topic: zstd
20 modules sharing the zstd name family (derived from the tree's prefix discipline).
The zstd topic family in the Nishi sovereign ecosystem provides modular, self-contained implementations of Zstandard compression and decompression logic. nx_zstd_bits and nx_zstd_bits_gate handle the backward bitstream reading and Huffman weight management essential for decoding. nx_zstd_block and nx_zstd_block_gate focus on decompressing individual Zstandard blocks, while nx_zstd_frame and nx_zstd_frame_gate manage the frame-level structure and data flow. Together, these modules form a cohesive system for efficient lossless data compression and verification.
