feat(control): add live workboard v0

자기야 피드백: "픽셀 아트 안 예쁘다, profile photo 로 바꿀 수 없나?
픽셀 아트 고집 안 해도 됨." → 16x28 픽셀로는 anime 일러스트 정체성 못
살리는 게 사실. Phaser 자체도 큰 의존성이라 깔끔하게 빼고 React+CSS+SVG
로 재작성.

## 변경

### 제거
- phaser 4.0.0 의존성 (~3MB)
- frontend/components/office-rpg/ 전체 (Phaser 통합 layer + procedural
  pixel sprite factory + Office scene)

### 신설
- frontend/components/office-room/OfficeRoom.tsx
  - 2x2 grid layout: 하랑/나랑 (위), 다랑/이랑 (아래)
  - 가운데 회의실 (시각 표시만, 향후 인터랙션용)
  - 각 자매 = 책상 SVG 위에 원형 portrait card
    - 72px portrait (실제 /api/sisters/{name}/avatar)
    - 자매 시그니처 색 border (harang=blue, narang=teal, darang=red, erang=violet)
    - hover 시 위로 살짝 떠오름
    - 활성 stage 일 때 PulseRing + StatusDot 펄스
  - 자매 사이 SVG flow arrow (plan → impl → review → deploy 방향)
    활성 stage 시 화살표 hi-lighted
  - 클릭 → 우측 SisterDetailPanel slide-in
- frontend/components/office-room/SisterDetailPanel.tsx
  - 기존 office-rpg 의 detail panel 을 재사용 (PortraitLg + 자매 시그니처
    accent + 역할 설명 + 백엔드 sister info)

### app/page.tsx
- OfficeRpg → OfficeRoom 으로 교체
- 4초 polling 으로 활성 파이프라인의 currentState 추적 →
  STATE_TO_STAGE 매핑 → 해당 자매 카드 자동 펄스

