  Using Promise Theory as a calculus, I review how to define agency in a
scalable way, for the purpose of understanding semantic spacetimes. By
following simple scaling rules, replacing individual agents with `super-agents'
(sub-spaces), it is shown how agency can be scaled both dynamically and
semantically.
  The notion of occupancy and tenancy, or how space is used and filled in
different ways, is also defined, showing how spacetime can be shared between
independent parties, both by remote association and local encapsulation. I
describe how to build up dynamic and semantic continuity, by joining discrete
individual atoms and molecules of space into quasi-continuous lattices.
