## Overview

This is a simulated astronaut health-monitoring and explainable expert-system application. The principal workflow is a client submitting crew, environmental-system, and log data to the API; the application persists readings and logs, derives alerts, and exposes status and history. Expert-analysis endpoints use the rule engine to produce explainable findings and retain decision records. The excerpts show API validation, SQLite operations, alert logic, and expert-engine functions; several endpoint details and the knowledge-base loading path are unsampled, so those links are left unverified.

Main entry points: [`main.py`](https://github.com/userstr193/health_monitoring_for_nasa_competition/blob/main/main.py) (API and monitoring), [`expert_system.py`](https://github.com/userstr193/health_monitoring_for_nasa_competition/blob/main/expert_system.py) (Rule evaluation), [`knowledge_base.json`](https://github.com/userstr193/health_monitoring_for_nasa_competition/blob/main/knowledge_base.json) (Rule catalog)
