Oracle JPMorgan Chase & Co Telefonica Aryaka This document defines five actor-chain profiles for OAuth 2.0 Token Exchange {{!RFC8693}}. {{!RFC8693}} permits nested act claims, but prior actors remain informational only and token exchange does not define how a delegation path is preserved and validated across successive exchanges. This document defines profile-specific processing for linear multi- hop workflows. The profiles are Asserted Delegation Path, Selectively Disclosed Asserted Delegation Path, Committed Delegation Path, Commitment-Only Delegation Path, and Selectively Disclosed Committed Delegation Path. These profiles preserve the existing meanings of sub and act, support same- domain and cross-domain delegation, require sender-constrained tokens, and provide different tradeoffs among readable chain-based authorization, cryptographic accountability, auditability, privacy, and long-running workflow support.
