Les Houches 2021: Physics at TeV Colliders: Report on the Standard Model Precision Wishlist

Les Houches activities in 2021 were truncated due to the lack of an in-person component. However, given the rapid progress in the field, and the restart of the LHC, we wanted to continue the bi-yearly tradition of updating the standard model precision wishlist. If nothing else, this will keep us from having even more work to do at Les Houches 2023.
