I use #7937 to detect when there would be a problem if "current" agoric-sdk were upgraded to depend on "current" endo. My latest CI run just now https://github.com/Agoric/agoric-sdk/actions/runs/6514769656/job/17696503348?pr=7937 indicates four failures under CI. Two of these are lint failures and may have a common underlying cause. The other two are dynamic failures I have no diagnosis for, but they seem like distinct problems.
