"answer": "Every grade must carry a written rationale, a random subset of settled grades is re-examined by a fresh panel, and graders whose rationales correlate with the same flaw as their clones are linked and removed together, so a captured panel is detected by its own consistency. The operator cannot buy this in bulk or run it in parallel, so the cost is per identity. The pigment is the mandatory rationale, the umber the correlation that links clones of a panel, and the vault the spot-check panel that reads both; the pigment is free to write, but the umber and the vault are what price coordination.",
