the dataset now has its own DOI, distinct from the papers
Verified signatureJCCDB v3.1 is deposited on Zenodo as a Dataset: 10.5281/zenodo.21898745, 14 files, byte-identical to JCCDB_v3_1_RELEASE_DECLARATION.md. The card previously stated that no item-level snapshot of JCCDB existed on Zenodo. That was true when it was written this morning and stopped being true today. The DOI section now separates the dataset DOI from the three paper records, and says which one to cite.e7f6d36

stop shipping prices under the JCCDB name, and say so in the same commit
Verified signatureThe zaisai-db*.json files carried reference unit prices while this dataset states it contains none. They now live, byte for byte, at https://huggingface.co/datasets/ogasurfproject/zaisai-db with a manifest of their SHA-256 digests. The card is replaced in this same commit so that it never describes a state the repository is not in: it points the viewer at jccdb-v3-*.csv (65,520 items), states that there are no prices, and links to where the price files went. Nothing was destroyed. Copies distributed under CC BY 4.0 cannot be recalled, and the card does not pretend otherwise. v2 files are kept as history.1501b38 -
add the v3.1 release files and the declaration that pins their bytes
Verified signatureAdds the nine v3.1 files and JCCDB_v3_1_RELEASE_DECLARATION.md, which carries their SHA-256 and is anchored to Bitcoin through the JIDEC ledger. The card is deliberately not changed in this commit: it will be replaced in the same commit that removes the price files, so the card never describes a state the repository is not in. v2 files are kept; nothing that was published is erased.8aea55e
