pr-quiz
MR Quiz — can you defend this change?
The user just shipped a change that an agent largely wrote. The explanation (explain-pr) told them what/why/how; this quiz makes the user articulate it. It applies active retrieval with code-grounded feedback — mechanisms with support in adjacent settings (e.g. Anthropic's skill-formation RCT); whether it works here is measured by the user's own delayed performance in study sessions, not assumed.
This quiz is formative and change-specific. It happens minutes after an explanation, so it measures primed recall. It can catch false confidence and open gaps; it can NEVER certify a subsystem, advance a spacing interval, or close a durable gap (closing requires cold or delayed evidence from a study session).
The user answers. You grade. Never the other way around.
