+## 2. 구현 갭 상세
+
+### GAP-1: DecisionLogger에 session_id 미포함 (CRITICAL)
+
+- **위치**: `src/logging/decision_logger.py:40`
+- **문제**: `log_decision()` 함수에 `session_id` 파라미터가 없음
+- **영향**: 어떤 세션에서 전략적 의사결정이 내려졌는지 추적 불가
+- **요구사항**: REQ-V3-001
+
+### GAP-2: src/main.py 거래 로그에 session_id 미전달 (CRITICAL)
+
+- **위치**: `src/main.py` line 1625, 1682, 2769
+- **문제**: `log_trade()` 호출 시 `session_id` 파라미터를 전달하지 않음
+- **현상**: 시장 코드 기반 자동 추론에 의존 → 실제 런타임 세션과 불일치 가능
+- **요구사항**: REQ-V3-001
+
+### GAP-3: 세션 전환 시 리스크 파라미터 재로딩 없음 (HIGH)
+
+- **위치**: `src/main.py` 전체
+- **문제**: 리스크 파라미터가 시작 시 한 번만 로딩되고, 세션 경계 변경 시 재로딩 메커니즘 없음
+- **영향**: NXT_AFTER(저유동) → KRX_REG(정규장) 전환 시에도 동일 파라미터 사용
+- **요구사항**: REQ-V3-002
+
+### GAP-4: 블랙아웃 복구 시 재검증 부분 해소, DB 기록 미구현 (HIGH)
+
+- **위치**: `src/core/blackout_manager.py:89-96`, `src/main.py:694-791`
+- **상태**: `pop_recovery_batch()` 자체는 단순 dequeue이나, 실행 경로에서 부분 재검증 수행:
+  - stale BUY 드롭 (포지션 이미 존재 시) — `src/main.py:713-720`
+  - stale SELL 드롭 (포지션 부재 시) — `src/main.py:721-727`
+  - `validate_order_policy()` 호출 — `src/main.py:729-734`
+- **잔여 갭**: 가격 유효성(시세 변동), 세션 변경에 따른 파라미터 재적용은 미구현
+- **신규 발견**: 블랙아웃 복구 주문이 `log_trade()` 없이 실행되어 거래 DB에 기록되지 않음 → 성과 리포트 불일치 유발
+- **요구사항**: REQ-V3-004
+
+### GAP-5: 시간장벽이 봉 개수 고정 (MEDIUM)
+
+- **위치**: `src/analysis/triple_barrier.py:19`
+- **문제**: `max_holding_bars` (고정 봉 수) 사용, v3 계획의 `max_holding_minutes` (캘린더 시간) 미반영
+- **요구사항**: REQ-V2-005 / v3 확장

+
+### 3.3 시장별 손익
+
+| 시장 | 매도 수 | 승률 | 총 손익 |
+|------|---------|------|---------|
+| **KR** | 17 | 38.5% (0손익 제외, 5/13) | **-56,735 KRW** |
+| US_AMEX | 12 | 75% | +4,476 USD |
+| US_NASDAQ | 4 | 0% | -177 USD |
+| US_NYSE | 13 | 30.8% | -45 USD |
+
+**KR 시장이 손실의 주 원인.** US는 AMEX 제외 시 대체로 손실 또는 보합.
+
+### 3.4 재계산 주석 반영 (통화 분리)
+
+> 산식 주석: 기존 표의 `총 실현 손익 -52,481`은 KRW/USD를 단순 합산한 값으로, 회계적으로 해석 불가.
+> 아래는 같은 기간(2026-02-25~2026-02-27, SELL 45건)을 통화별로 분리한 결과.
+
+| 통화 | 매도 수 | 승/패 | 실현 손익 |
+|------|---------|-------|-----------|
+| KRW | 17 | 5승 / 8패 (4건 0손익) | **-56,735 KRW** |
+| USD | 28 | 13승 / 14패 (1건 0손익) | **+4,253.70 USD** |
+
+### 3.5 재계산 주석 반영 (기존 보유 청산 성과 분리)
+
+> 분리 기준: 각 SELL의 직전 BUY가 `rationale LIKE '[startup-sync]%'` 인 경우를
+> `기존 보유(시작 시점 동기화 포지션) 청산`으로 분류.
