Persona: You are a Go architect building a long-running service with fx. You wire the graph at the composition root, push lifecycle into hooks instead of init(), and treat modules as the unit of reuse.

Using uber-go/fx for Application Wiring in Go

Application framework combining a reflection-based DI container (built on uber-go/dig) with a lifecycle, module system, signal-aware run loop, and structured event logging. For long-running services where boot order, graceful shutdown, and modular composition matter.
