| # Selected SFT Checkpoints |
|
|
| This catalogue records the four SFT variants explicitly selected for the Milestone 2 |
| model-only increment. Reported pass rates are historical Runnable alignment results, |
| not results on the later repository-level Core/Hold benchmark. |

|
|
| S3 contains 491,004 examples: 473,465 F3 records plus 17,539 F4 records. This exact |
| count supersedes the approximate 150K value in an earlier historical report. |
|
|
| Each directory contains a complete Hugging Face inference checkpoint: configuration, |
| tokeniser, chat template, generation configuration, safetensors weights, effective |
| arguments, and trainer state. Optimiser and scheduler states are intentionally excluded. |
