+Guarantee 1 states that price sources will never change prices on their own.
+Further testing in the wild has shown that this is desirable within a record,
+but not when copying items from one record to another within a workflow.
+
+Specifically when changing from sales to purchase records prices don't make
+sense anymore. The guarantees should be updated to reflect this and
+transposition guidelines should be documented.

+
+Prices were originally planned as a context element rather than a modal popup.
+It would be great to have this now with better framework.
