Compare this with how Ada/SPARK handles contracts. In SPARK, contracts are verified statically by a formal proof engine using SMT solvers (CVC4/Z3). The toolchain proves, at compile time, that preconditions are always satisfied by all callers. If it can’t prove it, the code doesn’t pass review. There’s no “observe and continue” — you fix the proof or you don’t ship. C++ contracts are runtime checks with optional enforcement. SPARK contracts are compile-time proofs with mandatory satisfaction. These aren’t the same category of tool.
