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.

iv_frustum_ball widened by its derived float32 bound, envelope-then-noise
fields, the analytic constant-density body, one shipped void (Rh 198, S 50),
LOD agreement against a converged march, and the wells contract as ruled
(cultmath-tapes:ruling:wells-overhead-plus-floor). Verdict
cut-interval-ops.s3 holds; one Low finding (LodStep footprint branch unpinned)
is recorded for the next interval cut.

publish-packages.yml runs the suite in both jobs, after .NET setup on a full-depth
checkout and before any check or publish step; the three Unity release scripts run
it before the checker. A test reads each file and fails when the step is removed,
moved, or made non-fatal. The Caching Unity pin now needs a prefix declared once
whose exact tags hold the package's own manifest at the tag's version. No NUL byte
in the checker is a test. The policy records that releases run from a full clone.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The checker reads each package's tag prefix, changelog and assemblies directory
from scripts/release-packages.mjs and derives the release record from git tags.
A first release is the absence of any older tag in a checkout that holds other
tags; a malformed same-prefix tag, a checkout without tags and an unreadable
repository refuse. The measured set is every managed assembly (CLI header in
the PE bytes) tracked at the previous tag at any depth; an unbuilt one is a
break, a built assembly with no namesake is an addition.
Deleted with their branches, refusals and tests: --first-release, --api-new,
--tag-prefix, --changelog, --api-baseline-path and the workflow first-release
decision line. Any unknown option is now a usage error.

math.Interval.cs and shaders/CultMath.Interval.hlsl (included from CultMath.hlsl after Phacelle;
both tracked copies) add iv_point, iv_add, iv_sub, iv_neg, iv_mul, iv_scale, iv_abs, iv_min,
iv_max, iv_sqr, iv_sqrt, iv_exp, iv_clamp, iv_saturate, iv_smoothstep, iv_lerp, iv_snoise_ball
and iv_fbm_ball, and SNOISE_LIPSCHITZ = 10.099261 (1.10 x the refined max |snoise_grad| that
NoiseBoundTests.MeasureLipschitz prints). iv_exp and iv_smoothstep widen by one ulp through
asfloat(uint), added beside asuint as the HLSL intrinsic. The mirror test now compares 52
functions; the Unity package and the NuGet content files carry the new include.

The check moves from before the build to once the assemblies under judgement
exist, and receives every shipped GameCult.* DLL (cultlib) or the fresh
CultMath.dll with the baseline path of the previous tag's tracked plugins.
The early calls are deleted; each script keeps exactly one.

MPL-2.0 is file-level and the Phacelle port sat inside MIT files. phacelle and
CultPhasor now live in math.Phacelle.cs and CultPhasor.cs, and cultmath_phacelle
in CultMath.Phacelle.hlsl (included by CultMath.hlsl, both tracked copies), each
with the MPL header and Johansen / Luke Mitchell attribution. math stays one
partial class, so math.phacelle is called exactly as before. The GameCult.Math
package declares MIT AND MPL-2.0 and packs THIRD-PARTY-NOTICES.md and the new
include; the Unity LICENSE.md points at CultLib; build-unity-package.ps1
requires the new include.
The random sweeps never met a cell whose box bound sits just under the 2.25 cut
while its weight is still nonzero, so cuts of 2.245, 2.24 and 2.2 survived.
Six hard-coded points (found by an offline search) sit next to such cells; the
C# pruned-vs-unpruned test and the HLSL mirror test both use them, with a
witness check that re-derives the property from the hash.
Docs: the prune keeps about 45 of 64 cells (14 is the nonzero-weight count),
the support radius is 1.49998 (d^2 = 2.24995), normalization's range and
saturation, W = 0 only for adversarial hashes, and the support-edge gradient
seam size.

1.0.60 removed public API (CultInspectorAssetPath) under a patch bump; its
own changelog says "Breaking" and the version number lied. Operator ruling:
semver is policy, strictly, for every published package family.
docs/semver-policy.md states what counts as breaking per surface (managed
API, Unity inspector attributes, CultCache wire format/store compatibility,
CultNet protocol, native bridge exports), the 0.y.z pre-1.0 convention, tag
naming, and required changelog shape. Records the 1.0.60 scar as history;
does not renumber it.
scripts/check-changelog-semver.mjs is the mechanical check: refuses a
changelog "### Breaking" section under too small a bump, and refuses a
version that skips, reverses, or repeats the previous published tag. Skips
re-litigating a version that is already tagged (rebuilding immutable
history is not a release action). Wired into publish-packages.yml for the
four npm/PyPI packages, and into build-unity-package.ps1 (cultlib),
packages/cultmath/scripts/build-unity-package.ps1 (cultmath), and a new
scripts/verify-caching-unity-release.ps1 (caching.unity has no build script
of its own to hook into).
18 node:test cases cover the required table (breaking+major/minor/patch,
non-breaking, 0.y.z, skip, downgrade) plus CLI-level git-tag resolution.
Hand-mutated each rule (bump classification, pre-1.0 lane requirement,
breaking-heading detection, breaking early-return, already-published skip)
and confirmed each kill, then restored byte-exact. No mutation harness is
committed; CultLib has none today.

The previous commit's DLL and pdb came from an incremental build that did
not recompile after the Source Link switch, so the pdb still carried the
commit URL. The script now builds with --no-incremental, so a stale obj
directory cannot decide what the byte check compares.

The tracked DLL is committed with its source, so a build that embeds the
commit can never match it. Two places named the commit: the informational
version (0.2.0+<sha>) and Source Link's commit URL in the pdb, whose content
id the DLL also carries. The csproj drops the revision from the version, and
the Unity build turns Source Link off; NuGet packs keep it.

build-unity-package.ps1 read the bridge's file names to decide whether it
re-declared core CultMath sources. It now parses declarations: core type
names come from src/CultMath (comments stripped), and every bridge source may
declare types only in CultMath.UnityBridge and never a core type name.
Probed by injecting "struct float3" into UnityConversions.cs: the script
throws.
Strips the UTF-8 BOMs this branch added to both Unity package.json files.

- Bump GameCult.Math and org.gamecult.cultmath to 0.2.0; the CultCache
Unity tools package now depends on cultmath 0.2.0.
- Rebuild the tracked netstandard2.1 CultMath.dll/pdb with the builder's
deterministic command; build-unity-package.ps1 verifies it byte-for-byte.
- Add Runtime/UnityBridge (CultMath.UnityBridge asmdef) with ToCultMath /
ToUnity / ToColor extension methods for Vector2/3/4, Vector2Int/3Int,
Quaternion and Color. C# only admits conversion operators on the source
or target type, and the core DLL stays engine-free.
- The builder admits exactly that one bridge assembly: it must reference
UnityEngine and CultMath.dll, and no core source may be compiled in the
package.
- Sync the Unity copy of CultMath.hlsl and the third-party notice.
