What

Documents Phase 3 (SWE-bench Verified eval) for the Gemma4-31B CoderForge CP-SFT recipe, and adds the OpenHands-3-tool eval scripts it references.

  • README Phase 3: scaffold, the run→grade commands, and the base-vs-SFT result.
  • eval/: the 5 scripts the pipeline actually uses (setup, prewarm, serve+agent, grade) + the tool-call-emergence probe (oh3_run.py, enroot_env.py, grade_enroot.py, prewarm_images.py, probe_indist.py, and their .sub/.sh launchers).

Result

CoderForge SFT installs agentic behavior into the raw base google/gemma-4-31B: the base emits 0/33 tool calls (never_toolcalled); the SFT model emits structured tool_calls (think/execute_bash/str_replace_editor) on every turn.

Validation

Ran the documented pipeline end-to-end on the step_799 checkpoint: setup ✓, serve+agent ✓ (vLLM served, 21/21 structured tool calls), grade ✓ (runs clean, enroot-errs 0). Scripts sanitized for public use (/path/to + <account> placeholders, NVIDIA headers); ruff check/format clean. Docs-only; no library code changed.
