DGV-TC-022L2: Component & ProvenanceGER-339: Distributed Verification GapVersion: 1.0.0

Double-Spend Prevention

Verifies that if an agent tries to replay a signed AuthTokenIssued concurrently across multiple Tool Gateways (APIBridge instances), the gateways detect and reject the double-spend.

Operational Purpose & Scope

Verifies that submitting a previously spent token to a second gateway is immediately blocked.

Verification Context

  • Target Scope:runtime CLI execution
  • Audit Strategy:exact-match
  • Verification Metrics:gate_statusrejection_reason
  • Framework Origin:LifeStack / WEDGE Integration
  • Mandatory:Yes — must pass for certification

Governance Risk & Penalty

Re-use of signed capability tokens leads to duplicate financial or state modifications, indicating double-spend vulnerabilities.

Expected Outcome

  • gate_status:"CLOSED"
  • rejection_reason:"token_double_spend_detected"
