The Bitrise guide on artifacts doesn't specify how long they will be accessible in the build. Are they permanent, or will they expire after a certain amount of time?

Right now we don’t have a hard limit, you can store unlimited builds & build artifacts. Of course, if someone abuses the system we’ll contact them, but for normal use it’s “unlimited”.
We might introduce some kind of limit in the future, but we don’t have any plans for that right now.
