# saju-lab 신설 + tarot-lab 분리 Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** agent-office에 종속된 tarot을 독립 tarot-lab 컨테이너로 분리하고, 별도 디렉토리의 saju-web을 saju-lab 컨테이너로 마이그레이션 (Python FastAPI + Claude + SQLite 패턴).

**Architecture:** Phase 1은 코드 복사 + DB 1회 마이그레이션 + agent-office cutover. Phase 2는 TypeScript 계산 엔진을 Python으로 reference-output 비교 테스트 기반 포팅 + Claude AI 해석 파이프라인 (tarot 패턴 재활용) + 사주/궁합 v1 endpoint. 두 lab 모두 `insta-lab`/`music-lab`과 동일 디렉토리 구조.

**Tech Stack:** Python 3.12 + FastAPI 0.115 + httpx + Pydantic V2 + SQLite WAL + Anthropic Claude Sonnet 4.6 (prompt-caching) + sxtwl (Python 만세력) + pytest + respx (httpx mock).

**Reference spec:** `docs/superpowers/specs/2026-05-25-saju-tarot-lab-migration-design.md`

## Phase 1 — tarot-lab 분리

### Task 1: tarot-lab 스캐폴딩 (Dockerfile + requirements + pytest.ini)

**Files:**
- Create: `tarot-lab/Dockerfile`
- Create: `tarot-lab/requirements.txt`
- Create: `tarot-lab/pytest.ini`
- Create: `tarot-lab/.dockerignore`
- Create: `tarot-lab/app/__init__.py`
- Create: `tarot-lab/tests/__init__.py`

- [ ] **Step 1: Dockerfile 작성 (insta-lab 패턴)**

```dockerfile
FROM python:3.12-slim-bookworm
ENV PYTHONUNBUFFERED=1

WORKDIR /app

COPY requirements.txt .
RUN pip install --no-cache-dir --timeout 600 --retries 5 -r requirements.txt

COPY . .

EXPOSE 8000
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8000", "--workers", "1"]
```

- [ ] **Step 2: requirements.txt 작성**

```
fastapi==0.115.6
uvicorn[standard]==0.34.0
httpx>=0.27
pydantic>=2.9
pytest>=8.0
pytest-asyncio>=0.24
respx>=0.21
```

- [ ] **Step 3: pytest.ini 작성**

```ini
[pytest]
asyncio_mode = auto
pythonpath = .
```

- [ ] **Step 4: .dockerignore 작성**

```
__pycache__
*.pyc
.pytest_cache
data/
tests/
```

- [ ] **Step 5: 빈 app/__init__.py, tests/__init__.py 생성**

빈 파일 2개 생성:
- `tarot-lab/app/__init__.py`
- `tarot-lab/tests/__init__.py`

- [ ] **Step 6: 디렉토리 구조 확인**

Run: `ls tarot-lab/ tarot-lab/app/ tarot-lab/tests/`
Expected: 각각 파일 존재 확인

- [ ] **Step 7: Commit**

```bash
git add tarot-lab/Dockerfile tarot-lab/requirements.txt tarot-lab/pytest.ini tarot-lab/.dockerignore tarot-lab/app/__init__.py tarot-lab/tests/__init__.py
git commit -m "feat(tarot-lab): 스캐폴딩 — Dockerfile + requirements + pytest"
```

---

### Task 2: tarot-lab config.py + models.py

**Files:**
- Create: `tarot-lab/app/config.py`
- Create: `tarot-lab/app/models.py`

- [ ] **Step 1: app/config.py 작성**

```python
"""tarot-lab 환경변수."""
import os

ANTHROPIC_API_KEY = os.getenv("ANTHROPIC_API_KEY", "")
TAROT_MODEL = os.getenv("TAROT_MODEL", "claude-sonnet-4-6")
TAROT_COST_INPUT_PER_M = float(os.getenv("TAROT_COST_INPUT_PER_M", "3.0"))
TAROT_COST_OUTPUT_PER_M = float(os.getenv("TAROT_COST_OUTPUT_PER_M", "15.0"))
TAROT_TIMEOUT_SEC = int(os.getenv("TAROT_TIMEOUT_SEC", "180"))

TAROT_DATA_PATH = os.getenv("TAROT_DATA_PATH", "/app/data")
DB_PATH = os.path.join(TAROT_DATA_PATH, "tarot.db")

CORS_ALLOW_ORIGINS = os.getenv(
    "CORS_ALLOW_ORIGINS",
    "http://localhost:3007,http://localhost:8080",
)
```

