💡 무엇을: NetworkGraph.tsx 내의 노드 라벨 검색 과정을 최적화하여 배열 선형 탐색을 O(1) 해시맵 조회로 교체했습니다.
🎯 왜: 기존 구조에서는 엣지의 양 끝 노드 이름을 찾기 위해 Array.prototype.find()를 호출하여 O(N) 복잡도가 발생했고, 이를 맵핑 과정에서 반복 호출하여 O(E * N) 성능 병목을 야기했습니다. 이를 Map 객체 기반의 O(1) 검색으로 개선했습니다.
📊 영향: 관계 렌더링의 시간 복잡도를 O(E * N)에서 O(N + E)로 줄여 메인 스레드 멈춤 현상을 방지하고 빠른 렌더링을 보장합니다.
🔬 측정 방법: 1만 개 이상의 노드/엣지가 포함된 대형 관계 데이터 렌더링 시 CPU 사용률 및 메인스레드 차단 시간 측정.

📝 Walkthrough

Walkthrough

The PR optimizes relationship label lookups in NetworkGraph with a memoized node map. It also adds diagnostic scripts for HTML-like text parsing, tag stripping, and masked-email restoration.

Changes

Network graph lookup optimization

Layer / File(s) Summary
Map-backed edge label resolution
.jules/bolt.md, frontend/src/components/NetworkGraph.tsx
describeEdge accepts an optional node label map. NetworkGraph builds the map and uses it for graph selection, relationship options, and programmatic relationship selection. The performance guidance documents the lookup pattern.

HTML-like text parser diagnostics

Layer / File(s) Summary
Parser diagnostic scripts
test_parse.py, test_parse2.py, test_parse3.py
Standalone scripts process comment and script-like markup, print parser results, strip tag-like segments, and restore masked emails.

266-275: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Hoist the node map for every relationship-label path.

The map is local to relationshipOptions, and that memo formats only edges.slice(0, 5). selectEdge at Line 199 and selectRelationship at Line 290 still call describeEdge(edge, nodes) without the map, so those interaction paths still scan nodes. If the objective is O(1) endpoint lookup throughout relationship rendering, build the map in a useMemo keyed by nodes and pass it to every describeEdge call. Otherwise, narrow the performance claim to the five relationship options.

Proposed map reuse
+  const nodeMap = useMemo(() => {
+    const map = new Map<string, string>();
+    for (const node of nodes) {
+      if (node.id != null) {
+        map.set(String(node.id), String(node.label ?? node.id));
+      }
+    }
+    return map;
+  }, [nodes]);
+
   const relationshipOptions = useMemo(() => {
-    const nodeMap = new Map<string, string>();
-    for (const node of nodes) {
-      if (node.id != null) {
-        nodeMap.set(String(node.id), String(node.label ?? node.id));
-      }
-    }
     return edges.slice(0, 5).map((edge, index) => ({
       edge,
       id: String(edge.id),
       label: `관계 ${index + 1}: ${describeEdge(edge, nodes, nodeMap)}`,
     }));
-  }, [edges, nodes]);
+  }, [edges, nodes, nodeMap]);

Pass nodeMap to the describeEdge calls in the selection paths and include it in the effect dependencies.

⚠️ Unverified finding
Sandbox verification was unavailable.

Verify uniqueness after ID normalization.

nodeMap.set(String(node.id), ...) overwrites earlier labels when two node IDs normalize to the same string, such as 1 and "1". The current findNodeLabel path returns the first matching node. Confirm that sanitizeNetworkData rejects duplicate normalized IDs before rendering.

5-16: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

⚠️ Unverified finding
Sandbox verification was unavailable.

Keep standalone diagnostics out of automatic test discovery. These files match the test_*.py pattern but execute code during import. If CI uses pytest's default discovery, collection runs the diagnostics and can fail on import or parser errors.

  • test_parse.py#L5-L16: move the diagnostic outside test discovery or add a main() guard.
  • test_parse2.py#L5-L6: move the diagnostic outside test discovery or add a main() guard.
  • test_parse3.py#L5-L24: move the diagnostic outside test discovery or add a main() guard.

- Around line 2-3: Update the import setup in test_parse.py lines 2-3,
test_parse2.py lines 2-3, and test_parse3.py lines 2-3 to derive the backend
directory from each script’s __file__ location and insert it before existing
sys.path entries, ensuring the services.text_safety imports resolve consistently
regardless of the caller’s working directory.

In `@test_parse3.py`:
- Around line 7-8: Update the diagnostic flow around _mask_angle_emails to
restore its placeholders after the stripping loop, matching backend text-safety
behavior. Apply the restoration before printing the final text so angle-bracket
email inputs produce the same result as strip_html_markup.
