💡 무엇을: NetworkGraph.tsx 내의 useMemo 훅에서 사용되던 체이닝된 배열 메서드 (.map().filter().slice() 및 Array.from().slice().map())를 for...of 루프와 조기 종료(early break)를 사용하는 방식으로 리팩토링했습니다.

🎯 왜: 기존 방식은 맵이나 배열 전체를 순회하고 불필요한 중간 배열을 할당하여 O(N)의 비용이 발생했습니다.

📊 영향: 큰 그래프 데이터를 다룰 때 노드와 엣지 옵션을 생성하는 비용을 O(N)에서 O(1) (상수 시간)로 단축하여 컴포넌트 렌더링 성능이 향상되었습니다.

🔬 측정: 전체 테스트 및 린트 통과 확인 완료.

Summary by CodeRabbit

  • Performance
    • Improved efficiency when preparing network graph labels, relationships, and node options. This can reduce unnecessary work when graphs contain many available items. The graph still shows up to five labels, five relationships, and eight nodes; empty labels are omitted, and relationship numbering and displayed labels remain unchanged.

Walkthrough

NetworkGraph now builds node labels, relationship options, and node options with bounded loops. The existing limits and displayed values remain unchanged. A guidance note describes using early-break loops when selecting a small number of items from a large iterable.

Changes

Network Graph option lists

Layer / File(s) Summary
Build bounded option lists
.jules/bolt.md, frontend/src/components/NetworkGraph.tsx
nodeLabels, relationshipOptions, and nodeOptions use loops that stop after five, five, and eight entries. They preserve existing filtering, numbering, and option values. The guidance note describes early-break loops for small-result selection.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Refactor



Merge Risk: 🔵 Low · up to 562e2

The guidance overstates the filtered label loop’s performance: sparse nonempty labels can require scanning every node. Correct this localized caveat; it does not prevent the graph from rendering.

complexity claim: when filtering out empty labels and stopping after five
nonempty results, the loop may scan k nodes and has O(N) worst-case traversal if
fewer than five qualify. Limit the O(1) claim to unfiltered bounded iteration.

## 2024-10-11 - Replaced O(N) chained operations with O(1) early-break loops in NetworkGraph
**Learning:** Chained array methods (like `Array.from(map.values()).slice(0, N).map(...)`) iterate the entire Map unnecessarily, causing O(N) allocation before taking a tiny slice.
**Action:** Use a `for...of` loop inside a `useMemo` block with an early `break` condition (e.g., `if (results.length >= N) break;`) when taking a small slice of a large iterable.

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win

Qualify the O(1) claim for filtered results.

In frontend/src/components/NetworkGraph.tsx, Line 284 skips empty labels, and Line 286 stops only after collecting five nonempty labels. If fewer than five labels are nonempty, the loop scans all nodes. Describe this case as O(k), with O(N) worst-case traversal, or limit the O(1) claim to unfiltered bounded iteration.
