To improve codebase testability, you need to identify shallow, tightly-coupled modules and consolidate them into deep units with stable interfaces. This surfaces architectural friction and eliminates redundant wrappers that scatter complexity across call sites.

Module deepening in software architecture is the process of consolidating implementation behind small, stable interfaces to concentrate complexity. It transforms shallow modules where interface complexity matches implementation into leverage-rich, testable units.

Preparing codebases for AI coding agents requires enforcing seam discipline and eliminating shallow wrappers to ensure clear module boundaries. This allows agents to navigate fragmented structures without getting lost in tightly-coupled dependencies.

You need to prioritize codebase refactoring for mid-to-large projects when maintainability drops due to tightly-coupled modules and untestable code paths. An architecture review surfaces these deepening opportunities to consolidate scattered complexity.

Fixing shallow modules that leak seams requires identifying tightly-coupled code paths and consolidating them into deep modules. This enforces seam discipline and hides implementation details behind small, stable interfaces to restore maintainability.

Codebase architecture analysis works independently of specific testing frameworks by evaluating structural design rather than executing tests. It identifies tightly-coupled modules and leaked seams that reduce testability and AI navigability.
