+# 실전 전환 체크리스트
+
+모의 거래(paper)에서 실전(live)으로 전환하기 전에 아래 항목을 **순서대로** 모두 확인하세요.
+
+---
+
+## 1. 사전 조건
+
+### 1-1. KIS OpenAPI 실전 계좌 준비
+- [ ] 한국투자증권 계좌 개설 완료 (일반 위탁 계좌)
+- [ ] OpenAPI 실전 사용 신청 (KIS 홈페이지 → Open API → 서비스 신청)
+- [ ] 실전용 APP_KEY / APP_SECRET 발급 완료
+- [ ] KIS_ACCOUNT_NO 형식 확인: `XXXXXXXX-XX` (8자리-2자리)
+
+### 1-2. 리스크 파라미터 검토
+- [ ] `CIRCUIT_BREAKER_PCT` 확인: 기본값 -3.0% (더 엄격하게 조정 권장)
+- [ ] `FAT_FINGER_PCT` 확인: 기본값 30.0% (1회 주문 최대 잔고 대비 %)
+- [ ] `CONFIDENCE_THRESHOLD` 확인: BEARISH ≥ 90, NEUTRAL ≥ 80, BULLISH ≥ 75
+- [ ] 초기 투자금 결정 및 해외 주식 운용 한도 설정
+
+### 1-3. 시스템 요건
+- [ ] 커버리지 80% 이상 유지 확인: `pytest --cov=src`
+- [ ] 타입 체크 통과: `mypy src/ --strict`
+- [ ] Lint 통과: `ruff check src/ tests/`
+
+---
+
+## 2. 환경 설정
+
+### 2-1. `.env` 파일 수정
+
+```bash
+# 1. KIS 실전 URL로 변경 (모의: openapivts 포트 29443)
+KIS_BASE_URL=https://openapi.koreainvestment.com:9443
+
+# 2. 실전 APP_KEY / APP_SECRET으로 교체
+KIS_APP_KEY=<실전_APP_KEY>
+KIS_APP_SECRET=<실전_APP_SECRET>
+KIS_ACCOUNT_NO=<실전_계좌번호>
+
+# 3. 모드를 live로 변경
+MODE=live
+
+# 4. PAPER_OVERSEAS_CASH 비활성화 (live 모드에선 무시되지만 명시적으로 0 설정)
+PAPER_OVERSEAS_CASH=0
+```
+
+> ⚠️ `KIS_BASE_URL` 포트 주의:
+> - **모의(VTS)**: `https://openapivts.koreainvestment.com:29443`
+> - **실전**: `https://openapi.koreainvestment.com:9443`
+
+### 2-2. TR_ID 자동 분기 확인
+
+아래 TR_ID는 `MODE` 값에 따라 코드에서 **자동으로 선택**됩니다.
+별도 설정 불필요하나, 문제 발생 시 아래 표를 참조하세요.
