Write the fill value into every sample an assembled output is missing.
Two kinds are missing, and only the whole output knows both. Inside it are the holes a bridged gap left, whether the members were merged across one or a single member carried one of its own. Outside them are the edge positions a window laid over a hole advertises but no source feeds. A row stating no evenly sampled window (a descending coordinate, whose direction an envelope cannot express) keeps the interior fill and is not padded.
