SPIRV-Cross renames members matching GLSL builtins, so the source names change. Resolver and JSON writer accessors follow the members; the wire (positional MessagePack, JSON keys) is untouched in this commit. The committed GLSL is stale until its regeneration commit, so CommittedGlslEqualsLowering fails here.

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.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
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.

The earlier version read past a one-element array and passed under the mutant by hitting a non-finite site.

power_border_step/power_border give the exact distance to the owner's power cell boundary: the least radical-plane
distance over every other site, built from the offset and (w1-w2)(w1+w2) so it does not cancel. site_cells_border is
documented as the two-winner bisector distance. Cell spans refuse non-finite positions, queries and spans over 2^24.
segment_closest is public in C#; the HLSL segment functions are 3D only (no new overload sets). Tests added.
Does not build the GLSL checks: CultMath.glsl and glsl-parity.json are regenerated in the next commit.

Regenerated with CULTMATH_WRITE_GLSL=1 on Yggdrasil; the fixture adds seven families and deletes no line.

span_slack and af_snoise each spelled 2^-14 (value) and 2^-12 (gradient) inline, in C# and
HLSL. Both now read the constants beside SNOISE_HESSIAN (math.Affine.cs, CultMath.Affine.hlsl,
Unity copies), so a device-judged widening moves every reader. Bits unchanged. The test
oracles in AffineTests and GlslMirrorTests read the constants; a new test pins af_snoise's
allowance to span_slack's terms. span_slack's comment no longer claims it is the only
allowance. Does not build green yet: CultMath.glsl is not regenerated in this commit.

EveryMirrorFunctionMatchesCSharpMath compared both new twins bit for bit against the C# seam;
only its pinned count of mirrored functions moves from 125 to 127. Builds.

Generated by CULTMATH_WRITE_GLSL=1 on Yggdrasil (dotnet/sdk:10.0) at 5ccbb094; the fixture
diff is additions only, every earlier family byte-identical. Builds.

Four coordinate-band snoise_grad / snoise_hessian families with Verify AssertSpanAllowance,
SpanAllowanceCoversReadsAlongTheSpan, NoiseBoundTests.GradDouble and its pin, design.md
paragraph. The fixture and CultMath.glsl are regenerated in the next commit; this one compiles.

The additive 1e-9 absorbed the whole exact departure at scales 1e-4 and 1e-2 (1e-11 to 1e-9),
so dropping the value allowance's absolute term 2^-14 survived the test. The tolerance is 1e-13.
Test only; builds.

CultMath.glsl gains the three structs and cultmath_span_stage/fbm/ridged by the lowering; the fixture
gains the two span families after the last one, earlier families byte-identical (0 deleted lines).
Builds; CultMath.Tests 452 passed at this tree.
