Libby	bbee623e29	CultMath: Phacelle rows are order-independent (forward, backward, shuffled) ... Pins that height rows built from math.phacelle (the C# mirror of cultmath_phacelle) are bit-identical whatever order the rows are generated in, for a ring-buffer terrain. Golden fixture untouched.

Eureka	883271f62c	CultMath: regenerate lavapipe device bounds at 85ce65fa ... Exact-case counts move: cycles_arcsine 154 -> 155 and cycles_arctan2 6 -> 7 on both routes; worst u1 and result hashes unchanged. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>	2026-11-04 20:26:13 +00:00
Libby	5d8e032d7f	cultmath: glsl-parity header names the recording image and lavapipe/Mesa; asin/acos/atan2 oracle tolerance capped at 1 ulp ... The glsl-parity.json header gains recorded_on (generator writes it; goldens untouched). CyclesOracleTests allows cycles_arcsine, cycles_arccosine and cycles_arctan2 (glsl-parity families 95-97) 1 ulp from Blender, with the measured cases named; a test pins the cap at 1 ulp, the three names, and that a 2 ulp miss still fails.

Libby	b57501b33e	cultmath: phacelle-lipschitz prints usage and exits 2 on missing or malformed arguments ... Without arguments the tool threw IndexOutOfRange; a malformed number threw FormatException. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>	2026-11-02 18:33:18 +00:00
Eureka	3b58b24a68	cultmath: re-record device-bounds-lavapipe.txt for cultmath_fbm ... Recorded on Yggdrasil under llvmpipe (LLVM 20.1.2) with packages/cultmath/tools/device/run-lavapipe.sh, WRITE_BOUNDS=1, at 990521b3. Adds the lavapipe-glsl and lavapipe-hlsl rows for cultmath_fbm only. The cycles_arcsine/arctan2 rows are left as committed (pre-existing asin/atan oracle failures at base 94f20eee are out of scope).

libby	990521b3f1	cultmath: measure the Lipschitz bound of phacelle, with its tool and a pinning test ... max singular value of the (cosine, sine) Jacobian <= max(10, 1.25 |side|) / (1 - normalization) for normalization in [0, 0.9], |side| in [0.25, 25]; method and tightness in design.md.

Meta Vens	ab86876362	build-glsl.sh: delete the [128] shape arm; the shape check runs on a library array of length 128 through the real script ... Selection is by name, so a non-site 128 array is legitimate output. The shape check is a function and the array-128 variant passes it.

Meta Vens	7416e8a775	glsl build: the capacity constant carries CultMath's own SpecId, so a consumer's SPIRV_CROSS_CONSTANT_ID_0 cannot clash ... SPIRV-Cross names the macro from the SpecId and offers no option to rename it, so the SpecId is CultMath's own ('CMS1'); partition.py reads it from spvedit.py. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-17 23:00:04 +02:00
Meta Vens	ae838b60fd	glsl build: the capacity edit names the site arrays by a sentinel length, with tests for the tool refusals ... wrappers.py compiles the library with CULTMATH_MAX_SITES defined as a sentinel no shader file spells, so the three site arrays get an array length id of their own and spvedit.py converts exactly that constant to the overridable specialization constant (default from the HLSL guard). A library array of literal length 128 keeps its own id and stays a plain constant. build-glsl.sh gains the pipeline function and scratch variants: a macro outside a declarator, a folded expression reaching the capacity id, and a non-site float4 x[128] parameter that a consumer's override must not resize. The [128] shape arm goes: a non-site 128 array is legitimate output. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-17 22:59:55 +02:00
