Total time spent on this metric was around 30 hours total.
Arm grabs the fire by the fire and makes fire bonds with the fire. These fire bonds are necessary for completing the fire product that contains fire bonds.
Fire becomes salt when it goes over the calcification glyph.
Due to the puzzle lacking the duplication glyph, fire that becomes salt when it should be fire becomes salt and cannot be fire. This salt that was fire but is now salt is waste. We do not want waste, therefore the calcification glyph is put in a position where it will not make fire into salt when it should be fire.
The reagent location is suppressed during the monomer slide by the lone salt because otherwise the reagent would spawn and block the monomer slide. The lone salt is salt and not lone fire because lone fire would make fire bonds with the monomer. This is avoided by using lone salt instead of lone fire because lone salt cannot make fire bonds with the monomer.
The capacity of the layout can support two arms because the sliding monomer requires two hexes of sliding and one additional hex for salt storage. An additional arm is another hex however, and 3 does not equal 4 however, but however the other arm can move the salt in the gaps of the infinite so it is not in fact 4 but 3, and 3 does equal 3.
Final monomer is wrong because the wrong monomer is used as the final slide. The product does not check for wrongness in the area the wrong monomer is wrong, therefore it can be argued that the right monomer was used to save 2 cycles.
