feat(report): 적산(.QV) 정확 메트릭 + 물질수지 폐합 + 웹 대시보드

PV-중앙값 근사 대신 유량 적산(.QV)으로 정확한 적분 메트릭 추가, 웹에서 바로 보기.

- QV 메트릭 4종: production_total·yield_qv·energy_intensity_qv·mass_balance_closure.
  적산 Δ 헬퍼(QvDeltaAsync)는 값 급감(reset/wrap)으로 구간분할 후 구간별 (마지막-처음)
  합산 → gap·양자화 강건, DCS 일일적산과 동일 의미(노이즈 과대계상 없음).
- 매핑은 appsettings SteamAdvisor:Columns 재사용(.QV 치환, 7컬럼). 폐합 스트림은
  Report:Closure:C-6111(Feed + Outputs[제품·경비물·중비물]).
- 웹 대시보드: GET /api/report/columns, /api/report/summary →
  리포트 탭에서 컬럼·날짜 선택 시 물질수지 신뢰블록(IN/OUT/폐합%, 98~101% 색상)
  + 메트릭 표를 즉시 렌더. 엑셀 export와 병존.
- 물리적 타당성 게이트: 수율>1.5·에너지원단위>5·≤0 → no_data+사유(garbage 차단).

검증(2026-05-15 C-6111): 생산 8455kg·수율 0.8739·에너지 0.7791·폐합 99.04%
(feed 9675/out 9582), 17주 폐합 99.1~99.8%. C-9111 garbage 수율 → no_data 처리 확인.

 추정: 백엔드 핵심(메트릭+채움+컨트롤러) ~1.5일, store/DDL ~0.5일, 프론트 ~0.5일, 검증/데모 ~0.5일 → **약 3일**.
 
+## 12. 적산(.QV) 메트릭 추가 (2026-06-13 구현)
+
+각 유량태그의 `.QV`(적산/totalizer)를 활용. PV-중앙값 근사 대신 **정확한 적분** → gap·양자화 무관, "비율의 중앙값" 모호성 해소. 폐합이 닫혀(99.1~99.8%) 적산기 신뢰성도 입증됨.
+
+**추가 메트릭(4종):**
+| metric | 정의 | 비고 |
+|---|---|---|
+| `production_total` | ΔQV(제품) | 생산량 kg = MES 생산리포트 숫자 |
+| `yield_qv` | Δproduct/Δfeed | 정확 수율 |
+| `energy_intensity_qv` | Δsteam/Δproduct | 정확 에너지원단위 |
+| `mass_balance_closure` | 100·ΣΔout/Δfeed | 폐합 % + Extra(feed_qv/out_total/out0~2_qv) |
+
+**적산 Δ 헬퍼(`QvDeltaAsync`)** — 핵심. 값 급감(<prev−1)으로 **리셋/wrap 구간 분할 후 구간별 (마지막−처음) 합산**:
+- gap 강건(끝점 차이가 정답), 노이즈 과대계상 없음(=DCS 일일적산과 동일 의미), wrap(1e6) 꼭대기 잔량(소량)만 손실.
+- 검증(2026-05-15 C-6111): production 8454.7kg·yield 0.8739·energy 0.7791·closure 99.04%(feed 9675/out 9582). 폐합 17주 99.1~99.8%.
+
+**매핑 재사용:** production/yield/energy = `SteamAdvisor:Columns`의 Feed/Product/SteamFlow를 `.QV`로 치환(7컬럼 무료). 폐합은 신규 `appsettings:Report:Closure:{col}`(Feed + Outputs[제품,경비물,중비물]) — C-6111만 등록(타컬럼은 P&ID 그래프 유도 후 확장).
+
+**신뢰 블록(운전원 검산):** 템플릿에 `feed_qv`(IN)·`out_total`(OUT)·`mass_balance_closure`(%)를 한 표에 배치 → "9675 vs 9582 = 99% 닫힘"을 눈으로 검산. 샘플 템플릿에 반영.
+
 ## 11. 다음(P1 훅)
 - `dynamics` 메트릭(fast_record 전용, FOPDT/stiction) — 같은 인터페이스에 metric 1개 추가.
 - 토큰에 `period=MONTHLY|YEARLY` 추가 → from/to 계산만 분기.
