- The homepage reports 399 of 399 corpus files round-trip byte-identically in CI, including ZIP64 and unknown extensions.
Field notes
The described pipeline preserves unrecognized Office-container parts for write-back, treating unknown content as retained rather than absent. Quire says its paragraph layout uses real font metrics, applies UAX#14 for legal break points, and uses Knuth–Plass to choose among them. The homepage also reports a sub-54 KB gzipped initial WebAssembly payload, with collaboration code deferred to another chunk.
