The Refactoring Priority Premise (RPP) is a progressive framework that improves maintainability by enforcing a mandatory cascade through six levels, focusing on readability before architectural changes to ensure safe, incremental codebase transformations.

To systematically refactor legacy code, apply the RPP ladder starting with Level 1 readability improvements, utilizing a catalog of 22 code smells and atomic transformations to execute safe, incremental changes before advancing to higher architectural levels.

Code readability must be prioritized before architectural refactoring because the progressive framework enforces a mandatory sequence, requiring you to complete Level 1 readability improvements before advancing to higher levels for architectural refinement.

The best way to structure incremental refactoring is using a multi-level hierarchy from L1 to L6, applying atomic transformations and clear guidelines to steadily improve code quality while maintaining test smells and project health.

Progressive refactoring does not require specific dependencies or components, allowing you to apply the RPP-based level progression and 22 code smell taxonomy directly to your existing codebases without external tool integrations.

Code refactoring breaks project health when bypassing the mandatory L1 to L6 cascade, but you can prevent this by following clear guardrails and practical guidelines for safe, incremental changes that maintain test smells during transformations.