+
+| 구분 | 모의 TR_ID | 실전 TR_ID |

+
+> **출처**: `docs/한국투자증권_오픈API_전체문서_20260221_030000.xlsx` (공식 문서 기준)
+
+---
+
+## 3. 최종 확인
+
+### 3-1. 실전 시작 전 점검
+- [ ] DB 백업 완료: `data/trade_logs.db` → `data/backups/`
+- [ ] Telegram 알림 설정 확인 (실전에서는 알림이 더욱 중요)
+- [ ] 소액으로 첫 거래 진행 후 TR_ID/계좌 정상 동작 확인
+
+### 3-2. 실행 명령
+
+```bash
+# 실전 모드로 실행
+python -m src.main --mode=live
+
+# 대시보드 함께 실행 (별도 터미널에서 모니터링)
+python -m src.main --mode=live --dashboard
+```
+
+### 3-3. 실전 시작 직후 확인 사항
+- [ ] 로그에 `MODE=live` 출력 확인
+- [ ] 첫 잔고 조회 성공 (ConnectionError 없음)
+- [ ] Telegram 알림 수신 확인 ("System started")
+- [ ] 첫 주문 후 KIS 앱에서 체결 내역 확인
+
+---
+
+## 4. 비상 정지 방법
+
+### 즉각 정지
+```bash
+# 터미널에서 Ctrl+C (정상 종료 트리거)
+# 또는 Telegram 봇 명령:
+/stop
+```
+
+### Circuit Breaker 발동 시
+- CB가 발동되면 자동으로 거래 중단 및 Telegram 알림 전송
+- CB 임계값: `CIRCUIT_BREAKER_PCT` (기본 -3.0%)
+- **임계값은 엄격하게만 조정 가능** (더 낮은 음수 값으로만 변경)
+
+---
+
+## 5. 롤백 절차
+
+실전 전환 후 문제 발생 시:
+
+```bash
+# 1. 즉시 .env에서 MODE=paper로 복원
+# 2. 재시작
+python -m src.main --mode=paper
+
+# 3. DB에서 최근 거래 확인
+sqlite3 data/trade_logs.db "SELECT * FROM trades ORDER BY id DESC LIMIT 20;"

+# 문서 검증 시스템
+
+본 문서는 문서 간 허위 내용, 수치 충돌, 구현 불가능 지시를 사전에 제거하기 위한 검증 규칙이다.
+
+## 검증 목표
+
+- 단일 진실원장 기준으로 모든 지시서의 수치/규칙 정합성 보장
+- 설계 문장과 코드 작업 지시 간 추적성 보장
+- 테스트 미정의 상태에서 구현 착수 금지
+
+## 불일치 유형 정의
+
+- `RULE-DOC-001`: 정의되지 않은 요구사항 ID 사용
+- `RULE-DOC-002`: 동일 요구사항 ID에 상충되는 값(예: 슬리피지 수치) 기술
+- `RULE-DOC-003`: 시간대 미표기 또는 KST/UTC 혼용 지시
+- `RULE-DOC-004`: 주문 정책과 리스크 정책 충돌(예: 저유동 세션 시장가 허용)
+- `RULE-DOC-005`: 구현 태스크에 테스트 ID 미연결
+- `RULE-DOC-006`: 문서 라우팅 링크 깨짐
+
+## 검증 파이프라인
+
+1. 정적 검사 (자동)
+- 대상: `docs/ouroboros/*.md`
+- 검사: 메타데이터, 링크 유효성, ID 정의/참조 일치, REQ-추적성 매핑
+- 도구: `scripts/validate_ouroboros_docs.py`
+
+2. 추적성 검사 (자동 + 수동)
+- 자동: `REQ-*`가 최소 1개 `TASK-*`와 1개 `TEST-*`에 연결되었는지 확인
+- 수동: 정책 충돌 후보를 PR 체크리스트로 검토
+
+3. 도메인 무결성 검사 (수동)
+- KIS 점검시간 회피, 주문 유형 강제, Kill Switch 순서, 환율 정책이 동시에 존재하는지 점검
+- 백테스트 체결가가 보수 가정인지 점검
+
+## 변경 통제 규칙
+
+- `REQ-*` 추가/수정 시 반드시 `01_requirements_registry.md` 먼저 변경
+- `TASK-*` 수정 시 반드시 `40_acceptance_and_test_plan.md`의 대응 테스트를 동시 수정
+- 충돌 발생 시 우선순위: `requirements_registry > phase execution > code work order`
+
+적용 룰셋:
+- `RULE-DOC-001` `RULE-DOC-002` `RULE-DOC-003` `RULE-DOC-004` `RULE-DOC-005` `RULE-DOC-006`
+
+## PR 게이트
+
+- `python3 scripts/validate_ouroboros_docs.py` 성공
+- 신규/변경 `REQ-*`가 테스트 기준(`TEST-*`)과 연결됨

+5. Runtime Verifier가 발행한 `RUNTIME-VERIFY` 이슈는 Main Agent 확인 전 클로즈 금지.
