# Sundew Health Monitor

**Neurosymbolic, energy-aware AI for continuous ECG monitoring**

Combines adaptive gating, ML inference, and symbolic reasoning to deliver trustworthy, energy-efficient medical biosignal monitoring.

## Key Features

- **85% energy reduction** via Sundew gating algorithm
- **Explainable alerts** through symbolic rule chains
- **Real-time streaming** with WebSocket support
- **Multi-patient dashboard** for clinical monitoring
- **Production-ready API** with comprehensive SDK

## Quick Start

### Docker (Recommended)
```bash
docker-compose up --build
```
API: http://localhost:8000 | Docs: http://localhost:8000/docs

### Local Development
```bash
pip install -e . --extra-index-url https://download.pytorch.org/whl/cpu
alembic upgrade head
uvicorn app.main:app --reload
```

### Live Demo
```bash
python app_space_live.py
```

## Architecture

```
ECG Stream → Sundew Gating → ML Inference → Rule Engine → Alert
              (50-90% reduction)  (PyTorch CNN)   (Symbolic)
```

**Three-stage neurosymbolic pipeline:**
1. **Gating** - Adaptive windowing with significance scoring
2. **Inference** - Energy-efficient neural network
3. **Rules** - Medical knowledge base for explainability

## API Endpoints

- `POST /ecg/infer` - Run full pipeline
- `WS /ws/ecg/{patient_id}` - Real-time streaming
- `GET /dashboard/stats` - System metrics
- `GET /dashboard/patients` - Patient summaries
- `GET /dashboard/alerts` - Alert queue

## SDK Usage

```python
from sundew_sdk import SundewClient

client = SundewClient(base_url="http://localhost:8000")
result = client.infer_ecg(
    patient_id="p001",
    signal=[...],
    age=72,
    has_prior_stroke=False
)

print(f"{result['label']} | Alert: {result['alert_level']}")
```

See `sdk/example_client.py` for complete examples.

## Benchmarking

Evaluate against MIT-BIH Arrhythmia Database:

```bash
bash scripts/run_full_benchmark.sh
```

**Metrics tracked:**
