1330362235 CultPhasor rename: README, design note and both changelogs 
cultmath-unity [Unreleased] and cultlib [Unreleased] carry the Breaking entries; no version bump, no tag.

58baccce78 CultMathJson writes CultPhasor as cosine/sine and still reads cos/sin 
Fields takes an optional legacy name per field, matched on read only and mapped to the same index as the current name, so a legacy and a current name in one object are the same property and the duplicate rules decide (refused when AllowDuplicateProperties is false, last wins otherwise). Writing never emits a legacy name. MessagePack bytes are unchanged.

c027d3f884 CultMath.Phacelle.glsl regenerated for cosine/sine 
Written by CULTMATH_WRITE_GLSL=1 on Yggdrasil (sdk:10.0) at d605c70b; sha256 21eef3c38cc609909444c906a1ef965f01b541f2301023a722e64ecc4c846387. glsl-parity.json and device-bounds-lavapipe.txt are untouched by the regeneration.

d605c70bba CultPhasor.cos/.sin become .cosine/.sine in C# and HLSL (GLSL regenerated next) 
SPIRV-Cross renames members matching GLSL builtins, so the source names change. Resolver and JSON writer accessors follow the members; the wire (positional MessagePack, JSON keys) is untouched in this commit. The committed GLSL is stale until its regeneration commit, so CommittedGlslEqualsLowering fails here.

150ea0a060 CultMath shaders: cultmath_power_border, cultmath_lattice_cell_distance and cultmath_weighted_lattice_cells over a fixed-capacity site array 
CULTMATH_MAX_SITES defaults to 128 under #ifndef. The consumer-written ring-loop and border-loop comment recipes are deleted. The C# mirror takes the array as T[]; the span twins live in SiteArrays; the GLSL lowering keeps the capacity macro; gen.py learns the array leaf; the smooth-step family gains its cap-point draw; CULTMATH_WRITE_GLSL refuses non-Linux.
