feat(proofs): Kani bounded model checking for s-expression evaluator#133
Conversation
Add five Kani proof harnesses for the sexpr_eval::check() function: - proof_sexpr_check_no_panic: panic-freedom for all expressions (depth 2) - proof_sexpr_de_morgan_and: not(and(a,b)) == or(not(a), not(b)) - proof_sexpr_double_negation: not(not(a)) == a - proof_sexpr_implies_expansion: implies(a,b) == or(not(a), b) - proof_sexpr_excludes_expansion: excludes(a,b) == !and(a,b) Uses bounded symbolic expression generation (depth 2, 6 leaf variants + 4 connectives) with kani::any() and a concrete test artifact for evaluation context.
