🟡 Changes recommended
Offline mode currently emits a provider error event despite being treated as a ready/usable state elsewhere, which can misreport provider status to OpenFeature clients.
Once you've addressed the issues Copilot identified, you can request another Copilot review.

Greptile Summary
The PR introduces the initial FeatBit provider integration for the Ruby OpenFeature SDK.
Confidence Score: 5/5
The PR appears safe to merge, with no outstanding correctness or repository-rule failures.
The change since the previous review only disables persisted checkout credentials, while all later workflow operations remain read-only and require no Git authentication. deleteLater dismissed the earlier mutable-action-reference finding, and its thread was resolved.
