Clues with with (+) are entered clockwise; clues with (-) are entered widdershins. When the diagram is filled, one cell of each ring has a letter (or letters) corresponding to the compass direction of the cell:

These directions form a single path through the diagram, visiting each ring exactly once, with the final ring exiting the diagram. As clued by the flavor text, the cell directly across from the double-cell in each ring is important. Reading these in order of the path spells the clue phrase SOLUTION FLOW AND THEN CHARTS, leading to the solution of FLOW CHARTS.
