Can somebody please tell me if I have the current status of our
knowledge of antimatter and gravity correct?

Passive:   Antimatter has been observed to "fall" towards regular
matter (e.g. positrons fall towards the earth) (reference please?)

Active:   No observations exist for matter or antimatter to "fall"
towards antimatter

Something to keep in mind - What one calls "matter" and "antimatter"
is merely a convention. Historically, protons, electrons and neutrons
were discovered before their corresponding anti-particles. For this
reason the anti-particle for the proton "anti-proton". Same for the
neutron. When a new particle is discovered it is typically referred to
with a name and its anti-particle is called the "anti-(name)". There
is no real sense other than convention to say what is matter and what
is anti-matter?.
