Results

{
  "nested_selection_factor": "300/299",
  "whole_duration_P_then_J": "7000/6877",
  "general_law": "A_g(A_f(k))=A_(gf)(k)"
}

Finding

Nested selection gives J; applying P and J successively gives their product7000/6877. These are different operations despite sharing the same factor names.

Reassessment

Prove when a component conversion can pass through coarsening without losing its meaning.
