  "claim_text": "Tick 1940 advances GAP-12 from stub to a versioned interface contract for scidex.donors.resolve. The verb accepts a list of {cohort, external_id} pairs where cohort is one of {SEA-AD, ROSMAP, Mathys2023, ADNI, PPMI, UK-Biobank} and external_id is the cohort-native string identifier. It returns {canonical_uri, provenance_chain, match_confidence, cohort_crosswalk} where canonical_uri is a scidex-namespaced donor IRI, provenance_chain records each mapping step as a signed assertion (source cohort, mapping rule, resolver version), match_confidence is one of {exact, probabilistic, unresolved}, and cohort_crosswalk lists all known sibling identifiers across registered cohorts. Identity-graph schema: nodes are donor URIs; edges carry {relation: same_donor|probable_same_donor|same_biological_sample, evidence_type: direct_linkage|phenotype_match|genomic_fingerprint, confidence_score: float[0,1]}. GA4GH DRS alignment: canonical_uri is structured as a DRS-compatible URI (drs://{host}/donors/{uuid}) enabling federated resolution without substrate lock-in. Disambiguation rule: when match_confidence=probabilistic, the resolver emits a disambiguation_required flag and halts downstream joins until a curator or automated fingerprinting step promotes to exact. Platform action: register this contract as a substrate verb spec artifact and link to GAP-12 claim chain.",
