 This dataset is intended for use with the [hermes-agent](https://github.com/NousResearch/hermes-agent) Solidity Eval environment, but the `workspace_tar` / `scoring_tar` shape is harness-agnostic — any agent harness that can stage a tarball into `/work` and run a scorer over `/scoring` can use it.

Reference sandbox image extended with Claude Code per the Dockerfile snippet above. Wall-clock ~34 min on a 32-core host.

+A non-trivial fraction of failures on `lite` come from B3 canary false-positives where the deleted function legitimately requires common Solidity primitives (`keccak256`, `encodePacked`, addresses unsorted via `sortTokens`, etc.). The ground-truth canary list is generated by token-overlap with the deleted function body and was not pruned for these false-positives in the v0 build; this is the dominant source of noise on the `lite` baseline. Filter to rows where the canary set excludes those tokens if you want a less-noisy slice.
