Full #Maneage controls + fixed seed rng's. We still have intramachine + (higher) intermachine randomness. Statistical upper limits to results OK. But still untraced sources of randomness.
Any clues for remaining randomness [2]?

Check this starting with a floppy-disk sized source snapshot [1].
#Reproducibility is via the #Maneage template of shell+make files.
