blocked on two things:

1. both go.mod files replace cosmos/cosmos-sdk with github.com/mmsqe/cosmos-sdk (personal fork). needs to wait for cosmos/cosmos-sdk#26208 to merge upstream before this can land.

2. branch is 72 commits behind main -- ci passed against stale state, needs a rebase before this can be meaningfully reviewed.
