StabilizerNode.stabilize will revert when latestSample < priceTarget.
In StabilizerNode.stabilize, when exchangeRate > priceTarget and _msgSender is not an admin and not whitelisted, it asserts livePrice > minThreshold.
And minThreshold is calculated as follows:
This code snippet assumes that latestSample >= priceTarget. Although exchangeRate > priceTarget, exchangeRate is the malt average price during priceAveragePeriod. But latestSample is one of those malt prices. So latestSample can be less than exchangeRate and priceTarget, so stabilize will revert in this case.
Use minThreshold = latestSample + (((priceTarget - latestSample) * sampleSlippageBps) / 10000) when priceTarget > latestSample.
