And I think that extra flush is something XML::Twig documents as being required in some circumstances anyway, IIRC.

Correct. According to the XML::Twig docs, "if you use flush at any point during parsing, the document will be flushed one last time at the end of the parsing, to the proper filehandle."

For example, updating _move to be:<snip...>

That is essentially what I ended up doing in my final code to work around the problem:

sub _move {
    # Skip this section if no "<slip>" descendants are found
    if ( !scalar $_[1]->descendants('slip') ) {
        $_[1]->delete;
        $_[0]->purge;
    }

    # "<slip>" descendants found, process as normal
    else {
        <...>
        $_[1]->delete;
        $_[0]->flush();
    }
        
    1;
}

This appears to work, but I don't know why it works, or even what the root problem is. It all feels very cargo-cult right now...