- [ ] **Step 2: app/models.py 작성**

```python
"""Tarot Pydantic 모델 — agent-office models.py에서 추출."""
from typing import List, Literal, Optional

from pydantic import BaseModel, Field


class TarotCardDraw(BaseModel):
    position: str
    card_id: str
    reversed: bool = False


class TarotInterpretRequest(BaseModel):
    spread_type: Literal["one_card", "three_card"]
    category: Optional[str] = None
    question: Optional[str] = None
    cards: List[TarotCardDraw]
    cards_reference: str = Field(..., min_length=1)
    context_meta: dict = Field(default_factory=dict)


class TarotInterpretResponse(BaseModel):
    interpretation_json: dict
    model: str
    tokens_in: int
    tokens_out: int
    cost_usd: float
    latency_ms: int
    reroll_count: int = 0


class TarotSaveRequest(BaseModel):
    spread_type: Literal["one_card", "three_card"]
    category: Optional[str] = None
    question: Optional[str] = None
    cards: List[TarotCardDraw]
    interpretation_json: dict
    model: str
    tokens_in: int
    tokens_out: int
    cost_usd: float
    confidence: Optional[str] = None


class TarotPatchRequest(BaseModel):
    favorite: Optional[bool] = None
    note: Optional[str] = None
```

```bash
git add tarot-lab/app/config.py tarot-lab/app/models.py
git commit -m "feat(tarot-lab): config + Pydantic 모델 5개 추출"
```

### Task 3: tarot-lab db.py (CRUD 5 + _tarot_row_to_dict + init_db)

**Files:**
- Create: `tarot-lab/app/db.py`
- Create: `tarot-lab/tests/test_db.py`

**중요한 변경점**: monkeypatch가 `db_module.DB_PATH`를 덮어쓸 수 있도록 `_conn()` 내부에서 `config.DB_PATH`를 매번 읽어옴. agent-office는 `from .config import DB_PATH`로 import 하지만 테스트 monkeypatch가 module-level 변수를 덮어쓰는 패턴이 더 안정적.

수정: 테스트에서 `monkeypatch.setattr(db_module, "DB_PATH", str(db_file))`로 db_module 자체의 DB_PATH를 덮어쓰므로, db.py 안에서 `DB_PATH`를 직접 참조해야 함. 다시 작성:

```python
import json
import os
import sqlite3
from typing import Any, Dict, Optional

from .config import DB_PATH


def _conn() -> sqlite3.Connection:
    os.makedirs(os.path.dirname(DB_PATH), exist_ok=True)
    conn = sqlite3.connect(DB_PATH, timeout=120.0)
    # ... 이하 동일
```

테스트의 `monkeypatch.setattr(db_module, "DB_PATH", ...)`가 module의 `DB_PATH` (import된 값)를 직접 덮어쓰므로 정상 동작.

- [ ] **Step 4: Run tests, verify they pass**

Run: `cd tarot-lab && python -m pytest tests/test_db.py -v`
Expected: 4 passed

### Task 11: agent-office에서 tarot 모듈 cutover 제거

**Files:**
- Delete: `agent-office/app/tarot/` (디렉토리)
- Delete: `agent-office/app/routers/tarot.py`
- Modify: `agent-office/app/main.py`
- Modify: `agent-office/app/models.py`
- Modify: `agent-office/app/db.py`
- Modify: `agent-office/app/config.py`
- Delete: `agent-office/tests/test_tarot_db.py`
- Delete: `agent-office/tests/test_tarot_pipeline.py`
- Delete: `agent-office/tests/test_tarot_routes.py`
- Delete: `agent-office/tests/test_tarot_schema.py`

**⚠️ 사전 조건**: NAS에서 마이그레이션 스크립트를 실행해 tarot_readings 데이터를 tarot.db로 옮긴 후 진행. 검증:
```bash
docker exec agent-office python /app/scripts/migrate_tarot_to_lab.py
# 출력: "migrated N / N rows"
docker exec tarot-lab python -c "import sqlite3; print(sqlite3.connect('/app/data/tarot.db').execute('SELECT COUNT(*) FROM tarot_readings').fetchone())"
# 출력: (N,) ← agent-office의 N과 일치해야 함
```

- [ ] **Step 1: agent-office/app/main.py에서 tarot router import + include 제거**

L15 `from .routers import tarot as tarot_router` 줄 삭제.
L19 `app.include_router(tarot_router.router)` 줄 삭제.

- [ ] **Step 2: agent-office/app/models.py에서 Tarot* 5개 제거**

L38~L78 (TarotCardDraw / TarotInterpretRequest / TarotInterpretResponse / TarotSaveRequest / TarotPatchRequest) 블록 삭제.

- [ ] **Step 3: agent-office/app/db.py에서 tarot 관련 5 CRUD + helper 제거**

L798~L909 (`# --- tarot_readings CRUD ---` 주석부터 `_tarot_row_to_dict` 함수 끝까지) 전체 삭제.

CREATE TABLE `tarot_readings` 블록 (L134~L160, idx_tarot_created/idx_tarot_favorite 인덱스 포함)은 **유지** — 운영 DB에 이미 있는 테이블을 DROP하지 않기 위함. 기존 데이터는 archive 역할로 남겨두고 30일 후 manual cleanup.

- [ ] **Step 4: agent-office/app/config.py에서 TAROT_* 제거**

L43~L46 TAROT_MODEL / TAROT_COST_INPUT_PER_M / TAROT_COST_OUTPUT_PER_M / TAROT_TIMEOUT_SEC 4줄 삭제.

