coding-agent / rank 24 of 41 / cycle 04
Emergent benchmark
Long autonomous runs that keep working without supervision, which is exactly what prompts 5 and 6 reward. It is the slowest median we recorded and the spread is wide: the gap between p10 and p90 is the largest in the cohort, so planning around its timings is hard.

The reader index is a weighted mean of reader submitted axis scores using the published index weights, renormalised over the axes readers have scored. It is never blended into the lab index. How this works.

What agent performance looked like in practice
Long autonomous runs that keep working without supervision, which is exactly what prompts 5 and 6 reward. It is the slowest median we recorded and the spread is wide: the gap between p10 and p90 is the largest in the cohort, so planning around its timings is hard.
Across 45 recorded executions this product met the published pass criterion cleanly 36 times, partially 3 times and failed 6 times. The rows above carry the reviewer note for every non clean outcome, which is the only way to tell a product that fails loudly from one that fails quietly.
