I have written a small XSLT to strip out the md5 from the XML (though you can use a command line tool like 'sed' if you haven't reflowed the content) as a specific post-processing step.

I found the problem.

It was because I had another version deployed (15.0.0.1), and the
Nexus P2 plugins were resolving 15.0.0 to this version - which of
course has a different MD5.

It was handy you mentioned artifacts.jar since I could look at the
artifacts.xml file and see that the md5 values listed there were the
values that I expected.
Once I found that the plugin jar contents were not real jars (they are
~1KB) and then looking inside them to find a LINK to the 15.0.0.1
version of the jar everything made senses.

Google should be able to help the next fool who stuffs up the version
numbering scheme and comes across this problem from the pain I've had
for the last few days.