- [ ] **Step 5: 디렉토리 + 라우터 + 테스트 파일 삭제**

```bash
rm -rf agent-office/app/tarot/
rm agent-office/app/routers/tarot.py
rm agent-office/tests/test_tarot_db.py
rm agent-office/tests/test_tarot_pipeline.py
rm agent-office/tests/test_tarot_routes.py
rm agent-office/tests/test_tarot_schema.py
```

- [ ] **Step 6: agent-office import 잔여 흔적 검색**

Run: `grep -rn "tarot" agent-office/app/ agent-office/tests/`
Expected: scripts/migrate_tarot_to_lab.py만 매치 (그 외 매치 0)

- [ ] **Step 7: agent-office pytest 통과 확인**

Run: `cd agent-office && python -m pytest -v --ignore=tests/test_migrate_tarot.py 2>&1 | tail -20`
Expected: PASS (tarot 제외 다른 테스트 정상 동작)

- [ ] **Step 8: Commit**

```bash
git add -A agent-office/
git commit -m "refactor(agent-office): tarot 모듈 제거 (tarot-lab으로 cutover 완료)"
```

### Task 12: web-ui api.js URL prefix 변경 + Phase 1 e2e 검증

**Files:**
- Modify: `web-ui/src/api.js:745-770`

⚠️ web-ui는 별도 git 저장소. 작업 디렉토리 이동 필요.

- [ ] **Step 1: web-ui로 cd 후 api.js 6개 endpoint URL 변경**

`web-ui/src/api.js`의 6개 함수 URL을 변경:

| 함수 | 기존 | 변경 |
|------|------|------|
| `tarotInterpret` | `/api/agent-office/tarot/interpret` | `/api/tarot/interpret` |
| `tarotSaveReading` | `/api/agent-office/tarot/readings` | `/api/tarot/readings` |
| `tarotListReadings` | `/api/agent-office/tarot/readings?...` | `/api/tarot/readings?...` |
| `tarotGetReading` | `/api/agent-office/tarot/readings/${id}` | `/api/tarot/readings/${id}` |
| `tarotPatchReading` | `/api/agent-office/tarot/readings/${id}` | `/api/tarot/readings/${id}` |
| `tarotDeleteReading` | `/api/agent-office/tarot/readings/${id}` | `/api/tarot/readings/${id}` |

Sed 일괄 치환 가능:
```bash
cd ../web-ui
# Bash on Windows: 6 함수 모두 같은 prefix → 한 번에 치환
# Edit 도구 또는 sed로 '/api/agent-office/tarot/' → '/api/tarot/' 일괄 변경
```

- [ ] **Step 2: web-ui 잔여 검색**

Run: `cd ../web-ui && grep -rn "/api/agent-office/tarot" src/`
Expected: 매치 0건

- [ ] **Step 3: web-backend 로컬 docker compose 기동 (선택)**

Run: `cd ../web-backend && docker compose up -d tarot-lab nginx frontend agent-office`
Expected: tarot-lab + nginx + agent-office healthy

- [ ] **Step 4: 로컬 e2e — npm run dev 후 /tarot 페이지 1회 리딩**

Run: `cd ../web-ui && npm run dev`
브라우저: http://127.0.0.1:3007/tarot/reading
- 3장 스프레드 1회 실행
- AI 인사이트 탭에서 응답 확인
- "리딩 저장" 클릭 → /tarot/history에서 보이는지 확인
- 즐겨찾기 토글 / 삭제 동작 확인

Expected: 모든 동작 정상 (네트워크 탭에서 `/api/tarot/*` 호출 확인)

- [ ] **Step 5: Commit web-ui**

```bash
cd ../web-ui
git add src/api.js
git commit -m "feat(api): tarot endpoint를 /api/tarot/* 로 이전 (agent-office 분리)"
cd ../web-backend
```

---

## Phase 1 완료 ✓

Phase 1 종료 시점 점검:
- [ ] `tarot-lab/` 디렉토리에 21개 테스트 모두 통과
- [ ] `docker-compose.yml`에 tarot-lab 항목 존재 (18250)
- [ ] `nginx/default.conf`에 `/api/tarot/` location 존재
- [ ] deploy 스크립트 5위치 모두 tarot-lab 포함
- [ ] `agent-office/app/tarot/` 디렉토리 + `routers/tarot.py` 삭제됨
- [ ] `agent-office/app/db.py`에 tarot_readings CREATE는 유지, CRUD는 제거
- [ ] `agent-office/scripts/migrate_tarot_to_lab.py` 존재 + 테스트 3건 통과
- [ ] `web-ui/src/api.js`의 tarot 6 helper가 `/api/tarot/*` 사용
- [ ] 로컬 e2e: /tarot에서 1회 리딩 + 저장 + 삭제 정상

NAS 배포 절차 (사용자 수동):
1. `cd web-backend && git push` → Gitea Webhook → deployer 자동 배포
2. 배포 완료 후 SSH에서 마이그레이션 1회 실행:
   ```bash
   ssh nas
   docker exec agent-office python /app/scripts/migrate_tarot_to_lab.py
   # "migrated N / N rows" 확인
   docker exec tarot-lab python -c "import sqlite3; print(sqlite3.connect('/app/data/tarot.db').execute('SELECT COUNT(*) FROM tarot_readings').fetchone())"
   ```
3. 운영 /tarot 페이지에서 1회 리딩 확인
4. `cd web-ui && npm run release:nas` (api.js 변경 적용)

## Phase 2 — saju-lab 신설

Phase 2는 작업량이 큽니다(계산 엔진 ~1500줄 TypeScript → Python 포팅 + Claude 통합 + DB/Router/UI). Phase 1 완료를 확인한 후 시작하세요.

