⚡ Bolt: [성능 개선] NetworkGraph 컴포넌트 memoization 적용

• canonical NetworkGraph memo owner / current base: perf(frontend): memoize NetworkGraph render boundary #1675 7926361f97a7c8ea494440b266d8b8ad654dc335
• canonical owner tree: db81645977cbddd363e592633d11377b46ec6207
• generated regression remains ancestry evidence
• prior zero-delta provenance: f1105c3fe836e8b526628794229758e7dc70d212
• ordinary/non-force restack / exact current head: f69c870b5669283a46252820cf6f433404fccc2f
• lifecycle: Draft / generated zero-effective-delta provenance / do not merge independently

This generated memo lane had already been repaired back to the #1675 tree after broad cross-owner drift. Because the canonical NetworkGraph owner chain moved again, it followed current #1675 ordinary/non-force. Exact current tree remains the memo-owner tree and effective delta remains zero.

Historical workflow/review receipts do not transfer to #1675 or protected integration and do not prove buyer-visible p95/main-thread improvement. Keep Draft until #1675 normally integrates or a verified complete successor inherits source, regression, review, hosted execution and claimed performance evidence. No duplicate source writer, source-neutral wake commit, stale evidence transfer, self-approval, synthetic status, force push/destructive rebase or gate weakening.

📝 Walkthrough

Walkthrough

NetworkGraph now uses React.memo, which prevents re-renders when its parent updates without changing its props. A dated learning note documents this pattern for heavy third-party visualization wrappers.

Changes

NetworkGraph memoization

Layer / File(s)	Summary
Memoized NetworkGraph export frontend/src/components/NetworkGraph.tsx, .jules/bolt.md	The component imports memo and exports NetworkGraph through memo. The learning notes document the same optimization for visualization wrappers.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Refactor

Possibly related PRs

• ContextualWisdomLab/naruon#1703: Applies the same React.memo export change to NetworkGraph.
• ContextualWisdomLab/naruon#1658: Applies React.memo to NetworkGraph for the same re-render behavior.
• ContextualWisdomLab/naruon#1598: Wraps NetworkGraph in React.memo to prevent unnecessary re-renders.

Merge Risk: 🔵 Low · up to 121d4

The optimization is low risk, but a focused render-level test is needed to prevent future changes from silently reintroducing expensive renders.

rerenders its parent with unchanged props and verifies the NetworkGraph render
is skipped, rather than only asserting one-time vis-network initialization.
Anchor the test to NetworkGraph and the existing Network call-count assertions,
