Isn't it what it says? The box says M2 = M1,0 + M1,1

It is a possibility to embed, say, a JSON data into HTML directly, instead of using a link. This possibility did come up on the EPUB discussion; there are pros and cons of course. I believe that only thing we are saying that, at least at this moment, there is no reason why PWP would disallow this approach. Hence the inclusion in the diagram.

Why? To take the example you brought up a while ago, the unpacked version may use the <link> element to some local manifest file in the package (and the same manifest file would then be present in the packed state) but the publisher may want to put things on a server without changing the content of the PWP itself (whether it is in a packed or unpacked state). So no, M1,1 and M3 may very well be different. I guess the typical situation may be, in this situation, that the Lp and Lu values would actually be conveyed to the PWP Client processor via M3 and not via M1,1.

This is what we agreed upon...

And if I am correct that M1,1 from the link in head – what would happen if you ALSO have a link HTTP header?   Do you really get two copies of M3??   That gets confusing in the diagram.

See above. I do not think it is confusing if things are different.
