Planning a major refactor for maintainability involves identifying primitives, drawing black-box boundaries to hide internal implementations, and wrapping dependencies to ensure safe substitutions. This structured approach maps module boundaries and risks before any code changes occur.

Defining explicit input and output interfaces is achieved by drawing black-box boundaries around modules. This technique hides internal implementations, enforces clear data contracts for primitive operations, and isolates external dependencies to improve overall system replaceability.

Wrapping external dependencies requires enforcing dedicated wrappers around external services to enable safe substitutions. This architecture review process isolates third-party components behind explicit module boundaries, allowing you to swap dependencies without modifying core business logic.

You need an architecture review for dependency introductions when planning major refactors or making architecture decisions across modules. It helps identify primitive data types crossing boundaries and produces a structured report of risks and recommendations before integration.

Yes, this architecture review process is specifically designed to identify primitive data types and operations crossing module boundaries. It enforces a four-phase process to discover primitives, map dependencies, and output a structured report with module boundaries and risks.

Applying black-box boundaries to existing code requires careful identification of primitives and dependency wrapping. If internal implementations are deeply coupled, enforcing explicit input and output interfaces may require significant refactoring to isolate external dependencies properly.
