EV424 Reproducibility Surface Preflight Receipt for the GW250114 Public Data Release

This record contains EV424-generated verification metadata and receipts for the public reproducibility surface of the GW250114 companion data release. EV424’s purpose is to bind integrity, reproducibility, and non-custodial verification into a recheckable trail. In this v0.1.0 record, EV424 verified:- official public record metadata- README checksum- public analysis bundle size / MD5 / SHA256- tar listing versus extracted structure count- presence of scripts / figures / macros / pyproject.toml / uv.lock- read-only script I/O surface before execution This record does not mirror or redistribute the original paper, data release, analysis bundle, posterior samples, scripts, or source data. EV424 does not certify the scientific truth of the paper, does not claim endorsement by LIGO, Virgo, KAGRA, LVK, Zenodo, CERN, or the upstream authors, and does not claim that full notebook execution or posterior recalculation was completed in this v0.1.0 record. EV424 scope:official source → checksum → structure → receipt → recheck path Accuracy(4)=Truth(2)=Life(4)