> **참고**: Phase 2 시작 전 saju-web 디렉토리의 `lib/saju-calculator.ts`, `lib/ai-interpretation.ts`, `lib/daeun-calculator.ts`, `lib/solar-terms.ts`, `app/compatibility/*` 파일을 모두 열어 reference 구현을 숙지할 것. spec의 Section 6 참조.

### Task 13: saju-lab 스캐폴딩

**Files:**
- Create: `saju-lab/Dockerfile`
- Create: `saju-lab/requirements.txt`
- Create: `saju-lab/pytest.ini`
- Create: `saju-lab/.dockerignore`
- Create: `saju-lab/app/__init__.py`
- Create: `saju-lab/tests/__init__.py`
- Create: `saju-lab/tests/fixtures/__init__.py`
- Create: `saju-lab/app/calculator/__init__.py`
- Create: `saju-lab/app/interpret/__init__.py`
- Create: `saju-lab/app/routers/__init__.py`

- [ ] **Step 1: Dockerfile (insta-lab 패턴)**

```dockerfile
FROM python:3.12-slim-bookworm
ENV PYTHONUNBUFFERED=1

WORKDIR /app

COPY requirements.txt .
RUN pip install --no-cache-dir --timeout 600 --retries 5 -r requirements.txt

COPY . .

EXPOSE 8000
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8000", "--workers", "1"]
```

- [ ] **Step 2: requirements.txt**

```
fastapi==0.115.6
uvicorn[standard]==0.34.0
httpx>=0.27
pydantic>=2.9
sxtwl>=2.0
pytest>=8.0
pytest-asyncio>=0.24
respx>=0.21
```

> `sxtwl` 은 Python에서 만세력(60갑자·24절기·음력) 계산을 제공. TS의 `solarlunar` 대체.

- [ ] **Step 3: pytest.ini + .dockerignore + 빈 __init__.py 5개**

`saju-lab/pytest.ini`:
```ini
[pytest]
asyncio_mode = auto
pythonpath = .
```

`saju-lab/.dockerignore`:
```
__pycache__
*.pyc
.pytest_cache
data/
tests/
```

빈 파일 5개:
- `saju-lab/app/__init__.py`
- `saju-lab/tests/__init__.py`
- `saju-lab/tests/fixtures/__init__.py`
- `saju-lab/app/calculator/__init__.py`
- `saju-lab/app/interpret/__init__.py`
- `saju-lab/app/routers/__init__.py`

- [ ] **Step 4: Commit**

```bash
git add saju-lab/
git commit -m "feat(saju-lab): 스캐폴딩 — Dockerfile + requirements + 디렉토리 구조"
```

### Task 14: Reference output fixture 생성 (Node.js로 saju-web 실행 → JSON)

**Files:**
- Create: `saju-lab/tests/fixtures/generate_reference.cjs` (Node.js 스크립트)
- Create: `saju-lab/tests/fixtures/reference_saju.json` (생성 결과)

이 task는 Python 포팅 검증의 안전망입니다. saju-web의 TypeScript 계산 엔진을 Node.js로 직접 실행해 입력→출력 쌍 30~50건을 JSON 파일로 저장.

- [ ] **Step 1: saju-web 디렉토리에서 build 산출물 확인**

Run: `ls C:/Users/jaeoh/Desktop/workspace/saju-web/lib/`
Expected: `saju-calculator.ts`, `ai-interpretation.ts`, `daeun-calculator.ts`, `solar-terms.ts` 등 존재

> TypeScript를 직접 실행하려면 `ts-node` 또는 빌드 산출물(`.next/server/...`) 사용. 가장 간단한 경로는 saju-web의 dev 서버를 띄우고 `/api/analyze`를 호출해 결과를 fetch 하는 것이지만, 그러면 OpenAI API 호출이 일어남. 대신 계산 부분만 추출하기 위해 임시 .cjs 스크립트로 lib만 호출.

- [ ] **Step 2: generate_reference.cjs 작성**

```javascript
// Run: node generate_reference.cjs > reference_saju.json
// (ts-node 또는 tsc 빌드 후 실행)

const ts = require('ts-node').register({
  transpileOnly: true,
  compilerOptions: { module: 'commonjs', target: 'es2020' },
});

const SAJU_WEB = '../../../../saju-web';
const { calculateSaju } = require(`${SAJU_WEB}/lib/saju-calculator`);
const { performFullAnalysis } = require(`${SAJU_WEB}/lib/ai-interpretation`);
const { calculateDaeun } = require(`${SAJU_WEB}/lib/daeun-calculator`);

  { year: 1965, month: 1, day: 20, hour: 23, gender: 'male' },
  { year: 1973, month: 7, day: 4, hour: 17, gender: 'female' },
];

const CURRENT_YEAR = 2026;

const out = CASES.map(input => {
  const saju = calculateSaju(input.year, input.month, input.day, input.hour, input.gender);
  const analysis = performFullAnalysis(saju, CURRENT_YEAR);
  const daeun = calculateDaeun(
    input.year, input.month, input.day,
    input.gender, saju.month.stem, saju.month.branch,
  );
  return { input, expected: { saju, analysis, daeun } };
});

console.log(JSON.stringify(out, null, 2));
```

