blob/allocate should have receipt as cause instead of blob/add task

[vasco-santos]

See context: storacha/w3infra#353 (comment)

link to the signed receipt as opposed to invocation. In a way all our stores should simply be indexes over receipts because receipts are signed commitments from us, also they do link back to the corresponding invocation.

I believe the problem we currently would have to implement this is our lack of ability to have the link to the signed receipt at the point in time that allocate happens. But I may be missing something, what do you think @Gozala ?

Ah I suppose that is because ucanto takes care of creating them for us ? I guess we just need to allow returning receipt from the advanced handler in which case this will no longer be an issue.

BTW I think this issue description is very confusing, my original comment was suggesting that listing blobs should return list of receipts, not that blob/allocate should have cause field linking to the blob/add receipt because that would introduce a cycle.

I think you are not correct on this. You also gave that feedback, which I also agree, but please have a look on the referenced comment with context on first message of the issue 😅

Sorry I was not very clear with what I was talking about when I expressed that links should be to a receipts. I was trying to say that we should be storing blob/allocate receipts in the store as store is effectively an index over those receipts and I think you mistook it for me saying that we should link to blob/add receipts which would not be possible because it does not exist at the time of allocation.