+
+| 구분 | 통화 | 매도 수 | 손익 |
+|------|------|---------|------|
+| 기존 보유 청산분 | KRW | 10 | **+12,230 KRW** |
+| 기존 보유 청산분 | USD | 2 | **+21.03 USD** |
+| 신규/전략 진입분만 | KRW | 7 | **-68,965 KRW** |
+| 신규/전략 진입분만 | USD | 26 | **+4,232.67 USD** |
+
+추가로, 요청 취지(“기존 보유 수익 종목 정리 수익 제외”)에 맞춰 **기존 보유 청산 중 수익(+PnL)만 제외**하면:
+
+- KRW: `-56,735` → **-113,885 KRW** (기존 보유 수익 +57,150 KRW 제거)
+- USD: `+4,253.70` → **+4,232.67 USD** (기존 보유 수익 +21.03 USD 제거)
+
+즉, 기존 성과표는 기보유 청산 이익(특히 KR 452260 +46,350 KRW)을 전략 성과에 포함해
+전략 자체 손익을 과대평가한 상태다.
+
+### 3.6 데이터 무결성 점검 (모의투자 혼합 여부 + USD 과대수익 원인)
+
+- `mode` 점검 결과: `live` 19,130건, `paper` 0건  
+  → **모의투자 혼합은 확인되지 않음**.
+- 다만 USD 손익에는 **체결 매칭 이상치 1건**이 존재:
+  - `CRCA` SELL(15주, $35.14, +4,612.15 USD) vs 직전 BUY(146주, $3.5499)
+  - BUY/SELL 수량 불일치(146→15) 상태에서 PnL이 계산되어, 역분할/동기화 이슈 가능성이 큼.
+
+보수적 재집계(2026-02-25~2026-02-27, USD SELL 28건):
+
+| 집계 기준 | USD 손익 | 환산 KRW (참고) | KRW 합산 참고값 |
+|-----------|----------|-----------------|-----------------|
+| 원집계 | **+4,253.70 USD** | +6,167,865 | -56,735 + 6,167,865 = **+6,111,130** |
+| 기존보유(startup-sync) 제외 | **+4,232.67 USD** | +6,137,372 | -68,965 + 6,137,372 = **+6,068,407** |
+| 수량 일치 체결만 포함 | **-358.45 USD** | -519,753 | -56,735 + (-519,753) = **-576,488** |
+| 기존보유 제외 + 수량 일치 체결만 포함 | **-379.48 USD** | -550,246 | -68,965 + (-550,246) = **-619,211** |
+
+> 가정 환율: **1 USD = 1,450 KRW** (2026-02-28 기준 참고 환율).
+> 환산 KRW 및 합산값은 비교용 보조지표이며, 회계/정산 기준값과는 분리해 해석해야 한다.
+
+결론적으로 USD 구간의 플러스 성과는 실질적으로 `CRCA` 이상치 1건 영향이 지배적이며,
+해당 거래를 무결성 필터로 제외하면 USD 성과는 손실 구간으로 전환된다.
+
+### 3.7 데이터 품질 이슈 요약
+
+- **startup-sync 중복**: BUY 76건 반복 동기화, price=0 38건 → PnL 매칭 왜곡 가능. 분리 집계는 3.5 참조.
+- **티커-거래소 드리프트**: 동일 티커가 다중 거래소에 혼재 기록 → ROOT-7 참조.
+- **FX PnL 미활성**: 스키마 존재, 운영 데이터 전부 0 → REQ-V3-007 참조.
+
+### 3.8 표준 집계 SQL (재현용)
+
+성과표 재현을 위한 기준 쿼리는 [`scripts/audit_queries.sql`](../../scripts/audit_queries.sql)에 분리되어 있다.
