axioms for len(substr(...)) escaped due to nested rewriting
add simplification rule for at(x, offset) = "" Introducing j just postpones some rewrites that prevent useful simplifications. Z3 already uses common sub-expressions. The example highlights some opportunities for simplification, noteworthy at(..) = "". The example is solved in both versions after adding this simplification.

Z3Prover#7791 reports on using model values during lex optimization that break soft constraints. This is an artifact of using optimization where optimal values can be arbitrarily close to a rational. In a way it is by design, but we give the user now an option to control the starting point for epsilon when converting infinitesimals into rationals.
