Scientific scope

Two2023papers have22/32source-name positions; name variants are retained source-specifically, not identity-resolved. Early multi-level MX designs and later concrete32-element E8M0-scale formats are not silently identical. Quantization/transposition do not commute; vector operations, outputs and master updates remain wider precision. Reported results emulate formats, with distinct direct-cast/PTQ/fine-tuned/training settings; a sample conversion is not the only standards-compliant recipe.
