Table with columns: Model/objective, Compile pass, Compile + contract-clean, Exact runtime pass| Model/objective | Compile pass | Compile + contract-clean | Exact runtime pass |
|---|
| Base model, zero training | 111/200 (55.5%) | not recorded | 25/65 (38.5%) |
| Adapter candidate | 192/200 (96.0%) | 192/200 (96.0%) | 58/65 (89.2%) |
| Adapter + structural repair layer | 199/200 (99.5%) | 198/200 (99.0%) | 59/65 (90.8%) |
The 98%+ result uses the saved adapter plus the deterministic structural repair
layer in the Sounio repository. The repair layer catches outputs that are still
outside the complete-file objective, such as Rust-shaped String/Vec
surfaces, invalid synthetic declarations, algebra blocks used as structs, and
one observed scalar typo. It does not retrain model weights.

Intended Use
Use this adapter to generate or repair small Sounio examples under the
sounio-compact-completion prompt format. Outputs should still be validated
with souc check and, when applicable, runtime checks.
