- 옮김: B04 2 · B05 23 · B06 11 · A00_Common/design 13 (9,299 줄) · 이미 logic/ 에 있던 16 파일 그대로
- 안 옮김: 묶음 입구(package.json build:*) · 파이썬 · 순수지만 계산 아닌 8 (보기 결선 · 콜백 · API 타입 · 갈아끼움 알림판)
- import 266 줄(142 파일) · 시험 · 주석 · 짝 표시 문자열 경로 고침 · B05 · B06 CLAUDE.md 짝 줄 logic/
- 시험 도우미 새 경로: 가짜 require 열쇠 · B05()/B06() 부름 · 형제 import 자리 · tsc 묶어 돌리는 시험 · 정규식 · rglob
- design_view_cross 줄 한도 시험 685 → 688 (긴 import 경로 줄바꿈 3줄)
- 확인: typecheck 0 · 서버 묶음 넷(corridor · server-calc · b07-extent · b07-note) 다시 지어 코드 같음(//#region 경로 주석만 다름) · 관련 시험 270 파일 — 남은 실패 19 는 옮기기 전과 같음
