## Purpose

Source: AI-written repository summary; verify against source.

> Guava is Google's core Java utility library providing immutable collections (multimap, multiset), a graph library, and utilities for concurrency, I/O, hashing, primitives, and strings.

## Main parts

> Core Base Utilities: Foundational utilities for objects, strings, patterns, and functional abstractions used across the library.

## Evidence gaps

> Dependencies were not checked for known security issues. That does not mean there are none.
> RepoPilot has not run the setup commands or tests.
> No public API or start-up file could be picked out from the file names.
> An installation or usage excerpt was not captured. Read the README for how to use the published project.
> Runtime versions and other prerequisites were not captured.
> Root development commands were not established. Check the root manifest and contributor guide.
> Setup has not been executed. Environment variables, external services and command order may require additional source documentation.
