perf(network-graph): preserve duplicate memoization hypothesis provenance - #1632
Conversation
💡 무엇을: `NetworkGraph` 컴포넌트를 `React.memo()`로 감싸 불필요한 리렌더링을 방지했습니다. 🎯 왜: `NetworkGraph`는 무거운 `vis-network` 인스턴스를 다루며, 부모 컴포넌트인 `WorkspaceHome`이 대시보드 상태 변경 등으로 자주 리렌더링될 때 `NetworkGraph`도 계속 리렌더링되어 성능 저하와 레이아웃 스래싱을 유발하기 때문입니다. 📊 영향: 불필요한 DOM 조작 및 `vis-network` 인스턴스 재생성을 방지하여 렌더링 성능을 향상시킵니다. 🔬 측정: 빈번한 대시보드 업데이트 시 `NetworkGraph`가 다시 렌더링되는지 프로파일러를 통해 확인합니다.

…vening writer The branch advanced after the prior reconciliation with another memoization commit that reintroduced the unmeasured React.memo/layout-thrashing claim and, relative to #1622, also removed inherited security-floor tests and changed dependency/NetworkGraph source. Preserve that intervening commit as first-parent provenance, adopt current canonical provenance owner #1622 as second parent, and restore #1622's exact tree. No performance or dependency/security source remains independently owned by this lane.

The broad claim that unrelated
WorkspaceHomerenders repeatedly re-instantiatevis-networkis not established by the live component: construction is inside an effect bound to graph-state/derived-map dependencies.React.memo()could reduce render work, but no reality RED or measured buyer-path p95 evidence establishes a material causal benefit.After the earlier zero-delta reconciliation, this branch advanced again at
9e9e6fa...with the same unmeasuredReact.memo/layout-thrashing claim. Fresh comparison against #1622 also showed that this intervening state removed inherited frontend security-floor regressions, changed dependency manifests/lock/workspace data, removed the bounded NetworkGraph regression, and changedNetworkGraph.tsx. This was treated as an intervening delta to inspect and preserve in history, not as a race to overwrite.Ordinary two-parent repair
82c444593...keeps9e9e6fa...as first-parent provenance, adopts current #1622 as second parent, and points to #1622's exact tree. The branch advanced withforce=false. Fresh compare now reports no effective files, so no NetworkGraph implementation, test, dependency/security source, generated metadata, or performance claim is independently owned here.Keep Draft while #1622/#1593/#1623 remain unintegrated. Do not recreate memoization source unless a focused reality RED and measured buyer-visible performance result establish causal benefit while preserving graph correctness, selection behavior, accessibility, dependency-security floors, and
vis-networklifecycle cleanup. Historical generated/intervening checks are predecessor evidence only.No force-push, destructive rebase, dummy requeue, self-approval, gate weakening, duplicate owner source, dependency rollback, or unsupported layout-thrashing claim.
