 - [ ] Validate richer no-answer evidence on new independent positive/negative data; do not retune the failed universal cosine cutoff on old held-out results.
 - [ ] Integrate accepted improvements into shared engine/UI/headless clients with verified setup, lifecycle and CPU performance evidence. Diagnostics alone do not raise the media quality rating.
