## What it is
run.Group is a small Go library providing a universal mechanism to manage goroutine lifecycles. Actors are added as execute/interrupt function pairs, and Run orchestrates concurrent execution with well-defined shutdown semantics.

## Use cases
- manage goroutine lifecycles in Go
- gracefully shut down an HTTP server on exit
- orchestrate multiple background workers as a unit
- run components in func main with clean teardown
- cancel goroutines via context when one exits

## When to choose
- you need coordinated startup and shutdown of multiple goroutines
- you want a smaller API than errgroup or tomb without context requirements
- you're wiring long-running services in a main function

## When to avoid
- you only need simple fire-and-forget goroutines
- you need staged shutdown semantics built in
- you're not writing Go

## Facets
- artifact type: library
- maturity: stable
- function: concurrency, error-handling
- domain: developer-tools, backend
- platform: go, cross-platform
- tags: goroutines, lifecycle-management, graceful-shutdown
