To identify shallow modules for refactoring, scan the codebase to find instances where interface complexity nearly matches implementation complexity, creating maintenance friction and testing difficulties. This process reveals tightly-coupled logic scattered across modules that should be consolidated behind smaller, high-leverage interfaces to improve modularity and testability.

A deep module in software architecture is a module with a small, simple interface that hides complex implementation logic, creating a clear seam for maintenance. Deep modules matter because they reduce tight coupling, boost testability, and enhance AI navigability by consolidating scattered logic into high-leverage units.

To refactor tightly-coupled code for testability and modularity, consolidate scattered logic into deeper modules with small, leveraged interfaces. This approach reduces the friction where small changes require editing dozens of scattered modules, ensuring network state and component handling are grouped into testable units.

Yes, you need architectural decision records and project domain glossaries to improve codebase architecture effectively. Accessing these resources ensures that refactoring recommendations respect existing project vocabulary and past architectural decisions, generating context-aware suggestions that align with established conventions.

Yes, you can use codebase architecture refactoring for game projects like Subspace Infinity. The process identifies areas such as networking state sync and ECS component handling split across shallow modules, proposing refactors to consolidate them into deeper, more testable units with clear seams.

The best way to align refactoring suggestions with existing domain vocabulary is to use the project's existing domain glossary, such as a CONTEXT.md file, alongside architectural decision records. This ensures all deepening opportunities match the codebase's established terminology and past decisions.
