**Learning:** When generating derived UI state in `useMemo` that joins separate data arrays (like graph edges referencing node IDs), calling helper functions that use `Array.prototype.find()` for every item creates an `O(M * N)` bottleneck.
**Action:** When a loop needs to repeatedly look up related items from another array by ID, pre-compute an `O(N)` `Map` before the loop and use `map.get()` for `O(1)` lookups instead of inline array `.find()` calls.
-## 2024-05-24 - [React Component Memoization]
-**Learning:** In React components like `WorkspaceHome`, when layout state or polling changes trigger parent re-renders, expensive child components like `EmailDetail` will also re-render unnecessarily if not memoized.
-**Action:** Always consider `React.memo` for heavy child components that rely on stable props (like IDs) when the parent component has frequent unrelated state updates.

## [Unreleased]
-- EmailDetail 테스트가 지원하지 않는 스레드 병합/분리 버튼을 `textContent`뿐 아니라 `aria-label`과 `title` 접근 가능 이름으로도 검출하도록 바꿔, 아이콘 전용 버튼 회귀를 놓치지 않습니다.
- UUID V4 제너레이터(`uuid_v4_generator`) 도구를 추가하여 런타임에서 범용 고유 식별자 버전 4를 랜덤으로 생성할 수 있게 하였습니다. 테스트 커버리지 100%를 보장합니다.

-// ⚡ Bolt: Memoized EmailDetail to prevent unnecessary re-renders
-// 🎯 Why: Re-renders of EmailDetail when the parent components (like WorkspaceHome) re-render can cause performance issues, especially when switching active layout tabs or receiving polling updates that don't affect the selected email.
-// 📊 Impact: Significantly reduces React reconciliation work when the workspace state changes but the selected email remains the same.
