* - marking the taken dose as not taken, correcting it and deleting it each
* remove the day's SUPPLEMENT row; a changed composition recomputes the
* history; an automatically recorded dose counts;
* - the recompute is idempotent, writes nothing with the module off, and a
* deleted medication takes its rows with it;
* - the label read is refused without a provider, under the operator's
