3. Use GitHub Copilot Responsibly (15-20%)

This is the second-heaviest domain, and it's the one most students underestimate because it feels "soft." It isn't. Responsible use is the discipline that makes everything in Phase 2 safe to ship, and the exam tests it with concrete scenarios: a developer accepts an insecure suggestion, a model produces biased output, someone trusts a hallucinated API. The right answers almost never say "trust Copilot more." They say validate, oversee, and stay accountable. If you internalized Phase 1's point that Copilot is probabilistic, this entire phase is the practical consequence.