- [ ] **Step 3: 생성 + 저장**

```bash
cd saju-lab/tests/fixtures
# saju-web에 ts-node 설치되어 있는지 확인:
# ls ../../../../saju-web/node_modules/ts-node || (cd ../../../../saju-web && npm install --save-dev ts-node)
node generate_reference.cjs > reference_saju.json
```

검증:
```bash
python -c "import json; data = json.load(open('reference_saju.json')); print(f'{len(data)} cases')"
```
Expected: `30 cases`

- [ ] **Step 4: Commit**

```bash
git add saju-lab/tests/fixtures/generate_reference.cjs saju-lab/tests/fixtures/reference_saju.json
git commit -m "feat(saju-lab): reference fixture 30 케이스 (Node로 TS 엔진 결과 추출)"

### Task 18~22 (계산 엔진 나머지)

> **주의**: Task 18~22는 spec Section 6-1의 포팅 순서를 정확히 따라야 하며, 각 task는 같은 패턴(reference fixture 비교 테스트 + Python 구현)으로 진행. 코드 양이 매우 많으므로 별도 sub-skill인 subagent-driven-development로 위임하는 것이 권장. 각 task의 핵심 계약과 테스트 패턴만 plan에 명시.

### Task 18: calculator/core.py (60갑자 + 십성 + 십이운성 + calculate_saju)

**Files:**
- Create: `saju-lab/app/calculator/core.py`
- Create: `saju-lab/tests/test_core.py`

**핵심 계약:**
- `get_year_ganzi(year) → {stem, branch, stem_kr, branch_kr, element, ...}`
- `get_month_ganzi(year, month, day) → ...` (절기 기반, solar_terms.get_solar_term_month_branch 사용)
- `get_day_ganzi(year, month, day) → ...` (만세력 — sxtwl.fromSolar로 일주 추출)
- `get_hour_ganzi(day_stem, hour) → ...`
- `get_ten_god(day_stem, target_stem, is_target_yang) → "비견"|"겁재"|"식신"|"상관"|"편재"|"정재"|"편관"|"정관"|"편인"|"정인"`
- `get_twelve_fortune(day_stem, branch) → "장생"|"목욕"|"관대"|"임관"|"제왕"|"쇠"|"병"|"사"|"묘"|"절"|"태"|"양"`
- `calculate_saju(year, month, day, hour, gender) → SajuData dict`

**테스트 패턴 (test_core.py):**

```python
import json
from pathlib import Path
import pytest

from app.calculator.core import calculate_saju


REF = json.loads((Path(__file__).parent / "fixtures" / "reference_saju.json").read_text(encoding="utf-8"))

    inp = case["input"]
    expected = case["expected"]["saju"]
    actual = calculate_saju(inp["year"], inp["month"], inp["day"], inp.get("hour"), inp["gender"])
    
    # 4기둥 모두 비교
    for pillar in ["year", "month", "day", "hour"]:
        if expected.get(pillar) is None:
            assert actual.get(pillar) is None
            continue
        for field in ["stem", "branch", "stem_kr", "branch_kr", "element", "ten_god", "fortune"]:
            assert actual[pillar][field] == expected[pillar][field], \
                f"{pillar}.{field} mismatch: {actual[pillar][field]} vs {expected[pillar][field]}"
    
    assert actual["day_stem"] == expected["dayStem"] or actual["day_stem"] == expected["day_stem"]
    assert actual["gender"] == expected["gender"]
```

> **camelCase vs snake_case**: TypeScript는 camelCase (`dayStem`, `meaningUpright`), Python은 snake_case 표준. Reference JSON은 TS camelCase로 직렬화되어 있으므로 비교 시 키 변환 필요. core.py의 `calculate_saju`는 snake_case 출력 + 비교 fixture는 양쪽 키 모두 시도 (위처럼 `or`).

- `get_current_daeun(daeun_list, current_year) → DaeunPillar`
- `get_daeun_description(daeun, day_stem) → str`

대운 방향(순행/역행)은 양남음녀=순행, 음남양녀=역행. `get_days_to_next_solar_term`으로 시작 나이 계산.

- [ ] Step 1~10: 동일 패턴 + reference 30 케이스의 daeun 비교

### Task 22: calculator/compatibility.py (궁합 점수)

**핵심 계약:**
- `calculate_compatibility(saju_a, saju_b) → {score: 0-100, breakdown: dict}`
- breakdown 항목: 일간 오행 상생/상극, 지지 합/충 매칭, 십성 배합, 신살 영향

saju-web의 `app/compatibility/` 디렉토리 코드를 reference로 사용.

**테스트:**
- 알려진 좋은 궁합 (예: 갑목일주 + 정화일주 = 상생) → 점수 70+
- 알려진 충돌 (예: 자오충, 인신충 강하게 결합) → 점수 30-
- breakdown JSON 구조 검증

- [ ] **Step 4: Run schema tests**

Run: `cd saju-lab && python -m pytest tests/test_schema.py -v`
Expected: 5 passed

- [ ] **Step 5: Commit**

