about

nx_sevenz.nx -- THE 7z ARCHIVE COMMAND (/compare/modding MD29 sz_walk, 2026-09-06). A thin caller of nx_sevenz_lib so the command line and the bundle walker read a 7z through ONE container reader and ONE decoder (nx_lzma_lib), and every member's bytes are checked against the archive's OWN CRC-32 digest -- the container is the oracle for the decoder. usage: nx_sevenz list <archive.7z> one MEMBER row per non-directory file, then one SEVENZ summary row nx_sevenz extract <archive.7z> <idx> <out_path> write member idx (its decode must be OK or STORED) exits: 0 every data member decoded and CRC-verified | 2 usage | 3 REFUSED (unreadable, not a 7z, truncated, a CRC or the header refused -- the reason is on the line) | 4 walked, but a member failed or its coder is unsupported (named per row) license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0
