AI Analysis
●●SolidBig BrainNiche Gem
Explain mode traces rule evaluation node-by-node when Symfony can't.
Strengths
- •Node-by-node explain mode shows exactly why rules passed or failed
- •Strict typing prevents silent type coercion bugs in rule evaluation
- •Safe mode collects all missing variables instead of failing on first
Weaknesses
- •Cannot access object properties or call methods limits enterprise use cases
- •Smaller operator surface than Symfony ExpressionLanguage for complex rules
