## Post-Audit Vulnerability Regression

Post-Audit Vulnerability Regression occurs when new security flaws are inadvertently introduced into a codebase during the process of fixing previously identified issues. When developers modify code to remediate an audit finding, they may disrupt existing logic, break dependencies, or open new entry points for exploits.

This phenomenon is a significant concern in complex systems like cross-chain bridges or synthetic asset platforms. It necessitates a rigorous testing cycle, including regression testing and re-auditing, to ensure that the fix does not negatively impact the broader system.

This is a critical aspect of systems risk, as a simple patch can sometimes trigger a cascading failure if not carefully integrated. Effective management of this risk requires modular architecture and comprehensive test suites that validate the entire system state after every change.

It underscores the danger of assuming that a fix is inherently safer than the original code.
