The task

A Rust URL parsing workspace lives at /app. It exposes URL parsing, joining, serialization, path and host accessors, and public slicing positions. A parsed or joined URL should round-trip through serialization and parsing while preserving scheme, host, path, query, fragment, and slicing behavior. Fix non-special URLs with no host or authority whose logical path starts with //. When serializing that shape, insert the…

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.

Current evidence

Model / effort	Verifier result [95% Wilson]	Diagnostic labels / valid	HARNESS_ERROR · excluded	Outcome classes

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.
