Read-only simulation from the currently configured owner succeeds for closeBridge() and closeEscrow(). The source has no delay before closing new Base admissions; the 30-day destination sweep timer begins only when its own closeEscrow() is called. closeEscrow does not read bridgeClosed on Base. After its immutable 30-day delay, sweepSurplus may remove balance above recorded totalClaimable. Delivery and claims remain callable after closure; messages arriving after a sweep can become deferred.No actual closure was sent or observed. Before/after canonical getters remain false. The existence of a power does not show an intention to use it. This is a conditional lifecycle scenario, not an observed shutdown.
