🔐 자메스 (James) - 통합 보안 테스트 (Phase 4)
========================================
실행: python james_security_test.py
     python james_security_test.py --server  (서버 API 테스트)

Phase 4 신규 섹션:
  5. SEC-FIX 1,2,3 검증 (기존 테스트 오탐 수정 포함)
  6. Instruction Isolation [P4-SEC-1]
  7. ABAC 3단계 일관성 [P4-SEC-2]
  8. 서버 보안 — Rate Limit + 감사로그 + Write 분리 + X-Role

핵심 수정:
  기존 t_sl_admin_allowed: admin 공격 허용을 PASS로 기대 → Phase 4 반대 (차단)
  SEC-FIX-1: admin도 injection 차단
  SEC-FIX-2: post_check user_role 전달 검증
