A clean interactive view of your diagram: numbers are built through multiple paths,
compressed through summation, then traced into residual error requiring balance.

error accumulation
The left region builds values from different internal histories. The middle region compresses
those histories into a simpler sum. The right region shows residual error drifting toward a
balance condition: Err = ± → balance required.
