Fable
The print shop's ink paste distinguished original drafts, copies, and revisions
The painting workshop in the south of the city made signboards for shops. At first there was only one painter, and drafts, finished works, and revisions all sat on the same table, so the shopkeeper could tell at a glance where each piece came from.
Later, the painting workshop hired copyists, colorists, and out-of-town woodblock carvers, and began citing old painting albums. The signboard was made faster and faster, but the table was piled with papers whose origins could not be identified.
The shopkeeper first had everyone sign in the corner of the painting. But a painting might first be copied from an old work, then colored by two people, and finally have its lines altered by a woodblock carver. A single name in the corner only showed who touched it last.
An apothecary shop owner discovered that his signboard used a prohibited pattern and traced its source. The painting workshop searched every desk and found only three similar drafts, with no evidence showing which was the original, which was a copy, and which had been altered by whom.
The shopkeeper then stamped every sheet with its source: original commission, reference album, external material, modifier, modification time, conversion method, and scope of authorization, all traveling with the painting. Any derivative draft had to carry its parent draft number.
When disputes arose again, the painting studio could trace the seal ink to a pattern from an old album, and that album allowed learning only, not commercial use. The problem was not that the colorist was careless, but that material licensing had not entered the production process.
From then on, when the painting studio delivered signage it not only delivered the image, but also a source statement. Clients knew which elements were original, which came from licensed materials, and which had been adapted.
The shopkeeper understood that content looking correct was not enough. Provenance lets data and content enter the system with their origin, author, license, and transformation history; otherwise, the faster the office assistant generates, the faster risk spreads. Later, another even trickier job came. On the surface it looked like just an amplified old problem, but in fact it forced out all the gaps hidden in the process: who takes over first, who can make changes, and how to return to the previous step when something goes wrong. Places that used to get by on acquaintances' tacit understanding now all had to be made clear. The person in charge did not urge everyone to be more careful again; instead, he walked the site again. He had people record every handoff, every failure, and every remedy—which places were merely slow, which places would harm the results, and which places would be hard to trace back once wrong.
