Supplementary Materials for The Time-Travel Evidence Lab: Later Verification of AI-Agent Actions

Reproducible supplementary artifact package for a case study on later verification of AI-agent actions. The archive contains local synthetic experiment harnesses, public source-neighbor corpus metadata, standards-adjacent cryptographic adapter checks, source-neighbor search artifacts, verification scripts, and paper-facing traceability materials. The package is a research artifact and does not claim production deployment, legal compliance, certification, trust-service provision, standards conformance, public auditability, third-party validation, or proof of absolute novelty.
