The Iterative Loop
The cycle of describe, generate, evaluate, refine that characterizes AI-augmented building — read through Tufte's framework as a small-multiples workflow operating in the temporal dimension.
The iterative loop is the characteristic rhythm of AI-augmented software development: the builder describes an intention, the system generates an implementation, the builder evaluates the implementation against her intention, and the system adjusts in response to the evaluation. Each cycle is a round of controlled variation — the next version differs from the previous in a specified dimension while everything else is held constant. The sequence of versions forms a temporal series of small multiples, and the builder's analytical work consists of detecting meaningful variation across this series. Tufte's principle that controlled comparison is the most powerful analytical instrument available to human perception applies with precision: the loop's productivity derives from the quality of the comparisons it enables, not merely from the speed at which iterations are produced.

The loop's analytical power is fundamentally different from the mode of evaluation the traditional spec-based process permits. In the traditional process, the builder writes a spec, waits weeks for implementation, and
