## Trait

**Hidden Grader**. A hidden check reads only the final state, so its hits ignore barriers and raised Proof. Receipt: `Relay@f50e9e097:README.md:63-64; README.md:220; scripts/check-workflow-graders.mjs`

## Moves

- Live Browser hits for 100, 95% of the time. Pick a model and a task, then watch every action it takes in a real browser. Receipt: `Relay@f50e9e097:README.md:70-72`
- Head To Head hits for 45 twice, 95% of the time. Two models run the same task from the same starting data in fresh workspaces, side by side, each graded separately. Receipt: `Relay@f50e9e097:README.md:94-97; src/live/duel.jsx`
- Action Menu hits for 80. An AI model picks one action from a menu of visible actions, and the panel shows the probability it gave each. Receipt: `Relay@f50e9e097:README.md:165-169; docs/system-one.md:13-17,26`
- Watch Replay sharpens its next hit. Any recorded run plays back in the real interface, step by step, with its dialogs, typed text and targets. Receipt: `Relay@f50e9e097:README.md:82-92`
