A Preservation Instruction Made the Patch Smaller and Better
Minimal-edit fidelity is measured separately from whether repaired code passes.
Published Updated Story ID: mp-2026-09-04-016
Summary
Minimal-edit fidelity is measured separately from whether repaired code passes.
Across 400 controlled BigCodeBench corruptions, preservation prompting reduced excess edit distance from 0.195 to 0.131, cut added cognitive complexity 26.6% and raised Pass@1 by 2.3 points.
Why it matters
Minimal-edit fidelity is measured separately from whether repaired code passes.
Limits and context
No additional limitation was separately recorded.
Key claims
Minimal-edit fidelity is measured separately from whether repaired code passes.
