I would prefer a headlamp over a flashlight - more versatile and just as small. Give some thought to how to power the electronics. My preference would be rechargeable batteries, backed up by a power bank (also abackup flashlight), but there are lots of different stratgies, as well. Just give it some consideration.

A canteen of some sort will be handy - any thing from a recycled Gatorade bottle to the classic nalgene. Fit a cup on the bottom of the canteen and skip the mess kit.

Add a small signal mirror - also good for applying makeup. Also add a whistle so she can have a blast.....

I would favor a good lightweight "real" poncho over the emergency types I have encountered - they are just too flimsy. Same with the heatsheet, although it can comprise a shelter of some sort, for a brief period.

Make sure the paracord is amped up with flammable strands. etc.. Or just get something a bit more compact. IMHO paracord is over rated. Nylon shoelace sets are just as good or better.

What, no paracord bracelet?? Mandatory item for some (not me).

What do you know the specific climate where she will be living? Climate varies tremendously here in SoCal, depending primarily upon distance from the coast and elevation. Be sure she is set up for local conditions and any likely destinations. It is even possible it will rain this winter.
What I would really like to add is an iso-butane fuel canister and burner. You can really cook and boil (purify) water. But you may be better to stick with your current rig.

I would throw in an elastic roll. Does she have any FA training? That is even more important.

Fascinating endeavor - Best Wishes!!

They grow so darn fast, don't they.......
