Overview

Pure algorithm: Capture runtime environment info at boot time

Snapshots Ruby version, Rails version, loaded gem versions, web server, and database adapter. Memoized — computed once per process lifetime. Stored as JSON on each error so historical errors show the environment that was running when they occurred (not the current environment).
