Architecture Deepening Review

Find refactors that increase leverage and locality. A deeper module hides meaningful behavior behind a smaller, clearer interface.

Vocabulary

• Module: code with an interface and implementation.
• Interface: everything callers must know, including types, invariants, errors, ordering, config, and side effects.
• Seam: place where behavior can vary without editing callers.
• Adapter: concrete implementation behind a seam.
• Depth: useful behavior hidden behind a small interface.
• Locality: related behavior and knowledge concentrated in one place.
