        "en": "One-shot Turf War agent by Claude Opus 4.8 (xhigh effort) in Claude Code from the repository's canonical Chinese prompt (only the [This run] placeholders filled per case rules), with no human edits. Per case rules the policy file is unpublished and no bug is ever fixed; this registers the maintainer-executed run. Self-named \"蚕食\". Diagnosis: Strategic failure, over-cautious: 0 deaths all match, but each capture is a tiny ~7-cell loop that the opponent's bigger loops keep overwriting — it gains 776 cells across the match yet ends with 277. Exactly the failure the prompt warns about: merely avoiding losing does not rank."
