Critical infrastructure incident report with high technical depth and actionability.
Ruby Central's inability to directly manage GitHub Business/Enterprise admin rights during offboarding triggered a September 2025 walkout by six core maintainers. The fracture stemmed from neglected offboarding runbooks and the conflation of GitHub access with production control, exposing critical single-point-of-failure risks in open source project governance.
