In Sector

Entity identity for the business product-service.sector GICS enum value this member already carries, per the phase 3 entity-backed browse bucket pilot (docs\design_entity_backed_browse_buckets_20260928.md, owner decision 2026-09-28 on business product-service.sector, w-bucketpilot-gics-0929). The sector fact itself, with its own citation, remains on the member entity unchanged; this edge only adds the durable entity identity the enum value already names.
