+
+## 3) 티켓 생성 규칙 (Implementable)
+
+1. 모든 이슈는 `taxonomy + scenario_id`를 제목에 포함한다.  
+   예: `[EXEC-POLICY][SCN-FAIL-001] blackout 주문 차단 누락`
+2. 본문 필수 항목: 재현절차, 기대결과, 실제결과, 영향범위, 롤백/완화책.
+3. 본문에 최소 1개 `REQ-*`, 1개 `TASK-*`, 1개 `TEST-*`를 명시한다.
+4. 우선순위 기준:
+- P0: 실주문 위험, Kill Switch, 블랙아웃/시장가 정책, 추적성 게이트 실패
+- P1: 손익 왜곡 가능성(체결/FX/시간대), 운영 리스크 증가
+- P2: 보고서/관측성 품질 이슈(거래 안전성 영향 없음)
+5. Runtime Verifier가 발행한 `RUNTIME-VERIFY` 이슈는 Main Agent 확인 전 클로즈 금지.
+
+## 4) 즉시 생성 권장 티켓 (초기 백로그)
+
+- `TKT-P0-001`: `[EXEC-POLICY][SCN-FAIL-001]` 블랙아웃 차단 + 큐적재 + 복구 재검증 e2e 점검 (`REQ-V3-003`,`REQ-V3-004`)
+- `TKT-P0-002`: `[RISK-EMERGENCY][SCN-FAIL-003]` Kill Switch 순서 강제 검증 자동화 (`REQ-V2-008`)
+- `TKT-P0-003`: `[OPS-GOVERNANCE][SCN-OPS-004]` REQ/TASK/TEST 누락 시 PR 차단 게이트 상시 점검 (`REQ-OPS-003`)
+- `TKT-P1-001`: `[FX-ACCOUNTING][SCN-FAIL-004]` FX 버퍼 위반 시 진입 제한 회귀 케이스 보강 (`REQ-V3-007`)
+- `TKT-P1-002`: `[BACKTEST-MODEL][SCN-HAPPY-004]` 비용/슬리피지 미설정 백테스트 거부 UX 명확화 (`REQ-V2-007`)
+- `TKT-P0-004`: `[RUNTIME-VERIFY][SCN-OPS-005]` 배포 후 런타임 이상 탐지/재현/클로즈 판정 절차 자동화
+
+## 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.

+목적:
+- PM 시나리오가 구현 가능한 단위로 분해되고, 개발/검증이 동일 ID 체계(`REQ-*`, `TASK-*`, `TEST-*`)로 닫히도록 강제한다.
+- 각 단계는 Entry/Exit gate를 통과해야 다음 단계로 이동 가능하다.
+- 주요 의사결정 포인트마다 Main Agent의 승인/의견 확인을 강제한다.
+
+## Team Roles
+
+- Main Agent: 최종 취합/우선순위/승인 게이트 오너
+- PM Agent: 시나리오/요구사항/티켓 관리
+- TPM Agent: PM-Dev-검증 간 구현 가능성/달성률 통제, 티켓 등록 및 구현 우선순위 지정 오너
+- Dev Agent: 구현 수행, 블로커 발생 시 재계획 요청
+- Verifier Agent: 문서/코드/테스트 산출물 검증

+- 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.
+
+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
+
+## 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.

+- 구현 진행 중 떠오른 신규 구현 아이디어를 계획 반영 전 임시 저장한다.
+- 본 문서는 사용자 검토 후 다음 계획 포함 여부를 결정하기 위한 검토 큐다.

+운영 규칙:
+- 각 아이디어는 `IDEA-*` 식별자를 사용한다.
+- 필수 필드: 배경, 기대효과, 리스크, 후속 티켓 후보.
+- 상태는 `proposed`, `under-review`, `accepted`, `rejected` 중 하나를 사용한다.

