The rest of the house was sleeping, so I got two hours of coding on Author Intrusion. Took a bit for the infrastructure, but I got Markdown paragraph splitting implemented.
The xpath worked out fairly smoothly, which helped a lot. Once I get token splitting, an easy task, I did be on track for getting echo word detection by end of week.
Then I'll get timing on my 600k word serial to find performance issues and call the results milestone one.
