Four Streams Converge

By the last page, the reader can hold four at once because the schema spent the whole book teaching them to.

By the last page, the reader has crossed the continuum enough times that the order is muscle memory; has climbed the depth ladder so often they jump to whichever rung they need; has followed the thread; has accumulated enough setting that the page-one claim has somewhere to stand. Now the original claim returns, and it gets to be proved in the same four dimensions. The close lands because four streams converge at once, which a finite mind can receive only because the schema spent the whole book teaching it to hold four at once.
