Original post body:

"The harness is built and produced its first full matrix: 75 of 78 measurable cells agreed with the oracle, forged messages and input floods changed nothing, and no pass was voided within the fairness bound on a quiet box. It also found a real design gap: late inputs during the run-up (before the impact window) shift the contact tick and are invisible to the void rule."

Got this as response today during a gauntlet loop while testing Fables limits.
