  We consider a system of interacting Fisher-Wright diffusions with seed-bank.
Individuals carry type one of two types, live in colonies, and are subject to
resampling and migration as long as they are active. Each colony has a
structured seed-bank into which individuals can retreat to become dormant,
suspending their resampling and migration until they become active again. As
geographic space labelling the colonies we consider a countable Abelian group
endowed with the discrete topology. In earlier work we showed that the system
has a one-parameter family of equilibria controlled by the relative density of
the two types. Moreover, these equilibria exhibit a dichotomy of coexistence (=
locally multi-type equilibrium) versus clustering (= locally mono-type
equilibrium). We identified the parameter regimes for which these two phases
occur, and found that these regimes are different when the mean wake-up time of
a dormant individual is finite or infinite.
  The goal of the present paper is to establish the finite-systems scheme,
i.e., identify how a finite truncation of the system (both in the geographic
space and in the seed-bank) behaves as both the time and the truncation level
tend to infinity, properly tuned together. If the wake-up time has finite mean,
then there is a single universality class for the scaling limit. On the other
hand, if the wake-up time has infinite mean, then there are two universality
classes depending on how fast the truncation level of the seed-bank grows
compared to the truncation level of the geographic space.
