Coherence Map

Each domain below is laid out in prerequisite layers. The first row needs nothing before it. Every later row builds on the rows above. "Before" and "After" are the outcome's immediate neighbors; an outcome's own page lists prerequisites from other domains too. Stubs appear where they sit in the graph, drawn with a dashed border; they are the concepts waiting to be written.
