 2. Check for SOLID violations. Look for responsibilities that are mixed together, abstractions that are hard to replace or test, interface shapes that force unrelated dependencies, and code paths that require modifying stable code for each new variant.
 3. Check whether the implementation can be made simpler under KISS. Remove accidental abstractions, reduce branching, clarify names, and prefer the smallest structure that still supports the tested behavior and current spec.
