Some questions about Zstd

Huffman Literals: what is the minimum header bytes? Huffman Fse: what is the minimum weights number should we put (include missing weight)? in spec 4.Stream4_Size = Total_Streams_Size - 6 - Stream1_Size - Stream2_Size - Stream3_Size. Note: if Stream1_Size + Stream2_Size + Stream3_Size > Total_Streams_Size, data is considered corrupted. is the correct note is: total_stream_size < stream1+stream2+stream3 sizes +6+1? ( 1 because minimum stream 4 byte is 1)? Lit stream: is regenerated size should be zero? is compressed size should be zero? Fse sequence - should we configured by mistake offset size 0 ? Block size: is 128k limitation for compressed sizes: it include block header (3 bytes) or not? Thanks, Shuli,
