OHM is the Open Human Model, yet any real platform must also model things that are not humans — commerce nouns, instruments, systems. This RFC establishes how OHM may define a non-human entity at all: always in relation to the Human it serves, never as a free-standing abstraction. It is the conscious hinge on which the model broadens to hold commerce vocabulary without losing its human center, and it gives every later commerce concept a rule to be defined against.