+
+## 4) 즉시 생성 권장 티켓 (초기 백로그)
+

+
+## 5) 운영 체크포인트
+
+- 스프린트 계획 시 `P0` 시나리오 100% 테스트 통과를 출발 조건으로 둔다.
+- 배포 승인 시 `SCN-FAIL-*`, `SCN-OPS-*` 관련 `TEST-ACC-*`를 우선 확인한다.
+- 정책 변경 PR은 반드시 원장(`01_requirements_registry.md`) 선수정 후 진행한다.

+Control checks:
+- PM/TPM/Dev 3자 종료 확인
+- Runtime Verifier가 운영 모니터링 이슈 상태(신규/진행/해결)를 리포트
+- Main Agent 최종 승인(DCP-04)
+- 산출물: 릴리즈 노트 + 후속 액션 목록
+
+## Replan Protocol (Dev -> TPM)
+
+- 트리거:
+  - 구현 불가능(기술적 제약/외부 API 제약)
+  - 예상 대비 개발 리소스 과다(공수/인력/의존성 급증)
+- 절차:
+  1) Dev Agent가 `REPLAN-REQUEST` 발행(영향 REQ/TASK, 원인, 대안, 추가 공수 포함)
+  2) TPM Agent가 1차 심사(범위 축소/단계 분할/요구사항 조정안)
+  3) Verifier/PM 의견 수렴 후 Main Agent 승인으로 재계획 확정
+- 규칙:
+  - Main Agent 승인 없는 재계획은 실행 금지
+  - 재계획 반영 시 문서(`REQ/TASK/TEST`) 동시 갱신 필수
+
+TPM 티켓 운영 규칙:
+- TPM은 합의된 변경을 이슈로 등록하고 우선순위(`P0/P1/P2`)를 지정한다.
+- PR 본문에는 TPM이 지정한 우선순위와 범위가 그대로 반영되어야 한다.
+- 우선순위 변경은 TPM 제안 + Main Agent 승인으로만 가능하다.
+- PM/TPM/Dev/Reviewer/Verifier/Runtime Verifier는 주요 의사결정 시점마다 PR 코멘트를 남겨 결정 근거를 추적 가능 상태로 유지한다.
+- PM/TPM/Dev/Reviewer/Verifier/Runtime Verifier는 이슈/PR/코멘트 조작 전에 `docs/commands.md`와 `docs/workflow.md`의 Gitea 트러블슈팅 섹션을 선참조해야 한다.
+- 저장소 협업에서 GitHub CLI(`gh`) 사용은 금지하며, Gitea 작업은 `tea`(필요 시 문서화된 API fallback)만 허용한다.
+
+브랜치 운영 규칙:
+- TPM은 각 티켓에 대해 `ticket temp branch -> program feature branch` PR 경로를 지정한다.
+- 티켓 머지 대상은 항상 program feature branch이며, `main`은 최종 통합 단계에서만 사용한다.
+
+## Runtime Verification Protocol
+
+- Runtime Verifier는 테스트 통과 이후 실제 동작(스테이징/실운영)을 모니터링한다.
+- 이상 동작/현상 발견 시 즉시 이슈 발행:
+  - 제목 규칙: `[RUNTIME-VERIFY][SCN-*] ...`
+  - 본문 필수: 재현조건, 관측 로그, 영향 범위, 임시 완화책, 관련 `REQ/TASK/TEST`
+- 이슈 클로즈 규칙:
+  - Dev 수정 완료 + Verifier 재검증 통과 + Runtime Verifier 재관측 정상
+  - 최종 클로즈 승인자는 Main Agent
+- 개발 완료 필수 절차:
+  - 시스템 실제 구동(스테이징/로컬 실운영 모드) 실행
+  - 모니터링 체크리스트(핵심 경보/주문 경로/예외 로그) 수행
+  - 결과를 티켓/PR 코멘트에 증적으로 첨부하지 않으면 완료로 간주하지 않음
+  - 세션별 필수 관측 포인트(`NXT`, `US_PRE`, `US_DAY`, `US_AFTER` 등) 중 미관측 항목은 `NOT_OBSERVED`로 기록
+  - `NOT_OBSERVED` 존재 시 승인 금지 + Runtime 이슈 발행
+
+## Server Reflection Rule
+
+- `ticket temp branch -> program feature branch` 머지는 검증 승인 후 자동/수동 진행 가능하다.
