 CURRENTLY DOING: 
 
+todo: Move back to original linked tax codes with hybrid history preservation system 
+	BACKEND:
+		- Tax codes 
+			are locked from edit all fields involved in calculations only (others ok like name etc)
+			 once they are selected anywhere and Active=false is prevented if they are a default for global or contract
+			Validation code must check before edit if in use in any final records like woitem* or contract or PO or Global sets
+			REcord must be sent to clietn with inuse flag set so ui can selectively allow or not edit fields to replicate server validation
+		- Service rates
+			Are locked from edit all fields involved in calculations only (others ok like name) once they are selected anywhere 	
+				validation must check before edit if used on contract, woitem*, anything that references them
+			REcord must be sent to clietn with inuse flag set so ui can selectively allow or not edit fields that would pass validation		
+			
+		- FORM FIELD DEFINITIONS 
+			Edit to remove fields and add manual override field back		
+
+		- Workorder
+			TAXES
+				remove all the code that preserves the tax info like name and values and move back to the single ID
+				update the calcs code to fetch the tax code to apply it
+
+				
+				put back the tax code viz field
+				update the FormFieldReference to remove the tax code shit
+
+			RATES
+				Rates are fixed now so no need to store redundantly except user can override so...?
+				How about a single override field that is null by default and if an entry is made that takes over from the default rate
+				To clear it they simply empty the field and if null the viz calcs will use the rate price instead
+
+			CALCS / VIZ
+				Calcs are now all Viz fields populated on the fly and not stored in the wo
+				Override field is used if non-null otherwise the rate is pulled and used for the calc
+
+	DOCS
+		Document rate locking (new for v8) and tax code locking (not new).			
+
+	FRONT:
+		Revert back to viz fields and remove snapshotted fields
+		switch back to simple picklist for taxes
+		Expose the override field
+
+
+	HYBRID - mostly fixed with a few things snapshotted that are likely to change regularly
+		Impermanent things: 
+			prices of things
+			addresses
 
-todo: Tax code decoupling from wo so can delete separately 
-	replace tax code drop down with a composite control instead that shows as text with an edit button when a taxname is set and just a dropdown when it's not set (null)
 
-todo: once settled needs to flow this back to the po and other tax code items.
-	change to composite control
