Reduced context-mixing model set (hashed orders 0,1,2,3,4,6 plus a word context and a match model, mixed by one logistic-domain mixer with two chained SSE stages). Ported to be byte-for-byte identical to CompressionWorkbench’s reduced BB_Cmix reference block. NOT the full cmix ensemble (dozens of models, neural/LSTM sub-models, multiple mixer layers) - that reference is impractical to reproduce and this port intentionally matches only the documented reduced subset.
