Finished computing initial states: 1 distinct state generated at 2026-08-07 20:57:56.
Progress(3) at 2026-08-07 20:57:56: 4 states generated, 3 distinct states found, 0 states left on queue.
Checking temporal properties for the complete state space with 3 total distinct states at (2026-08-07 20:57:56)
Error: Temporal property Live was violated.

Error: The following behavior constitutes a counter-example:

State 1: <Initial predicate>
x = 0

State 2: <Next line 5, col 9 to line 5, col 24 of module Lasso>
x = 1

State 3: <Next line 5, col 9 to line 5, col 24 of module Lasso>
x = 2

Back to state 1: <Next line 5, col 9 to line 5, col 24 of module Lasso>
