Their results carry the curvature constant; the platform-bound families stay as generated on Windows.

CultMath.glsl is GlslLowering's output (CULTMATH_WRITE_GLSL=1, run on Yggdrasil); the fixture keeps every
earlier case byte for byte (the platform-bound families stay as generated on Windows) and appends the three
new families, which depend on no libm.

MeasureThird on the tied kernel: refined 488.1047, x 1.10 = 536.9152, witness (-168.3755, -3.8205261,
-109.16948). MeasureHessian with the analytic Hessian: refined 50.58377, x 1.10 = 55.642143, witness
(-13.7920685, -9.672134, 61.563934); the central-difference value 56.050385 carried the quotient's
roundoff. README bullet for the span primitives. CultMath.glsl and the fixture are not yet regenerated.

math.Span.cs adds the analytic Hessian of snoise(float3) on snoise_grad's tied kernel and the closed-form
integral of a clamped linear ramp; HLSL twins and the Unity copies follow, HessianNorm now reads the
library Hessian, the GLSL lowering gains float3x3 to mat3, and MeasureThird/ThirdConstantPinsSampled and
SpanPrimitiveTests land. SNOISE_THIRD is a placeholder (1) until MeasureThird runs; CultMath.glsl and the
fixture are not yet regenerated. Does not pass its tests.

infinite.json holds 47 cases of infinite operands for cycles_power, cycles_modulo and Map Range Smooth Step, made inside Blender's kernel; only that family was regenerated. CultMath.Cycles.glsl changed by the generator alone (CULTMATH_WRITE_GLSL=1); glsl-parity.json and CultMath.glsl are byte-identical. This commit builds and its tests are expected green.

cycles_power read b - 2 floor(0.5 b) != 0 as odd, which is NaN for b = +-inf, so a negative base got a negative result where Cycles' powf(a, +-inf) is never negative. Odd now means the remainder is exactly 1 (C#, HLSL, Unity copy). oracle.py gains the infinite family (operands made in-kernel as +-exp(100), results read through comparisons with 0) for power, modulo and Map Range Smooth Step; the infinite.json fixture and the regenerated GLSL follow in the next commit. This commit builds; InfiniteOperandsFollowBlender and CommittedGlslEqualsLowering fail until it lands.

Main's codec-document tests and the RUDP document-handle test read a record
stored under codec_note, plain_note or a foreign id through a handle for an
alias schema, and one store test picked among foreign-id records by whether
they parse. retire-schema-alias makes that read refuse; C2a's own tests
(a handle reads only records under an id its definition declares) pin the
rule. The codec reads and syncs under the definition's own id stay.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Main's two payload-depth tests staged a record with no catalog entry and
asserted that the inspector and the single-file store infer its schema from
the payload's first element. C2a refuses a record whose schema id the catalog
lacks (merge-r1-precedence, exact binding), so the guess door is gone. The
inspector test keeps the bound check with a catalog entry that names the
schema; the store inference test goes with the door.

Main's documentFromPeerSnapshot takes a definition only, so the string-handle
read (first record at the key) that C2a held for Eve Electron cannot be
expressed; the assertion and requestCultNetRawSnapshotDocument's
firstRecordAtKey option went with it.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
C2a's writer, catalog and soft-push tests handed raw Uint8Array payloads to
the store. Main made the envelope payload an opaque DocumentPayload, so they
wrap with documentPayloadFromBytes and read back with documentPayloadBytes.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Sixteen conflicted files resolved by the spec's rule: main owns payload
ownership, bounds and the Clock seam; C2a owns persistence semantics and exact
binding. MintStoredAt is internal static (previous, now); the cache and the
store pass their cache's Clock. Package versions are main's. The cultmesh-ts
payload-parse acceptance and its test are deleted under retire-schema-alias;
peer snapshot reads take the schema's own id, else an id the definition lists
as compatible. The held firstRecordAtKey fallback is removed: main's handles
take definitions only, so nothing could reach it.

Fixtures are the oracle's output (SSE4.2 kernel, Blender 5.2.2 Linux), two runs cmp-identical; CultMath.glsl line 1 (the
Cycles function list in the generated header) carries the three new names.

Fixtures and the regenerated GLSL follow in the next commit, so the tests that read the new rows
(InverseTrigonometry..., OperandStreams...) are red at this commit.

The z channel's boundary mutant survived because 0/0 reads as 0 after the clamp. mix.json follows. Builds.

Byte-identical regeneration for the other five families. CyclesOracleTests and the mirror tests pass (29 of 29).
Builds.

Stryker's survivors in math.Cycles.cs that were not equivalent: Burn's divisor <= 0 boundary, Logarithm's
a <= 0 guard, and rgb_to_hsv's h < 0 wrap. mix.json is regenerated in a later commit, so
FamilyMatchesBlender is unchanged here and the new Burn rows are absent. Builds.

The oracle showed Cycles treats a huge exponent as integral for a negative base, so the speculative
b >= 2^31 rule is gone. CultMath.Cycles.glsl is stale at this commit (the HLSL changed), so
CommittedGlslEqualsLowering fails here; the regenerated file follows. Builds.

The film zeroes an infinite result, which had hidden both the power quirk and Compare's epsilon floor
from the fixtures (two hand mutants of the HLSL survived). The fixtures are regenerated in a later commit.
Builds.

A mutant of CultMath.Cycles.hlsl that changes a Cycles result the fixtures reach now fails a test on its own;
before, only the random-input mirror comparison reached the HLSL. Builds.

Written by tools/cycles-oracle/oracle.py and GlslLowering on Yggdrasil; the tool's second run was
byte-identical. CultMath.Tests passes 379 of 379 at this commit's tree. Builds.

The oracle's first fixtures showed Cycles' AVX2 kernel fuses multiply-adds and its film zeroes
non-finite results; the tool now exits 4 off the SSE4.2 kernel (CYCLES_CPU_NO_AVX2=1) and the
test skips cases Cycles cannot report. The Unity copy of CultMath.hlsl carries the new include.
Builds. Fixtures and CultMath.Cycles.glsl are still to come.

Builds. The oracle fixtures and CultMath.Cycles.glsl are still to come, so the oracle and golden tests fail here.

oracle.py bakes each Cycles node under Blender 5.2.2 LTS (build d13f752e3b9c, refusing any other)
into float images; CyclesOracleTests holds math.cycles_* to the fixtures it writes. No fixtures
exist at this commit, so the tests fail here; builds.

Ports of Blender v5.2.2's intern/cycles kernel functions, one function per node
operation, with the HLSL mirror, the Unity copy, the lowering table entry for a
separate Apache-2.0 GLSL file, the golden-fixture families, the package licence
expressions and the notices section.
Builds. Does not pass yet: CultMath.Cycles.glsl and the regenerated golden
fixture arrive in a later commit, so CommittedGlslEqualsLowering and
GoldenFixtureMatchesCSharp fail at this commit.

The wide-count test announced map32 as 32770 pairs, which fits in 16 bits, so a
count read as its low 16 bits survived. map32 now announces 65537 pairs and
array32 65540 children; both low halves close the container early.
Builds: yes.
