Replication materials for testing maritime signals for local food-price early warning in Yemen

This anonymized record contains the data and computational materials supporting a manuscript that evaluates whether monthly maritime indicators improve short-horizon forecasts of relative local staple-price stress in Yemen. The deposit comprises two files: Source Data.zip — figure-level source datasets and a cryptographic integrity manifest supporting the figures and reported results. YEMEN LIFELINE Reproducibility Package.zip — executable analytical code, environment specifications, governed derived inputs, locked numerical outputs, figure-generation scripts, provenance records, source-audit routines and manuscript-alignment verification procedures. Running python run_reproduction.py regenerates and verifies 19 numerical outputs and nine analytical figures. The validation workflow also checks the registered upstream-source hashes and verifies agreement between the reproduced outputs and the reported tables and figures. Provider-governed or third-party upstream files that cannot be redistributed are documented through their source, filename, file size and SHA-256 checksum. Users must obtain such upstream files directly from their original providers and comply with the applicable provider terms. This record has been anonymized for peer review. Creator names, affiliations and final citation metadata will be updated after completion of the review process. The CC BY 4.0 licence applies only to original materials created for this deposit; third-party data remain subject to the terms and licences of their original providers.
