Hi Luc, > I don't understand your multiple granularities. Can you explain? I mean, to use an old example, that a cake may be reasonably be asserted to be generated by a BakeCake execution and also by a CookInOven execution, because the latter is a finer grained description than the former. The assertions could be by the same asserter or two different asserters. Before accounts are mentioned, this seems perfectly reasonable - why would we disallow such a description? However, we have a restriction that, for an account to be valid, each entity can only be generated by one execution within that account. This suggests to me that he restriction is about accounts and their validity rather than generation events.
