#62: Formal Verification of State Transitions under Concurrency (Kani)

Overview

Add formal verification proofs verifying that concurrent invocations of claim, submission, and cancellation handlers cannot cause double-spending or unauthorized escrow releases.

Objectives

• Write formal proof models using the Kani model checker.
• Verify absolute balance invariants under concurrent task actions.
• Identify and eliminate potential race conditions or state corruption.

Acceptance Criteria

• Kani verification harness implemented.
• Proofs validating correct state transition constraints.
• 0 issues or violations found during Kani validation runs.
