California State Controller's Office - Baseline postal outreach route - DAI RUHUAcontact_route
Baseline viable outreach route added by Maestro. Batch: agent:1000_route_mix:20260531-224715 Route: postal mail to imported primary-owner address. Owner: DAI RUHUA Address: 15615 ALTON PKWY STE 450, IRVINE, CA 92618 Balance bucket: high Balance: $1,032,243.37 Caveat: address is from the ClaimDesk imported California unclaimed-property owner record and was not independently current-verified in this baseline 1,000-record pass. No outreach was sent or queued.
- Contact trace: no usable route for DAI RUHUAcontact_trace
Contact trace found no usable Dai-specific route. Old listed address 15615 Alton Pkwy Ste 450 appears to be a multi-tenant/business mailbox/office location: Bizprofile lists 41 registered entities there with no visible Ruhua Dai match; MapQuest search result identifies the suite as Premier Workspaces. That operator/address clue is not enough to persist as an owner contact. People-search sources were blocked by bot/security pages and not bypassed; general exact-name web searches did not yield a current address, phone, SMS, business, registered-agent, or successor route tied to Ruhua Dai.

California SCO Unclaimed Property Search - ClaimTrace research scoring summarymemo
Imported from ClaimTrace v2 research scoring: 52/100 (51.5/100 adjusted points). Plan ID: d4915018-dd4a-4acd-a185-dd96a88eabc0 Status: in_progress Category scores: - claim_status: 11.9/20 — SCO mirror indicates active property listing status. Pending claims count=1; paid claims count=0; assigned estates source attempted without active linkage. All assigned claim-status sources were attempted. - owner_identity: 8.4/20 — SCO owner rows provide a baseline owner identity; non-SCO assigned sources were attempted but did not yield deterministic corroboration in this run. - legal_entitlement: 5.31/20 — Assigned legal-entitlement sources attempted (count=2). 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: 12.45/20 — Assigned contactability sources attempted (count=2). A mailing-address route is present in source mirrors. At least one source produced a positive contactability signal. Multi-source assignment slightly increased confidence while preserving caution. - property_context: 7.38/10 — Property context sources attempted (count=1). Holder context=BANK OF AMERICA NA; property_type=CK15. 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: 6.06/10 — Official SCO requirements identified; burden driven by high-value notarization, pending claim activity.
