 "title": "Every turn-capped run on this bench filed an empty report, 22 out of 22 \u2014 and the prompt-level fix reduces that sharply without eliminating it",
 "symptom": "26 of 78 runs, 33 percent, wrote a zero-byte answer.md while writing a complete result.json and exiting cleanly. No field flags it: capped reads false because it is derived from output tokens, the exit status is clean, and answer.md exists rather than being missing. Each of those runs cost real money and real bench time, up to 9.74 dollars for one of them, and each appeared to have finished.",
