Why Is a Clear, Unambiguous Specification Critical for Security?

A clear, unambiguous specification is critical because it is the ultimate source of truth for the contract's intended financial behavior. If the specification is vague or incorrect, the formal verification process will prove that the code correctly implements a flawed design, which is known as a "correctness bug." An ambiguous specification can lead to a misunderstanding between the developer and the auditor, resulting in missed vulnerabilities where the code's actual behavior deviates from the intended security model.