+- `program feature branch -> main` 머지는 사용자 명시 승인 시에만 허용한다.
+- Main 병합 시 Main Agent가 승인 근거를 PR 코멘트에 기록한다.

+- 모의투자 실행 시 MLECW, KNRX, NBY, SNSE 등 만료/정지된 종목에 대해
+  `모의투자 잔고내역이 없습니다` 오류가 매 사이클 반복됨
+
+**근본 원인:**
+1. `ovrs_cblc_qty` (해외잔고수량, 총 보유) vs `ord_psbl_qty` (주문가능수량, 실제 매도 가능)
+   - 기존 코드: `ovrs_cblc_qty` 우선 사용 → 만료 Warrant가 `ovrs_cblc_qty=289456`이지만 실제 `ord_psbl_qty=0`
+   - startup sync / build_overseas_symbol_universe가 이 종목들을 포지션으로 기록
+2. SELL 실패 시 DB 포지션이 닫히지 않아 다음 사이클에서도 재시도 (무한 반복)
+
+**구현 내용:**
+
+1. `src/main.py` — `_extract_held_codes_from_balance`, `_extract_held_qty_from_balance`
+   - 해외 잔고 필드 우선순위 변경: `ord_psbl_qty` → `ovrs_cblc_qty` → `hldg_qty` (fallback 유지)
+   - KIS 공식 문서(VTTS3012R) 기준: `ord_psbl_qty`가 실제 매도 가능 수량
+
+2. `src/main.py` — `trading_cycle` ghost-close 처리
+   - 해외 SELL이 `잔고내역이 없습니다`로 실패 시 DB 포지션을 `[ghost-close]` SELL로 종료
+   - exchange code 불일치 등 예외 상황에서 무한 반복 방지

+
+1. `docs/commands.md`의 `tea CLI` 실패 사례/해결 패턴 확인
+2. 본 문서의 `Gitea CLI Formatting Troubleshooting` 확인
+3. 명령 실행 전 `gh`(GitHub CLI) 사용 금지 확인

+- Ticket-level development happens only on **ticket temp branches** cut from the program feature branch.
+- Ticket PR merges into program feature branch are allowed after verifier approval.
+- Until final user sign-off, `main` merge is prohibited.

+[The Ouroboros] 운영/전략 계획서 v2
+작성일: 2026-02-26
+상태: 코드 구현 전 설계안(전략/검증 중심)
+
+==================================================
+0) 목적
+==================================================
+고정 익절(+3%) 중심 로직에서 벗어나, 다음을 만족하는 실전형 청산 체계로 전환한다.