```bash
git add saju-lab/app/interpret/prompt.py saju-lab/app/interpret/schema.py saju-lab/tests/test_schema.py
git commit -m "feat(saju-lab): interpret/prompt.py + schema.py — 12항목 + 궁합 SYSTEM_PROMPT"
```

### Task 25: interpret/pipeline.py (사주 + 궁합 Claude 호출)

**Files:**
- Create: `saju-lab/app/interpret/pipeline.py`
- Create: `saju-lab/tests/test_pipeline.py`

- [ ] **Step 1~5: tarot-lab/app/pipeline.py 패턴 그대로 재활용**

`saju-lab/app/interpret/pipeline.py`:
- `interpret_saju(saju, analysis, daeun, current_year) → dict` (tokens, cost, latency 포함)
- `interpret_compat(saju_a, saju_b, analysis_a, analysis_b, score, breakdown) → dict`
- 두 함수 모두 같은 `_call_claude` helper 공유 (system/user_text/validate만 다름)
- `max_tokens=2400` (12항목이라 더 길게)
- reroll 1회
- prompt-caching `cache_control: ephemeral`

테스트(`tests/test_pipeline.py`): respx mock으로 success/codeblock/reroll/validate-fail/http-error/cost 6 case + compat 동일 6 case = 총 12 case.

- [ ] **Step 6: Run + Commit**

```bash
git add saju-lab/app/interpret/pipeline.py saju-lab/tests/test_pipeline.py
git commit -m "feat(saju-lab): interpret/pipeline.py — Claude 호출 + reroll (12 tests)"
```

---

### Task 26: routers/saju.py + routers/compat.py + app/main.py

**Files:**
- Create: `saju-lab/app/routers/saju.py`
- Create: `saju-lab/app/routers/compat.py`
- Create: `saju-lab/app/main.py`
- Create: `saju-lab/tests/test_routes.py`

**API 엔드포인트:**

`routers/saju.py` 6개:
- `POST /api/saju/interpret` — 입력 → calculate_saju + perform_full_analysis + calculate_daeun + Claude interpret → DB save → 응답
- `GET /api/saju/readings` — list
- `GET /api/saju/readings/{id}` — get
- `PATCH /api/saju/readings/{id}` — favorite/memo
- `DELETE /api/saju/readings/{id}`
- `GET /api/saju/current-fortune?reading_id={id}` — 저장된 사주의 오늘 세운만 실시간 (AI 없음)

`routers/compat.py` 5개:
- `POST /api/saju/compat/interpret` — 두 사람 입력 → 두 사주 계산 + compatibility 점수 + Claude → DB save
- `GET /api/saju/compat/readings`
- `GET /api/saju/compat/readings/{id}`
- `PATCH /api/saju/compat/readings/{id}`
- `DELETE /api/saju/compat/readings/{id}`

`main.py`는 tarot-lab과 동일 구조 + 두 router include.

테스트(`tests/test_routes.py`): TestClient + Claude pipeline mock으로 11 endpoint 모두 검증 (interpret 호출 시 pipeline.interpret_saju/compat을 monkeypatch).

- [ ] **Step 1~10**: 6 endpoint(saju) + 5(compat) 각각 작성/테스트

- [ ] **Step 11: Run all saju-lab tests**

Run: `cd saju-lab && python -m pytest -v`
Expected: 70+ tests passing (constants 5 + solar_terms 32 + lunar 2 + core 30 + shinsal 10+ + analysis 30 + daeun 30 + compatibility 10+ + db 10 + schema 5 + pipeline 12 + routes 11)

- [ ] **Step 12: Commit**

```bash
git add saju-lab/app/main.py saju-lab/app/routers/ saju-lab/tests/test_routes.py
git commit -m "feat(saju-lab): main.py + routers (saju 6 + compat 5) + 11 route tests"
```

### Task 27: docker-compose.yml + nginx + deploy scripts (saju-lab 등록)

**Files:**
- Modify: `docker-compose.yml`
- Modify: `nginx/default.conf`
- Modify: `scripts/deploy.sh` (5 위치 추가)
- Modify: `scripts/deploy-nas.sh` (SERVICES 추가)

- [ ] **Step 1: docker-compose.yml에 saju-lab 추가 (tarot-lab 다음)**

```yaml
  saju-lab:
    build:
      context: ./saju-lab
    container_name: saju-lab
    restart: unless-stopped
    ports:
      - "18300:8000"
    environment:
      - TZ=${TZ:-Asia/Seoul}
      - ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY:-}
      - SAJU_MODEL=${SAJU_MODEL:-claude-sonnet-4-6}
      - SAJU_COST_INPUT_PER_M=${SAJU_COST_INPUT_PER_M:-3.0}
      - SAJU_COST_OUTPUT_PER_M=${SAJU_COST_OUTPUT_PER_M:-15.0}
      - SAJU_TIMEOUT_SEC=${SAJU_TIMEOUT_SEC:-240}
      - SAJU_DATA_PATH=/app/data
      - CORS_ALLOW_ORIGINS=${CORS_ALLOW_ORIGINS:-http://localhost:3007,http://localhost:8080}
    volumes:
      - ${RUNTIME_PATH:-.}/data/saju:/app/data
    healthcheck:
      test: ["CMD", "python", "-c", "import urllib.request; urllib.request.urlopen('http://localhost:8000/health')"]
      interval: 60s
      timeout: 5s
      retries: 3
```

- [ ] **Step 2: nginx/default.conf — tarot 다음에 saju 추가**

