Agent-to-User Interfaces (A2UI): A Deterministic Framework for Machine-Readable Knowledge Systems.

Abstract Agent-to-User Interfaces (A2UI) introduce a deterministic interface model that transforms technical content into machine-readable, executable knowledge systems. This approach is demonstrated through the PADI Sovereign Bureau, which operationalizes structured artifacts, graph-based reasoning, and protocol-driven execution into a unified knowledge architecture. 1. Philosophy: Epistemic Visibility as a Function of Schema In the traditional record of technological progress, the "erasure" of marginalized pioneers is often framed as social or historical bias. From an Information Science perspective, this is more precisely understood as a structural data failure, where contributions are not encoded in formats compatible with computational retrieval systems. In agent-mediated environments, epistemic visibility becomes a function of schema compliance and indexability. If a contribution is not represented in a machine-readable structure (e.g., JSON-LD, graph nodes, or registry entries),
