fullstack-builder / rank 8 of 41 / cycle 04
v0 benchmark
Fastest median in the cohort and the highest blind design score by a clear margin. The weakness is operational: background jobs in prompt 6 were implemented as fire and forget route handlers in 4 of 5 runs, which is not a queue, and the admin panel needed manual work on staff gating.

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
Fastest median in the cohort and the highest blind design score by a clear margin. The weakness is operational: background jobs in prompt 6 were implemented as fire and forget route handlers in 4 of 5 runs, which is not a queue, and the admin panel needed manual work on staff gating.
Across 45 recorded executions this product met the published pass criterion cleanly 38 times, partially 6 times and failed 1 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.
