Abstract
We study a problem where a new, unfamiliar group of agents has to decide how a joint reward should be shared among them. We focus on settings where the share that each agent receives depends on the evaluations of its peers concerning that agent's contribution to the group. We introduce a mechanism to elicit and aggregate evaluations as well as for determining agents' shares. The intuition behind the proposed mechanism is that each agent has its expected share maximized to the extent that it is well evaluated by its peers and that it is truthfully reporting its evaluations. For promoting truthfulness, the proposed mechanism uses a peer-prediction method built on strictly proper scoring rules. Under the assumption that agents are Bayesian decision makers, we show that our mechanism is incentive compatible and budget balanced. We also provide sufficient conditions under which the proposed mechanism is individually rational, resistant to some kinds of collusion, and fair.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
