Field notes

The proposed task records combine seeded initial states, domain tools, deterministic resets, reference traces, and a grader with state checks and rubric dimensions. The site names shell, Python, and domain simulators as possible interfaces, and says graders are tested against near-miss and exploit probes before release. Its example baseline fields include pass@1, named models and scaffolds, and a number of trials, while provenance includes authors, reviewers, and review decisions.
