make conditions for finalizing a proposal more robust

[0xbigz]

currently only twaps need to be higher by threshold for proposal to pass. just relying on the twaps as currently implemented might be too easy to game.

i wonder if its better to also ensure that

1. mid price (and/or bid, ask) of the market is consistent with the twap differences (including threshold?)
2. allow way to pay to extend proposal (opposite to fee cooldown to launch a new proposal?)

this consistency check wouldn't change whether a proposal passes or not, but just delays finalizing. this gives ample time to for those who really disagree with a proposal to exit before it's allowed to pass.

what does it mean for it to be consistent?

I feel like the exit mechanism is the conditional-on-pass market - you can dump your META in the conditional-on-pass market so that you're guaranteed that you will have sold if it passes

consistent definition: twap differences between conditional markets matches some 'live price' difference between conditional markets (essentially making the price check more robust)

'live price' could mean something strict like mid price for both markets
OR less strict like ask for pass market and bid for fail market.

for example in strict case, lets say pass twap > fail twap but current fail mid > pass mid
that likely means there are orders that should be placed/cleared before allowing finalizing the markets.

in less strict case, lets consider the following example:

Pass Market: bid=$100, ask=$110 (twap = 90)
Fail Market: bid=$100, ask=$110 (twap = 90)

• user vehemently disagrees with pass market
• in the last few hours leading up to proposal end time, the pass market has surged vs fail market

Pass Market: bid=$200, ask=$210 (twap = 145)
Fail Market: bid=$100, ask=$110 (twap = 105)

• user notices fairly late and places fat sell wall in pass market (they are bearish the proposal) and fat bid wall in the fail market

Pass Market: bid=$100, ask=$105 (twap = 145)
Fail Market: bid=$109, ask=$110 (twap = 105)

with the new consistent check rule, other users must buy that sell wall before the proposal can end. if no one is willing to buy it up, then the proposal end time is essentially ended and the fail market still has a chance to win.