+# 하나랑 대시보드 Rebuild From Scratch Implementation Plan
+
+> **For Hermes:** 이 문서는 하랑이 planner role 산출물이다. 승인 전 구현/배포 금지. 승인 후 나랑이 builder 또는 Codex가 task 단위로 실행하고, 다랑이 reviewer가 spec/code quality를 검증한다.
+
+**Goal:** 기존 하나랑 대시보드를 “자기야가 4자매가 작업하는 과정을 실시간으로 보는 서비스”로 처음부터 다시 설계하고 구현한다. 메인 화면의 핵심은 이랑이/하랑이/나랑이/다랑이가 PLAN → BUILD → REVIEW → DEPLOY 흐름에서 무엇을 하고 있는지 live timeline/board/scene으로 보여주는 것이다.
+
+**Architecture:** 기존 `hanarang-dashboard` repo는 유지하되, 제품/정보구조/UI를 새로 잡는다. Frontend는 Next.js 16 + styled-components를 유지하고, Backend는 NestJS + Prisma/MariaDB + Socket.IO를 유지한다. 메인 서비스는 `4 Sisters Live Workboard`이며, v0는 mock event stream으로 “작업 과정이 보이는 화면”을 먼저 완성한다. v1에서 NestJS Socket.IO event stream과 workflow state API를 붙인다. 기존 코드는 삭제보다 `legacy` 보존/점진 교체를 우선한다.
+
+**Tech Stack:** Next.js 16, React 19, styled-components, NestJS 11, Prisma 7, MariaDB, Socket.IO, Hermes role skills, Proxmox read-only API.
+
+---
+
+## 0. 배경
+
+기존 대시보드는 다음 전제를 갖고 있었다.
+
+- 하랑/나랑/다랑/이랑이 각각 독립 gateway로 상시 동작
+- 4자매 서버 상태를 곧 agent 상태로 봄
+- OpenClaw/Lobster workflow 흔적이 UI에 남아 있음
+- 실시간 office/metaphor와 운영 패널이 섞여 있음
+
+현재 운영 방향은 바뀌었다.
+
+- 자기야의 기본 진입점은 이랑이 하나
+- 하랑=planner, 나랑=builder, 다랑=reviewer는 role skill로 호출
+- 하랑/나랑/다랑 gateway는 나중에 standby 전환 가능
+- Proxmox 서버 상태와 role runnable 상태를 분리해서 봐야 함
+- 하네스 엔지니어링 원칙: PLAN → 승인 → 구현 → QA → 배포 게이트
+
+그래서 단순 리팩토링보다 “처음부터 다시 만드는” 수준의 IA/UI 재설계가 맞다.
+
+---
+
+## 1. 제품 방향
+
+### 한 줄 정의
+
+하나랑 대시보드는 자기야가 **4자매가 작업하는 과정을 실시간으로 보는 서비스**다. 단순 관제센터가 아니라, 하랑이의 기획, 나랑이의 구현, 다랑이의 리뷰, 이랑이의 인프라/배포 판단이 어떤 순서로 흘러가는지 메인 화면에서 바로 보여준다.
+
+### 핵심 사용자
+
+- 자기야: 최종 사용자/승인자
+- 이랑이: 메인 비서, 오케스트레이터, 인프라 책임자
+- 하랑이 role: planner
+- 나랑이 role: builder
+- 다랑이 role: reviewer
+
+### 새 핵심 은유
+
+기존 “정적인 관제 카드 모음”이 아니라 **4자매 작업실을 실시간으로 보는 화면**이 메인이다.
+
+```text
+4 Sisters Live Workboard
+  ├─ Live Work Scene: 지금 누가 어떤 작업 중인지
+  ├─ Workflow Timeline: PLAN → BUILD → REVIEW → DEPLOY 이벤트 흐름
+  ├─ Active Task Focus: 현재 선택된 작업의 상세 상태
+  ├─ Sister Activity Lanes: 하랑/나랑/다랑/이랑 역할별 lane
+  └─ Infra/Approval Side Panel: 막힌 이유, 승인 필요, 인프라 위험
+```
+
+이랑이는 여전히 단일 진입점이지만, 화면의 주인공은 “이랑이 혼자”가 아니라 **4자매가 함께 일하는 과정**이다. 하랑/나랑/다랑이 gateway로 상시 떠 있지 않아도, role execution/event log를 통해 작업 과정이 보여야 한다.
+
+---
+
+## 2. Scope
+
+### 포함 — v0
+
+- 메인 화면을 `4 Sisters Live Workboard`로 설계
+- 하랑/나랑/다랑/이랑 activity lane
+- PLAN → BUILD → REVIEW → DEPLOY live timeline
+- 현재 작업 focus panel
+- approval/blocker side panel
+- mock event stream으로 실시간처럼 흐르는 UI
+- 새 AppShell/Navigation
+- 4자매 role status 카드
+- Proxmox monitoring link/panel placeholder
+- 프로젝트 list placeholder
+- mobile-first layout
+- mock/static data로 UI 완성
+- 기존 route와 충돌하지 않는 방식으로 새 route 구성
+
+### 포함 — v1
+
+- Backend API 계약 연결

+- Proxmox v0 live inventory 연결
+- project/workflow API 연결
+- Socket.IO live update 일부 적용
+
+### 포함 — v2

