The task

Air-quality benzene alert system The file /app/environment/data/airqualitybenzene.csv contains 8991 chronological hourly readings from an Italian roadside air-quality station: hour, weather variables (T, RH, AH), same-hour metal-oxide gas responses (S1CO through S5O3), and C6H6, the certified benzene reference measurement. Rows with a present C6H6 value are training data; rows with a blank C6H6 are the held-out hour…

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.

Every recorded run

4 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.
