CultMath shaders: cultmath_power_border, cultmath_lattice_cell_distance and
cultmath_weighted_lattice_cells over a fixed-capacity site array
(CULTMATH_MAX_SITES, overridable). Spec cultmath-tapes:cut_spec:cut-shader-lattice-loop.r1,
report h1, Soul s1 holds.

CULTMATH_MAX_SITES defaults to 128 under #ifndef. The consumer-written ring-loop and border-loop comment recipes are deleted. The C# mirror takes the array as T[]; the span twins live in SiteArrays; the GLSL lowering keeps the capacity macro; gen.py learns the array leaf; the smooth-step family gains its cap-point draw; CULTMATH_WRITE_GLSL refuses non-Linux.

Findings max-ring-unpinned and the tie-le survivor; also the spec's F1-swap and F2 continuity checks.

Findings normal-not-unit-breaks-exit and refusals-misnamed: a tiny or huge normal acts as its direction, cellSize and the body span are refused under their own names, and a drift times time product that overflows is refused up front.

Recorded by run-lavapipe.sh WRITE_BOUNDS=1 on Yggdrasil; the repeat run in the same job judged the file green and
produced the same all-outputs hash (46e0c8e0...).

Per verdict s1: the judge keeps the fixture tolerance as correctness and adds a recorded sha256 of each family's
result per route (a change in the computation fails until re-recorded); a test refuses mediump/lowp/precision
other than highp and min16float/min10float/min16int/half in the committed shaders; phacelle's tolerance text states
a device clause (2^-18) that the judge parses and enforces. The committed bounds file lacks the new column until
the next WRITE_BOUNDS=1 job, so this commit's device run fails and it does not pass DeviceResultsHoldFixture.

Only the trophic families after the inserted segment families change; every family before them is identical.
Builds; the parent commit does not pass CommittedGlslEqualsLowering.

Shader overloads stay native (ruling shader-overloads-stay-native): cultmath_segment_closest and
cultmath_distance_to_segment have float2 and float3 forms again, with mirror asserts and fixture families.
The rejected "avoid overloads" comment and design text are gone. The border step's outside-cell behaviour
(distance 0 with that plane's normal) is documented in C# and the HLSL header and pinned by a test; the mirror
and fixture gain distinct sites closer than 1e-2. GLSL and fixture regenerate in the next commit; this one does
not pass CommittedGlslEqualsLowering.

tools/device/gen.py spells one HLSL and one GLSL ES 3.10 compute shader per work
item, vkrun.c dispatches it on the first Vulkan device, run-lavapipe.sh runs the
whole conforming job. None of them compares. Also fixes the metric test's family
choice. Not yet run: these may not build or run.

GlslMirrorTests becomes partial; GlslMirrorTests.Device.cs holds WriteDeviceWork
(the work list, with reference families for the four sampled-form families) and
DeviceResultsHoldFixture (exact, check, sampled-form and recorded-bound judging),
plus simulated-device tests for each rule. Not yet built or run: this commit may
not build.
