Case	Answer	Resulting balance
The bet was debited	200 with the new balance	balance + bet
Same rollback again	200 with the first answer	unchanged
You never saw the bet	200 with the current balance; remember the id as cancelled	unchanged
That bet arrives after its rollback	4xx: refuse it	unchanged

Two kinds reach you: a provider cancelling a round, and our own rollback after your wallet stayed silent on a bet or win. Ours carries "<transaction_id>:rollback" as its id and the silent movement as reference_transaction_id.
