/* References: saffah_codex_6a_agg3 https://duck.ac/submission/129054, accepted lane-cancelling byte kernel and inherited full engine/notices below.
Idea/Purpose: in parity expansion, z is either zero or exactly one power-of-two byte. PSIGNB with value0x80 produces zero for z==0 and0x80 for every nonzero z, including negative0x80 because byte negation wraps. Replace compare-equal plus final mask with that single sign operation, deleting one SIMD instruction per32 output bytes while retaining all source/layout/compute paths. Validate complete byte outputs and official speed.
*/
/* References: saffah_codex_6a_agg3 https://duck.ac/submission/128634, complete accepted byte engine with inherited authors/source/license notices below.
Idea/Purpose: retain the natural two128-bit-lane order of B's byte-unpack results instead of permuting each pair of vectors during256-leaf packing. The resulting column order is exactly the inverse of VPACKUSWB's lane interleave, so the kernel's four final VPERMQ repairs become unnecessary as well. Delete both sets of inverse permutations; parity remains in original logical column order and the final bytes are unchanged. No extra data pass or new arithmetic.
*/
/* References: saffah_codex_6a_agg3 https://duck.ac/submission/128345, accepted fixed-width Gray tables and complete byte engine; all inherited notices retained below.
Idea: Write the 256-row A correction masks in word-major order directly during operand packing. Each word's table query now reads 2KiB of contiguous A masks instead of touching all 8KiB through a 32-byte row stride. Keep the tables, all twelve lookups, result accumulation, low-byte kernel and all other matrix representations unchanged; the generic non-256 layout remains row-major.
Purpose: Reduce the simultaneous correction working set from about32KiB to26KiB without adding a transpose pass or changing any parity bit. */

* Idea: Split the twelve mixed-width correction builders into four fixed six-bit and eight fixed five-bit builders. Preserve table layout and queries, while deleting the per-group width/offset decisions and the conditional sixth-bit tail.

Idea: Select the two Strassen operand signs once at each A/B packer entry.
Nine compile-time sign combinations eliminate all inner tests of the two

parity generation, prefetches and the existing packed representation.
Purpose: remove repeated data-independent decisions from every composed input
packing loop without changing the numerical algorithm or lookup geometry.
