The Tuesday loaf
A bakery near the harbor keeps a small shelf of suspended bread. A regular customer, buying her own loaf, taps “add one to the shelf.” That evening someone shows a code at the counter and walks out with warm bread — no form, no questions, no eye contact required. The baker never learns who; the customer never learns who. The map just quietly ticked down by one.
Protocol shown: In-store customer suspension → open-shelf fulfillment → zero exposure.