```nginx
  # saju-lab API
  location /api/saju/ {
    resolver 127.0.0.11 valid=10s;
    set $saju_backend saju-lab:8000;

    proxy_http_version 1.1;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_read_timeout 300s;
    proxy_send_timeout 300s;
    proxy_connect_timeout 60s;
    proxy_pass http://$saju_backend$request_uri;
  }

```

- [ ] **Step 3: scripts/deploy-nas.sh SERVICES에 saju-lab 추가**

```bash
SERVICES="lotto travel-proxy deployer stock music-lab insta-lab realestate-lab agent-office personal packs-lab video-lab image-lab tarot-lab saju-lab nginx scripts"
```

- [ ] **Step 4: scripts/deploy.sh 4개 변수에 saju-lab + saju 디렉토리**

```bash
BUILD_TARGETS="lotto travel-proxy stock music-lab insta-lab realestate-lab agent-office personal packs-lab video-lab image-lab tarot-lab saju-lab frontend"
CONTAINER_NAMES="lotto stock music-lab insta-lab blog-lab realestate-lab agent-office personal packs-lab travel-proxy video-lab image-lab tarot-lab saju-lab frontend"
HEALTH_ENDPOINTS="lotto stock travel-proxy music-lab insta-lab realestate-lab agent-office personal packs-lab video-lab image-lab tarot-lab saju-lab redis"
DATA_DIRS="music stock insta realestate agent-office personal video image tarot saju"
```

- [ ] **Step 5: Commit**

```bash
git add docker-compose.yml nginx/default.conf scripts/deploy.sh scripts/deploy-nas.sh
git commit -m "feat(deploy): saju-lab 컨테이너 + nginx + 5위치 동기화"
```

### Task 28: web-ui api.js + routes.jsx + Icons (saju helpers)

**Files (web-ui repo):**
- Modify: `web-ui/src/api.js`
- Modify: `web-ui/src/routes.jsx`
- Modify: `web-ui/src/components/Icons.jsx`

- [ ] **Step 1: api.js에 saju + compat helpers 추가 (tarot helper 다음에)**

```javascript
// ====== Saju ======

export function sajuInterpret(body) {
  return apiPost('/api/saju/interpret', body);
}

export function sajuListReadings({ page = 1, size = 20, favorite } = {}) {
  const qs = new URLSearchParams();
  qs.set('page', page); qs.set('size', size);
  if (favorite !== undefined) qs.set('favorite', favorite);
  return apiGet(`/api/saju/readings?${qs.toString()}`);
}

export function sajuGetReading(id) {
  return apiGet(`/api/saju/readings/${id}`);
}

export function sajuPatchReading(id, body) {
  return apiPatch(`/api/saju/readings/${id}`, body);
}

export function sajuDeleteReading(id) {
  return apiDelete(`/api/saju/readings/${id}`);
}

export function sajuCurrentFortune(readingId) {
  return apiGet(`/api/saju/current-fortune?reading_id=${readingId}`);
}

// ====== Compatibility ======

export function compatInterpret(body) {
  return apiPost('/api/saju/compat/interpret', body);
}

export function compatListReadings({ page = 1, size = 20, favorite } = {}) {
  const qs = new URLSearchParams();
  qs.set('page', page); qs.set('size', size);
  if (favorite !== undefined) qs.set('favorite', favorite);
  return apiGet(`/api/saju/compat/readings?${qs.toString()}`);
}

export function compatGetReading(id) {
  return apiGet(`/api/saju/compat/readings/${id}`);
}

export function compatPatchReading(id, body) {
  return apiPatch(`/api/saju/compat/readings/${id}`, body);
}

export function compatDeleteReading(id) {
  return apiDelete(`/api/saju/compat/readings/${id}`);
}
```

- [ ] **Step 2: routes.jsx에 saju 라우트 4개 + navLinks 추가**

기존 tarot 라우트 패턴 따라:
- `/saju` → SajuLanding
- `/saju/reading` → Saju (입력 + 결과)
- `/saju/compatibility` → Compatibility
- `/saju/history` → SajuHistory

> **참고**: 실제 React 컴포넌트 파일(Saju.jsx, Compatibility.jsx 등)은 시안 받은 후 작성. 현재 task는 라우트 등록 + 빈 placeholder 컴포넌트만 추가.

- [ ] **Step 3: Icons.jsx에 IconSaju 추가**

(임시 SVG — 8괘 또는 음양 심볼)

- [ ] **Step 4: Commit (web-ui)**

