Transformed once per row: the values are distributed, and each token is also changed, or rotates through a position, or a cell names a transformation that is applied elsewhere in the grid. This is the APM’s own family, matrix transformation, and the bank’s transformed distributions, and it is where correspondence finding, which element belongs to which rule, does the work.
What you see: three things reappearing, but not quite the same each time. What you do: name the underlying value, then the change applied to it.
