Every headline retrieval number reported in the paper is mapped to a concrete on-disk artifact through a system registry and a claim-to-asset traceability matrix. The matrix points each reported result to files under three named directories: \path{outputs/} (run-level retrieval outputs), \path{data/processed/} (processed split and graph artifacts), and \path{reports/} (rendered tables, latency logs, and bootstrap summaries). This makes each headline number independently auditable against a named file rather than only against a row in the paper.
