The punishment-severity tag has 5 questions and the following wiki excerpt (no wiki):
Questions about weighting the severity of a punitive action against a user.
The disciplinary-actions tag has 3 questions and no wiki.
Some of the questions tagged punishment-severity look like they would be more properly tagged disciplinary-actions, as they aren't specifically about choosing the severity of a punishment.
I think the former is a subset of the latter and doesn't need to separately exist. The concept of "severity", as distinct from disciplinary action in general, is too narrow.
I propose that we merge these into disciplinary-action.
