## Project Overview

Galaxis-Po is a quant portfolio management application for DC pension (퇴직연금) investing. It implements the Kim Jong-bong (김종봉) strategy for backtesting, signal generation, and portfolio management. The strategy logic is defined in `quant.md` — do not modify it without explicit instruction.

## Tech Stack

- **Backend:** FastAPI, Python 3.12, SQLAlchemy, PostgreSQL, uv (package manager)
- **Frontend:** Next.js 15 (App Router), React 19, TypeScript, Tailwind CSS v4, shadcn/ui (Radix primitives)
- **Infrastructure:** Docker Compose, PostgreSQL 18

## Common Commands

```bash
# Backend dev server (from repo root)
cd backend && uv run uvicorn app.main:app --reload

# Frontend dev server
cd frontend && npm run dev

# Run all backend tests
cd backend && uv run pytest

# Run e2e tests
cd backend && uv run pytest tests/e2e/ -v

# DB migration
cd backend && uv run alembic upgrade head

# Create new migration
cd backend && uv run alembic revision --autogenerate -m "description"

# Frontend lint
cd frontend && npm run lint

# Frontend type check
cd frontend && npx tsc --noEmit
```

## Development Rules

1. Check `docs/plans/` for relevant design documents before implementing features
2. All API endpoints go under `backend/app/api/` as routers
3. DB schema changes require an alembic migration — autogenerate 후 반드시 리뷰하고 즉시 `alembic upgrade head`
4. Do not modify `.env` or `docker-compose.prod.yml` (`.env` 설정 안내는 허용, 자동 수정은 금지)
5. External APIs: pykrx (한국 거래소 데이터, 백테스트/시그널 주력), KIS (실시간 매매), DART (재무제표)
6. Frontend 변경 후 `cd frontend && npx tsc --noEmit` 필수
