const val UNKNOWN: Int

PartiallyKnownDocumentMultiPointer.UNKNOWN — IIdentifier.UNKNOWN, source-verified as -5 in kernel 30.8.1. Not an index and not a wildcard: it marks a level the engine could not resolve to a row, which a parallel iteration produces when one joined group has no row carrying the current index value.
