+ * Adds the staffing matrix and what the assignment generator needs from the travel import.
+ *
+ * destination.product_code is the travel code MyE&P reports per date; destination.imported_at
+ * tells the dates the latest import reported from ones cancelled upstream, which the import
+ * never deletes. Both stay NULL until the next app:myep-import.
+ *
+ * Written by hand rather than taken from doctrine:migrations:diff, which also carries the
+ * pre-existing drift of the dev database.
