsl-lowering
(5ae207e8), under the rulings operator-tile-amortized-march,
operator-split-phacelle, operator-compiler-downloads and
self-exp-measure-in-site, and the operator's challenge to the march.

Folds in the operator's rulings: Q1 cultmath-tapes, Q2 samples then
resolution, Q3 the shader owns a dynamic ground and the CSS wash is sampled
from its result. The nebula is flow-warped (two-phase flow map) with one
flow texture owning motion for the warp, the TAA motion vectors, the hue and
the stardust. Interval culling encloses the warp by enlarging the ball;
interval-ops gains that test. New fourth cut site-stardust: stateless
instanced particles plus an opacity-driven gather on the stardust layer, the
web form of the raymarch-driven DoF. Budget re-checked: the full stack lands
a mid-range phone at S = 4-6, not 8. Docs only.

Three cuts under a proposed cultmath-tapes campaign: a textual HLSL -> GLSL
lowering pinned by test, interval ops with enclosure tests and a committed
Lipschitz constant for snoise, and the site's per-pixel interval-culled,
TAA-accumulated cloud ground driven by body tokens with the CSS wash as the
fallback. Docs only.
