about
nx_huffman_kat.nx -- KAT for nx_huffman (canonical Huffman build + decode; the DEFLATE symbol layer).
HONESTY [W] weak point (reach=122; the in-file main self-tests via return-codes but no external node).
Formalizes the canonical-build KAT (RFC-1951 canonical code assignment for lengths [2,1,3,3]) and adds a
DECODE ROUNDTRIP the demo lacked: pack canonical codes MSB-first, decode them back to the symbols.
