2. **Scope Fit**: Is this within declared scope? Or is it scope creep disguised as enhancement?
3. **Constraint Compliance**: Does it violate any constraints (technical, resource, philosophical)?
4. **Strategic Value**: Is this solving the right problem? Or a distraction?
5. **Sprint Relevance**: Does it align with current sprint focus? If not, should it wait?
