Proposer | Make permission request easier | Android library

I am trying to implement a Bayesian estimator for the card game Avalon. The game has five rounds and each round contains at most five proposals made by five different players. If a proposal is accepted, players go on a quest and the game proceeds to the next round. Before the previous round is completed, it is not known which 5 players will get to propose teams in the next round. I wanted to keep track of the current player that gets to propose a team using an iterator, but somehow it ends up pointing to nowhere. Specifically, in the constructor called for round1, the iterator Round::proposer points correctly to &PlayerA, the beginning of Round::proposers. However, when I add this instance (or a copy of it?) to Game::rounds, then the Round member proposer of Game::rounds.back() points nowhere, even though the Round member proposers is still correct. Why does that happen? During execution, of course a read access violation exception is thrown during the call (*Round::proposer)->make_proposal();. I apologize for the lengthy question, but two levels of indirection seemed necessary to produce the error.

Consider the following flow :

Proposer prepares a message, gets a promise, sends a proposal with some value, gets it accepted. All fine.

After acceptance, another proposer comes along and prepares a message with a higer id, and the same flow continues.

Is this a valid flow of a single round of the paxos algorithm? Or is this actually multi paxos?

So I'm building a simple voting system as a DAML beginner and it's working quite good so far. Now I set conditions stating that a decision is allowed to be made when 60% of the registered voters have voted (which can be found in choice Decide below). However, when I leave out any of voters while meeting the 60% condition I get the following error stating that there's an authorized voter missing:

Contrary to Ethereum which uses RANDAO (possibly enhanced with VDF), in Polkadot, a verifiable random function (VRF) is used to shuffle validators and select potential block proposers for certain slots. Where does the randomness come from, i.e. how does the randomness work specifically?
