The question I haven't been able to answer is how to determine if a shen particle (an indivisible unit of spirit) has been formed. Once attained, this unit of awareness will survive without a body, unlike the qi structure that served as its matrix.

From what I have been able to see, some of us might seem to have come into this life with one such particle already formed. So called "astral immortality" is a feature some people seem to have, but not everyone does.
Contrary to what NDE stories might have you believe, not everyone is an immortal being having rounds at life for fun. Some are merely loosely-held together qi matrices that manage to reincarnate with semblance of coherence only rarely, and most are aggregates of energy gathered from different and disparate places each time they coalesce before or during their lifetimes.
