selling to negative on hand creates havoc with your accounting data, COGS and Asset valuations.

No it does not.  When you sell to a negative, asset value is lowered by the present average cost and posts to COGS
that value might not be right when you buy replacement stock, but at that moment there in no havoc with your accounting.  AND when you do buy replacement stock for an item sold to a negative on hand, QB makes the adjustment to both inventory asset and COGS if average cost did change.

 If you sell an Assembly item and then Build it later, you need to Date the build on or before the sale.

No.  An assembly item will not build at an earlier date if there is no qty on hand, you can NOT order items now and build before that receive date.
