Subject: [PATCH 3/8] Catch negative size earlier
This now does catch the negative size inside the interface so that an
`op.emitError` can be thrown. That works, but then continues to
return an empty result?
Instead, the interface can probably be refactored first because it's
very restrictive in its current form.
