The task

The project in /app is a JavaScript bundler written in Go. When it lowers async generator syntax for older targets, the transformed program should preserve native async generator behavior. Calling next, throw, or return on an async generator before earlier iterator method promises have settled must behave like native JavaScript. The first call should start synchronously up to the first await or yield point, later ca…

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

5 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.
