Comments: 42 pages (16-page main text, references, and supplementary material), 14 figures, 35 tables. The incremental tokenization path and the fast encoder are open source in toktier at https://github.com/asu-idi/toktier. The chunk-parallel path, the CPU pool scheduler, and the SGLang adapter will be released in the same repository
