about

nx_jpeg_dht_test.nx -- KAT for DHT parser + Huffman decode. Test cases: A. Synthetic 2-symbol table: BITS={1,1,0...}, HUFFVAL={0x05, 0x06}. Symbol 0x05 -> code "0" (1 bit); symbol 0x06 -> code "10" (2 bits). B. Decode test: bitstream "0 10 0 0" packed MSB-first = 0x40, should yield symbols [0x05, 0x06, 0x05, 0x05]. C. Dual-table payload (luma DC + luma AC stacked). D. Malformed -- BITS sum >256 truncation. expect_exit: 0 license_tier: ORIGINAL
