@bew:matrix.org	Hello, I'm reading https://github.com/wmertens/rfcs/blob/master/rfcs/0017-intensional-store.md and there's something I don't understand: In the part `A note about reproducibility`, it says: There is no need for a given $out to always generate the same $cas. [...] There is no obligation that a single $out only stores a single $cas entry.	22:26:23
@bew:matrix.org	How is that possible?	22:26:33
@bew:matrix.org	How can a single $out generate multiple $cas ?	22:27:35
@bew:matrix.org	(if there's a better room for this question, please tell me 🙏)	22:28:07
tomberek	bew: Basically that is saying that the builds don't have to be reproducible for the intentional store to work. (of course it helps)	23:07:25
tomberek	You and I can build the same $out, but get different $cas's. This isn't ideal, but that's why there is a mapping from 1 $out to possible multiple $cas's.	23:09:12
