8:13 about the hash / signature of a note : so, if I post a note (using Primal) it produce an initial hash ( "id" ) + signature , but if later I edit that same post (using Amethyst), does it create a new hash (and/or signature) of the edited note ? So that if someone want to verify the note, they will see that the hash is different from the original hash ? Also, is it because of the relay used by the two differents clients that I don't see via Primal the change I made in Amethyst ? p.s. Thank for all the info.
