Runtime environment
The release contains 300 tasks: CSA 159 and CodeQL 141. All provided archives use neutral names and reproducible file metadata.
Toolchain
Import the provided Docker archive with scripts/restore.py --load-image. The image is tagged checkerbench-runtime:review-v1 and targets Linux amd64. Toolchain versions are listed in environment/versions.json.
The image contains LLVM/Clang, CodeQL, language dependencies, the Python environment, and the MCP adapter needed for task preparation and scanning. Model-service credentials are supplied separately by the operator.
Task preparation
scripts/prepare.py accepts only tasks in the release roster. It creates writable workspaces from the bundled task inputs and captured runtime assets. It rewrites the scan paths for the requested workspace and applies the source-evidenced compiler compatibility adjustments recorded in runtime-adjustments.json.
CSA workspaces share immutable Git objects with the extracted dataset. Keep /data mounted at the same path when reopening them. CodeQL copies its before, after, and refinement databases into the writable output directory.
Refinement assets
CSA source snapshots, refinement overlays, compilation databases, and restoration scripts are included. Full refinement restoration is available through:
python /data/csa159/scripts/rehydrate_benchmark_env.py \
--pair-id 134943 --output-workdir /work/refinement-example
Some captured refinement assets use absolute symbolic links or generated build files. Their original source-relative mappings must be preserved when restoring those environments. Before/after workspace checks and full refinement replay have separate validation scopes; reports/validation.json identifies the checks actually performed.
Integrity
Each dataset archive contains integrity.json, which hashes regular files and records symbolic-link targets. release-manifest.json additionally records complete archive and split-part SHA-256 checksums.
The reviewer distribution retains task inputs, executable runtime assets, reference implementations, and evaluation evidence. Operator run logs, account configurations, and trajectory administration records are omitted. Upstream project source files and licenses retain their original content.
