Ophelia and a State Pension

Since Ophelia Ford was seated and allowed to vote in the State Senate for at least three or four months, doesn't that qualify her for a State pension and medical benefits for life now?

Since her election was voided, it seems wrong and unfair. But can the Senate revoke something like this, if in fact it will happen?

And won't her temporary replacement also get a life pension and medical benefits? I'm thinking of the gold mine that Sidney Chism got when he did the substitute legislator thing last year.