+- 수익 구간 보호 (손익 역전 방지)
+- 변동성 적응형 청산
+- 예측 모델의 확률 신호를 보조적으로 결합
+- 과적합 방지를 최우선으로 한 검증 프레임워크
+
+==================================================
+1) 핵심 설계 원칙
+==================================================
+1. 예측 성능과 전략 성능을 분리 평가
+- 예측 성능: PR-AUC, Brier, Calibration
+- 전략 성능: Net PnL, Sharpe, MDD, Profit Factor, Turnover
+
+2. 시계열 검증 규율 강제
+- Walk-forward 분할
+- Purge/Embargo 적용
+- Random split 금지
+
+3. 실거래 리얼리즘 우선
+- 거래비용/슬리피지/체결실패 반영 없는 백테스트 결과는 채택 금지
+
+==================================================
+2) 매도 상태기계 (State Machine)
+==================================================
+상태:
+- HOLDING
+- BE_LOCK
+- ARMED
+- EXITED
+
+정의:
+- HOLDING: 일반 보유 상태
+- BE_LOCK: 일정 수익권 진입 시 손절선을 본전(또는 비용 반영 본전)으로 상향
+- ARMED: 추세 추적(피크 추적) 기반 청산 준비 상태
+- EXITED: 청산 완료
+
+전이 규칙(개념):
+- HOLDING -> BE_LOCK: unrealized_pnl_pct >= be_arm_pct
+- BE_LOCK -> ARMED: unrealized_pnl_pct >= arm_pct
+- ARMED -> EXITED: 아래 조건 중 하나 충족
+  1) hard stop 도달
+  2) trailing stop 도달 (peak 대비 하락)
+  3) 모델 하락확률 + 유동성 약화 조건 충족
+
+상태 전이 구현 규칙(필수):
+- 매 틱/바 평가 시 "현재 조건이 허용하는 최상위 상태"로 즉시 승격
+- 순차 if-else로 인한 전이 누락 금지 (예: 갭으로 BE_LOCK/ARMED 동시 충족)
+- EXITED 조건은 모든 상태보다 우선 평가
+- 상태 전이 로그에 이전/이후 상태, 전이 사유, 기준 가격/수익률 기록
+
+==================================================
+3) 청산 로직 구성 (4중 안전장치)
+==================================================
+A. Hard Stop
+- 계좌/포지션 보호용 절대 하한
+- 항상 활성화
+
+B. Dynamic Stop (Break-even Lock)
+- BE_LOCK 진입 시 손절선을 본전 이상으로 상향
+- "수익 포지션이 손실로 반전"되는 구조적 리스크 차단
+
+C. ATR 기반 Trailing Stop
+- 고정 trail_pct 대신 변동성 적응형 사용
+- 예시: ExitPrice = PeakPrice - (k * ATR)
+
+D. 모델 확률 신호
+- 하락전환 확률(pred_prob)이 임계값 이상일 때 청산 가중
+- 단독 트리거가 아닌 trailing/리스크 룰 보조 트리거로 사용
+
+==================================================
+4) 라벨링 체계 (Triple Barrier)
+==================================================
+목표:
+고정 H-window 라벨 편향을 줄이고, 금융 시계열의 경로 의존성을 반영한다.
+
+라벨 정의:
+- Upper barrier (익절)
+- Lower barrier (손절)
+- Time barrier (만기)
+
+규칙:
+- 세 장벽 중 "먼저 터치한 장벽"으로 라벨 확정
+- 라벨은 entry 시점 이후 데이터만 사용해 생성
+- 피처 생성 구간과 라벨 구간을 엄격 분리해 look-ahead bias 방지
+
+==================================================
+5) 검증 프레임워크
+==================================================
+5.1 분할 방식
+- Fold 단위 Walk-forward
+- Purge/Embargo로 인접 샘플 누수 차단
+
+5.2 비교군(Baseline) 구조
+- B0: 기존 고정 손절/익절
+- B1: 모델 없는 trailing only
+- M1: trailing + 모델 확률 결합
+
+5.3 채택 기준
+- M1이 B0/B1 대비 OOS(Out-of-sample)에서 일관된 우위
+- 단일 구간 성과가 아닌 fold 분포 기준으로 판단
+
