4 Channels, 5 Tracks. Using the pigeonhole principle, at least one channel has 2 tracks. The 5th Track is on the same channel as the 2nd Track. Therefore, the Intersection point for the handoff is on the bonder. Mors is disposed of because it is not used in the product. The mors exists on the same island as the disposal for this purpose of being disposed of by the disposal.
Not salt become salt when it goes over the calcification glyph.
Due to cost lacking the duplication glyph, not salts that become salt when it should be not salt becomes salt and cannot be not salt. This not supposed to be salt salt can only not be salt if the calcification is not placed to route the not salt the not salt into salt.
There are essentially 16 vectors of movement available (4 each, but -2 for the channels with a reagent). The possible movements can be easily enumerated through tracking which channel each atom currently occupies, and how each vector changes the channel.
The construction is oddly convenient with the reagent pulls. Some may even call it a coincidence. I’d even hazard a guess and say the playtesters found this procedure and worked and volkswagen'd the atoms to make 105 possible.
Rebix was a great help in grinding this down to where the tertiaries lie. Several movements do multiple things, or avoid doing multiple things. However, I do feel there is some inefficiency that still exists here that someone may have been able to find.
