"""GovOn Native Tool Calling + AdapterRegistry E2E 검증 스크립트.

HuggingFace Space에 배포된 govon-runtime 서버에 대해
에이전트 파이프라인(플래너 → 도구 실행 → 어댑터 전환)을 검증한다.

사용법:
    GOVON_RUNTIME_URL=https://<space-url>.hf.space python3 scripts/verify_e2e_tool_calling.py
    GOVON_RUNTIME_URL=https://<space-url>.hf.space API_KEY=<key> python3 scripts/verify_e2e_tool_calling.py

5-Phase 검증 (16 시나리오):
    Phase 1: Infrastructure (hard gate)
        1. Health & Profile
        2. Base Model Generation
        3. Adapter Registry
    Phase 2: Agent Pipeline Core
        4. Planner Produces Valid Plan
        5. Civil LoRA Draft Response
        6. Legal LoRA Evidence Augmentation (depends on 5)
        6a. Legal LoRA — 민사법 (Civil Law)
        6b. Legal LoRA — 형사법 (Criminal Law)
        6c. Legal LoRA — 지식재산권 (IP)
        6d. Legal LoRA — 판례 해석 (Precedent)
        7. Task Type Classification
    Phase 3: data.go.kr API Tools (soft gate)
        8. External API Tool Invocation (4 sub-cases)
    Phase 4: Adapter Dynamics
        9. Sequential Adapter Switching
        10. LoRA ID Consistency
    Phase 5: Robustness
        11. Empty Query Handling
