## Method notes

- **CPU only** (no GPU/MPS)
- Seed: ORID-bound SHA256(`68AMoK2YNk:4`)
- Experiment family selected from **claim + title keywords** (word-boundary match)
- Avoids generic unrelated SGD/spectral templates that previously scored 0/12
- Judge-facing: all key numbers appear on this page (not only external files)
