Detailed Description

Byte permutations across whole vectors and circular qword bit windows. Runtime targets require AVX512F, AVX512BW and AVX512VBMI; 128/256-bit forms also require AVX512VL. Admit CPU features and OS ZMM state before entry. Single-table indices use log2(lanes) bits; two-table indices use one more. VPERMI2B merges inactive index lanes; VPERMT2B merges inactive first-table lanes. Multishift selects eight wrapping bits from the corresponding qword. Constant evaluation uses exact integer semantics. Weaker tags are accepted only at compile time and still require complete SIMD storage.