+- 도메인/Nginx 변경
+
+---
+
+## 3. Product IA
+
+### Primary Navigation
+
+1. **Live** — 4자매 작업 과정 실시간 메인 화면
+2. **Harness** — PLAN/Build/Review/Deploy 흐름 상세
+3. **Projects** — repo/project/sprint/task
+4. **Infra** — Proxmox/server/service health
+5. **Agents** — 이랑이 + 하랑/나랑/다랑 role health
+6. **Settings** — 토큰/환경/연동 상태. secret 값 표시 금지
+
+### Live 메인 화면
+
+메인 화면은 대시보드의 핵심 서비스다.
+
+상단:
+- 현재 active workflow 이름
+- live/snapshot/mock/fallback source badge
+- 전체 phase: Planning / Building / Reviewing / Waiting Approval / Deploying
+- pending approvals / blockers
+
+중앙:
+- **4 Sisters Live Workboard**
+  - 하랑 lane: 요구사항 정리, PLAN 작성, handoff
+  - 나랑 lane: 구현 task, test/build, diff 생성
+  - 다랑 lane: spec review, code review, QA 결과
+  - 이랑 lane: 인프라 확인, 배포 게이트, 위험 차단
+- 각 lane에는 현재 상태, 마지막 이벤트, 진행 중 작업, 다음 handoff를 표시한다.
+
+우측:
+- Active Task Focus
+  - 지금 선택한 이벤트/작업 상세
+  - 관련 파일/plan/QA report 링크
+  - tool call 또는 verification command 상태
+
+하단:
+- Workflow Timeline
+  - event stream 형태
+  - PLAN_CREATED, BUILD_STARTED, TEST_PASSED, REVIEW_REQUESTED, QA_FAILED, APPROVAL_NEEDED 같은 이벤트
+- Infra/Approval compact panel
+
+### Harness 화면
+
+Live 화면보다 상세한 작업 단위 board다.
+
+- workflow list
+- stage별 task cards
+- approval gates
+- QA report links
+- build/test logs
+
+### Agents 화면
+
+agent 상태를 4축으로 표시한다.
+
+| 항목 | 의미 |
+|---|---|
+| role | erang-main, harang-planner, narang-builder, darang-reviewer |
+| mode | main, role-skill, profile, gateway |
+| runnable | 현재 호출 가능한지 |
+| gateway | active, standby, failed, unknown |
+| server | LXC running 여부 |
+
+### Infra 화면
+
+처음엔 Proxmox monitoring PLAN과 연결한다.
+
+- `/infra/proxmox`
+- live-only v0
+- DB 없음
+- write action 없음
+
+---
+
+## 4. Design Principles
+
+1. **운영 판단이 먼저**
+   - 예쁜 오피스보다 “지금 위험한가?”를 먼저 보여준다.
+2. **상태의 출처를 숨기지 않음**
+   - live / snapshot / mock / fallback 구분.
+3. **상시 gateway와 role runnable을 분리**
+   - gateway standby는 장애가 아니다.
+4. **모바일 우선**
+   - 자기야 iPhone에서 빠르게 봐야 함.
+5. **과한 애니메이션 금지**
+   - 상태 파악 방해 금지.
+6. **하네스 원칙 내장**
+   - PLAN 승인 없이는 Build가 시작되지 않는 UI.
+
+---
+
+## 5. Repo Strategy
+
+### 기본 전략
+
+기존 repo 유지:
+
+```text
+/home/erang/hanarang-dashboard
+```
+
+새 구현은 기존 route를 바로 갈아엎지 않고, feature branch에서 새 구조를 만든다.
+
+추천 branch:
+
+```bash
+git checkout -b feature/rebuild-control-center
+```
+
+### 파일 구조 제안
+
+Frontend:
+
+```text
+frontend/app/(control)/page.tsx
+frontend/app/(control)/harness/page.tsx
+frontend/app/(control)/projects/page.tsx
+frontend/app/(control)/infra/page.tsx

+frontend/lib/control/types.ts
+frontend/lib/control/api.ts
+```
+
+Backend v0/v1:
+
+```text

+backend/src/infra/agents/agent-role-health.service.ts
+backend/src/infra/proxmox/*
+backend/src/control/control.controller.ts
+backend/src/control/control.service.ts
+```
+
+---
+
+## 6. Tasks
+
+### Task 1: 현재 구조 조사
+
+**Objective:** 새 대시보드를 얹을 수 있는 실제 route/component/API 구조를 확인한다.

