Salesforce object-model governance
It takes forty seconds to change what a field means. Make the meaning governed.
Import your describe export and govern the object model itself: active picklists become Taxonomies (the governed value set is the only control where the platform does not enforce one), lookups become governed references, and every audit flags picklist-unrestricted, field-no-help and polymorphic-reference findings against the governed model.
