The CI pipeline validates project structure and build system:

# CI validation (works now)
make test                   # Project structure validation
./validate_project.sh      # Comprehensive project health check

# Build testing (requires NASM)
make test-build            # Validates successful compilation

📋 Code Guidelines

Romantic Coding Standards

• Use relationship metaphors consistently
• Write code that tells a love story
• Comment your code as if explaining to your significant other
• Test thoroughly - we want stable relationships!
• Keep functions small and focused (like perfect date plans)

Naming Conventions

• Variables: camelCase (e.g., myLoveStory, firstDate)
• Functions: snake_case with romantic names (e.g., propose_marriage, calculate_love_score)
• Constants: UPPER_CASE (e.g., ETERNAL_LOVE, MAX_ROMANCE_LEVEL)

Example Code Style

# Good: Romantic and clear
marry couple_names couple["Alice", "Bob"]
propose plan_perfect_date(location, activity):
    marry date_plan memory[
        "location": location,
        "activity": activity,
        "romance_level": 100
    ]
    promise date_plan

# Comments should be loving and helpful
# This function calculates the compatibility between two people
propose calculate_compatibility(person1, person2):
    # Love always finds a way! 💕
    promise love
