Concept — nornen-stock ETF portfolio sleeve

한 줄: ETF는 총자산 mix의 한 축(섹터 active / 인덱스 참여 / 현금과 함께). shadow→env-gated paper 경로.

단계

premarket universe (no lev/inv; rep by 거래대금)
→ freeze
→ intraday state/range/portfolio_mix
→ (optional) env-gated paper order events
→ /etf-ops UI + order_candidate_preview (no side effect)

안전

• research artifact 기본 read-only
• order는 ETF_* + KIS shared gates
• preview 카운트 ≠ submit
