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.
