Overview

Universal Request Context Adaptor for Ruby.

Extracts request data (host, query params, cookies, referer, x-forwarded-for, remote address) from a Rack-style environ hash or any framework request object that exposes #env (Rack, Rails, Sinatra). Falls back to empty defaults for nil or unrecognized inputs.
