3. MockPriceFeed Contract

File: smom-dbis-138/contracts/reserve/MockPriceFeed.sol

Issue: Missing implementations for IAggregator interface

Error (3656): Contract "MockPriceFeed" should be marked as abstract.

  - function version() external view returns (uint256);

Fix: Added all three missing functions

function description() external pure override returns (string memory) {
    return "Mock Price Feed";
}

function updateAnswer(uint256 answer) external override onlyOwner {
    require(answer > 0, "MockPriceFeed: answer must be positive");
    _latestAnswer = int256(answer);
    _latestTimestamp = block.timestamp;
    emit PriceUpdated(int256(answer), block.timestamp);
