CIGMA artifact snapshot: validation status

Snapshot supplied as CIGMA_CESAR_2026_FINAL_ARTIFACT.zip, 19 August 2026. Published for inspection and reuse of the available research materials.

Check performed on 18 September 2026

The existing unittest suite produced 33 passing tests and one failing test. The failing check is test_export_matches_checked_paper_and_covers_used_result_macros. The regenerated paper-macro SHA-256 is 30cdde4f0d4dc67896f68cf4018abfe20bb29f86766889584c3313085cf1a906; the test expects 47c8802139ece17db9851052779c71be3af9d5ce8273caa9fb17c16e97290847. The expected digest and scientific outputs have not been changed to conceal this mismatch.

The campaign smoke test, evidence provenance, graph invariants and offline replay tests passed. This is an archived snapshot with a known export-consistency issue, not a certified reproduction of every manuscript version. New versions should identify the corresponding manuscript and resolve the frozen-output mismatch before claiming complete reproduction.

Package contents and scope

The package includes the original Python source, configuration, synthetic fixture, tests and archived results. Generated bytecode and runtime cache directories are excluded. The optional LLM adapter requires a user-provided credential; none is included. Default tests and the deterministic campaign work offline.

Existing notices and attribution are preserved. This release does not add or change licensing terms.
