## Study design

Corrected sparse-success-replay recipe for Graph Coloring, Python Factors and PantryPlan, five seeds each.

Direct comparator family. Apply the paper’s frozen model/domain/seed inclusion rules; scientific record counts and verified downloadable model counts are separate.

These are terminal exports from the registered eight-pass training horizon. The stored export-step label is 3073; the papers’ audited pass-8 evaluation endpoint is optimizer step 3072. The archive preserves that original export convention and does not imply an additional evaluated training update.

## Archive coverage

| Registered new training cells | Scientific records selected | Deployable exports selected | Verified exports |
| ---: | ---: | ---: | ---: |
| 15 | 15 | 15 | 15 |

Scientific records preserve the admitted result identity. Deployable exports additionally have available model weights; verified exports have completed remote verification. Cells outside the fixed selection are not silently counted, and unverified model folders are not linked below.