```bash
cd ../web-ui
git add src/api.js src/routes.jsx src/components/Icons.jsx
git commit -m "feat(saju): api helpers (saju + compat) + 라우트 + 아이콘"
cd ../web-backend
```

---

### Task 29: web-ui /saju UI 페이지 (시안 받은 후)

**Files (web-ui repo):**
- Create: `web-ui/src/pages/saju/Saju.jsx`
- Create: `web-ui/src/pages/saju/SajuForm.jsx`
- Create: `web-ui/src/pages/saju/SajuResult.jsx`
- Create: `web-ui/src/pages/saju/Compatibility.jsx`
- Create: `web-ui/src/pages/saju/CompatibilityResult.jsx`
- Create: `web-ui/src/pages/saju/SajuHistory.jsx`
- Create: `web-ui/src/pages/saju/Saju.css`
- Create: `web-ui/src/pages/saju/data/constants.js`
- Create: `web-ui/src/pages/saju/hooks/useSajuForm.js`
- Create: `web-ui/src/pages/saju/hooks/useSajuInterpretation.js`
- Create: `web-ui/src/pages/saju/components/SajuBoard.jsx`
- Create: `web-ui/src/pages/saju/components/ElementChart.jsx`
- Create: `web-ui/src/pages/saju/components/DaeunTimeline.jsx`
- Create: `web-ui/src/pages/saju/components/InterpretationPanel.jsx`

**⚠️ 이 Task는 사용자로부터 UI 시안 이미지를 받은 후 진행**합니다. 시안 없이 진행하면 재작업 가능성이 높음.

시안 받으면 tarot 페이지(`web-ui/src/pages/tarot/`) 구조를 참조하여 동일 패턴으로 구성:
- 입력 폼 → useSajuForm hook
- API 호출 → useSajuInterpretation hook (sajuInterpret 호출, AI 응답 도착 시 자동 탭 전환)
- 결과 페이지: 4기둥 시각화 + 오행 차트 + 대운 타임라인 + 12항목 아코디언
- 디자인은 saju-web 디자인 시스템(딥 네이비 + 골드)을 web-ui에 맞춰 조정

상세 컴포넌트 명세는 시안 + spec Section 6-6 + saju-web 디렉토리 참고.

- [ ] **Step 1~N**: 시안 도착 후 별도 mini-plan으로 진행

```bash
git commit -m "feat(saju): web-ui /saju 페이지 — 입력/결과/궁합/히스토리"
```

---

## Phase 2 완료 ✓

Phase 2 종료 시점 점검:
- [ ] `saju-lab/`에 모든 테스트 통과 (목표: 130+ tests)
- [ ] Reference fixture 30 케이스 모두 saju 계산 일치
- [ ] `docker-compose.yml`에 saju-lab 항목 존재 (18300)
- [ ] `nginx/default.conf`에 `/api/saju/` location 존재
- [ ] deploy 스크립트 5위치 모두 saju-lab 포함
- [ ] `web-ui/src/api.js`에 saju + compat helpers
- [ ] `web-ui/src/routes.jsx`에 /saju 라우트 (UI는 시안 후)

NAS 배포 절차:
1. `cd web-backend && git push` → 자동 배포
2. 배포 완료 후 SSH:
   ```bash
   docker logs -f saju-lab  # 시작 확인
   curl http://localhost:18300/health
   ```
3. 시안 받으면 web-ui Phase 2 UI 진행

## 전체 검증 체크리스트

### Phase 1 검증
- [ ] tarot-lab pytest 21 passed
- [ ] agent-office migrate_tarot pytest 3 passed
- [ ] agent-office에서 tarot import 0건 (grep 검색)
- [ ] 로컬 e2e: /tarot 리딩 1회 성공
- [ ] git log: 12 commit (Task 1~12)

### Phase 2 검증
- [ ] saju-lab pytest 130+ passed
- [ ] reference fixture 30 케이스 일치
- [ ] 로컬 e2e: /api/saju/interpret + /api/saju/compat/interpret 각 1회 성공 (curl 또는 Swagger)
- [ ] git log: Phase 1 + Phase 2 총 28+ commit

### NAS 배포 후
- [ ] 두 컨테이너 모두 healthy
- [ ] 데이터 마이그레이션 후 tarot.db 행 수 = agent_office.db 의 tarot_readings 행 수
- [ ] /api/tarot/* 5분 SLA (504 없음)
- [ ] /api/saju/* 5분 SLA

---

## 위험 + 대응

| 위험 | 대응 |
|------|------|
| sxtwl API가 saju-web의 solarlunar와 절기 일자 1일 차이 | reference fixture 재생성 (Node→Python 모두 sxtwl 호환되도록) 또는 saju-web에 sxtwl 동등 라이브러리 적용 |
| 계산 엔진 포팅 reference 일부 mismatch | 해당 input 별도 issue 기록 + 30개 중 28~29건 통과 시 우선 통과로 처리 (다음 cycle에서 보강) |
| docker-compose의 RUNTIME_PATH가 호스트마다 다름 | `${RUNTIME_PATH:-.}/data/...` 패턴 (이미 다른 lab에서 사용 중) |
| Phase 2 UI 시안 지연 | Phase 2 백엔드만 먼저 배포 → /api/saju/* 사용 가능 (Swagger UI 또는 curl). UI는 시안 받은 후 |
| agent-office cutover 시점에 운영 tarot 요청 끊김 | nginx /api/tarot/ → tarot-lab 라우팅이 cutover 전에 추가되어 있어 끊김 없음 |
