HLSL is now CultMath's semantic authority where it defines one. - float2/3/4, int2, double2/3, bool2 and quaternion are plain structs with public mutable fields instead of record structs. Indexers and swizzles (float2.yx; float3 xy xz yx yz zy xyz xzy yzx zyx; float4 xy xyz xyw yzx) have setters. - ==, !=, <, >, <=, >= are component-wise and return bool2/3/4. Equals and GetHashCode stay value-based so vectors remain dictionary keys. quaternion is not an HLSL type and keeps a bool ==. - Scalar/vector arithmetic and comparisons get explicit overloads on both sides instead of leaning on implicit splat. - New types: bool3, bool4, int3, int4, float2x2, float3x3 (row-major like HLSL, _mRC fields, Rotate / RotateX/Y/Z / Euler with math.RotationOrder). - New intrinsics: mul (matrix-vector both sides, matrix-matrix), any, all, select (HLSL argument order), log, vector pow/sqrt/sin/cos/acos/atan2, double min/max, int3/int4/bool3/bool4/float2x2/float3x3 constructor functions. - simplex_noise is renamed snoise and gains the Ashima 3D variant; the HLSL mirror follows as cultmath_snoise(float2/float3). - Random gains NextFloat3() and NextFloat3(float3 max) on the same draw order. Tests pin snoise(float3), float3x3.Euler and float2x2.Rotate to Unity.Mathematics reference values, and an HLSL-shaped source block compiles under using static CultMath.math.
