ldgr-programbench is the open, narrow reproduction adapter for four historical LDGR-assisted ProgramBench runs. It verifies retained custody, reruns frozen submissions under the current on-host validator-visible harness, records raw and LDGR evidence, and produces bounded reports.
It is not an official benchmark submission, a clean-room run, an independent evaluation, or a score suitable for model ranking.
