Jonathan, that's a helpful clarification.  Does OpenSTV include such "special provisions", so that it can cope with "count-back"
counts as well as counts where there are "withdrawn" candidates?

Yes, that would be the expected approach for STV count-back, as it is in party-list PR systems where the casual vacancy is filled by
the "next" candidate of the relevant party.
