Admin: a Lineage tab, the operator view of unresolved references (roadmap D20, remaining item 2). It lists what Live's canonical channel/owner resolver answered unresolved (conflict, source_unavailable, not_found, display_name_only), by reference and reason, with detail, last caller, count, and first/last seen, filterable by reason. It reads Live's GET /api/admin/lineage/unresolved (4479b66) through the existing admin-only /api/admin/streamer proxy.
