The task

Predict how many helpful votes each Health and Household product review will earn, and report how confident you are in each prediction. The training reviews live in [local evidence] as one gzipped JSON-lines file per year named healthandhouseholdreviewstrain<year.jsonl.gz, each row carrying its helpfulvotes; load and concatenate them all. The reviews to score are in [local evidence] with t…

Results by model and effort

This exact task version only. Every rate is passes / valid runs with a Wilson 95% interval; n≤2 remains counts only. Macro aggregation does not apply within a single task. Baselines are summarized in the quality gates, not ranked. A passed no-op resistance check means that doing nothing did not solve the task.

Difficulty, with uncertainty

Selected-best difficulty: 66.7% [35.4%, 87.9%]. This is one minus the best measured current-row pass rate among rows with at least five valid runs.

The maximum is selected from the observed rows, so the estimate is optimistic. Its Wilson interval is not adjusted for model selection. “Hard” requires qualifying GOOD_FAILURE evidence; the threshold flag additionally requires the interval and recorded quality gates to meet the documented rule. This is not independent validation. Threshold flag: no.

Every recorded run

14 recorded trials, including controls. Diagnostic labels do not replace verifier reward. Labels and quality checks are source declarations, not independently attested here. Internal evidence remains private; a missing public URL is shown explicitly. Records with invalid or absent rewards are not scored.
