Quiz — add opcode

Question

Confirm: 5-step buildup + 2 macros + load-bearing details.

Principle (minimum model)

• Buildup steps + popn_top! + gas! + unwrap_unchecked justification + cold_path() + why macros.

Worked example + steps

Quiz: did add actually stick?

This quiz isn't decoration. It exists because the previous two lessons' "predict" prompts are easy to nod past — and a day from now, "I read it, nodded, and couldn't reproduce it" is the failure mode that breaks Intermediate.

Five questions, covering both the build-up and the macro refactor. If you find yourself guessing, stop and re-read the relevant section before answering. The quiz will still be here.

If you miss two or more, the lessons haven't internalized — re-read both Building add step by step and Reading add: factoring out the macro before going on to the drill.

Summary (3 lines)

• Quiz confirms add opcode understanding.
• Get two+ wrong → re-read buildup + macro lessons.
• Pass → drill: prove you can read interpreter source.
