Fix
A refunded purchase now appears in your credit history
When a credit pack or a subscription was refunded, the credits came back out of your wallet — correctly — but nothing was written to your credit history. The balance simply dropped, and the one screen whose job is to explain where credits went had no line for it. That was also the only kind of credit loss you did not cause yourself, so it was the one most in need of an explanation.
Refunds are now recorded like any other movement, with the amount and the date, and they are excluded from the spending-rate figure — money going back to you is not consumption, and counting it would have inflated the burn rate and the runway projected from it.
