## AI overview

This tutorial recommends creating a framework-independent dependency-graph inventory before migrating dependency injection. It explains how to document entry points, ownership, implementations, lifetimes, qualifiers, modules, replacement values for tests, and architectural constraints, then validate the design through smaller executable test slices.

## Source excerpt

A dependency-injection migration often starts with framework syntax. That is too late. First describe the graph without using the framework's vocabulary. The inventory should show which objects exist, who owns them, and which runtime fact selects one implementation over another. Start from entry points List application entry points: the Android application, a worker, a navigation destination, a command-line process, and each test fixture. Trace the objects requested at each entry point. Stop the trace at explicit boundaries such as a database driver, HTTP transport, clock, file system, or platform service.
