" summary

Argument that small, repeated choices become the system's physics: execution architecture (threading, event vs time‑triggered) and naming or API choices shape cost and changeability. Concrete examples include Google Maps zoom hiding driving direction, the left-pad incident breaking many sites, Schiaparelli's IMU assumption causing a crash, and the Java cloneable misspelling that propagated. Demonstrations include sorting algorithm experiments (permutation, bogo, sleep sort) and a tiny JS test harness that reveals real npm packages fail. Claim: measure by implementation and runtime observation; configuration is code.
