`resolve_relation_as_of`

Resolve what a relation into a versioned reference table reads as of a given release — so a document written against an earlier one keeps showing the labels it was written with. A null resolvedRowId means the stable key does not exist in that release: the row was added later, or removed. That is the answer, not a failure.

## Parameters

**columnId** `string` *required*

The oneMany column pointing at the versioned set.

**rowId** `string` *required*

The referring row.

**asOf** `string` *required*

The release to resolve against.
