Policy, Lifecycle, and Intent Extensions for OAuth Rich Authorization Requests

OAuth 2.0 Rich Authorization Requests (RAR) [RFC9396] defines a syntax for clients to request fine-grained permissions. While powerful, this mechanism lacks standardized methods for clients to express three critical contextual dimensions prevalent in modern automated systems: the high-level user intent driving the request, the required security policy under which the request should be evaluated, and the binding of the authorization's lifecycle to an external process. This document extends the RAR framework to address these gaps. It first defines a new authorization_details type, *intent_request*, to facilitate goal-oriented authorization. Second, it introduces two new parameters for the authorization_details object: *policy_context*, to request authorization under a specific assurance level, and *lifecycle_binding*, to tie the validity of the authorization grant to the state of an external entity. These extensions enable authorization servers to make more intelligent, secure, and context-aware decisions, particularly in ecosystems involving autonomous agents and complex, long-running tasks.
