So the assumption is that headers precede data?

Note that the Zip format usually has two headers per file: one before 
the file data, and one at the very end of the file.

So ideally the archive reader would get the stream first and read the 
end directory if the stream was seekable, then position before the 
first header.

Then as individual pre-file headers were read, their information could 
be merged as appropriate with the end-of-zip (Central Directory) 
information.
