How does the Sharing Permission work

who (R1, GoldFinc) do what

Where (GoldFinch) (GF_ObjectTriggerHandler, GF_Object_SharingHelper)

(R1) (B2B_orderTriggerHandler, B2B_SharingHelper)

How

GF_ObjectTriggerHandler: GF_Object_SharingHelper.insertItemJournalSharingRecords

GF_Object_SharingHelper: (GFERP__Item_Journal__c itemJournal : itemJournalList) {
            if (pantryToAssociationMap.containsKey(whsePantryManagerIdMap.get(itemJournal.GFERP__To_Warehouse__c))) {
                for (B2B_PantryAssociation__c pa : pantryToAssociationMap.get(whsePantryManagerIdMap.get(itemJournal.GFERP__To_Warehouse__c))) {
                    GFERP__Item_Journal__Share itemJournalShare = new GFERP__Item_Journal__Share(
                            ParentId = itemJournal.Id,
                            UserOrGroupId = pa.Pantry_Manager__c,
                            AccessLevel = 'EDIT'

B2B_orderTriggerHandler: if(!pantryIds.isEmpty()){
                for(B2B_PantryAssociation__c pantryAssociation : [SELECT Id, Name, Pantry__c, Pantry_Manager__c FROM B2B_PantryAssociation__c 
                                                                            where Pantry__c IN: pantryIds]){
                    if(pantryAssociation.Pantry__c != null){
                        if(pantryAndPantryManagerMap.containsKey(pantryAssociation.Pantry__c)){
                            pantryAndPantryManagerMap.get(pantryAssociation.Pantry__c).add(pantryAssociation.Pantry_Manager__c);
                        }
                        else{
                            pantryAndPantryManagerMap.put(pantryAssociation.Pantry__c,new Set<String>{pantryAssociation.Pantry_Manager__c});
                        }

B2B_SharingHelper:

 if(pantryToAssociationMap.containsKey(bg.Pantry__c))
            {
                for(B2B_PantryAssociation__c pa:pantryToAssociationMap.get(bg.Pantry__c))
                {
                    BuyerGroupShare bgs=new BuyerGroupShare();
                    bgs.ParentId=bg.Id;
                    bgs.UserOrGroupId=pa.Pantry_Manager__c;
                    bgs.AccessLevel='READ';
                    bgShare.add(bgs);

When

SKU disappeared?

did the R1 hourly routine overwrite sharing permission?

Possible to write an hourly routine to resync?????
