nickelate.sc: Vol. 1, No. 1 — Bilayer nickelate screening corpus

A pseudonymous, manually curated screening notebook over the published bilayer-nickelate superconductivity literature. Includes 23 measurements (ambient films, films under applied pressure, bulk under pressure), a 22-gate physical/control/evidence schema, gap candidates derived as Hamming-distance neighbors of measured anchors, negative results, and a weekly arXiv watcher. Distances and ranks are retrieval scores, not probability estimates of Tc. Nearest-neighbor anchor Tc values surfaced for each gap candidate are values measured on the anchor, not forecasts for the candidate. Cite the primary literature (linked in each record's source_doi field) for any scientific claim. See docs/inclusion_criteria.md, docs/gate_definitions.md, docs/ranking_method.md, and AUDIT.md for the full schema, criteria, and known limitations.
