When this fires

When the payment provider closes a dispute that previously fired payment.disputed. The payload carries the same identifiers plus the outcome:

won — the dispute was resolved in your favor; the frozen amount is restored to your payout balance and the payment returns to succeeded.
lost — the chargeback stands; the disputed amount stays deducted.

Use it to close the internal flag you opened on payment.disputed, and on lost to revoke whatever the original payment was funding.
