swe-marathon-five-arm

# SWE-Marathon shared execution Read `../../runtime/RUNTIME.md` and `../../../runtime/RUNTIME.md` before preparing a new study. Use the shared Harbor adapter and its explicit execution_mode and iteration_context, preserving native tasks, verifier policy and scoring. The historical five-arm WEN framework is retired. Do not run its assisted unblock or sandbox-replacement wrappers, reinterpret withdrawn results, or invent an independent validator from git status. Existing study data and withdrawal notices remain tied to their original source revision. Validate the chosen native environment with a bounded task before a full run. Model jobs, verifier access and publication require the caller's authorization; loading this migration guide grants none of those actions.
