A boson is an entangled shell of propagating oscillators.
Propagation is fundamentally not vector-like, but is scalar (or radial in space).
A boson exists as a degenerate entity, without unique location, and disconnected from reality, until it can form a fermion.
Bosons and fermions are made of the same stuff, but their physical manifestation depends on the uniqueness or commonality of their attributes.
Fermion state is simply a snapshot of the states of the contributing oscillators, with two of the waves privileged in a coupled state.
