s_4 (agreed) 5b97ccf802c7…56573302957f
s_5 (operator claim) f48be38fcdf7…3b7ebcf795fc
Operator must reveal preimage p with SHA256(p) = claimed s_5. If no such preimage exists, the Taproot defense leaf is unsatisfiable and the slash leaf wins after the defense window.

Operator
79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798

Publishes the state commitment. Must defend the disputed step by revealing a valid preimage during the defense window.

Challenger
c6047f9441ed7d6d3045406e95c07cd85c778e4b8cef3ca7abac09b95c709ee5

Independently recomputes the trace and disputes the operator's claim. Sweeps the bond via the slash leaf if defense fails.

Disclaimer

This terminal demonstrates Axion's Bitcoin-anchored dispute lifecycle on Signet. Some contract timing is simplified for MVP purposes: the dispute contract is currently parameterized after bisection converges. Production BitVM-style enforcement will require pre-signed transaction trees and connector outputs to lock the bond at commitment time and carry the dispute through to settlement without operator coordination.
