PythResolver.sol

Handles Pyth oracle integration for deterministic market resolution.

resolveMarket(marketId, updateData)

1. Verifies market is in Closed state

2. Calls parsePriceFeedUpdatesUnique(updateData, priceId, T, T+Δ) on the Pyth contract

3. Confidence check: reverts if conf > confThresholdBps × |price| / 10000

4. Sets pendingResolution with the parsed price and publish time

5. Records resolver address for bounty payment

finalizeResolution(marketId)

1. Verifies at least n+2 blocks have passed since resolveMarket (finality gate)

2. Checks if any challenger submitted a better (earlier) update during the window

3. Determines outcome: price > strike → YES wins; price ≤ strike → NO wins

4. Transitions market to Resolved

5. Pays resolver bounty

challengeResolution(marketId, updateData)

During the finality window:

1. Submit alternative Pyth update data

2. Contract verifies it's valid and has an earlier publishTime within [T, T+Δ]

3. If earlier, replaces the pending resolution

4. Challenger becomes the new resolver (gets bounty)
