Analysis Rule Sensitivity in Bell and GHZ Experiments: A Reproducible Audit Framework

This paper synthesizes two published audit lines into a single reproducible framework for Bell and GHZ interpretation under analysis-rule sensitivity. Using public records and artifact-linked evidence, we show that Bell/CHSH on the same NIST event stream shifts from S_strict=2.336276 to S_standard=2.839387 (Delta=+0.503111) under protocol change, while GHZ search under the current audited pipeline remains far from F=4 (best fine-stage F=0.085396). We formalize a ledger-style audit protocol that treats pairing windows, denominator policy, post-selection, and uncertainty as first-class reported variables. We further introduce a singles-aware diagnostics layer (C_norm = coincidences / sqrt(singles_A * singles_B)) as a testable bridge for normalization-path analysis, while explicitly avoiding ontology-level promotion from current evidence. The contribution is a publication-ready, boundary-aware audit standard with claim-to-artifact traceability across both lines.
