Capstone - Order Fulfillment, Built Twice

1. How This Capstone Works

Most capstones in this course build one system. This one builds the same system twice: order fulfillment with two-phase commit, then again as a saga: and then injects the same three failures into each build and compares the damage. Because that is what this module actually teaches: not "which pattern is better," but whose failure modes your business can live with.
