Insert
data class Insert(val path: String, val value: <Error class: unknown class>? = null, val values: List<<Error class: unknown class>>? = null, val index: <Error class: unknown class>? = null) : MutationAction
Add to an array — exactly one of value (a single element) or values (several). Appends by default; index inserts before that position, clamped to the length. An absent target becomes a new array.