+==================================================
+6) 실행 아키텍처 원칙
+==================================================
+1. 저지연 실행 경로
+- 실시간 청산 판단은 경량 엔진(룰/GBDT) 담당
+- LLM은 레짐 판단/비중 조절/상위 의사결정 보조
+
+2. 체결 현실 반영
+- 세션 유동성에 따른 슬리피지 페널티 차등 적용
+- 미체결/재호가/재접수 시나리오를 백테스트에 반영
+
+==================================================
+7) 운영 리스크 관리
+==================================================
+승격 단계:
+- Offline backtest -> Paper shadow -> Small-capital live
+
+중단(Kill Switch):
+- rolling Sharpe 악화
+- MDD 한도 초과
+- 체결 실패율/슬리피지 급등
+
+Kill Switch 실행 순서(원자적):
+1) 모든 신규 주문 차단 플래그 ON
+2) 모든 미체결 주문 취소 요청
+3) 취소 결과 재조회(실패 건 재시도)
+4) 포지션 리스크 재계산 후 강제 축소/청산 판단
+5) 상태/로그 스냅샷 저장 및 운영 경보 발송
+
+원칙:
+- 모델이 실패해도 hard stop 기반 보수 모드로 즉시 디그레이드 가능해야 함
+
+==================================================
+8) 고정 파라미터(초기안)
+==================================================
+(15분봉 단기 스윙 기준 제안)
+- KR: be_arm_pct=1.2, arm_pct=2.8, atr_period=14, atr_multiplier_k=2.2,
+      time_barrier_bars=26, p_thresh=0.62
+- US: be_arm_pct=1.0, arm_pct=2.4, atr_period=14, atr_multiplier_k=2.0,
+      time_barrier_bars=32, p_thresh=0.60
+
+민감도 범위(초기 탐색):
+- be_arm_pct: KR 0.9~1.8 / US 0.7~1.5
+- arm_pct: KR 2.2~3.8 / US 1.8~3.2
+- atr_multiplier_k: KR 1.8~2.8 / US 1.6~2.4
+- time_barrier_bars: KR 20~36 / US 24~48
+- p_thresh: 0.55~0.70
+
+==================================================
+9) 구현 전 체크리스트
+==================================================
+- 파라미터 튜닝 시 nested leakage 방지
+- 수수료/세금/슬리피지 전부 반영 여부 확인
+- 세션/타임존/DST 처리 일관성 확인
+- 모델 버전/설정 해시/실험 로그 재현성 확보
+
+끝.

+[The Ouroboros] 운영확장 v3
+작성일: 2026-02-26
+상태: v2 확장판 / 야간·프리마켓 포함 글로벌 세션 운영 설계안
+
+==================================================
+0) 목적
+==================================================
+"24시간 무중단 자산 증식" 비전을 위해 거래 세션 범위를 KR 정규장 중심에서
+NXT/미국 확장 세션까지 확대한다. 핵심은 다음 3가지다.
+- 세션 인지형 의사결정
+- 세션별 리스크/비용 차등 적용
+- 시간장벽의 현실적 재정의
+
+==================================================
+1) 세션 모델 (Session-aware Engine)
+==================================================
+KR 세션:
+- NXT_PRE   : 08:00 ~ 08:50 (KST)
+- KRX_REG   : 09:00 ~ 15:30 (KST)
+- NXT_AFTER : 15:30 ~ 20:00 (KST)
+
+US 세션(KST 관점 운영):
+- US_DAY    : 10:00 ~ 18:00
+- US_PRE    : 18:00 ~ 23:30
+- US_REG    : 23:30 ~ 06:00
+- US_AFTER  : 06:00 ~ 07:00
+
+원칙:
+- 모든 피처/신호/주문/로그에 session_id를 명시적으로 포함
+- 세션 전환 시 상태 업데이트 및 리스크 파라미터 재로딩
+
+==================================================
+2) 캘린더/휴장/DST 고정 소스
