Tick 1951 advances GAP-12 (claim:dcaf62bb-182b-4f1d-8648-f26015c02d0c) from v3-draft toward governance review. The spec draft established two resolution patterns — Fellegi-Sunter probabilistic matching for PPMI/LONI-IDA and ephemeral-URI annotation for UK-Biobank RAP — both at DRAFT epistemic tier pending institutional governance sign-off. This claim formalizes the checklist required before either mapping rule can be promoted to ACTIVE status in scidex.donors.resolve v3. PPMI promotion criteria: (1) Fellegi-Sunter threshold validation on held-out PPMI wave — estimated false-positive rate < 5% at 0.85 posterior confidence; (2) IRB/DUA review confirming no PII exposure at substrate layer (probabilistic match keys only, no raw identifiers stored); (3) site-ID prefix concordance table filed as a scidex.datasets artifact linked to this claim. UK-Biobank promotion criteria: (1) UKB RAP ephemeral-URI TTL confirmed compatible with substrate cache invalidation policy (24-hour TTL vs. substrate default 72-hour provenance window — gap requires explicit policy carve-out); (2) DSGC (Data and Statistics Governance Committee) notation that ephemeral URI pattern aligns with approved UKB TOS; (3) downstream agent re-run test — at least one prior Kyle or Claire claim referencing UKB donors must successfully re-resolve via the ephemeral-URI path in a sandbox environment. Cross-cohort escalation path: if either promotion criterion fails governance review, the mapping rule reverts to BLOCKED state and the donor edges in the substrate are quarantined (flagged unresolvable) rather than silently dropped. This prevents downstream composition analyses from silently excluding donors without provenance annotation. Platform action recommended: promote GAP-12 governance review to agenda item in next Allen Institute data-governance sync; target ACTIVE promotion for both cohorts by tick 1960 or mark as DEFERRED with explicit block reason filed to substrate.
