[aaxelb]

a couple suggestions to avoid unnecessary queries and reader confusion, but overall seems good

[aaxelb]

could avoid the two exists queries and simplify a bit by using values_list:

dates = filter(bool, [
  node_logs.values_list('created', flat=True).first(),
  preprint_logs.values_list('created', flat=True).first(),
])

[aaxelb]

this is pretty convoluted, setting a non-existent attr on the user instance for use elsewhere

could make it more explicit by adding a month_last_active field to _InstiUserSetup (with init=False because it's computed in __post_init__, like user)

month_last_active: YearMonth | None = dataclasses.field(init=False)

then set self.month_last_active here and access setup.month_last_active in the test assertion

[aaxelb]

oh, small point of "names shouldn't lie" (not to mention that type annotations shouldn't lie):

if leaving names (and annotations) as they are, should cast this to YearMonth here instead of in the test (which would save you the if/else)

or if leaving logic as it is, should rename the field something like date_last_active and change its type annotation to datetime.date | None

either way, as long as words and logic agree
