IVy is a research tool intended to allow interactive development of protocols and their proofs of correctness and to provide a platform for developing and experimenting with automated proof techniques. In particular, IVy provides interactive visualization of automated proofs, and supports a use model in which the human protocol designer and the automated tool interact to expose errors and prove correctness.

@gipsyh this is not really a bug. Try:

#lang ivy1.7

object foo = {
    relation bit
    after init {
        bit := false
    }
}