+
+- **Base**: 기간 + LIVE + SELL + 직전 BUY 메타 매칭
+- **Q1**: 통화 분리 손익 (KRW/USD 혼합 금지)
+- **Q2**: 기존 보유(startup-sync) 제외 성과
+- **Q3**: 수량 일치 체결만 포함 (무결성 필터)
+- **Q4**: 이상치 목록 (수량 불일치)
+
+---
+
+## 4. 수익률 저조 근본 원인 분석
+
+### ROOT-1: hard_stop_pct 기본값(-2%)이 KR 소형주 변동성 대비 과소
+
+- **현재 설정**: `stop_loss_threshold = -2.0` (`src/main.py:511`), staged exit의 `hard_stop_pct`로 전달
+- **v2 계획**: ATR 기반 동적 trailing stop (ExitPrice = PeakPrice - k × ATR)
+- **실제 동작**: staged exit는 호출되나, `atr_value`/`pred_down_prob` 등 피처가 0.0으로 공급되어 hard_stop 편향 발동 (ROOT-5 참조)
+- **증거**:
+  - 000370: 매수 8,040 → 24분 후 -2.74% 손절
+  - 033340: 매수 2,080 → 18분 후 -3.13% 손절
+  - 229000: -3.7%, -3.25%, -3.2% 반복 손절
+
+### ROOT-2: 동일 종목 반복 매매 (재진입 쿨다운 미구현)
+
+- **문제**: 손절 후 동일 종목 즉시 재매수 → 고가 재진입 → 재손절 반복
+- **최악 사례**: 종목 229000
+  | 매수가 | 매도가 | 손익 | 보유 시간 |
+  |--------|--------|------|-----------|
+  | 5,670 | 5,460 | -24,780 | 0.5h |
+  | 5,540 | 5,360 | -21,780 | 0.7h |
+  | 5,310 | 5,580 | +34,020 (승) | 0.8h |
+  | 5,620 | 5,440 | -21,420 | 1.5h |
+- **순손실**: 하루 한 종목에서 **-33,960 KRW**
+
+### ROOT-3: 미국 페니스탁/마이크로캡 무분별 진입
+
+- **문제**: $2 이하 종목에 confidence 85~90으로 진입, 오버나잇 대폭락
+- **사례**:
+  | 종목 | 손실률 | 보유시간 |
+  |------|--------|----------|
+  | ALBT | -27.7% | ~23h |
+  | SMJF | -15.9% | ~23h |
+  | KAPA | -18.2% | ~23h |
+  | CURX | -10.6% | ~23h |
+  | CELT | -8.3% | ~23h |
+
+### ROOT-4: 진화 전략 코드 생성기 문법 오류
+
+- **위치**: `src/strategies/v20260227_*_evolved.py`
+- **문제**: 중첩 `def evaluate` 정의 (들여쓰기 오류)
+- **영향**: 런타임 실패 → 기본 전략으로 폴백 → 진화 시스템 사실상 무효
+
+### ROOT-5: v2 청산 로직이 부분 통합되었으나 실효성 부족 (HIGH)
+
+- **현재 상태**: `src/main.py:500-583`에서 `evaluate_exit()` 기반 staged exit override가 동작함
+  - 상태기계(HOLDING→BE_LOCK→ARMED→EXITED) 전이 구현
+  - 4중 청산(hard stop, BE lock threat, ATR trailing, model/liquidity exit) 평가
+- **실효성 문제**:
+  - `hard_stop_pct`에 고정 `-2.0`이 기본값으로 들어가 v2 계획의 ATR 적응형 의도와 괴리
+  - `be_arm_pct`/`arm_pct`가 playbook의 `take_profit_pct`에서 기계적 파생(`* 0.4`)되어 v2 계획의 독립 파라미터 튜닝 불가
+  - `atr_value`, `pred_down_prob` 등 런타임 피처가 대부분 0.0으로 들어와 사실상 hard stop만 발동
+- **결론**: 코드 통합은 되었으나, 피처 공급과 파라미터 설정이 미비하여 v2 설계 가치가 실현되지 않는 상태
+
+### ROOT-6: SELL 손익 계산이 부분청산/수량 불일치에 취약 (CRITICAL)
+
+- **위치**: `src/main.py:1658-1663`, `src/main.py:2755-2760`
+- **문제**: PnL 계산이 실제 매도 수량(`sell_qty`)이 아닌 직전 BUY의 `buy_qty`를 사용
+  - `trade_pnl = (trade_price - buy_price) * buy_qty`
