AttributeRowValue

One attribute on one row, as the projection carries it: the value's shape in kind and its canonical string in value.

kind is one of date, datetime_floating, datetime_zoned, number, bool, ref, url, text - three temporal tokens, and no `datetime` that might be either ([ADR-183]). value is the canonical string for that kind: a calendar date as YYYY-MM-DD, a floating wall clock as YYYY-MM-DDTHH:MM:SS, a zoned instant as decimal epoch-ms, a tag as its TagId.

Type object

Shape

Field	Type	Description
idrequired	string	The attr record's own id, stable across edits to its value.
rolerequired	string	The attribute key the value is stored under - `koru.due`, `koru.tag`, or a custom definition's key.
kindrequired	string
valuerequired	string
zone	string or null	The IANA zone a `datetime_zoned` value was meant in, and absent for every other kind. It travels with the instant rather than being dropped as presentation: a consumer handed an epoch-ms number alone would be holding the ambiguous shape the three types exist to abolish. Which zone a reader displays it in is that consumer's own, separate decision.
label	string or null	Default `null`

Example

}

The contract has no example values, so example bodies are generated from each schema: every field is shown with a placeholder of its type.
