Pega Platform™ provides a set of guardrails that promote best practices for application design and implementation. Guardrails guide development to optimize reuse, maintainability, and system performance. Severe and moderate warnings are now more visible in the rule. If you attempt to save a rule that has one or more severe or moderate warnings, the rule header displays the warnings.

You must justify moderate and severe warnings when you check in a rule. If you attempt to check in a rule with moderate or severe warnings, the justification field is marked as required. Even if the warning is justified, the header displays the error header to indicate that this rule still has technical debt.
