Evidence Graphs for Agentic Trust Fabrics

Key Points

This work aims to explore how agent evidence can be represented as evidence graphs within trust fabrics.
Synthetic case study utilizing MCP and EUDI Wallet-style credentials.
Incorporation of diverse technologies including X-Road, SPIFFE/SPIRE, and post-quantum signatures.
Compilation of reproducibility notes and public-clean evidence summaries.
Presentation of agent evidence as predicate-level evidence graphs.
Identification of PKI as critical governance infrastructure for agentic public-service systems.

Abstract

Preprint package for a synthetic human-in-the-loop case study across MCP, EUDI Wallet-style credentials, X-Road, SPIFFE/SPIRE, Rekor, Vault transit, and post-quantum signatures. The package contains the manuscript source, generated color figures, public-clean evidence summaries, case matrices, reproducibility notes, adjacent-case manifest, and checksum material. The work frames agent evidence as predicate-level evidence graphs and treats PKI as governance infrastructure adjacent to agentic public-service systems.
