Caveats
Iteration "header-blue" is void: its check already passed before the prompt was sent, so it cannot measure this edit. Fix the check in the brief.
4 poll ticks were skipped because a capture overran the interval.
judge: openai:gpt-5.5 does not accept a sampling temperature, so these frames were scored at the provider's default rather than at 0. Two runs of the same page can be scored differently, and that variance is inside the AUC. result.json records the temperature as null rather than as the value that was asked for, so p2p compare will not pool this run with one that was scored at a fixed temperature.
