The assembly sequence was not natural to me. It can be seen that if you break down tonic into four vitae-saltlike pairs the two vitae-air pairs are connected to every other three pairs. The straightforward sequence I tried first was to attach these pairs on that air one by one, and then the arm doing the pivoting every several cycles can't do more work because the atoms to do more work on are not yet bonded. But things are drastically different when you use that connectivity backwards by bonding the rest of three pairs together first and inserting the "central" vitae-air last - suddenly the entire assembly sequence collapses into three pivots, one translation and three more pivots.

An earlier iteration had much more symmetry: two arms doing basically the same things first and second half of assembly. It lost to a sad bonder, and alongside it a more symmetry-friendly track shape and compact glyph layout.
