Thank you Bruno for the clear explanation.
Let me rephrase your explanation in my own words.
For any point X in the Plenitude corresponding to an observer-moment, a state of
consciousness, or state of a CA, the UD* is just that portion of the Plenitude
1) that point taken as a boundary condition
2)LOGICAL and LOCAL consistency from any point to any point in the transition
("extensions" , "projections") paths.
Hence the concept of "cone" since the number of points reacheable from a given
initial boundary condition is expected to grow. In fact, we may have a double
cone joined at the vertex to represent the logical past and the logical future.
(I do not want to introduce yet the concept of time)
The cone also illustrates the indeterminacy associated with point X. The further
we are from X the greater the indeterminacy. This indeterminacy is of course a
first person perspective from X.
Please also notice my emphasis on the concept of logical and local consistency
on any point along that cone. It may imply that a consciousness my change along
Bruno, so far, I agree with you 100%.
One more point. In my opinion, the concept of first person and third person
perspective is really a special case of a continuum. I will discuss this in a
