Title: Authorization Evidence Chains: Composing Heterogeneous Agent-Action Evidence (EP-AEC)

Abstract:
Consequential agent actions can produce heterogeneous identity,
delegation, policy, permit, approval, transparency, capability, and
execution artifacts. Each artifact can verify under its own
specification while still referring to a different action, filling a
different evidentiary role, or failing a relying party's freshness,
status, or inter-artifact binding requirement. This document defines
the Authorization Evidence Chain (EP-AEC): a transport-agnostic
composition object and a fail-closed evaluation algorithm that
preserves native verification, establishes exact material-action
matching, and evaluates a relying-party-pinned evidence requirement.
AEC produces SATISFIED or UNSATISFIED and a replayable evaluation
record. SATISFIED means only that the presented evidence filled the
relying party's named evidence requirement at the stated verification
time. It is not a universal authorization decision, a policy
language for the protected application, or proof of execution or
outcome. The executor makes the separate local AUTHORIZED decision
and controls consumption, invocation, and effect handling. AEC
introduces no new component receipt type and does not replace any
native verifier.
