Pareto Rail benchmark rollouts
Full agent transcripts for every published run of the Pareto Rail level-generation benchmark: models one-shot a browser rail-shooter level from a written theme, and visitors rank the results blind on the public site. The benchmark's methodology, per-run provenance manifests (rendered prompt, sealed commits, gate results, measured cost), and the level source produced by each of these transcripts live in the main repository: github.com/paulbatum/pareto-rail.
Layout
runs/<run-id>/assignment.md # the rendered prompt the agent received
runs/<run-id>/stages/<stage>/<harness>/rollout.jsonl # the harness-native session, opens in the trace viewer
runs/<run-id>/stages/<stage>/<harness>/events.jsonl.gz # the harness's emitted event stream
runs/<run-id>/stages/<stage>/<harness>/final-message.md # the agent's closing message
Each rollout.jsonl is a raw Claude Code, Codex, or Pi session file, so it opens directly in the Hub's agent trace viewer; assignment.md and final-message.md are plain markdown. Transcripts are exactly as captured: agent screenshots taken during the run are embedded as base64. rollouts.json here (also committed in the main repository under benchmark/manifests/) maps each run to its level, theme, and configuration and records the size and sha256 of every transcript's uncompressed bytes, so a download can be verified (after gunzip, for the gzipped event streams).
