plans with only a handheld, right?

Why wouldn't you say "handheld on board" if you didn't actually have a

using the handheld GPS for direct routing (otherwise why would there
be a comment in the flight plan and the request for direct enroute?)

Because you get the vector and then use your handheld. That is legal.
