## Quick Start

1. Copy env template:

```bash
cp .env.example .env
```

2. Set required values in `.env`:
- `POSTGRES_PASSWORD`
- `SESSION_SECRET_KEY`

3. Choose a deploy method below.

## Deploy Method A: Prebuilt Image (Recommended)

Use this for normal self-hosted deployment.

```bash
docker compose pull
docker compose up -d
```

Open:
- App/API: `http://localhost:8000`
- Health: `http://localhost:8000/healthz`

Upgrade:

```bash
docker compose pull
docker compose up -d
```

## Deploy Method B: Local Source Build + Dev Frontend

Use this for development on this repository.

```bash
docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d --build
```

Open:
- API (FastAPI): `http://localhost:8000`
- Frontend dev server (Vite): `http://localhost:5173`

Stop:

```bash
docker compose -f docker-compose.yml -f docker-compose.dev.yml down
```

## Essential Files

- `docker-compose.yml`: deployment compose (prebuilt image).
- `docker-compose.dev.yml`: dev override (source mounts + Vite dev server).
- `.env.example`: full env variable template.
- `Dockerfile`: multi-stage build (frontend + backend runtime).
- `README.md`: deployment and operations reference.
- `CONTRIBUTING.md`: contribution policy and merge checklist.
- `scripts/check_no_generated_artifacts.sh`: tracked-artifact guard used by CI.

## Data Model Notes

- Scholar tracking is user-scoped: each account can track the same Scholar ID independently.
- Publications are shared/global records deduplicated by Scholar cluster ID and normalized fingerprint.
- Per-account visibility and read state is stored on scholar-publication links, not on the global publication row.

## Name Search Status

- Scholar name search is intentionally WIP in the UI.
- Current Google Scholar behavior often redirects name-search traffic to login/challenge flows, so production onboarding should use direct Scholar ID/profile URL adds.

## Environment Variables (Complete Reference)

Notes:
- Boolean envs accept: `1/0`, `true/false`, `yes/no`, `on/off`.
- Values shown are deployment defaults from `.env.example` and `docker-compose.yml`.
- Some internal app fallbacks may differ for local test/dev safety when env vars are omitted.
- `deploy` means used in regular deployment.
- `dev` means used in local dev workflow.
