You identify shallow module boundaries by analyzing codebase areas for deepening opportunities that increase module depth through well-defined interfaces and seams, requiring evidence gathering from vault documentation and code inspection.

The best way to make codebase refactors testable is classifying dependencies as in-process, local-substitutable, remote-owned with ports and adapters, or true external with mocks, guiding how the deepened module should be tested through interface-based testing surfaces.

A grilling loop improves software architecture decisions by walking through constraints, seam placement, adapters, and interface test surfaces, reasoning about dependency categories to ensure confident refactoring decisions and recording vault docs only when justified.

Yes, you can improve AI navigability by reducing architectural friction through deepening refactors that turn shallow modules into deep ones using clear module, interface, and seam language grounded in your vault documentation and code evidence.

You should avoid module deepening when premature interface changes are required, as the approach requires candidate presentation without premature interface changes and only records vault documentation when constraints and seam placement are fully justified.
