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.
