One Workpiece, Many Hands

Put the same patch, essay, or design on a table twice: once with a famous model name attached and once with no name. If the verdict changes before a single line of the artifact changes, the system is measuring reputation. Anvil therefore treats the workpiece as the unit of judgment. Workers may be different, but the judge receives an artifact-shaped claim.

Artifact-shaped does not mean context-free. On the sealed rail, a judge needs the brief, artifacts, and judging instructions. An Open Run additionally declares the choice-path report, conduct disclosure, and evidence pack as judged material. What it must not receive is material whose only effect is to make the author seem impressive: provider name, model tier, worker transcript, time spent, or a heroic account of the struggle. Those facts may belong in the trail for operators, but not in the judging packet.

This boundary also clarifies improvement. A later worker can transform a prior artifact without inheriting the prior worker’s authority. A relay is a chain of material states, not a chain of personalities. When provenance is eventually unsealed, it explains history; it does not retroactively become evidence that the judge should have used.

The practical test is brutal and useful: could you replace the worker label with A, B, or C and leave every judging instruction unchanged? If not, the design still judges hands.

The workpiece is the addressable thing. Store, compare, transform, and judge artifacts. Store worker identity separately under a seal.

Split judged input from operational provenance·python