+## 아이디어 목록
+
+- `IDEA-001` (status: proposed)
+  - 제목: Kill-Switch 전역 상태를 프로세스 단일 전역에서 시장/세션 단위 상태로 분리
+  - 배경: 현재는 전역 block 플래그 기반이라 시장별 분리 제어가 제한될 수 있음
+  - 기대효과: KR/US 병행 운용 시 한 시장 장애가 다른 시장 주문을 불필요하게 막는 리스크 축소
+  - 리스크: 상태 동기화 복잡도 증가, 테스트 케이스 확장 필요
+  - 후속 티켓 후보: `TKT-P1-KS-SCOPE-SPLIT`
+
+- `IDEA-002` (status: proposed)
+  - 제목: Exit Engine 입력 계약(ATR/peak/model_prob/liquidity) 표준 DTO를 데이터 파이프라인에 고정
+  - 배경: 현재 ATR/모델확률 일부가 fallback 기반이라 운영 일관성이 약함
+  - 기대효과: 백테스트-실거래 입력 동형성 강화, 회귀 분석 용이
+  - 리스크: 기존 스캐너/시나리오 엔진 연동 작업량 증가
+  - 후속 티켓 후보: `TKT-P1-EXIT-CONTRACT`
+
+- `IDEA-003` (status: proposed)
+  - 제목: Runtime Verifier 자동 이슈 생성기(로그 패턴 -> 이슈 템플릿 자동화)
+  - 배경: 런타임 이상 리포트가 수동 작성 중심이라 누락 가능성 존재
+  - 기대효과: 이상 탐지 후 이슈 등록 리드타임 단축, 증적 표준화
+  - 리스크: 오탐 이슈 폭증 가능성, 필터링 룰 필요
+  - 후속 티켓 후보: `TKT-P1-RUNTIME-AUTO-ISSUE`
+
+- `IDEA-004` (status: proposed)
+  - 제목: PR 코멘트 워크플로우 자동 점검(리뷰어->개발논의->검증승인 누락 차단)
+  - 배경: 현재 절차는 강력하지만 수행 확인이 수동
+  - 기대효과: 절차 누락 방지, 감사 추적 자동화
+  - 리스크: CLI/API 연동 유지보수 비용
+  - 후속 티켓 후보: `TKT-P0-WORKFLOW-GUARD`

@@ -5,14 +5,24 @@
 **CRITICAL: All code changes MUST follow this workflow. Direct pushes to `main` are ABSOLUTELY PROHIBITED.**
 
 1. **Create Gitea Issue First** — All features, bug fixes, and policy changes require a Gitea issue before any code is written
-2. **Create Feature Branch** — Branch from `main` using format `feature/issue-{N}-{short-description}`
-   - After creating the branch, run `git pull origin main` and rebase to ensure the branch is up to date
-3. **Implement Changes** — Write code, tests, and documentation on the feature branch
-4. **Create Pull Request** — Submit PR to `main` branch referencing the issue number
-5. **Review & Merge** — After approval, merge via PR (squash or merge commit)
+2. **Create Program Feature Branch** — Branch from `main` for the whole development stream
+   - Format: `feature/{epic-or-stream-name}`
+3. **Create Ticket Temp Branch** — Branch from the program feature branch per ticket
+   - Format: `feature/issue-{N}-{short-description}`
+4. **Implement Per Ticket** — Write code, tests, and documentation on the ticket temp branch
+5. **Create Pull Request to Program Feature Branch** — `feature/issue-N-* -> feature/{stream}`
+6. **Review/Verify and Merge into Program Feature Branch** — user approval not required
+7. **Final Integration PR to main** — Only after all ticket stages complete and explicit user approval
 
 **Never commit directly to `main`.** This policy applies to all changes, no exceptions.
 
+## Branch Strategy (Mandatory)
+
+- Team operation default branch is the **program feature branch**, not `main`.
+- 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.

 ## Gitea CLI Formatting Troubleshooting
 
 Issue/PR 본문 작성 시 줄바꿈(`\n`)이 문자열 그대로 저장되는 문제가 반복될 수 있다. 원인은 `-d "...\n..."` 형태에서 쉘/CLI가 이스케이프를 실제 개행으로 해석하지 않기 때문이다.
