…ering - Overhaul WritingFeelConfig: pressure gamma, velocity thinning, tilt, EMA smoothing - Add isFixedWidthConfig() detection for centerline vs polygon envelope rendering - Add buildVariableWidthPath with frozen prefix optimization for long strokes - Add arc-length resampling and velocity recomputation pipeline - Switch live path scheduling from rAF to queueMicrotask (1-frame latency reduction) - Convert live path from ref-based to state-based (skia v2 reconciliation requirement) - Add deferred SkPath dispose to prevent use-after-dispose in Skia Canvas - Add pencilOnly support in RNGH adapter with SharedValue for worklet access - Skip velocity computation and tilt calculation in fixed-width mode - Add eraser cursor visualization and React.memo on SkiaDrawingCanvasSurface Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- 버전 맞추기: reanimated ~4.1.6, gesture-handler ~2.28.0, typescript ~5.9.2 - podspec author/homepage/source를 team-ppointer로 변경 - useImperativeHandle stale ref 수정 (textBoxesRef 도입) - useTextBoxManager 인라인 객체 useMemo 감싸기 - TextBoxData 마이그레이션: width/height 없는 기존 데이터 fallback - committed paths dispose를 queueMicrotask로 지연 (live path과 동일 패턴) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
EraseStrokesEntry에 cachedPathsBefore 필드 추가. erase 시작 시 committedPaths 스냅샷을 history entry에 저장하고, undo 시 캐시된 paths를 직접 복원하여 O(ΣP) path rebuild 생략. - HistoryManager: cachedPathsBefore, onEntryEvicted 콜백, push/clear/discard 시 dispose - rendererTypes: replaceCommittedStrokes에 prebuiltPaths 파라미터, getCommittedPaths - useDrawingDocumentController: beginEraseTransaction/commitEraseTransaction 래퍼 - useDrawingInteractionController: docController 래퍼 호출로 변경 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
터치 이벤트를 Fabric EventEmitter 전에 native에서 인터셉트하여 path를 미리 빌드. JS는 getNativeLivePath()로 미리 빌드된 path를 사용. Native C++: - NativeDrawingSession: 포인트 축적, 속도 계산, frozen prefix path 빌드 - NativeDrawingLivePathBridge: thread-safe 정적 브릿지 (mutex + CallInvoker push) - StylusInputView: 터치 인터셉트, tilt 변환, config 동기화 (static activeView) JSI: - getNativeLivePath(): 최신 native path 복사 - setSessionConfig(): JS config → native session 동기화 - registerLivePathCallback(): CallInvoker push (Phase 3D, New Arch 미활성) TODO: Phase 3D New Arch CallInvoker 접근 방식 수정 (별도 PR) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Stroke.points/samples가 Point[]|Float64Array 둘 다 지원. 새 stroke는 finalizeStroke에서 Float64Array로 생성 (메모리 60-70% 절감, GC 0). - drawingTypes: packed stride 상수, pack/unpack 헬퍼, 접근 함수 - DrawingEngine: finalizeStroke에서 packPoints/packSamplesArray 사용 - strokeUtils: deepCopyStrokes, getStrokeBounds, getMaxY Float64Array 지원 - smoothing: buildSmoothPath/buildCenterlinePath union 시그니처 + unpack fallback - nativePathBuilder: packSamples Float64Array 직통 (re-pack 생략) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
JSON.stringify → binary packing (DataView + ArrayBuffer → base64). decode 시 자동 감지 (첫 바이트 0x01=binary, 그 외=legacy JSON). Float64Array stroke 직접 encode/decode (Phase 4-A 연동). - timestamp 정밀도: stroke별 baseTimestamp(float64) + delta offset(float32) - 색상 테이블: stroke color 중복 제거 - 하위 호환: 기존 JSON 데이터 + TextBoxData 마이그레이션 유지 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
TanStack Query 백그라운드 refetch 시 setStrokes 재호출 방지. initialLoadDoneRef로 초기 1회만 데이터 로드. 근본 해결: refactor/mat-313에서 useHandwritingManager 구조 리팩토링 필요. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- unused imports 제거 (useCallback, useRef, DocumentSnapshot, ReadonlyPoint) - unused destructuring에 _ prefix (historyRef, maxYRef) - no-explicit-any → HistoryEntry 타입 캐스팅 + eslint-disable 주석 - prettier 자동 포맷팅 적용 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Phase 4-D binary encoder → JSON 원복 (Float64Array→object 변환 후 JSON.stringify) - binary 데이터 감지 시 빈 캔버스로 fallback (테스트 중 저장된 binary 대응) - useDrawingState: markAsUnsaved 액션 추가 - ScrapDetailScreen: onChange → markAsUnsaved 연결 → autosave 활성화 - useHandwritingManager: unmount 시 저장 (뒤로가기/탭 전환 대응) - lastSavedDataRef 비교로 query refetch 시 중복 로드 방지 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
