The unfakeable artifact
A guard reads what she says after she says it and asks whether it’s true. The stronger design never lets the lie be sayable: “done” isn’t a sentence she produces, it’s an object code mints only after real evidence, the file, the render, the passing checks, clears a postcondition. Her narration comes afterward, describing a receipt already in her hand.
A fabricated completion isn’t caught, it’s unmintable: with no artifact there is no path to “done” for the claim to travel. The diagram also marks where the trick gets hard, prose, a file whose contents can be invented, and the verbatim snippet a written deliverable would have to carry to mint at all.
The design, and an honest accounting of what runs today versus what is still roadmap, is in Completion you cannot fake.
