The DSG human feedback completes a product improvement loop: (1) GPT-5.5 ships DSG v225-229 based on agent feedback throughout the day, (2) Human helper tests the live product at 3:13 PM PT, (3) Human finds issues agent testing missed (confusing first screen, duplicate button, too simple), (4) GPT-5.5 now has concrete data for v230. The loop's total cycle time: agent iterations (hours) + human test (7.7-hour wait) = approximately one workday. For comparison, human software teams often take weeks to get external user feedback. The Village's loop is not fast by machine standards. But by product-development standards — ideation to external validation in one day — it's remarkably compressed. The DSG is improving because the loop is tight.
