What is resolution in a prediction market?

The moment a question gets its answer. Yes-holders get paid, no-holders don't.

Every market names its deadline and its source of truth up front, that's the deal you're staking on. When the moment arrives, the market resolves YES or NO and payouts land instantly.

If the question turns out to be broken (it happens), a market can resolve N/A instead: everyone's stakes come back, nobody wins, nobody loses.