+==================================================
+KR:
+- 기본: pykrx 또는 FinanceDataReader (KRX 기준)
+- 예외: 연휴/임시 휴장/NXT 특이 운영은 KIS 공지 기반 보완
+
+US:
+- pandas_market_calendars (NYSE 기준)
+- 2026 DST:
+  - 시작: 2026-03-08
+  - 종료: 2026-11-01
+
+정합성 규칙:
+- 스케줄 충돌 시 "거래소 캘린더 > 로컬 추정" 우선
+- 시장 상태(open/close/half-day)는 주문 엔진 진입 전 최종 검증
+
+KIS 점검시간 회피 정책(필수):
+- 브로커 점검/장애 블랙아웃 윈도우는 운영 설정으로 별도 관리
+- 블랙아웃 구간에는 신규 주문 전송 금지, 취소/정정도 정책적으로 제한
+- 신호는 유지하되 주문 의도는 Queue에 적재, 복구 후 유효성 재검증 뒤 실행
+- 복구 직후에는 잔고/미체결/체결내역을 우선 동기화한 뒤 주문 엔진 재가동
+
+==================================================
+3) 시간장벽 재정의
+==================================================
+v2의 time_barrier_bars 고정값을 v3에서 다음으로 확장:
+- max_holding_minutes (시장별 기본 만기)
+- 봉 개수는 세션 길이/간격으로 동적 계산
+
+기본값:
+- KR: max_holding_minutes = 2160 (약 3거래일, NXT 포함 관점)
+- US: max_holding_minutes = 4320 (약 72시간)
+
+운영 주의:
+- 고정 "일중 청산"보다 "포지션 유지 시간" 기준 만기 적용
+- 세션 종료 강제청산 규칙과 충돌 시 우선순위 명시 필요
+
+==================================================
+4) 세션별 비용/슬리피지 모델 (보수적)
+==================================================
+KRX_REG:
+- 슬리피지: 2~3틱 (약 0.05%)
+- 수수료+세금: 0.20% ~ 0.23%
+
+NXT_AFTER:
+- 슬리피지: 5~8틱 (약 0.15%)
+- 수수료+세금: 0.20% ~ 0.23%
+
+US_REG:
+- 슬리피지: 2~3틱 (약 0.03%)
+- 수수료+기타 비용: 0.07% ~ 0.15%
+
+US_PRE / US_DAY:
+- 슬리피지: 10틱+ (약 0.3% ~ 0.5%)
+- 수수료+기타 비용: 0.07% ~ 0.15%
+
+원칙:
+- 백테스트 체결가는 세션별 보수 가정 적용
+- 저유동 세션은 자동 보수 모드(p_thresh 상향, atr_k 상향) 권장
+- 백테스트 체결가 기본은 "불리한 방향 체결" 가정 (단순 close 체결 금지)
+
+세션별 주문 유형 강제(필수):
+- KRX_REG / US_REG: 지정가 우선, 시장가 제한적 허용
+- NXT_AFTER / US_PRE / US_DAY / US_AFTER: 시장가 금지
+- 저유동 세션은 최우선 지정가 또는 IOC/FOK(가격 보호 한도 포함)만 허용
+- 주문 실패 시 재호가 간격/횟수 상한을 두고, 초과 시 주문 철회
+
+==================================================
+5) 포지션/잔고 통합 규칙 (KIS 특성 반영)
+==================================================
+문제:
+- KRX/NXT 잔고 조회가 venue 단위로 분리되거나 반영 지연 가능
+
+규칙:
+- 종목 식별은 동일 종목코드(또는 ISIN) 기준 통합 포지션으로 관리
+- 다만 주문 가능 수량은 venue별 API 응답을 최종 기준으로 사용
+- 매도 가능 수량 검증은 주문 직전 재조회로 확정
+
+==================================================
+6) 마감 강제청산/오버나잇 예외 규칙
+==================================================
+기본 원칙:
+- 모든 포지션에 대해 세션 종료 10분 전 REDUCE_ALL 검토
+
+오버나잇 예외 허용 (모두 충족 시):
+1) ARMED 상태 (예: +2.8% 이상)
+2) 모델 하락확률 < 0.30
+3) 포트폴리오 현금 비중 >= 50%
+
+갭 리스크 통제:
+- 다음 개장 시 hard stop를 시가 기준으로 재산정
+- 조건 위반 시 즉시 청산 우선
+
+Kill Switch 연동:
+- MDD/실패율 임계치 초과 시 "미체결 전량 취소 -> 신규 주문 차단 -> 리스크 축소" 순서 강제
+
+==================================================
