[support] Saving a node programmatically

For Drupal 7, I'm attempting to create a new node and save it in code. It was working at one time, but now is not and I cannot figure out what it is I did to break it.

The node object appears to be correct both before and after the save.

The node gets created and saved in the database, but only the title is saved with it. None of the data for the body or any of the custom fields gets saved.

I've been over the code a hundred times, tweaking this and that. I've reviewed a.d.o, blog postings, tutorials and various code, and I can't figure out what I've done wrong.

The code is here: http://drupalbin.com/19810

Thank you for any help or pointers anyone can offer me.
