FLX-3202: row is missing a required column
Family: seam/conformance (the 3000 band)
The referenced FLUID contract marks this column required, and the row carries no value for it -- either absent, or present as null. A required column whose value is null carries no value, so admitting it would let a stream satisfy the contract with a column of nulls.