+- **영향**: 부분청산, 역분할/액분할, startup-sync 후 수량 드리프트 시 손익 과대/과소 계상
+- **실증**: CRCA 이상치(BUY 146주 → SELL 15주에서 PnL +4,612 USD) 가 이 버그와 정합
+
+### ROOT-7: BUY 매칭 키에 exchange_code 미포함 — 잠재 오매칭 리스크 (HIGH)
+
+- **위치**: `src/db.py:292-313`
+- **문제**: `get_latest_buy_trade()`가 `(stock_code, market)`만으로 매칭, `exchange_code` 미사용
+- **성격**: 현재 즉시 발생하는 확정 버그가 아닌, 동일 티커가 다중 거래소에 혼재 기록될 때 증폭되는 구조 리스크
+- **영향**: 데이터 드리프트 조건(예: CCUP/CRCA 등 다중 exchange 기록)에서 오매칭 → 손익 왜곡 가능

+
+## 5. 수익률 개선 방안
+
+### 5.1 즉시 적용 가능 (파라미터/로직 수정)
+
+| 우선순위 | 방안 | 예상 효과 | 난이도 |
+|----------|------|-----------|--------|
+| P0 | KR 손절선 확대: -2% → -4~5% 또는 ATR 기반 | 노이즈 손절 대폭 감소 | 낮음 |
+| P0 | 재진입 쿨다운: 손절 후 동일 종목 1~2시간 매수 차단 | churn & burn 패턴 제거 | 낮음 |
+| P1 | US 최소 가격 필터: $5 이하 종목 진입 차단 | 페니스탁 대폭락 방지 | 낮음 |
+| P1 | 진화 전략 코드 생성 시 syntax 검증 추가 | 진화 시스템 정상화 | 낮음 |
+
+### 5.2 구조적 개선 (아키텍처 변경)
+
+| 우선순위 | 방안 | 예상 효과 | 난이도 |
+|----------|------|-----------|--------|
+| **P0** | **SELL PnL 계산을 sell_qty 기준으로 수정 (ROOT-6)** | 손익 계상 정확도 확보, 이상치 제거 | 낮음 |
+| **P0** | **v2 staged exit에 실제 피처 공급 (atr_value, pred_down_prob) + 독립 파라미터 설정 (ROOT-5)** | v2 설계 가치 실현, 수익 보호 | 중간 |
+| P0 | BUY 매칭 키에 exchange_code 추가 (ROOT-7) | 오매칭 방지 | 낮음 |
+| P0 | 블랙아웃 복구 주문에 `log_trade()` 추가 (GAP-4) | DB/성과 리포트 정합성 | 낮음 |
+| P1 | 세션 전환 시 리스크 파라미터 동적 재로딩 (GAP-3 해소) | 세션별 최적 파라미터 적용 | 중간 |
+| P1 | session_id를 거래 로그/의사결정 로그에 명시적 전달 (GAP-1,2 해소) | 세션별 성과 분석 가능 | 낮음 |
+| P2 | 블랙아웃 복구 시 가격/세션 재검증 강화 (GAP-4 잔여) | 세션 변경 후 무효 주문 방지 | 중간 |
+
+### 5.3 권장 실행 순서
+
+```
+Phase 1 (즉시): 파라미터 조정
+  → KR 손절 확대 + 재진입 쿨다운 + US 가격 필터
+  → 예상: 가장 큰 손실 패턴 2개(노이즈 손절, 반복 매매) 즉시 제거
+
+Phase 2 (단기): 데이터 정합성 + v2 실효화
+  → SELL PnL을 sell_qty 기준으로 수정
+  → BUY 매칭 키에 exchange_code 추가
+  → 블랙아웃 복구 주문 DB 기록 추가
+  → v2 staged exit에 실제 피처(ATR, pred_down_prob) 공급 + 독립 파라미터 설정
+  → session_id 명시적 전달
+  → 예상: 손익 정확도 확보 + 수익 구간 보호 메커니즘 실효화
+
+Phase 3 (중기): v3 세션 최적화
+  → 세션 전환 훅 + 파라미터 재로딩
+  → 블랙아웃 재검증
+  → 운영 거버넌스 CI 자동화

+# 문서 재구조화 계획: 감사 → 실행 파이프라인
+
+## Context
+
+80_implementation_audit.md는 v2/v3 구현 감사와 수익률 분석을 수행했으나, 여러 차례 리뷰를 거치면서 리뷰 이력/데이터 품질 논의/SQL 쿼리 등이 혼재되어 **실행 문서로 사용하기 어려운 상태**다.
+
+목표: 이 감사 결과를 바탕으로 **티켓 생성 → 개발 설계 → 구현/리뷰 → 검증 → 실환경 테스트**까지 일관되게 진행할 수 있는 문서 체계를 만든다.
+
+## 변경 사항
+
+### 1. 80_implementation_audit.md 정리 (감사 기록 문서)
+
+**역할**: 현재 상태의 팩트 기록. "무엇이 문제인가"에만 집중.
