docs(10_Wiki): 위키 구조 정리 — 언어 튜토리얼 카테고리 폴더 제거 + 신규 자산 동기화

Topic_CSS/Topic_HTML/Topic_JavaScript/Topic_Prompt/Topic_Comfyui 등 기존 카테고리 폴더를 정리하고, Topic_Graphic/Dev 등 신규 산출물과 Topics 내부 세션/메모리 기록을 동기화.

+# [[Java Conditions Real Life]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+This chapter is a synthesis roundup — door-code checks, sign detection, voting eligibility, even/odd via modulo, temperature bands, and access control — showing that the entire if/else/else-if/nested-if/logical-operator toolkit converges on the same handful of real-world decision patterns. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Door code check** — equality comparison gating access. [S1]
+- **Positive/negative/zero classification** — three-way branch via if/else-if/else. [S1]
+- **Voting age check** — simple threshold comparison. [S1]
+- **Nested voting + citizenship** — combining nested if with else at each level. [S1]
+- **Even/odd via modulo** — `myNum % 2 == 0` as the even-test idiom. [S1]
+- **Temperature banding** — three-way else-if chain by numeric range. [S1]
+- **Access control** — `isLoggedIn && (isAdmin || securityLevel <= 2)`. [S1]
+
+## 🧩 추출된 패턴 (Extracted patterns)
+- **Modulo-based even/odd check** — `myNum % 2 == 0` is the canonical idiom, reused across virtually every language's conditions tutorial (same pattern in Python's chapters). [S1]
+
+## 📖 세부 내용 (Details)
+- Door code: `int doorCode = 1337; if (doorCode == 1337) { System.out.println("Correct code. The door is now open."); } else { System.out.println("Wrong code. The door remains closed."); }`. [S1]
+- Sign classification: `int myNum = 10; if (myNum > 0) {...} else if (myNum < 0) {...} else { System.out.println("The value is 0."); }`. [S1]
+- Voting age: `int myAge = 25; int votingAge = 18; if (myAge >= votingAge) { System.out.println("Old enough to vote!"); } else {...}`. [S1]
+- Even/odd: `int myNum = 5; if (myNum % 2 == 0) { System.out.println(myNum + " is even"); } else { System.out.println(myNum + " is odd"); }`. [S1]
+- Temperature bands: `int temperature = 30; if (temperature < 0) {...} else if (temperature < 20) {...} else { System.out.println("It's warm."); }`. [S1]

+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+소스에서 모순되는 정보는 발견되지 않음.
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 이 챕터 자체가 앞선 조건문 챕터들(If/Else/Else If/Nested If/Logical Operators)의 실전 종합 예제 모음이다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Even/odd via modulo (Java):
+```java
+int myNum = 5;
+if (myNum % 2 == 0) {
+    System.out.println(myNum + " is even");
+} else {
+    System.out.println(myNum + " is odd");
+}
+```

+## ✅ 검증 상태 및 신뢰도
+- **상태:** draft
+- **검증 단계:** conceptual
+- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
+- **신뢰 점수:** 0.87
+- **중복 검사 결과:** 신규 생성 (New discovery)
+
+## 🔗 지식 그래프 (Knowledge Graph)
+- **상위/루트:** [[Java Tutorial]]
+- **관련 개념:** [[Java If Else]], [[Java Nested If]], [[Java Conditions Logical Operators]], [[Java Switch]]
+- **참조 맥락:** 조건문 섹션 전체의 실전 종합 예제 — Switch 챕터로 이어짐.
