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,

(-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.

Key measurement: a query-point weight is common to all candidates and never
changes the winner; site and cell-centre weights differ from each other on
11-15% of pixels; no variant pops in space or time while the window holds
the winner; the window must scale with the weight ratio.

Cut cultmath-tapes cycles-converters (spec r2, attempts h1-h3), held by Soul
s3 (verdict cultmath-tapes:verdict:cut-cycles-converters.s3) under ruling
cycles-kernel-reference-ruled. Main carried only docs since the branch base
b3bd8dd5, so the merged code is the Soul-verified head 53f4c213.

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.

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.

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.

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.

A non-home store (single-file and directory) is read only once the commit holds its own lock, so a foreign record landed at a checked key
while the commit waits is refused; and a directory judge whose lease is held makes TryCommit Contended at once.

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

CacheBackingStore.JudgeChecks (default: the view; single-file and directory stores read under their lock) replaces Land's view-only loop over non-home stores. Foreign takes the version the store read; CultForeignRecord.StoredVersion is get-only and set by the ctor, and every assignment after Foreign is deleted. One commit carries both spec commits 1 and 2 (the edits share hunks); unverified until the final job.
