PR #1810 retired the host-global gh token detection that injected GITHUB_TOKEN into the request env, leaving both remote executors with a `_ = req` placeholder to silence the unused parameter. resolveGHToken is now just a filter over the selected credential IDs, so the parameter is gone from the Sprites and SSH flavors alike. Test asserts the pass-through selection value, not just length. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
