## AI overview

This article explains how dependency-injection code can expose architectural debt. It identifies signals such as oversized modules, string qualifiers, lifetime inversion, construction that starts work, broad production-container tests, and definitions spread across UI locations. It recommends paying down debt at product-slice boundaries, separating construction from behavior, adding focused graph and behavior tests, and measuring ownership, verification, startup, and test setup.

## Source excerpt

Dependency-injection code is often treated as plumbing. It is also a compact map of architecture decisions. Review it for debt signals before adding another binding. Signals worth investigating An oversized application module usually means feature boundaries are not explicit. String qualifiers can hide a missing type. Definitions that open databases or start jobs during graph creation mix construction with behavior. A process-scoped object that accepts a screen-owned dependency indicates lifetime inversion.