+
+---
+
+### Task 4: Frontend live workboard skeleton

+- Create: `frontend/lib/control/mock-events.ts`
+
+**Rules:**
+- 기존 `frontend/app/page.tsx`를 바로 삭제하지 않는다.
+- 새 route가 충돌하면 `/control` 아래에 먼저 만든다.
+- mock data는 `source: 'mock'`을 반드시 표시한다.
+- 메인 화면의 첫 impression은 “4자매가 일하고 있다”여야 한다. 인프라/프로젝트 카드는 보조 패널로 둔다.
+
+**Verification:**
+
+```bash
+cd frontend
+npm run lint
+npm run build
+```
+
+---
+
+### Task 5: Harness detail board UI

+- gateway active/standby/failed와 runnable 분리
+
+---
+
+### Task 7: Infra summary placeholder
+
+**Objective:** Proxmox monitoring v0와 연결될 홈 요약 영역을 만든다.
+
+**Files:**

+- Create: `frontend/components/infra/ProxmoxSummaryCard.tsx`
+
+**Acceptance criteria:**
+- live/snapshot/mock source badge
+- critical 우선 정렬
+- `/infra/proxmox`로 이동 link
+
+---
+
+### Task 8: Backend live workflow summary API

+  activeWorkflow: WorkflowSummary | null;
+  sisters: SisterActivityLaneState[];
+  events: WorkflowEvent[];
+  infra: InfraSummary;
+  approvals: ApprovalItem[];
+  source: 'live' | 'snapshot' | 'mock' | 'fallback';
+  updatedAt: string;
+};
+```
+
+**Verification:**
+
+```bash
+cd backend
+npm test -- control
+npm run build
+```
+
+---
+
+### Task 9: API client 연결
+
+**Objective:** frontend가 `/control/summary`를 읽고 실패 시 fallback mock을 쓴다.
+
+**Files:**
+- Create: `frontend/lib/control/api.ts`
+- Modify: `frontend/app/(control)/page.tsx`
+
+**Acceptance criteria:**

+
+---
+
+### Task 10: QA 문서 작성
+
+**Objective:** 다랑이가 검증할 QA checklist를 만든다.

+
+**Checks:**
+- iPhone viewport
+- source badge 정확성
+- gateway standby != down
+- mock/fallback 구분
+- PLAN approval gate 표시
+- build/lint pass
+
+---
+
+## 7. Approval Gates
+
+### Gate A — Rebuild plan approval
+
+지금 단계. 자기야가 이 PLAN을 승인해야 구현 시작 가능.
+
+### Gate B — Frontend v0 implementation
+
+허용:
+- frontend route/component 추가
+- mock/static data
+- no DB migration
+- no deploy
+
+### Gate C — Backend API v0
+
+허용:
+- read-only summary endpoint
+- mock/fallback service
+- no DB migration
+
+### Gate D — Proxmox integration
+
+별도 Proxmox monitoring PLAN과 연결.
+
+### Gate E — Deploy
+
+L3. 별도 승인 필요.
+
+---
+
+## 8. Rollback Plan
+
+- feature branch에서 작업한다.
+- 기존 `main`과 production route는 건드리지 않는다.
+- 새 route가 문제면 branch 폐기 또는 route 제거.
+- 배포 전까지 기존 사이트 영향 없음.
+
+---
+
+## 9. Open Questions
+
+1. 이름을 계속 `하나랑 대시보드`로 둘지, `하나랑 Control Center`로 바꿀지
+2. 첫 화면을 `/`로 교체할지, `/control`에서 먼저 검증할지
+3. 기존 오피스/등축 UI를 완전히 버릴지, 나중에 `Agents` 화면의 보조 시각화로 남길지
+4. 로그인/권한을 유지할지, 자기야 개인망 전용으로 단순화할지
+
+## 10. 이랑이 추천
+
+- 이름: `하나랑 Live Workboard` 또는 `하나랑 Control Center`
+- 메인 서비스: 4자매 작업 과정 실시간 화면
+- 구현 시작 route: `/control` 또는 `/live`
+- 기존 `/`는 당장 유지
+- v0는 mock event stream으로 “작업 과정이 보이는 화면”부터 완성
+- 이후 backend `/control/summary`, `/control/events` 연결
+- 마지막에 `/`를 새 live 화면으로 교체
+
+이 방식이면 자기야가 원하는 “4자매가 일하는 걸 실시간으로 보는 메인 서비스”를 먼저 만들고, 인프라/프로젝트 관제는 그 옆에 붙일 수 있어.

