AffixIO Agentic Proof Gap Demo

Version 1.0 · Published April 2026 · Technical Whitepaper

This whitepaper defines the controls required to move from transaction-only correctness to accountable machine actions using signed decision envelopes and verifiable execution traces.

Control objectives

• Signed provenance for who/what produced a decision.
• Tamper-evident trace integrity via root recomputation.
• Challenge freshness checks to block replay use.
• Policy hash binding to reject version drift and downgrade paths.

Scenario matrix

• valid: all checks pass.
• tampered-trace: fails trace verification.
• replay: fails challenge context and freshness checks.
• policy-mismatch: fails expected policy hash check.

Practical SEO and buyer relevance

Teams searching for terms like verifiable AI actions, non-repudiation for agent decisions, and policy-bound autonomous commerce can use this document as a boundary-level architecture reference before implementation.
