code-design-refactor

To refactor a class violating single responsibility, extract tangled responsibilities into separate modules. Apply one behavior-preserving move at a time, then run tests and commit immediately to ensure strict encapsulation.

Decoupling modules within a single package requires extracting boundaries and tightening scope through small, incremental edits. Enforce a tests-first validation approach and commit each change to preserve behavior safely.

Design-level refactoring is needed when a function or class becomes too large or tangled. It helps tighten scope and improve module boundaries when responsibilities are muddled within your package architecture.

Improve encapsulation by applying small, one-move-at-a-time refactors to extract and decouple components. Enforce tests-first discipline before changes and commit each step to guarantee behavior preservation.

This refactoring approach applies to single-package boundaries and class or function level changes. It is specifically scoped to restructuring code within a package, not cross-package architecture modifications.