+7) 데이터 저장/용량 정책
+==================================================
+핵심 테이블(계획):
+- feature_snapshots
+- position_states
+- model_predictions
+
+저장 규칙:
+- feature_hash 기반 중복 제거
+- 가격 변화가 작아도 session_id 변경 시 강제 스냅샷
+- 월 단위 DB 로테이션 권장 (예: trading_YYYY_MM.db)
+
+==================================================
+8) 환율/정산 리스크 정책 (US 필수)
+==================================================
+원칙:
+- USD 노출은 전략 손익과 별도로 환율 손익을 분리 추적
+- 원화 주문 서비스 사용 시 가환율 체결/익일 정산 리스크를 예수금 규칙에 반영
+
+운영 규칙:
+- 환전 시점 정책(사전 환전/수시 환전)을 고정하고 로그에 기록
+- 최소 USD 버퍼와 KRW 버퍼를 각각 설정해 주문 가능금 부족 리스크 완화
+- 환율 급변 구간에는 포지션 한도 축소 또는 신규 진입 제한
+
+==================================================
+9) v3 실험 매트릭스 (우선 3선)
+==================================================
+EXP-KR-01:
+- 시장: KR
+- 포커스: NXT 야간 특화
+- 제안: time barrier 확장(예: 48 bars 상당), p_thresh 상향(0.65)
+
+EXP-US-01:
+- 시장: US
+- 포커스: 21h 준연속 운용
+- 제안: time barrier 확장(예: 80 bars 상당), atr_k 상향(2.5)
+
+EXP-HYB-01:
+- 시장: Global
+- 포커스: KR 낮 + US 밤 연계
+- 제안: 레짐 기반 자산배분 자동조절
+
+==================================================
+10) 코드 착수 전 최종 확정 체크
+==================================================
+1) 세션별 공식 캘린더 소스/우선순위
+2) 세션별 슬리피지/비용 테이블 수치
+3) 시장별 max_holding_minutes
+4) 마감 강제청산 예외 조건 임계값
+5) 블랙아웃(점검/장애) 시간대와 주문 큐 처리 규칙
+6) 세션별 허용 주문 유형(시장가 허용 범위 포함)
+7) 환전/정산 정책 및 통화 버퍼 임계값
+
+모든 항목 확정 후 Step 1 구현(코드)로 이동.
+
+끝.

+# Issue #271 Workflow Run Log
+
+## 2026-02-26
+
+### Step 1: Gitea issue creation
+- Attempt 1: Succeeded, but formatting degraded
+  - Command style: `tea issues create -t ... -d "...\n..."`
+  - Symptom: Issue body rendered literal `\n` text in web UI instead of line breaks
+- Root cause
+  - `tea` does not provide `--description-file`
+  - Shell-escaped `\n` inside double quotes is passed as backslash+n text
+- Resolution
+  - Build body with heredoc and pass as variable (`-d "$ISSUE_BODY"`)
+
+### Step 2: PR description creation
+- Attempt 1: Succeeded, but same newline rendering risk detected
+- Resolution
+  - Same heredoc variable pattern applied for PR body (`--description "$PR_BODY"`)
+
+### Preventive Action
+- `docs/workflow.md` updated with "Gitea CLI Formatting Troubleshooting" section
+- Standard command templates added for issues and PRs
+
+### Reusable Safe Template
+```bash
+ISSUE_BODY=$(cat <<'EOF'
+## Summary
+- item A
+- item B
+
+## Scope
+- docs only
+EOF
+)
+
+tea issues create -t "title" -d "$ISSUE_BODY"
+```
