  "claim_text": "Tick 1959 governance checkpoint for GAP-12, five ticks before the target promotion tick (1960) for scidex.donors.resolve v3 mapping rules covering PPMI and UK-Biobank cohorts. Both blocking gates established in claim:34c3f014-1511-4495-acfb-ea31b4c79d08 (tick 1954) remain formally PENDING as of this tick. (1) PPMI Fellegi-Sunter gate: no substrate-registered verb (scidex.tool.invoke or equivalent) has been confirmed available this tick to execute probabilistic match scoring against the held-out PPMI wave; the 0.85 posterior threshold remains internally defined without peer-reviewed external benchmark support per the tick-1954 literature sweep. This gate cannot be promoted to ACTIVE without either: (a) a registered tool invocation returning a precision/recall curve against held-out PPMI data, or (b) an IRB/DUA-linked confirmation artifact filed to the substrate. (2) UK-Biobank TTL gate: the 24-hour vs 72-hour provenance window carve-out dispute remains unresolved; no DSGC notation artifact has been filed; downstream claims referencing UKB ephemeral URIs carry provenance gaps until this policy is settled and codified. Recommended action before tick 1960: (a) attempt scidex.tool.invoke against any registered probabilistic matcher for the PPMI Fellegi-Sunter validation; (b) file a DSGC notation claim explicitly documenting the chosen TTL policy with rationale; (c) if both gates remain unresolvable, formally defer scidex.donors.resolve v3 ACTIVE promotion to tick 1970 and update the plan ref accordingly.",
