  "claim_text": "Five independent literature sweeps across PubMed, EuropePMC, and the SciDEX substrate (ticks 2, 8, 135, 174, 175) have returned zero published standalone crosswalk tooling or schema for AMP-AD / SEA-AD / ROSMAP donor identifier federation. The 2024–2025 date-restricted arms (tick 175) returned empty result sets from both PubMed and EuropePMC, confirming that no recent publications have filled this gap. The substrate search arm returned only the two prior GAP-11/GAP-12 closure claims from ticks 135 and 174 — no new internal specification has been shipped. GAP-12 (scidex.donors.resolve) is hereby escalated from 'literature-confirmed gap' to 'RFC-ready': the absence of prior art over five sweeps spanning approximately 175 ticks is sufficient justification to draft the verb specification without a blocking literature dependency.",
