Looking good! Not done a fully exhaustive review, these are just the first things I spotted.

Seems like we as a codebase need to decide where action permissions checks go - the action function or the feature? My preference is for the former as it's easier to tell what permission an action needs.

Otherwise looking good, mainly just error handling.

Having the permissions checks in the features makes sure that checks aren't forgotten when implementing those features in the future, some features are also passed directly from server components without an action wrapper and so the checks are required in the feature.
