Confidence score: 4/5

• This PR has substantial changes but appears well-architected with proper error handling and follows established patterns
• Score reflects the complexity of webhook/trigger refactoring and knowledge base optimizations that could have edge cases in production
• Pay close attention to the trigger handler refactoring and PDF batching logic which involve critical data processing workflows
