The rule may be correct and the comparison may look correct, yet the system can still make the wrong decision if different components interpret the same input differently.</p> <p>For example, one layer may treat two textual forms as equivalent while another treats them as different. A validator can approve one representation, then a later component can normalize or decode it into a different value before using it. The security check and the operation are no longer reasoning about the same thing.</p>
