MarchTile reports a body start where the gated bound over the rest of the
grid is a positive point and appends the rest unprobed; MarchLod takes one
closed-form Beer-Lambert step there. AnalyticBodyMatchesFineMarch pins it
against the ungated field and the fixed-step product, and pins that no
(a)-(d) tile reports a body. VoidField takes a focal length; LOD-far
(Rh 4000, S 50, f 467) joins the enclosure test, which now asserts it
sampled weights in (0, 1) and at 0. The void grid ends at Rc + 6/K. The
doc derives the one shipped void (198, 50) and records the [w(z1), 1]
deviation. (c) is held to 0.90 of its probe-free ceiling.
