Fable
The caravan finally standardized the openings of its compressed grain sacks
In the early years, the mountain-road caravan transported grain very simply. Each mill used its own sacks, with different openings, labels and weight marks—since the routes were short, any problem could be traced back and asked about. Later, grain had to be delivered to distant villages, and many villages had only small warehouses and hand-cranked mills. If the sacks couldn't be opened or the labels couldn't be read, the grain was unusable no matter how good it was. The shopkeeper first required every village to learn each mill's sack method. The villagers memorized a wall of mnemonics, yet still often mistook fine flour for coarse and old sacks for new.
He then had the cart driver repack the sacks along the way. This made things worse—the road was windy and rainy, and each repacking added another chance for mix-ups and spilled grain.
A guild clerk proposed standardizing sack openings and labels. Bags had to state the grain type, grind coarseness, recipe notes, opening method, and which hand mill they were for, and the old bag conventions gradually gave way to the new format.
The mill at first found it troublesome. The scribe asked only one question: if the village cannot be opened reliably, then no matter how valuable the grain looks on paper, it is just weight pressing down on the cart.
After the unified format was promoted, the same batch of grain could be read by small mills in different villages. Some chose coarser compression to save space, others chose a finer version for taste, but the bag's reading method was consistent.
The caravan finally discovered that for compressed ration packs to circulate, it took not just the compression itself but also a file convention that let the runtime understand them reliably.
The clerk also required that the bag opening bear the mill name, sealing date, and verification stamp. If a village opened a bag and found the grain flour caked, it could be traced to which mill, which batch of millstones, and which pressing method had gone wrong.
Later, a mountain road was washed out by rain, and the caravan temporarily took another route. The new village had never seen these mills, yet it opened the sacks smoothly according to the unified sack mouth. Only then did the shopkeeper believe that the value of the format was not in neat paper, but in still being reliably taken over by others after leaving the original workshop. The unified sack method allowed small warehouses to judge whether a grain sack could be handled by their own hand mill without knowing every mill. The sacks were lighter and the roads longer, so the convention for reading sacks became even more important than before. From then on the shopkeeper inspected the sack first, and only then praised the grain.
