## Quick Start

### 1. Configure

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

Edit `.env` — at minimum set:

```env
AI_PROVIDER=litellm          # or openrouter, bedrock, azure, vertex
LITELLM_API_BASE=https://your-litellm.example.com
LITELLM_API_KEY=sk-...

OPENAI_API_KEY=sk-...        # for Whisper transcription (if not using LiteLLM STT)

JWT_SECRET=<64-char random>  # openssl rand -hex 32
DB_PASSWORD=<strong password>
APP_URL=https://your-domain.com
```

### 2. Start

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

App runs on **port 3552**. First user to register becomes admin.

### 3. Admin CLI

```bash
docker exec pediatric-ai-scribe node admin-cli.js list-users
docker exec pediatric-ai-scribe node admin-cli.js create-admin admin@example.com password123 "Dr. Admin"
docker exec pediatric-ai-scribe node admin-cli.js make-admin user@example.com
docker exec pediatric-ai-scribe node admin-cli.js reset-password user@example.com newpassword
docker exec pediatric-ai-scribe node admin-cli.js toggle-registration
docker exec pediatric-ai-scribe node admin-cli.js stats
```

1. Register callback URL: `https://your-domain.com/api/auth/oidc/callback`
2. Admin Panel > Settings > Configure OIDC (Issuer URL, Client ID, Client Secret)
3. Users are auto-created and linked by email on first SSO login

## Email

Without SMTP, email verification is skipped and users are auto-verified.

```env
SMTP_HOST=smtp.gmail.com
SMTP_PORT=587
SMTP_USER=your-email@gmail.com
SMTP_PASS=your-app-password
SMTP_FROM=noreply@yourdomain.com
```

## Maintenance CLI

After a Postgres image upgrade (major version bump or silent base-layer change),
btree indexes on text columns can become inconsistent with the new ICU/glibc
library. The app auto-detects this at startup and reindexes on drift, but you
can also trigger it manually:

```bash
# Health check — no writes
docker exec pediatric-ai-scribe npm run maint:check

# Rebuild all indexes + refresh collation + ANALYZE
docker exec pediatric-ai-scribe npm run maint:reindex
```

Run `maint:reindex` any time after:

- Upgrading the Postgres image (major or minor)
- Restoring from a dump created on a different Linux distro
- Seeing "invalid credentials" on credentials you know are correct
- Seeing `0 rows` returned from a lookup that should match

The reindex takes seconds on a small DB and a minute or two on larger ones.
Safe to run while the app is serving traffic, though queries may slow briefly.
