Part III
Compare#
Compare is about producing implementation C through a declared agent fleet and then explaining what all three systems reveal. The Compare project brief defines the fleet workflow, its trace-based debugging view, and the final three-way comparison. Students now use shared pressures and evidence to distinguish observed differences from possible causes and to decide which application architecture and development workflow they would choose under stated constraints.
In this part, scalability has two connected objects of analysis. The first is the web application itself. The second is the development system around it. Application scalability remains the subject of the book; the three AI-assisted setups are the experimental lens. Students should be able to explain what the tools made easier, what they made riskier, and what project structures made the work legible enough to review.
