function dilutedBalance(uint112 amount) internal view returns (uint256) {
    // duration / timeRemaining * amount
    if (block.timestamp < startTime) {
        return amount;
    } else {
        uint32 timeRemaining = endStream - uint32(block.timestamp);
        return ((uint256(streamDuration) * amount * 10**6) / timeRemaining) / 10**6;
    }
}

Recommendation

Change to:

function dilutedBalance(uint112 amount) internal view returns (uint256) {
    // duration / timeRemaining * amount
    if (block.timestamp < startTime) {
        return amount;
    } else {
        uint32 timeRemaining = endStream - uint32(block.timestamp);
        return ((uint256(streamDuration) * amount * 1e6) / timeRemaining) / 1e6;
    }
}