+  - 기존 사무실 메인 화면을 Live Workboard 메인 화면으로 교체
+- `frontend/app/control/page.tsx`
+  - `/control` route에서도 같은 Live Workboard 확인 가능
+- `frontend/components/common/Sidebar.tsx`
+  - nav에 `Live`, `Control` 항목 추가
+- `frontend/components/live/LiveWorkboard.tsx`
+  - 메인 Live Workboard container
+  - phase strip, 4자매 lane, active focus, timeline, v0 scope note 구성
+- `frontend/components/live/SisterActivityLane.tsx`
+  - 하랑/나랑/다랑/이랑 activity lane card
+- `frontend/components/live/WorkflowTimeline.tsx`

+  - 선택 이벤트 상세와 approval/risk panel
+- `frontend/lib/control/types.ts`
+  - Live Workboard 타입 정의
+- `frontend/lib/control/mock-events.ts`
+  - v0 mock workflow/sister/event/approval data
+
+## Verification
+
+- `npm run lint -- components/live app/control app/page.tsx lib/control components/common/Sidebar.tsx`: PASS
+- `npm run build`: PASS
+- `curl -I http://localhost:3004/`: HTTP 200 during dev server smoke test
+- Browser accessibility snapshot: `/`에 Live Workboard, 4자매 lane, Workflow Timeline, Active Task Focus 확인
+
+## Known Existing Issues
+
+- `npm run lint` 전체 실행은 기존 파일들의 React 19 lint rule 위반 때문에 FAIL.

+# Darang Review Report — Live Workboard v0
+
+## Verdict
+
+PASS WITH IMPORTANT NOTES
+
+## Spec Compliance
+
+- [x] 메인 화면의 핵심을 4자매 작업 과정 실시간 시각화로 변경했다.
+- [x] 하랑/나랑/다랑/이랑 activity lane을 구현했다.
+- [x] Workflow Timeline을 구현했다.
+- [x] Active Task Focus를 구현했다.
+- [x] Approval / Risk side panel을 구현했다.
+- [x] `source: mock · v0`를 UI에 명확히 표시했다.
+- [x] `/` 메인 화면과 `/control` route에서 Live Workboard를 볼 수 있다.
+- [x] DB migration, 배포, 인프라 변경 없이 frontend v0 범위만 수행했다.
+
+## Critical Issues
+
+없음.
+
+## Important Issues
+
+1. 전체 `npm run lint`는 기존 legacy 파일 오류 때문에 실패한다.
+   - 새 파일/수정 파일 대상 lint는 PASS.
+   - build는 PASS.
+2. 브라우저 vision 검증은 인증 상태 차이 때문에 로그인 화면을 보기도 했다.
+   - accessibility snapshot과 curl smoke에서는 `/` route가 정상 응답하고 Live Workboard 구조가 확인됐다.
+   - 실제 운영 계정 로그인 후 시각 QA가 한 번 더 필요하다.
+
+## Minor Issues
+
+- `/control`과 `/`가 같은 화면을 보여준다. v1에서 `/control`을 상세 관제 route로 분리할지 결정 필요.
+- mock event 자동 회전은 데모용이다. 실제 event stream 연결 시 선택 이벤트 유지 정책을 다시 정해야 한다.
+
+## Verification Checked
+
+- `npm run lint -- components/live app/control app/page.tsx lib/control components/common/Sidebar.tsx`: PASS
+- `npm run build`: PASS
+- `curl -I http://localhost:3004/`: PASS, HTTP 200
+- browser snapshot: PASS, Live Workboard 주요 섹션 확인
+
+## Deployment Risk
+
+Low for local/frontend code.
+
+이유:
+- frontend-only 변경
+- DB/인프라/배포 없음
+- 기존 office 컴포넌트 삭제 없음
+- production 반영은 아직 별도 승인 필요
+
+## Required Fixes Before Proceeding
+
+없음.
+
+## Recommended Next Step
+
+v1 전에 먼저 자기야가 화면 방향을 확인한다. 방향이 맞으면 다음 task는 backend event contract (`GET /control/summary`, `WS /control/events`) 설계/구현이다.
