### HTTP 헤더 기록 범위

원본 PDF에는 개별 HTTP request/response header 값이 기록되어 있지 않다. 원본 표의 `request_id`, `tool_uid`, `version`은 실행 메타데이터이며 HTTP header라고 단정하지 않는다.

원본 공통 안내에는 시크릿 및 인증 header가 로깅 전에 `[REDACTED]`로 마스킹되었다고 명시되어 있다. 따라서 Authorization, `Mcp-Session-Id` 등 실제 HTTP header 값은 이 문서에 포함하지 않는다.

## JSON-RPC 통신 전문

아래는 원본 PDF의 JSON-RPC 프레임을 순서대로 옮긴 전사본이다. 긴 `result.content[].text` 문자열은 PDF의 시각적 줄바꿈을 보존했으므로, 이 블록 전체를 기계 실행용 단일 JSON payload로 사용하지 않는다.
