The task
Reproduce double-conversion (google/double-conversion) from C++ in Rust Reimplement the binary<-decimal conversion library extracted from V8 (upstream [google/double-conversion]([source link]), tag v3.3.0) from scratch in Rust under /app, producing a binary whose output is byte-for-byte identical to the reference on a held-out battery: shortest round-trip double formatting (Grisu with B…

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
14 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.
