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.

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.

Verdicts cut-stage-shaders-device.s1/s2 hold. main's interim changes are Rust packages only (cultnet-rs, cultcache-rs, cultmesh-rs), disjoint from the verified C#/shader tree.

Generated by CULTMATH_WRITE_GLSL=1 on Yggdrasil; glsl-parity.json is unchanged (the af and
span families keep their bytes). Builds.

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.

cultnet-rs 0.2.0: every received MessagePack byte decodes once through
cultcache-rs's door; the dynamic document lane is parked at
parked/cultnet-rs-dynamic-document-lane; one decoder per message family;
duplicate keys refused; refusals name schema and fields, never values;
cultmesh-rs 0.2.0. Cut cultnet-rs-door r2, held by Soul s1-s3.

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

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 inline rounding and the three allowance literals of span_stage and cultmath_span_stage
move into internal span_rounding / span_slack and their HLSL twins; operations and order are
unchanged. CultMath.glsl is not regenerated in this commit, so
GlslMirrorTests.CommittedGlslEqualsLowering fails here; it compiles.

Raw v1 is decoded by the enum's derive alone (SnapshotResponseRawV1Rows,
the v1 arm and its helpers deleted); the five raw families carry
skip_deserializing so the hand reader is their only decoder. The four hand
readers refuse a duplicated key; refusals carry a schema-shaped
schemaVersion context and never a received value. README describes only
the raw lane. A same-length str-payload credential forgery is pinned.

describe_decode_error keeps serde's own value-free texts for missing and
duplicate fields (static names from the type), maps unknown-variant and
invalid-type to kind descriptions, and leaves everything else opaque.

Span stages in C#, HLSL and GLSL: SpanPath/SpanStage inputs, float-rounding allowances on curvature and fold, zero-length flat spans, pinned shader guards, exact noise pins, compile-hlsl.ps1 with -WX, struct-aware shader mirror. Soul verdicts cut-stage-functions.s2-s4 and cut-stage-shaders.s1 hold; main's interim changes are cultcache-rs and docs only, disjoint from the verified C#/shader tree.

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.

dxc runs with -WX; a ShaderPath that is not a file throws naming the parameter and entry index,
never the path; the GLSL wrapper builds a struct parameter from its declaration's field zeros.
design.md and README state the struct-argument twin rule, the span twins and the missing shader identity.
No C# change; the compiles run on Starfire after the last commit.

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.

cultmath_span_stage, cultmath_span_fbm and cultmath_span_ridged with SpanPath, SpanStage and
SpanNoise, statement for statement from math.span_stage (no shader identity). They follow the
includes, not cultmath_ridged_grad: the bounds read the SNOISE_* constants the includes define.
The mirror comparison matches every mirror function to the math function of the same name,
public or private, with struct parameters mapped by name and fields; MirrorOnly is gone.
New tests: identity and realistic-span mirror sweeps, a large-octave-step fold test; the
near-origin fold test gains scales 1e-4 and 1e-2; the integral_clamp_linear tests also read the
committed fixture's cases.
The GLSL, the fixture families and the docs follow: CommittedGlslEqualsLowering and
GoldenFixtureMatchesCSharp are red at this commit. It builds.

The spec's negative check greps the script for arm64; the comment matched. Comment
only; script rerun on Starfire (compiles both copies, exit 0; arm64 dxc control throws). Builds.

Stryker survivor on the previous head: direction t1 <= t0 changes a zero-length
sloped span from +0 to -0, which no test observed. Builds; test-only.

glsl: line 307 only (the flat-branch guard). Fixture: one family appended
('zero-length spans and flat infinite clamps'), earlier families byte-identical.
Builds. Together with the previous commit the lowering and fixture tests pass.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The b == 0 branch now guards t1 != t0 like the sloped branch (C# and both HLSL
copies), so an infinite bound times a zero length no longer forms NaN.
Edge-grid mirror test and a counting-clamp shadow test replace the text-order
check; the four pin tests assert equality with their measured expression;
tools/compile-hlsl.ps1 is the one dxc compile verdict for the HLSL copies.
Builds. CultMath.glsl and glsl-parity.json are not yet regenerated, so
CommittedGlslEqualsLowering and GoldenFixtureMatchesCSharp are red at this
commit; the next commit regenerates them.
