scripts/analyze-playtest-attempts.py auto-derives the protocol metrics from attempts.csv: per-session learning curve (RQ1), before/after-hint success rates (RQ2), per-family first-attempt success and confusion matrix (RQ3), failure type distribution, assist reach, stuck points, and SUS scoring. Stdlib only; verified against synthetic data. RESEARCH_PROTOCOL gains the SUS-10 questionnaire (Korean), a behavioral feedback-comprehension coding procedure (stated fix vs actual next attempt), and analysis steps. FINAL_REPORT metrics table updated to match.

요약
HCI 평가에서 실험 설계를 보강하는 3가지를 추가합니다.
1.
scripts/analyze-playtest-attempts.py(표준 라이브러리만 사용)attempts.csv에서 프로토콜 지표를 자동 산출:
--sus로 SUS 표준 채점 (홀짝 보정 ×2.5)합성 데이터로 end-to-end 검증 완료.
2. RESEARCH_PROTOCOL — SUS-10 한국어 문항 추가
커스텀 5문항만으로는 외부 비교 기준이 없어, 표준 척도(기준선 68)를 사후 설문에 추가.
3. RESEARCH_PROTOCOL — 피드백 이해도의 행동 측정
"다음에 뭘 바꿀 건가요?" 발화와 다음 시도의 실제 변화를 대조 코딩 — 자기보고+행동 이중 측정.
FINAL_REPORT §5.2 지표 표도 동기화.
