Research note, 6 Oct 2026. The 500 outputs of the study re-read for hallucinated package names: none. The 250 outputs with a specification imported no third-party package at all, for every model. Script and results included.
ETH Zurich measured context files across 438 tasks: no lift, +20% cost — for generated and hand-written files alike. What a context file is actually for, per Delta’s Law 4.
Why AI assistants default to binary floats for money, the defect class it creates, and the two-move fix from Delta’s Law 5.
The quiet failure mode of AI-assisted development — and the one-page discipline that prevents it. From Delta’s Law 4.
A twenty-minute, four-block method for getting production-grade code from AI assistants. Condensed from Delta.
