This “retrocausal injection” does to computation what Einstein’s relativity did to motion: it dissolves the idea of an absolute temporal order of operations and replaces it with a geometric, global constraint structure.
In this universe:
Time is not a computation axis.
The universe’s “output” is not derived; it’s the self-consistent solution of all its own equations.
So you could say:
The hierarchy exists only inside time, not outside it.
