+# ADOFAIRenderer API & Data Linking Exception (Dynamic Linking Only)
+
+> **Additional Permission under GNU General Public License version 3 section 7**
+
+---
+
+## 1. Legal Terms (Official)
+
+Linking this Program statically or dynamically with other modules is making a combined work based on this Program. Thus, the terms and conditions of the GNU General Public License cover the whole combination.
+
+As a special exception, the copyright holders of this Program give you permission to dynamically link this Program with independent modules that interact with or reference this Program solely through the public application programming interfaces (APIs), types, and data structures declared within the following namespaces:
+
+- `ADOFAIRenderer.API`
+- `ADOFAIRenderer.Data`
+
+and to copy, convey, and distribute the resulting combined work under terms of your choice, without requiring such combined work or independent modules to be covered under the GNU General Public License version 3, provided that you also meet, for each linked independent module, the terms and conditions of the license of that module.
+
+This exception applies exclusively to dynamic linking. Static linking, including but not limited to combining, embedding, compiling this Program into another binary, or merging assemblies (such as via ILMerge or Costura), is explicitly excluded from this exception and remains fully subject to the terms and copyleft requirements of the GNU General Public License version 3.
+
+An **"independent module"** is a separate and distinct software module that is not derived from or based on this Program, other than referencing or communicating with the interfaces and types declared within the designated namespaces above.
+
+This exception does not grant any permission to modify the source code of this Program itself outside the terms of the GNU General Public License version 3.
+
+In accordance with section 7 of the GNU GPL version 3, if you modify this Program, you may extend this exception to your version of the Program, but you are not obligated to do so. If you do not wish to provide this exception in your derivative work, you may remove this exception statement from your version.

+## 2. 조항 해설 (Korean Guide)
+
+본 문서는 GNU General Public License 버전 3 (GPLv3) 제7조(추가적인 허가, Additional Permissions)에 따라 제공되는 공식 예외 조항입니다.
+
+### 핵심 요약
+
+- **동적 링킹(Dynamic Linking)만 허용**:
+  - 본 예외 조항은 **동적 링킹(런타임 참조 및 어셈블리 동적 로드)**에만 배타적으로 적용됩니다.
+  - ADOFAIRenderer 또는 그 일부 코드를 대상 모드/프로그램에 직접 병합하거나 포함(ILMerge, Costura, 바이너리 직접 내장/정적 컴파일 등)하는 **정적 링킹(Static Linking)은 본 예외 대상에서 제외**되며, 순수 GPLv3의 카피레프트(전염성) 의무가 그대로 적용됩니다.
+- **외부 모드의 라이선스 자유**:
+  - 제3자 모드 또는 외부 프로그램이 동적 링킹을 통해 `ADOFAIRenderer.API` 및 `ADOFAIRenderer.Data` 네임스페이스의 공개 API, 클래스, 데이터 구조만을 참조·호출하여 연동하는 경우, 해당 모드는 **GPLv3의 카피레프트 의무를 적용받지 않습니다.**
+  - 외부 모드 개발자는 자신의 모드를 MIT, Apache-2.0, 독점/상용 라이선스 등 원하는 라이선스로 자유롭게 배포할 수 있습니다.
+- **ADOFAIRenderer 코어 보호**:
+  - ADOFAIRenderer 자체의 소스 코드(렌더링 파이프라인, 코어 패치, 내부 유틸리티 등)를 수정하거나 재배포하는 경우에는 본 예외 조항이 적용되지 않으며, 순수 GPLv3 라이선스 조건이 그대로 적용됩니다.
