Sam pointed out that Providers_Seen__c still contained additional provider signals such as Family Care, Raley, AllyMed, Dixie Chiropractic, and Clarksville Spine.
I ran a fourth targeted correction pass against live Litify. This pass used Providers_Seen__c as a supporting source only where the provider was specific, location-disambiguated, or supported by follow-up text, and where Current_Treatment_Plan__c did not appear to name a competing provider.
