Simplification Cascades

To consolidate repeated codebase patterns, identify all existing variants across modules and derive a unifying abstraction to collapse multiple implementations into one generic handler. This eliminates duplicated logic and reduces maintenance risk.

The best way to refactor duplicated handlers and validators is to apply a simplification cascade that extracts a general solution covering all variants. This removes the need for multiple special cases and implementations.

You should collapse scattered implementations when you identify similar patterns repeated across modules, such as five similar handlers or rules, and can replace them with one generic implementation to decrease maintenance and edge cases.

To extract a unifying principle from similar configurators, discover where the same concept is implemented in multiple places and specify a single concrete abstraction, scope of changes, and validation steps to replace them.

A limitation of replacing multiple special cases with a single cascade is the need to specify validation steps and fallbacks required for the generic implementation to ensure it safely covers all previously scattered edge cases.
