Models & Harnesses Tested
Every harness and model XYZ has been evaluated with, from the committed harnesses registry. Full narratives live in the repo's HARNESS-MODELS-REGISTRY.md; benchmark artifacts in TESTS-RESULTS/.
Evaluated pairs — grades
| Harness | Model | Grade | Gate | Diff cleanliness /5 | Seam reliability /5 | Failure mode | Evals |
| commandcode | Qwen 3.8-Max | A- | ✓ passed | 5 | 5 | none | 24 |
| dsh | deepseek/deepseek-v4-pro | A | ✓ passed | 5 | 5 | none | 1 |
Grades come from the evaluations ledger: A-range means the pairing is production-usable as driven; B-range usable with caveats; C or N/A means not recommended for that pairing. “Evals” counts the individual verified invocations behind each row.
