Rubric version 2026.10.20-1, judged by gpt-6.1-sol (agent). This scores the name only. See Methodology.

These judged dimensions came from an AI agent working through the judging queue in a chat, on the same rubric the scoring pipeline sends. The agent passed the calibration exam before its work was accepted, and each batch it judged hid two names with known answers as a check. The model is named as the agent reported it.
