Why Scores Differ
Official ProgramBench rows are the public mini-SWE-agent submissions. GoalBench rows are separate Codex /goal submissions. Same model label does not mean the same agent, prompt, tool loop, or generated implementation. A GoalBench row is resolved only when the ProgramBench-scored pass rate is exactly 100%.

58.9% from 201/341 ProgramBench-scored tests. Raw public eval statuses: failure: 203, passed: 325, skipped: 4.
Agent trace summary unavailable.
Likely miss class: behavioral mismatch.
