With advice from GB at Oxygen, figured out how to increase the stack for Jing to do validation, so that's all now working; also figured out how to suppress messages from repeated ant target calls to do that validation, so the output is less cluttered. Confirmed that all validation in the build is now working. Tweaked the Python script so it knows about the taxonomies and personography files.

Then started on meta-diagnostics. I have it now generating a graph showing the progress on all four of the metrics we have right now, by date. I've also started on building a projection object which will tell us whether we're actually going to finish in time or not; lots more to do on that.
