"""
Pre-deployment validation script for MathPulse AI backend.

This script runs BEFORE deployment to catch issues early and prevent
restart loops on HF Spaces.

Usage:
    python backend/pre_deploy_check.py

Exit codes:
    0: All checks passed, safe to deploy
    1: Critical issue found, deployment should be blocked
