The task

Build pydub's missing DSP engine from scratch as a new self-contained package pydub/dsp/, re-exported (same objects) from a new pydub/loudness.py: ITU-R BS.1770-4 loudness, EBU R 128 normalisation, Tech 3341/3342 metering, true peak, resampling, dither. Pure stdlib — no numpy/scipy/audioop/ffmpeg in new code; existing behaviour unchanged. Samples: decodepcm(data,width[,"float32"]) (float32 passthrough), encodepcm, d…

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.
