Overview

Minimal stdlib HTTP client for the updater and Tier B executor.

  • Always sends a descriptive User-Agent (some endpoints 403 UA-less clients; it's also basic politeness toward the volunteer-run sources this gem depends on).
  • Follows redirects across hosts — GitHub release downloads ALWAYS redirect to objects.githubusercontent.com / release-assets.…; if your egress is allowlisted, those hosts must be on the list too.
  • Supports conditional GET via ETag (returns :not_modified).
  • Never talks to api.github.com (60 req/hr unauthenticated limit); releases/download// asset URLs redirect fine without auth.
