## What it does

* Creates short prediction rounds (`5-15` minutes).
* Accepts user participation on two sides: `YES` and `NO`.
* Resolves outcome using Uniswap v3 TWAP direction between round start and round end.
* Supports claim-based payouts for winners (or refunds for void rounds).

## Round lifecycle

1. Operator creates a round for a Uniswap v3 pool.
2. Users participate on `YES` or `NO` while round is open.
3. After end time, anyone can resolve the round.
4. Users claim payout or refund.

## Resolution rules

* `YES` wins if end TWAP tick > start TWAP tick.
* `NO` wins if end TWAP tick < start TWAP tick.
* Round is voided when:
  * end TWAP tick == start TWAP tick, or
  * one side has zero stake.

## Payout rules

* Non-void rounds:
  * Total pool = `YES stake + NO stake`.
  * Protocol fee is deducted from total pool.
  * Remaining amount is distributed to winners proportionally by winning stake share.
* Voided rounds:
  * Each participant gets full refund of their own stake.

## Access model

* Owner manages operators, protocol fee, pause/unpause, and protocol-fee withdrawals.
* Operators create new rounds.
* Anyone can resolve ended rounds and claim own payout.
