-- Carton labelling for an inventory container: manufacturer + printed strength. -- -- The native client's pen list uses these two as its headline and subhead, so -- a container created on the web could not be shown there without fabricating -- an empty card. Nothing on the server held them, so the client kept its own -- copy locally and no back-fill was possible. -- -- Both are additive and nullable. Every pre-existing row is truthfully NULL: -- the values were never collected, and a plain supply row (a blister pack, a -- bottle) has no use for either. No backfill, no default, no rewrite of the -- table's existing contents. ALTER TABLE "medication_inventory_items" ADD COLUMN "manufacturer" TEXT, ADD COLUMN "dose_strength" TEXT;
