Frozen Source-Scheduled Confirmation Runtime

These files are byte-for-byte copies of the implementation admitted by raw 260k confirmation job 689542, which started on Newton at 2026-07-15T04:47:26-04:00.

The live repository changed train/model.py after that job started to add masked-loss and resume-contract guards. The independent assessor therefore must not rehash the moving live path. It rehashes this directory instead.

The four non-loader files match the admitted local and Newton sources. The loader was copied directly from Newton while job 689542 was still running and its hash matched the value recorded by the evaluator. This archive does not replace or execute as the current training implementation.
