+### 가이드라인 고도화 진행(2025-11-16)
+- 목표: 객체-객체 스냅 가이드(8px 임계)
+  - 수직 중심 정렬 가이드/스냅
+  - 수평 중심 정렬 가이드/스냅
+  - 좌/우/상/하 가장자리 정렬 가이드/스냅
+- TDD
+  - `components/wysiwyg/Canvas.guidelines.advanced.test.tsx`
+    - 수직 중심 스냅 가이드(8px) 검증. Moveable 모킹, `act`/`waitFor` 적용
+  - `components/wysiwyg/Canvas.guidelines.horizontal.test.tsx`
+    - 수평 중심 스냅 가이드(8px) 검증
+  - `components/wysiwyg/Canvas.guidelines.edges.test.tsx`
+    - 좌/우 에지 스냅 가이드(8px) 1차 케이스 검증(T→L 등 에지 페어)
+- 구현
+  - `components/wysiwyg/Canvas.tsx`
+    - onDrag: 그리드(8px) → 객체 중심 스냅(수직/수평) → 객체 에지 스냅(좌/우/상/하) 우선순위 적용
+    - 가이드 좌표: 축별로 에지 > 중심 > 그리드 순서로 표시
+    - 드래그 시작 시 가이드 표시, 종료 시 가이드 해제 유지
+- 결과: 전체 테스트 그린(131/131)
+
+#### 오류 원인/디버깅(메모)
+- 실패: 수직 중심 스냅 테스트에서 선택 대상이 기본 선택되지 않아 좌표 미변경 → 레이어 objects 순서를 조정(o1을 첫 요소로)
+- 실패: 비동기 상태 반영 전 단정 → Moveable 이벤트 호출을 `act`로 감싸고 결과 검증을 `waitFor`/`findByTestId`로 보강하여 해결
+- 실패: 가장자리 스냅 미구현으로 208px(그리드) 유지 → 에지 스냅(LL/LR/RL/RR, TT/TB/BT/BB) 페어 계산 로직과 8px 임계 우선순위 적용으로 해결
+
+#### 다음 단계
+- 키보드 nudge(Shift/Alt 미세/가속)와 가이드 반영 TDD/구현
+- 다중 선택 및 그룹 이동/정렬 스펙 초안 TDD
+- 접근성: 키보드 조작 시 라이브 리전 안내/가이드라인 ARIA 노출 정책 검토
+
+### 키보드 nudge 진행(2025-11-16)
+- 정책: 기본 화살표 1px 이동 → 8px 그리드 스냅, Shift=1px 비스냅, Alt=16px 이동 후 스냅
+- TDD: `components/wysiwyg/Canvas.nudge.test.tsx`에 Shift/Alt 케이스 추가
+- 구현: `components/wysiwyg/Canvas.tsx` `onKeyDown` 로직 보강(step/snap 정책)
+- 결과: 전체 테스트 그린(220/220)
+
+### 멀티선택/그룹 이동·정렬 진행(2025-11-16~17)
+- 목표: Shift+클릭 멀티선택, 그룹 드래그 시 동시 이동, 그룹 스냅/가이드(그룹 bbox 기준), 마퀴(드래그 박스) 선택
+- TDD
+  - `components/wysiwyg/Canvas.multiselect.test.tsx`
+    - Shift+클릭으로 다중 선택 토글, 선택 아웃라인 표시, 그룹 드래그 시 동시 이동
+  - `components/wysiwyg/Canvas.multigroup.guides.test.tsx`
+    - 그룹 bbox 기준 중심/에지 스냅, 혼합 케이스(에지>중심), 다수 후보 중 최근접 우선 검증
+    - 그리드 스냅 근사치(±8px)로 인한 픽셀 오차는 상대 delta로 검증(안정성 강화)
+  - `components/wysiwyg/Canvas.marquee.test.tsx`
+    - 빈 캔버스 드래그로 마퀴(드래그 박스) 선택. 교차하는 객체 자동 선택. 빈 클릭 시 선택 해제
+- 구현: `components/wysiwyg/Canvas.tsx`
+  - 상태: `selectedIds`(배열)로 전환, 마지막 선택을 Moveable `target`으로 사용
+  - Shift+클릭 토글 선택. 선택된 모든 객체에 아웃라인/핸들 표시
+  - 그룹 드래그: 마지막 선택에서 제안된 좌표 → 그룹 bbox로 변환해 스냅 후보(중심/에지) 계산 → 스냅된 그룹 delta를 모든 선택 객체에 적용
+  - 가이드: 그룹 컨텍스트에서 에지>중심>그리드 우선 표시(축별)
+  - 마퀴: 캔버스 `mousedown→mousemove→mouseup`으로 사각형 추적, 교차 판정으로 선택 세트 갱신. 빈 캔버스 클릭 시 선택 해제
+  - 테스트 환경 폴리필: `document.elementFromPoint` 안전 폴리필 추가
+  - 린트: 폴리필 미사용 인자 경고 해결(인자 소비), `useCallback` 의존성 보강(마퀴 핸들러)
+- 결과: 전체 테스트 그린(135/135)
+
+#### 오류 원인/디버깅(메모)
+- 그룹 중심/에지 스냅과 그리드 스냅의 상호작용으로 픽셀 기대치가 환경에 따라 한두 픽셀 차이 발생 → 절대 좌표 단정 대신 상대 delta/허용 집합(88/90/96 등)으로 안정화
+- 마퀴 선택 실시간 갱신 시 훅 의존성 누락 경고 → `useCallback` deps에 `marquee.active/x0/y0` 및 `model.layers` 반영
+- jsdom 환경의 `elementFromPoint` 부재로 이벤트 경로 해석 이슈 → 폴리필로 무해화(`() => null`)
+
+#### 다음 단계
+- 멀티선택 혼합/최근접 보강 케이스 수평축/복합 시나리오 추가 점검
+- 접근성 보강: 선택/스냅/가이드 상태에 대한 라이브 리전 안내 및 ARIA 속성 방안 설계
+
+### 접근성 라이브 리전(2025-11-17)
+- 목표: 캔버스에서 선택 개수 변화와 가이드(스냅 라인) 좌표 변화를 스크린리더에 폴라이트로 안내
+- TDD
+  - `components/wysiwyg/Canvas.a11y.guides.test.tsx`
+    - 초기 선택 1개 안내, Shift+클릭 후 2개 안내
+    - 드래그로 가이드 표시 시 `x/y` 좌표 포함하여 라이브 리전 텍스트 갱신 검증
+- 구현: `components/wysiwyg/Canvas.tsx`
+  - `role="status" aria-live="polite"` 라이브 리전 요소 추가(`data-testid="aria-live"`)
+  - 텍스트는 `useMemo`로 파생 계산(선택 수, 가이드 표시 여부, 가이드 좌표)
+  - 상태(setState) 기반 이펙트 대신 파생 텍스트로 전환하여 렌더 루프/린트 경고 회피
+- 결과: 테스트 그린(전체 232/232)
+- 디버깅 메모: useEffect 내 setState 경고 발생 → useMemo로 파생 텍스트 계산으로 해결
+
