The $201,600 Lean 4 proposal to formally verify Halo 2/Orchard was rejected on May 29, the same day Taylor Hornby disclosed the soundness bug. NU6.2 fixed the circuit, but the turnstile only bounds value leaving pools; it cannot retroactively prove every private note inside Orchard was clean. A second verified Orchard pool becomes a quarantine/migration market: stronger assurance, weaker anonymity set at launch, and a live test of whether ZEC users price proof quality over pool depth.