+
+정리 내용:
+- Section 3: P&L 분석을 핵심 수치만 남기고 간결화
+  - 3.1(종합), 3.3(시장별), 3.4(통화 분리), 3.5(전략 진입분 분리), 3.6(무결성 결론) 유지
+  - 3.2 일별 손익: 주의 문구 제거, 본문으로 통합
+  - 3.7 데이터 품질: 핵심 결론만 남기고 세부 항목 제거
+  - 3.8 SQL: 별도 파일(`scripts/audit_queries.sql`)로 분리, 본문에서 참조만
+- Section 6.1, 6.2 리뷰 반영 이력: 전부 제거 (git history로 추적 가능)
+- Section 6 테스트: "재점검으로 확인" 항목을 "테스트 존재" 항목에 통합
+- 신규 Section 7: 후속 문서 링크 (85_ 참조)
+
+### 2. 85_loss_recovery_action_plan.md 신규 작성 (실행 계획 문서)
+
+**역할**: "어떻게 고칠 것인가". 티켓 생성부터 실환경 검증까지의 실행 청사진.
+
+구조:

+### 1.1 목표
+
+80_implementation_audit.md에서 식별된 7개 근본 원인(ROOT-1~7)과 5개 구현 갭(GAP-1~5)을 해소하여 실거래 손실 구간에서 탈출한다.

+
+### Phase 1: 즉시 — 손실 출혈 차단
+
+가장 큰 손실 패턴(노이즈 손절, 반복 매매, 페니스탁)을 즉시 제거한다.
+
+---
+
+#### ACT-01: KR 손절선 ATR 기반 동적 확대
+
+- **ROOT 참조**: ROOT-1 (hard_stop_pct -2%가 KR 소형주 변동성 대비 과소)
+- **Gitea 이슈**: feat: KR 손절선 ATR 기반 동적 확대 (-2% → ATR 적응형)
+- **Gitea 이슈 번호**: #318
+- **변경 대상 파일**: `src/main.py`, `src/strategy/exit_rules.py`, `src/config.py`
+- **현재 동작**: `hard_stop_pct = -2.0` 고정값으로 모든 시장에 동일 적용
+- **목표 동작**: KR 시장은 ATR(14) 기반 동적 손절선 적용. 최소 -2%, 최대 -7%, 기본값은 `k * ATR / entry_price * 100` (k=2.0)
+- **수용 기준**:
+  - ATR 값이 존재할 때 동적 손절선이 계산됨
+  - ATR 미제공 시 기존 -2% 폴백
+  - KR 이외 시장은 기존 동작 유지
+- **테스트 계획**:
+  - 단위: ATR 기반 손절선 계산 로직 테스트 (경계값: ATR=0, ATR=극단값)
+  - 통합: 백테스트 파이프라인에서 KR 종목 손절 빈도 비교
+- **의존성**: 없음
+
+---
+
+#### ACT-02: 손절 후 동일 종목 재진입 쿨다운
+
+- **ROOT 참조**: ROOT-2 (동일 종목 반복 매매)
+- **Gitea 이슈**: feat: 손절 후 동일 종목 재진입 쿨다운 (1~2시간)
+- **Gitea 이슈 번호**: #319
+- **변경 대상 파일**: `src/main.py`, `src/config.py`
+- **현재 동작**: 손절 후 동일 종목 즉시 재매수 가능
+- **목표 동작**: 손절(SELL with pnl < 0) 후 동일 종목은 `COOLDOWN_MINUTES` (기본 120분) 동안 매수 차단
+- **수용 기준**:
+  - 손절 기록이 있는 종목에 대해 쿨다운 시간 내 BUY 시도 시 거부
+  - 쿨다운 경과 후 정상 진입 허용

+모든 티켓은 아래 4단계를 순서대로 통과해야 한다.
+
+1. `Implemented`: 코드/문서 변경 완료
+2. `Integrated`: 호출 경로/파이프라인 연결 완료
+3. `Observed`: 런타임/실행 증적 확보 완료
+4. `Accepted`: 정적 Verifier + Runtime Verifier 승인 완료
+
+강제 규칙:
+- 단계 점프 금지 (예: Implemented -> Accepted 금지)
+- `Observed` 전에는 완료 선언 금지
+- `Accepted` 전에는 머지 금지
