California SCO Unclaimed Property Search - ClaimTrace research scoring summarymemo
Imported from ClaimTrace v2 research scoring: 54/100 (53.5/100 adjusted points). Plan ID: d73d81c2-2a90-45b0-8b5e-162f5992891a Status: in_progress Category scores: - claim_status: 16.2/20 — SCO mirror indicates active property listing status. Pending claims count=0; paid claims count=0; estate source not assigned for this category. All assigned claim-status sources were attempted. - owner_identity: 8.84/20 — SCO owner rows provide owner identity evidence with no additional assigned sources required. - legal_entitlement: 5.31/20 — Assigned legal-entitlement sources attempted (count=1). No deterministic authority record was confirmed in automation; path remains document-dependent. Court/entity/document requirements remain partially unresolved pending record-level follow-up. - contactability: 9.75/20 — Assigned contactability sources attempted (count=1). A mailing-address route is present in source mirrors. At least one source produced a positive contactability signal. Confidence was explicitly restrained because only one source was assigned. - property_context: 7.38/10 — Property context sources attempted (count=1). Holder context=WELLS FARGO BANK NA (APECS 1009); property_type=AC02. Holder and property-type context are both present in the SCO mirror baseline. County/locality context exists for routing and prioritization. Assigned sources produced a favorable context profile. - claim_requirements: 6.02/10 — Official SCO instructions identify the core document package; row-specific burdens are driven by high value, property type, owner/trust/government status, multi-owner signatures, and pending claim indicators.
