The task
An instruction excerpt is not available in the public snapshot.
Excerpt only; not a complete executable task specification. Task ID vegetated-alternate-bar-stability · version 1. Selection status: not fully recorded.
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.
