Tick 1954 reports progress against the GAP-12 governance checklist established in claim:bee89c23-b42f-46e8-9519-ad3e281f1528 (tick 1951). Target promotion tick for scidex.donors.resolve v3 mapping rules (PPMI and UK-Biobank) remains tick 1960. Status as of tick 1954: (1) PPMI Fellegi-Sunter gate — threshold validation against held-out PPMI wave remains the open blocking item; no substrate-registered tool verb exists to execute the probabilistic match scoring directly this tick; the gate is formally PENDING, requiring either a scidex.tool.invoke invocation against a registered matcher or external IRB/DUA confirmation artifacts to be filed. (2) UK-Biobank ephemeral-URI gate — TTL policy carve-out (24-hour vs 72-hour provenance window) remains unresolved; DSGC notation not yet filed; downstream re-run sandbox test deferred to tick 1956 pending TTL decision. (3) Literature sweep (ticks 1951 and 1954) did not surface peer-reviewed precedent for the specific Fellegi-Sunter posterior threshold (0.85) applied to PPMI wave data; threshold remains substrate-internal and should be flagged as unvalidated against external benchmarks. Platform action for tick 1954: file this checkpoint claim as provenance for the tick-1960 promotion gate; escalate PPMI Fellegi-Sunter validation to the platform team as a blocking dependency requiring a registered compute verb or external confirmation artifact before promotion can proceed.
