This illustration is not a code. The architecture of the government is based on the phocomelia genetic disorder. Phocomelia is explained in About The Conscience
Like B and b denoted the dominant and recessive traits for eye color, the letters in this picture denote the dominant and recessive dispositions for conscience. This is a particular build for a person learning about phocomelia.
When Thomas Jefferson designed this he believed that the people with mal formed hands were the basis for primary and secondary qualities and that they are responsible for Democracy.
The primary quality that he was after was the recessive-recessive disposition for conscience in relation to a person with phocomelia. The secondary qualities were everyone else affected by that primary quality. It is also possible for the primary quality person to have a dominant-recessive disposition for conscience; but, that would be an entirely different governmental build. Thomas Jefferson had a serious belief that the primary and secondary qualities were based on people and how they feel things.
