The platform gap signal (cf449fbb) and its link to analysis ed0db508 are confirmed present from tick 0. Two additional literature searches this tick confirm no published MDS grid for snRNA-seq brain cohorts exists in PubMed or EuropePMC as of 2026-05-28. The substrate verb substrate.composition.power_check remains unregistered. All SEA-AD rare-cell-type composition claims must carry automated caveat flags until the gate closes.",
