Why this framework exists
The Authorization Coverage Lifecycle names the three phases every organization moves through as its ratio of governed agents to total agents changes. The naming matters because organizations in phase one often believe they are in phase three. The gap between where an organization thinks it is and where its authorization coverage ratio places it is itself a governance finding. Runtime enforcement specifications such as Microsoft's Agent Control Specification, published June 2, 2026, enforce authorization policy at five defined checkpoints in the agent lifecycle: input, model call, state transition, tool execution, and output (Microsoft Foundry Blog and Command Line blog, Build 2026, June 2, 2026); the Authorization Coverage Lifecycle governs the decision those controls enforce, upstream of the enforcement layer.
