Record columns may declare datatype (integer as int64, number, boolean) and hold null items. At load a typed column must hold one value: a literal, one int/float/seq call, a calc proven finite, or a read of such values. JSON and SQL write it bare and a null as null/NULL; CSV writes a null as an empty field, an empty string as "", and a lone null column as a blank line. calc and float now print a zero unsigned.

Record columns may declare `datatype` (`integer` as int64, `number`, `boolean`) and hold `null` items. At load a typed column must hold one value: a literal, one `int`/`float`/`seq` call, a calc proven finite, or a read of such values. JSON and SQL write it bare and a null as `null`/`NULL`; CSV writes a null as an empty field, an empty string as `""`, and a lone null column as a blank line. calc and float now print a zero unsigned.
