+## 핵심 요약 (specialization aspects)
+- 매 immutability — 매 생성 후 변경 불가 → 매 reasoning/concurrency/cache 에 매 결정적 이득.
+- 매 TypeScript level: `readonly` modifier · `Readonly<T>` · `as const` · `ReadonlyArray<T>`.
+- 매 runtime level: `Object.freeze` · structural sharing (Immer/Immutable.js).
+- 매 React state · Redux reducer · Zustand store 의 매 핵심 invariant.
+
+## 🔗 Graph
+- 부모: [[Readonly 유틸리티 타입]] (canonical)
+- Adjacent: [[as const Assertion]] · [[SOLID 원칙]] · [[Result Type]]
