X_ENTITY_TENANT_UNDECLARED
Means
a child of a tenant-owned table has no tenant
Typical cause
an entity with no tenant column references, directly or through other entities, an entity that has one, and declares no shared reason, so a row of one tenant is readable by id from another
Fix
add orgId: uuid().tenant() to the entity, then x db gen '<table> tenant'; or declare shared: '<why it belongs to no tenant>'
