Lineup
The two circles of equal rank, the six locked digit marks, the machine. The test: solid disk and open ring must read as one pair without touching the digit grammar, and ⊙ must read as senior to everything on its left.
The steps
⊙ generates the whole system. Keep the shell: IndexRoot's ring. Keep the core: Index.'s dot. Turn the axis side-on: the bar. Cut the atoms: the digit bots. One fundamental, three atoms, eight marks.
