Decent enough grid - quite difficult - scored 4/10 (moral 5/10 after I didn't hit your terms for the Runner group). I had a feeling that Barlow/Headline/Lappin might be together as a group of words that also form new words when separated into two halves, but that turned out to be Fake News.

This was a sprint grid. I gave myself 5 minutes to make one. It’s pretty flawed.
