r.referenceData(...)
Overview
Section titled “Overview”r.referenceData(entity, rows, options?) — declares static lookup rows
for an entity, upserted by seedReferenceData (the app or dev-server
calls it at boot — not the framework itself): insert or update by
upsertKey — which defaults to the first field of the first row, so
declare it explicitly — and never delete. New rows land under
SYSTEM_TENANT_ID, i.e. global reference data, not tenant rows.
