My idea is, you need to buy everything from all of the shops in the entire game in order to complete the run. Timing would start upon gaining control of link like in any%, and end upon clicking buy on the final item in the last shop.

Edit: I'm going to include any NPC's that sell stuff (i.e. Beedle), just so I don't forget anything

1. Think of a good way for both runners and verifiers to verify that you didn't miss any
2. Run it
3. Think of a shorter name

For verification, I think that the runner and verifier(s) could make a list of all of the shops and NPC's that there are in-game and cross items off of said list as the runner visits them.

I agree. It would be kind of like all dog treasures. The name could be shops%

Right. Shop%

we should start a google spreadsheet or something for all of the shops, maybe ordering them in region, and then begin routing, i would be happy to assist since i have nothing else to do in my spare time!

i don't have twitter, would discord work for you?
