## Output Schema
{
  "intent": "fact_lookup | semantic_search | filter_browse",
  "query_type": "natural_language | keyword | phrase",
  "domain_hint": "document | news | mixed",
  "language_scope": "limited | global",
  "keywords": [],
  "must_terms": [],
  "optional_terms": [],
  "hard_filters": {},
  "soft_filters": {"domain": [], "document_type": []},

}

## Rules
- `intent`: fact_lookup (사실/조항/이름), semantic_search (주제/개념), filter_browse (필터 중심)
- `query_type`: natural_language (문장형), keyword (단어 나열), phrase (따옴표/고유명사/법조항)
- `domain_hint`: document (소유 문서/법령/매뉴얼), news (시사/뉴스), mixed (불명)
- `language_scope`: limited (ko+en), global (다국어 필요)
- `hard_filters`: 쿼리에 **명시된** 것만. 추론 금지. 키: file_format, year, country
- `soft_filters.domain`: Industrial_Safety, Programming, Engineering, Philosophy, Language, General. 2-level 허용(e.g. Industrial_Safety/Legislation)
- `soft_filters.document_type`: Law_Document, Manual, Report, Academic_Paper, Standard, Specification, Meeting_Minutes, Checklist, Note, Memo, Reference, Drawing, Template
- `normalized_queries`: 원문 언어 1.0 가중치 필수. 교차언어 1개 추가 권장(ko↔en, weight 0.8). news + global 인 경우만 ja/zh 추가(weight 0.5~0.6). **최대 3개**.
- `analyzer_confidence`: 0.9+ 명확, 0.7~0.9 대체로 명확, 0.5~0.7 모호, <0.5 분석 불가
