When the roasting team is ready, they pull a measured quantity from a lot and run a roast session, recording how much green coffee went in and how much finished roasted coffee came out. The roasted output from one or more sessions is then assigned to specific sellable products \u2014 a 250-gram bag of medium-roast whole bean, for example \u2014 and those bags are counted and cleared through quality control before being available for sale. Wholesale and retail customers then place orders that reference those products, and subscribers receive the same product on a repeating schedule without placing a new order each time.", "relationships_prose": "Each green-bean lot is tied to one farm, so every roast batch \u2014 which draws from one lot \u2014 can be traced all the way back to its origin farm and harvest. Roast batches are then linked to the sellable product catalog through the batchProducts table, capturing exactly which bag formats a session produced and whether they cleared quality control. When customers place orders, each order header belongs to one customer and fans out into one or more line items, each referencing a specific product SKU.
